“Fossil” Virus Resurrected from Human Genome

Fossil Virus ImagesFrench 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.

The researchers showed that the newly crated virus could infect a variety of human cell lines and replicate. But its infectivity (sic) was extremely low, perhaps because human cells have evolved resistance against such viral invaders.
