Scientists revive 48,500-year-old 'Zombie Virus' buried in ice

The thawing of ancient permafrost due to climate change may pose a new threat to humans, according to researchers who revived nearly two dozen viruses - including one frozen under a lake more than 48,500 years ago. European researchers examined ancient samples collected from permafrost in the Siberia region of Russia. Scientists have long warned that the thawing of permafrost will worsen climate change by freeing previously trapped greenhouse gases like methane.
