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) ...

Time may feel smooth and continuous, but at the quantum level it behaves very differently. Physicists have now found a way to measure how long ultrafast quantum events actually last, without relying ...

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 ...

University of Queensland-led research has revealed liver cells influence the body’s internal circadian clock, which was previously believed to be solely controlled by the brain. Associate Professor ...

You go to bed at the same time every night but still feel exhausted in the morning. You crash at 3 PM daily despite getting eight hours of sleep. You lie awake staring at the ceiling when you should ...

“In a prior [human] study, we found that when behavior cycles of feeding and sleeping are not in normal alignment with the internal body clock, that this negatively affects the regulation of blood ...

An internal circadian clock controls the distinctive concentric rings of flowering in sunflowers, maximizing visits from pollinators, a new study from plant biologists at the University of California, ...
