Mar 4, 2014 — A team of scientists says it has reawakened an ancient pathogen. It's not dangerous to humans, but they warn that climate change could free potentially deadly organisms locked in permafrost.
Oct 18, 2013 — Researchers say naturally occurring viruses that target bacteria might one day help help treat human infections with germs that are resistant to antibiotics. The research is still in the early stages, and there are quite a few challenges to overcome before a treatment can even be tested in humans.
Jul 18, 2013 — The Pandoravirus is so big you can see it in an ordinary microscope. Scientists say its size may have helped fool amoebas and other potential hosts into eating it. But this virus doesn't pose a threat to humans. It's more of a Trojan virus than a surprise from Pandora's Box.
Jan 17, 2013 — Flu viruses hijack the machinery inside animal cells to replicate. The theft is a complicated process that takes time. If the virus leaves the cells too early or too late, the risk of infection falls.
Sep 28, 2012 — Virologists have published the genome sequence of the new coronavirus, which has killed one man and hospitalized another. The mystery virus is most closely related to coronaviruses that infect bats in Southeast Asia. But this doesn't necessarily mean that the men caught the virus directly from bats.
Aug 29, 2012 — So far, two Missouri farmers are the only known cases of the tick-borne virus in the world. But experts are sure they'll find more. The men recovered but suffered serious illness that required hospital care and weeks of convalescence.
