>When a person gets malaria, a rhythmic dance takes place inside their body. The disease's telltale signs—cyclical fevers and chills—are caused by successive broods of parasites multiplying in sync inside red blood cells, then bursting out in unison every few days.
>Now, a study shows that even when grown outside the body, malaria parasites can still keep a beat.
>Reporting in the May 15 issue of the journal Science, researchers have uncovered rhythms in the parasite's gene activity levels that don't rely on time cues from the host, but instead are coordinated from within the parasite itself.
