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 clock for nocturnal activity
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…
New guidelines to ease sleepless nights
London, UK (September 2, 2010) — Insomnia and other sleep disorders are very common, yet are not generally well understood by doctors and other health care professionals. Now the British Association for Psychopharmacology (BAP) has released up-to-…
Light, circadian rhythms affect vast range of physiological, behavioral functions
CORVALLIS, Ore. — A new study of the genetic basis of circadian rhythms — the biological responses related to daily light exposure — has found that a few minutes of light exposure in a fungus directly affects a huge range of its biological f…
