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 ...

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 ...

Post-translational modifications are as, or even more, important than transcriptional regulation to finely tune circadian rhythms. Oscillations in period (PER) and cryptochrome (CRY) protein abundance ...

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 study opens up the possibility of modifying the circadian clock to control growth and tumour development in plants, and might have applications in biomedicine Biological rhythms are ubiquitous in ...

While bright light helps us see better, our eyes need darkness for better vision. Light breaks down the sensitive machinery of our eyes every day, and during the darkness of night, key pieces are ...

Frequent travelers are only too familiar with the fact that our bodies keep track of time. We may be able to travel across multiple time zones in just a few hours, but our clock keeps ticking to the ...
