New research suggests that mood swings in bipolar disorder are regulated by two clocks: the body’s 24-hour circadian rhythm ...

Your circadian rhythm is your body’s natural way of keeping to its 24-hour body clock, helping your body operate on a healthy sleep-wake schedule. A healthy, active lifestyle that promotes ...

Circadian oscillation of biological processes has been described in most of the light-sensitive organisms on earth. It ...

Cyanobacteria, a group of photosynthetic bacteria, possess a sophisticated circadian clock that regulates their biological processes in a rhythmic manner over a 24-hour cycle. This clock is ...

Objectives The circadian clocks are internal timing mechanisms that drive ∼24-hour rhythms in a tissue-specific manner. Many aspects of the physiology of the intervertebral disc (IVD) show clear ...

The modulating signal then comes from the bacteria's 24-hour circadian clock, which acts as an internal time-keeping mechanism. This finding answers a long-standing question in cell biology—how ...

Many bodily functions, including sleep and digestion, are influenced by your circadian rhythm. This 24-hour cycle, which is ...

The system that regulates these biological rhythms is known as the circadian clock. It controls all processes in the body within a 24-hour period. In vertebrates, the "master" clock is found in ...

Each of these can individually contribute to introduce the delay that keeps the period at ∼24 hours. Figure 3: Multiple roles of casein kinase I in the mammalian circadian clock. Throughout the ...

enables organisms to respond to rhythmic environmental changes occurring over 24 hours. The master circadian clock located in the brain regulates several peripheral clocks in different tissues ...
