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 ...

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 ...

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 ...

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 ...

The season in which babies are born can have a dramatic and persistent effect on how their biological clocks function. That is the conclusion of a new study published online on Dec. 5 by the journal ...

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 ...

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 ...
