TRIBUNJAMBI.COM – Not long ago, Russian scientists reported that they had managed to "revive" two species of worms that had been frozen for more than 40,000 years.
Two roundworm or frozen nematode species are 30,000 and 42,000 years old. The discovery was made by four different institutions in Moscow in collaboration with Princeton University.
At first, they wanted to know if multicellular organisms could be revived after long periods of "falling asleep" in extreme cold. To this end, they explored the cold region of eastern Russia and collected 300 samples of flooring that continued to be frozen or often called permafrost.

After collecting enough permafrost deposits of different ages and regions in Siberia, they return to the laboratory and seek to revive organisms in sediments.
The results were quite surprising, scientists were able to trace the signs of prehistoric life from two samples taken after extraction.
A sample was taken from a fossilized squirrel hole near the Alazeya River in northeast Yakutia, Russia. Read: There are hot spots at several points, it will be the green community
Other samples of permafrost come from the Kolyma River in northeastern Siberia, and there is no sign of it. Nearest sedimentary age is about 42,000 years old, scientists report.
Conclusions published in the May issue of the journal Doklady Biological Sciences "We have obtained the first data showing the ability of these multicellular organisms to fall asleep over the long term on Arctic permafrost," Newsweek said Friday. (27/07/2018)
"The duration of cryopreservation (cooling of cells / organs at very low temperature) nematodes according to the age of deposition, 30 000-40 000 years," add the researchers.

Summed up from Live Science on Friday 27/07/2018, despite its small size (only about 1 millimeter), nematodes are known to have impressive abilities.
These animals are known to live 1.3 meters below ground level. In other words, they can live more deeply than other multicellular animals. However, nematodes are not the first organisms that wake up after thousands of years of frost in the ice.
Previously, another group of scientists identified the giant resuscitated virus after 30,000 years in Siberian permafrost (*,
