French researchers have resurrected the "Phoenix virus," a "fossil virus" that lay dormant in the human genome. The retrovirus infected our ancestors millions of years ago, and is apparently still infectious in its new revivified form.
Link (via William Gibson)A team led by Thierry Heidmann at the Institut Gustave Roussy in Villejuif, France, near Paris, decided to try to awaken the ancestor of an entire family of HERVs called HERV-K(HML2). To "correct" for mutations, the researchers took dozens of known HERV-K(HML2) sequences and aligned them to create a so-called "consensus" sequence. Then they converted this information into a complete viral genome.
The researchers showed that the newly crated virus could infect a variety of human cell lines and replicate. But its infectivity was extremely low, perhaps because human cells have evolved resistance against such viral invaders.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
