New UC Davis research shows how an internal circadian clock controls the opening of individual florets in concentric rings in the sunflower head. This helps attract pollinating insects. (Jason Spyres) ...

Circadian clocks control physiological processes and behavior in virtually all living organisms. Now an international research team has created a detailed map of the internal clock in the brain of the ...

Ketone bodies are energy-rich metabolites and signaling molecules whose production is mainly regulated by diet. Caloric restriction (CR) is a dietary intervention that improves metabolism and extends ...

New understanding of circadian rhythms could be key to stronger, drought-resistant crops in the face of climate change. The biological clock of a popular food crop controls close to three-quarters of ...

The circadian clock system (from the Latin "circa diem," about a day) allows organisms to anticipate periodic changes of geophysical time and to adjust to those changes. Nearly all cells comprise ...

All animals including humans are subject to daily rhythms in their activity and sleep, hunger, metabolism, and reproduction. The system that regulates these biological rhythms is known as the ...
