The so-called "Khmer Rouge trials," now underway, are likely to have an impact on the mental health of many Cambodians, according to a new study published in JAMA.

African village dogs are not a mixture of modern breeds, but have directly descended from an ancestral pool of indigenous dogs, according to a Cornell-led genetic analysis of hundreds of semi-feral African village dogs.

That means that village dogs from most African regions are genetically distinct from non-native breeds and mixed-breed dogs. They also are more genetically diverse because they have not been subjected to strict breeding, which artificially selects genes and narrows breeds' gene pools.

A 2006 report by sociologists Miller McPherson, Lynn Smith-Lovin and Matthew E. Brashears found a near tripling in reports of Americans' social isolation between 1985 and 2004. The percentage who said they did not discuss important matters with any one qualified as "socially isolated".

Three cases of patients suffering from the adverse affects of steroid-enriched dietary supplements have been reported by researchers at Henry Ford Hospital. The cases, which include patients with liver injury and renal failure, are discussed in the The Journal of Clinical Gastroenterology.

The U.S. Food and Drug Administration last week issued a warning regarding the use of over-the-counter body-building supplements that are illegally enriched with anabolic steroids.

Your office or firm might not own –– or be able to afford –– the latest software or computers. But that may not impair the productivity of your workers, concludes a new Tel Aviv University study.

The new research field of synthetic biology will, in the medium term, open up a great deal of potential for combining novel genetic methods with engineering principles. This will facilitate the development, not only of new vaccines and medicines, but also of fuels and new materials. Early-stage dialogue with the public on the natural science, legal, economic and ethical issues is crucial for the success and acceptance of this new technology.

WEST LAFAYETTE, Ind. - Research findings suggest that, contrary to popular belief, engineering does not have a higher dropout rate than other majors and women do just as well as men, information that could lead to a strategy for boosting the number of U.S. engineering graduates.

Toronto -- Years of research suggest that the promises organizations make to employees matter in establishing and maintaining a "psychological contract" between the two parties. However, new research by Samantha Montes and co-author David Zweig, professors at the University of Toronto's Rotman School of Management and the University of Toronto Scarborough, suggests that what an organization promises to employees (e.g., training opportunities, benefits, compensation) don't matter nearly as much as what the organization actually delivers.

CINCINNATI—Although lead content in paint has been restricted in the United States since 1978, University of Cincinnati (UC) environmental health researchers say in major countries from three continents there is still widespread failure to acknowledge its danger and companies continue to sell consumer paints that contain dangerous levels of lead.

An analysis of back issues of the popular US magazine, Parents, maps how the portrayal of parental authority and children's autonomy has changed over the last century. The findings are published online in journal Qualitative Sociology and say that kids only have more autonomy inside the home but are more restricted outside.

Advances in ecology increasingly reveal that conventional agricultural practices have detrimental effects on the landscape ecology, creating problems for long-term sustainability of crops. In a series of sessions at the Ecological Society of America's Annual Meeting, ecologists will present their ideas on how our agricultural practices can take lessons from natural environments.

The team led by a University of Washington researcher has used computers to extract patterns in ancient Indus symbols. The study, published in the Proceedings of the National Academy of Sciences, shows distinct patterns in the symbols' placement in sequences and creates a statistical model for the unknown language.

Heart disease patients with previous atherosclerosis (fat deposits in the walls of the arteries) are more likely to die in the hospital and less likely to be treated with recommended therapies, researchers report in Circulation: Journal of the American Heart Association.

A school-based program that integrates information about healthy relationships into the existing ninth-grade curriculum appears to reduce adolescent dating violence and increase condom use two and a half years later, according to a report in the Archives of Pediatrics & Adolescent Medicine.

Taking opioid drugs without a prescription appears relatively common among high school seniors, according to a report in the Archives of Pediatrics & Adolescent Medicine. The most common reasons survey respondents gave for taking the medications included relaxing, feeling good or getting high, experimenting, and relieving pain
