Astrocytes prove to be surprisingly vital players in the body's clock

Until recently, work on biological clocks that dictate daily fluctuations in most body functions, including core body temperature and alertness, focused on neurons, those electrically excitable cells that are the divas of the central nervous system.

Timing of carbohydrate intake plays role in blood glucose regulation for men with prediabetes

According to a nutrition study led by the German Institute of Human Nutrition, a partner of the German Center for Diabetes Research, the so-called internal clock also influences how people with impaired glucose metabolism react to carbohydrate-rich food.

A new study suggests that the melatonin content of dietary supplements often varies widely from what is listed on the label.

Workplace-based sleep health program can reduce injuries and disability in firefighters

Many firefighters suffer acute and chronic sleep deficiency and misalignment of their circadian rhythm (body clock) due to extended shifts and long work weeks.

Johns Hopkins scientists find link between sleep/wake cycles and core body temperature

A clump of just a few thousand brain cells, no bigger than a mustard seed, controls the daily ebb and flow of most bodily processes in mammals -- sleep/wake cycles, most notably.

New study explores circadian timekeeping to create genetic knock-out rescue mice

A new study from the laboratory of Hiroki Ueda at the RIKEN Quantitative Biology Center investigates circadian timekeeping with a novel approach to creating genetic knock-out rescue mice.

TSRI scientists unravel mystery of ‘food coma’ phenomenon

Anyone who has drifted into a fuzzy-headed stupor after a large holiday meal is familiar with the condition commonly known as a "food coma."

Researchers identify mechanism of how circadian clocks in neurons encode daily rhythms of excitability

Molecular clocks in cells throughout the body control many physiologic changes in a 24-hour day/night circadian rhythm -- among them the timing of sleep and wakefulness.

Particular eating behaviors linked to lower odds of developing liver diseases

Particular eating behaviors may lower the risk of developing non-alcoholic fatty liver disease (NAFLD), according to research presented this week at The Liver Meeting — held by the American Association for the Study of Liver Diseases.

New study examines genetic factors underlying poor tolerance to shift work

Some people adapt easily to shift work, but not everyone can handle constant disruptions to their daily rhythm. Finnish researchers have now found that a melatonin receptor gene influences tolerance to shift work.

New technology may help scientists better understand circadian rhythm in individual cells

An interdisciplinary team of researchers at the University of Georgia has developed a new technology that may help scientists better understand how an individual cell synchronizes its biological clock with other cells.

Disrupted circadian rhythm may not help achieve maximum weight loss after bariatric surgery

A newly released basic science study of Roux-en-Y gastric bypass (RYGB) suggests that a functioning circadian clock, or sleeping at night and being awake during the day, can help patients achieve a higher amount of weight loss following the surgery.

Study provides insight into how the brain's biological clock regulates physiological function

The brain's biological clock stimulates thirst in the hours before sleep, according to a study published in the journal Nature by McGill University researchers.

Studies find night shift work has little or no effect on woman's breast cancer risk

Despite an assessment in 2007 indicating that night shift work was probably carcinogenic, data from three new studies and from a review of currently available evidence, published in the Journal of the National Cancer Institute, indicate that night shift work has little or no effect on breast cancer incidence.

Review examines link between insomnia and alcohol dependence

Individuals with alcohol dependence (AD) often have sleep-related disorders such as insomnia, circadian-rhythm sleep disorders, breathing-related sleep disorders, movement disorders, and parasomnias such as sleep-related eating disorder, sleepwalking, nightmares, sleep paralysis, and REM sleep behavior disorder.

High cortisol levels during morning sessions provide more benefits to psychotherapy patients

Patients make more progress toward overcoming anxiety, fears and phobias when their therapy sessions are scheduled in the morning, new research suggests.

Research highlights interaction between biological clock and sleep loss at regional brain level

Ever wondered what happens inside your brain when you stay awake for a day, a night and another day, before you finally go to sleep? In a new study published today in the journal Science, a team of researchers from the University of Liege and the University of Surrey have scanned the brains of 33 participants across such a 2-day sleep deprivation period and following recovery sleep.
