30,000 year-old virus emerges from Siberian ice

A virus that has been preserved in permafrost for 30,000 years in Siberia has resurfaced as the global ice levels lower. While the virus only attacks amoebae, scientists are now worried that as ice levels continue to deplete, human, animal, and vegetation populations will be at risk of ancient, re-emerging viruses.
