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?
Is Your Sister or Daughter Getting Enough of This... Maybe you haven’t given much thought to this vitamin but a new study in Psychiatry Research shows why we need to get real.  It reported that nearly 50% of young women … ...
Swedish diagnostic method for Alzheimer's becomes international standard Researchers have developed a reference method for standardized measurements that diagnose Alzheimer's disease decades before symptoms appear. The method has now formally been classified as the international reference method, which means that it will be used as the standard in Alzheimer's diagnostics worldwide.
Innate immune system modulates severity of multiple sclerosis Multiple sclerosis, a debilitating neurological disease, is triggered by self-reactive T cells that successfully infiltrate the brain and spinal cord where they launch an aggressive autoimmune attack against myelin, the fatty substance that surrounds and insulates nerve fibers. In their latest study, researchers report that these disease-causing autoimmune T cells are lured into the nervous system by monocytes and macrophages, a subset of immune cells better known as the immune system's cleanup crew.
The Mysteries of Habit Neuroscience research brings together seemingly unrelated conditions...anorexia, OCD and substance use disorders...which may share common -- and difficult-to-modify -- brain circuits related to habit learning.
Narcissism and Parental Alienation Syndrome It is beneficial for therapists, those in the law profession, and individuals involved with the children of narcissistic clients or partners to be aware of a concept known as parental alienation syndrome, how it is created, and what to do about it.  In a normal attachment … ...
Why Worry Is Nothing But a Gloomy Daydream Do you consider yourself a worrier? Although everyone worries from time to time, some people are plagued by worry on a daily basis. They tend to fall into a pattern of catastrophic thinking — always preparing for the very worst case scenario. Not only is … ...
