New paper describes connections between Circadian and metabolic systems
A paper by University of Notre Dame biologist Giles Duffield and a team of researchers offers new insights into a gene that plays a key role in modulating the body's Circadian system and may also simultaneously modulate its metabolic system. view more (2009-11-13)
Faulty body clock may make kids bipolar
Malfunctioning circadian clock genes may be responsible for bipolar disorder in children. Researchers writing in the open access journal BMC Psychiatry found four versions of the regulatory gene RORB that were associated with pediatric bipolar disorder. view more (2009-11-12)
Java and nighttime jobs don't mix: study
Night-shift workers should avoid drinking coffee if they wish to improve their sleep, according to research published in the journal Sleep Medicine. view more (2009-11-04)
Hydrogen Peroxide's Link to Living Cells
If a circadian rhythm is like an orchestra - the united expression of the rhythms of millions of cells - a common chemical may serve as the conductor, or at least as the baton. view more (2009-11-04)
Circadian surprise: A heat sensor for body-clock synchronization
New research on the fruit-fly brain points to a possible mechanism by which temperature influences the body clock, according to scientists from Queen Mary, University of London. view more (2009-10-30)
Whales are polite conversationalists
What do a West African drummer and a sperm whale have in common? According to some reports, they can both spot rhythms in the chatter of an ocean crowded with the calls of marine mammals -- a feat impossible for the untrained human ear. view more (2009-10-27)
Texas A&M researchers find new mechanism for circadian rhythm
Molecules that may hold the key to new ways to fight cancer and other diseases have been found to play an important role in regulating circadian rhythm, says Liheng Shi, a researcher in Texas A&M's Department of Veterinary Integrative Biosciences. view more (2009-10-21)
The food-energy cellular connection revealed
Our body's activity levels fall and rise to the beat of our internal drums-the 24-hour cycles that govern fundamental physiological functions, from sleeping and feeding patterns to the energy available to our cells. view more (2009-10-16)
Scientists reveal new pattern in our daily clock
The findings of a study published in Science today turn a long-held theory on circadian rhythms on its head and mean that we may now be able to develop new drugs and approaches to tune the daily clock to treat sleep disorders and to aid recovery from long-distance flights. view more (2009-10-09)
U-M discovery about biological clocks overturns long-held theory
University of Michigan mathematicians and their British colleagues say they have identified the signal that the brain sends to the rest of the body to control biological rhythms, a finding that overturns a long-held theory about our internal clock. view more (2009-10-09)
How would Einstein use e-mail?
You're not as different from Albert Einstein and Charles Darwin after all, at least when it comes to patterns of correspondence. view more (2009-09-28)
Half of eligible patients not getting mitral valve surgery, U-M study shows
Overblown fears about surgical risk and lack of awareness about the risk of not operating are among the reasons only half of eligible patients were referred for mitral valve repair, according to a study by doctors at the University of Michigan Cardiovascular Center. view more (2009-09-11)
WUSTL research finds individual cells isolated from the biological clock can keep daily time, but are unreliable
Alexis Webb enters a small room at Washington University in St. Louis with walls, floor and ceiling painted dark green, shuts the door, turns off the lights and bends over a microscope in a black box draped with black cloth. Through the microscope, she can see a single nerve cell on a glass cover slip glowing dimly. view more (2009-09-10)
Chemotherapy for breast cancer is associated with disruption of sleep-wake rhythm in women
A study in the Sept.1 issue of the journal Sleep shows that the sleep-wake activity rhythms of breast cancer patients are impaired during the administration of chemotherapy. view more (2009-09-01)
Caltech researchers pinpoint neurons that control obesity in fruit flies
A team of scientists from the California Institute of Technology (Caltech) have pinpointed two groups of neurons in fruit fly brains that have the ability to sense and manipulate the fly's fat stores in much the same way as do neurons in the mammalian brain. view more (2009-08-19)
First human gene implicated in regulating length of human sleep
Scientists have discovered the first gene involved in regulating the optimal length of human sleep, offering a window into a key aspect of slumber, an enigmatic phenomenon that is critical to human physical and mental health. view more (2009-08-14)
Biological clocks of insects could lead to more effective pest control
Researchers at Oregon State University have discovered that the circadian rhythms or biological "clocks" in some insects can make them far more susceptible to pesticides at some times of the day instead of others. view more (2009-08-13)
Plants' internal clock can improve climate-change models
The ability of plants to tell the time, a mechanism common to all living beings, enables them to survive, grow and reproduce. view more (2009-07-06)
New therapy found to prevent heart failure
A landmark study has successfully demonstrated a 29 percent reduction in heart failure or death in patients with heart disease who received an implanted cardiac resynchronization therapy device with defibrillator (CRT-D) versus patients who received only an implanted cardiac defibrillator (ICD-only). view more (2009-06-24)
Genetic pathway responsible for link between body clock disturbance and worsening arthritis
The genes that regulate human circadian rhythm, or 'the body clock', are significantly disturbed in individuals with arthritis. view more (2009-06-11)
