...half years without heat, food or sunlight and see how you do. A team of National Science Foundation researchers just discovered a species of Antarctic organisms that has accomplished exactly that - and the microbes' unlikely survival can tell us a lot not just about the adaptability of life on Earth, but the prospects for it on Mars...
...warmer, wetter land than it is now, but continental migration pushed it from place to place, leaving it - for the current epoch at least - at the bottom of the planet, where it became little more than a frozen desert. Its valleys are some of the driest places on the Earth, receiving less than 4 inches of precipitation per year. Species that thrived when Antarctica was green would have been entirely wiped out, unless they could adapt - and fast. (See pictures of life beneath Antarctica...
...Mikucki refers to the subglacial pond as "a unique sort of time capsule from a period in Earth's history," but it also has lessons for scientists studying Mars, an entire planet that is in many ways a time capsule too. Mars, like Antarctica, was once warm and wet, but the slow loss of its atmosphere also meant the loss of much of its moisture and surface heat. Still, the place was warm and wet long enough for life to have taken hold - life that would have then had to retreat into underground water deposits and make the same kind...

...along with helmets, locks, and lights—from the superintendent’s office in each house, said Karen McKinnon ‘10, the chair of the Environmental Action Committee. The new program will launch April 25 at the Environmental Action Committee’s Earth Day festivities, where students will be able to see the new bikes and sign waivers to participate in the bike sharing. The program will debut just two months after the city of Boston announced that it would move ahead with a bike-sharing program, set to launch in 2010, that aims eventually...
