Biologists have uncovered one way that biological clocks control neuronal activity -- a discovery that sheds new light on sleep-wake cycles and offers potential new directions for research into ...

The molecular pathway that carries time-of-day signals from the body's internal clock to ultimately guide daily behavior is like a black box, says a researcher. Now, new research is taking a peek ...

Humans and most other organisms have internal biological clocks that track the daily cycle of sunrise and sunset. These clocks help time our sleep, metabolism and other essential body functions over ...

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 ...

Pregnant women rely on a balanced diet and supplements to deliver proper nutrients to their babies, to ensure they grow healthfully. Such nutrients contribute to fueling development and providing ...
