Researchers at the Norris Cotton Cancer Center have found that current constraints on advertising for alcohol products in movies that adolescents watch are not effective. The study, "Trends in Tobacco and Alcohol Brand Placements in Popular US movies, 1996 through 2009,"was published online in the May 27, 2013 JAMA Pediatrics. http://medicalxpress.com/news/2013-05-effective-alcohol-brand-placements-movies.html Pediatrics Mon, 27 May 2013 16:00:05 EST news288872859 New research presented today shows that formation of new neurons in the hippocampus - a brain region known for its importance in learning and remembering - could cause forgetting of old memories by causing a reorganization of existing brain circuits. Drs. Paul Frankland and Sheena Josselyn, both from the Hospital for Sick Children in Toronto, argue this reorganization could have the positive effect of clearing old memories, reducing interference and thereby increasing capacity for new learning. These results were presented at the 2013 Canadian Neuroscience Meeting, the annual meeting of the Canadian Association for Neuroscience - Association Canadienne des Neurosciences (CAN-ACN). http://medicalxpress.com/news/2013-05-neuron-formation-capacity-expense-memories.html Neuroscience Fri, 24 May 2013 09:30:03 EST news288605755 (HealthDay)—Reviews that are funded by industry tend to find the evidence weak for a causal link between sugar-sweetened beverages (SSBs) and the increasing prevalence of obesity, while other reviews consider the evidence well founded, according to research presented at the annual meeting of the European Congress on Obesity, held from May 12 to 15 in Liverpool, U.K. http://medicalxpress.com/news/2013-05-eco-industry-funded-query-sweet-obesity.html Overweight and Obesity Tue, 14 May 2013 17:50:01 EST news287771296 Researchers at the University of Alabama at Birmingham (UAB) report that children with cerebral palsy who underwent Constraint Induced Movement therapy (CI therapy) saw a significant increase in grey matter volume in areas of the brain associated with movement. The findings, published online April 22, 2013 in Pediatrics, are the first to show that structural remodeling of the brain occurs during rehabilitation in a pediatric population. http://medicalxpress.com/news/2013-04-ci-therapy-grey-brains-children.html Neuroscience Tue, 23 Apr 2013 10:00:01 EST news285929203 Children and teens with autism spectrum disorder (ASD) use screen-based media, such as television and video games, more often than their typically developing peers and are more likely to develop problematic video game habits, a University of Missouri researcher found. http://medicalxpress.com/news/2013-04-children-teens-autism-preoccupied-video.html Autism spectrum disorders Wed, 17 Apr 2013 12:51:26 EST news285421866 How does being in a position of power at work, with friends, or in a romantic relationship influence well-being? While we might like to believe the stereotype that power leads to unhappiness or loneliness, new research indicates that this stereotype is largely untrue: Being in a position of power may actually make people happier. http://medicalxpress.com/news/2013-01-power-good-life-closer-true.html Psychology & Psychiatry Mon, 28 Jan 2013 16:20:12 EST news278612403 The scientific community have long debated the causal relationship between cannabis use and the risk factor for psychotic illnesses such as schizophrenia. Both sides of this controversial subject are put forward in two articles published today in F1000 Medicine Reports. To give rise to the debate, the authors of each article were given the opportunity to read the opposing side's article drafts and consider their arguments when structuring their own article. http://medicalxpress.com/news/2013-01-cannabis-psychosis-debate.html Psychology & Psychiatry Fri, 11 Jan 2013 09:53:15 EST news277120387 New research suggests that racial stereotypes and creativity have more in common than we might think. http://medicalxpress.com/news/2013-01-racial-essentialism-creative-people-closed-minded.html Psychology & Psychiatry Mon, 07 Jan 2013 12:49:28 EST news276785361 Accumulating evidence suggests that certain brain areas involved in processing physical pain may also underlie feelings of social pain.

The study by Jennifer Cohen and Michelle Ruha from Banner Good Samaritan Medical Center in the US, and their colleagues, provides evidence against the use of these treatments in children with autism.

The study, published in Nature Genetics in July, found patients who had a specific kind of kidney disease — called karyomegalic interstitial nephritis — were likely to also have a mutation on a particular gene, FAN1, which codes for a protein that helps fix DNA damage. http://medicalxpress.com/news/2012-08-collaboration-kidney-disease-tied-dna.html Genetics Thu, 09 Aug 2012 06:51:35 EST news263713872 Research has shown that older adults display more positive emotions and are quicker to regulate out of negative emotional states than younger adults.
