Researchers from the University of Colorado Health Sciences Center, along with colleagues from Stanford University, report the results of a large-scale, genome-wide study to investigate gene copy number differences among ten primate species, including humans. The study provides an overview of genes and gene families that have undergone major copy number expansions and contractions in different primate lineages spanning approximately 60 million years of evolutionary time.

Giving inner-city children a safe place to play could dramatically increase their level of physical activity and even cut down on the time they spend watching television and playing video games. Researchers opened a schoolyard and provided attendants to ensure children's safety. Over the next two years researchers observed the number and physical activity levels of children in the schoolyard and surrounding neighborhood and a comparison neighborhood.

Even relatively low quantities of air pollution increase the risk of premature death, according to an article published in Thorax. Black smoke and sulphur dioxide were found to have the closest associations with raising the risk of early death. Air quality in different British electoral wards were checked over long and varying periods, say the researchers. They also examined national data on causes of death.

An estimated 135,000 (65 percent) of sports- and recreation-related traumatic brain injuries (TBI) treated in U.S. emergency departments occur each year in young people ages 5 to 18, according to a study published in the Centers for Disease Control and Prevention′s Morbidity and Mortality Weekly Report (MMWR). Approximately 8 percent, or more than 10,000, of these young people were hospitalized, the study said.

Scientists from three leading UK research institutes have released new findings that could have major implications for food production and global warming in the 21st century. Their research is published online in Nature.Experts from the Met Office, the University of Exeter and the Centre for Ecology & Hydrology, have found that projections of increasing ozone near the Earth's surface could lead to significant reductions in regional plant production and crop yields.
