Circadian ‘snooze button’ improves cell adaptability

The circadian clocks that control and influence dozens of basic biological processes have an unexpected "snooze button" that helps cells adapt to changes in...

WSU researchers apply fatigue model to fatal commuter air crash

SPOKANE, Wash. -- Washington State University sleep researchers have determined that the air traffic controller in the crash of a Lexington, Ky., commuter flight was substantially fatigued when he failed to detect that the plane was on the wrong r...

UNC scientists pinpoint link between light signal and circadian rhythms

Chapel Hill, NC -- In a new paper published this week in the Proceedings of the National Academy of Sciences, Aziz Sancar, MD, PhD, the Sarah Graham Kenan Professor of Biochemistry and Biophysics in the UNC School of Medicine, and his colleagues ha...

Breakthrough in worm research has implications for human disease studies

RENO, Nev. -- It's just a worm, a tiny soil-dwelling nematode worm -- but the implications are big for biomedicine and circadian biology as shown in a recent study authored by University of Nevada, Reno researcher Alexander van der Linden. The art...

Plant clock gene also works in human cells

A gene that controls part of the 'tick tock' in a plant's circadian clock has been identified by UC Davis researchers. And not only is the plant gene very similar to one in humans, but the human gene can work in plant cells -- and vice versa. The re...

Scientists clock on to how sunlight shapes daily rhythms

Fresh insight into how biological clocks adjust to having less sunlight in the winter could help us better understand the impact of jet lag and shift work. Scientists studying the daily activity cycle in plants -- known as circadian rhythms -- h...

Internal body clock controls fat metabolism, UCI study shows

Irvine, Calif., Nov. 15, 2010 -- UC Irvine researchers have discovered that circadian rhythms -- the internal body clock -- regulate fat metabolism. This helps explain why people burn fat more efficiently at certain times of day and could lea...

Scripps Research scientists identify new mechanism regulating daily biological rhythms

JUPITER, FL, November 9, 2010 -- For Immediate Release -- Scientists from the Florida campus of The Scripps Research Institute have identified for the first time a novel mechanism that regulates circadian rhythm, the master clock that controls the...

Temperature rhythms keep body clocks in sync, UT Southwestern researchers find

DALLAS -- Oct. 14, 2010 -- Researchers at UT Southwestern Medical Center have found that fluctuations in internal body temperature regulate the body's circadian rhythm, the 24-hour cycle that controls metabolism, sleep and other bodily functions. ...

Moonstruck primates: Owl monkeys need moonlight as much as a biological...

PHILADELPHIA -- - An international collaboration led by a University of Pennsylvania anthropologist has shown that environmental factors, like temperature and light, play as much of a role in the activity of traditionally nocturnal monkeys as...
