Scientists have brought back to life a worm that was frozen 46,000 years ago in the Siberian permafrost.

The revival of this ancient roundworm species highlights the resilience of life and the significance of preserving biodiversity in the face of a rapidly changing world.

Scientists have revived a worm that was frozen 46,000 years ago — at a time when woolly mammoths, sabre-toothed tigers and giant elks still roamed the Earth.

Russian scientists have found and revived the roundworms frozen 46,000 years ago under the ice of Siberia permafrost.

Scientists have achieved a remarkable feat by reviving a worm that was frozen for an astonishing 46,000 years. This remarkable discovery brings to life an ancient organism from a time when woolly mammoths, sabre-toothed tigers, and giant elks roamed the Earth. The roundworm, which belongs to a previously unknown species named Panagrolaimus kolymaenis, was found…

(CNN) — Scientists have revived a worm that was frozen 46,000 years ago — at a time when woolly mammoths, sabre-toothed tigers and giant elks still roamed the Earth.

Some organisms, such as tardigrades, rotifers, and nematodes, can survive harsh conditions by entering a dormant state known as “cryptobiosis.” In 2018, researchers from the Institute of Physicochemical and Biological Problems in Soil Science RAS in Russia found two roundworms (nematode) species in the Siberian Permafrost. Radiocarbon dating indicated that the nematode individuals have remained in cryptobiosis since the late Pleistocene, about 46,000 years ago. Researchers from the Max Planc...
