The number of people living with HIV in the Middle East and North Africa has risen to 460,000 and some 68,000 people were newly infected in 2006 alone. In a bid to curb the region?s growing epidemic, countries have been working with UNAIDS to secure additional funding to scale-up the AIDS response in the region.
Experts in a variety of psychological disciplines have authored articles addressing the present and future of clinical psychology. The articles appear in a special issue of Clinical Psychology: Science and Practice.
Developed countries’ motivation to invest in greenhouse gas emission-reduction projects in developing countries is based on their desire to reduce air pollution they receive from abroad and keep transaction costs down, rather than to achieve global-scale pollution reductions. This analysis1 by Nives Dolsak and Maureen Dunn, from the University of Washington-Bothell, in the US, has been published in Springer’s journal Policy Sciences.
On December 11, USDA Forest Service (FS) scientists from the FS Southern Research Station (SRS) unit in Research Triangle Park, NC, along with colleagues from Duke University, published two papers in The Proceedings of the National Academy of Science (PNAS) that provide a more precise understanding of how forests respond to increasing atmospheric concentrations of carbon dioxide (CO2), the major greenhouse gas driving climate change.
Could low-level heavy metal pollution be combining with warm water temperatures to fatally weaken sea life? A study examining the joint effects of cadmium and temperature on mitochondrial metabolism in oysters finds a combined effect that is potentially lethal and could be a significant contributor to recent oyster declines. The research has broad implications for cold-blooded marine organisms.
Commercial activity permitted in schools, such as soft drink ads; the use of Channel One broadcasts in classrooms; sales incentives from soft drink bottlers; and exclusive beverage contracts may discourage a “nutrition-friendly” environment for students, says researchers.
Hundreds of millions of city dwellers breathe air so polluted with chemicals, smoke and particles that it dramatically exceeds World Health Organization limits with major impacts on health and the environment.
Preliminary findings from a revolutionary satellite system launched earlier this year show that the system can boost the accuracy of forecasts of hurricane behavior, significantly improve long-range weather forecasts, and monitor climate change with unprecedented accuracy. There will be a press conference/teleconference at 5 p.m. Eastern Time today.
Can planting a tree stop the sea level from rising, the ice caps from melting and hurricanes from intensifying?
Carbon dioxide emissions from the burning of fossil fuels will produce a 3 percent reduction in the density of Earth’s outermost atmosphere by 2017, according to a team of scientists from the National Center for Atmospheric Research and Pennsylvania State University.
