After the thawing of ancient permafrost, researchers who revived nearly two dozen viruses – including one frozen under a lake more than 48,500 years ago.
- NDTV – 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.
- NEW SCIENTIST – Seven types of viruses that have lain frozen in the Siberian permafrost for thousands of years have been revived. The youngest were frozen for 27,000 years, while the oldest was on ice for 48,500 years – making it the most ancient virus resuscitated so far.
- SCIENCE ALERT – The team behind the work, led by microbiologist Jean-Marie Alempic from the French National Centre for Scientific Research, says these reanimating virusesare potentially a significant threat to public health, and further study needs to be done to assess the danger that these infectious agents could pose as they awake from their icy slumber.
