A 50,000-year-old virus that has been trapped deep within the Siberian permafrost has been brought back to life by a team of scientists.
More than a dozen prehistoric viruses were found by researchers for he French National Centre for Scientific Research, who made the discoveries while digging into ice cores deep underground in Siberia.
The viruses, which have been preserved in the ice for tens of thousands of years, are now being revived. One such virus is called Pandoravirus yedoma, which originated in the bodies of permafrost-preserved mammoths, wooly rhinoceros, and prehisotirc horses.
