The human body clock is the curse of any shift worker or traveler arriving in a new time zone. Although one's body clock can be adjusted by external cues, such as light – a factor that devices such as ...

Researchers have discovered a new mechanism that governs how body clocks react to changes in the environment. The discovery could provide a solution for alleviating the detrimental effects of chronic ...

The activation and inactivation mechanisms of a key protein involved in the circadian clock system of cyanobacteria -- an important organism in the evolution of such internal clocks -- have long ...

Molecular clocks in our cells synchronize our bodies with the cycle of night and day, cue us for sleep and waking, and drive daily cycles in virtually every aspect of our physiology. Scientists ...

The circadian clock in cyanobacteria represents one of the most elegant and thoroughly studied biological timekeeping systems. This oscillator is principally driven by the concerted actions of Kai ...

A new study of molecular interactions central to the functioning of biological clocks explains how certain mutations can shorten clock timing, making some people extreme “morning larks” because their ...
