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 ...

Older adults with weak 24-hour rest-activity rhythms face roughly 2.5 times the risk of developing dementia compared with those whose internal clocks run strong, according to converging evidence from ...

Bacteria make up more than 10% of all living things but until recently we had little realization that, as in humans, soil bacteria have internal clocks that synchronize their activities with the ...

The Earth has rhythm. Every 24 hours, the planet pirouettes on its axis, bathing its surface alternately in sunlight and darkness. Organisms from algae to people have evolved to keep time with the ...

In life, timing is everything. However, reading one’s internal clock precisely enough remains a major challenge in sleep and circadian health. The current approach requires taking hourly samples of ...
