Mice with deviant internal rhythms due to a genetic mutation have fewer offspring and shorter life spans than normal conspecifics whose rhythms follow the 24-hr cycle of a day more accurately. This discovery was made by a ...

While our "body clock" regulates our 24 hour daily routine, a woman's menstrual cycle follows a 30 day rhythm. Many marine animals, such as the worm Platynereis, synchronize their reproduction rhythm with the lunar cycle. ...
