A new study shows that both length of time and percentage of overall sleep spent in different sleep stages are associated with decreased metabolic rate, increased hunger, and increased intake of calories (specifically from fat and carbohydrates). The findings suggest an explanation for the association between sleep problems and obesity. Researchers from St. Luke's-Roosevelt Hospital and Columbia University investigated the effects of sleep architecture on hunger to determine whether...

Is sleep learning possible? A new Weizmann Institute study appearing today in Nature Neuroscience has found that if certain odors are presented after tones during sleep, people will start sniffing when they hear the tones alone — even when no odor is present — both during sleep and, later, when awake. In other words, people can learn new information while they sleep, and this can unconsciously modify their waking behavior. Sleep-learning experiments are notoriously difficult to...

Lee Rannals for RedOrbit.com Ever dreamt that you were attempting to run from someone, but couldn't get away and were actually running in place?  Well, a new sleeping mask may see to it that you are able to escape, scot-free, from now on. Scientists have developed a sleeping mask, known as Remee, that allows people to control their own dream. Remee, which is billed as a special REM enhancing device, helps steer people into dreaming by making the brain aware that it is dreaming....

Researchers at Boston University School of Medicine (BUSM) have, for the first time, identified an intracellular signaling enzyme that regulates the wake-sleep cycle, which could help lead to the development of more effective sleep aid medications. Subimal Datta, PhD, director and principle investigator at the Laboratory of Sleep and Cognitive Neuroscience at BUSM, led the study, which points to a specific enzyme inside neurons in the brain that trigger an important shift in consciousness...

Poor Sleep Quality Can Affect Blood Pressure

  A new study has found that older men who suffer from a lack of deep sleep are nearly twice as likely to have high blood pressure (HBP), reports BBC News. The new research, published in Hypertension: Journal of the American Heart Association, suggests that reduced slow wave sleep (SWS) is a powerful predictor for developing the condition that causes deadly heart attack, stroke and other health problems. SWS, a deep stage of sleep, is characterized by non-rapid eye movement...

Napping on a slowly swinging bed helps us to both fall asleep faster and encourages a deeper sleep than stationary beds, according to findings published in the June 21 issue of Current Biology, a Cell Press publication. "It is a common belief that rocking induces sleep: we irresistibly fall asleep in a rocking chair and, since immemorial times, we cradle our babies to sleep," says one of the study's co-authors, Sophie Schwartz of the University of Geneva. "The goal of our study was twofold,"...

New research finds that consistent, "signature" brainwave patterns first noticed in short-term studies of adults are so robust that they're also detectable over a matter of years in the notoriously turbulent brains of teens. From there, the question is what such a "neural fingerprint" might mean. Teens are rarely described as stable, so when something about their rapidly changing brains remains placidly unaltered, neuroscientists take notice. Such is the case in a new study of...

(Ivanhoe Newswire) -- Why do we sleep?  I mean, we spend so much of our time sleeping that it must be doing something important.  It seems pretty simple right?  Not exactly.  There are myriad theories about rapid eye movement (REM) sleep, however, scientists have spent many sleepless nights determining why we spend so many hours in light, dreamless slumber.  Well, according to a new-fangled study, it is suggested that we are busy recharging our brain's learning...

By Yasmin Anwar, UC Berkeley A UC Berkeley study suggests we're busy recharging our brain's learning capacity during a dreamless light slumber that takes up half our sleeping hours Scientists have long puzzled over the many hours we spend in light, dreamless slumber. But a new study from the University of California, Berkeley, suggests we're busy recharging our brain's learning capacity during this traditionally undervalued phase of sleep, which can take up half the night. UC Berkeley...

A team of sleep scientists led by Dr. Fabio Ferrarelli of the University of Wisconsin-Madison found that during non-rapid eye movement sleep (non-REM, or dreamless sleep), the brain waves produced by people with schizophrenia lack the normal pattern of slow and fast spindles. Madison, Wis. (Vocus) November 23, 2010 When people with schizophrenia sleep, their brain waves show a distinctive pattern that may someday lead to one of the first biological markers for this devastating mental...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
