Overturning more than 40 years of accepted practice, new research proves that the tools used to check tests of "general mental ability" for bias are themselves flawed. This key finding challenges reliance on such exams to make objective decisions for employment or academic admissions even in the face of well-documented gaps between mean scores of white and minority populations.

New study: Tools that assess bias in standardized tests are flawed
Posted by eurekalert 3 hours ago (http://www.eurekalert.org)
Researchers seeking to learn more about stroke by studying how the body responds to toxins in snake venom are this week releasing new findings that they hope will aid in the development of therapies for heart disease and, surprisingly, cancer.
Hockey fans likely would assume that body-checking -- intentionally slamming an opponent against the boards -- causes the most injuries in youth ice hockey. But they would be wrong.
Empa grows 'sea urchin'-shaped structures
Posted by eurekalert 21 hours ago (http://www.eurekalert.org)
Empa researchers have succeeded in growing sea-urchin shaped nanostructures from minute balls of polystyrene beads using a simple electrochemical process. The spines of the sea urchin consist of zinc oxide nanowires. The structured surface should help increasing the efficiency of photovoltaic devices.

Physicists from Rice University, the Max Planck Institute and the Vienna University of Technology are reporting new results from experiments on the perplexing class of materials that includes high-temperature superconductors. In this week's Proceedings of the National Academy of Science, the team reports the unexpected discovery of a simple fractal form of electronic excitations in ultra-low-temp
Nearly 1 in 5 Californians report need for mental health services, study finds
Posted by eurekalert 1 day 15 hours ago (http://www.eurekalert.org)
A comprehensive new study of mental health status and use of mental health services in California by the UCLA Center for Health Policy Research found that nearly 1 in 5 adults in California, about 4.9 million persons, said they needed help for a mental or emotional health problem. Additionally, approximately 1 in 25, or over one million Californians, reported symptoms associated with serious psy
One molecule, many more insulin-producing cells to treat diabetes, says Pitt team
Posted by eurekalert 1 day 21 hours ago (http://www.eurekalert.org)
With a single stimulatory molecule, human insulin-producing beta cell replication can be sustained for at least four weeks in a mouse model of diabetes, according to researchers at the University of Pittsburgh School of Medicine in Diabetes. They also found several cocktails of molecules that drive human beta cells to replicate, as well as important differences between mouse and human beta cells
