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 ...

A recent report in Cell shows that the transcription and translation cycles that drive the molecular circadian clock may also be regulated by electrical activity. Despite our extensive knowledge about ...

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 ...

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 ...

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 ...

If you've ever had a bad case of jet lag, you know how a disruption to your body's circadian rhythm makes it difficult to function. Molecular circadian "clocks" exist in cells throughout the body, ...

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 ...
