'Zombie' Virus Reanimated After 50,000 Years In Siberian Permafrost
French researchers have reanimated over a dozen prehistoric viruses which have been trapped deep within the Siberian permafrost for nearly 50 million years, according to a pre-print study. After obtaining seven ancient permafrost samples, scientists from the French National Centre for Scientific Research were able to document 13 never-before-seen viruses that had been lying dormant in the ice.
