Almost all living things have an internal 24-hour clock that remains accurate regardless of temperature or other ...

Researchers have advanced our understanding of the circadian clock, the biological cycle that synchronizes with light-dark exposure. They recently developed a method to study how the circadian clock ...

The "master clock" in the suprachiasmatic nucleus (SCN) of the hypothalamus controls most behavioral, physiological, and molecular circadian rhythms in mammals. However, there are other, still ...

Daily cycles in virtually every aspect of our physiology are driven by biological (or circadian) clocks in our cells. A team of interdisciplinary scientists has now reconstituted the circadian clock ...

This illustration shows how the components of the cyanobacterial circadian clock interact in a 24-hour cycle. (Image credit: Andy LiWang) Daily cycles in virtually every aspect of our physiology are ...

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.

In a study published May 28 in the journal npj Digital Medicine, University of Michigan researchers found that individuals with stronger seasonal sensitivity, which determines how a person’s body ...

The combination of mathematical modeling and experiments identifies the difference in molecular clockworks of the master and slave clock neurons in Drosophila. This solves the long-standing mystery of ...

Chemical oscillators have long been studied by engineers and scientists. The researchers who discovered the chemical oscillator that controls the human circadian rhythm — responsible for our bodies’ ...

As our bodies and minds continue to adjust to the recent time change, debates continue around society about whether to make daylight saving time a permanent fixture, eliminate it or stay with the ...
