Molecular clocks in our cells synchronize our bodies with the cycle of night and day, cue us for sleep and waking, and drive daily cycles in virtually every aspect of our physiology. Scientists ...

Biological rhythms are ubiquitous in nature, from the beating of the heart to the rhythms of flowering plants. A research team has shown that the two main cellular oscillators -- the circadian clock ...

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 ...

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 ...

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 ...

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 ...

We've already nudged you this week about the benefits of breakfast. And this got us thinking more about the timing of our meals. There's a growing body of evidence to suggest that when we eat during a ...

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 ...

Recent data suggest that the circadian clock regulates cognitive functions such as memory and mood in a sleep-dependent and sleep-independent manner. Some circadian clock proteins are important ...
