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 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 mammalian circadian clock consists of a transcription–translation feedback loop (TTFL) composed of CLOCK–BMAL1 transcriptional activators and CRY–PER transcriptional repressors. Previous work ...

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 ...

Researchers have identified a key mechanism involved with the setting of the circadian clock of cyanobacteria—a model organism for study by chronobiologists due to the organism having one of the ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 116, No. 46 (November 12, 2019), pp. 23339-23344 (6 pages) Drosophila CRYPTOCHROME (dCRY) mediates ...

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 ...

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 ...
