In Mono Lake, California, NASA says that a form of life, never before found on Earth, is thriving. This potato-shaped microbe is not proof of aliens among us but it is a big deal for scientists.
NASA’s announcement on Thursday of radical new bacteria that survive by incorporating arsenic instead of phosphorus into its DNA has shifted what scientists consider necessary for life to exist.
This is opening up the possibility of life existing on other planets previously thought inhospitable for life as we know it. Researchers now plan to take a closer look at Mars for this new arsenic-loving bacteria.
