(PhysOrg.com) -- Most everyone has heard of the circadian rhythm or the internal clock that people have that tells them when to do things, such as go to sleep. In fact, researchers have actually located where this “clock” ...
Biologists have long known that organisms from bacteria to humans use the 24 hour cycle of light and darkness to set their biological clocks. But exactly how these clocks are synchronized at the molecular level to perform ...

Dieticians will tell you it isn't healthy to eat late at night: it's a recipe for weight gain. In fruit flies, at least, there's another consequence: reduced fertility.
