Ancient Antarctic community of bacteria discovered

November 29, 2012 - A study by polar researchers has revealed an ancient community of bacteria able to thrive in the lightless, oxygen-depleted, salty environment beneath nearly 20 metres of ice in an Antarctic lake.

The research, funded by the National Science Foundation and Nasa, provides clues about biochemical processes not linked to sunlight, carbon dioxide and oxygen or photosynthesis.

The authors of the study say it may explain the potential for life in salty, cryogenic environments beyond Earth, where energy in ecosystems is typically fuelled by the sun.

Antarctic bacteria a clue to different kinds of life: study

(Reuters) - A study by polar researchers has revealed an ancient community of bacteria able to thrive in the lightless, oxygen-depleted, salty environment beneath nearly 70 feet (20 metres) of ice in an Antarctic lake, giving insight into the unique ecosystem. The research, funded by the National Science Foundation and NASA, provides clues about...

Ancient microbes found in buried Antarctic lake

Beneath the icy surface of a buried Antarctic lake, in super-salty water devoid of light and oxygen that is also cold enough to freeze seawater, researchers have now discovered that a diverse community of bacteria has survived for millennia. The findings shed light on the extreme limits at which life can live not just on Earth, but possibly alien...
