Friends, the mainstream media and the internet, all potentially unreliable sources, continue to be the way America's young adults find their health information. Research has found that while they trust health professionals and health educators, they often do not turn to them for information, especially when it comes to their sexual health. In an attempt to provide a reliable and trustworthy source for reproductive health information for teenagers, one physician-researcher at Women & Infants Hospital of Rhode Island has launched the website Ask A Doc RI. "My thought ...

New research from the 2011 "Portrait of American Travelers" by the YPartnership / Harrison Group this summer identifies ongoing travel movement by multiple generations of U.S. families as the leading driver of leisure travel activity. The March 2011 survey polled 2,539 U.S. households with annual incomes of $50,000 or more who took a leisure trip of 75 miles or more requiring overnight accommodations in the previous 12 months. Among the findings were that seven in 10 leisure travelers (70%) took a "celebration vacation" to mark a "life event," ...

Researchers from the University of Notre Dame in Indiana have harnessed another one of graphene’s remarkable properties to better control a relatively untamed portion of the electromagnetic spectrum: the terahertz band. Terahertz radiation offers tantalizing new opportunities in communications, medical imaging, and chemical detection. Straddling the transition between the highest energy radio waves and the lowest energy infrared light, terahertz waves are notoriously difficult to produce, detect, and modulate. Modulation, or varying the height of the terahertz waves, is ...

A simplified mathematical model of the brain’s neural circuitry shows that repetitious, overlapped firing of neurons can lead to the waves of overly synchronized brain activity that may cause the halting movements that are a hallmark of Parkinson’s disease. The model provides a tool in the quest to gain a better understanding of the mechanisms behind this incurable degenerative disorder. Researchers from IUPUI (Indiana University-Purdue University Indianapolis) reduced the complex biology of the basal ganglia, a part of the brain involved in voluntary motor control, down ...

Legend tells of Greek engineer and inventor Archimedes using parabolic mirrors to create “heat rays” to burn the ships attacking Syracuse. Though the underpinnings of that claim are speculative at best, a modern-day team of researchers at the Scientific and Production Association in Uzbekistan has proposed a more scientifically sound method of harnessing parabolic mirrors to drive solar-powered lasers. Small scale analogs of giant reflector telescopes, these proposed ceramic lasers would convert an impressive 35 percent of the Sun’s energy into a laser light, providing ...

EAST LANSING, Mich. — There are many old wives' tales about what determines a baby's sex, yet it is the tight controls at the gene level that determine an organism's sex in most species. Researchers at Michigan State University have found that even when genetic and genomic mechanisms are disrupted, organisms quickly evolve ways to compensate. In research published this week in Evolution, scientists from MSU's BEACON Center for the Study of Evolution in Action led a team of researchers using an experimental evolution approach to study adaptations in sexual determination ...

Higher flu vaccination rates for health care personnel can dramatically reduce the threat of flu outbreak among nursing home residents, according to a study published in the October issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America. The study, which focused on nursing homes in New Mexico, found that when a facility had between 51 and 75 percent of its health care personnel with direct patient care vaccinated, the chances of a flu outbreak in that facility went down by 87 percent. "The Centers for ...

A study published in the October issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America, uses a famous case of international intrigue and murder to shed new light on the risks health care workers face while treating patients with radiation poisoning. The study focused on hospital staff involved in the care of Alexander Litvinenko, the Russian dissident and former KGB operative who died from Polonium-210 poisoning in a London hospital in 2006. While who poisoned Litvinenko remains unknown, public health ...

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, ...

CHICAGO, Sept. 12, 2011 – A multi-disciplinary expert panel, convened by the American Dental Association (ADA) Council on Scientific Affairs, issued a report this month containing clinical recommendations that sugar-free chewing gum, lozenges and hard candy including xylitol or polyol combinations, and a prescription varnish with chlorhexidine and thymol could be beneficial in preventing cavities when used as adjuncts to a comprehensive cavity prevention program which includes the use of fluoride-containing products. 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. ...
