HIV :: Early-stage immune system control of HIV may depend on inherited factors

How well an individual’s immune system controls HIV during the earliest phases of infection appears to depend on both the specific versions of key immune-system molecules called HLA Class I that have been inherited, as well as on the fragments of viral protein those molecules display to the T lymphocytes that usually destroy infected cells. In a report in the November issue of PLOS Medicine, researchers from the Partners AIDS Research Center at Massachusetts General Hospital (PARC/MGH) report that specific HLA Class I/HIV viral fragment combinations are associated with a more powerful antiviral response, findings that may help develop vaccines against HIV.

Health :: Park your car and walk to store, school, work

New Saint Louis University research that outlines the top 10 factors that encourage people to be physically active is a blueprint to design healthier communities.

Health :: Space sunshade might be feasible in global warming emergency

Developing renewable energy is the only permanent solution to global warming, University of Arizona astronomer Roger Angel concludes. But should Earth be faced with an abrupt climate crisis, a space sunshade is a technically feasible solution.

Education :: Giving hope back to disabled veterans

Kent State University, in partnership with the Louis Stokes Cleveland Department of Veteran Affairs Medical Center, has created a program that offers veterans the opportunity to take control of their future by obtaining entirely online degrees suited to their educational, physical and mental needs.

Nutrition :: Research addressing malnutrition and iron deficiency

Dartmouth biologists are leading a research team that has learned where and how some plant seeds store iron, a valuable discovery for scientists working to improve the iron content of plants. This research helps address the worldwide issue of iron deficiency and malnutrition. Their findings were published online on Nov. 2 at ScienceExpress, the advance publication site for the journal Science.

Health :: Teenagers know about condoms … so why don’t they use them?

A review of research has revealed striking similarities in the influences on young people’s sexual behavior across the world. The review of qualitative studies, published today in the Lancet, looked at 268 studies of the sexual behavior of under-25-year-olds from South Africa to Sweden. It reveals how, in all countries, social expectations of how men and women should behave frustrate campaigners’ efforts to encourage safer sex.

Health :: First global analysis of sexual behavior

A groundbreaking study, which provides the first ever comprehensive analysis of sexual behaviour around the world, is published today in the Lancet, as part of a major series on sexual and reproductive health.

Eyes :: Funnel in the eye: Signal focusing increases photosensitivity

In poor light the eyes of mice react like some digital cameras: they reduce their resolution while at the same time increasing their sensitivity. Specialists in the retina focus the information of several light sensor cells for this purpose. Scientists from the University of Bonn and their colleagues from Oldenburg, Bochum and Kobe (Japan), have now discovered how all this works. The study will be published on 3 November in the prestigious Journal of Biological Chemistry.

Backache :: Backache beaten by good vibrations?

University of Manchester researchers are recruiting people with backache caused by nerve root pain — commonly known as sciatica — in the first ever study to discover if therapeutic ultrasound can help their condition.

Psychology :: Iraqi people likely to suffer psychological damage

Exposure to violence is putting the people of Iraq at risk of serious psychological damage, says a doctor in this week’s BMJ.Previous studies have suggested that the risk of developing post-traumatic stress disorder following a traumatic event ranges from 7.5 percent to 72 percent, with the risk being highest in those exposed to sustained combat trauma.
