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

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

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

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.

“Changes in circadian rhythms happen with aging, and evidence suggests that circadian rhythm disturbances may be a risk factor for neurodegenerative diseases like dementia,” said Dr. Wang.

Titled “Role of Cardiac Clock Misalignment in Promoting Arrhythmias in Swine and Donor Human Hearts,” the five-year, $3.4 million study is funded by a R01 grant from the National Heart, Lung and Blood ...

Researchers from the Institute for Molecular Science (IMS)/SOKENDAI and Kyushu University have uncovered the molecular mechanism that drives the "ticking" of the circadian clock in cyanobacteria.
