WINTHROP, N.Y. – Above an auto garage in this town near the Canadian border, there is a large gilt clock dial from a different era. Behind its facade, there lies a clock mechanism comprising an ...

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 ...

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 Nobel Prize in Physiology or Medicine was awarded today to Jeffrey C. Hall, Michael Rosbash and Michael W. Young for discoveries of molecular mechanisms controlling circadian rhythms. Following ...

Mystery clocks have been popular since the 18th century. The clock seems to have no mechanism but keeps time. One of the most famous is the swinging-arm clock. A tall classical figure, usually bronze, ...

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 ...

Living organisms, from plants to fungi to animals, have a circadian rhythm – a 24 hour cycle of physiological events. New findings have elucidated more about how these natural clocks are related to ...

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 ...

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 ...
