48,500-Year-Old Zombie Virus Revived In Russia: What Is The Pandoravirus & Is It Killer?

Climate change due to global warming is rapidly thawing
the ancient permafrost, which may pose a new threat to
humans, according to researchers who revived nearly
two dozen viruses- including one frozen under a lake
more than 48,500 years ago.
European researchers examined ancient samples
collected from permafrost in the Siberia region of
Russia. They revived and characterized 13 new
pathogens, what they termed "zombie viruses and
found that they remained infectious despite spending
many millennia trapped in the frozen ground, according
to a Bloomberg report.
