Scientists Find the Tiny 24-Hour Clock in Every Living Thing

[Gerald]

Scientists have identified the mechanism that controls the internal 24-hour clock of all forms of life -- from us to algae.

Researchers from Britain's Cambridge and Edinburgh universities, whose work was published in the journal Nature on Wednesday, said their findings provide important insight into health-related problems linked to people such as nurses, pilots and other shift workers, whose body clocks are disrupted.

The studies also suggest that the 24-hour circadian clock found in human cells is the same as that found in algae, and dates back millions of years to early life on earth, they said.
