A 30,000-year-old giant virus has been revived from the frozen Siberian tundra, sparking concern that increased mining and oil drilling in rapidly warming northern latitudes could disturb dormant microbial life that could one day prove harmful to man.
The latest find, described online Monday in the Proceedings of the National Academy of Sciences, appears to belong to a new family of mega-viruses that infect only amoeba. But its revival in a laboratory stands as “a proof of principle that we could eventually resurrect active infectious viruses from different periods,” said the study’s lead author, microbiologist Jean-Michel Claverie of Aix-Marseille University in France.
“We know that those non-dangerous viruses are alive there, which probably is telling us that the dangerous kind that may infect humans and animals — that we think were eradicated from the surface of Earth — are actually still present and eventually viable, in the ground,” Claverie said.
