Bacterium found under glacier reawakened after 120,000-year sleep

A tiny microbe found two miles under Greenland ice has been reawakened from a 120,000-year sleep.

Researchers coaxed the dormant frozen microbes, back to life by carefully warming the ice samples containing them over a period of 11-and-a-half months.

As the bugs, named Herminiimonas glaciei, awakened and began to replicate, colonies of very small purple-brown bacteria started to appear.

H. glaciei belongs to a rare family of ‘ultramicro’ bacteria that live in extreme environments.
