Siberian Permafrost Reveals Still Infectious Ancient Giant Virus

(Undated) -- A French research team is warning of potential dangers that ancient viruses may pose. "Nature News" reports the pair recently revived a giant virus that had been buried in Siberian ice for about 30-thousand years, and it was found to still be infectious. Fortunately, the newly-thawed virus only targets amoebae. However, some scientists say rising global temperatures could potentially unleash other frozen ancient viruses that remain infectious and could threaten human health.
