London, UK (November 1, 2010) – In April 2010, the US government adopted a new nuclear strategy that depends on the conclusion that the current missile defense systems will reliably protect the continental United States in the extreme circumstances of nuclear-armed combat. Now research in the Bulletin of Atomic Scientists, published by SAGE, shows that these defenses have not been tested against real-world threats and would not be effective in real combat conditions.

Alexandria, VA — Racial and ethnic disparities among children with frequent ear infections (FEI) significantly influence access to affordable healthcare, according to new research published in the November 2010 issue of Otolaryngology – Head and Neck Surgery.

Ear infections are one of the most common health problems for children, with most kids experiencing at least one by their third birthday. Annual costs in the United States alone are in the billions of dollars.

SEATTLE--Primary-care clinicians know teen depression is common, but they've lacked a reliable screening test for it. Now researchers at the University of Washington (UW), Seattle Children's, and Group Health report the PHQ-9 (Patient Health Questionnaire - 9 item) is a good screening test for major depression in adolescents.

LAWRENCE, Kan. – A little self-awareness can help people struggling in the world of relationships, says Jeffrey Hall, assistant professor of communication studies at the University of Kansas.

Hall recently completed a study into styles of flirting among dating adults, surveying more than 5,100 people regarding their methods of communicating romantic interest.

Researchers have developed an efficient method for extracting and archiving CT radiation dose information that can enable providers to keep track of estimated radiation dose delivered to each patient at a given facility, help providers make more informed health care decisions and improve patient safety, according to a study in the November issue of the Journal of the American College of Radiology (www.jacr.org).

An overwhelming majority of Breast Cancer Surveillance Consortium (BCSC) facilities performing breast magnetic resonance imaging (MRI) in the U.S. are up-to-par with American College of Radiology Imaging Network (ACRIN) and European Society of Breast Imaging (EUSOBI) technical standards and requirements, according to a study in the November issue of the Journal of the American College of Radiology (www.jacr.org). The BCSC is a collaborative effort to improve breast cancer research.

CORVALLIS, Ore. – Researchers at Oregon State University have solved a quest in fundamental material science that has eluded scientists since the 1960s, and could form the basis of a new approach to electronics.

The discovery, just reported online in the professional journal Advanced Materials, outlines the creation for the first time of a high-performance "metal-insulator-metal" diode.

The decision to stop life-support for incapacitated and critically ill patients is, for surrogate decision makers, often fraught with moral and ethical uncertainty, and long-term emotional consequences. But as difficult as these decisions are, more than half of surrogate decision makers prefer to have full authority over the choice than to share or cede that power to physicians, according to a recent study out of the University of Pittsburgh School of Medicine.

Extra-virgin olive oil can protect the liver from oxidative stress. Researchers writing in BioMed Central's open access journal Nutrition and Metabolism exposed rats to a moderately toxic herbicide known to deplete antioxidants and cause oxidative stress, finding that those rats fed on a diet containing the olive oil were partially protected from the resulting liver damage.

A University of Alberta geomicrobiologist and his PhD student are part of a research team that has identified phosphorus as the mystery ingredient that pushed oxygen levels in the oceans high enough to establish the first animals on Earth 750 million years ago.

URBANA – Finding good child care and being able to engage easily in important interactions with your child care provider are critical to any mother's ability to work outside the home.

"Suppose you're living in the rural Midwest and you don't speak English very well. Can you imagine leaving your child with a child care provider if you couldn't communicate well with that person?" said Angela Wiley, a University of Illinois associate professor of applied family studies.

"The immigrant moms we interviewed for this study faced just this dilemma," she said.

PHILADELPHIA — Researchers have identified two small-molecule inhibitors that effectively targeted the focal adhesion kinase (FAK), an enzyme present in certain cancers that helps tumors thrive and survive.

If the drugs are developed into oral therapeutic agents in the future, they could open up the potential for more effective and less toxic cancer therapies, according to research presented at The American Association for Cancer Research special conference on Colorectal Cancer: Biology to Therapy, held Oct. 27-30, 2010.

Race may not be as important as previously thought in determining who buddies up with whom, suggests a new UCLA–Harvard University study of American college students on the social networking site Facebook.

Millions of Medicare recipients have been forcibly reassigned to different prescription drug plans because Part D reimbursements to insurance companies covering low-income patients are lower than the actual costs incurred, according to a study released online today by Health Affairs. The report describes how a system designed to encourage competition and to subsidize care for low-income Medicare patients instead has led companies to raise their premiums in an effort to price themselves out of the low-income segment of the Part D market.
