US team discover life in Antarctic lake

A surprising amount of living cells have been retrieved from 800m below the freezing surface.

The samples retrieved from Lake Whillans are the first in Western Antarctica to show evidence of life. The microbes are believed to be actively using oxygen and have been sealed below the ice for more than 100,000 years. In recent years several teams have worked towards retrieving samples from subglacial lakes however success until now has proved elusive.

One of the biggest challenges the team faced was ensuring that the samples weren't contaminated by microbes from the surface but despite this researchers are confident that what they've found did come from the depths of Lake Whillans. "This is a big deal - and exciting," said glaciologist Martin Siegert. "The first clean access to a subglacial lake system."

"Cells containing DNA have emerged as the first evidence of life in a subglacial lake in West Antarctica."

100,000 years... So if any contagious bacteria, viruses or diseases are found.... We won't be immune? Good point. Hope they're careful, just in case.

Id be more worried about catching a cold from antarctic bacteria

It is unlikely that they are any danger for humans. But to me this proves that there is probably alien life out there. Please explain your reasoning for both of these statements. I make these observations... 1. Ebola and Marburg viri passed from animals to humans after developing in animals segregated from humans when humans encroached on the animals' territories which previously where free of humans. Humans have had no opportunity to develop immunity to these organisms. 2. The ancestors of the organisms found in Lake Williams were trapped in the lake after the lake had been closed off from th...

cool. i would be more surprised if no life was found in the lake.

100,000 years... So if any contagious bacteria, viruses or diseases are found.... We won't be immune? We've survived these: Deep in the mine, within a pocket of salt water trapped in a 250 million-year-old salt crystal, two biologists and a geologist discovered the 2-9-3 virgibacillus bacteria. This would be unremarkable save for the fact that this bacteria was 100 million years older than the dinosaurs... and it was still alive. http://boingboing.net/2009/06/17/salty-microbe-may-be.html

I agree with Nasty Gash. These microbes could be potentially dangerous. @Abramelin - Just because our ancestors may have developed an immunity to a disease doesn't mean the immunity is still passed on to us. That's what makes bio-warfare so dangerous. All you need to do is find a long-gone "bug" cultivate it and release it. As we haven't been exposed to it recently, we probably wouldn't have an immunity to it bringing on an epidemic.

But the salt bacteria are 250 millions of years old, and I read about it when I was still in highschool, some 40 years ago. These bacteria were already there long... [More]
