Neurobiological study links sex addiction to overactive stress systems New research from Karolinska Institutet in Sweden shows that hypersexual disorder – known popularly as sex addiction – can be linked to hyperactive stress systems. In a stress regulation test using the cortisone drug dexamethasone, men with hypersexual disorder showed higher levels of stress hormones than controls, a finding that the researchers hope will contribute [...]
Lack of exercise linked to alcohol misuse A large-scale survey of African-American men and women found that those who rarely or never exercised had about twice the odds of abusing alcohol than those who exercised frequently, a finding that could have implications across all groups. The survey of 5,002 African-American men and women found that those who did not engage in physical [...]
Research shows devastating effect war and violence has on children’s mental health Violence and conflict in areas affected by war, such as Gaza, can have a devastating effect on the mental health of the children exposed to it, according to research at the University of Leicester. After extensive research into trauma caused by war, Dr Panos Vostanis from the University of Leicester’s Department of Neuroscience, Psychology and [...]

Anti-smoking messages can make it harder for people to quit, research suggests Public health policies targeted at smokers may actually have the opposite effect for some people trying to quit, according to new evidence released today (Nov. 2). Research indicates that stigmatizing smoking can, in some cases, make it harder for people to quit because they become angry and defensive and the negative messages lead to a [...]
Sleepwalkers feel no pain, remain asleep despite suffering injuries A new study of sleepwalkers found an intriguing paradox: Although sleepwalkers have an increased risk for headaches and migraines while awake, during sleepwalking episodes they are unlikely to feel pain even while suffering an injury. Results show that sleepwalkers were nearly 4 times more likely than controls to report a history of headaches (odds ratio [...]
Study reveals new link between Down syndrome and Alzheimer’s Individuals with Down syndrome who survive into adulthood face the additional challenge of early-onset dementia, in which toxic amyloid plaques build up in the brain. The condition is strikingly similar to Alzheimer’s disease, and as new work led by researchers at the Lewis Katz School of Medicine at Temple University (LKSOM) shows, dementia in Down [...]
Infants have social capacity to recognize new communicative signals in their environment Researchers have long known that adults can flexibly find new ways to communicate, for example, using smoke signals or Morse code to communicate at a distance, but a new Northwestern University study is the first to show that this same communicative flexibility is evident even in 6-month-olds. The researchers set out to discover whether infants [...]
Seeing More Clearly After Trauma and Denial Have you ever been surprised by watching a movie or television show a decade after you first watched it and saw it in a whole new light? You’re older, you’re in a different place and so the experience of watching that film or show again … ...
Do you buy local? Your consumer ethnocentrism may be showing Are you are one of the many consumers who prefer domestic to foreign products, even when the domestic products are lower in quality and cost more? Why is that? As a new study in the Journal of International Marketing explains, you are exhibiting what is known as consumer ethnocentrism–a thirty-year-old concept, says the study, whose conceptual [...]
New study suggests fair division of chores leads to better sex life Looking for more and better sex? If you’re a man, you might consider doing the dishes once in a while. A new study out of the University of Alberta reveals that couples enjoyed more frequent and satisfying sex for both partners when men made a fair contribution to housework. The same study also found there’s [...]
Children’s self-esteem already established by age 5, new study finds By age 5 children have a sense of self-esteem comparable in strength to that of adults, according to a new study by University of Washington researchers. Because self-esteem tends to remain relatively stable across one’s lifespan, the study suggests that this important personality trait is already in place before children begin kindergarten. “Our work provides [...]
Dartmouth ‘inner GPS’ study may aid diagnosis of brain diseases A new Dartmouth study sheds light on brain cells in our “inner GPS,” which may improve understanding of memory loss and wandering behavior in people with Alzheimer’s and other neurodegenerative diseases. The findings, which appear in the journal Current Biology, contribute to our understanding of the neural mechanisms underlying our ability to navigate our environment. [...]
Eye drops deliver gene therapy for brain disorders Eye drops have been used to deliver the gene for a growth factor called granulocyte colony stimulating factor (G-CSF) in a mouse model of brain ischemia. The treatment led to a significant reduction in brain atrophy, neurological deficits, and death in the mice. The research team also devised a system to monitor the success of the gene delivery using MRI. The combination of simple delivery and non-invasive monitoring has the potential to contribute to improved studies of experimental gene therapy in animal models of stroke, Alzheimer’s dementia, Parkinson’s disorder, and ALS. The system also offers the intriguing possibility that acute brain injury may someday be treated by emergency medical workers through the simple delivery of eye drops carrying a therapeutic gene.
'Inner GPS' study may aid diagnosis of brain diseases A new study sheds light on brain cells in our 'inner GPS,' which may improve understanding of memory loss and wandering behavior in people with Alzheimer's and other neurodegenerative diseases.

Chopin, Bach used human speech ‘cues’ to express emotion in music Music has long been described, anecdotally, as a universal language. This may not be entirely true, but we're one step closer to understanding why humans are so deeply affected by certain melodies and modes.
What Makes a House Feel Haunted? The portrayal of cinematic haunted houses has remained remarkably consistent across time, and the architects of our annual macabre Halloween rituals incorporate all of the same bells and whistles (okay – creaks and groans) that we’ve come to expect. What is it in our evolutionary past that makes some types of houses feel so creepy?
