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 ...

The familiar tick-tock of wall clocks originates from the escapement mechanism, which controls gear movement in precise steps ...

The tick-tick sound comes from the movement of gears and parts inside the clock. In mechanical clocks, a part called the ...

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 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 ...

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 ...
