. But mice fed a fatty diet have trouble sticking to their schedule, new research shows.

fails to synchronize appropriately with Earth's day-night cycle, which changes a few minutes each day.
To make this discovery, Coomans and colleagues exposed mice to constant light, which disturbed their normal internal clock
function, and observed a gradual degradation of their bodies' internal clocks
until it reached a level that normally occurs when aging.
One theory has it that such long-term growth cycles operate on an internal clock
that's independent of the seasons or temperature.
Washington, January 18 ( ANI ): New research has shown how the fruit fly's internal clock
is affected by the daily changes in temperature.
That was your internal clock
