Scientists in France have awoken a gigantic, ancient virus from its 30,000-year-long slumber in Siberian permafrost — and found that it's ready to infect again. There’s no need to scour eBay for a HAZMAT suit: the virus, dubbed Pithovirus sibericum, only infects single-celled amoebas. However, the discovery has scientists wondering what other microbes are hidden in melting permafrost awaiting another chance to infect.
