Swiss researchers say the so called love hormone -- oxytocin -- eases conflict stress. The study, published in Biological Psychiatry, evaluated how real-time behavior in couples was affected by exposure to either oxytocin or a placebo. The researchers recruited adult couples who received oxytocin or placebo intranasally -- within the nose. The couples then engaged in conflict discussion while in the laboratory. The researchers find oxytocin increased positive communications more than a...

Ten years ago, Stanford University School of Medicine scientist Emmanuel Mignot, MD, PhD, and his colleagues made headlines when they identified the culprit behind the sleep disorder narcolepsy. Now Mignot and his collaborators have shown for the first time that a specific immune cell is involved in the disorder "” confirming experts' long-held suspicion that narcolepsy is an autoimmune disease. The work, which will be published online May 3 in Nature Genetics, could lead to better...

Relationships are difficult and most of us probably think at some point that communicating positively with our partner when discussing stressful issues, like home finances, is an impossible task. What if there was a safe way to take the "edge" off these discussions? The biology of human social relationships is just beginning to emerge as groundbreaking research on social cognition conducted in animals is now informing research in humans. In its May 1st issue, Biological Psychiatry, published...

LOS ANGELES, April 28 /PRNewswire/ -- Is your mattress making you fat? SleepBook.com, sponsored by Sit 'n Sleep, recently interviewed two sleep experts to find out; their answers were surprisingly candid. Medical studies performed in the past few years are revealing that sleep loss can contribute to weight gain. "It interferes with our circadian rhythms and with the way we regulate our hormones," William Kohler, medical director of the Florida Sleep Institute, says. There are two...

Insomnia has long been associated with poor health, including weight gain and even obesity. Now researchers at UCLA have found out why.In a study to be published in the May issue of the journal Psychoneuroendocrinology and currently available online by subscription, Sarosh Motivala, an assistant professor of psychiatry at the Semel Institute for Neuroscience and Human Behavior at UCLA, and colleagues looked at two hormones that are primarily responsible for regulating the body's energy...

A U.S. researcher said on Sunday that soldiers who perform best under extreme stress have higher levels of chemicals that dampen the fear response, Reuters reported. Many say the finding could lead to new drugs or training strategies to help others cope better with intense combat situations. Deane Aikins of Yale University in New Haven, Connecticut said that certain individuals just don't get as stressed as others. "Their stress hormones are actually lower," she told reporters at the...

Researchers have found that kissing unleashes chemicals that ease stress hormones in both sexes and encourages bonding in men, though not so much in women, according to the Associated Press. Wendy Hill, a professor of neuroscience at Lafayette College, told a meeting of the American Association for the Advancement of Science on Friday that chemicals in the saliva might be a way to assess a mate. A study involving pairs of heterosexual college students who kissed for 15 minutes while listening...

According to Bianca Acevedo, a New York neuroscientist, love is in the head and not the heart. Acevedo is part a new field in science that seeks to biologically explain love, and so far they have found that love is mostly understood through hormones, genetics, and brain images, according to a report from the Associated Press. "It has a biological basis. We know some of the key players," said Larry Young of the Yerkes National Primate Research Center, where he searches for clues as to what...

U.S. medical scientists say they've discovered increased levels of a natural brain chemical can block weight gain. The researchers at the University of Texas Southwestern Medical Center found mice with increased levels of the chemical orexin don't gain weight when fed a high-fat diet. The chemical works by increasing the body's sensitivity to the so-called weight-loss hormone leptin, the researchers said. Professor Masashi Yanagisawa, senior author of the study, said finding a way to boost...

Falling asleep involuntarily during the day poses a very real and dangerous problem, Canadian researchers said. Researchers at the Montreal Neurological Institute at McGill University demonstrates sleep-wake states are regulated by two types of nerve cells, melanin-concentrating hormone neurons and orexin neurons, which occupy the same region of the brain, but perform opposite functions. The study is the first to discover that melanin-concentrating hormone neurons are activated during sleep...

Labor Induction is a process of giving an artificial start to birth with medical intervention or other methods. When an induction is not performed for emergency or other medical reasons, the method is considered an elective process. The decision to induce labor has increased in recent years due to its convenience or because it easily accommodates busy schedules. The American College of Obstetricians and Gynecologists, however, say that labor should only be induced when it is more risky...
