Tiny frozen microbe may hold clues to extra-terrestrial life
A novel bacterium that has been trapped more than three kilometres under glacial ice in Greenland for over 120 000 years, may hold clues as to what life forms might exist on other planets.
“These extremely cold environments are the best analogues of possible extraterrestrial habitats”, said Dr Loveland-Curtze, “The exceptionally low temperatures can preserve cells and nucleic acids for even millions of years. H glaciei is one of just a handful of officially described ultra-small species and the only one so far from the Greenland ice sheet; studying these bacteria can provide insights into how cells can survive and even grow under extremely harsh conditions, such as temperatures down to -56˚C, little oxygen, low nutrients, high pressure and limited space.”
