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

See if anything floats to the surface? Probably the easiest way to confirm.
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.
There is probably a civilization of super piranha, that have been surviving by cannibalism for 15 million years, creating a race of super big, super powerful, mean, man eating monsters.
Troll is not a replacement for I disagree.
Could we please stop saying "more than" in scientific contexts, except when needed? This phrase is intended to denote situations where we just know a lower boundary of the correct value, but in recent time it's being (ab-)used mostly for a dramatic effect. I really wish people would either give precise figures, or when this is not practical, use the words invented to mark numbers as approximations, like "roughly" or "about". Statistically speaking, the difference is that "roughly" implies an effort to find a "simple" number close to the correct expectation value, but "more than" implies we picked just some number that's surely below the confidence interval.
So where am I supposed to get clean water for my scotch?
Mandrake, I suggest you drink only distilled water, or rainwater, and only pure-grain alcohol.
No left turn unstoned.
It can be if you mix it with something (such as the aforementioned scotch).

I do metagenomics in a Deep Biosphere project and have to wonder how this article even got published. I mean, 80% contamination rate is just insane. We've been plagued by contamination as well (1-3% that I can tell). Sure, it's easy to filter out e.g. human sequences from the data, but what about the 1,000 or so bacterial species that live on the human skin? They conveniently skip this part in the article..
