Hunt for life under Antarctic ice heats up 

Nestled in a steep fjord beneath three kilometres of Antarctic ice is the lost world of Lake Ellsworth. The quest to find exotic microbial life that may have evolved in or beneath these lakes is on. Scientists have discovered a catalogue of bacteria elsewhere that mine their energy from rocks and minerals, and many assume that specialized microbes living in Antarctica’s hidden lakes might do the same. If Lake Ellsworth turns out to be sterile, this might provide clues about what constrains life on Earth and elsewhere in the Solar System.
