Danish scientists from the University of Orchus have discovered giant viruses that could survive about 48,500 years in Greenland’s ice seeds. Research Results published In the scientific journal microbiome.
The researchers examined the examples of dark ice, red snow and cryochonitis (organo-mineral sediment) collected from the surface of the Greenland glacier shield. The viruses were not found in deeper layers, but on the surface of the glaciers in which they interact with microsbars. These algae contribute to the melting of the ice by creating a nutrient environment for germs and accelerate the destruction of the glacier cover.
Pandoravirus Yedoma virus drew special attention to experts who can be infected with amoeba after dissolving the ice. Their size reaches a micrometer and the genome has about 2.5 million nucleotides, which makes it one of the largest famous viruses in the world.
Previously, such viruses were believed to survive only in Siberian Permafrost or deep ocean deposits. The new discovery is expanding the boundaries of a possible environment of living spaces.
Investigation of ancient viruses in 2013, the French scientist Jean-Michelle Keyverti’nin for about 30 thousand years Pithovirus Sibericum virus “revives”. In 2022, Pandoravirus Yedoma was first removed from Siberia Permafrost. Now the virus has been found in Greenland, which confirms its wide prehistoric distribution.
The accelerated melting of glaciers and permafrost against the background of global warming can lead to the release of microorganisms that have been in anabios for tens of thousands of years. Scientists warn: There is a risk of new infectious threats in the absence of immunity to such pathogens.
