Differences in jet lag severity could be rooted in how circadian clock sets itself
It's no secret that long-distance, west-to-east air travel Seattle to Paris, for example can raise havoc with a person's sleep and waking patterns, and that the effects are substantially less pronounced when ...
Circadian cycle even more important to life than previously suspected: study
Researchers at USC were surprised recently to discover just how much the rising and setting of the sun drives life on Earth even in unexpected places.
Circadian clocks in a blind fish
Do animals that have evolved for millions of years underground, completely isolated from the day-night cycle, still "know" what time it is? Does a normal circadian clock persist during evolution under constant darkness? A ...
Glowing, blinking bacteria reveal how cells synchronize biological clocks
Biologists have long known that organisms from bacteria to humans use the 24 hour cycle of light and darkness to set their biological clocks. But exactly how these clocks are synchronized at the molecular level to perform ...
Manipulating plants' circadian clock may make all-season crops possible
Yale University researchers have identified a key genetic gear that keeps the circadian clock of plants ticking, a finding that could have broad implications for global agriculture.
Finding mechanism behind bacteria's biological clock
(PhysOrg.com) -- A discovery by a professor at the University of California, Merced, is providing a deeper understanding of the factors that control biological clocks.
Repairing our inner clock with a two-inch fish
Circadian rhythms the natural cycle that dictates our biological processes over a 24-hour day does more than tell us when to sleep or wake. Disruptions in the cycle are also associated with depression, problems ...
Biologists discover an 'evening' protein complex that regulates plant growth
Farmers and other astute observers of nature have long known that crops like corn and sorghum grow taller at night. But the biochemical mechanisms that control this nightly stem elongation, common to most plants, have been ...
Newly discovered molecule essential to resetting 'body clocks'
(PhysOrg.com) -- Research has shown that light is the key to getting our 'body clocks' back in sync and now a new study exploring the resynchronisation mechanism in insects has discovered a molecule essential ...
'Wrong'-time eating reduces fertility in fruit flies
Dieticians will tell you it isn't healthy to eat late at night: it's a recipe for weight gain. In fruit flies, at least, there's another consequence: reduced fertility.
Video gaming teens sleep less: study
Teens who play a lot of video games are likely to sleep less than the eight to nine hours a night recommended for the age group, researchers said Monday.
Circadian rhythms spark plants' ability to survive freezing weather
Just as monarch butterflies depend on circadian cues to begin their annual migration, so do plants to survive freezing temperatures.
Experimental work proves theory that circadian body clock requires delay to function properly
For more than 20 years, theoretical mathematical models have predicted that a delay built into a negative feedback system is at the heart of the molecular mechanism that governs circadian clocks in mammalian ...
'Round-the-clock' lifestyle can disrupt metabolism, brain and behavior
(PhysOrg.com) -- In Civilization and Its Discontents, Sigmund Freud argued that modern society was hard on human psychology, forcing people to get along in unnaturally close quarters. Now newly published resear ...
