If I get eight hours of sleep, I’m fine. A microscopic Arctic animal is 24,000 years old, and it turns out well on the other hand. A new study details the remarkable journey of the bdelloid rotifer, a tiny freshwater creature that has survived for millennia in Siberia̵7;s frigid soils.
Stas Malavin, from the Institute of Physicochemical and Biological Problems in Soil Science in Russia, said: “Our report is the hardest proof to date that multicellular animals are resistant to tens of thousands of years of cryptobiosis. a state of almost complete metabolism” in the Cell Press command.
Malavin is the co-author of an article describing the remarkable achievements of Rotifer’s survival. published in the journal Current Biology on Monday.
Rotifers are also called “wheel animalcules,” from the Latin root of their name, which is related to the spinning “wheel” of tiny feathers. At one end of the body, the “animal” part means they are small animals.
Malavin’s team specializes in extracting frozen soil samples in remote areas using drilling techniques. The rotifers come from a depth of about 11 feet (3.5 meters). The researchers used radiocarbon dating. which is a method for determining the age of organic matter until the date of the animal when dissolved It can be replicated mainly by cloning itself.
Permafrost is a gift that keeps on giving. Siberian rotifers get along well with, reserved and an . Mammals cannot be resurrected.
Science testifies to the impressive resilience of tiny creatures. Tardigrades – known as water bears – are tiny creatures that can survive freezing, radiation and. Researchers have also discovered .

Researchers freeze and thaw rotifers in laboratory experiments. The findings suggest that the animal’s wheels have an unknown mechanism for surviving the slow freezing process. The team intends to find other animals. that may continue to survive in a similar situation If scientists can understand how these animals protect and heal themselves They may be able to improve cryonic systems for more complex animals such as humans.
“What you should know is that Multicellular organisms can be frozen and stored for thousands of years. then can be resurrected which is the dream of many novelists,” Malavin said.
“Of course, the more complex the organisms are. The more difficult it is to heal,” he notes, with a big caveat for all humans to hibernate: “For mammals. It’s not possible right now.”
