Case cracked: Team decodes HIV genome structure

A research team has decoded the secondary structure of a complete HIV-1 RNA genome. According to the report featured on the cover of the August 6 issue of the journal Nature, the team identified numerous highly structured motifs—such as the one pictured above—and can infer functions for many of these motifs.

Misery loves company— just ask a retrovirus

Retroviruses (red) form in infected cell and are transmitted to neighboring cell. Green proteins bind the cells. “Our hope is that somewhere down the road we will have a completely new antiviral strategy based on targeting cell-to-cell transmission,” says lead researcher Walther Mothes.
