CORAL GABLES, FL (July 11, 2012)—Emotional problems in childhood are common. Approximately 8 to 22 percent of children suffer from anxiety, often combined with other conditions such as depression. However, most existing therapies are not designed to treat co-existing psychological problems and are therefore not very successful in helping children with complex emotional issues.

Philadelphia, PA, July 30, 2012 – Is attention-deficit/hyperactivity disorder (ADHD) due to a delay in brain development or the result of complete deviation from typical development? In the current issue of Biological Psychiatry, Dr. Philip Shaw and colleagues present evidence for delay based on a study by the National Institutes of Health.
HAMILTON, ON (July 30, 2012) – Child abuse experts say psychological abuse can be as damaging to a young child's physical, mental and emotional health as a slap, punch or kick.
While difficult to pinpoint, it may be the most challenging and prevalent form of child abuse and neglect, experts say in an American Academy of Pediatrics (AAP) position statement on psychological maltreatment in the August issue of the journal Pediatrics.
Kansas City, Missouri - The vomeronasal organ (VNO) is one of evolution's most direct enforcers. From its niche within the nose in most land-based vertebrates, it detects pheromones and triggers corresponding basic-instinct behaviors, from compulsive mating to male-on-male death matches. A new study from the Stowers Institute for Medical Research, published online in Nature Neuroscience on July 29, 2012, extends the scientific understanding of how pheromones activate the VNO, and has implications for sensory transduction experiments in other fields.
TALLAHASSEE, Fla. Knock, knock! Who's there? Cows go. Cows go who? No, cows go moo!
OK, OK. So it's not a side-slapper — especially if the teller has zero sense of comic timing. But most likely the person sharing the joke over the water cooler thinks he or she is pretty funny.
No matter how badly the joke is told, it will sometimes elicit a few polite laughs.
Why?
Researchers at the University of Michigan Kellogg Eye Center have identified a compound that could interrupt the chain of events that cause damage to the retina in diabetic retinopathy. The finding is significant because it could lead to a novel therapy that targets two mechanisms at the root of the disease: inflammation and the weakening of the blood barrier that protects the retina.
To date, treatments for diabetic retinopathy, the leading cause of blindness among working-age Americans, have been aimed largely at one of those mechanisms.
In a University of Missouri study, girls and boys started grade school with different approaches to solving arithmetic problems, with girls favoring a slow and accurate approach and boys a faster but more error prone approach. Girls' approach gave them an early advantage, but by the end of sixth grade boys had surpassed the girls.
FINDINGS:
Researchers at UCLA have identified a novel molecule in the brain that, after stroke, blocks the formation of new connections between neurons. As a result, it limits the brain's recovery. In a mouse model, the researchers showed that blocking this molecule—called ephrin-A5--induces axonal sprouting, that is, the growth of new connections between the brain's neurons, or cells, and as a result promotes functional recovery.
IMPACT:
Adults with HIV in rural sub-Saharan Africa who receive antiretroviral drugs early in their infection may reap benefits in their ability to work and their children's ability to stay in school, according to a first-of-its-kind clinical study in Uganda that compared socioeconomic outcomes with CD4+ counts—a standard measure of health status for people with HIV.
If you have ever looked over the edge of a cliff and felt dizzy, you understand the challenges faced by people who suffer from symptoms of vestibular dysfunction such as vertigo and dizziness. There are over 70 million of them in North America. For people with vestibular loss, performing basic daily living activities that we take for granted (e.g. dressing, eating, getting in and out of bed, getting around inside as well as outside the home) becomes difficult since even small head movements are accompanied by dizziness and the risk of falling.
July 27, 2012 – (BRONX, NY) – In a study published today online in Science, researchers at Albert Einstein College of Medicine of Yeshiva University have determined the complete wiring diagram for the part of the nervous system controlling mating in the male roundworm Caenorhabditis elegans, an animal model intensively studied by scientists worldwide.
Can the simple act of recognizing a face as you walk down the street change the way we think? Or can taking the time to notice something new on our way to work change what we remember about that walk? In a new study published in the journal Science, New York University researchers show that remembering something old or noticing something new can bias how you process subsequent information.
How do sexual cues affect consumer behavior? New research from USC Marshall School of Business Assistant Professor of Marketing Kyu Kim and Gal Zauberman, associate professor of marketing at The Wharton School at the University of Pennsylvania, reveals the reasons why sexual cues cause us to be impatient and can affect monetary decisions.
A brief therapeutic intervention called motivational interviewing, administered over the telephone, was significantly more effective than a simple "check-in" call in getting Iraq and Afghanistan war veterans with mental health diagnoses to begin treatment for their conditions, in a study led by a physician at the San Francisco VA Medical Center and the University of California, San Francisco.
