Decreased physical activity may have little to do with the recent spike in obesity rates among U.S. adolescents, according to researchers at the Johns Hopkins Bloomberg School of Public Health. Prompted by growing concern that the increase was due to decreased physical activity associated with increased TV viewing time and other sedentary behaviors, researchers examined the patterns and time trends in physical activity and sedentary behaviors among U.S. adolescents based on nationally representative data collected since 1991.

The rapid growth of China's forests over the past 20 years makes them the fastest growing forest resources in the world, according to an assessment published in the November issue of BioScience.
The study, by Haigen Xu of the Nanjing Institute of Environmental Sciences and nine colleagues, examined an array of indicators of biodiversity in China as part of an effort to assess China's progress toward the goals of the Convention of Biological Diversity. Parties to the convention agreed in 2002 to reduce biodiversity loss significantly by 2010.
TORONTO, ON. – Adults who had experienced physical abuse as children have 56 per cent higher odds of osteoarthritis compared to those who have not been abused, according to a new study by University of Toronto researchers.
University of Toronto researchers investigated the relationship between self-reported childhood physical abuse and a diagnosis of osteoarthritis (OA). After analyzing representative data from the 2005 Canadian Community Health Survey, the researchers determined a significant association between childhood physical abuse and osteoarthritis in adulthood.
The swine flu (H1N1) pandemic has received extensive media coverage this year. The World Health Organization, in addition to providing frequent updates about cases of infection and death tolls, recommends hyper vigilance in daily hygiene such as frequent hand washing or sneezing into the crook of our arms. News reports at all levels, from local school closures to airport screenings and global disease surveillance, continue to remind us of the high risk.
HONOLULU – October 30, 2009 – Shire plc (LSE: SHP, NASDAQ: SHPGY), the global specialty biopharmaceutical company, today announced findings at a major medical meeting from a Phase IIIb study of the tolerability and effectiveness of Daytrana® (methylphenidate transdermal system) in adolescents aged 13 to 17 years diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD). In addition, data regarding the pharmacokinetic profile of Daytrana in children and adolescents was also presented.
A team of physicists has directly observed a reverse shock wave of light in a specially tailored structure known as a left-handed metamaterial. Although it was first predicted over forty years ago, this is the first unambiguous experimental demonstration of the effect. The research is reported in Physical Review Letters and highlighted with a Viewpoint in the November 2 issue of Physics (phyics.aps.org).
Nov. 2, 2009 -- Elder Tommy George has not spoken his aboriginal language of Kuku Thaypan for three years, since his brother died. "It might die in the throat, but it stays alive in the heart," he said to the Queensland Courier-Mail in June, 2009.
What happens when you no longer have anyone to talk to in your own language?
Research published in the November 2009 issue of the Journal of Thoracic Oncology has found that intervals between lung cancer suspicion, diagnosis and treatment may be attributed to health care system discrepancies.
WESTCHESTER, Ill. - A study in the Nov.1 issue of the journal Sleep shows that retirement is followed by a sharp decrease in the prevalence of sleep disturbances. Findings suggest that this general improvement in sleep is likely to result from the removal of work-related demands and stress rather than from actual health benefits of retirement.
Chestnut Hill, Mass. (October 30, 2009) -- The rise of social media and real-time advocacy have re-written the community outreach rules companies followed for decades. But many American firms are dragging their feet as they approach "Community Relations 2.0," Boston College researchers report in the November issue of Harvard Business Review.
A new study reveals the important role inherited wealth plays in sustaining economic inequality in small scale societies. A team of 26 anthropologists, statisticians, and economists based at the Santa Fe Institute in New Mexico amassed an unprecedented data set allowing 43 estimates of a family's wealth inheritance and found that financial inequality among populations largely depends on the "technologies" that produce a people's livelihood.
There has been a breakthrough in the fight against the deadly Hendra virus following the development of a treatment which shows great potential to save the lives of people who become infected with the virus.
A scientific team from CSIRO and the US has demonstrated that administering human monoclonal antibodies after exposure to Nipah virus, which is closely related to Hendra virus, protected animals from challenge in a disease model.
A diet high in fructose increases the risk of developing high blood pressure (hypertension), according to a paper being presented at the American Society of Nephrology's 42nd Annual Meeting and Scientific Exposition in San Diego, California. The findings suggest that cutting back on processed foods and beverages that contain high fructose corn syrup (HFCS) may help prevent hypertension.
Get-togethers with a kidney disease patient's family and friends can improve their willingness to consider donation, according to a paper being presented at the American Society of Nephrology's 42nd Annual Meeting and Scientific Exposition in San Diego, CA. The findings indicate that group-education of patients' relatives and friends is an effective way to help alleviate the organ shortage and increase living donations.
Compared with veteran doctors, recent medical school graduates are more likely to refer chronic kidney disease (CKD) patients for kidney transplantation before their patients require dialysis, according to a paper being presented at the American Society of Nephrology's 42nd Annual Meeting and Scientific Exposition in San Diego, CA. These findings suggest that more recent medical training is associated with early referral. This is potentially due to a lack of knowledge about preemptive kidney transplantation among more veteran physicians.
