Discovery in 'pop' science reveals the elegant, complex way bubbles burst Posted: 13 Jun 2010 11:00 AM PDT Scientists believe they have stumbled upon a universal behavior in how bubbles pop that holds as true for suds in a sink as it does for foam in the ocean. Rather than simply vanishing, ruptured bubbles create rings of smaller bubbles in a cascade effect.

Alzheimer’s brain protein may provide target for treating mental retardation Posted: 13 Jun 2010 11:00 AM PDT From the perspective of neuroscientists, Alzheimer's disease and Down syndrome have at least one thing in common: patients with both diseases have an accumulation of ²-amyloid protein in their brains. Scientists now provide evidence that drugs which help reduce the level of ²-amyloid in the brains of Alzheimer's patients may also work to treat mental retardation in Down syndrome.

New species of large blue butterfly discovered Posted: 13 Jun 2010 11:00 AM PDT Scientists have found a new butterfly species in the south of China. It is the first known species of the family of large blue butterflies that lives in mountain forests.

Two-drug phase I trial shows promise in treating late-stage ovarian cancer Posted: 13 Jun 2010 11:00 AM PDT The combination of decitabine and carboplatin appears to improve the outcome of women who have late-stage ovarian cancer, according to researchers.

New microbial genetic system dissects biomass to biofuel conversion Posted: 13 Jun 2010 11:00 AM PDT A research team has developed a powerful new tool that promises to unlock the secrets of biomass degradation, a critical step in the development of cost-effective cellulosic biofuels.

Driving while distracted is a primary-care issue, physician says; Talking or texting behind the wheel is roughly equivalent to driving drunk Posted: 13 Jun 2010 11:00 AM PDT It's time for physicians to talk to patients about driving while distracted, a problem that has risen to the rough equivalence of drunken driving thanks to the proliferation of phones that allow drivers to talk and text, a primary-care physician suggests.

Harbor seals' whiskers as good at detecting fish as echolocating dolphins, researchers find Posted: 13 Jun 2010 05:00 AM PDT Seals use their whiskers to track hydrodynamic trails left by passing fish, but how sensitive are the whiskers? Testing the responses of a seal to trails left by an artificial fin, researchers found that seals can detect trails up 35 seconds after a fin has passed. Fish can cover hundreds of meters in that time, so the whiskers compare well with the performance of echolocating whales and dolphins.

Sense of smell holds the key to diagnosis and treatment in early stage Parkinson's disease Posted: 13 Jun 2010 05:00 AM PDT A fast, simple and noninvasive test of the ability to smell may be an important tool to screen people who are likely to develop Parkinson's disease, in which motor symptoms only become evident at a later stage of the disease.

Obstacles to stem cell therapy cleared Posted: 13 Jun 2010 05:00 AM PDT Researchers in Sweden have come up with a new technique to prevent tumors developing in connection with stem cell transplantations.

Asthma control? We've got an app for that Posted: 13 Jun 2010 05:00 AM PDT An online self-management tool for people with asthma has been shown to significantly improve their ability to reduce their symptoms. Researchers tested the system in 200 adults with asthma, finding significant effects in those whose asthma was either partly controlled or uncontrolled at the beginning of the trial.

Post-traumatic stress disorder associated with dementia among older veterans Posted: 13 Jun 2010 05:00 AM PDT Older veterans with post-traumatic stress disorder (PTSD) appear more likely to develop dementia over a seven-year period than those without PTSD, according to a new study.

Uninsured more likely to die from trauma than patients with insurance, study finds Posted: 11 Jun 2010 05:00 AM PDT Trauma patients without insurance are more likely to die of their injuries from auto accidents and gunshot wounds than privately insured patients with similar injuries, according to findings of an analysis of 193,804 patients in the from 649 facilities in the U.S.
