A light touch changes the biological clock

Airline passengers leaving San Francisco for London might one day use a precisely timed dose of light to reset their biological clocks to English time and avoid debilitating jet lag, if future research confirms a study reported this week.

Scientists have just begun unraveling the complicated circadian rhythm that governs sleepiness, hormone levels and other daily cycles of the body. Three years ago, researchers in Bost...

A light touch changes the biological clock.
Science News ; A light touch changes the biological clock Airline passengers leaving San Francisco for London might one day use a precisely timed dose of light to reset their biological clocks to English time and avoid debilitating jet lag, if future research confirms a study reported this week. Scientists have
Timely surprises: biological clocks sense light in obscure ways.(includes related article on biological clock components)
Science News ; When a New Yorker jets off to Los Angeles or Tokyo, it takes just a few seconds to adjust a wristwatch to local time. But as sufferers of jet lag know all too well, the body's internal clock isn't nearly so quick to adapt. It usually takes a few days for a person's biological clock to synchronize
That biological clock keeps on ticking
Resource ; Temperature may be a cue for setting the biological clocks that govern the daily ebb and flow of activity in most animals and plants, Dartmouth Medical School (DMS) geneticists have found. Their work advances understanding of how internal clocks keep time over the wide range of environmental
Knee may be key to humans' biological clock, study suggests Expert calls finding so surprising that it's `revolutionary'
The Milwaukee Journal Sentinel ; In an experiment from the strange but possibly true category, scientists have shone a bright light on the backs of human knees and, in some mysterious way, reset the master biological clock in the human brain. Those treated with the light had their biological clocks advanced or delayed up to three
Protein may help the eyes tell time.(study of the African hornerd frog may help determine the workings of mammals' biological clocks)(Brief Article)
Science News ; The light-sensitive skin cells of the African horned frog may have resolved a lingering mystery about the internal biological clock that all mammals possess, suggests a new study. This physiological timepiece, whose period is almost exactly a day, governs many bodily rhythms. To synchronize with
There are no guarantees with biological clocks
Chicago Sun-Times ; Before Rolex, before Mickey Mouse, before John Cameron Swayze put Timex watches on spinning motorboat propellers, there were biological clocks. We didn't talk much about them. We just knew they ticked away our youth and one day they stopped. Some of us realized something else about biological
Researchers Discover Plants' Biological Clock; Gene May Have Health, Agricultural Uses
The Washington Post ; Scientists who created glow-in-the-dark plants by shooting up seedlings with firefly DNA have identified the first biological clock gene in plants. Discovery of the timepiece gene, which controls such biological rhythms as daily leaf movements and pore openings, flower-blooming schedules and
Biological clocks fly into view. (Scripps researcher Steve A. Kay found that the several of the fruit fly's organs are sensitive to circadian rhythms and light)(Brief Article)
Science News ; Clocks are ubiquitous in today's society. In addition to their traditional homes on mantles, nightstands, and wrists, timepieces now appear on VCRs, computer screens, TVs, microwave ovens, and much more. Nature's fondness for clocks may be even more impressive, however. Scientists report in the
Lighting up biological clocks; genes from glowing organisms illuminate circadian rhythms.
Science News ; In the ocean, the brownish, single-celled alga Gonyaulax polyedra puts on an unusual light show. At night, it glows softly and emits bright flashes from time to time. But during the day, when these organisms aggregate near the ocean's surface and use sunlight to make needed chemicals through
Scientists Identify What Makes a Mouse's Biological Clock Tick
The Washington Post ; Scientists are much closer to understanding the causes of a host of maladies, from jet lag and shift-work problems to sleep disorders related to aging, thanks to striking new research on the brain's "biological clock" -- the tiny but hugely mysterious aggregation of cells that dictates the body's
