Hot Bugs

It seems global climate change could have a huge affect on insects. There will likely be more of them as the world warms, according to most biologists. Some garden variety bugs could start producing millions of offspring (instead of a couple hundred thousand)...

Baby birds can learn their songs from adults other than their parents. The same may hold true for human infants.

Dark Energy

For years scientists have theorized about what makes up most of the universe. Astronomers call it dark energy because it can’t be directly seen and also because they know so little about it.

Birds get it. Dogs get it. And people get it. Depression is a biochemical abnormality that is found in animals. Now a new drug similar to a commonly prescribed human anti-depressant is showing signs of hope for dogs with the blues.

Clovis Comet
Douglas Kennett

A controversial new theory about the disappearance of Clovis man and 35 North American animal species is making waves in geology circles. Two University of Oregon anthropologists are part of a group of 26 who think a comet crashed into Earth 13,000 years ago, causing...
Positron Possibility

Scanning for cancer gets more sophisticated all the time. Positron Emissions Tomography is one of the best and most widely used methods to find tumors when they are small enough to cure patients. An old idea is bringing high-energy physicists and radiologists...
Math Whiz

Two undergraduate math teams took home the top math modeling prize after beating out other top flight schools. They came up with the simplest way to divide a state into congressional districts based on population rather than politics. They solved the complex math problem...
Volcanic Revelations

On the 27-year anniversary of Mt. St. Helens we look back to the big eruption and measure how far science has come–especially when it comes to understanding the role of volcanoes in climate change.

Ocean Space

What goes on beneath the waves is just about as unexplored as outer space. But that is about to change. The University of Washington just got the greenlight to start imagining a one-of-a-kind underwater laboratory to study our own oceanic inner space.

Boiled Again

Broccoli is generally viewed as a good veggie to eat to prevent cancer. Brussel sprouts, cauliflower and green cabbage contain similar properties. But scientists recently discovered that boiling them destroys much of the health benefit.

Chewy Bacteria
Most people spend a lot of time and energy trying to kill bacteria–especially the ones in our mouths. Most of the 600 types of bacteria are helpful but some help destroy our teeth. Now dentists are trying to use new DNA knowledge to identify bad bacteria that can do more than just rot teeth.

Whale Workers
Narwhals near Greenland
Odd looking sea creatures that look like they were plucked from mythology are being put to work below the icy north Atlantic Ocean. These tusked creatures are called narwhals and are the latest tool for capturing information about water temperature and salinity in one of the...

Deep in the dark ocean, hot minerals are bubbling out of the Earth’s crust, superheating the water. The hottest of the hydrothermal vents are called black smokers and they are not quite as quiet as scientists thought.

Pathological Protein
What happens when good proteins go bad? Well, disease, of course. Mad cow disease is probably the most familiar involving clusters of bad proteins called prions. They can jump across species and turn perfectly good proteins into microscopic miscreants.

Supercell Summer

A spate of spring storms is leaving many people wondering if this summer will be a brutal one. Scientists won’t make predictions about severe storms, hurricanes or heat waves. But if disaster strikes a new system develeoped from research at the San Diego...
Math Angst

Getting a math problem right doesn’t just help students. Sometimes good math helps in the real world, too. An Illinois man is out of the running…uh biking…for the Guiness Book of World Records thanks to a few too many math errors.

Word Soup
Autistic kids can learn, a new study says. Researchers at University of Washington found that toddlers can distinguish between common words and unfamiliar words. And, autistic kid brains react in a similar way to typical kid brains when it comes to hearing those words in reverse. From this so-called...

Ice Hole
Ross Ice Shelf at Bay of Whales
Scientists just unlocked a time capsule buried in the Antarctic ice. An international team drilled through snow, ice, rock and mud to retrieve a climate history of the icy continent going back 10 million years. It will take decades to uncover the secrets hidden in the...

Cloudy Future
Jet engines roar above Earth all day long, creating long, white trails of water vapor. Scientists have determined that these contrails are creating cirrus clouds but the effect on climate change still remains a bit cloudy.

Picture elephants walking past invisible metal detectors–much like herds of people at airports. Instead of rushing off to their flights, these pachyderms are merely roaming their favorite trails. The invisible TrailGuard is designed to help protect endangered species from poachers....
