Scientists have revived a ‘zombie’ virus that spent 48,500 years frozen in permafrost.
The amoeba-infecting viruses are still infectious, per experts.

Experts caution that the threat, although minimal, is being underestimated. Thawing could also release hazardous waste from the Cold War era, damaging ecosystems and endangering wildlife.
According to climate scientist Kimberley Miner from NASA Jet Propulsion Laboratory at the California Institute of Technology, the permafrost situation is worrisome.
It highlights the need to keep the frozen layer intact as much as possible.
