Challenging the old notion that the function of sleep is to rest the brain, researchers show that not getting enough sleep can harm fat cells, reducing by 30 percent their ability to respond to insulin, a hormone that regulates energy. This is the first description of a molecular mechanism directly connecting sleep loss to the disruption of energy regulation.

Smoking, head injury, pesticide exposure, farming and less education may be risk factors for a rare sleep disorder that causes people to kick or punch during sleep, according to a study published in the June 27, 2012, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Women with polycystic ovary syndrome (PCOS) who also have obstructive sleep apnea have at least three times the risk of having prediabetes compared with women who do not have PCOS, according to a new study. The results will be presented Tuesday at The Endocrine Society’s 94th Annual Meeting in Houston.
The Center for Minimally Invasive and Robotic Surgery at The Mount Sinai Medical Center—a pioneer in robotic surgery—now offers the procedure to patients with sleep apnea, whose obstructive breathing prevents them from sleeping normally.
No drug treatments exist to treat sleep apnea, a disorder that affects more than 18 million Americans. Researchers at the University of Illinois at Chicago have received a $5 million three-year federal grant to find out if a cannabinoid drug can reduce sleep apnea and protect against diseases linked to the illness.
Obstructive sleep apnea (OSA) is independently associated with diabetic peripheral neuropathy (DPN) in patients with type 2 diabetes mellitus (T2DM), according to a new study from researchers in the UK.
People with insomnia may now have one more thing to keep them up at night: an increased likelihood of developing hypertension, according to a study from Henry Ford Hospital in Detroit. The study will be presented Tuesday, June 12 at the Sleep 2012 Conference in Boston.
Researchers at New York University and Albert Einstein College of Medicine of Yeshiva University have discovered new ways neurons work together to ease the transition between sleep and wakefulness. Their findings provide additional insights into sleep-wake patterns and offer methods to explore what may disrupt them.
Weight loss improved both metabolic parameters and sleep-disordered breathing (SDB) in obese children in a new study from researchers in Belgium, confirming links between metabolic dysregulation, SDB and obesity.

Treatment of obstructive sleep apnea (OSA) in children normalizes disturbances in the neuronal network responsible for attention and executive function, according to a new study.
Researchers have discovered a mechanism involving the neurotransmitter dopamine that switches fruit fly behavior from being active during the day (diurnal) to nocturnal. This change parallels a human disorder in which increased agitation occurs in the evening hours near sunset and may also be due to higher than normal dopamine levels in the brain.
Chronic pain sufferers who learn to dwell less on their ailments may sleep better and experience less day-to-day pain, according to results of research conducted on 214 people with chronic face and jaw pain.
Researchers have developed a unique model that mimics obstructive sleep apnea (OSA) in humans. The approach has found that after just 30 days of OSA exposure, cerebral vessel function is altered, which could lead to stroke.
