Ancient Roundworms Allegedly Resurrected From Russian Permafrost


Skeptics cite possibility of ancient samples’ contamination by contemporary organisms

The permafrost of Russia’s Siberian heartland has yielded an array of impressive finds in recent years. Last September, a local resident wandering along the banks of a river in the republic of Yakutia discovered the roughly 50,000-year-old remains of an extinct lion cub almost perfectly preserved by the permanently frozen ground. In 2015, Russian scientists chanced upon the similarly well-preserved remains of two ancient lion cubs dubbed Uyan and Dina.

Now, the Siberian Times reports, Yakutia’s frigid ground has produced yet another revolutionary discovery: Two nematodes, or roundworms, preserved in the Arctic permafrost for around 40,000 years have allegedly come back to life after being “defrosted” by researchers. If proven true, the claim—newly catalogued in the journal Doklady Biological Sciences—would make the roundworms Earth’s oldest living animals, shattering the record for the longest time an animal can survive cryogenic preservation.

According to New Atlas’ Michael Irving, a team of Russian scientists working in collaboration with Princeton University found the viable specimens while analyzing more than 300 soil samples taken from the Arctic permafrost. One of the samples was retrieved from a squirrel burrow located in the Duvanny Yar outcrop and dates to about 32,000 years ago. The older sample, which dates to about 41,700 years ago, was found in a glacial deposit near the Alazeya River. Both nematodes are believed to be female.

Irving writes that the worms were initially stored in a lab kept at -4 degrees Fahrenheit. Later, the samples were defrosted in a petri dish alongside an enrichment culture designed to encourage their growth. After spending several weeks basking in their new 68-degree Fahrenheit environment, the nematodes, against all odds, began moving and eating.

2. Yep, I stumbled across it, knew I hadn't heard, decided to post it here.

Ancient roundworms that froze during the Ice Age have been brought back to life

Cryonics is the practice or technique of deep-freezing the bodies of people who have just died, in the hope that scientific advances may allow them to be revived in the future.

The prehistoric roundworms (nematodes) that were alive between 32 000 and 42 000 years ago, when woolly mammoths roamed the earth, were found in two areas of Siberia in Russia.



Duvanny Yar
They were found in permafrost samples taken from the inside of an ancient squirrel burrow and from a site near a river and were kept in storage before being thawed.

According to the published research the nematodes showed signs of life after they had been defrosted in a laboratory at The Institute of Physico-Chemical and Biological Problems of Soil Science near Moscow. The worms reportedly “started moving and eating”.

3. Did they ever prove it, I wonder?

4. I would think so, as Princeton University scientists worked on the project with them,

and the Smithsonian Magazine wrote it up.

Later, if I remember, I can look for more information, being interested in finding out more, myself.
