It's well known that the human body functions on a 24-hour, or circadian, schedule. The up-and-down daily cycles of a long-studied clock protein called Rev-erb coordinates the ebb and flow of gene expression by tightening ...

Drosophila fruit flies are so named after the Latin for "dew loving" because they are more active at dawn and dusk. This strong sense of circadian rhythm (the 24 hour time cycle) is generated by a clock that ticks in the ...
