After 46,000 years, ancient worms were resurrected from permafrost.


Ancient roundworms, frozen 46,000 years ago, revive and demonstrate life's ability to pause indefinitely. 

Published in PLOS Genetics, the discovery reveals how nematodes survive extreme conditions for millennia. 

Scientists thawed two female worms found in a fossilized burrow in the Arctic's permafrost. 

Revived by water, the worms, Panagrolaimus kolymaensis, reproduced generations before dying in the lab. 

Radiocarbon dating places the worms' freeze period in the late Pleistocene, between 45,839 and 47,769 years ago. 

The millimeter-long worms enter cryptobiosis, a dormant state, to endure extreme low temperatures. 

Research offers valuable insights into life's resilience and survival mechanisms. 

Anastasia Shatilovich from Russia's Institute of Physicochemical and Biological Problems led the study.
