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, is a genus of giant virus known from two species, Alphapithovirus sibericum, which infects amoebas, [2] [3] and Alphapithovirus massiliense. [4] It is DNA-based and is a member of the nucleocytoplasmic large DNA viruses clade.
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 ...
Resurrection biology aims to bring strings of molecules and complex organisms back to life in a bid to identify new sources of drugs, achieve de-extinction and more.
Mollivirus sibericum is a giant virus discovered in 2015 by French researchers Chantal Abergel and Jean-Michel Claverie in a 30,000-year-old sample of Siberian permafrost, where the team had previously found the unrelated giant virus Alphapithovirus sibericum.
Yedoma / ˈ j ɛ d ə m ə / (Russian: е́дома) is an organic-rich (about 2% carbon by mass) Pleistocene-age permafrost with ice content of 50–90% by volume. [1] Yedoma are abundant in the cold regions of eastern Siberia , such as northern Yakutia , as well as in Alaska and the Yukon .
Pandoravirus is a proposed genus of giant virus, first discovered in 2013. [5] It is the third largest in physical size of any known viral genus, behind Pithovirus and Megaklothovirus. [6]
