In a promising development for diabetes treatment, researchers have developed a network of nanoscale particles that can be injected into the body and release insulin when blood-sugar levels rise, maintaining normal blood sugar levels for more than a week in animal-based laboratory tests. The work was done by researchers at North Carolina State University, the University of North Carolina at Chapel Hill, the Massachusetts Institute of Technology and Children's Hospital Boston...

As parents, physicians and policymakers look for ways to curb childhood obesity, they may need to look no further than a child's own backyard. A new study presented at the Pediatric Academic Societies (PAS) annual meeting shows that preschool children are less likely to be obese if they live in a neighborhood that is safe and within walking distance of parks and retail services. "A child's neighborhood is a potentially modifiable risk factor for obesity that we can target in order to stop the increasing prevalence of obesity in young children," said lead author Julia B...

The Research Group headed by molecular biologist Andrea Pichler from the Max Planck Institute of Immunobiology and Epigenetics in Freiburg has made an important discovery in meiosis research. Pichler and her group have identified a new mechanism that plays an important role in meiosis. Meiosis, also called reductional division, is a key process in sexual reproduction. It shuffles parental genetic material and thus guarantees genetic variety...

It's no secret that stress increases your susceptibility to health problems, and it also impacts your ability to solve problems and be creative. But methods to prevent associated risks and effects have been less clear - until now.

Teenagers who are highly exposed to violent video games - three or more hours per day - show blunted physical and psychological responses to playing a violent game, reports a study in the May issue of Psychosomatic Medicine: Journal of Biobehavioral Medicine, the official journal of the American Psychosomatic Society. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health...

Mathematicians from Queen Mary, University of London will bring researchers one-step closer to understanding how the structure of the brain relates to its function in two recently published studies. Publishing in Physical Review Letters the researchers from the Complex Networks group at Queen Mary's School of Mathematical Sciences describe how different areas in the brain can have an association despite a lack of direct interaction...

New research indicates that Mexican-Americans born in the United States who are aged 55 and over are significantly more likely than Mexican-American immigrants to report that they have substantial limitations in one or more basic physical activity such as walking, climbing stairs, reaching, lifting, or carrying. (30% versus 25%). The research, published in the International Journal of Environmental Research and Public Health, was a joint study by the University of Toronto and the University of California, Berkeley...

Opposing thumbs, expressive faces, complex social systems: it's hard to miss the similarities between apes and humans. Now a new study with a troop of zoo baboons and lots of peanuts shows that a less obvious trait - the ability to understand numbers - also is shared by man and his primate cousins. "The human capacity for complex symbolic math is clearly unique to our species," says co-author Jessica Cantlon, assistant professor of brain and cognitive sciences at the University of Rochester...

Using regional anesthesia instead of general anesthesia in patients with sleep apnea undergoing total joint replacement decreases major complications by 17%, according to a study published online, ahead of print, in the journal Regional Anesthesia and Pain Medicine. The Hospital for Special Surgery study is the first to provide evidence that an intervention during surgery can improve outcomes in patients with sleep apnea who often fare worse than patients without this condition. Currently, up to 25% of patients presenting for surgery in the United States have sleep apnea...
