WASHINGTON, Dec. 8 – Versatile electronic gadgets should employ a number of important criteria: small in size, quick in operation, inexpensive to fabricate, and deliver high precision output. A new microlaser, developed at the Jožef Stefan Institute in Ljubljana, Slovenia embodies all these qualities. It is small, tunable, cheap, and is essentially the world's first practical three-dimensional laser.

Patients aged 65 and older who survive an episode of mechanical ventilation during a hospitalization are more likely to suffer from long-term disabilities after leaving the hospital than those who survive hospitalization without mechanical ventilation, according to researchers at the University of Pittsburgh. These results were borne out even though the levels of functional disability prior to hospitalization were similar in both groups.
A team of UCSF researchers has engineered E. coli with the key molecular circuitry that will enable genetic engineers to program cells to communicate and perform computations.
HOUSTON -- (Dec. 8, 2010) -- Physicists from Rice University and Princeton University have discovered how to use one of the information technology industry's mainstay materials -- gallium arsenide semiconductors -- as an ultrasensitive microwave detector that could be suitable for next-generation computers. The discovery comes at a time when computer chip engineers are racing both to add nanophotonic devices directly to microchips and to boost processor speeds beyond 10 gigahertz (GHz).
The report "Assessment of Arsenic Concentrations in Domestic Well Water, by Town, in Maine, 2005-09" and maps are posted online.
Potentially harmful arsenic levels have been found in private water wells in towns across Maine where elevated arsenic risks were not previously suspected. Arsenic levels in some private wells exceeded the federal safety standard for public drinking water by ten to one-hundred times or more, according to findings released today by the U.S. Geological Survey. The study is the largest of its kind in Maine.
Home health care technology may provide one important solution to global concerns about how to sustain health care systems threatened by rising costs and manpower shortages, but such a change faces multiple obstacles to adoption, according to a new RAND Corporation study.
The study finds that a wide array of health care stakeholders agree that expanding home-based health tools could give patients a greater ability to self-manage their conditions in partnership with their medical providers, and help improve their health and overall well-being.
The European League Against Rheumatism (EULAR) welcomes the outcomes of yesterday's Council of the European Union (EPSCO Council). In its meeting on 7 December, ministers for health adopted Council Conclusions on chronic diseases, in which the Council calls on Member States and the European Commission to adopt concrete, coordinated measures to tackle chronic diseases in Europe. EULAR is pleased to note that the Council Conclusions reflect many of the recommendations made at the 19 October Presidency conference on Rheumatic and Musculoskeletal diseases.
Catnip, the plant that attracts domestic cats like an irresistible force, has proven 99 percent effective in repelling the blood-sucking flies that attack horses and cows, causing $2 billion in annual loses to the cattle industry. That's the word from a report published in ACS' biweekly Journal of Agricultural and Food Chemistry.
ANN ARBOR, Mich.---Under just the right conditions---which involve an ultra-high-intensity laser beam and a two-mile-long particle accelerator---it could be possible to create something out of nothing, according to University of Michigan researchers.
The scientists and engineers have developed new equations that show how a high-energy electron beam combined with an intense laser pulse could rip apart a vacuum into its fundamental matter and antimatter components, and set off a cascade of events that generates additional pairs of particles and antiparticles.
Los Angeles, CA (December 8, 2010) People who are neurotic often have more difficulty with relationships and marriage. But if neurotic newlyweds have frequent sexual relations, their marital satisfaction is every bit as high as their less neurotic counterparts, according to a study in the current Social Psychological and Personality Science (published by SAGE).
Vitamin A supplements are still an effective way to reduce childhood death and disease. A new study by Cochrane researchers strongly endorses the continuation of vitamin A supplementation programmes, which reduce the incidence of measles and diarrhoea and ultimately save lives.
"Mobility is hugely important in terms of older people being able to remain independent," explains Dr Lynn McInnes. "Reduced mobility can restrict a person's social life as well as limiting their access to shops, leisure and other activities. People fear not being able to look after themselves and being a burden on others. Often a cause of this dependence is a decline in mobility."
The study used innovative methods, such as location awareness technologies for mapping the mobility of the oldest-old members (75 years and over) of an existing 25-year longitudinal study of ageing.
Second-hand smoke increases risk of invasive meningococcal disease in children
Children exposed to second-hand smoke are more likely to get invasive meningococcal disease than children who are not exposed, reports a study from Chien-Chang Lee at the Harvard School of Public Health (Boston, USA) and colleagues published in this week's PLoS Medicine. The authors also found a possible association of second-hand smoke exposure with invasive pneumococcal disease and Haemophilus influenzae type b.
Are you ready for robots in the ER?
A group of computer engineers at Vanderbilt University is convinced that the basic technology is now available to create robot assistants that can perform effectively in the often-chaotic environment of the emergency room. The specialists in emergency medicine at Vanderbilt University Medical Center are enthusiastic about the potential advantages. So, the two groups have formed an interdisciplinary team to explore the use of robotics in this critical and challenging setting.
HOUSTON (Dec. 7, 2010) – Private insurers appear to be more effective in controlling health care spending differences between two Texas cities than Medicare, according to researchers from The University of Texas Health Science Center at Houston (UTHealth) School of Public Health. Researchers found that sharp disparities in per-capita Medicare healthcare spending between McAllen and El Paso were significantly diminished when private insurance paid for health care costs in the under-65 population.
