Twitter ScienceDaily (Oct. 27, 2011) — Official assessments of a doctor's professionalism should be considered carefully before being accepted due to the tendency for some doctors to receive lower scores than others, and the tendency of some groups of patient or colleague assessors to provide lower scores, claims new research published online in the British Medical Journal.Researchers from the Peninsula College of Medicine and Dentistry in Exeter investigated whether there were any potential patient, colleague...

ScienceDaily (Oct. 28, 2011) — A team of researchers at MIT has found one of the most effective catalysts ever discovered for splitting oxygen atoms from water molecules -- a key reaction for advanced energy-storage systems, including electrolyzers, to produce hydrogen fuel and rechargeable batteries. This new catalyst liberates oxygen at more than 10 times the rate of the best previously known catalyst of its type.The new compound, composed of cobalt, iron and oxygen with other metals, splits...

ScienceDaily (Oct. 27, 2011) — A team of computer scientists, physicists, and physicians at Harvard has developed a simple yet powerful method of visualizing human arteries that may result in more accurate diagnoses of atherosclerosis and heart disease.The prototype tool, called "HemoVis," creates a 2D diagram of arteries that performs better than the traditional 3D, rainbow-colored model. In a clinical setting, the tool has been shown to increase diagnostic accuracy from 39% to 91%.Presented Oct....

ScienceDaily (Oct. 27, 2011) — People who use over-the-counter "thyroid support'' supplements may be putting their health at risk, according to a study being presented at the annual meeting of the American Thyroid Association. The supplements contain varying amounts of two different kinds of thyroid hormones apparently derived in large part from chopped up animal thyroid glands, says the study's senior investigator, Victor Bernet, M.D., an endocrinologist at Mayo Clinic in Florida.The hormones...

ScienceDaily (Oct. 27, 2011) — Using highly potent antibodies isolated from HIV-positive people, researchers have recently begun to identify ways to broadly neutralize the many possible subtypes of HIV. Now, a team led by biologists at the California Institute of Technology (Caltech) has built upon one of these naturally occurring antibodies to create a stronger version they believe is a better candidate for clinical applications.Current advances in isolating antibodies from HIV-infected individuals...

ScienceDaily (Oct. 27, 2011) — Today's multicore processors are not being utilized in a sufficiently intelligent way. They get too hot and run slowly because they are used inefficiently. At the same time, transistors are becoming so small that they will ultimately become unreliable. Major European research organizations are now attempting to create a revolution in computer architecture.Are you disappointed with the performance of your new computer or phone? Then perhaps rightly so. Their clock...
