Lake Vostok Found Teeming With Life
jpyeck writes "Lake Vostok, Antarctica's biggest and deepest subsurface lake, might contain thousands of different kinds of tiny organisms — and perhaps bigger fish as well, researchers report. The lake, buried under more than 2 miles (3.7 kilometers) of Antarctic ice, has been seen as an earthly analog for ice-covered seas on such worlds as Europa and Enceladus. It's thought to have been cut off from the outside world for as long as 15 million years. But the latest results, reported in the open-access journal PLOS ONE, suggest that the lake isn't as sterile or otherworldly as some scientists might have thought. More than 3,500 different DNA sequences were identified in samples extracted from layers of ice that have built up just above the surface of the lake."
They should get one of the clipboard guys to chug a bottle and see if he mutates.
That ends badly
...it turns out to be life as we know it

If you read TFA, you'll see that 1) they did sequence DNA, 2) they found many, many species which are not the usual ones associated with contamination due to methodology, and 3) they found organisms that can theoretically survive in the extreme and varied environments believed to be present in the lake (thermophiles near suspected geothermal areas, halophiles in brackish/salty water, etc). As a microbiologist, I find it fascinating that the authors not only provide a list of species, but go so far as to paint a complete picture of how each could possibly exist in a completely functioning ecosystem. For example, they found organisms responsible for carbon and nitrogen fixation, and hypothesize that these same species will also be found throughout the lake water in their various niches.
