Experts from a soil science institute in Moscow collaborated with Princeton University in New Jersey, USA. They first analyzed more than 300 frozen worms and selected suitable frozen worms for thawing. As a result, only two frozen nematodes were suitable, and one of them was inferred to survive 41,700 years ago and the other 32,000 years ago.
Both nematodes were found in the Sakha Republic, one of the coldest places in the world. Scientists mentioned that after thawing, the nematodes showed signs of life and began to move and eat.
This latest breakthrough shows that multicellular organisms have the ability to survive for long periods of time, even tens of thousands of years, when naturally cryopreserved.
The scientists mentioned that it is clear that such survival ability shows that nematodes from the Pleistocene have certain regulatory mechanisms, which may have practical contributions to many scientific fields, such as cryogenic medicine, cryobiology and astrobiology.
This discovery is a big breakthrough for human cryonics technology. It may one day really make the leap from science fiction to reality. One of the ultimate goals is to freeze humans for a long time, perhaps several centuries, and send them to distant interstellar exploration.
