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 ...

Between work schedules and jet lag, there are a number of things that can throw off your body’s natural light-dark cycle. “Your circadian rhythm is a natural, biologic cycle that sets when your brain ...

Your daily rhythm may matter more for brain health than previously thought. Older adults with weaker, more disrupted activity ...

Biological rhythm is a phrase often used interchangeably with circadian rhythm. These rhythms are a series of bodily functions regulated by your internal clock. They control cycles like sleepand ...

The inner-workings of the "circadian clock" are complex. The molecular processes behind it have eluded scientists until now. Two new studies from June 2013 have uncovered specific proteins that drive ...

Scientists at the Johns Hopkins University School of Medicine and the National Institutes of Health have identified a protein in the visual system of mice that appears to be key for stabilizing the ...

Studies by scientists at Rensselaer Polytechnic Institute have found that the brain’s ability to clear a protein that builds up in the brains of patients with Alzheimer’s disease (AD) is tied to our ...

Alzheimer's disease is notorious for scrambling patients' daily rhythms. Restless nights with little sleep and increased napping during the day are early indicators of disease onset, while sundowning, ...

The fruit fly circadian cycle shares three strong similarities with the mammalian: the per gene itself, CLOCK and BMAL regulation of per, and a gene called tau in hamsters and double-time (dbt) in ...

Mice that eat during the active phase of their daily circadian cycle burn more calories through enhanced thermogenesis, mitigating the development of obesity, researchers report. The findings help ...
