A team of researchers have identified a fundamental mechanism that links the 24-hour circadian cycle to the precise repair of ...

Circadian rhythm, a natural cycle that regulates many biological processes, operates on a 24-hour cycle. Changes in light and dark significantly impact circadian cycles, and abnormalities can disrupt ...

Researchers have advanced our understanding of the circadian clock, the biological cycle that synchronizes with light-dark exposure. They recently developed a method to study how the circadian clock ...

Researchers discovered that more than 300 liver genes are under circadian control: Circadian variations affect how much of a drug is available and how effectively the body can break it down. Giving ...

Cluster headache and migraine have strong ties to the circadian system at multiple levels, new findings that could have significant treatment implications. A meta-analysis of 16 studies showed a ...

Asthma often worsens at night. To determine if the endogenous circadian system contributes to the nocturnal worsening of asthma, independent of sleep and other behavioral and environmental day/night ...
