Twice a year we change our clocks by an hour, with Daylight Saving Time sending the clocks back an hour in spring, and ending when the clocks go forward an hour in the fall to return us to Standard ...

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

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 study reveals that weaker circadian rhythms may significantly increase the risk of developing dementia in older adults.

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 ...

"Disruptions in circadian rhythms may alter body processes like inflammation, and may interfere with sleep, possibly increasing amyloid plaques linked to dementia, or reducing amyloid clearance from ...
