Too little sleep, disrupted internal clock means higher risk of diabetes and...
A study by researchers at Brigham and Women's Hospital (BWH) reinforces the finding that too little sleep or sleep patterns that are inconsistent with our body's "internal biological clock" may lead to...
View ArticleEnergy levels link sleep control mechanisms
Sleep, or lack of it, can determine level of cognitive performance which is linked with accidents as well as increased risk of serious health problems. Links between cell energy levels, gene...
View ArticleMore than 3,000 epigenetic switches control daily liver cycles
(Medical Xpress)—When it's dark, and we start to fall asleep, most of us think we're tired because our bodies need rest. Yet circadian rhythms affect our bodies not just on a global scale, but at the...
View ArticleStudy finds that a gene associated with longevity also regulates the body's...
Human sleeping and waking patterns are largely governed by an internal circadian clock that corresponds closely with the 24-hour cycle of light and darkness. This circadian clock also controls other...
View ArticleFailure of brain's clock could play role in causing neuropsychiatric disorders
(Medical Xpress) -- Neuropsychiatric disorders are the second largest cause of morbidity and premature mortality worldwide. The scientific community has widely accepted that people who battle...
View ArticleCircadian clock may impact organ transplant success
Health care providers assess blood and tissue type as well as organ size and health to enhance transplant success. New research indicates that checklist might also need to include the circadian clock.
View ArticleLiving against the clock: Does loss of daily rhythms cause obesity?
When Thomas Edison tested the first light bulb in 1879, he could never have imagined that his invention could one day contribute to a global obesity epidemic. Electric light allows us to work, rest and...
View ArticleProbing sleep's drowsy mystery: Researchers stay up nights trying to...
It is one of the ironies of sleep research that scientists stay up all night to do it.
View ArticleCell death in retina helps tune our internal clocks
(Medical Xpress)—With every sunrise and sunset, our eyes make note of the light as it waxes and wanes, a process that is critical to aligning our circadian rhythms to match the solar day so we are...
View ArticleResearcher examines behavior of genes to understand breast cancer risks,...
Most often, people associate circadian rhythms with the symptoms of jet lag that occur after crossing several time zones. Circadian rhythms, which get their cues from light and darkness, can change...
View ArticleDrug blocks light sensors in eye that may trigger migraine attacks
For many migraine sufferers, bright lights are a surefire way to exacerbate their headaches. And for some night-shift workers, just a stroll through a brightly lit parking lot during the morning...
View ArticleResearchers identify key molecular components linking circadian rhythms and...
(Medical Xpress)—Researchers at the University of Cincinnati (UC) have identified key molecular components linking circadian rhythms and cell division cycles in Neurospora crassa, providing insights...
View ArticleStudy seeks connections between sleep and memory consolidation in the cortex
(Medical Xpress)—Neurologists have known that an intrinsic connection exists between the consolidation of memory and neural activity during sleep. Indeed, over the course of the last century,...
View ArticleThe timing of sleep just as important as quantity
Washington State University researchers have found that the timing of an animal's sleep can be just as important as how much sleeps it gets.
View ArticlePowering up the circadian rhythm
At noon every day, levels of genes and proteins throughout your body are drastically different than they are at midnight. Disruptions to this 24-hour cycle of physiological activity are why jet lag or...
View ArticleCould quality of sleep have to do with sex differences?
You may have noticed that women are more prone to sleep disturbances than men. They are, for instance, up to twice as likely to suffer from insomnia than men. Could there be a link between the body...
View ArticleStudy identifies 'night owl' gene variant
If you've been a night owl all your life and mornings are your nemesis, you may be able to blame a gene mutation for all those late nights.
View ArticleSmell sensitivity varies with circadian rhythm, study suggests
It has always been apparent that some individuals have a better sense of smell than others, but a new study of 37 teens provides the first direct evidence that within each person, smell sensitivity...
View ArticleTime matters: Does our biological clock keep cancer at bay?
Our body has an internal biological or "circadian" clock, which cycles daily and is synchronized with solar time. New research done in mice suggests that it can help suppress cancer. The study,...
View ArticleScientists curb growth of cancer cells by blocking access to key nutrients
Salk researchers have discovered how to curb the growth of cancer cells by blocking the cells' access to certain nutrients. The approach, detailed in a new paper published today in Nature, took...
