Weizmann Institute researchers say that progesterone and the stress hormone cortisol drive circadian rhythms; when out of ...

The results of a recent study suggest that people with a weaker or more irregular body clock, also known as circadian rhythm, ...

Your daily rhythm may matter more for brain health than previously thought. Older adults with weaker, more disrupted activity patterns were far more likely to develop dementia than those with steady ...

In the study published in the Annals of Behavioral Medicine, the researchers set out to determine the health impacts of everyday physical activities, including walking regularly and doing chores. The ...

Muscle cells contain their own circadian clocks and disrupting them with shift work can have a profound impact on aging, according to the results of a preclinical study carried out by Jeffrey Kelu, ...

A time-lapse movie of a WT cyanobacteria strain in a Green Mother Machine. The strain expresses a pkaiBC:eYFP:fsLVA transcriptional reporter (shown in green), which displays circadian oscillations.

Researchers led by Gen Kurosawa at the RIKEN Center for Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS) in Japan have used theoretical physics to discover how our biological clock ...

Many studies suggest that planned, structured exercise, rather than casual activity, may slow epigenetic aging — changes in DNA that reflect biological rather than chronological age. Experiments in ...
