Fishing for extremophiles

3058072724_1f9f55558a_b In contrast to the mesophiles - that would be you and me! - that live in the temperate climes that prevail over most of our world, what life forms may lie in the dark hidden lakes of the Antarctic? Nature:

Over the past 40 years, radar imagery has revealed around 150 freshwater lakes of various sizes and ages beneath the massive Antarctic ice sheet. Some have been isolated from the outside world for millions of years, raising the possibility that they hold unique life forms. The dark, nutrient-deprived environment of the lakes could resemble conditions on Jupiter's moon Europa, which is assumed to hold a large ocean beneath its frozen surface.

Three projects designed to carefully sample the lakes, at least one of which is as large as Lake Ontario, will happen beginning next year. Hat tip: Alan Boyle
