String blossom thinner proves effective across stages of bloom development

BIGLERVILLE, PA—Blossom or fruitlet thinning is a labor-intensive part of commercial peach and nectarine production. The use of mechanical string blossom thinners has been shown to reduce labor requirements and improve fruit size in peach crops, but stone fruit producers have needed more information about the range of thinning times. New research from Tara Auxt Baugher and colleagues from The Pennsylvania State University and Penn State Cooperative Extension gives producers sought-after data about optimum thinning times.

ATS issues report recommending research priorities in treatment of sleep apnea

The American Thoracic Society has released a new official report recommending research priorities in incorporating ambulatory management of adults with obstructive sleep apnea (OSA) into healthcare systems. The report identifies barriers preventing incorporation of portable monitor testing into clinical management pathways and recommends research and development needed to address those barriers.

The statement appears in the March 1, 2011, issue of the Proceedings of the American Thoracic Society.

College students surveyed on guns on campus

HUNTSVILLE -- Students from two university campuses in Texas and Washington recently were surveyed on allowing concealed handguns on campus.

According to research led by Dr. Jeffrey Bouffard at Sam Houston State University's College of Criminal Justice, more students were uncomfortable with concealed weapons on campus than those at ease with guns on college grounds. The study will be presented at the Academy of Criminal Justice Sciences Meeting in Toronto this month.

For birds, the suburbs may not be an ideal place to raise a family

There comes a time in life for every bird to spread its wings and leave the nest, but for gray catbirds, that might be the beginning of the end. Smithsonian scientists report fledgling catbirds in suburban habitats are at their most vulnerable stage of life, with almost 80 percent killed by predators before they reach adulthood. Almost half of the deaths were linked to domestic cats.

Student innovation at Rensselaer Polytechnic Institute could lead to better breast cancer screening

Troy, N.Y. – Recent research by doctoral student Sevan Goenezen holds the promise of becoming a powerful new weapon in the fight against breast cancer. His complex computational research has led to a fast, inexpensive new method for using ultrasound and advanced algorithms to differentiate between benign and malignant tumors with a high degree of accuracy.

Grazing of cattle pastures can improve soil quality

A team of U.S. Department of Agriculture (USDA) scientists has given growers in the Piedmont guidance on how to restore degraded soils and make the land productive. Researchers with the USDA's Agricultural Research Service (ARS) found that if cattle are managed so that they graze moderately, soil quality can be restored and emissions of carbon dioxide (a greenhouse gas) can be reduced.

6 out of 10 male drug-addicts abuse their partners, a study says

and Spanish.

According to a study conducted at the Department of Pedagogy of the University of Granada, about six out of ten male drug-abusers direct some type of violence against their intimate partners. Thus, the study revealed a high rate of domestic violence –both pysical and psychological– by male drug-abusers against women. The study also detailed the most recurrent forms of abuse, as well as the variables associated to them.

Study finds MRSA danger in gyms may be exaggerated

Washington, DC, March 3, 2011 – Community gym surfaces do not appear to be reservoirs for MRSA transmission, according to a study published in the March issue of the American Journal of Infection Control, the official publication of APIC – the Association for Professionals in Infection Control and Epidemiology.

The UK maintains a positive outlook, despite the recession

More than 15,000 adults of working age took part in the survey for Understanding Society, the world largest household panel study funded by the Economic and Social Research Council and run by the Institute of Social and Economic Research (ISER) at the University of Essex. The survey which will follow 40,000 UK households over many years, asks people about a wide range of topics including their employment status, families, income levels and well-being.

Nanofabrication tools may make silicon optical chips more accessible

In an effort to make it easier to build inexpensive, next-generation silicon-based electro-optical chips, which allow computers to move information with light and electricity, a University of Washington photonics professor, Dr. Michael Hochberg and his research team are developing design tools and using commercial nanofabrication tools.

Silicon optical chips are critical to the Air Force because of their size, weight, power, rapid cycle time, program risk reduction and the improvements they can offer in data communications, lasers and detectors.

Study in PLoS: Intensive adherence counseling to HIV treatment improves patient outcomes

Intensive adherence counseling around the time of HIV treatment initiation significantly reduces poor adherence and virologic treatment failure in sub-Saharan Africa, according to a recent study in PLoS Medicine by Dr. Michael Chung, assistant professor of Global Health at University of Washington, who works at the Coptic Hope Center for Infectious Diseases in Nairobi, Kenya.

The study published March 1 also found that using an alarm device has no effect on adherence counseling.

An appeal to the caregiving values of rural women for breast cancer prevention

KNOXVILLE, TN —March 2, 2011 — In an effort to develop strategies for breast health awareness in rural populations researchers asked the question, "What message strategies will motivate Appalachian women to attend to breast health issues and become actively involved in their own breast health?" A new study published in the Journal of Consumer Affairs finds that two types of reasons motivate rural Appalachian women to perform breast health self-examinations, get mammograms, and to talk with doctors about their breast health.

Hair dyeing poised for first major transformation in 150 years

Technological progress may be fast-paced in many fields, but one mundane area has been almost left in the doldrums for the last 150 years: The basic technology for permanently coloring hair. That's the conclusion of an analysis of almost 500 articles and patents on the chemistry of permanent hair dyeing, which foresees much more innovation in the years ahead, including longer lasting, more-natural-looking dyes and gene therapy to reverse the gray. The article appears in ACS's journal Chemical Reviews.

Sustaining the biodiversity of the western Great Plains

Fire, cattle and even prairie dogs all could play a role in sustaining the biodiversity of the western Great Plains, according to a U.S. Department of Agriculture (USDA) researcher.

Sugarcane bioethanol: Environmental implications

Researchers have long promoted biofuels produced from crop biomass as an environmentally sustainable source of renewable energy. A recent study questions whether the potential climate benefit of sugarcane ethanol is diminished when emissions from land use management are considered.

Scientists examined the sugarcane ethanol production systems to identify sources of greenhouse gas emissions. They found that land use change, fertilization, residue burning, and tillage had the largest impact on greenhouse gas emissions.
