<p>President Obama fires a marshmallow gun and lets robots roam his White House at the <a href="http://www.whitehouse.gov/blog/2012/02/07/white-house-science-fair-recognizing-importance-scientists-engineers-and-inventors">White House Science Fair</a>.</p>
<p>Three-year-old Danielle Fairchild probably can&#8217;t grasp the magnitude of what she&#8217;s enabled. The little girl adopted by Fred and Dale Fairchild in Duluth, Georgia was born with half a thumb and no fingers on her right hand. Half-way across the country a smart teenager and five other girl scouts were looking for a science and technology project to complete.<div id="attachment_6110" class="wp-caption alignright" style="width: 335px"><a href="http://www.realscience.us/blog/wp-content/uploads/2012/02/DanielleFairchild.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2012/02/DanielleFairchild-e1328722252816.jpg" alt="Danielle Fairchild Writes with Help of Prosthetic Hand" title="DanielleFairchild" width="325" height="229" class="size-full wp-image-6110" /></a><p class="wp-caption-text">Danielle Fairchild Writes with Help of Prosthetic Hand</p></div></p>
<p>Dale Fairchild contacted Kate Murray and the troop of <a href="http://news.engineering.iastate.edu/2012/02/07/flying-monkeys-at-white-house-science-fair/">The Flying Monkeys</a> and a partnership was born. 13-year old Murray was born with a thumb but no fingers on her left hand. Despite this digital abnormality she took up the violin five years ago using a device that clips to the bow and wraps around her left palm. And she thought she could help someone else learn to write.</p>
<p>Upon hearing about little Danielle The Flying Monkeys flew into action, learning all they could about prosthetic limbs, talking to doctors and learning how to build one from scratch.</p>
<p>Fast forward to February 7 as Kate Murray, Gaby Dempsey and Mackenzie Gewell present their prosthetic hand device to President Obama in the White House at the second White House Science Fair.</p>
<p>As the President held the <a href="http://knowledgetoday.wharton.upenn.edu/2011/04/flying-monkeys-and-the-future-of-innovation/">BOB-1.2</a> plastic device in his hand, he said, &#8220;This is outstanding.&#8221;</p>
<p><div id="attachment_6109" class="wp-caption alignleft" style="width: 285px"><a href="http://www.realscience.us/blog/wp-content/uploads/2012/02/WhiteHouseScienceFair.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2012/02/WhiteHouseScienceFair-e1328722321305.jpg" alt="President Obama Pumps Air Cannon at White House Science Fair" title="WhiteHouseScienceFair" width="275" height="182" class="size-full wp-image-6109" /></a><p class="wp-caption-text">President Obama Pumps Air Cannon at White House Science Fair</p></div>Mr. Obama pumped Joey Hudy&#8217;s marshmallow air cannon before launching the blob of sugar 176 feet across the White House Dining Room. Over 100 students joined the President and top science advisers and department heads to shine a bright spotlight on science, technology, math and engineering.</p>
<p>The Flying Monkeys won a $20,000 Innovation award from For Inspiration and Recognition of Science and Technology <a href="http://www.firstlegoleague.org/">(FIRST) Lego League</a>. FIRST is the non-profit organization started by inventor Dean Kamen, who famously brought us the Segway. And for Murray a trip to the White House is &#8220;super exciting.&#8221;</p>
<p>She says, &#8220;I want to be a mechanical engineer when I grow up. I want to design cars to be more fuel efficient and/or rely entirely on wind or solar energy.&#8221;</p>
<p>14-year old Joey Hudy unwittingly stole the show providing spectacular photo opportunities as President Obama listened the story about how the Phoenix teen built his marshmallow air gun from PVC pipe with the help of employees at his local Home Depot. Then he asked if the device was operational and decided on the spot that the two should fire it together.</p>
<p>The President asked that everyone in the line of fire move back because this was an improvised activity while strolling through the student exhibits and talking to the winners of over 40 science fairs and competitions.<div id="attachment_6107" class="wp-caption alignleft" style="width: 238px"><a href="http://www.realscience.us/blog/wp-content/uploads/2012/02/WhiteHouseScienceFair4.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2012/02/WhiteHouseScienceFair4-e1328722442713.jpg" alt="Joey Hudy with President Obama Impressed by Power to Shoot a Marshmallow Missile" title="WhiteHouseScienceFair4" width="228" height="300" class="size-full wp-image-6107" /></a><p class="wp-caption-text">Joey Hudy with President Obama Impressed by Power to Shoot a Marshmallow Missile</p></div></p>
<p>When the gun popped, press cameras clicked wildly and they caught the child-like wonderment in the eyes of the President, which encapsulated the entire White House science fair.</p>
<p>Clearly, the President was impressed by the caliber of projects presented and the students themselves. He said, &#8220;Now, as I was walking around the science fair, I was thinking back to when I was your age. And basically, you guys put me to shame.&#8221; </p>
<p>President Obama lauded the whip smart students and their clever projects. But he was struck by something more.</p>
<p>He said, &#8220;It&#8217;s the fact that you recognize that you&#8217;ve got a responsibility to use your talents in service to something bigger than yourselves.&#8221;</p>
<p>He said some students will develop new products that change the way we live. He pointed out <a href="http://www.forbes.com/sites/kymmcnicholas/2011/10/07/16-year-old-social-entrepreneur-wins-national-competition-vowing-to-reduce-world-waste/">Hayley Hoverter</a>, the winner of the <a href="http://www.nfte.com/why/multimedia/videos/hayley-hoverter-sweet-dissolve">2011 Network For Teaching Entrepreneurship&#8217;s National Challenge</a>. The 16-year-old Los Angeles resident invented a flavorless, colorless sugar packet that dissolves in hot water.</p>
<p>About her invention the President said, &#8220;It could potentially save up to two million pounds of trash each year &#8212; and that&#8217;s just at Starbucks.&#8221; Mastercard gave the teen $10,000 to turn her concept into a working business.</p>
<p>Next the President said that some students will see a problem in their town or city and do something about it. After 14-year old <a href="http://www.broadcomfoundation.org/docs/competition_benjaminhylak.pdf">Benjamin Hylak</a> was worried that seniors in nursing homes would get lonely he built a robot attached to a computer monitor. His telepresence robot which moves around the center and allows seniors to connect via Skype with their family and friends qualified him as a <a href="http://www.societyforscience.org/MASTERS">BROADCOM Masters Competition</a> 2011 finalist.<div id="attachment_6116" class="wp-caption alignright" style="width: 184px"><a href="http://www.realscience.us/blog/wp-content/uploads/2012/02/AngelaZhang-e1328729827116.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2012/02/AngelaZhang-e1328729897386.jpg" alt="Angela Zhang Explains Her Nanoparticle Cancer Treatment" title="AngelaZhang" width="174" height="163" class="size-full wp-image-6116" /></a><p class="wp-caption-text">Angela Zhang Explains Her Nanoparticle Cancer Treatment</p></div></p>
<p>President Obama said, &#8220;Inventions like Benjamin&#8217;s could make life better for millions of families.&#8221;</p>
<p>The same holds for the three representatives from California.</p>
<p><a href="http://www.huffingtonpost.com/2012/01/15/angela-zhang-high-school-_n_1207177.html">Angela Zhang</a> of Cupertino, who has proposed a potential cure for cancer. This year, she won a $100,000 grand prize in the <a href="http://inr.synapticdigital.com/Siemens/Competition2011/">Siemens Competition in Math, Science and Technology</a> for her nanoparticle cancer treatment. She says, &#8220;I keep saying 60 years from now I will probably be telling my grandkids everything that happened when I was 17.&#8221;</p>
<p>Hayley Hoverter of Los Angeles, who developed sugar packets that dissolve in hot drinks is the now the 16-year old CEO of Sweet (dis)SOLVE. She spoke at <a href="http://www.youtube.com/watch?v=bgfT5EjVBNA">TEDx SoCal</a> last year. <div id="attachment_6111" class="wp-caption alignleft" style="width: 310px"><a href="http://www.realscience.us/blog/wp-content/uploads/2012/02/NeildeGrasseTysonBraedenBenedict.png"><img src="http://www.realscience.us/blog/wp-content/uploads/2012/02/NeildeGrasseTysonBraedenBenedict-e1328723222364.png" alt="Neil de Grasse Tyson with Braeden Benedict at White House Science Fair" title="NeildeGrasseTysonBraedenBenedict" width="272" height="300" class="size-full wp-image-6111" /></a><p class="wp-caption-text">Neil de Grasse Tyson with Braeden Benedict at White House Science Fair</p></div></p>
<p><a href="http://www.scienceofeverydaylife.com/views/video.cfm?entryGuid=0978f547-d97e-45a5-9f8c-01232cb5100c&#038;year=2011">Braeden Benedict</a> of Ranchos Palos Verdes designed a device to detect concussions in athletes after one of his football teammates experienced prolonged concussion symptoms and had to stop playing contact sports. The 15-year old designed a helmet-mounted sensory detector that turns red when an athlete is hit hard enough to cause a concussion. </p>
<p>He took the top prize in America&#8217;s 2011 Top Young Scientist competition at the <a href="http://www.youngscientistchallenge.com/mediaroom/20111005.html">Discovery Education 3M Young Scientist Challenge</a> where he won $25,000 for his efforts.</p>
<p>The President spoke of the adversity several groups of students overcame just to be at the science fair. A <a href="http://www.dallasnews.com/news/local-news/20120207-texas-border-town-students-win-obamas-admiration-for-rocket-building.ece">rocketry team from Presidio, Texas</a> came from the 4th poorest school district in the nation where most students speak English as a second language. Parents raised money to help the students make the trip to Washington D.C. Mr. Obama said they even sold a goat to make the journey to the White House.</p>
<p>He applauded the winners of the Michigan Regional Contest of the <a href="http://futurecity.org/">National Engineers Week Future City Competition</a>. Three Detroit students imagined a clean energy future for their city and while they were doing so their school burned down, forcing them to merge with another school while they completed their project. The team said, &#8220;(Future City) helps me make a better city to live in.&#8221; They designed there vision around a city following the theme of &#8220;Fuel Your Future: Imagine New Ways to Meet Our Energy Needs and Maintain a Healthy Planet.&#8221; <div id="attachment_6121" class="wp-caption alignright" style="width: 252px"><a href="http://www.realscience.us/blog/wp-content/uploads/2012/02/SamanthaGarveyObama.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2012/02/SamanthaGarveyObama-e1328730305880.jpg" alt="Samantha Garvey Tells President Obama about Mussels" title="SamanthaGarveyObama" width="242" height="250" class="size-full wp-image-6121" /></a><p class="wp-caption-text">Samantha Garvey Tells President Obama about Mussels</p></div></p>
<p>The President also acknowledged 18-year old <a href="http://www.nytimes.com/2012/01/24/science/after-homelessness-honors-from-a-national-science-fair.html">Samantha Garvey</a>, who has spent a lot of time with the President lately. The high school senior from New York made headlines after winning a spot in the semi-finals of the Intel science talent search. But more than her ingenious project studying mussel predation on Long Island she captured the attention of America because when she found out she was a semi-finalist she was homeless.</p>
<p>Since then she has appeared on television and sat in the First Lady&#8217;s box at the State of the Union Address last month. At the White House science fair the President announced that the teen would like to work for NOAA or EPA some day. Pointing at them he said, &#8220;This is Dr. Lubchenco. She is the head of NOAA. Lisa Jackson, right there, head of EPA. You might, you know, just want to hook up with them before you leave.&#8221;</p>
<p>The President said that all the students who participated in the science fair inspired him. He said, &#8220;It&#8217;s young people like you who make me so confident that America&#8217;s best days are still to come.&#8221;</p>
<p><div id="attachment_6124" class="wp-caption alignleft" style="width: 335px"><a href="http://www.realscience.us/blog/wp-content/uploads/2012/02/WhiteHouseScienceFair7.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2012/02/WhiteHouseScienceFair7-e1328730909496.jpg" alt="President Obama Tells Science Fair Students They Are Paving the Way to the Future" title="WhiteHouseScienceFair7" width="325" height="216" class="size-full wp-image-6124" /></a><p class="wp-caption-text">President Obama Tells Science Fair Students They Are Paving the Way to the Future</p></div>He went on to say, &#8220;When you work and study and excel. What you are doing in math and science. When you compete in something like this you&#8217;re not just trying to win a prize today. You&#8217;re getting America in shape to win the future. You&#8217;re making sure we have the best, smartest, most skilled workers in the world so the jobs and industries of tomorrow take root right here. You&#8217;re making sure that we will always be home to the most creative entrepreneurs, the most advanced science labs and universities. You&#8217;re making sure America will win the race to the future. So as an American, I&#8217;m proud of you. As your President I think we need to make sure your success stories are happening all across the country. That&#8217;s why when I took office I called for an all hands on deck approach to science, technology, math and engineering.&#8221;</p>
<p>Dale Fairchild says that before The Flying Monkey&#8217;s created BOB-1 for little Danielle to use as she learns to write the toddler used her right hand like a flipper. But after the molded plastic device arrived, complete with a Vel-cro(TM) strap to attached a plastic pencil holder, the girl began using her fingerless hand to pick things up.</p>
<p>The teen engineers have never met Danielle Fairchild but their prosthetic hand device is going through the expensive and lengthy patent process, placing the teen inventors on track to help many more people besides the little girl in Georgia. </p>

<p>When George Clooney was recovering from his second bout of malaria after vising Sudan last year he demonstrated that the tropical infectious disease can create a very unpleasant ten days but they don&#8217;t have to be life-threatening.</p>
<p>But in many parts of Africa, South America and Asia, it is a killer. The presumption is that malaria kills mostly children under 5. And that&#8217;s in part why the World Health Organization which tracks the disease placed its annual death toll at about 655,000. But new research just doubled the annual malaria kill to 1.2 million people per year.<a href="http://www.realscience.us/blog/wp-content/uploads/2012/02/MalariaMosquito.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2012/02/MalariaMosquito-e1328576353169.jpg" alt="Malaria Mosquito" title="MalariaMosquito" width="325" height="254" class="alignright size-full wp-image-6095" /></a></p>
<p>The news comes as a punch to the gut of large malaria eradication programs around the world. A study in the British journal <em><a href="http://www.thelancet.com/journals/lancet/article/PIIS0140-6736%2812%2960034-8/fulltext?_eventId=login">The Lancet</a></em> found that 42 percent of cases in 2010 appeared in people older than five who were previously uncounted by other tracking methods.</p>
<p><a href="http://www.healthmetricsandevaluation.org/about-ihme/team/christopher-jl-murray">Dr. Christopher Murray</a>, the Director of the Institute for Health Metrics and Evaluation (<a href="http://www.healthmetricsandevaluation.org/">IHME</a>) at the University of Washington and the study’s lead author says, &#8220;You learn in medical school that people exposed to malaria as children develop immunity and rarely die from malaria as adults.&#8221;</p>
<p>But that&#8217;s not what the new numbers are saying. This information is sure to be controversial but could shift the malaria prevention efforts to include adults instead of just children. </p>
<p>Immediately following the announcement last week, the <a href="http://blogs.voanews.com/breaking-news/2012/02/03/who-defends-its-numbers-on-malaria-deaths/">WHO disputed the new numbers</a>, saying IHME used unreliable verbal testimony, rather than clinical autopsies, to arrive at its figure. But this is not the first time IHME and the WHO have butted heads. Last year, the WHO quietly adjusted down their maternal mortality numbers by a whopping 34 percent (from over 500,000 to about 350,000) after the IHME released the <a href="http://www.healthmetricsandevaluation.org/research/project/global-burden-diseases-injuries-and-risk-factors-2010-study">Global Burden of Diseases, Injuries, and Risk Factors 2010 Study</a> in the spring of 2010. </p>
<p>Tom Paulson from Seattle-based blog <a href="http://humanosphere.kplu.org/2010/09/world-health-organization-eats-crow-cuts-maternal-death-numbers/">Humanosphere </a>says numbers in global health flow like the tide. He says, &#8220;When an organization wants to ask for help and more money to its cause, the numbers showing the need tend to rise. When you want to show that your project to reduce death or disease is working, the numbers tend to ebb.&#8221;</p>
<p>The IHME is an independent global health research center that began in 2007 with a $105 million grant from the Bill &#038; Melinda Gates Foundation, which also funded this malaria study.</p>
<p>While the study found the overall number of malaria deaths is higher than in earlier reports, the trend in malaria deaths is following a consistent downward pattern. Starting in 1985, malaria deaths grew every year before peaking in 2004 at 1.8 million deaths worldwide. Then the death rate began to fall. Between 2007 and 2010, the decline in deaths was more than seven percent each year.<div id="attachment_6094" class="wp-caption alignleft" style="width: 335px"><a href="http://www.realscience.us/blog/wp-content/uploads/2012/02/MalariaBedNet.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2012/02/MalariaBedNet-e1328576417160.jpg" alt="Insecticide on Bed Nets Kills Malaria Carrying Mosquitoes" title="MalariaBedNet" width="325" height="211" class="size-full wp-image-6094" /></a><p class="wp-caption-text">Insecticide on Bed Nets Kills Malaria Carrying Mosquitoes</p></div></p>
<p>Insecticide-coated bed nets and anti-malarial drugs get the credit for reducing the malaria mortality since 2004. And the global health community has spent billions of dollars trying to reduce those numbers to zero.</p>
<p><a href="http://www.healthmetricsandevaluation.org/about-ihme/team/alan-lopez">Dr. Alan Lopez</a>, Head of the School of Population Health at the University of Queensland and one of the study’s co-authors says, &#8220;We have seen a huge increase both in funding and in policy attention given to malaria over the past decade, and it’s having a real impact.&#8221;</p>
<p>He credits programs like Nothing But Nets, Malaria No More, World Health Organization’s Roll Back Malaria, and the Global Fund to Fight AIDS, Tuberculosis and Malaria with keeping the malaria mortality rate on a downward trajectory.</p>
<p>According to current IHME estimates, when the Global Fund to Fight AIDS, Tuberculosis and Malaria began in 2001 the world spent about $250 million a year fighting the disease. In 2009 that number rose to more than $2 billion a year. </p>
<p>India is in the process of revising its malaria mortality numbers, possibly up to 40 times what it was reporting. The <a href="http://articles.timesofindia.indiatimes.com/2012-02-04/india/31024354_1_malaria-deaths-malaria-like-high-fever-malaria-infection">Times of India</a> says that health officials will revise the number of Indians who die from the mosquito-borne disease every year to 40,297. Overall, the number of malaria infections hovers around 9.75 million per year.</p>
<p>The IHME study found that malaria killed 46,800 Indians in 2010. But the official numbers from India show those numbers at 1,023.</p>
<p>India&#8217;s <a href="http://nvbdcp.gov.in/">National Vector Borne Disease Control Programme</a> agrees with Dr. Murray&#8217;s study figures. It says only 11 percent of malaria deaths in India were in children. An official tells the Times of India, &#8220;As against Africa where most malaria deaths occur among the pediatric age group, in India it is mostly adults who succumb to malaria infection.&#8221;</p>
<p>Even the WHO says India has been under-reporting its malaria deaths. The WHO places malaria deaths somewhere in the 15,000 range still far fewer than the IHME study. India only counts a malaria death if the case goes to the hospital and the malaria parasite is found in the blood of the victim at the time of death.</p>
<p>The IMHE study uses a new method called a <a href="http://www.cghr.org/index.php/projects/million-death-study-project/what-is-verbal-autopsy/">verbal autopsy</a>. This includes asking the friends or relatives of the deceased if the patient had died of malaria. IHME and collaborators around the world published a series of articles in a special edition of <em><a href="http://www.pophealthmetrics.com/series/verbal_autopsy">Population Health Metrics</a></em> in August 2011 focused on advancing the science of verbal autopsy. In poor countries, the cause of death is often misidentified due to broken or incomplete medical infrastructure.</p>
<p>The WHO refutes the new malaria numbers largely because of the verbal autopsy, which it considers an unreliable verbal diagnosis <a href="http://www.who.int/bulletin/volumes/84/3/164.pdf">not particularly effective</a> when it comes to identifying adults with malaria.</p>
<p>WHO spokesman Gregory Hartl says, &#8220;Basically, there is no diagnosis done in laboratory or after death of how a person actually died. He says, &#8220;You rely on the verbal record of a friend or relative saying that X person died of fever, for example. However, we know that there are many different diseases which cause fever.&#8221;</p>
<p>And when learning about infectious diseases in medical schools doctors-in-training are taught that most people who survive malaria in the first five years of life have a much higher immunity to the mosquito-borne disease later in life. </p>
<p>Hartl says it is important to look more carefully at the sources and the quality of data before arriving at any conclusions that will require a policy revision. </p>
<p><a href="http://www.realscience.us/blog/wp-content/uploads/2012/02/MalariaAreasAfrica-e1328576199104.gif"><img src="http://www.realscience.us/blog/wp-content/uploads/2012/02/MalariaAreasAfrica-e1328576199104.gif" alt="Malaria Areas Africa" title="MalariaAreasAfrica" width="281" height="316" class="alignleft size-full wp-image-6093" /></a>In Africa, malaria is blamed in 25 percent of all deaths in children under 5. There a child dies from the disease every 30 seconds, according to accepted WHO figures. But that&#8217;s also where the progress of malaria drugs and mosquito nets can bee seen. According to the IHME study Tanzania and and Zambia saw malaria deaths fall by more than 30 percent between 2004 and 2010.</p>
<p>But <a href="http://www.healthmetricsandevaluation.org/about-ihme/team/stephen-lim">Dr. Stephen Lim</a>, University of Washington Professor of Global Health and IHME study co-author is worried that economic troubles in Africa could destabilize the progress being made against malaria. Between 2009 and 2011 IHME found that development aid for global health slowed. And in November the Global Fund to Fight AIDS, Tuberculosis and Malaria announced it would cancel its next round of funding, casting doubt over the future of malaria control.</p>
<p>Dr. Lim says, &#8220;If the Global Fund is weakened, the world could lose 40 percent of all the funding dedicated to fighting malaria.&#8221; He adds, &#8220;We need to think of ways to fill funding deficits in order to ensure continued progress on malaria mortality.&#8221;</p>
<p>Perhaps that&#8217;s why in the conclusion of the 30-year analysis of malaria mortality the researchers find, &#8220;Donor support, however, needs to be increased if malaria elimination and eradication and broader health and development goals are to be met.&#8221;</p>
<p>Alex Perry at Time magazine&#8217;s blog, <a href="http://globalspin.blogs.time.com/2012/02/06/is-malaria-twice-as-deadly-than-we-think-it-is/#ixzz1ldUXfx1K">Global Spin</a> explains that this isn&#8217;t the first time the people running developing world health campaigns have been shown to have only the loosest understanding of the problems they are tackling.</p>
<p>In 2005 India briefly held the top spot for number of AIDS patients at 5 million. By 2007 that number was revised to 2.5 million. Similarly Perry saw a statistic in 2009 that said there would be 5 million AIDS orphans in South Africa by 2015. He says this year that figure was quietly cut by three quarters.</p>
<p>He says, &#8220;Some people look at these statistical about-turns and smell a rat.&#8221; They blame global health campaigners for manipulating numbers to fulfill their own agenda &#8212; thereby creating the perception of a crisis to drive fund-raising.</p>
<p>He says, &#8220;But the disputed malaria figures would seem to reveal a different truth. In a world that sometimes seems wondrously connected, and where people worry about information overload, it’s a sobering thought that, more often than we’d like, we really don’t know what’s going on out there.&#8221;<div id="attachment_6096" class="wp-caption alignright" style="width: 240px"><a href="http://www.realscience.us/blog/wp-content/uploads/2012/02/MalariaPlasmodiumFalciparum.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2012/02/MalariaPlasmodiumFalciparum.jpg" alt="Malaria Plasmodium Falciparum Parasite in Blood under a Microscope" title="MalariaPlasmodiumFalciparum" width="230" height="247" class="size-full wp-image-6096" /></a><p class="wp-caption-text">Malaria Plasmodium Falciparum Parasite in Blood under a Microscope</p></div></p>
<p><a href="http://www.indepth-network.org/index.php?option=com_content&#038;task=view&#038;id=771&#038;Itemid=677">Dr. Bernhards Ogutu</a> at Kenya&#8217;s Medical Research Institute (<a href="http://www.kemri.org/">KEMRI</a>) says malaria figures are just as elusive there as the <a href="http://en.wikipedia.org/wiki/Plasmodium">plasmodium </a>parasite itself. He says he hears people say they have malaria when they may have another fever-causing disease. He believes that may lead to overestimating the malaria problem in some places.</p>
<p>IHME is advocating for more resources to fight what it believes is a bigger problem. But Perry says, &#8220;That seems premature before the WHO and the IHME have even figured out who is right.&#8221;</p>

<p>After several deaths of people in Cambodia, Vietnam and China recently, the bird flu is making a comeback in public discourse. Concerns are growing about the H5N1 strain of the influenza virus. A few years ago the world-sweeping swine flu stole headlines but the bird flu, which is much more virulent than it&#8217;s porcine cousin, has been spreading from poultry to people.</p>
<p>An <a href="http://www.thejakartapost.com/news/2012/01/19/vietnam-reports-1st-bird-flu-death-2-years.html">18-year-old duck farmer</a> in Vietnam died last week, becoming the first bird flu fatality in that country in two years. The <a href="http://www.who.int/mediacentre/news/statements/2011/pip_framework_20111229/en/index.html">World Health Organization</a> also reports that a <a href="http://www.rawstory.com/rs/2012/01/18/cambodian-toddler-dies-from-bird-flu-who/">two-year-old boy in Cambodia</a> died from bird flu after being exposed to sick poultry in his village. Those deaths follow quickly on the heals of a <a href="http://www.bbc.co.uk/news/world-asia-china-16372348">39-year-old Chinese bus driver</a> dying on December 31 just outside of Hong Kong. And a <a href="http://news.yahoo.com/indonesia-reports-second-bird-flu-death-070840663.html">24-year-old man and five-year-old toddler in Indonesia</a> also reportedly died from the bird flu this year.</p>
<p>The WHO says that makes 343 deaths from 582 cases of bird flu since 2003 when the virus first began hopping from birds to people.</p>
<p>But now growing fear over the necessary research to better understand this pathogen, which has a 60 percent mortality rate, is forcing bird flu scientists to take a 60-day break.</p>
<p>Researchers studying a more deadly version of the H5N1 virus that can be spread through the air voluntarily suspended their research for two months after bioethicists raised concerns of the virus being turned into a bioweapon.<div id="attachment_5950" class="wp-caption alignright" style="width: 335px"><a href="http://www.realscience.us/blog/wp-content/uploads/2012/01/H5N1fluvirus.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2012/01/H5N1fluvirus-e1327350297549.jpg" alt="Electron Micrograph of the H5N1 Influenza Virus" title="H5N1fluvirus" width="325" height="195" class="size-full wp-image-5950" /></a><p class="wp-caption-text">Electron Micrograph of the H5N1 Influenza Virus</p></div> </p>
<p>This deep concern began in late December when a <a href="http://www.guardian.co.uk/world/2011/dec/21/bird-flu-science-journals-us-censor">U.S. federal government scientific advisory board asked two peer-review journals</a> not to publish the papers if they explained how they were able to genetically modify the current, naturally-occurring strain of bird flu. The government scientists made the virus even more deadly by making it airborne.</p>
<p>Just days after that announcement and before the papers could be published, government advisers demanded the details be kept secret and not published in scientific journals to keep the information from falling into the wrong hands.</p>
<p>The scientists who created the deadlier H5N1 in the lab say they needed to know if the current strain has the potential to mutate into an airborne one. It does. They just sped up the process. Knowing that key piece of information will allow countries to take more severe measures to eradicate the newly emerging illness.</p>
<p>Now the story about bird flu has mutated as well, raising concerns that the manmade strain of the virus is now a bigger threat than the naturally-occurring one, which seldom hops from poultry to people.</p>
<p>In a <a href="http://www.nature.com/nature/journal/vaop/ncurrent/full/481443a.html">letter that appeared in both journals</a><em>Science </em>and <em>Nature</em>, several key bird flu researchers explain why they are temporarily halting their research.</p>
<p>The principal investigators at the labs where the bird flu research is being conducted say that perceived fear of the new manmade strain of the flu virus escaping the lab is making them push the pause button for 60 days.</p>
<p>Drs. <a href="http://www.erasmusmc.nl/MScMM/faculty/CVs/fouchier_cv?lang=en">Ron Fouchier</a>, <a href="http://research.mssm.edu/garcia-sastre/adolfo-garcia-sastre.html">Adolfo García-Sastre</a>, <a href="http://www.vetmed.wisc.edu/people/kawaokay/">Yoshihiro Kawaoka</a> and 36 others recognize that they and the rest of the scientific community need to more clearly explain the benefits of bird flu research and reassure the public that the biosafety measures taken minimize its possible risks.</p>
<p>They say, &#8220;We have agreed on a voluntary pause of 60 days on any research involving highly pathogenic avian influenza H5N1 viruses leading to the generation of viruses that are more transmissible in mammals.&#8221;</p>
<p>The controversial research that prompted government warnings and the voluntary research suspension centered around ferrets. The researchers proved that viruses possessing a haemagglutinin (HA) protein from highly pathogenic avian H5N1 influenza viruses can become transmissible in ferrets.</p>
<p><div id="attachment_5952" class="wp-caption alignleft" style="width: 335px"><a href="http://www.realscience.us/blog/wp-content/uploads/2012/01/H5N1fluvirus1.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2012/01/H5N1fluvirus1-e1327350577599.jpg" alt="Scanning Electron Microscope Image of H5N1 Avian Flu Virus" title="H5N1fluvirus1" width="325" height="210" class="size-full wp-image-5952" /></a><p class="wp-caption-text">Scanning Electron Microscope Image of H5N1 Avian Flu Virus</p></div>In a letter the researchers say, &#8220;This is critical information that advances our understanding of influenza transmission. However, more research is needed to determine how influenza viruses in nature become human pandemic threats, so that they can be contained before they acquire the ability to transmit from human to human, or so that appropriate countermeasures can be deployed if adaptation to humans occurs.&#8221;</p>
<p>But now the perceived fear of the ferret-infected virus escaping from the secure labs is creating a fear pandemic instead. </p>
<p>They continue, &#8220;We would like to assure the public that these experiments have been conducted with appropriate regulatory oversight in secure containment facilities by highly trained and responsible personnel to minimize any risk of accidental release.&#8221;</p>
<p>The scientists agree their research is absolutely necessary to help to public health efforts detect when the H5N1 influenza virus might change in the wild, sparking a human pandemic. But Fouchier of Erasmus Medical College in the Netherlands, Garcia-Sastre of Mount Sinai School of Medicine in New York and Kawaoka of the University of Wisconsin, Madison, the lead authors on the letter in <em>Science </em>and <em>Nature </em>nevertheless are voluntarily suspending it so public perception can catch up.</p>
<blockquote><h3>Censorship in Science</h3>
<p>When a U.S. government advisory panel told the editors of Science and Nature to censor a submitted bird flu paper, the complex issue also enjoined the First Amendment to the U.S. Constitution.</p>
<p>The reason for asking for censorship was noble. Biosecurity experts fear an airborne version of the H5N1 flu virus that becomes transmissible between humans could create a pandemic worse than the 1918-19 outbreak of Spanish flu that killed between 20 million and 40 million people.</p>
<p>The <a href="http://oba.od.nih.gov/biosecurity/about_nsabb.html">National Science Advisory Board for Biosecurity</a> (NSABB) made the following recommendations about the publication of two papers submitted on the highly pathogenic avian influenza, H5N1:</p>
<p>1. Neither manuscript should be published with complete data and experimental details.</p>
<p>2. Conclusions of the manuscripts be published but without experimental details and<br />
mutation data that would enable replication of the experiments.</p>
<p>a) Text should be added describing: 1) the goals of the research, 2) the potential<br />
benefits to public health (including informing surveillance efforts, pandemic<br />
preparedness activities, and countermeasure development and stockpiling efforts), 3)<br />
the risk assessments performed prior to research initiation, 4) the ongoing biosafety<br />
oversight, containment, and occupational health measures, 5) biosecurity practices<br />
and adherence to select agent regulation, and 6) that addressing biosafety, biosecurity,<br />
and occupational health is part of the responsible conduct of all life sciences research.</p>
<p>b) The NSABB should develop a statement that explains their review process and<br />
rationale for the recommendations. This statement will be provided to the journals to<br />
consider for publication.</p>
<p>c) The USG should encourage the authors to submit a special<br />
communication/commentary letter to the journals regarding the dual use research<br />
issue.</p>
<p>In other words, don&#8217;t publish the whole genome and don&#8217;t explain exactly how this mutation occurred.</p>
<p>Both journals responded by agreeing to the recommendations in part.</p>
<p>Science writer <a href="http://blogs.discovermagazine.com/loom/2011/12/20/should-the-new-flu-stay-secret-or-does-secrecy-kill/">Carl Zimmer</a> sums it up best. He describes the journals&#8217; response, &#8220;In essence, “We haven’t decided yet. It would be nice if you let us know how responsible scientists could get hold of the data.&#8221;</p>
<p>Since science is rooted in reproducibility this type of censorship flies in the face of the method. </p>
<p>But the U.S. government does have a history of censoring sensitive science, including the recipe for nuclear fission and fusion. And now the formula for ferret to ferret transmission of bird flu.</p>
<p>Columbia University virologists <a href="http://microbiology.columbia.edu/Poliolab/polio.html">Vincent Racaniello</a> tells Zimmer the censorship move doesn&#8217;t make any sense. He says, &#8220;The point of a science paper is to enable others to duplicate the findings. Are we going to set a new precedent, where security matters override the reason for publication? This is setting a very dangerous precedent for virology and biological sciences in general.&#8221;</p>
<p>But in the end, the scientists themselves agreed to grudgingly redact contested parts of the papers. </p>
<p><a href="http://ec.europa.eu/research/profiles/index_en.cfm?p=1_osterhaus">Albert Osterhaus</a> of Erasmus MC in Rotterdam, the Netherlands says this type of activity is unprecedented. He believes that public health is best served by making the information widely available. A spokesman for Yoshihiro Kawaoka at the University of Wisconsin, Madison also says the lead author will modify the paper and resubmit it. </p>
<p>Meanwhile the editors of <em>Nature </em>and <em>Science </em>are working with government officials to iron out a &#8220;written, transparent plan&#8221; for relevant scientists to have access to the critical details of this research, which will likely not make the published version of the papers. <em>Science </em>editor-in-chief <a href="http://www.aaas.org/news/releases/2011/1220herfst.shtml">Bruce Albers</a>is confident that this all can be resolved in a couple of weeks.</p></blockquote>

			<content:encoded><![CDATA[<p><iframe frameborder="0" scrolling="no" src="http://eplayer.clipsyndicate.com/embed/iframe?windows=1&#038;va_id=3174442&#038;show_title=0&#038;pf_id=1" width="425" height="330"></iframe></p>
<p>For years, scientists have been talking about the era of personalized medicine. While many preparations are underway, the biggest hurdle to widespread adoption has been the prohibitive cost to read a person&#8217;s entire DNA. Our genetic code provides a full road map to preventing and treating disease. We just don&#8217;t know how to read it yet.</p>
<p>Since the first entire human genome was sequenced in 2000, the price and time it takes has tumbled into affordability.</p>
<p>But the entire biotechnology industry has rested on the belief that personalized medicine won&#8217;t work until it takes a day or less to map a whole <a href="http://www.realscience.us/2011/10/27/x-prize-opens-centenarian-genome-competition/">human genome</a> and the cost reaches the $1,000 price point.</p>
<p>Well, 2012 is the year. At this week&#8217;s Consumer Electronics Show in Las Vegas, <a href="http://www.lifetechnologies.com/us/en/home.html">Life Technologies</a> unveiled its latest gadget, a $150,000 high-speed gene sequencer, which allows entire human genome sequencing for $1,000 per genome.</p>
<p>Outfitted with a semiconductor chip instead of tiny microscopes, the Benchtop Ion Proton sequencer is ready to read our DNA fast and cheap. That means this technology will quickly move from the research lab to the doctor&#8217;s office where patients will pay a little more than the $1,000 it costs to sequence a full genome.</p>
<p>There are companies already doing some high-speed, fast-turnaround gene sequencing. But they rely on just pieces of a genome, looking for particular markers to identify risk for specific diseases. No company until now has been able to run a full genome for $1,000 in less than a day.</p>
<p>Life Technologies&#8217; Dr. Robert Bennett says, &#8220;For the first time, you&#8217;ll be able to sequence an entire human genome in a matter of a few hours.&#8221;</p>
<p>Immediately following the announcement, the company said that Baylor College of Medicine, Yale School of Medicine, and The Broad Institute have signed on as the first three customers of the new semiconducting gene sequencer.</p>
<p>Dr. Richard Gibbs, Director of the Human Genome Sequencing Center at Baylor says, &#8220;A genome sequence for $1,000 was a pipe-dream, just a few years ago.&#8221;</p>
<p>Not to be outdone, another company that builds gene sequencers also just announced that its new generation of machine will read an entire genome in less than 24 hours. Illumina hasn&#8217;t announced how much it will cost on a per genome basis.</p>
<p>It&#8217;ll be a year or so before these lightweight machines will begin showing up in doctor&#8217;s offices. But when they do it is still unclear what running a person&#8217;s genome will show.</p>
<p>Doctors must first be trained to use the new technology. The power of personalized medicine and the promise of rapid, inexpensive gene sequencing lies in being able to identify genetic mutations to make medicine more effective, reduce drug interactions, improve preventive health and give the patient more information about his or her health.</p>
<p>But this kind of broad ability could also open up a pandora&#8217;s box of privacy concerns. Namely, how much of a person&#8217;s genetic information should be accessible to insurance companies, which conceivably could discriminate against people with predisposed genetic risks for certain diseases.</p>
<p>Regardless of any controversy, reaching the genome milestone of $1,000 per genome is changing the face of medicine forever. </p>
<p>Richard Lifton, Chair of the Department of Genetics at Yale School of Medicine says, &#8220;The technological advances in the new instrument promise to be game-changing for both research and clinical applications.&#8221;</p>

<p>The first scientific team to sequence the genomes of 100 one-hundred year olds wins $10 million. It&#8217;s the latest offering from the science competition organization, <a href="http://www.xprize.org/">X Prize Foundation</a>, a non-profit designed to spur science and technology by awarding big cash prizes for significant breakthroughs.</p>
<p>Their most famous and first prize was the <a href="http://space.xprize.org/ansari-x-prize">Ansari X Prize</a> which started the commercial race to space.</p>
<p>Now the foundation is challenging biologists to sequence the genetic code of 100 centenarians in an effort to learn something new about longevity. Is there a longevity gene or are these folks just doing the right combination of eating right and exercising to get the most out of their lives?</p>
<p><a href="http://www.einstein.yu.edu/aging/longevity-genes-project.aspx?utm_source=ein-cpr&#038;utm_medium=redirect&#038;utm_campaign=agingproj">Studies </a>of very healthy elderly people show that they don&#8217;t eat a vegetarian diet. They are often obese, smoke and drink and get little exercise. Those who study the healthy elderly find there is something inexplicable that prevents them from getting diseases like Alzheimer&#8217;s and they just don&#8217;t age like other people.</p>
<p>With more people living longer, the new X Prize genomics competition will shed some light on aging and to see if the secret to a long life is written in our DNA.</p>
<p><a href="http://www.bu.edu/alzresearch/team/faculty/perls.html">Dr. Thomas Perls</a>, an Alzheimer&#8217;s researcher at Boston University is the director of the New England Centenarian Study, the largest study of centenarians in the world. He is thrilled that Archon Genomic X Prize is focusing on sequencing the genomes of 100 centenarians.</p>
<p>And he is helping the competition find the one-hundred-plus year olds, drawing from his own study which has a minimum age requirement of 105 to participate.</p>
<p>He says, &#8220;It&#8217;s very hard to get there without some genetic advantages.&#8221;</p>
<p>Noted biologist Craig Venter is co-chairing the Archon Genomics X Prize, which will be judged on accuracy, completeness and the speed and cost of sequencing.</p>
<p>He says, &#8220;We need 10,000 genomes, not 100, to start to understand the link between genetics, disease and wellness.&#8221; This X Prize is merely the first step in revealing the genetic secrets of a long life.</p>
<p><div id="attachment_5349" class="wp-caption alignleft" style="width: 236px"><a href="http://www.realscience.us/blog/wp-content/uploads/2011/10/IrvingKahn.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2011/10/IrvingKahn.jpg" alt="Irving Kahn" title="IrvingKahn" width="226" height="170" class="size-full wp-image-5349" /></a><p class="wp-caption-text">Irving Kahn, oldest living financial analyst</p></div>Irving Kahn will be 106 in December and he says it would be foolish to retire. The investment banker still goes to the office everyday where he enjoys working along side his son and grandson. He reads two financial newspapers every day. He began his career as an investment advisor just before the stock market crashed in 1929.  </p>
<p>In 1978, he began his own firm, which now manages more than $700 million in assets. He adapts to the changing times and now communicates with friends and clients all over the world via the Internet. <a href="http://news.bbc.co.uk/2/hi/business/7804768.stm">BBC News</a> interviewed him about the 2008 financial crisis in 2008.</p>
<p>If you know people like Irving, send them to the <a href="http://genomics.xprize.org/medco-100-over-100">Medco 100 over 100</a>. That&#8217;s the search to find the 100 centenarians to have their genomes sequenced. </p>
<p>These people could hold the secrets to better health for us all, hidden within our own genetic code. This prize could also unleash the era of personalized medicine where health and disease treatment will vary based on a person&#8217;s DNA.</p>
<p>After the healthy centenarians have been selected the teams will race for the $10 million prize, which will be given to the first team that accurately sequences the whole genome of 100 subjects within 30 days for $1,000 or less per genome, at an error rate no greater than one per million base pairs (that&#8217;s 98% accuracy).</p>
<p>The human genome contains more than six billion pairs of <a href="http://en.wikipedia.org/wiki/Nucleotide">nucleotides</a>, the building blocks of DNA. Ultimately, the competition looks to usher in a new era of personalized medicine through sequencing the whole human genome to a level of fidelity never before measured.</p>
<p>Kahn, the oldest living money manager says, &#8220;I&#8217;m at the stage in life where I get a lot of pleasure out of finding a cheap stock.&#8221;</p>
<p>With the new twist on the genomics X Prize, science will begin taking stock of healthy elderly people and study their secret to a long and healthy life.</p>
<blockquote><p><strong>History of the Archon Genomics X Prize</strong><br />
The $10 million Archon Genomics X PRIZE presented by Medco was originally launched in<br />
October 2006, its purse underwritten by a generous donation from Dr. Stewart and Marilyn<br />
Blusson, challenging scientists and engineers to sequence 100 whole human genomes in 10<br />
days or less for less than $10,000 per genome at an unprecedented rate of accuracy.<br />
In the following years, sequencing technology progressed through multiple platforms, carving<br />
out niche research markets, each with its strengths and weaknesses. Teams originally registered<br />
to compete were not yet able to meet the requirements.</p>
<p>In 2010, Grant Campany, who has 20 years of experience in the life sciences industry, signed on<br />
as Senior Director for the Archon Genomics X PRIZE. A new approach to the competition was<br />
developed by Mr. Campany, X PRIZE Foundation leadership and the competition’s Scientific<br />
Advisory Board, including Dr. Venter, X PRIZE Foundation Scientific Advisory Co-Chair, and<br />
one of the first to sequence the human genome in 2000 and create the first cell with a synthetic<br />
genome in 2010. Recognizing that no single technology was serving medical/clinical<br />
requirements, the Archon Genomics X PRIZE presented by Medco was revitalized to be more<br />
inclusive, relevant and robust.</p></blockquote>

<p><a href="http://www.responsibletechnology.org/resources/media-kit/jeffrey-m-smith-bio">Jeffrey Smith</a> has written the book on genetically modified foods (GMOs). Now he&#8217;s on a crusade to rid the U.S. of unhealthy food hybrids that not even animals choose to eat.</p>
<p>He tells the story of a farmer who was growing corn for his cows. The farmer grew non-GMO corn next to corn that had been modified by Monsanto, a large agriculture company. First, he grew the corn independently and then when it was ready for the big cow taste test he separated the corn and gave the cows a choice of which feed they wanted.</p>
<p>He says that without fail the cows chose the regular old non-GMO variety, AKA corn. He says the cows would approach the modified corn and sniff it before walking out of their way to reach the non-GMO corn trough.</p>
<p>Smith believes that if only humans had the sense of cows, we wouldn&#8217;t have any genetically modified ingredients in the food supply. He says, &#8220;It turns out there’s only nine food crops that are genetically engineered but they’re pretty widespread because soy and corn in particular are practically omnipresent in processed foods.&#8221;</p>
<p>Other countries have banned GMOs. Zambia, Venezuela India and all of Europe are GMO-free. But in the U.S. up to 70 percent of processed foods contain one or more genetically modified food ingredients.</p>
<p>What is a GMO?</p>
<p>A <a href="http://en.wikipedia.org/wiki/Genetically_modified_organism">genetically modified organism</a> is an organism that has been genetically altered using engineering techniques. In foods, the most common technique is called <a href="http://en.wikipedia.org/wiki/Recombinant_DNA">recombinant DNA technology</a>, where molecules from different plant species are combined into a single hybrid with a new set of genes. </p>
<p>Some GMOs are <a href="http://en.wikipedia.org/wiki/Transgene">transgenic</a>, meaning that they have intact DNA segments or functional genes from another organism inserted into them.</p>
<p>Food expert <a href="http://elisazied.com/">Elisa Zied</a> is the author of <em><a href="http://nutritionatyourfingertips.com/">Nutrition at Your Fingertips</a></em>. She says, &#8220;If a food is genetically modified it means that its genes are altered. DNA from one species is inserted into DNA of another species to create a unique genetic combination that doesn&#8217;t occur in nature.&#8221; </p>
<p>There are only a handful of crops that have been genetically modified. They include corn, canola, cotton, and soy. However, those are the plants whose derivatives are found in just about all processed foods.</p>
<p>In addition, recombinant bovine growth hormone (rBGH) is commonly injected or fed to cows which then genetically alters the milk they produce. That hormone is often blamed in part for human obesity. After all, the hormone stimulates milk production in cows. Imagine what it does in people. </p>
<h3>Food Fight</h3>
<p>The big fight over GMO foods was fueled by <a href="http://caselaw.lp.findlaw.com/cgi-bin/getcase.pl?navby=case&#038;court=us&#038;vol=447&#038;invol=303">a single Supreme Court ruling in 1980</a>, which allowed companies to patent lifeforms for commercialization.</p>
<p>California company Calgene began selling the the first genetically modified food in 1994. It was the flavrSavr tomato, which was more resistant to rotting than its unaltered version. No special labeling was required and the FDA took a wait and see approach to new gene-modified foods.</p>
<p>Then came insect-resistant cotton and soybeans that could tolerate a potent chemical herbicide, both in 1996. Then thousands of patent applications poured forth starting a GMO frenzy.</p>
<p>According to the Grocery Manufacturers of America in the U.S. by 2009, genetically modified varieties dominated 89 percent of the planted area of soybeans, 83 percent of cotton, and 61 percent of corn.</p>
<p><a href="http://www.i-sis.org.uk/Mae-WanHo.php">Dr. Mae-Wan Ho</a> is a geneticist and biophysicist who runs the Institute for Science in Society. She says, &#8220;Genetic engineering is inherently dangerous, because it greatly expands the scope for horizontal gene transfer and recombination, precisely the processes that create new viruses and bacteria that cause disease epidemics, and trigger cancer in cells.&#8221;</p>
<p>But well-meaning scientists invented genetically modified food crops as a means to common crop problems. GMO plants are resistant to disease and they can tolerate herbicides. They can also become more nutritious when vitamins are added. </p>
<p>However, most anti-GMO activists say the danger far outweighs the benefits and that a worldwide ban on GMO foods must be levied before it&#8217;s too late.</p>
<p>The U.K. Greenpeace website calls GMOs an utter disaster. It says, &#8220;The science of taking genes from one species and inserting them into another was supposed to be a giant leap forward, but instead they pose a serious threat to biodiversity and our own health.&#8221;</p>
<p>The debate rages on and for now GMO is making its way into our grocery stores and our stomachs.</p>
<p>Jeffrey Smith, anti-GMO activist and author of <em><em><a href="http://www.seedsofdeception.com/Public/Home/index.cfm">Seeds of Deception</a></em></em> says, &#8220;I would say 70 to 80 percent of the food sold in the supermarket has some derivative of genetically modified food crops. In addition you have alfalfa, which is used as hay for animals, a little bit of zucchini, crooked neck squash and Hawaiian papaya. There’s also a genetically engineered drug for cows that increases milk supply, but also creates a hormone in the milk that many doctors and scientists think is quite unhealthy.&#8221;</p>
<blockquote><h3>No Laws Against GMO in the U.S.</h3>
<p>Some consumer advocates estimate as many as 30,000 different products on grocery store shelves are contain genetically modified ingredients. That&#8217;s largely because many processed foods contain soy. And, half of North America&#8217;s soy crop is now genetically engineered.</p>
<p>Now, 93 percent of soy, canola oil and cottonseed, 86 percent of corn and 95 percent of sugar beets are genetically modified and they are base ingredients in most of the foods we eat and find in grocery stores.</p>
<p>Smith says just nine food crops have been approved for genetic modification but many others have been affected in the process.</p>
<p><strong>Honey </strong>- Honey can be produced from GM crops. Some Canadian honey comes from bees collecting nectar from GM canola plants. This has shut down exports of Canadian honey to Europe.</p>
<p><strong>Cotton </strong>- Resistant to certain pesticides &#8211; considered a food because the oil can be consumed. The introduction of genetically engineered cotton plants has had an unexpected effect on Chinese agriculture. The so-called Bt cotton plants that produce a chemical that kills the cotton bollworm have not only reduced the incidence of the pest in cotton fields, but also in neighboring fields of corn, soybeans, and other crops.</p>
<p><strong>Rice </strong>- Genetically modified to contain high amounts of Vitamin A. And rice containing human genes is being grown in the U.S. but destined to treat infant diarrhea in the developing world.</p>
<p><strong>Soybean </strong>- Genetically modified to be resistant to herbicides &#8211; Soy foods including, soy beverages, tofu, soy oil, soy flour, lecithin. Other products may include breads, pastries, snack foods, baked products, fried products, edible oil products and special purpose foods.</p>
<p><strong>Tomatoes </strong>- Made for a longer shelf life and to prevent a substance that causes tomatoes to rot and degrade.</p>
<p><strong>Corn </strong>- Resistant to certain pesticides &#8211; Corn oil, flour, sugar or syrup. May include snack foods, baked goods, fried foods, edible oil products, confectionery, special purpose foods, and soft drinks.</p>
<p><strong>Sweet corn</strong> &#8211; genetically modified to produce its own insecticide. Officials from the US Food and Drug Administration (FDA) have said that thousands of tonnes of genetically engineered sweetcorn have made their way into the human food supply chain, even though the GMO crop was approved only for use in animal feed. Monsanto says that about half of the U.S. sweetcorn acreage has been planted with genetically modified seeds.</p>
<p><strong>Canola </strong>- Canola oil. May include edible oil products, fried foods, and baked products, snack foods.</p>
<p><strong>Potatoes </strong>- (Atlantic, Russett Burbank, Russet Norkatah, and Shepody) &#8211; May include snack foods, processed potato products and other processed foods containing potatoes.</p>
<p><strong>Flax </strong>- More and more food products contain flax oil and seed because of their excellent nutritional properties. No genetically modified flax is currently grown. An herbicide-resistant GM flax was introduced in 2001, but was soon taken off the market because European importers refused to buy it.</p>
<p><strong>Papaya </strong>- The first virus resistant papayas were commercially grown in Hawaii in 1999. Transgenic papayas now cover about one thousand hectares, or three quarters of the total Hawaiian papaya crop. Monsanto, donated technology to Tamil Nadu Agricultural University, Coimbatore, for developing a papaya resistant to the ringspot virus in India.</p>
<p><strong>Squash </strong>- (yellow crookneck) &#8211; Some zucchini and yellow crookneck squash are also GM but they are not popular with farmers.</p>
<p><strong>Cotton seed oil</strong> &#8211; Cottonseed oil and linters. Products may include blended vegetable oils, fried foods, baked foods, snack foods, edible oil products, and smallgoods casings.</p>
<p><strong>Meat </strong>- Meat and dairy products usually come from animals that have eaten GM feed.</p>
<p><strong>Sugarbeets </strong>- May include any processed foods containing sugar.</p>
<p><strong>Dairy Products</strong> &#8211; About 22 percent of cows in the U.S. are injected with recombinant (genetically modified) bovine growth hormone (rbGH).</p>
<p><strong>Vitamins </strong>- Vitamin C (ascorbic acid) is often made from corn, vitamin E is usually made from soy. Vitamins A, B2, B6, and B12 may be derived from GMOs as well as vitamin D and vitamin K may have &#8220;carriers&#8221; derived from GM corn sources, such as starch, glucose, and maltodextrin.</p></blockquote>
<p>How can the public make informed decisions about genetically modified (GM) foods when there is so little information about its safety? The short answer is labeling. But efforts thus far to pressure the FDA have fallen short.</p>
<p>According to the FDA and the United States Department of Agriculture (USDA), there are over 50 new plant varieties that have completed all of the federal requirements for commercialization and are waiting to go into production.</p>

			<content:encoded><![CDATA[<p><iframe frameborder="0" scrolling="no" src="http://eplayer.clipsyndicate.com/embed/iframe?windows=1&#038;va_id=2928613&#038;show_title=0&#038;pf_id=1" width="425" height="330"></iframe></p>
<p>Every year about 10-15 people in the U.S. contract the <a href="http://www.dhpe.org/infect/plague.html">plague</a>. Just the sound of the world <em>plague</em> sounds ominous. But the illness is much less of a death sentence than it was during the Dark Ages. Now, a quick dose of antibiotics and the plagued person is right as rain.</p>
<p>After completing the first reconstruction of the plague&#8217;s genome, scientists have discovered why the <a href="http://www.nature.com/nature/journal/vaop/ncurrent/full/nature10549.html">Black Death is just an annoying bug</a> to us now. They discovered that the disease itself hasn&#8217;t changed much in hundreds of years but we have.</p>
<p>After extracting DNA from dried blood in the teeth of Londoners who died from the Black Death which killed nearly half of 14th Century Europe, scientists reconstructed the genome using only skeletal remains.</p>
<p><a href="http://socserv.mcmaster.ca/adna/team-members/kirsten-bos/">Kirsten Bos</a>, a PhD candidate at McMaster University in Ontario played dentist to the plague victims. The anthropologist who specializes in skeletal pathology and infectious disease in past human populations. She then removed 40 teeth from some of the 600 skeletons housed in the Museum of London, drilled into the pulp inside the teeth to extract a black powdery material, which was likely dried blood that contained DNA from the plague bacteria.</p>
<p>And when she was done, Bos returned the teeth, minus a little DNA, to the skeletons at the museum.</p>
<p>While studying the genome of the original Black Death bacteria and the strain commonly found today, the science team discovered astonishing similarity between them. The strain that ravaged Europe, killing 50 million Europeans between 1347 and 1351 and the plague strain today which sickens about 2,000 people each year are almost the same.</p>
<p>Scientists found only a few dozen changes among more than 4 million building blocks of DNA. And they found no discernible reason why the virulent pathogen of yore is so tame today.</p>
<p><a href="http://www.geo.uni-tuebingen.de/arbeitsgruppen/urgeschichte-und-naturwissenschaftliche-archaeologie/mitarbeiter/nach-funktion/detailansicht-nach-funktion.html?tx_wtdirectory_pi1[show]=337&#038;cHash=8d45ac7107b08852a90e8dce86e3d108">Johannes Krause</a> of the University of Tubingen in Germany says, &#8220;They&#8217;re almost identical. Even a mother and a child show more genetic differences than the ancient Black Death strain and modern plague strain.&#8221; </p>
<p>In the intervening years, the bacteria has changed very little while humans have changed a lot. Changes in medical treatment, sanitation and economics put people in a stronger position to fight the plague, which is generally passed from fleas on rodents to people or livestock.</p>
<p>The study authors say that the plague was so deadly because circumstances then were different not because the bacteria was particularly lethal.</p>
<p>Scientists also discovered that by being so devastating the plague essentially changed the human immune system. Study co-author <a href="http://www.anthropology.mcmaster.ca/faculty-1/poinarh">Hendrik Poinar</a> of McMaster University says, &#8220;It changed the human immune system, basically wiping out people who couldn&#8217;t deal with the disease and leaving the stronger to survive.&#8221;</p>
<p><a href="http://www.sanger.ac.uk/research/faculty/jparkhill/">Julian Parkhill</a>, a disease genome expert at the UK Wellcome Trust Sanger Institute wasn&#8217;t involved in the Black Death genome project but has studied the bacteria. He says, &#8220;Getting an effectively complete genome sequence of a bacterium that lived nearly 700 years ago is incredibly exciting.&#8221;</p>
<p><a href="http://www.sdstate.edu/news/articles/chris-chase.cfm">Chris Chase</a>, a veterinarian from South Dakota State University says this research has promise for understanding livestock diseases too. He says, &#8220;I could see that it could have big effects on cattle diseases that have been with us for a long time, pathogens like brucellosis and tuberculosis, and how they have changed under vaccine pressure from their ancestors. That can that help us to design new vaccines.&#8221;</p>
<p>This is the first time a science team has been able to reconstruct an pathogen of this size. Several years ago a team rebuilt the 1918 influenza virus contained in the lungs of frozen Eskimos. The genome of the plague bacterium is much larger than the flu virus.</p>
<p>Genome Sizes:<br />
Black Death &#8212; 4,367,867 base pairs<br />
1918 Flu &#8212; 582,970 base pairs<br />
Human &#8212; 3,000,000,000 base pairs</p>
<blockquote><h3>Base Pair Basics</h3>
<p>In molecular biology and genetics, the linking between two bases on opposite complementary DNA strands that are connected via hydrogen bonds is called a base pair (often abbreviated bp). </p>
<p><a href="http://www.realscience.us/blog/wp-content/uploads/2011/10/helix.png"><img src="http://www.realscience.us/blog/wp-content/uploads/2011/10/helix.png" alt="helix" title="helix" width="183" height="264" class="alignleft size-full wp-image-5273" /></a>In basic Watson-Crick DNA base pairing, adenine (A) forms a base pair with thymine (T) and guanine (G) forms a base pair with cytosine (C). In RNA, thymine is replaced by uracil (U). </p>
<p>Some DNA- or RNA-binding enzymes can recognize specific base pairing patterns that identify particular regulatory regions of genes.</p>
<p>The size of an individual gene or an organism&#8217;s entire genome is often measured in base pairs because the structure of DNA is usually a double helix. Hence, the number of total base pairs is equal to the number of nucleotides in one of the strands (with the exception of non-coding single-stranded regions of telomeres).</p></blockquote>

<p>Seven billion is a big number. It looks like this: 7,000,000,000. According to <a href="http://ngm.nationalgeographic.com/7-billion">National Geographic</a> magazine If you started counting out loud to 7 billion, it would take you 200 years. And, If you took 7 billion steps it would take you around the globe 133 times. </p>
<p>By the end of October, that&#8217;s how many people will inhabit Earth. This symbolic population milestone comes with a list of caveats and some opportunities as well. The lucky 7 billionth planetary citizen will likely be born in India or China, the leaders in global population.</p>
<div id="attachment_5257" class="wp-caption alignright" style="width: 335px"><a href="http://www.realscience.us/blog/wp-content/uploads/2011/10/population2.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2011/10/population2-e1318876831267.jpg" alt="Population" title="population2" width="325" height="209" class="size-full wp-image-5257" /></a><p class="wp-caption-text">We add 80 million people per year as water tables are falling, soil is eroding, glaciers are melting, and fish stocks are vanishing.</p></div>
<p>China is number one with 1.34 billion, followed closely by India with over 1.2 billion while the U.S. is a distant third with 312 million.</p>
<p>However, demographers at the <a href="http://www.unfpa.org/public/">United Nations Population Fund</a> estimate that we are adding 219,000 people to the planet per day, which puts on target to reach 8 billion by 2025 and 10 billion people by 2083.</p>
<p>With all those people and a finite supply of space and resources, there are some challenges that lie ahead. Namely, poverty, access to food and water and a hope for a clean environment.</p>
<p>In Sub-Saharan Africa 900 million people suffer under the double burden of the world&#8217;s highest birthrates and the world&#8217;s deepest poverty. In 40 years that region will house almost 2 billion people, accounting for almost half of the projected growth, according to the New York-based <a href="http://www.popcouncil.org/topics/poppolicy.asp#/Projects">Population Council</a>.</p>
<div id="attachment_5256" class="wp-caption alignleft" style="width: 335px"><a href="http://www.realscience.us/blog/wp-content/uploads/2011/10/population1.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2011/10/population1-e1318877001369.jpg" alt="Population" title="population1" width="325" height="215" class="size-full wp-image-5256" /></a><p class="wp-caption-text">Rural families flock to cities. Now 21 cities have populations larger than ten million. Over 335 cities have more than one million. And only 9 of those cities are in the U.S.</p></div>
<p>John Bongaarts, a spokesman for the research organization tells the Associated Press, &#8220;Most of that growth will be in Africa&#8217;s cities, and in those cities it will almost all be in slums where living conditions are horrible.&#8221;</p>
<p>The <a href="http://www.iwmi.cgiar.org/About_IWMI/Overview.aspx">International Water Management Institute</a> predicts that by 2025 1.8 billion people will live in places from severe water scarcity.</p>
<p>Many African nations are realizing that smaller families are more favorable for food production and access to water.</p>
<p>Lagos, Nigeria is about to overtake Cairo, Egypt as Africa&#8217;s biggest city. There, the former Nigerian health minister says reaching the 7 billion global population number should be a wake up call. He supports formal education for girls, getting teenage girls to stay in school and for women to control the number of children they have.</p>
<p>Babatunde Osotimehin says, &#8220;It&#8217;s an opportunity to bring the issues of population, women&#8217;s rights and family planning back to center stage.&#8221; He says there are over 215 million women worldwide who need family planning but don&#8217;t have access. He adds, &#8220;If we can change that, and these women can take charge of their lives, we&#8217;ll have a better world.&#8221;</p>
<p>But around the world, the challenges of a growing population are different. In Europe population numbers are barely growing and that&#8217;s only because of immigration, which in itself is highly controversial. The death rates in developed countries are outpacing birthrates. But shifting populations from around the world are offsetting those losses and creating steady population growth.</p>
<p>In India, there is a population imbalance. More than half of India&#8217;s population is under 35. This <a href="http://diplomatictitbits.blogspot.com/2010/10/indias-youth-dividend.html">&#8220;youth dividend&#8221;</a> could either be a boon to the Indian economy or it could zap their resources and slow the nation&#8217;s population growth, which by 2025 could be 1.6 billion people, making it the most populous country.</p>
<p>A population demographer in New Delhi says, &#8220;If the young population remains uneducated, unskilled and unemployable, then that dividend would be wasted.&#8221;</p>
<p>India also has a growing gender gap, where boys are outpacing girls in the latest census data. Indian families are showing a preference for sons and because of a surge in sex selection tests, many female fetuses are being aborted.</p>
<p>In China, after decades of forced family planning where urban families are allowed on child and rural families two children, the population growth has slowed rapidly. Perhaps too rapidly. Soon, China will have a shortage of young people to take care of a massive elderly population.</p>
<p>Like India, China has a gender gap. The United Nations says there are 43 million missing Chinese girls because parents restricted to one child opted to abort female fetuses.</p>
<p>In the western world France and the U.S. have the steadiest growth rates, both bolstered by immigration. Italy and Spain are both facing people shortages to help with a rapidly aging population. For the last consecutive four years more people have died in Italy than have been born.</p>
<p>But Lagos, Nigeria is clipping along at a six percent annual population growth. With 15 million and growing in the capital city, Nigeria is Africa&#8217;s most populous country with over 160 million. In Nigeria, 60 percent of the population is under 30 and needs education, training and access to healthcare.</p>
<p>Ndyanabangi Bannet, the U.N. Populations Fund&#8217;s representative in Nigeria says, &#8220;It is a plus if it is taken advantage of but if it is not harnessed, it can be a challenge, because imagine what hordes of unemployed young people can do.&#8221;</p>
<p>A recent article in the journal <a href="http://www.nature.com/nature/journal/vaop/ncurrent/full/nature10452.html">Nature </a>suggests that with drastic changes in agriculture we can accommodate a bigger population. University of Minnesota ecologist Jonathan Foley says there are five key changes we need to make to boost food output and accommodate a bigger global population.<br />
    1. Stop farming in places like tropical rainforests, which have high ecological value and low food output<br />
    2. Improve crop yields in regions of Africa, Latin America, and Eastern Europe where farmland isn&#8217;t meeting its potential<br />
    3. Change farming practices to better manage water, nutrients, and chemicals<br />
    4. Shift diets away from meat<br />
    5. Stop wasting food (up to one-third of all food grown is wasted either in production, transport, or after purchase)</p>
<p>But with 696,000,0000 million able bodies under the age of 30 in India and Nigeria alone, we have the opportunity to change the world for the better before the next 3 billion arrive.</p>

<p>The voice of nature <a href="http://www.davidattenborough.co.uk/biography/">Sir David Attenborough</a> is featured explaining Iceland musician Bjork&#8217;s latest venture &#8212; <em><a href="http://bjork.com/#/news/welcometobiophilia">Biophilia</a></em>. It&#8217;s part music album reflecting the connection points between sound, nature and technology. It&#8217;s an app for iPhones and iPads. It&#8217;s a creation generator for fans of Bjork&#8217;s music to tinker and play with sound to make an instrumental backdrop for the singer&#8217;s powerful a capella voice.</p>
<blockquote><p>…but much of nature is hidden from us, that we can neither see nor touch. Like the one phenomenon that can be said to move us more than any other in our daily lives: sound. Sound, harnessed by human beings, delivered with generosity and emotion, is what we call music. And just as we use music to express parts of us that would otherwise be hidden, so too can we use technology to make visible much of nature’s invisible world. In Biophilia, you will experience how the three come together: nature, music, technology. Listen, learn, and create. &#8212; Sir David Attenborough, intro to <em>Biophilia</em>
</p></blockquote>
<p>This experiment is described as a multimedia exploration mother application, comprising a suite of original music, and interactive, educational and musical artifacts. </p>
<p>The journey begins deep in the cosmos where galaxies form. Fly through homemade constellations that connect to ten songs, each with a different app and activity. The theme song <em>Cosmogony </em>plays as users decide where to begin their experience.</p>
<div id="attachment_5240" class="wp-caption alignleft" style="width: 285px"><a href="http://www.realscience.us/blog/wp-content/uploads/2011/10/BjorkMoon.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2011/10/BjorkMoon-e1318621451863.jpg" alt="BjorkMoon" title="BjorkMoon" width="275" height="206" class="size-full wp-image-5240" /></a><p class="wp-caption-text">Biophilia Project Moon App</p></div>
<p>In <em>Moon</em>, Björk explores the lunar cycles and the effect they have on Earth. The song is based on four different sequences played by four different harpists: Zeena Parkins, Shelley Burgon, Sara Cutler, Carol Emanuel. </p>
<p>About the song, Björk explains, &#8220;With each new moon we complete a cycle and are offered renewal — to take risks, to connect with other people, to love, to give. The symbolism of the moon as the realm of imagination, melancholy, and regeneration is expressed in the song.&#8221;</p>
<p>The sequences of the song repeat, reflecting the lunar cycles.</p>
<p>18-year-old programmer <a href="http://maxweisel.com/blog/about/">Max Weisel</a> designed the Moon app for <em>Biophilia</em>. The song is constructed in 17/8 time measure, a far cry from the musical standard 4/4 time. For that reason the app features a musical sequencer with 17 musical moons. Change the position of each moon to change the note it produces. Anyone can create a new melody each time which can be played with Björk&#8217;s voice.</p>
<div id="attachment_5241" class="wp-caption alignright" style="width: 300px"><a href="http://www.realscience.us/blog/wp-content/uploads/2011/10/BjorkVirus.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2011/10/BjorkVirus-e1318621528189.jpg" alt="Bjork Virus" title="BjorkVirus" width="290" height="193" class="size-full wp-image-5241" /></a><p class="wp-caption-text">Biophilia Virus App</p></div>
<p>In <em>Virus</em>, Bjork tells the love story between a virus and a cell. And of course the virus loves the cell so much that it destroys it. An interactive game in the app challenges the user to halt the attack of the virus, although the result is that the song will stop if the player succeeds. In order to hear the rest of the song, the players will have to let the virus take its course. Taking some artistic license, the cell nuclei will also mouth along to the chorus.</p>
<p>In her song <em>Thunderbolt </em>the Icelandic impresario uses arpeggios, inspired by the time between when lightning is seen and thunder is heard. She also demanded the creation of new instruments in order to properly show the interdependence of nature, innovation and technology. When she debuted Thuderbolt at the Manchester International Festival in June, she used two <a href="http://en.wikipedia.org/wiki/Tesla_coil">Tesla coils</a> as core instruments.</p>
<div id="attachment_5243" class="wp-caption alignleft" style="width: 335px"><a href="http://www.realscience.us/blog/wp-content/uploads/2011/10/BjorkCrystalline.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2011/10/BjorkCrystalline-e1318621637315.jpg" alt="Bjork Crystalline" title="BjorkCrystalline" width="325" height="243" class="size-full wp-image-5243" /></a><p class="wp-caption-text">Biophilia Crystalline App</p></div>
<p><em>Cyrstalline </em>is the lead single on the <em>Biophilia </em>album and it required a new instrument as well. For this Bjork created the <a href="http://trashaudio.com/2011/06/the-gameleste-custom-instrument-commissioned-by-bjork/">gameleste</a>, a hybrid created by combining a gamelan (gong) and a celesta (organ), giving the singer the option of playing the gong remotely like an organ from her iPad. Crystalline tells the story of structure. </p>
<p>Bjork says of the app, &#8220;Travel through tunnels and collect crystals to make your own structure of the song.&#8221; Each move changes the way the song plays as you pick crystals along the way. Different crystals have a different effect, making the song a living, evolving structure. At the end, each play sees the crystal aggregation they have made and can save and share their structure with others.</p>
<p>The song and app explore structural similarities in crystals and music, using them to express changes between closed and open systems and emotional states in an effort to unify the external and internal worlds.</p>
<p><em>Cosmogony </em>embodies the harmony of musical and planetary systems. It’s a song inspired by wonder at the cosmos and the question of how the universe came to be. the app acts as the navigation tool to explore the universe of <em>Biophilia </em>in 3D audio by traveling with your fingertips through space.<div id="attachment_5242" class="wp-caption alignright" style="width: 310px"><a href="http://www.realscience.us/blog/wp-content/uploads/2011/10/BjorkCosmogony.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2011/10/BjorkCosmogony-e1318621733205.jpg" alt="Bjork Cosmogony" title="BjorkCosmogony" width="300" height="243" class="size-full wp-image-5242" /></a><p class="wp-caption-text">Bjork Cosmogony Cover</p></div></p>
<p>The Cosmogony app also alerts users when new apps are available, by highlighting them within the constellations. It exists to expand on the cosmological and unifying aspects of the mother app function and draws on the lyrics of the song which center around creation myths from different cultures. </p>
<p>Laura Sterritt at <a href="http://www.transchordian.com">Transchordian </a>says, &#8220;In this sense, &#8216;mother&#8217; app takes on an additional meaning by relating to the birth of the universe.&#8221; </p>
<p>With her Biophilia project Bjork is embracing technology, collaborating with Apple and National Geographic to break new ground merging music with science to create a new appreciation for both.</p>
<div id="attachment_5239" class="wp-caption alignleft" style="width: 335px"><a href="http://www.realscience.us/blog/wp-content/uploads/2011/10/Bjork.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2011/10/Bjork-e1318621140350.jpg" alt="Bjork Biophilia" title="bjork" width="325" height="182" class="size-full wp-image-5239" /></a><p class="wp-caption-text">Bjork Rocks Science with Biophilia</p></div>
<p>She tells the Guardian she has a three-year educational tour planned, inspired by Biophilia. The paper reports that in addition to the album, the free mother app and its 10 accompanying song apps, the Icelandic singer is mapping out a string of eight six-week residencies, comprising live performances, scientific expositions, and children&#8217;s workshops on nature and music. </p>
<p>Growing up, Bjork says, &#8220;My rock star was David Attenborough&#8221;. Now the rockstar is helping to reinvent the rockstar, herself.</p>
<p>According to Corey Tate at <a href="http://www.thespacelab.tv">Spacelab</a>, &#8220;The Biophilia experience will have central themes of science, earth, and space; it seems to be at the forefront of the new interactive music cool, with the combination of digital music and interactive experiences on the rise.&#8221;</p>
<p>Through 2014, Bjork will visit eight cities around the world, spending a month and a half in each. She will do twice-weekly performances of the album and host scientific exhibitions and classes for students. She says, kids will be able to &#8220;try out the instruments on the iPad and write songs and take them home.&#8221; </p>

<p>A pioneering researcher was awarded the <a href="http://www.nobelprize.org/nobel_prizes/medicine/laureates/2011/press.html#">Nobel Prize in Physiology or Medicine</a> Monday, three days after dying of pancreatic cancer without ever knowing he was about to be honored for his immune system work that he had used to prolong his own life.</p>
<div id="attachment_5189" class="wp-caption alignleft" style="width: 335px"><a href="http://www.realscience.us/blog/wp-content/uploads/2011/10/RalphSteinman.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2011/10/RalphSteinman-e1318281280802.jpg" alt="RalphSteinman" title="RalphSteinman" width="325" height="205" class="size-full wp-image-5189" /></a><p class="wp-caption-text">Ralph Steinman, 1943-2011</p></div>
<p>Cell biologist <a href="http://www.rockefeller.edu/research/faculty/labheads/RalphSteinman/">Ralph Steinman</a> died just three days before he won the coveted science prize. When the announcement was made this morning, the committee held an emergency meeting since Nobel Prizes are given to living scientists. But they decided to award the prize to Dr. Steinman despite his untimely death because the prize was made in good faith while he was still alive. Only the announcement followed his death.</p>
<p>He shares half of the prize with <a href="http://www.scripps.edu/genetics/beutler/">Bruce Beutler</a> who holds joint appointments at University of Texas Southwestern and at University of California San Diego Scripps Research Institute and with <a href="http://www-ibmc.u-strasbg.fr/ridi/profil.php?equipe_id=10&#038;lang=en">Jules Hoffman</a>, a French researcher who is also the form head of the French National Academy of Sciences. </p>
<p>The Canadian-born Steinman made his mark in 1973 when he discovered a new type of cell called the <a href="http://en.wikipedia.org/wiki/Dendritic_cell">dendritic cell</a> that has a unique ability to activate immune cells called T-cells. <div id="attachment_5124" class="wp-caption alignleft" style="width: 291px"><a href="http://www.realscience.us/blog/wp-content/uploads/2011/10/DendriticCell-e1317698269875.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2011/10/DendriticCell-e1317698269875.jpg" alt="Dendritic Cell" title="DendriticCell" width="281" height="281" class="size-full wp-image-5124" /></a><p class="wp-caption-text">Dendritic Cell, discovered by Nobel Prize winner Ralph Steinman</p></div> T-cells are a critical part of the adaptive immune system, sending antibodies or killer cells to destroy invading infections. They also remember an antigen so the immune system can mobilize its defenses faster the next time it comes under similar attack.</p>
<p>Both Drs. Beutler and Hoffman made their contributions in the late 1990s. First, Hoffman studied how fruit flies fight infection in 1996. Two years later Beutler discovered similar findings in mice, demonstrating that flies and mammals activate innate immunity in similar ways when attacked by germs. </p>
<p>Gerold Schuler, head of the department of dermatology at the University Hospital Erlangen in Germany and Steinman’s former post-doc, told The Scientist magazine that Steinman&#8217;s work is worthy of the Nobel Prize. He says Steinman&#8217;s advances, &#8220;are now crucial to understanding and fighting diseases, notably for designing better vaccines.&#8221;</p>
<p>Mouse geneticist Alexander Poltorak at Tufts University says the work that Beutler does is a rare example of exploratory research. While looking for cell receptors for a bacterial byproduct that produces septic shock, Beutler and his team observed that mice with a mutation in a particular gene were resistant to septic shock, a potentially fatal over-stimulation of the immune system.</p>
<p>That gene happened to be quite similar to the Toll gene which Hoffman had discovered in fruit flies a couple years before. </p>
<p>Poltorak, who was the lead author on Beutler&#8217;s groundbreaking <a href="http://www.sciencemag.org/content/282/5396/2085.abstract">1998 <em>Science </em>paper</a> says, &#8220;We didn’t have any hypothesis, and that’s the beauty of it.&#8221;</p>
<p>Since then, scientists have reported about a dozen discoveries of various Toll-like receptors in humans and mice, each of which recognizes certain types of microbial molecules.</p>
<p>This research is important because mutations in any of these receptors can increase the risk of infections or chronic inflammatory diseases like rheumatoid arthritis. </p>

<p>It would be so much easier to replay dreams, record thoughts and communicate without speaking. But this type of futuristic technology was always thought to be a dream of a far away future or the plot of a science fiction movie.</p>
<div id="attachment_5110" class="wp-caption alignleft" style="width: 410px"><a href="http://www.realscience.us/blog/wp-content/uploads/2011/09/MindRecording-e1317317395282.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2011/09/MindRecording-e1317317395282.jpg" alt="Mind Recording" title="MindRecording" width="400" height="200" class="size-full wp-image-5110" /></a><p class="wp-caption-text">Hollywood Movie clip (L), fMRI image of same clip (R)</p></div>
<p>Researchers at University of California Berkeley have figured out how to scan the brain and produce blurry images based on thought patterns. Just as a television image is comprised of pixels, these neuroscientists have discovered that images that begin as thoughts in the brain are composed of 3-D voxels.</p>
<p>The scanning equipment and the playback are definitely in their infancy with each producing crude renditions of what&#8217;s actually happening. But it is a start. Even blurry, somewhat confusing images of thoughts can be useful for interpreting dreams or filling in forgotten thoughts or memories. </p>
<p>But doctors have a much more practical use in mind &#8212; helping stroke patients and others who can&#8217;t communicate by speaking.</p>
<p>Routine use of this technology is decades away. But a brain cap captured the very first image that corresponded to a thought just a couple of years ago. And now we have full pictures of blurry images with a pretty good level of accuracy. With thoughtful focus on this area of neuroscience improving resolution and voxel quality could be just a matter of someone dreaming a little bigger.</p>
<p>Personally, I&#8217;d like to set my DVR to record my dreams so I could watch them back each morning. Wouldn&#8217;t you?</p>
<p>Here&#8217;s the experiment the Berkeley team conducted by reconstructing brain images from YouTube videos and movie trailers.<br />

			<content:encoded><![CDATA[<p><iframe frameborder="0" scrolling="no" src="http://eplayer.clipsyndicate.com/embed/iframe?va_id=2860349&#038;windows=1&#038;show_title=0&#038;pf_id=1738" width="425" height="330"></iframe></p>
<p>It may be the fastest invasion of a slow-moving creature but people in Miami-Dade County are taking care not to mess with the new snail in town. </p>
<p>The east African land snail is making a home in south Florida and causing all sorts of problems. They reproduce at an exponential rate and grow fast. They slime everything they touch, destroy most plants and even eat the stucco off homes to build up their shells. </p>
<p>But the biggest worry for public officials is the health problems the snails pose. They come fully loaded with worms that can pass to humans by just making skin contact with the slow-moving invaders. The worms can get into the brain and cause a type of meningitis that currently has no cure. </p>
<p>So if you are in the south Florida area, steer clear of giant land snails and if you must touch one, use rubber gloves to protect yourself from a serious illness.</p>
<p>Officials are trying to figure out what will best get rid of the invasive pest.</p>
<p>Richard Gaskalla, director of plant industry at the Florida Department of Agriculture and Consumer Services says, &#8220;It&#8217;s us against the snails.&#8221;</p>
<p>Here&#8217;s what you should know about these snails. </p>
<p>They grow to 10 inches long and four inches wide and are considered one of the most damaging land snails in the world. They eat at least 500 species of plants, lay about 1,200 eggs a year, and can carry a strain of non-fatal meningitis. They are prolific breeders and contain both female and male reproductive organs. And the little house-eating buggers can live as long as nine years.</p>
<p>The outbreak started on September 16, when two sisters waved down a fruit fly inspector conducting a routine check in their neighborhood. They told him that the snails were everywhere. Since local and national agriculture inspectors were alerted ten days ago they have removed over 1,000 snails from a one-square-mile area of Coral Gables.</p>
<p>Some older residents remember the last time there was a giant snail invasion in Miami. It was 1966. After a boy brought three snails back from a trip to Hawaii, his grandmother released them in her garden. It took ten years and $1 million to eradicate the slimy pest and is the only known giant African snail eradication program on record.  </p>
<p>Because they are so destructive, the snails are allowed into the U.S. only with special permits and for scientific research. </p>

<p>For years, scientists have been saying that some of the biggest discoveries in science will come from non-scientists. And now that prediction is showing promise as two teams of online video game players have helped solve the structure for an important enzyme found in the HIV virus. </p>
<p>After medical researchers had repeatedly failed to piece together the structure of a class of enzymes called <a href="http://www.ncbi.nlm.nih.gov/pmc/articles/PMC139352/">retroviral proteases</a>,  they turned to the biology video game <a href="http://fold.it/">Foldit</a>, an online puzzle that has users score points by folding proteins and ultimately helping science make key advances like this. The protease enzyme plays a critical role in how the AIDS virus matures and multiplies.</p>
<p>In the hunt for AIDS drugs and a vaccine, scientists are focused on blocking these enzymes but until now they have been stuck, trying to figure out what the molecule looks like.</p>
<p>Foldit was created in 2008 by computer scientists at the <a href="http://www.cs.washington.edu/publications/msb/html/20.2/games.html">University of Washington Center for Game Science</a> in collaboration with biochemist <a href="http://depts.washington.edu/bakerpg/drupal/">David Baker&#8217;s lab</a>.</p>
<p>In the last three years the game has evolved. To piece together the retrovirus enzyme structure, <a href="http://www.cs.washington.edu/homes/scooper/">Seth Cooper</a>, the game&#8217;s co-founder says, &#8220;Gamers used a new alignment Tool for the first time to copy parts of known molecules and test their fit in an incomplete model.&#8221;</p>
<p>The puzzle they were working on was called &#8220;Unsolved Monkey Virus Protein&#8221; and within three weeks two teams had solved the problem, which Dr. Baker then took from the 3-D computer world into the real world.</p>
<p>For the monkey virus problem, Foldit players began with a scientific rough draft of the protease enzyme. During three weeks of play, hundreds of teams and individuals generated over a million structure predictions. And the solution, found by the winning team in 10 days, is nearly perfect. It gives Baker and his colleagues all the information they needed to pinpoint the structure down to almost the last atom. </p>
<p>Postdoctoral researcher Firas Khatib says, &#8220;It&#8217;s the power of citizen science.&#8221;</p>
<p>Before Foldit launched, Dr. Baker&#8217;s lab created a program called <a href="http://boinc.bakerlab.org/">Rosetta@home</a> which allowed computers to run simulated protein folding while the machines sat idle. It worked much like the <a href="http://setiathome.berkeley.edu/">SETI@home</a> screensaver. Instead of searching for extra terrestrial signals from space it ran quick simulations of protein folding. It used distributed processing to crunch massive amounts of data but it was all automated. The user could just sit back and watch the process unfold.</p>
<p>Foldit came into being after some Rosetta users suggested that the computer was making wrong assumptions because it could only follow a logical path. And the solutions to these complex proteins probably required some intuition and exploration, two things a computer can&#8217;t stomach.</p>
<p>Once Dr. Baker&#8217;s lab combined the power of its artificial intelligence with human intelligence he stumbled on a winning combination that could lead to a cure for HIV and other diseases.</p>
<p><a href="http://fold.it/portal/node/985857">Foldit Contenders Group</a> and <a href="http://fold.it/portal/node/548027">Foldit Void Crushers Group</a> are the two teams that received co-authorship on the protease structure paper which was just published in <em><a href="http://www.nature.com/nsmb/journal/vaop/ncurrent/full/nsmb.2119.html">Nature Structural &#038; Molecular Biology</a></em>.</p>
<p>A member from the Foldit Contenders named &#8220;Mimi&#8221; says, &#8220;It is a team thing. Everybody contributes.&#8221;</p>
<p>And that&#8217;s just the motivation Dr. Baker is using to solve the big biological questions. </p>
<p>He says, &#8220;Competitive social interaction is a very strong driving force.&#8221;</p>
<p>Video all about Foldit (By the end you&#8217;ll want to sign up. It&#8217;s infectious.)<br />

<p>Starting in a couple of years you may be able to let out a big sigh of relief that medical diagnostics are moving away from needles and other invasive ways of figuring out what&#8217;s going on in the human body.</p>
<p>New technology that takes detailed readings from our breath are already being tested to determine whether an infection is viral, fungal or bacterial. Heart and cancer patients are also benefiting from such advances.</p>
<p>Even with the proliferation of medical technology in the last decade most patients still have to go to unwieldy machines or send tissue samples collected to labs with similar unwieldy machines. But lab-on-a-chip novel technologies are reducing the size of medical equipment while improving the ability to diagnose with greater accuracy.</p>
<p>In just a few years the advances will make most of the diagnostic equipment handheld. A doctor may have you blow into what looks like a large remote control and then all sorts of information can be gathered by the breath you exhale.</p>
<p>A new non-invasive disease detection facility, developed by the University of Leicester, has just been unveiled.</p>
<p>Students at Leicester University teamed up with researchers from emergency medicine, physics and astronomy, engineering, IT services &#8211; among others &#8211; to pool their knowledge and resources and create the <em>Star Trek</em> inspired unit.</p>
<p>The new facility is designed to detect the “sight, smell and feel” of disease without the use of invasive probes, blood tests, or other time-consuming and uncomfortable procedures.</p>
<p>Scientists from different disciplines worked closely with new technologies and figured out how to use them to examine patients. Their goal was to combine existing diagnostic tools to create a futuristic hospital bed where everything comes to the patient.</p>
<div id="attachment_4935" class="wp-caption alignleft" style="width: 570px"><a href="http://www.realscience.us/blog/wp-content/uploads/2011/09/SickbayInfoGraphic-e1314902614917.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2011/09/SickbayInfoGraphic-e1314902614917.jpg" alt="Leicester Sick Bay" title="SickbayInfoGraphic" width="560" height="298" class="size-full wp-image-4935" /></a><p class="wp-caption-text">Leicester Royal Infirmary&#039;s Star Trek Inspired Sick Bay, courtesy of UKPA</p></div>
<p>The team from the Chemistry department focused on analyzing a patient&#8217;s breath.</p>
<p>Budding astronomers used imaging technology from the Mars rover to search for signs of disease on the surface of a patient&#8217;s body.</p>
<p>A third group peered inside the patient to measure blood flow and oxygenation using engineers and information technology monitors.</p>
<p>Chemistry Professor Paul Monks says that all these different projects were working independently when he and others had a eureka moment, realizing they could combine their efforts.</p>
<p>Dr. Tim Coats, who is a professor of medicine at the university and the head of the accident and emergency department at Leicester&#8217;s Royal Infirmary says the sci-fi inspired sick bay will be used to to diagnose a wide range of diseases from sepsis to bacterial infections and even some cancers.</p>
<p>He says, &#8220;Ultimately in the longer term we would aim to work towards something like the &#8216;tricorder&#8217; device seen in futuristic science series like Star Trek. What we are developing so far is more like a first attempt at the medical bed in the sci-fi series.&#8221;</p>
<p>Already talking to commercial partners, the tricorder team is hoping to move this type of service into hospitals as well as have it available for emergency services in ambulances.</p>
<p>Leicester space scientist Mark Sims co-led the project. He says that years ago doctors would walk up and down the hallways and sniff out disease. Now there are tools to do the sniffing. This project is aiming to connect those technological advances more easily. He says, &#8220;Ten years from now it could be routine for diagnostic technology to be combined in this way.”</p>
<p>But for now, it&#8217;s another sample of science fiction breathing life into science fact.</p>

<p>According to a new study it could take 1,200 years, 300,000 researchers and $364 billion to identify and catalog all the species on Earth.</p>
<p>New research in the online journal <em><a href="http://www.plosbiology.org/article/info%3Adoi%2F10.1371%2Fjournal.pbio.1001127">PLoS Biology</a></em>, a publication of the Public Library of Science uses a new way of calculating just how many plants and animals inhabit Earth. So far of the estimated 8.8 million we have discovered just 1.9 million.</p>
<p>Recent discoveries have been small and weird. They include a <a href="http://www.realscience.us/2008/04/03/new-fish-angles-for-recognition/">psychedelic frogfish</a>, a dime-sized lizard and a blind, hairy lobster found on the ocean floor near Antarctica. Some scientists are actively searching for species to fill in the big gaps on the species pyramid. Others just happen across new species.</p>
<p>Describing the wild world in which we live biologist and study co-author <a href="http://wormlab.biology.dal.ca/">Boris Worm</a> from Dalhousie University in Nova Scotia says, &#8220;We are fairly ignorant of the complexity and colorfulness of this amazing planet.&#8221;</p>
<p>Scientists from the U.S. and Canada who are part of the <a href="http://www.coml.org/">Census of Marine Life</a> released the study this week. It found the previous estimate of global species a bit too difficult to pin down. The range of 3 million to 100 million didn&#8217;t sit well and researchers have been trying to narrow the number.</p>
<p>Using a new computer modeling method Dr. Worm and <a href="http://www.soc.hawaii.edu/mora/Team.html">Camilo Mora</a> from the University of Hawaii now believe the number to be somewhere between 7.5 million and 10.1 million. Even with the more improved method for counting the study admits it could be off by as much as 1.3 million.</p>
<p>In 1758 <a href="http://en.wikipedia.org/wiki/Carl_Linnaeus">Carl Linnaeus</a> built the system that is still used today to name, describe and catalog species. In the 253 years since, about 1.25 million species — roughly 1 million on land and 250,000 in the oceans — have been described and entered into central databases. But there are about 700,000 more species that have yet to reach the central databases. They are sitting in limbo between discovery and classification, many waiting patiently in backroom of major museums like the Smithsonian.</p>
<p>Based on the new way of estimating the number of species on Earth, the biologists estimate there are 6.5 million species found on land and 2.2 million or 25 percent living in the ocean depths. They suggest that about 86 percent of all species on land and 91 percent of those in the seas have yet to be discovered, described and catalogued.</p>
<p>According to the Associated Press, evolutionary biologist <a href="http://www.hedgeslab.org/">Blair Hedges</a> from Penn State University says the new study isn&#8217;t good enough and could be off by millions. He thinks there are many tiny species lurking in corners of the unexplored Earth. And he should know. In 2001 while rooting around in dead leaves in the Dominican Republic in 2001 he found the world&#8217;s smallest lizard, a half-inch long Caribbean gecko. And then in 2008 he discovered a four-inch snake in Barbados that lays a very long egg.</p>
<h3>Who Cares?</h3>
<p>Scientists don&#8217;t want to classify every living creature on Earth just for the sake of saying they did it. They are trying to identify new species which could potentially have benefits for humans, ranging from medicine to climate adaptation.</p>
<p>Famed biologist <a href="http://www.eowilson.org/">E.O. Wilson</a> says undiscovered species need to be found before they disappear taking possible cures with them. He says, &#8220;We won&#8217;t know the benefits to humanity from these species, which potentially are enormous.&#8221;</p>
<p>In order to advance medical and other science he says we need to know what&#8217;s in the environment.</p>
<p>Dr. Mora says, &#8220;Many species may vanish before we even know of their existence, of their unique niche and function in ecosystems, and of their potential contribution to improved human well-being.&#8221;</p>
<p>Lord Robert May, a past president of the British <a href="http://royalsociety.org/">Royal Society</a> praised the new system for estimating species numbers. He says, &#8220;It is a remarkable testament to humanity’s narcissism that we know the number of books in the U.S. Library of Congress on 1 February 2011 was 22,194,656, but cannot tell you — to within an order-of-magnitude — how many distinct species of plants and animals we share our world with.&#8221;</p>
<p>But fledgling projects like the Census of Marine Life and the <a href="http://www.eol.org/">Encyclopedia of Life</a> are trying to speed the process given that human activity appears to be hastening the demise of habitats that could contain undiscovered species.</p>
<p>If the 8.8 million number is right, Erick Mata says, &#8220;Those are brutal numbers.&#8221; The executive director for the Encyclopedia of Life says even with an accelerated rate of discovery, &#8220;We could spend the next 400-500 years trying to document the species that actually inhabit our planet.&#8221;</p>
<h3>Do Something that Counts</h3>
<p>The <a href="http://www.iucn.org/what/tpas/biodiversity/">International Union for Conservation of Nature</a> monitors 59,508 species and classifies 19,625 as somehow threatened. Right now this is the most sophisticated system for monitoring known species and it is only looking at about one percent of the entire list.</p>
<p>That&#8217;s where citizen scientists come in. Scientists believe that some of the yet-to-be-discovered species could be found in our own backyards. </p>
<p>What will you do to help find, describe and catalog species that scientists discover?</p>

<p>The growing garbage problem may have a new solution&#8211;fungus that eats plastic. For years mounting mounds of plastic have been choking landfills and polluting the ocean. Now an annual undergraduate trip to the rain forest may have found a solution to the plastic problem.</p>
<p>Unleashing creativity in science sometimes has amazing results. That&#8217;s what a group of Yale students discovered after they took a trip to the Amazon rainforest in search of fungus that could hold medical or scientific promise. Upon their return they tested the fungus to see if they could detect any biological activity.</p>
<p>One undergrad started the project in 2010 and then graduated. Another 2011 participant in the <a href="https://webspace.yale.edu/rainforest/Site/Home.html">Yale Rainforest Expedition and Laboratory course</a> picked up where she left off and that led to the isolation and discovery of an enzyme in a fungus that helps degrade polyurethane and turns it back into carbon.</p>
<p>Dr. Scott Strobel says, &#8220;The average third grader asks all kinds of great questions; they probe, poke and manipulate. Then somewhere around fourth grade we drive the interest in science right out of these kids. People conclude they can’t do science, but in reality they have been doing science all their lives.&#8221;</p>
<p>He teamed up with Howard Hughes Medical Institute to create the class and create opportunities for students to apply what they learn in the classroom to the real world. HHMI gave a $1 million grant to fund the program for four years.</p>
<p>Yale biochemist Kaury Kucera is a post doctorate researcher who co-leads the annual rainforest trek. She told the <a href="http://www.nhregister.com/articles/2011/08/02/news/new_haven/doc4e38a3be0000b202601933.txt?viewmode=fullstory">New Haven Register</a>, &#8220;We take 15 undergraduates into the Ecuadorean rain forest and collect plant samples.&#8221;</p>
<p>Each year, students collect organisms called <a href="http://plantsciences.montana.edu/facultyorstaff/faculty/strobel/endophytes.html">endophytes </a>found in rainforest plants and then take them back to New Haven to test them for biological activity. The whole program is student-generated so they decide what they want to study. Once back in the lab, students analyze the endophytes that show biological activity to see whether they might have any medical or other practical use.</p>
<p>In 2008 Pria Anand was part of the trip to Ecuador where she gathered plants and later extracted part of a fungus to test its affect on plastic. Her goal was to help reduce the piles that are swelling in landfills, also known as bioremediation. She graduated in 2010 before getting the results she wanted.</p>
<p>Jeffrey Huang in the same class was studying which endophytes were most effective at breaking down chemical bonds.</p>
<p>This year, Jonathan Russell tested one of Huang&#8217;s best endophytes on Anand&#8217;s bioremdiation task. From there Russell focused on locating the enzyme in the fungus that is most effective on breaking down plastic.</p>
<p>All three undergrads are listed as lead authors on the forthcoming paper <a href="http://aem.asm.org/cgi/content/abstract/AEM.00521-11v1?maxtoshow=&#038;hits=10&#038;RESULTFORMAT=&#038;fulltext=polyurethane&#038;searchid=1&#038;FIRSTINDEX=0&#038;resourcetype=HWCIT"><em>Biodegradation of Polyester Polyurethane by Endophytic Fungi</em></a> in the journal <em>Applied and Environmental Microbiology</em>. </p>
<p>This is not the first time a particular agent has broken down polyurethane. But this enzyme can operate in an oxygen-free zone, such as those found underground in landfills.</p>
<p>Since the discovery students in another class are looking at different endophytes to see which if any will be most effective at dissolving polystyrene or styrofoam, one substance that is designed to stick around indefinitely.</p>
<p>Two different Yale students in the 2009 Rainforest Expedition class have had other <a href="http://www.yaledailynews.com/news/2011/jan/26/undergrads-discover-new-fungi-new-biofuel/">fungal breakthroughs</a> which could lead to a new &#8220;myco-diesel&#8221; biofuel and another which could protect agricultural farms from pathogens.</p>

<p>Ultrathin, flexible circuit boards that attach to the skin could replace conventional wired medical equipment, especially when it comes to monitoring vital signs.</p>
<p>New electronic tattoos, also known as epidermal electronics are taking state-of-the-art wireless medical technology and sticking it to a patients&#8217; skin, much in the same way a temporary tattoo is applied.</p>
<p>University of Illinois researcher <a href="http://rogers.matse.illinois.edu/">John Rogers</a> is co-author of the paper which appears in the current issue of <a href="http://www.sciencemag.org/content/333/6044/830">Science</a>. He shows how scientists created s-shaped circuits which can bend and flex with the elasticity of skin.</p>
<p>The thin-skinned electronic medical device can last up to two weeks and in the short term could replace bulky devices that monitor a patient&#8217;s heart rate, blood pressure, brain activity or other vital signs.</p>
<p>In preliminary tests if the tattoo is attached to a video game player&#8217;s throat, muscle contractions in the neck can be translated to allow limited vocabulary in controlling the movement in the game. This can also be used to help people with disorders of the larynx speak again.</p>
<p>Not everyone is hailing this breakthrough in electronics. Some conservative Christian groups are terrified that this scientific advance could also be interpreted as the Mark of the Beast described in the Bible, signaling the end of days.</p>
<p>And at least one bioethicist is already concerned that while voluntary monitoring of someone&#8217;s condition is a good use of this technology, forcing another person to wear an electronic tattoo to see if they are taking their medication or present a security risk is another story altogether.</p>
<p>Northwestern University civil and environmental engineering professor Yongang Huang explains the interest in combining flexible electronics with the human body. He&#8217;s and Dr. Rogers have been working on this technology for six years.<br />

<p>Already heralded as the biggest step in cancer research in decades, a new cancer treatment is forcing conservative doctors and scientists to use words like, &#8220;Amazing.&#8221;</p>
<p>It&#8217;s premature to call this new treatment a cure since it has only been tried in three patients, all of whom have experienced either full remission or seen a significant drop in the number of cancer cells.</p>
<p>The experimental treatment boosts a leukemia patient&#8217;s own immune system by turning infection-fighting T-cells into cancer cell serial killers.</p>
<p>The process involves taking the patient&#8217;s own blood, removing the T-cells and replacing them with a harmless, modified version of the HIV virus. Then the genetically engineered treatment is infused back into the patient where the army of cancer fighters are unleashed on cancer tumors and cells as they form.</p>
<p>For two weeks after the treatment was given to the patients there was no reaction. Then the patients became violently ill, which meant the treatment was working. Reporting the worst flu symptoms of their lives, the patients were flushing all the cancer out of their bodies and it made them sick. </p>
<p>After that episode, two patients remain cancer free one year post-treatment and the third is much improved. All three patients had late-stage leukemia with few other treatment options.</p>
<p>Doctors are cautiously optimistic. They don&#8217;t know how long the genetically engineered cells will remain in the body or if the cancer will return after a certain period of time. But already this treatment is being explored to fight pancreatic, brain and other cancers to see if it has the same results.</p>
<p>Dr. Carl June and a research team at University of Pennsylvania discuss new leukemia cancer treatment using modified HIV virus. (5:26)<br />

<p>Many doctors aren&#8217;t prescribing biotech company Dendreon&#8217;s experimental prostate cancer drug. The company&#8217;s <a href="http://blogs.wsj.com/health/2011/08/04/dendreon-shares-plummet-as-company-withdraws-provenge-sales-forecast/">stock shares dropped sharply</a> after it announced it was firing workers and lowering its revenue forecast for the year. But the drug is hailed as a powerful, yet complicated way to fight cancer.</p>
<p>Two million men live with prostate cancer. Each year another 217,000 men are diagnosed and for 100,000 of them, it is in late stage and spreading. For them, there is little treatment hope. Or was until <a href="http://www.provenge.com/">Provenge </a>came along last year.</p>
<p>It works by teaching the cancer patient&#8217;s own immune system to attack tumors. Provenge has been lauded as an extremely innovative drug and <a href="http://www.dendreon.com/">Dendreon </a>was hailed known as the darling of biotech companies. </p>
<p>Provenge is the first FDA approved prostate cancer immunotherapy treatment. Because prostate cancer cells and hide from or trick immune system T cells, Dendreon has created a unique personalized therapy that uses the patient&#8217;s own natural defenses combined with a unique protein to help immune cells find the cancer cells. </p>
<blockquote><p>&#8220;For years scientists have been attempting to achieve an elusive goal &#8212; to stimulate the body&#8217;s immune system against cancer.&#8221; Dave Urdal, Chief Scientific Officer, Dendreon</p></blockquote>
<p>Doctors seem to be getting sticker shock because Provenge costs $93,000 and until last month <a href="http://www.medpagetoday.com/HematologyOncology/ProstateCancer/27384">Medicare and Medicaid weren&#8217;t reimbursing</a> for it. </p>
<p>According to information on the Provenge website, the drug vaccine teaches the immune system to attack cancer like it would any other non-lethal infection.</p>
<p>The company says it is moving into a big marketing push to get doctors in private practice to begin prescribing the expensive but effective drug. The median life expansion for men using Provenge is 4.1 months. It may not seem like a long survival time but many patients live much longer.</p>

			<content:encoded><![CDATA[<p><iframe frameborder="0" scrolling="no" src="http://eplayer.clipsyndicate.com/cs_api/iframe?windows=1&#038;show_title=0&#038;va_id=2683937&#038;wpid=0" width="425" height="330"></iframe></p>
<p>Gender stereotypes about math and science abound. Boys are known for performing better in math and science while girls tend to excel in history and language arts. Though the U.S. still leads the world in scientific discovery and vision, another stereotype is that the U.S. education system is failing students and allowing other countries to out compete citizens for global jobs.</p>
<p>The results of the six-month long Google Science Fair blew both of those stereotypes right out of the water. Three girls, all from the U.S. won the first annual science competition. They beat out 10,000 other students from 90 countries, demonstrating female and U.S. prominence in science.</p>
<p>But perhaps more notable than breaking stereotypes is the potential real science that these young women are doing. One has discovered a way to make ovarian cancer treatments more effective. Another wants to revise the Clean Air Act using her model, quantifying air pollution among asthmatics. And the third winning project could lead to a barbeque meat marinade that reduces carcinogens.</p>
<p><div id="attachment_4669" class="wp-caption alignleft" style="width: 135px"><a href="http://www.realscience.us/blog/wp-content/uploads/2011/07/ShreeBoseGoogleScienceFairWinner.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2011/07/ShreeBoseGoogleScienceFairWinner.jpg" alt="Shree Bose Google Science Fair Winner" title="ShreeBoseGoogleScienceFairWinner" width="125" height="185" class="size-full wp-image-4669" /></a><p class="wp-caption-text">Shree Bose, Age 17</p></div>A 17 year old from Texas took home the grand prize for developing a way to improve ovarian cancer treatment. Shree Bose has been a curious kid for as long as she can remember. In 3rd Grade, she wanted to help her fellow students appreciate vegetables but thought that the green color is what made the students dislike spinach. She injected a spinach plant with blue food coloring in an effort to make veggies fun. Instead she killed the plant and learned a valuable lesson about science&#8211;perseverance wins the day. Since that first foray into science she is a regular science fair participant who has invented a lighter weight material by combining metal and plastic. And she is a teenage cancer researcher who wants to pursue medical research full-time.</p>
<p>When not in the cancer lab, Bose enjoys a good cattle drive near her home of Fort Worth, Texas.</p>
<p>For her ground-breaking <a href="https://sites.google.com/site/ampkandcisplatinresistance/home">science project</a>, she won $50,000 from Google as well as a trip to the Galapagos Islands on the National Geographic Discovery research ship. She will also have an opportunity to have a once in a lifetime internship experience at CERN, the nuclear physics lab in Switzerland.</p>
<p>Alice Bell, one of the judges for the Google Science Fair and a writer for the UK paper The Guardian says that the teens she met through the judging process are not the public. She says, &#8220;It is perhaps best to think of schoolchildren as holding a liminal position with respect to science and the rest of society. They are not quite inside the scientific community or squarely outside it either. They are both science and &#8216;the public&#8217;, and they are neither of these things, yet. Their lives could go in a range of directions.&#8221;</p>
<p>One thing is for sure, after winning this new scientific accolade, none of these girls lives will ever be the same.</p>

For her award-winning <a href="https://sites.google.com/site/naomibetterairbetterlife/home">science project</a>, she created a mathematical model that quantifies the effects of environmental pollution on people with asthma.</p>
<p>In her project she quotes a common saying among environmentalists, &#8220;The genetic make-up is like loading a gun. The environmental pollutants represent the trigger!&#8221; </p>
<p>Shah noticed that doctors are quick to prescribe steroids and other inhalers, instead of addressing the quality of the air asthma sufferers are breathing. She learned that&#8217;s because nobody had figured out how much air pollution affects lung function. So she did.</p>
<p>Online environmental magazine <em><a href="http://www.grist.org/">Grist </a></em>calls Shah awesome, not because she is a budding scientist but because she &#8220;let&#8217;s her green flag fly.&#8221; Shah describes herself as an environmentalist as well as an objective scientist in training. </p>
<p>She says, &#8220;Air quality doesn&#8217;t get nearly the attention it deserves, and should be one of the top sustainability goals for the coming future.&#8221; </p>
<p>Shah took first place at the Intel Science Fair earlier this year. Since then she has sent President Obama and Environmental Protection Agency Secretary Lisa Jackson a letter asking for her mathematical model to be used to revise the Clean Air Act.</p>

There while she was waiting for her mother, Dallastown, Pennsylvania 14-year-old Lauren Hodge read an article in a magazine about cancer dangers in grilled chicken. After that she watched her mother make grilled chicken and decided to test which marinades block the formation of harmful carcinogens.</p>
<p>She found that lemon juice and brown sugar cut the level of carcinogens sharply, while soy sauce increased them.</p>
<p>Shah and Hodge each received $25000 scholarships and internships at Google and LEGO.</p>
<p>Girl power ruled the day at the first Google Science Fair.</p>
<p>Bose is proud of that fact. She told the New York Times, &#8220;Personally I think that’s amazing, because throughout my entire life, I’ve heard science is a field where men go into.&#8221; She added, &#8220;It just starts to show you that women are stepping up in science, and I’m excited that I was able to represent maybe just a little bit of that.&#8221;</p>
<p>Google science fair judge Vint Cerf was secretly pleased by the female sweep in all three age groups. Of the 15 finalists, there were 9 boys and 6 girls.</p>
<p>Though the competition was completely gender neutral, he says, &#8220;I was secretly very pleased to see that happen. This is just a reminder that women are fully capable of doing same or better quality work than men can.&#8221; </p>

<p>When the final mission of the U.S. space shuttle program blasted off flawlessly on Friday, over one million onlookers gathered in Florida for the launch. Tens of millions more watched on television. But what they couldn&#8217;t see amid the liftoff fire and smoke was <a href="http://www.spaceflight101.com/sts-135-research-experiments.html">all the science</a> that was en route to the International Space Station.</p>
<p>Space Shuttle Atlantis has a lot of experiments, including one from a Hawaiian biotech company called <a href="http://www.tissuegenesis.com/">Tissue Genesis Incorporated</a>. The company has been working with NASA for ten years to study the effects of microgravity on stem cells regenerated from fat tissue.</p>
<p>The research can be applied to fight vascular disease, improve heart bypass surgery and orthopedics.</p>
<p><iframe frameborder="0" scrolling="no" src="http://eplayer.clipsyndicate.com/cs_api/iframe?va_id=2557879&#038;windows=1&#038;show_title=0&#038;wpid=0" width="425" height="330"></iframe></p>
<p>Houston&#8217;s <a href="http://www.odysseysr.com/spacelab/index.html">Odyssey Space Research</a> put two Apple iPhones on the last shuttle mission, not so they can phone home from space but to conduct experiments using mobile applications.</p>
<p>Astronauts will use an app called <a href="http://nanoracks.com/odyssey-launches-spacelab-for-ios-app/">SpaceLab</a>. The experiment app was built to test iPhone cameras and gyroscopes as well as test the effects of radiation on the devices.</p>
<p>Others hope that iPhones will be able to replace some of the expensive and faulty navigation equipment that generally accompanies most space missions.</p>
<p>Besides biotech and high tech companies sending experiments into space the <a href="http://ssep.ncesse.org/">Student Spaceflight Experiments Program</a> has sent a few projects as well.</p>
<p>A mini lab, about the size of a brick contains both professional and student science experiments. The <a href="http://ssep.ncesse.org/current-flight-opportunities/sts-135-final-flight-of-shuttle-atlantis/sts-135-mini-laboratory-operation/">Materials Dispersion Apparatus</a> (MDA) houses about 90 different experiments, including <a href="http://ssep.ncesse.org/2011/05/ssep-is-proud-to-announce-the-student-proposals-selected-for-spaceflight-on-sts-135-the-final-flight-of-the-u-s-space-shuttle-program/">11 student experiments</a>.</p>
<p>Ranging from yeast to tomatoes and from goldfish eggs to mouth bacteria student experiments will study the effects of microgravity by comparing samples on the ground to those that flew into space. Students will look for differences in cell structure, behavior or growth of their samples.</p>
<p>And though it is the last shuttle mission to the ISS, one experiment will perform a white-glove test of the space station to see if it is remaining biological clean after years of use. a state of the art lab on a chip will be able to detect biological and chemicals on any surface.</p>
<p>Another novel experiment comes from Arizona State University, where Cheryl Nickerson is working on developing next generation vaccines. </p>
<p>The microbiologist has been studying infection in microgravity and has already discovered that the salmonella bacteria becomes more virulent in zero-gravity. </p>
<p>She says, &#8220;Our earlier work showed the potential for spaceflight to provide novel insight into the mechanisms of microbial virulence that may lead to innovations in infectious disease control here on Earth.&#8221;</p>
<p>Now Nickerson and her colleague Roy Curtiss III, the director of the Biodesign Institute are hoping to find cures to hepatitis B, tuberculosis, cholera, typhoid fever, AIDS and pneumonia by enlisting the help of salmonella.</p>
<p>When the final flight of Atlantis returns she and Curtiss will examine their <a href="http://asunews.asu.edu/20110706_atlantis_vaccine">Recombinant Attenuated Salmonella Vaccine</a> (RASV) payload to determine if microgravity makes the experimental vaccine that already proves powerful against pneumonia even stronger after going to outer space. </p>

<p>The <a href="http://www.nytimes.com/2011/05/22/us/22snow.html">record snow pack melt</a> combined with cool, heavy spring rains forced reservoirs in northern states to release extra water into rivers, creating a big flood which is now surging south, from North Dakota to Nebraska where the Missouri River is over its banks and threatening two nuclear power plants.</p>
<p><a href="http://www.thebulletin.org/web-edition/columnists/dawn-stover/rising-water-falling-journalism">The Ft. Calhoun plant</a> near Omaha has been offline for maintenance since April, after getting a bad safety report card last year. One of the marks against the plant was lax flood protection, which is now being tested as the Missouri River laps at its front and back doors, leaving part of the facility swamped while the rest stands like a castle surrounded by a moat.</p>
<p>Downriver, the Cooper Nuclear Station has built a ten-foot wall and is still operating normally. That station looks to be adequately protected from the rising flood waters.The <a href="http://www.nrc.gov/homepage/features.html#2">head of the Nuclear Regulatory Commission</a> is visiting the power plant personally to inspect the facility, himself.</p>
<p>A <a href="http://ncrenegade.com/editorial/cooper-nuclear-station-issues-notification-of-unusual-event-and-is-under-a-no-fly-zone/">no-fly zone</a> was imposed over the Ft. Calhoun plant a few days ago but regulators say that no radioactive material has escaped. It was likely imposed to prevent news helicopters from flying too close to the facility and into power lines as they do flood coverage.</p>
<p>In northern New Mexico, it is <a href="http://abcnews.go.com/US/mexico-wildfire-forces-los-alamos-lab-close-residents/story?id=13947824">fire not flooding</a> that has members of the National Nuclear Security Administration&#8217;s Radiological Assistance Program heading for Los Alamos National Laboratory. The team will assess whether any danger exists for radioactive material to escape into the atmosphere from the encroaching 93 square mile wildfire.</p>
<p>As power plants face eminent threats from fire and flood, a year-long investigation by the Associated Press has found that the licensing process at the nation&#8217;s 104 nuclear power plants is not very strict.</p>
<p>Most of the nuclear power plants were built during the 1960s and early 1970s. At the time it was common knowledge that nuclear reactors were built to run for 40 years and then be replaced. That entire life-span was based on the assumption that major upgrades and improvements would be made along the way. </p>
<p>Now the Associated Press is saying that nuclear regulators and the nuclear power industry are rewriting history. The AP says industry and regulators are telling a different story &#8212; that reactor units were built with no expiration date.</p>
<p>This historical about face is making it easier for plant owners to automatically extend the lives of dozens of reactors in a licensing process that amounts to a nuclear rubber stamp.</p>
<p>The AP&#8217;s investigation uncovered documents showing that the process lacks independent safety reviews. It relies on paperwork, especially from NRC, which sometimes matches verbatim language used in the plant operator&#8217;s application. The AP also discovered the relicensing process required very little on-site verification or inspection.</p>
<p>The AP found that 66 of the 104 U.S. reactors have been granted license renewals &#8212; most for an extra 20 years of operation. The NRC has yet to reject a single application.</p>
<p>Regulators say that the 40-year lifespan was chosen for economic reasons and to satisfy antitrust laws not for safety reasons. The AP reports that regulators insist nuclear reactors have no technical limits on their use.</p>
<p>But engineers, including those who designed many of these plants, tell a different story.</p>
<p>In 1982, Clark Gibbs was the chair of an early nuclear industry group&#8217;s safety committee. The AP quotes him, saying, &#8220;Most nuclear power plants, including those operating, under construction or planned for the future, are designed for a duty cycle which corresponds to a 40-year life.&#8221;</p>
<p><a href="http://www.iaea.org">International Atomic Energy Agency</a> Deputy Director General for Nuclear Energy Yury Sokolov told a nuclear industry conference in Shanghai in February that plant life management (PLiM) is a an effective tool to safely and cost effectively manage aging effects in systems, structures, and components. He says, &#8220;Even though the design life of a nuclear power plant is typically for 30 or 40 years, it is quite feasible that many nuclear power plants will be able to operate in excess of their design lives.&#8221; </p>
<p>Last September Germany decided to <a href="http://www.bbc.co.uk/news/world-europe-11194117">extend the life of its aging nuclear power plants</a> by as much as 12 years, even though a poll of Germans found that 6 in 10 want the plants phased out by 2020. Chancellor Angela Merkel says that renewable energy sources are not developed enough yet to get rid of nuclear power.</p>
<p>Then in March, everything changed. When <a href="http://www.realscience.us/2011/03/15/japanese-nuclear-crisis-deepens/">Japan faced a significant nuclear crisis</a> in the wake of the 9.0 earthquake and tsunami that shook the island nation to its core, other nation&#8217;s rattled by what happened in Japan reconsidered their nuclear power position.</p>
<p>Since then, Germany closed seven plants and will <a href="http://www.nytimes.com/2011/05/31/world/europe/31germany.html">phase out all nuclear power plants by 2022</a> Earthquake-prone Chile is considering doing the same and China put 50 power plant applications on hold. But the U.S. is still gung-ho for nuclear power.</p>
<p>In a report from <a href="http://www.scientificamerican.com/article.cfm?id=re-thinking-nuclear-energy">Scientific American</a> last week science investigative journalist Karl Grossman says President Obama embraced nuclear power &#8212; even picking a pro-nuclear Secretary of Energy, Steven Chu &#8212; after initially expressing concerns about its safety while he was running for office in 2007.</p>
<p>Two weeks after the Fukushima Nuclear Power Plant crisis in Japan, President Obama pledged that nuclear power should be revived in the U.S., as it provides “electricity without adding carbon dioxide to the atmosphere.”</p>
<p>Congressman Edward Markey has asked for a <a href="http://blogs.abcnews.com/thenote/2011/03/rep-markey-calls-for-moratorium-on-nuclear-reactor-licenses.html">moratorium on nuclear licenses</a> until new safety standards can be put in place, incorporating the lessons learned in Japan.</p>
<p>Now floods from the north, fires in the southwest and a relaxed relicensing process &#8212; in addition to tornadoes, earthquakes and tsunamis &#8212; threaten the future of nuclear power in this country and our safety. Nuclear power currently provides about 20% of the nation&#8217;s electricity.</p>

<p>For over 30 years the <a href="http://www.fda.gov/">Food and Drug Administration</a> has been wrestling with the rules governing suntan lotion. About five years ago, the federal agency began urging sunscreen companies to give consumers better information about sun protection products.</p>
<p>Now, the FDA is announcing <a href="http://www.fda.gov/Drugs/ResourcesForYou/Consumers/BuyingUsingMedicineSafely/UnderstandingOver-the-CounterMedicines/ucm239463.htm">new rules </a>this week that make deciphering sunblock much easier.</p>
<p>Since it began <a href="http://www.nytimes.com/2010/06/24/fashion/24skinside.html">overseeing sunblock makers</a> the FDA only required companies to protect against ultraviolet (UV) B rays. Those rays cause painful sunburns. But the other UVA rays are the bits of solar radiation that cause skin cancer. </p>
<p>Now, the FDA has created the term &#8220;broad spectrum&#8221; which will begin appearing on sunscreen labels in the next few weeks. Any product that meets the broad spectrum standard is deemed to help block both types of solar rays, UVA and UVB. The FDA is limiting the top Sun Protection Factor (SPF) rating to 50+. </p>
<p>Scientists have not been able to prove that sunblock above SPF 50 protects wearers any better. But the FDA is leaving the door open so if future research finds that SPF 100 is much better at blocking UVA rays than SPF 50 labels may change again.</p>
<p>Most companies knew this change was coming and have begun putting protective information about UVA and UVB rays on packaging for several years. Any sunscreen between SPF 2 and SPF 15 that doesn&#8217;t meet the broad spectrum requirement will get a warning label, saying the product has not been shown to prevent skin cancer or early skin aging. </p>
<p>Many <a href="http://www.dermatology.ucsf.edu/skincancer/General/prevention/Sunscreen.aspx">dermatologists recommend</a> using sunblock with a minimum of SPF 30 to protect from harmful cancer causing UVA rays and painful UVB ray sunburns. They used to recommend a minimum of SPF 15 for extended sun exposure. Now they are suggesting using sunscreens with a higher SPF and to reapply lotions and sprays often.</p>

			<content:encoded><![CDATA[<p><iframe frameborder="0" scrolling="no" src="http://eplayer.clipsyndicate.com/cs_api/iframe?windows=1&#038;show_title=0&#038;wpid=0&#038;va_id=2522494" width="425" height="330"></iframe></p>
<p><em>Update:<br />
Preliminary tests prove negative for E. coli in bean sprouts from an organic farm in the Uelzen district of the German state of Lower Saxony. 23 out of 40 sprout samples from the farm came back negative for the bacteria. 17 samples are undergoing further testing which won&#8217;t be available for 7-10 days.</em></p>
<p>Hamburg, Germany is the epicenter for what is now the deadliest E. Coli outbreak in modern history. 21 people have died and 2,200 people have fallen ill, including over 600 with a <a href="http://www.euro.who.int/en/what-we-do/health-topics/emergencies/international-health-regulations/news2/news/2011/06/ehec-outbreak-update-8">rare disease</a> that causes kidney failure and other dangerous symptoms.</p>
<p>While German health officials haven&#8217;t ruled out tomatoes, cucumbers and lettuce entirely, they are confident that the <a href="http://www.realscience.us/2011/06/02/e-coli-outbreak-strikes-european-veggies/">bacterial outbreak</a> originated in 17 different kinds of bean sprouts on an organic farm. So they took the popular salad item off the menu across the country until further notice.</p>
<p>Bean sprouts are the perfect incubator for E. coli and they have been linked to previous outbreaks, including one in Japan in 1996. According to the Lower Saxony Agriculture Ministry Gert Lindemann, the farm grows 18 types of sprouts and cultivates them in liquor barrels at a temperature of 100 degrees Fahrenheit. Then the sprouts are watered with steam.</p>
<blockquote><p>&#8220;Those are also optimal conditions for the germ of all germs.&#8221; &#8212; Gert Lindemann, Lower Saxony Agriculture Minister</p></blockquote>
<p>U.S. health officials periodically warn people against eating bean and alfalfa sprouts since both are known to carry E. coli.</p>
<p>This strain is new and scientists say it combines the genes of two other strains of E. coli to create a deadly bacteria.</p>

<p>As of Wednesday afternoon officials said 17 people had died in Germany and one in Sweden. A recent E. coli outbreak across Europe is believed to have started in northern Germany but it appears to be causing people to fall ill all around the world, including two cases in the U.S.</p>
<p>The unusually virulent strain of the bacteria commonly found in animal stomachs, including our own, has contaminated fresh vegetables and forced many markets to stop selling cucumbers, tomatoes and lettuce. At first, Germany pointed a finger at cucumbers imported from Spain but later withdrew the accusation. </p>
<p>Officials are worried that they may never know the cause of the food-borne illness, which has sickened over 2,000 people in under a week. </p>
<p>While e. coli bacterial outbreaks occur periodically from poorly handled produce, this outbreak has health officials and scientists more concerned. For one it is striking healthy adults over age 20 and is causing kidney failure, stroke and some patients to lapse into comas. That makes this much more serious than typical outbreaks which cause gastrointestinal distress for most and are more tend to be more serious for the elderly and children. </p>
<p>Scientists immediately ran a gene sequence of the new bacteria and found it is a <a href="http://www.prnewswire.com/news-releases/dna-sequencing-data-reveals-new-hybrid-e-coli-strain-is-cause-of-german-outbreak-123012323.html">new strain of E. coli</a>, which had mutated from two other strains to combine their poisonous effects and become much more deadly.</p>
<p>Hilde Kruse, a food safety expert at the World Health Organization says, &#8220;This is a unique strain that has never been isolated from patients before.&#8221; And she adds, &#8220;Various characteristics that make it more virulent and toxin-producing.&#8221;</p>
<p>According to health experts this outbreak is already the third largest, following a 1996 Japanese outbreak and a 2000 Canadian outbreak. And it may be the deadliest.</p>
<p>The new European E. coli strain shows the presence of genes typically found in two different types of E. coli: enteroaggregative E. coli (EAEC) and enterohemorrhagic E. coli (EHEC).</p>
<p>Because many people likely ate contaminated vegetables but didn&#8217;t have strong reactions, doctors believe the outbreak may be much larger. Those with mild responses to the bacteria probably wouldn&#8217;t seek medical attention. They may stay home from work and recover quickly, thinking they had the flu.</p>
<p>The <a href="http://www.who.int/csr/don/2011_06_02/en/index.html">WHO put information</a> about haemolytic uraemic syndrome (HUS) and enterohemorrhagic E. coli (EHEC) on its website after most people in Germany developed those two diseases from exposure to the bacteria.</p>
<p>A <a href="http://www.euro.who.int/en/what-we-do/health-topics/emergencies/international-health-regulations/news2/news/2011/05/ehec-outbreak-nine-european-countries-report-cases-of-haemolytic-uraemic-syndrome-and-enterohemorrhagic-e.coli-infections">WHO statement</a> says that as of May 31, nine of the patients in Germany had died of HUS and six of EHEC. It goes on to say, &#8220;There are many hospitalized patients, several of them requiring intensive care, including dialysis.&#8221;</p>
<p>NBC News reported that according to doctors, two-thirds of patients in Hamburg, Germany, were suffering from severe neurological problems such as language difficulties and seizures.</p>

<p>For years scientists have argued that <a href="http://www.scientificamerican.com/article.cfm?id=fact-or-fiction-cell-phones-can-cause-brain-cancer">cell phones could be harmful to our health</a>. But it wasn&#8217;t until last year that the <a href="http://oem.bmj.com/content/64/9/626.long">first long term study</a> suggested a relationship between prolonged cell phone use and brain cancer. And even that preliminary finding didn&#8217;t get people to turn off their cell phones.</p>
<p>Earlier this year, a <a href="http://www.realscience.us/2011/02/22/cell-phone-study-finds-increase-in-brain-activity/">National Institutes of Health study</a> showed that cell phones caused an increase in brain activity and glucose metabolism.</p>
<p>Now, a new study from International Agency for Research on Cancer involving <a href="http://monographs.iarc.fr/ENG/Meetings/vol102-participants.pdf">31 researchers</a>(PDF) from 14 countries assembled by the <a href="http://www.iarc.fr/en/media-centre/pr/2011/pdfs/pr208_E.pdf">World Health Organization says that cell phones are carcinogenic</a>(PDF). Actually it says, &#8220;radiofrequency electromagnetic fields are possibly carcinogenic to humans based on an increased risk for glioma, a malignant type of brain cancer, associated with<br />
wireless phone use.&#8221; </p>
<p>The organization puts them in the same category (2B) as gasoline fumes and pesticides. Serious but not that serious if you limit your exposure.</p>
<p><a href="http://www.cedars-sinai.edu/Patients/Programs-and-Services/Cancer-Center/Expert-Team/Neuro-Oncology/Keith-L-Black.aspx">Dr. Keith Black</a>, the head of neurosurgery at Cedars-Sinai Hospital, who was not involved in the study says using a cellphone is about as safe as sticking your head in a microwave oven. He says that the radiation cell phones emit makes water in the brain vibrate. That vibration has the potential to heat up or cook the brain over time just like food in a microwave. And that causes cells to form improperly which leads to cancer.</p>
<p>Right now over 5 billion cell phones are in use around the world. But doctors believe that even if cell phones do pose the cancer risk that long term studies are now beginning to see, brain cancer is a very rare disease. And cell phone use doesn&#8217;t cause cancer it just may increase the risk.</p>
<p>One thing that the scientists do agree upon is that cell phone use by children should be limited to prevent radiation from seeping into their still forming brains. Since children&#8217;s skulls are thinner than adults they can allow in five times as much radiation as an adult brain.</p>
<p>All scientists agree that more research is needed. But since cell phones are so ubiquitous in our lives, it is unlikely that these studies will have a remarkable effect on our cell phone behavior.</p>
<p>For those who are concerned about radiation, limit the amount of time the phone is held to your head. Use a bluetooth or other handsfree device or use the speaker phone function. </p>
<p>University of Washington bioengineering professor <a href="http://depts.washington.edu/bioe/people/core/lai.html">Henry Lai</a> told the L.A. Times &#8220;I think it&#8217;s a very fair conclusion,&#8221; Dr. Lai was the first to show cellphone radiation can damage DNA in brain cells. He and his fellow researchers also found memory loss and other learning problems in rats exposed to moderate levels of cellphone radiation.</p>
<blockquote><p>&#8220;At this point, I think the best thing for people to do is limit their exposure to this radiation.&#8221; &#8212; Henry Lai, University of Washington</p></blockquote>

<p>Cooked tomatoes and tomato products could possibly be more effective than medication in the fight against high cholesterol and blood pressure.</p>
<p>Doctors used to say, &#8220;Take two aspirin and call me in the morning.&#8221; That was the cure all for patients. Now the pharmaceutical companies have a pill for every occasion and ailment. </p>
<p>Researchers in Australia have found that two ounces of tomato paste or tomato juice contains 15 grams of the natural chemical <a href="http://www.cancer.org/Treatment/TreatmentsandSideEffects/ComplementaryandAlternativeMedicine/DietandNutrition/lycopene">lycopene</a>. If people with high cholesterol or high blood pressure consume 50 grams of lycopene it could help lower bad cholesterol levels and blood pressure without the dangerous side effects of cholesterol medications.</p>
<p>Dr. Karin Ried from the University of Adelaide and one of the authors of the paper that appeared in the journal <a href="http://www.maturitas.org/article/S0378-5122%2810%2900446-9/abstract">Mauritas </a>recommends tomato paste. She says that half a liter of tomato juice or 50 grams of tomato paste daily would provide protection against heart disease.</p>
<p>Researchers conducted a meta analysis, meaning they analyzed existing studies, looking at the effects of lycopene on cholesterol and high blood pressure. The scientists analyzed 14 international studies conducted over 55 years.</p>
<p>They found that in small doses, lycopene has little or no effect on reducing cholesterol or blood pressure. But once the amount of lycopene is increased to above 25 grams per day, the authors started to see slight reductions in both cholesterol and blood pressure. They started to see increased benefit with higher amounts of lycopene.</p>
<p>Not everyone is viewing the tomato as the new wonder drug. the website <a href="http://todaysvitalhealth.com/do-tomatoes-really-compare-to-statins/">Todays Vital Health</a> says there have been no direct studies comparing the effectiveness of statins and tomato products in fighting high cholesterol or blood pressure.</p>
<p>Dr. Ried says that lycopene in excess of 25 grams a day can reduce cholesterol and blood pressure by ten percent, eliminating the need for many to take medication, like statins.</p>
<blockquote><p>&#8220;That’s comparable to the effect of low doses of medication commonly prescribed but without side-effects, which can include muscle pain and weakness and nerve damage.&#8221; &#8212; Dr. Karen Ried, University of Adelaide, Australia</p></blockquote>
<p>So just consume 6-8 ounces of tomato products a day and you&#8217;ll keep the need for statins away.</p>

<p>Former Rhode Island Congressman Patrick Kennedy is trying to unite neuroscientists, government and advocacy groups to improve funding and research in brain science.</p>
<p>On the 50th Anniversary of his uncle John&#8217;s moonshot speech that launched the space age, leading scientists, philanthropists and government agencies will call for a new initiative tackling the last frontier of medicine &#8212; the brain and neurological disorders.</p>
<p>But instead of going to outer space he wants us all to go to inner space.</p>
<p>The eight-term Congressman has had very public battles with addiction and depression. Now, the son of Edward Kennedy is putting that attention to good use, trying to shine a light in the dark corners of mental health, traumatic brain injuries and brain diseases.</p>
<p>The <a href="http://www.moonshot.org/">One Mind for Research</a> campaign kicks off with the invitation-only <a href="http://www.onemindnextfrontier.org/?q=content/home">Next Frontier conference</a> later this month. The conference ends on the anniversary of President Kennedy&#8217;s famous speech, which will be celebrated at the JFK Library at Harvard University by Vice President Joe Biden, astronaut Buzz Aldrin and mental health celebrity advocates Glenn Close and Martin Sheetn. </p>
<p>and culminates with the launch of a ten-year, $6 billion program to focus research on the physical causes of mental health and to help cure some of the biggest brain diseases, ranging from Alzheimer&#8217;s and Parkinson&#8217;s disease to depression and post traumatic stress disorder.</p>
<blockquote><p>&#8220;I hear people say that the brain represents the last medical frontier for discovery.&#8221; &#8212; Patrick Kennedy, founder of One Mind for Research.</p></blockquote>

Mary Ann Hitt, Beyond Coal Campaign Director with the <a href="http://www.sierraclub.org/coal/">Sierra Club</a> with information on toxic mercury in fish. Emission from coal-fired  power plants is the leading cause of mercury pollution and subsequent  bio-accumulation in seafood. The heavy metals spew into the air and then  settle in the ocean where they collect in the fatty tissues of our  favorite fish.</p>
<p>The <a href="http://water.epa.gov/scitech/swguidance/fishshellfish/outreach/advice_index.cfm">EPA warns pregnant women</a> or women looking to become pregnant about the dangers of mercury on  unborn children. The agency says stay away from big, predator fish like  Swordfish, Orange Ruffie and even Ahi tuna. They tend to have the  highest mercury concentrations because they feed on smaller fish that  are also exposed to mercury.</p>
<p>But it’s not just women. In men, mercury can increase the risk of heart disease.</p>
<p>Trout, Salmon and other fish, including Tilapia contain far less mercury and won’t pose as much risk to seafood lovers.</p>
<p>The <a href="http://www.sierra.org/mercury">Sierra Club</a> has more information about mercury pollution and finding safe fish to eat.</p>

After a mysterious outbreak of leprosy began a few years ago, researchers began looking for a cause. In a  recent article in the New England Journal of Medicine, scientists  discovered that the armadillo is one of the few animals that carries the bacteria that causes leprosy.</p>
<p>Every year, there are a few cases of leprosy in southern states, where armadillos are as common as squirrels in  urban areas. Just being around the odd-looking creatures is not enough  to acquire the bacteria but those who hunt the animals, handle their raw  meat or eat them could be at higher risk for getting leprosy.</p>
<p>Leprosy experts have known for years that the armadillos carry the leprosy bacteria. In fact, scientists use them to grow the bacteria, which can’t be cultured in the laboratory.</p>
<p>Richard Truman of the National Hansen’s Disease Program in Baton  Rouge, Louisiana led the new study. He used DNA testing to show that a  strain of Mycobacterium leprae not found anywhere else in the world was  present in 28 out of 33 wild armadillos and 25 out of 39 U.S. patients  who lived in areas where the animals lived.</p>
<p><a href="http://www.reuters.com/article/2011/04/27/us-armadillos-leprosy-idUSTRE73Q8IC20110427">Dr.Truman told Reuters</a>, “Around the world, we think of human beings as the only reservoir of Mycobacterium leprae and that leprosy is a human disease.” But now it appears that armadillos are giving the  disease back to humans after first receiving it from people coming to  the New World from Europe and Africa hundreds of years ago.</p>
<p>Researchers think the reason the leprosy bacteria grow in armadillos, but not most other animals, is due to the  armadillos’ lower body temperature of 89 degrees Fahrenheit.</p>

<p>The key to successful <strong>stem</strong> cell research and treatment is being able to create stable, self-renewing <strong>stem</strong> <strong>cells</strong>. For years, scientists have been able to make massive quantities of <strong>stem</strong> <strong>cells</strong> to enhance brain activity. The problem was that when they tested their treatments in mice, the <strong>stem</strong> <strong>cells</strong> often caused tumors to grow, creating a new disease that is much worse than the original.</p>
<p>Now, a team of 30 researchers at University of California San Diego have made groundbreaking advancements in <strong>neural</strong> <strong>stem</strong> cell research which may change the future for patients with vision problems and eventually help those with Parkinson’s disease.</p>
<p><a href="http://eyesite.ucsd.edu/retina/KZL/index.html">Dr. Kang Zhang</a> has been focused on studying eye problems. The ophthalmologist studies  ocular genetics and has a particular interest in stopping macular  degeneration, glaucoma and other diseases of the eye.</p>
<p>Now his team has found a way to slow the progression of macular degeneration using the <a href="http://health.ucsd.edu/news/2011/04-06-geographic-atrophy-ophthalmology.htm">novel <strong>stem</strong> cell treatment</a>.</p>
<p>The self-renewing <strong>stem</strong> cell approach that Dr. Zhang’s team created can grow a very large quantity of <strong>neural</strong> <strong>stem</strong> <strong>cells</strong> without the dire consequences of developing tumors.</p>
<p>While Dr. Zhang is busy creating eye-specific neurons to repair the  ones lost in diseases like macular degeneration he believes his  treatment can be used to fight other neurodegenerative diseases like  Parkinson’s or Lou Gehrig’s Disease.</p>
<p>Not everyone is as enthusiastic about this breakthrough. The <a href="http://www.nctimes.com/app/blogs/wp/?p=12717">North County Times</a> talked to two researchers who recognized this advance as an important  step but reiterated the incremental nature over the breakthrough.</p>
<p>UC Davis cell biologist Paul Knoepfler says, “The fact that [the] group made the <strong>neural</strong> progenitors from human embryonic <strong>stem</strong> <strong>cells</strong> using only a fairly straightforward chemical cocktail should make this  approach one that other researchers in the field can readily replicate.”</p>
<p>Sanford-Burnham Research Institute cell researcher Evan Snyder was less enthusiastic about Dr. Zhang’s development.</p>
<p>He called the research an incremental advance not the big leap forward. He told the newspaper, “The <strong>neural</strong> <strong>stem</strong> cell derivatives are still limited in the range of cell types they can  yield; the authors are still not seeing the full spectrum of  neurectoderm derivatives that they should be seeing — including <strong>neural</strong> crest and glial <strong>cells</strong> (that determine neuron function). He adds, “True <strong>neural</strong> <strong>stem</strong> <strong>cells</strong> should be able to give rise to the range of neurectodermal progeny, including glia and <strong>neural</strong> crest in addition to neurons.</p>

<p>A new report estimates that half the meat and poultry sold in the supermarket may be tainted with the staph germ.</p>
<p>A study published in the journal Clinical Infectious Diseases recently found a startling amount of <a href="http://cid.oxfordjournals.org/content/early/2011/04/14/cid.cir181.full">staphylococcus bacteria in grocery store meat</a>. The study included 136 samples from 80 different brands of turkey, pork, chicken and beef from five cities across the country.</p>
<p>Researchers discovered that 47 percent of all samples contained the staph aureus bacteria, which can make people sick if exposed to it. They also found that of all the samples with staph contamination 96 percent were resistant to one common antibiotic and 52 percent were resistant to three or more antibiotics.</p>
<p>Scientists believe the harmful bacteria in the meat is appearing because animals are being exposed to antibiotic-resistant staph on farms. The bacteria does not appear to be from poor food-handling procedures during manufacturing.</p>
<p>But this study does raise concerns about the use of antibiotics in agriculture. Routinely food farmers give their animals antibiotics to fuel growth rather than to fight disease. Now, it appears decades of feeding drugs to animals is creating a microbial chain reaction that will lead to longer, more intensive human illness when these superbugs become drug-resistant.</p>
<p>Currently, the <a href="http://www.fda.gov/AnimalVeterinary/SafetyHealth/AntimicrobialResistance/NationalAntimicrobialResistanceMonitoringSystem/default.htm">National Antimicrobial Resistance Monitoring System</a> is monitoring four pesky bacteria. NARMS is a collaboration of the Centers for Disease Control, the Food and Drug Administration and the U.S. Department of Agriculture. The group is watching Enterococcus, Salmonella, Campylobacter and E. coli. It doesn&#8217;t currently track staph bacteria or any of its anti-biotic cousins like MRSA.</p>
<blockquote><p>&#8220;Salmonella and Campylobacter, the most common sources of food borne illnesses in the United States, account for well over a million resistant infections in this country each year.&#8221; &#8212; Margaret Mellon, Union of Concerned Scientists, from her <a href="http://www.ucsusa.org/assets/documents/food_and_agriculture/july-2009-pamta-testimony.pdf">Congressional Testimony, July 2009</a>(PDF).</p></blockquote>
<p>Methicillin-resistant staphylococcus aureus (<a href="http://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0004520/">MRSA</a>) has been ravaging patients in hospitals and become a community health problem. Now that this familiar superbug has been found on meat, research needs to be conducted to see if this is part of the reason for the rise of MRSA.</p>
<p>Since heat kills bacteria, cooking meat and cleaning cutting boards, knives or anything (including hands) that comes into contact with raw meat with hot, soapy water should help prevent the spread of staph. Public health officials are watching these tough bacteria closely.</p>
<p>The <a href="http://www.who.int/mediacentre/factsheets/fs194/en/">World Health Organization</a>, <a href="http://www.ucsusa.org/food_and_agriculture/solutions/wise_antibiotics/ucs-urges-congress-to-adopt.html">Union of Concerned Scientists</a> and <a href="http://www.ama-assn.org/ama/pub/news/news/antibiotic-resistance-public-health.page">American Medical Association</a> have called for significant restrictions in the use of antibiotics in animals for non-therapeutic purposes. The <a href="http://www.fda.gov/downloads/AnimalVeterinary/GuidanceComplianceEnforcement/GuidanceforIndustry/UCM216936.pdf">FDA has even drafted guidelines</a>(PDF) advising food farmers to stop giving animals antibiotics that are used as human medicines but until they become regulations they are just suggestions.</p>
<p>In the meantime, drug-resistant bacteria are moving into our food supply.</p>
<blockquote><p>&#8220;Antibiotic-resistant microorganisms generated in the guts of pigs in the Iowa countryside don’t stay on the farm. They can be transmitted to humans in at least three ways: carried on meat or poultry; colonizing farm workers who transmit them into the community; or moving through water and soil, which can lead to the contamination of fresh produce.&#8221; &#8211;Margaret Mellon, Director of the Food and Environment Program, Union of Concerned Scientists</p></blockquote>
<p>Veterinarians say that when antibiotics used in raising food animals such as pigs, cows and chickens are the same as those used in doctors’ offices, those bacteria become impervious to those classes of human drugs.</p>

<p>The radiation levels at Japan&#8217;s Fukushima Dai-ichi nuclear power plant continue to fluctuate. Overnight, the spike in radiation levels forced the remaining workers out of the plant for a short time. Police are planning to use water cannons normally reserved for crowd control to keep nuclear fuel rods submerged in water.</p>
<p>When those rods burn off the water which turns to steam and escapes the compromised reactor container that&#8217;s when radioactive material gets into the atmosphere.</p>
<p>The Fukushima Dai-ichi power plant is not just one nuclear reactor. The whole site is made of six reactors and they all appear to have been damaged after the March 11 9.0 earthquake and tsunami. While the Japanese power plants were built to handle an 8.5 quake and large tsunami this mega quake just dwarfed what the plant can handle.</p>
<p><strong>Timeline of Events</strong><br />
Shortly after the earthquake Japan declared a nuclear emergency when some of the automatic cooling procedures failed. Within hours, power plant workers released low level radioactive steam in an effort to cool the overheating unit 1 reactor.</p>
<p>On March 12, four workers were injured when the built up heat and pressure inside the unit 1 reactor containment building exploded. This hydrogen explosion destroyed part of the outer building but left the nuclear core intact, though compromised and heating up.</p>
<p>Then two days later unit 3 exploded. The outer building was destroyed but the reactor was not breached. Japanese officials reported this explosion as another hydrogen explosion caused by a build up of heat and pressure from the overheating reactor.</p>
<p>In the evening of March 14, officials reported that the unit 2 reactor was intact but that fuel rods had been exposed to air still within the intact containment vessel and therefore not exposed to the outer atmosphere. </p>
<p>Fuel rods are submerged in freshwater to keep them cool. Tokyo Electric Power Company (TEPCO), the company that operates the nuclear power plant says that an airflow gauge was accidentally turned off. When that happens, water can&#8217;t flow into the reactor. As the water boils off from the heat of the fuel rods the rods are left high and dry, which puts them at risk to begin melting.</p>
<p>Then on March 15 a third explosion rocked the Fukushima 1 power station. This time the roof blew off of unit 4, which was believed to have been damaged when unit 3 exploded. </p>
<p>At the same time, radiation spiked from unit 2 where Japanese officials thought the rods had begun melting after the pressure-suppression system was likely damaged.</p>
<p>Later that morning, unit 4 caught fire. Again radiation levels spiked, indicating that nuclear material was escaping into the atmosphere. The International Atomic Energy Agency said the fire was at a spent fuel pond and it took about three hours to extinguish, during which time all remaining nuclear power plant workers were evacuated.</p>
<p>Since then, radiation levels have spiked and dropped. Unit 4 caught fire again. Then unit 3 began emitting what officials believe is radioactive steam from the damaged reactor. Workers planned to spray boric acid from a helicopter on the fuel rods to prevent the spent nuclear fuel rods from reaching criticality again and starting a nuclear chain reaction. But that plan was put on hold because radiation levels near the plant were too high.</p>
<p><strong>Radiation Release</strong><br />
Plutonium, tritium, radioactive iodine, strontium and cesium are all the elements that are being discussed in association with the nuclear crisis at Fukushima Dai-ichi power plant in northeastern Japan.</p>
<p>When the quake struck, reactors 1, 2, and 3 were in service. Units 4, 5, and 6 were undergoing routine maintenance and were already offline. Unit 4 was fully de-fueled, meaning it didn&#8217;t contain a radioactive core. But all six reactors have spent fuel ponds, which became unstable after proper cooling procedures failed after the mammoth quake and resulting tsunami.</p>
<p>First, power plant workers released small amounts of steam containing tritium and cesium to relieve some pressure at unit 1. They did another small release for the same reason at unit 3.</p>
<p>Tritium is an istotope of hydrogen which easily bonds to air and water. It is what is called a low beta emitter, meaning it dangerous externally. Radiation risk only exists if inhaled or ingested in food or water or through absorption through the skin. Tritiated water breaks down in the human body in 7-12 days so therefore poses little risk of short term exposure if ingested and it won&#8217;t accumulate in the body over time.</p>
<p>Cesium is a heavy metal that has 39 different isotopes, ranging from 112 t0 151. Those numbers represent the atomic mass of the element. The most common radioactive isotope is cesium 137. It has a half-life of 30 years, meaning it will take that long to decay into the element barium.</p>
<p>Strontium 90 is another radioactive isotope associated with spent nuclear fuel rods. It is considered a &#8220;bone seeker&#8221; because it exhibits similar biochemical behavior to calcium, the main ingredient in bones. Strontium is generally taken in through contaminated food or water. About 70-80 percent of the strontium is expelled from the body with the rest being absorbed in bone and bone marrow That&#8217;s where concerns about heightened risk of leukemia or bone cancer originate. It&#8217;s half-life is also about 30 years.</p>
<p>With the growing concern about radioactivity leaking into the environment, concerned Japanese citizens and even people on the west coast of the U.S. have flocked to pharmacies to purchase potassium idodide pills to counteract any potential exposure to radioactive idodine. This isotope is 131. It has a half-life of 8 days. </p>
<p>Taking idodine tablets saturates the thyroid gland with iodine just before exposure to prevent radioactive idodine from getting into the gland and causing thyroid cancer. Taking the pills as a precaution is unnecessary if there is no immediate threat of radiation exposure. The pills will only protect people from absorbing idodine 131 for 24 hours.</p>

<p>Scientists studying the brains of dyslexic children say they can now accurately predict which child will overcome their disability and which will continue to struggle to read throughout later life. </p>
<p>A Stanford University research team has been using brain scans on children with dyslexia and they can tell with 90 percent accuracy which kids will overcome the learning disability and which kids will struggle their whole lives.</p>
<p>It&#8217;s not a matter of mind reading but rather of better understanding which areas of the brain are associated with reading. While this personalized treatment isn&#8217;t ready for every child now, perhaps a brain scan of a dyslexic child in the future will help parents decide which course of action to take in helping their child overcome or reduce dyslexia.</p>
<div id="attachment_3993" class="wp-caption aligncenter" style="width: 310px"><a href="http://www.realscience.us/blog/wp-content/uploads/2011/03/brain_dyslexia.png"><img src="http://www.realscience.us/blog/wp-content/uploads/2011/03/brain_dyslexia-300x255.png" alt="" title="brain_dyslexia" width="300" height="255" class="size-medium wp-image-3993" /></a><p class="wp-caption-text"> Brain areas showing greater activation among good readers vs. poor readers </p></div>
<p>Scientists are now convinced there is a marker in the brain that points to an outcome of dyslexia but they aren&#8217;t sure which parts of the brain govern the individual behaviors associated with reading or other cognitive processes like attention or working memory.</p>
<p>In the Stanford study, Fumiko Hoeft found that children who had greater activation in one part of the brain had a better chance to compensate for dyslexia. She also discovered that children with more connectivity between brain regions on the right side of the brain are better able to overcome their deficit.</p>

<p>Stem cells are changing medicine. Every day it seems like there is a new story of a person whose life was spared thanks to advances in stem cell research. </p>
<p>Now, John Christy, a Vietnam veteran, becomes the first person in the U.S. to have his own bone marrow stem cells harvested to save his heart.</p>
<p>He thought he was just getting old and becoming tired more easily. But it turns out that he had advanced coronary artery disease.</p>
<p>Dr. Joseph Woo at the University of Pennsylvania School of Medicine has been testing the use of stem cells in animals for five years and recently used the procedure to grow blood vessels around Christy&#8217;s heart.</p>
<p>Within two days of surgery, Christy says he had &#8220;more oomph.&#8221;</p>
<p>Dr. Woo does this transplant in one short surgery, compared to two surgeries weeks apart in Europe.</p>

<p>The device, about the size of a desk telephone, is the world’s smallest cancer diagnostic system, according to the scientists. </p>
<p>The system uses antibodies and nano-sized magnetic particles to seek out and flag cancer in cells, which are extracted with a needle, rather than large amounts of surgically removed tissue commonly used in traditional biopsies.</p>
<p>Until results from a pre-clinical trial were published this week in the journal <a href="http://stm.sciencemag.org/content/3/71/71ra16.abstract">Science Translational Medicine</a> some scientists were skeptical of this new tool.</p>
<p>The scanner attaches to a smartphone with a special software application, showing if tumor cells are cancerous or not in about an hour.</p>
<p>The new technology is about 96 percent effective, far more than the 84 percent accuracy rate of a skin biopsy. Further testing is needed before this $200 device hits the market.</p>
<blockquote><p>&#8220;It&#8217;s an important tool to allow us to start asking questions we previously couldn&#8217;t,&#8221; &#8212; Cesar Castro, oncologist at Massachusetts General Hospital and co-author of the study</p></blockquote>

<p>The conversation was sparked by this weekend&#8217;s <a href="http://www.aaas.org">American Association for the Advancement of Science</a> conference in Washington D.C. where top scientists gathered to discuss breakthroughs, discoveries and science policy.</p>
<p>Food shortages, rapid population growth and a more affluent developing world all spell resource shortages in the future. That will dramatically change the face of the planet. And scientists are starting to discuss how we can prepare now.</p>

<p>From the front line of the food wars comes a new warning for those who regularly consume beverages and condiments that contain caramel coloring.</p>
<p>The Center for Science in the Public Interest is asking the FDA to ban all food products with an artificially dark color, including Coke, Pepsi and other cola drinks, Worcestershire sauce, whiskey and some dark beers.</p>
<p>Caramel coloring doesn&#8217;t add anything to the foods except&#8230;color. It&#8217;s not a preservative and it adds no nutritional value. The caramel coloring that concerns some scientists breaks down sugars using ammonia and in some cases cancer-causing chemicals get released during the reaction.</p>
<p>That has some scientists concerned. But others say that in order to get a cumulative effect of the tiny amounts of carcinogenic chemicals, you would need to drink 10,000 Coca-Colas a day for a lifetime.</p>
<p>Nevertheless the state of California is considering putting warning labels on Coke and other products containing caramel coloring. The beverage industry says there is no cancer-causing agents in any of its products.</p>
<p>Even if the risk is minimal, CSPI says take the color out and you remove the problem. </p>

<p>It sounds backwards; HIV cure leads to treatment. Shouldn&#8217;t it be the other way around? In this case, an accidental cure in one man of the debilitating autoimmune disease has given new hope to a new genetically-engineered treatment. </p>
<p><a href="http://www.sangamo.com/index.php">Sangamo Biosciences Inc.</a> is developing a new form of gene therapy driven by the case of patient Timothy Brown who may be the only person that&#8217;s ever been cured of AIDS. </p>
<p>Brown received a stem-cell transplant in Berlin in 2007 that transferred genetic material to him from one of the 2 percent of people with natural immunity to HIV, Bloomberg Businessweek reports in its<a href="http://www.businessweek.com/magazine/content/11_08/b4216018308281.htm"> Feb. 14 issue</a>. </p>
<p>He’s been off treatment since then, and no trace of the AIDS virus has been found in his body, according to Brown&#8217;s hematologist. </p>
<p>Here&#8217;s Timothy Brown&#8217;s story:<br />

<p>Microsoft co-founder Bill Gates is increasing his foundation&#8217;s commitment to eradicating Polio. At last week&#8217;s World Economic Forum meeting in Davos, Switzerland, <a href="http://blogs.nature.com/news/thegreatbeyond/2011/01/gates_uk_government_pledge_to.html">Gates pledged $100 million</a> to a global effort that appears close to eliminating the disease. Gates joins Rotary International&#8217;s <a href="http://www.rotary.org/en/EndPolio/Pages/ridefault.aspx">End Polio</a> campaign which has raised over $1 billion from members to fight the crippling disease.</p>
<p>Right now polio is endemic in only four countries&#8211;Afghanistan, Pakistan, India and Nigeria. With the successful elimination of smallpox as a measuring stick British Prime Minister David Cameron says that polio will be the next disease to be eradicated but &#8220;we just need to finish the job.&#8221;</p>
<p>The additional Gates Foundation funds are part of a <a href="http://www.gavialliance.org/">$10 billion, 10-year vaccine initiative</a> aimed at improving health conditions in developing countries. </p>

<p>In Jeopardy&#8217;s! 47 year history, there has NEVER been a contestant like Watson. And who knew the first public face-off between man and machine would be a TV game show. </p>
<p>Jeopardy champions Ken Jennings and Brad Rutter represented humanity in a demonstration of intellectual prowess against a new IBM supercomputer named Watson.</p>
<p>Both seasoned human contestants say playing against Watson is like playing against a really tough competitor but it can be beat both on the buzzer and in answering the question.</p>
<p>IBM unveiled Watson, which is the size of ten refrigerators, not to beat Jeopardy champions but to demonstrate that it has the ability to take information from atlases, encyclopedias and other reference works and not just regurgitate facts. Watson has the ability to contextualize by taking all surrounding facts about a place, person or process and arrive at a likely conclusion based on the information presented.</p>
<p>The company is hopeful that this new generation of supercomputer will speed medical diagnoses and perform other useful real world computation in a fraction of the time.</p>
<blockquote><p>&#8220;I don&#8217;t know if there is a Vegas [betting] line, but always bet on humanity.&#8221; &#8212; Jeopardy champion Ken Jennings</p></blockquote>

Making Her research on a chemistry method called Systematic Evolution of Ligands by Exponential Enrichment (SELEX) come alive through an interpretive dance, scientist and dancer Maureen McKeague from Carelton Unviersity in Ottawa, Canada took home the top prize last fall. </p>
<p>Her dance, titled &#8220;Selection of a DNA aptamer for homocysteine using systematic evolution of ligands by exponential enrichment&#8221; doesn&#8217;t sound like something that could be easily translated for a non-scientist let alone set to the music of Lady Gaga, among others.</p>
<p>The target is a small molecule called <a href="http://en.wikipedia.org/wiki/Homocysteine">homocysteine</a>, the main dancer with a target painted on her shirt. (That&#8217;s Maureen McKeague.) SELEX is a chemical technique that creates short RNA and DNA segments called aptamers (the other dancers). Aptamers are nucleic acids that can be designed to stick to any molecule&#8211;in this case the amino acid homocysteine. <em>Watch for the Taq Polymerase scene in the middle of the dance. </em> High levels of homocysteine in blood is associated with heart disease.</p>
<p>Dr. McKeague&#8217;s work aims to use the SELEX process to make aptamers to easily and cheaply measure homocysteine levels in blood samples. She and the 12 students in <a href="http://http-server.carleton.ca/~mderosa/index.html">Maria DeRosa&#8217;s</a> bionanotechnology research group helped give McKeague her win, which was announced in a special event in New York in October.</p>
<p>45 Ph.D. students entered the 2010 Dance Your Ph.D. contest. McKeague won with 69 percent of the online vote. You can view all the finalists <a href="http://gonzolabs.org/dance/videos/">here</a>.</p>

<p>A new blood test is so sensitive that it can spot a single cancer cell lurking among a billion healthy ones. This breakthrough in cancer diagnostics is moving one step closer to being available at your doctor&#8217;s office. </p>
<p>Right now, this test is being used with cancer patients who would otherwise have to wait months to see if a treatment is working. The current method of using CT scans requires a lot of time. The blood test which is being tested by a subsidiary of Johnson &#038; Johnson will tell doctors with a simple blood test if their prescribed treatment is working.</p>
<p>Down the road this type of test shows some promise in helping to identify cancer much earlier than current tests, such as mammograms and colonoscopies.</p>

<p>British and American botanists announced last week that they have created a list of all known land plant species, containing 1.25 million scientific names. This two-year project has created the largest and most comprehensive <a href="http://www.theplantlist.org">plant list</a> ever made.</p>
<p>The goal is to have all plants cataloged and identified so scientists and others will have the ability to plan the sustainable use of plants, which are essential resources for food, medicines, and ecosystem services. The primary reason for the plant list is to ensure easy botanic retrieval of information about plants.</p>

			<content:encoded><![CDATA[<p>On the last day of 2010, the final day of the last year in the first decade of the 21st Century, we bid farewell to another year. Let&#8217;s take a look back over the last 12 months through the eyes of science.</p>
<p>First, physicist Dr. Michio Kaku looks back over the natural disasters that rocked the world and does some future disaster forecasting as well.</p>
<p><img style="visibility:hidden;width:0px;height:0px;" border=0 width=0 height=0 src="http://c.gigcount.com/wildfire/IMP/CXNID=2000002.0NXC/bT*xJmx*PTEyOTM4NDA*NjM*ODEmcHQ9MTI5Mzg*MDQ2ODUyOCZwPTEyNTg*MTEmZD1BQkNOZXdzX1NGUF9Mb2NrZV9FbWJlZCZn/PTMmbz*xMzI*YmM4NTBkOTM*MWVhYjU3ZDcwNzhmNDk*OTUxOCZvZj*w.gif" /><object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,124,0" width="344" height="278" id="ABCESNWID"><param name="movie" value="http://abcnews.go.com/assets/player/walt2.6/flash/SFP_Walt_2_65.swf" /><param name="quality" value="high" /><param name="allowScriptAccess" value="always" /><param name="allowNetworking" value="all" /><param name="flashvars" value="configUrl=http://abcnews.go.com/video/sfp/embedPlayerConfig&#038;configId=406732&#038;clipId=12506831&#038;showId=12506831&#038;gig_lt=1293840463481&#038;gig_pt=1293840468528&#038;gig_g=3" /><param name="allowfullscreen" value="true" /><embed src="http://abcnews.go.com/assets/player/walt2.6/flash/SFP_Walt_2_65.swf" quality="high" allowScriptAccess="always" allowNetworking="all" allowfullscreen="true" pluginspage="http://www.adobe.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFlash" type="application/x-shockwave-flash" width="344" height="278" flashvars="configUrl=http://abcnews.go.com/video/sfp/embedPlayerConfig&#038;configId=406732&#038;clipId=12506831&#038;showId=12506831&#038;gig_lt=1293840463481&#038;gig_pt=1293840468528&#038;gig_g=3" name="ABCESNWID"></embed></object></p>
<p>2010 started with a major earthquake that killed 200,000 and 3 million homeless in Haiti. Then later in the year a gigantic quake in Chile knocked the Earth off its axis and shortened our 24-hour day by one micro-second. Dr. Kaku insists that the planet is not trying to seek revenge on the human species, which has also been very busy this year.</p>
<p><strong>Top Bio Stories</strong></p>
<p>According to <em>Genetic Engineering &#038; Biotechnology News</em> 2010 was a big year for biology. Last year third-generation gene sequencers came to market which opened the door to generate DNA sequences as well as epigenetic information with single-molecule sensitivity in real time. This was also the year that synthetic biology became mainstream. J. Craig Venter created a bacteria from scratch, making <a href="http://inventorspot.com/articles/new_era_science_synthia_first_synthetic_life_created_42200">Synthia </a>the first fully synthetic, self-replicating cell.</p>
<p>2010 Also saw the gene patent wars heat up. In the Spring a New York <a href="http://www.genomicslawreport.com/index.php/2010/03/30/pigs-fly-federal-court-invalidates-myriads-patent-claims/">court declared</a> the patent on the breast cancer genes BRCA1 and 2 invalid. This case will likely end up before the U.S. Supreme Court before it&#8217;s finished but the Justice Department now supports the lower court&#8217;s ruling, saying that naturally occurring phenomena such as genes should not be subject to intellectual property laws.</p>
<p>Stem cells, aging and cancer rounded out a full year for biotech. After President Obama repealed former President Bush&#8217;s ban on research involving embryonic stem cells this year a <a href="http://www.nytimes.com/2010/08/24/health/policy/24stem.html">federal court judge</a> placed the future of embryonic stem cell research in limbo again. </p>
<p>After all the excitement about the anti-aging benefits of <a href="http://www.sirtuins.com/life-extension.html">sirtuins</a>, the chemical found in red wine, is still not well understood. A couple of drug candidates involving the activator and inhibitor are in clinical trials but haven&#8217;t made the medical strides they promised last year.</p>
<p>A cancer vaccine called <a href="http://www.dendreon.com/products/provenge/">Provenge </a>made it to market this year to help treat prostate cancer. Several other treatments are in late stage clinical trials and could be ready next year.</p>
<p><strong>Top Physics and Space stories</strong></p>
<p>One of the most inspiring space endeavors to finish a rocky trip in 2010 was the Japanese <a href="http://www.isas.jaxa.jp/e/enterp/missions/hayabusa/index.shtml">Hayabusa mission</a>. It rendezvoused with asteroid Itokawa in 2005 after being pummeled by a large solar flare in 2003. The goal was to gather dust from the asteroid and bring it back to Earth.</p>
<p>After all the technical mishaps Japanese researchers didn&#8217;t hold much faith that the probe would return with any dust. But after a triumphant return to Earth in June, a few specks of the asteroid were identified. Now scientists have another tool to understand the beginnings of our solar system.</p>
<p>But 2010 was all about space water. Remember water on Mars? That was so last year. This year confirmed <a href="http://www.reuters.com/article/idUSTRE65D61N20100615">water on the moon</a> and on one of Saturn&#8217;s moons.</p>
<div id="attachment_3722" class="wp-caption aligncenter" style="width: 335px"><a href="http://www.realscience.us/blog/wp-content/uploads/2010/12/Enceladus1-e1293835914845.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2010/12/Enceladus1-e1293835914845.jpg" alt="" title="Enceladus1" width="325" height="291" class="size-full wp-image-3722" /></a><p class="wp-caption-text">Saturn's Moon Enceladus, as viewed from NASA's Cassini Spacecraft</p></div>
<p>The ever-impressive NASA Cassini Equinox mission continues to blow us away with amazing imagery from the Saturnian system, including what appears to be liquid water shooting from the south pole of Saturn&#8217;s moon Enceladus. The spacecraft has been orbiting the ringed gas giant since 2004, buzzing past its many moons and delivering some of the most detailed observations of this iconic planet we have ever seen.</p>
<p>But closer to home, NASA&#8217;s Lunar Reconnaissance Orbiter found that the moon not only has water ice stored in the shadows of its deepest and darkest craters, but there appears to be a lot of water just below the surface.</p>
<p><em>Discovery News</em> asks how much water is there. </p>
<p>Writer Ian O&#8217;Neill says, &#8220;Bucketloads. 600 million gallons stashed away in 40 craters as measured by a NASA instrument that flew on board the Indian Chandrayaan-1 mission. But how much water is 600 million gallons? That&#8217;s enough water to fulfill Seattle&#8217;s water needs for a whole year&#8230; or enough water to manufacture 588 billion bags of Cool Ranch Doritos (according to one commenter who obviously has way too much time on his hands).&#8221;</p>
<div id="attachment_3723" class="wp-caption aligncenter" style="width: 335px"><a href="http://www.realscience.us/blog/wp-content/uploads/2010/12/moonwater.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2010/12/moonwater-e1293836089137.jpg" alt="" title="moonwater" width="325" height="273" class="size-full wp-image-3723" /></a><p class="wp-caption-text">(Artist rendering of moon landing...not a real picture)</p></div>
<p>2010 was the year that President Obama canceled the Constellation manned space program and scrapped plans to go to the moon. But it was also the year that commercial space flight became a reality. Leading the way into space is Virgin Galactic. SpaceX and Orbital Sciences are helping to privatize the space industry and will be fulfilling space services for NASA once the shuttle program is retired in early 2011.</p>
<p>But the biggest space story of the year was happening right here on Earth. Or rather under the Earth at the European nuclear science lab CERN. There particle physicists in search of the elusive Higgs Boson or God particle have successfully trapped antimatter for the first time.</p>
<div id="attachment_3724" class="wp-caption aligncenter" style="width: 330px"><a href="http://www.realscience.us/blog/wp-content/uploads/2010/12/antihydrogen1.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2010/12/antihydrogen1.jpg" alt="" title="antihydrogen1" width="320" height="253" class="size-full wp-image-3724" /></a><p class="wp-caption-text">Physicists capture antihydrogen for the first time in 2010</p></div>
<p>Capturing antihydrogen will allow physicists to study the beginning of the universe and try to figure out why if both matter and antimatter were created in equal amounts during the Big Bang that matter is all that mattered for its formation.</p>
<p><strong>Top Stories by Accident</strong></p>
<p>Science makes some its greatest discoveries through accidental encounters and without looking. A few stories found their way to us that way this year, mostly from the animal kingdom.</p>
<p>The most distressing story resulted from pictures of oil covered seabirds struggling in the slimy Gulf of Mexico after the BP Horizon Deepwater oil rig explosion and disaster. Months later, clean up efforts are still underway and scientists are looking at long term consequences of the largest oil spill in U.S. history.</p>
<p>But across the world, a two-foot long isopod &#8212; that looks like something Hollywood cooked up for a sci-fi movie &#8212; hitched a ride to the surface aboard a deep sea submarine, giving the world a glimpse of this rare giant creature.</p>
<div id="attachment_3717" class="wp-caption aligncenter" style="width: 335px"><a href="http://www.realscience.us/blog/wp-content/uploads/2010/12/giantisopod-e1293834157482.jpg"><img src="http://www.realscience.us/blog/wp-content/uploads/2010/12/giantisopod-e1293834157482.jpg" alt="" title="giantisopod" width="325" height="243" class="size-full wp-image-3717" /></a><p class="wp-caption-text">Deep Ocean Submarine Finds Giant Hitchiking Isopod</p></div>

<p>A man is cured, doctors are stunned and patients have new hope. It could be the cure for HIV. It worked on <a href="http://www.reuters.com/article/idUSTRE6BE68220101215">one man in Germany</a> and now a San Francisco company is trying to do replicate the results in the United States. </p>
<p>&#8220;We have this patient in Berlin who develops leukemia, gets a bone marrow transplant from donor who has a genetic anomaly, he lacks CCR5 genes. It turns out CCR5 is the key doorway for HIV to get into the cell,&#8221; explains <a href="http://www.questclinical.com/about.html">Quest Research&#8217;s</a> Dr. Jacob Lalezari. </p>
<p>Now, four years later with no other treatment that patient is HIV free. The goal now is to replicate what happened in Berlin. </p>
<p>Doctors in Germany gave a patient a bone marrow transplant in 2007 to treat leukemia. The patient also was HIV-positive so doctors selected a donor known to have a specific <a href="http://www.hivgene.com/what-is-ccr5.php">gene mutation</a>, known for blocking HIV from entering cells.</p>
<p>The risky transplant involves killing off a patient&#8217;s unhealthy bone marrow and all the white blood cells, leaving the patient without an immune system until doctors infuse donated stem cells to rebuild the bone marrow which can then produce healthy cells. </p>
<p>Because the stem cells that were introduced in an HIV-postive U.S. man in his 40s contained the HIV-blocking mutation, the healthy cells became resistant to HIV and wiped out the virus in the process.</p>
<p>Scientists have discovered it&#8217;s relatively easy to remove HIV from the bloodstream but it tends to lurk in the brain, gut and lymphatic tissue.</p>
<p>This breakthrough has eradicated the virus from the patient&#8217;s entire body.</p>
<p>Experts at Quest Research are removing CCR5 from patients genes, replicating them and then putting them back. Dr. Lalezari says without CCR5 the virus can&#8217;t infect new cells and it eventually goes away. </p>
<p>Only time will tell if the new treatment can actually cure patients. So far Quest Research is treating ten patients with the gene therapy and experts call their results encouraging.</p>
<p>Professor Basil Donovan from the University of New South Wales in Australia says, &#8220;There is no guarantee that it would work in everyone you did it in, but the fact that it worked at all is encouraging.&#8221;</p>
<p>Dr. Jonathan Ball from the University of Nottingham in England says, &#8220;This is the first time the mutated gene has been harnessed to cure HIV infection.&#8221;</p>
<p>Doctors warn that this one case is an outlier and should by no means be viewed as a panacea to cure everyone living with HIV. The procedure itself kills about 30 percent of patients and is very expensive.</p>
<p>But experts are nevertheless blown away by this case, which you can read more about in the December issue of the journal, <em><a href="http://bloodjournal.hematologylibrary.org/cgi/content/abstract/blood-2010-09-309591v1">Blood</a></em>.</p>

<p>The medical community is questioning a San Diego doctor&#8217;s &#8216;&#8221;miracle&#8217;&#8221; treatment for multiple sclerosis. </p>
<p>Dr. David Hubbard prescribed a revolutionary treatment&#8211;venoplasty&#8211;to help alleviate the symptoms of MS that his 27-year-old son Devon was experiencing.</p>
<p>If an MRI scan of the patient&#8217;s brain reveals that a patient has decreased blood flow to the brain, Dr. Hubbard performs a surgical procedure to open up veins that carry blood out of the brain. He has now treated 60 patients using this technique and he claims 58 of them have seen symptoms decrease or disappear.</p>
<p>Although the work Dr. Hubbard is performing is part of a scientific study of the MS, the neuro-degenerative disease that attacks the central nervous system, he is collecting data not running a clinical trial.</p>
<p>Still patients are coming from all over the nation and Canada to pay $15,000 for this surgical treatment. Other doctors believe Dr. Hubbard is pedaling false hope not a cure.</p>
<p>Dr. Hubbard is not alone in thinking that MS is related to narrow brain veins.</p>
<p>Dr. Paulo Zamboni thinks the vein-narrowing allows blood to drain more slowly. He believes this causes iron to build up in the brain and cause MS.</p>
<p>Like Dr. Hubbard, for Dr. Zamboni, MS is a family affair. The <a href="http://news.bbc.co.uk/2/hi/health/8509106.stm">BBC reports</a> that he treated his wife using a vein widening procedure. </p>
<p>Unlike Dr. Hubbard, Dr. Zamboni ran MRIs on 500 MS patients in different postures to study blood flow. And he used 161 healthy patients as controls.</p>

<p>But a powerful rock band front man called for the first AIDS-free generation to be born in 2015, giving hope to those around the world that this disease can be stanched. </p>
