HOUSTON – Forty-five percent of women with advanced breast cancer in the U.S. did not receive postmastectomy radiation therapy (PMRT) despite the publication of evidence-based guidelines outlining PMRT as a potentially lifesaving treatment, according to new research from The University of Texas MD Anderson Cancer Center.

Most parents are unaware of the risks their teenagers face in the workplace and could do more to help them understand and prepare for those hazards, according to a new study.
Previous findings have shown that about 80 percent of teens are employed during their high school years. But the study from the University of North Carolina at Chapel Hill's Injury Prevention Research Center and North Carolina State University highlights the role parents play in helping their children get those jobs, and making good decisions about workplace safety and health.
NEW YORK (June 27, 2011) – A new survey conducted by WCS scientists, supported by the U.S. Agency for International Development (USAID), reveals that large mammals, including Asiatic black bears, gray wolves, markhor goats, and leopard cats are surviving in parts of Afghanistan after years of conflict.
Gold nanoparticles are becoming the … well … gold standard for medical-use nanoparticles. A new paper* by researchers from the National Institute of Standards and Technology (NIST) and the National Cancer Institute's Nanotechnology Characterization Laboratory (NCL) proposes not only a sort of gold nanoparticle "testbed" to explore how the tiny particles behave in biological systems, but also a paradigm for how to characterize nanoparticle formulations to determine just what you're working with.
DURHAM, N.C. – Cancer cells circulating in the blood carry newly identified proteins that could be screened to improve prognostic tests and suggest targets for therapies, report scientists at the Duke Cancer Institute.
Building on current technologies that detect tumor cells circulating in blood, the Duke team was able to characterize these cells in a new way, illuminating how they may escape from the originating tumors and move to other locations in the body.
Saranac Lake, N.Y. – Researchers from the Smiley lab at the Trudeau Institute have now identified a single component of the plague causing bacterium that can be used as a vaccine. This single "subunit" could potentially be used to create a safer form of a T cell-stimulating plague vaccine. The new data is featured in the July issue of The Journal of Immunology.
Herpes infections on the lips, in the eyes or on the nose are painful, long-lasting and unpleasant. A new 3-D herpes infection model brings hope: active ingredients and new treatments can be reliably tested with this model. Animal tests could soon be a thing of the past.
The Royal College of Psychiatrists of London has published a report related primarily to problems of unrecognized alcohol misuse among the elderly. The report provides guidelines for psychiatrists and family physicians on how to find and how to treat elderly people with misuse of alcohol and drugs. Forum members consider it very important to identify abusive drinking among the elderly and this report provides specific and very reasonable recommendations to assist practitioners in both the identification and treatment of such problems.
Development of disease resistance among Chesapeake Bay oysters calls for a shift in oyster-restoration strategies within the Bay and its tributaries. That's according to a new study by researchers at the Virginia Institute of Marine Science (VIMS).
The study, by professors Ryan Carnegie and Eugene Burreson, is the feature article in the most recent issue of Marine Ecology Progress Series. It is based on 50 years of VIMS research into the prevalence of MSX disease among the native eastern oyster Crassostrea virginica.
WINSTON-SALEM, N.C. – June 27, 2011-- All fat is not created equal. Unsightly as it is, subcutaneous fat, the fat right under the skin, is not as dangerous to overall health as visceral fat, the fat deep in the belly surrounding vital organs.
According to a new study by researchers at Wake Forest Baptist Medical Center, the way to zero in and reduce visceral fat is simple: eat more soluble fiber from vegetables, fruit and beans, and engage in moderate activity.
A team of researchers from the National Institute of Standards and Technology (NIST), George Mason University and the University of Maryland has made nano-sized sensors that detect volatile organic compounds—harmful pollutants released from paints, cleaners, pesticides and other products—that offer several advantages over today's commercial gas sensors, including low-power room-temperature operation and the ability to detect one or several compounds over a wide range of concentrations.
Dr Frank McKeon, Senior Group Leader of the Stem Cell and Developmental Biology at A*STAR's Genome Institute of Singapore (GIS), and Principal Investigator Dr Wa Xian at A*STAR's Institute of Medical Biology (IMB), together with their counterparts from the Harvard Medical School, the Brigham and Women's Hospital in Boston, and the National University of Singapore, have made the striking finding that Barrett's esophagus[1] work, published online in the journal Cell on 24 June 2011, is essential to developing therapeutics for esophageal cancer., the precursor of the most deadly esophag
Babies born prematurely could be at greater risk of developing kidney diseases later in life according to a landmark study investigating the impacts of preterm birth on kidney development.
The Monash University study is identifying new strategies for minimising the consequences of being born preterm, which accounts for around eight per cent of births each year in Australia.
Scientists have tested a predatory bacterium – Bdellovibrio – against Salmonella in the guts of live chickens. They found that it significantly reduced the numbers of Salmonella bacteria and, importantly, showed that Bdellovibrio are safe when ingested.
A recently completed aerial survey of northern Botswana by Elephants Without Borders (EWB), through the support of Botswana's Dept. of Wildlife & National Parks, indicates that wildebeest, giraffes, kudu, lechwe, ostriches, roan and tsessebe antelope and warthog species are significantly challenged. Populations of these species appear to have dropped significantly over the past 15 years, specifically in Ngamiland, which encompasses the Okavango delta.
