Siberian worms frozen in permafrost for up to 42,000 years thawed back to life



In the picture is the overall view of a female nematode. Two such creatures were successfully thawed out of 32,000 and 41,700-year-old permafrost and already showed signs of life. Shatilovich, Tchesunov, et al. [DokDokladyBiologicalSciences)

In a major scientific breakthrough, worms that have been trapped in permafrost for tens of thousands of years have been revived, and it is said

them Today, they are considered the oldest living animals in the world.

Sign of Life

Prehistoric nematodes are said to show signs of life and food after researchers from various institutions collaborated and thawed the permafrost They were trapped tens of thousands of years ago. The researchers apparently analyzed more than 300 permafrost samples of various origins and ages and found two of the most suitable samples containing nematodes, or better known as roundworms.

Both specimens came from the cold region of Yakutia in Russia, but one came from a permafrost wall in a squirrel tree, while the other was found in 201

5 in permafrost near the Alazeya River. Radiocarbon dating revealed that the permafrost in the squirrel is about 32,000 years old, while the permafrost near the Alazeya River is found to be about 41,700 years old.

The permafrost samples were placed in Petri dishes and kept at 20 degrees Celsius for several weeks. It is believed that the nematodes that have emerged from the permafrost are both female, and researchers have found that they have been showing "signs of life" ever since. In fact, for the first time since their capture, they are expected to move and eat permafrost during the Pleistocene

Long-term Cryobiosis

Researchers present the first data showing how multicellular organisms such as nematodes have the capacity for long-term cryobiosis. In their study, they showed in particular how such creatures can survive under natural cryopreservation over tens of thousands of years.

"It is evident that this ability suggests that the Pleistocene nematodes have some adaptive mechanisms that may be scientific and of practical importance to related fields of science, such as cryomedicine, cryobiology, and astrobiology," researchers .

The study was conducted by Russian scientists from the Moscow State University, the Institute of Physicochemical and Biological Problems of Soil Science, Pertsov White Sea Biological Station and the Moscow School of Economics. The research was also conducted in collaboration with researchers from the Department of Geosciences at Princeton University. The study appears in Doklady Biological Sciences

Cryonics

The study's findings may bring the conversation on cryonics back into the limelight. Simply put, cryonics is the practice in which a body is cryonically frozen in the hope of being restored or revived in the future, perhaps when a cure for a particular disease is coming. Nevertheless, even if there are already companies Englisch: bio-pro.de/en/region/stern/magazine/…3/index.html Many scientists are skeptical about the process because the human body is actually is very complex. However, it is useful to help conserve harvested organs to minimize damage before transplantation.
