Circadian clocks ensure that we modulate our physiological behaviors, like sleeping and eating, in a rhythmic, 24-hour cycle. They are present in all living cells, from cyanobacteria to humans. The ...

Most biochemical reactions accelerate as temperature increases, but our daily circadian rhythms, which are underlain by gene regulatory and biochemical networks, remain constant, even as temperatures ...

A new study reports that the circadian clock gene BMAL1 and the cell cycle checkpoint regulator WEE1 are significantly ...

When you eat may be just as vital to your health as what you eat, found researchers at the Salk Institute for Biological Studies. Their experiments in mice revealed that the daily waxing and waning of ...

In addition to the sleep–wake cycle and cognitive functions such as learning and memory, intrinsic clocks determine nearly all circadian cycles in physiology, such as daily variation in blood pressure ...

Scientists want to increase their understanding of circadian rhythms, those internal 24-hour biological clock cycles of sleeping and waking that occur in organisms, ranging from humans to plants to ...

It's well known that the human body functions on a 24-hour, or circadian, schedule. The up-and-down daily cycles of a long-studied clock protein called Rev-erb coordinates the ebb and flow of gene ...

All life on Earth has evolved to cope with a rotating planet which results in the predictable transition between day and night. The details differ between plants, fungi, bacteria, and animals, but the ...
