Epigenetic aging clocks use DNA methylation patterns to measure biological age and predict health risks across human tissues.

Daily cycles in virtually every aspect of our physiology are driven by biological clocks (also called circadian clocks) in our cells. The cyclical interactions of clock proteins keep the biological ...

What time is your body clock set on? The answer, mounting research suggests, can influence everything from your predisposition to diabetes, heart disease and depression to the optimal time for you to ...

Sleep researchers have found it's possible to determine the timing of a person's internal biological clock via a single blood draw. Ultimately, the findings could lead to a simple blood test for ...

A digital version of the classic clock-drawing test can accurately identify early Alzheimer's disease (AD) pathology in asymptomatic patients in less than 5 minutes, new research shows. Investigators ...
