Northwestern University scientists have developed new materials that can detect hard radiation, a very difficult thing to do. The method could lead to a handheld device for detecting nuclear weapons and materials, such as a "nuclear bomb in a suitcase" scenario. "The terrorist attacks of 9/11 heightened interest in this area of security, but the problem remains a real challenge," said Mercouri G. Kanatzidis, who led the research. "We have designed promising semiconductor materials that, once optimized, could be a fast, effective and inexpensive method for detecting dangerous ...

CHICAGO (September 12, 2011) – More part-time employment for surgeons, particularly retiring older male or young female surgeons taking time off for their families, may considerably reduce the surgeon shortage in the United States by 2030, according to a study published in the September issue of the Journal of the American College of Surgeons. Opting to work part-time is gaining popularity among Generation X (currently ages 30 through early 40s) and Millennial physicians (currently mid to late 20s) who want to achieve a better work-life balance by working fewer hours ...

Toronto - The health of the pension system is front page news in countries around the world with an ongoing debate on required contribution rates or minimum retirement ages. An equally relevant issue is how efficiently savings invested in pension funds are managed. A paper written by two professors at the University of Toronto's Rotman School of Management points to economies of scale in pension funds as a powerful tool to increase the wealth accumulated for retirement. The largest pension funds -– those that average $37 billion in assets -- outperformed smaller plans ...

A new study published in The Journal of Sexual Medicine reveals that for the first time, stimulation of the vagina, cervix, or clitoris was shown to activate three separate and distinct sites in the sensory cortex. Some sexuality experts have claimed that the major source of genital sensation is from the clitoris, with relatively little sensation produced by vaginal or cervical stimulation. Researchers led by Barry R. Komisaruk, B.S., Ph.D., of Rutgers University, used functional magnetic resonance imaging (fMRI) to map sensory cortical responses to clitoral, vaginal, ...

The panel noted in its report that these nonfluoride ...

PHILADELPHIA - It's no secret that a high-fat diet isn't healthy. Now researchers have discovered a molecular clue as to precisely why that is. Writing in the Journal of Biological Chemistry, Mitchell Lazar, MD, PhD, the Sylvan Eisman Professor of Medicine and director of the Institute for Diabetes, Obesity, and Metabolism at the Perelman School of Medicine at the University of Pennsylvania, and colleagues, describe that mice lacking a gene-expression-controlling enzyme fed a high-fat diet experience rapid thickening of the heart muscle and heart failure. This molecular ...

WASHINGTON – How doctors, nurses and other health care professionals can be better prepared to reduce medical mistakes and improve patient care is the focus of several studies published in a special issue of the American Psychological Association's Journal of Experimental Psychology: Applied. "These studies examine the cognitive issues related to a wide range of important safety problems in various health care scenarios, from hospital operating rooms to young adult education programs about sexually transmitted disease," said Daniel G. Morrow, PhD, of the University of ...

Traffic planners and engineers worry about "black spots" — intersections that experience a high incidence of traffic accidents. But when it comes to designing safer roads, they lack effective tools to determine what turns a junction into a danger zone for cars and pedestrians alike. Now Ph.D. student Gennady Waizman of Tel Aviv University's Geosimulation Lab at the Department of Geography and the Human Environment and Porter School of Environmental Science has developed SAFEPED, a computer simulation that integrates robotics and statistics on driver and pedestrian behavior ...

This press release is available in French. A Montreal-led international team has identified the mutated gene responsible for three forms of leukodystrophies, a group of childhood-onset neurodegenerative disorders. Mutations in this gene were identified in individuals from around the world but one mutation occurs more frequently in French-Canadian patients from Quebec. Published in the September issue of the American Journal of Human Genetics and selected for the Editors' Corner of the journal, the findings are crucial to the development of diagnostic tests and genetic ...

This press release is available in German. Errors in the copying and reading of genes can have very serious consequences. Fortunately human genetic material is available in duplicate as everyone inherits a complete genome from both their mother and father. However, the two genomes are different: researchers refer to the different variants of the gene sequence on the individual chromosomes as "haplotypes" and the complete analysis of the genome requires detailed knowledge of both haplotypes. Scientists at the Max Planck Institute for Molecular Genetics in Berlin have now ...

Researchers at Emory University School of Medicine have identified a new type of potential anticancer drug. The compound, named FOBISIN, targets 14-3-3 proteins, important for the runaway growth of cancer cells. The researchers were using X-rays to see how FOBISIN fits into the clamp-shaped 14-3-3 protein structure. Unexpectedly, the X-rays induced the compound to be permanently bonded to the protein. The finding suggests that compounds like FOBISIN can be used in combination with radiation to trigger potent anticancer activity. The results were published online Sept. ...

A new study by researchers at the Johns Hopkins Center for Injury Research and Policy finds that helicopters that service the drilling platforms and vessels in the Gulf of Mexico crash on average more than six times per year resulting in an average of 5 deaths per year. From 1983 to 2009, 178 crashes resulted in 139 deaths, including 41 pilots and 3 co-pilots. Mechanical failure was the most common cause, leading to 68 crashes (38 percent of the total), followed by bad weather (16 percent of the total). While the challenges such as bad weather and long travel distances ...

Berkeley — Neuroscientists at the University of California, Berkeley, are offering hope to the 10 percent of the population who suffer from tinnitus – a constant, often high-pitched ringing or buzzing in the ears that can be annoying and even maddening, and has no cure. Their new findings, published online last week in the journal Proceedings of the National Academy of Sciences, suggest several new approaches to treatment, including retraining the brain, and new avenues for developing drugs to suppress the ringing. "This work is the most clearheaded documentation to ...

WINSTON-SALEM, N.C. – September 12, 2011 – A year after hospital discharge, the majority of stroke patients are listening to doctor's orders when it comes to taking their prescribed secondary stroke prevention medications, new data out of Wake Forest Baptist Medical Center shows. However, there is room for improvement, according to investigators. "Medication non-compliance is a major risk factor for stroke and heart disease, and we know that non-compliance with stroke prevention medications increases over the year or two after a stroke," said Cheryl D. Bushnell, M.D., ...

LA JOLLA, CA - Oncologists have long sought a powerful "magic bullet" that can find tumors wherever they hide in the body so that they can be imaged and then destroyed. Until recently scientists accepted the notion that such an agent, an agonist, needed to enter and accumulate in the cancerous cells to act. An international research team has now shown in cancer patients that an investigational agent that sticks onto the surface of tumor cells without triggering internalization, an antagonist, may be safer and even more effective than agonists. One of the Salk Institute's ...

COLUMBIA, Mo. –University of Missouri researchers have found evidence that shows those who quit smoking show improvements in their overall personality. "The data indicate that for some young adults smoking is impulsive," said Andrew Littlefield, a doctoral student in the Department of Psychology in the College of Arts and Science. "That means that 18-year-olds are acting without a lot of forethought and favor immediate rewards over long term negative consequences. They might say, 'I know smoking is bad for me, but I'm going to do it anyway.' However, we find individuals ...

With more and more Americans upgrading to smartphones, and as smartphone capabilities continue to improve, even the U.S. government is considering innovative ways to harness this advancing technology. Human factors/ergonomics researchers have evaluated the potential benefits of using smartphones to enable online voting in future U.S. elections and will present their findings at the upcoming HFES 55th Annual Meeting in Las Vegas, Nevada.
