Night-shift workers face an increased risk of obesity and diabetes, but the underlying reason for that has been a mystery. Now, University of Missouri School of Medicine researchers have found a potential cause for metabolic changes during night-shift work that creates confusion between cells in the body and the central clock in the brain. “We

While most of us dream of a slow morning with sunshine streaming through the windows and birds chirping outdoors, reality looks more like an obnoxious-sounding alarm clock blaring through the darkness. Thankfully, science has provided the perfect alternative for anyone in a constant battle with their alarm clock: the Philips Wake-Up Light Alarm Clock ($90,

New research has found it is not just what you eat, but when you eat that is important, knowledge which could improve the health of shift workers and people suffering from jet lag. The Medical Research Council (MRC)-funded study, published today in the journal Cell, is the first to identify insulin as a primary signal

Admission to hospital with a heart attack outside normal working hours does not appear to increase a patient’s chance of dying in hospital, according to a study of more than 600,000 patient cases. The new research suggests that fears about potential differences in outcomes depending on the time of hospital admission may be unfounded. Led

A new drug shows potential to halt cancer cells’ growth by stunting the cells’ biological clock. The findings from scientists at the USC Michelson Center for Convergent Bioscience and Nagoya University’s Institute of Transformative BioMolecules (ITbM) advance a burgeoning area of research: turning the body’s circadian rhythms against cancer. Their study, conducted on human kidney

The first simple blood test to identify your body’s precise internal time clock as compared to the external time has been developed by Northwestern Medicine scientists. The test, TimeSignature—which requires only two blood draws—can tell physicians and researchers the time in your body despite the time in the external world. For instance, even if it’s

Could this be a cure for insomnia? How a sleep mask can send out a ‘camera flash’ of light to reset the clock for night owls A new, high-tech sleep mask sends out millisecond pulses of light as you sleep The pulses stimulate nerves that are sensitive to light and that help produce melatonin, the

Your brain has a clock counting down the seconds until it’s time to go to sleep Proteins in the brain track synaptic activity, acting like a count down clock Chemical tags gather on these proteins throughout the day and fall off at night Researchers at the University of Texas say that these maintain wake-sleep balance
