WASHINGTON, Dec. 6—Recent progress in chalcogenide glass photonics has been driven by scientific and technological challenges in a variety of areas. These range from increased demand for bandwidth in optical communications, to the emergence of bio-health hazards associated with hazardous microorganisms that absorb at mid-infrared wavelengths, to defense applications that require bright mid-infrared sources.
What: Scientists from the National Institutes of Health have discovered how catheter-related bacterial infection develops and disseminates to become a potentially life-threatening condition. The study, which included research on Staphylococcus epidermidis in mice implanted with catheters, could have important implications for understanding many types of bacterial biofilm infections, including those caused by methicillin-resistant S. aureus (MRSA).
CORVALLIS, Ore. – It's illegal for businesses and law enforcement to profile a person based on their race, gender, or ethnicity, yet millions of Americans are being profiled every day based on their online consumer behavior and demographics.
Known as consumer profiling for behavioral advertising purposes, this type of profiling is largely unregulated.

Brand named hotels fare better than independently operated properties in economic downturns, according to a team of international researchers.

Personality is not just a feature unique to humans and pets. Scientists at the University of Gothenburg (Sweden) have revealed that also brown trout have individual characters and show different personalities.
Researcher Bart Adriaenssens from the Department of Zoology at the University of Gothenburg has for many years studied the behaviour of juvenile trout from watercourses on the west coast of Sweden.
Tel Aviv ― Naukrtis, a Greek trade emporium on Egyptian soil, has long captured the imagination of archaeologists and historians. Not only is the presence of a Greek trading settlement in Egypt during the 7th and 6th century B.C.E. surprising, but the Greeks that lived there in harmony hailed from several Greek states which traditionally warred amongst themselves.
New research led by economists at the University of Warwick reveals that medieval England was not only far more prosperous than previously believed, it also actually boasted an average income that would be more than double the average per capita income of the world's poorest nations today.
Lesbian, gay and bisexual (LGB) adolescents are about 40 percent more likely than other teens to be punished by school authorities, police and the courts, according to a study by Yale University researchers. Published in the January 2011 issue of the journal Pediatrics, the study is the first to document excessive punishment of LGB youth nationwide.
INDIANAPOLIS – The most frequent contributors to medication errors and adverse drug events in busy primary care practice offices are communication problems and lack of knowledge, according to a study of a prototype web-based medication error and adverse drug event reporting system.
Research on the use of MEADERS (Medication Error and Adverse Drug Event Reporting System), developed by investigators from the Regenstrief Institute and Indiana University School of Medicine led by Atif Zafar, M.D., appears in the November/December 2010 issue of the Annals of Family Medicine.
A new report recently released by the National Science Foundation, titled "Doctorate Recipients from U.S. Universities: 2009," presents a statistical overview of the U.S. doctoral education system in snapshots and long-term trends.
It notes the American system of doctoral education is widely considered the world's best, as evidenced by the large number of international students who choose to pursue a doctorate at U.S. universities. But this status is subject to the many factors that shape U.S. doctoral education.
The Earth has run out of room to expand fisheries, according to a new study led by University of British Columbia researchers that charts the systematic expansion of industrialized fisheries.
November 30, 2010 -- Despite the existence of effective programs for treating alcohol dependencies and disorders, less than a quarter of people who are diagnosed actually seek treatment. In a recent study by Columbia University's Mailman School of Public Health researchers report that people diagnosed with alcoholism at some point in their lifetime were more than 60% less likely to seek treatment if they believed they would be stigmatized once their status is known.
With almost one billion people lacking access to clean, safe drinking water, scientists are reporting development and successful initial tests of an inexpensive new filtering technology that kills up to 98 percent of disease-causing bacteria in water in seconds without clogging. A report on the technology appears in Nano Letters, a monthly American Chemical Society journal.
Experiences with violence cause teens growing up in dangerous neighborhoods to adopt a range of coping strategies, with notable impact whether the violence takes place at home, among friends or during police incidents, a University of Chicago study shows.
The responses to violence include seeking out non-violent friends, avoiding trouble, becoming resigned to the situation, striving to do well in school, or for some, retaliating physically, the authors said.
