Universal Signaling Pathway Found To Regulate Sleep

Sleeping worms have much to teach people, a notion famously applied by the children's show "Sesame Street," in which Oscar the Grouch often reads bedtime stories to his pet worm Slimy. Based on research with their own worms, a team of neurobiologists at Brown University and several other institutions has now found that "Notch," a fundamental signaling pathway found in all animals, is directly involved in sleep in the nematode C. elegans.

Uncovering Residual Effects Of Chronic Sleep Loss On Human Performance

Sleep loss leads to profound performance decrements. Yet many individuals believe they adapt to chronic sleep loss or that recovery requires only a single extended sleep episode. To evaluate this, we designed a protocol whereby the durations of sleep and wake episodes were...

Sleep Apnea May Increase Insulin Resistance

Sleep apnea may cause metabolic changes that increase insulin resistance, according to researchers from the University of Pittsburgh Medical Center. The intermittent hypoxia associated with sleep apnea causes a...

The Longer You’re Awake, The Slower You Get

Anyone that has ever had trouble sleeping can attest to the difficulties at work the following day. Experts recommend eight hours of sleep per night for ideal health and productivity, but what if five to six hours of sleep is your norm? Is your work still negatively affected? A team of researchers at Brigham and Women's Hospital (BWH) have discovered that regardless of how tired you perceive yourself to be, that lack of sleep can influence the way you perform certain tasks.

A Good Night’s Slumber Won’t Reverse Chronic Sleep Loss

Deficits in functioning persist for those who frequently get too little shut-eye, study finds. Chronic sleep deprivation and the impact "sleep debt" has on functioning and thinking cannot be reversed by one good night's sleep, new research suggests. While a night of good sleep can make you feel and operate better in...

Sleep Deprivation Impairs cAMP Signalling In The Hippocampus.

Sleep deprivation impairs cAMP signalling in the hippocampus. Millions of people regularly obtain insufficient sleep. Given the effect of sleep deprivation on our lives, understanding the cellular and molecular pathways affected by sleep deprivation is clearly of social and clinical importance. One of the major effects of sleep deprivation on the brain is to produce memory deficits in learning models that are dependent on the hippocampus. Here we have identified a molecular mechanism by which brief sleep deprivation alters hippocampal...

The Key To Being Attractive (And Looking Healthy)? A Good Night’s...

If you want to look attractive and healthy, the best thing you can do is get a good night's sleep, finds research in the Christmas issue published on the British Medical Journal website.

For the first time, say the authors, there is scientific backing for the concept of beauty sleep.

Brain’s Energy Restored During Sleep, Suggests Animal Study

In the initial stages of sleep, energy levels increase dramatically in brain regions found to be active during waking hours, according to new research in the June 30 issue of the Journal of Neuroscience. These results suggest that a surge of cellular energy may replenish brain processes needed to function normally while awake.

More Adults Report Excessive Sleepiness In The US Than In Europe

Excessive sleepiness is more common in the U.S. than in Europe, which raises concerns for public health and safety, according to a research abstract presented June 8, 2010, in San Antonio, Texas, at SLEEP 2010, the 24th annual meeting of the Associated Professional Sleep Societies LLC.

Middle-Aged Men: Could Dwindling Testosterone Levels Decrease Sleep?

At 30 years old, male testosterone levels drop by one to two percent annually. By age 40, men's quality of sleep begins to diminish. Could there be a link between decreased testosterone and reduced sleep?

Secrets Of The ‘Sleep Hormone’: Discovery Leads To Novel Melatonin Drug...

A team from the Research Institute of the McGill University Health Centre (RI-MUHC) and McGill University has made a major breakthrough by unraveling the inner workings of melatonin, also known as the "sleep hormone." The research, conducted in collaboration with scientists in Italy,...

Short Sleepers At Higher Risk Of Type 2 Diabetes And Heart...

People who sleep less than six hours a night may be three times more likely to develop a condition which leads to diabetes and heart disease, according to researchers at the University of Warwick.
