Pandoravirus yedoma is a virus that originated 48,500 years ago which was discovered in the deep Siberian permafrost in 2022. The scientists also revived 13 new pathogens and characterized them as 'zombie viruses'. It has been shown to infect amoeba cells (particularly A. castellanii) killing them in the process. [1] [2]
Alphapithovirus sibericum was discovered in a 30,000-year-old sample of Siberian permafrost by Chantal Abergel and Jean-Michel Claverie of Aix-Marseille University. [ 2 ] [ 15 ] The virus was discovered buried 30 m (100 ft) below the surface of a late Pleistocene sediment.
Also in 2014, two ~30,000 years old giant virus species, Pithovirus sibericum [10] and Mollivirus sibericum, [11] were discovered in the Siberian permafrost and they retained their infectivity. Like the other giant viruses with large genomes , they are larger in size than most bacteria and pose no risk to humans, as they infect other ...
Ancient “zombie viruses” frozen in melting Arctic permafrost could fuel a new pandemic if unleashed by climate change, scientists have warned.. Global heating is enabling increased human ...
Mollivirus sibericum is a spherical DNA virus with a diameter of 500–600 nanometers (0.5–0.6 μm). [1] [2] Mollivirus sibericum is the fourth ancient virus that scientists have found frozen in permafrost since 2003. [3] It has a sister taxon, Mollivirus kamchatka. [4]
Scientists have revived a worm that was frozen 46,000 years ago — at a time when woolly mammoths, sabre-toothed tigers and giant elks still roamed the Earth.
