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.
A leading population expert will today make a plea for a revitalization of the family planning agenda in the world’s poorest countries, cautioning that soaring population rates are now a bigger threat to achieving the MDGs than HIV/AIDS.
Scientists at the Scripps Research Institute have found that reducing the core body temperature of mice extends their median lifespan by up to 20 percent. This is the first time that changes in body temperature have been shown to affect lifespan in warm-blooded animals.
In the November 15th issue of G&D, Dr. Robert Schneider and colleagues at NYU School of Medicine report that the AUF1 gene underlies susceptibility to septic shock.
In the November 15th issue of G&D, Dr. Sriharsa Pradhan (New England Biolabs) and colleagues demonstrate that the DNA methyltransferase, DNMT1, and the histone methyltransferase, G9a, interact to coordinate DNA and histone methylation during DNA replication.
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.
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.
A breakthrough in the harnessing of “T-rays” — electromagnetic terahertz waves — which could dramatically improve the detecting and sensing of objects as varied as biological cell abnormalities and explosives has been announced by a team led by the University of Bath.
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.
Doctors should probably stop using pulmonary artery catheters because they do not benefit patients, say doctors from Australia in this week’s BMJ.
