Philadelphia, PA, November 8, 2012 – According to the Centers for Disease Control and Prevention, about 28% of adolescents are overweight. This means that about 1 in every 5 parents is thinking about how to discuss this with their child.

What was your high school mascot? Where did you put your keys last night? Who was the first president of the United States?
Groups of neurons in your brain are currently sending electromagnetic rhythms through established pathways in order for you to recall the answers to each of these questions. Researchers in Drexel's School of Biomedical Engineering, Science and Health Systems are now getting a rare look inside the brain to discover the exact pattern of activity that produces a memory.
Decision-making is an inevitable part of the human experience, and one of the most mysterious. For centuries, scientists have studied how we go about the difficult task of choosing A or B, left or right, North or South — and how both instinct and intellect figure into the process. Now new research indicates that the old truism "look before you leap" may be less true than previously thought.
AUGUSTA, Ga. – A 30-minute brain injury education program taught in the hospital may increase children's use of bicycle helmets, Georgia Health Sciences University researchers report.
The researchers provided bicycle helmet safety and brain injury prevention information to 120 patients age 5 to 18 at Georgia Health Sciences Children's Medical Center and found that helmet usage increased by 72.5 percent within the first month following the program – from only 11 children reporting wearing a bicycle helmet on every ride to 98 always wearing helmets.
Patients with obsessive-compulsive disorder are characterised by persistent thoughts and repetitive behaviours. A new study reveals that sufferers worry considerably more than the general population in the face of morality problems.
Along with the help of experts from the Barcelona's Hospital del Mar and the University of Melbourne (Australia), researchers at the Hospital de Bellvitge in Barcelona have proven that patients with obsessive-compulsive disorder, known as OCD, are more morally sensitive.
A new software product developed by researchers at the University of Cambridge could greatly improve sound perception for users of hearing aids.
Dream images could provide insights into people's mental health problems and may help with their treatment, according to a psychology researcher from the University of Adelaide.
Dr Lance Storm, a Visiting Research Fellow with the University of Adelaide's School of Psychology, has been studying dream symbols (or "archetypes") and their meanings, as described by the famous psychologist and psychiatrist, Carl Jung.
Armoured in elaborate scales, the skins of crocodiles and alligators are much prized by the fashion industry. But sadly, not all skins are from farmed animals. Some are from endangered species and according to Ken Catania from Vanderbilt University, USA, sometimes the only way to distinguish legitimate hides from poached skins is to look at the distribution of thousands of microscopic pigmented bumps that pepper crocodiles' bodies.
Crocodiles and alligators are notorious for their thick skin and well-armored bodies. So it comes as something of a surprise to learn that their sense of touch is one of the most acute in the animal kingdom.
The crocodilian sense of touch is concentrated in a series of small, pigmented domes that dot their skin all over their body. In alligators, the spots are concentrated around their face and jaws.
Caffeine perks up most coffee-lovers, but a new study shows a small dose of caffeine also increases their speed and accuracy for recognizing words with positive connotation. The research published November 7 in the open access journal PLOS ONE by Lars Kuchinke and colleagues from Ruhr University, Germany, shows that caffeine enhances the neural processing of positive words, but not those with neutral or negative associations.
"Visual diet," or the images that women see, may be just as critical to their weight preferences as associating certain body types with success, according to research published Nov. 7 in the open access journal PLOS ONE by Lynda Boothroyd at Durham University with colleagues from Newcastle University, United Kingdom.
British women's obsession for thin bodies could potentially be changed if advertising showed more plus size models, suggests a preliminary study published today (7 Nov).
The Durham University researchers, who studied over 100 women, provide evidence to back calls for models in adverts to be more representative of the actual population. This move could ultimately help girls and women to develop a healthier attitude to eating, the researchers say.
Professor Alexander Bentley and colleagues found that words commonly used by scientists when discussing climate science – such as 'biodiversity', 'global', and 'isotopes' – follow fashion cycles in public usage as the usage of such words by scientists diffuses into use by non-scientists. According to the authors, this effect may contribute to the impact of climate research on societal perceptions.
Athens, Ga. – To boost self-control, gargle sugar water. According to a study co-authored by University of Georgia professor of psychology Leonard Martin published Oct. 22 in Psychological Science, a mouth rinse with glucose improves self-control.
