Worms woke up after 41.700 years in the ice
These nematodes had been frozen for tens of thousands of years. Russian scientists have managed to bring them back to life.
These microscopic worms have survived tens of thousands of years asleep in a layer of ice, or rather in the heart of Siberian permafrost, a permanently frozen ground. They are two different species since it is a Plappus and a Panagrolaimus. If they are really "resurrected", they would be the two oldest living animals in the world, according to the work of Russian researchers published in the journal Doklady Biological Sciences. For several years, these researchers collected no less than 300 samples from several locations and dating from several eras. As permafrost acts like a giant freezer, it contains tons of cryogenic organisms, says Science and the Future. They found Panagrolaimus in a 32.000-year-old squirrel nest and Plectus in a sample collected 3,5 meters deep in the vicinity of the Alazeya river in 2015. Thanks to Carbonne 14, they were able to determine that the latter was 41 years old.
Back in the laboratory, they warmed both worms up to a temperature of 20 C ° in a box kneaded with nutrients. After a few weeks, the researchers noticed that the critters had started moving and feeding.
For the moment, experts prefer not to advance on this discovery, arguing that it is not impossible that the samples were contaminated, either during harvest or in the laboratory, by more recent worms. By the team's own admission, this possibility cannot be ruled out, but it nevertheless considers it unlikely due to the sterile environment of the research laboratories. They also indicate that no other modern organism has been found at the depth at which they discovered the animals. The deep layers are "cemented by ice" preventing migration of nematodes. "The depth of the seasonal thaw in the regions studied reaches 80 cm and never exceeds 1,5 m, even 9.000 years earlier during the Holocene thermal maximum. The age of living organisms in these strata therefore corresponds to the age sedimentary rocks "add the authors cited by Sciences et Avenir.
If true, such a discovery would be dramatic since no other multicellular organism ever came back to life after being frozen for such a long time.
An extraordinary ability to resist frost
Bacteria have been brought back to life after being frozen for tens of millions of years. There are also tardigrades, tiny multicellular organisms that look like cubs.
The latter can survive in very hostile environments such as -272 temperatures at + 150 ° C or space vacuum. They could also be awake after 30 years of freezing, but they did not survive long.
It was already known that the nematodes which colonized all the surfaces of the Earth could very well resist freezing thanks to a state of cryptobiosis, a very slow state of life, and a clever organization of ice crystals and the secretion of a sweet liquid. These last two adaptations protect their cells. Because what often "kills" frozen living beings is the destruction of tissues following the freezing of the water contained in them.
According to Russian researchers, these "roundworms" possess a number of adaptive mechanisms that can provide new scientific insights. They dream of breakthroughs in medicine or astrobiology, the branch of science that studies the origin of life in the universe.
However, there is no need to go defrost all cryopreserved people. Because human beings have little to do with these verses. If one day we can bring these people back to life, which is not excluded, we probably will not have to discover it. Indeed, if there are similarities at the cellular and genetic level, we are also much more complex. For example, worms do not have brains. To freeze and bring back to life an organ like this is a whole other pair of sleeves.
