Scientists discover worms that have been sleeping in Siberia for 40,000 years – Technology News, Firstpost



A team of Russian scientists announced earlier this month in the journal Doklady Biological Sciences that they have discovered ancient nematode worms. The worms are said to be able to revive after being buried in permafrost for at least 32,000 years.

If this discovery proves to be legitimate, it would be the longest surviving return never before seen in a complex. multicellular organism. This could even eclipse the tardigrade, which is also known for extreme conditions.

According to a report in Gizmodo the worms were taken from the frozen soil in the Kolyma River Lowlands in northeastern Siberia. More than 300 samples of frozen soil were extracted, of which 2 samples were the worms. One of them, which belonged to the genus Panagrolaimus, came from a buried squirrel gate, which was 32,000 years old, and the other from the genus Plexus of a 40,000-year-old glacier.

The intact nematodes were then isolated and in the next few weeks The researchers discovered the flickering of life. These samples were stored at 20 degrees Celsius (68 Fahrenheit) and left in a Petri dish surrounded by food.

The worms ate the food and even developed new family members. These new, cloned family members were then bred separately and they thrived.

Contamination of worms can not be ruled out, but the researchers say they maintained strict sterility procedures. In addition, the researchers argue that it is impossible for the New Age nematodes to snake down 100 feet and 15 feet where the ice samples were buried.

Even if this is not the first time that organisms have been revived. According to the report in Science Alert scientists have taken out spores from Bacillus bacteria that were hidden in 250 million year old salt crystals and brought them back to life.

But you have not seen anything like that before.

Of these worms, which pose a danger to humans, nothing is known yet. But the melting of permafrost could release pathogens that have been trapped in such cold environments for tens of thousands of years.

Let's just hope that the melting of Siberia's ice will only get us those slumbering worms.
