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 ...

Research into genetic mutations that affect circadian rhythms offers new insight into the rest-wake cycle and provides a new model for investigating human disease and ultimately developing medical ...

Every cell in the human body operates on an intricate internal schedule, governed by circadian rhythms that synchronize our biological processes with the 24-hour cycle of day and night. Coordinated by ...

A research collaboration between the Faculty of Biochemistry and Molecular Medicine at the University of Oulu, Finland, the University of Innsbruck, Austria, and Florida Tech, USA, explored the ...

Aichi, Japan--Researchers from the Institute for Molecular Science (IMS)/SOKENDAI and Kyushu University have uncovered the molecular mechanism that drives the "ticking" of the circadian clock in ...

It has been known for years that the brains of many organisms incorporate a "circadian clock" — a biological time-keeping mechanism that connects the body's rhythms to external light levels. The clock ...

(PhysOrg.com) -- Scientists have long known that interrupting the 24-hour circadian rhythm plays havoc with the lives and health of medical, military and airline personnel, factory employees and ...
