4.Siberian Giant Virus
A French research team recently unearthed a 30,000-year-old giant virus from the Siberian permafrost—and it’s still infectious. The virus was discovered in a soil sample from 98 feet beneath the ground. It is wider than other giant viruses, and large enough to be seen through a standard microscope.
The team fished for viruses using amoebas, their target hosts, as bait. The amoeba starting dying, and researchers discovered they were laden with these ancient giants. Unlike most viruses, which attack the nucleus, sibericum sets up replication factories in the host’s cytoplasm. Although sibericum only targeted amoeba, another giant virus dubbed Marseillesvirus recent infected an 11-year-old boy in France. It is possible that dangerous viruses also lurk deep underground. More than any other factor, human activities like drilling and mining are likely to unearth these slumbering monsters.
