Hidden Baja undersea park is the world's most robust marine reserve (August 13, 2011) -- A thriving undersea wildlife park tucked away near the southern tip of Mexico's Baja peninsula has proven to be the world's most robust marine reserve in the world, according to a new study. The most striking finding is that fish communities at a depleted site can recover up to a level comparable to remote, pristine sites that have never been fished by humans. ... > full story
Scientists highlight link between stress and appetite (August 13, 2011) -- Researchers have uncovered a mechanism by which stress increases food drive in rats. This new discovery could provide important insight into why stress is thought to be one of the underlying contributors to obesity. ... > full story
If fat dogs are cool, could fat people be, too? (August 13, 2011) -- Fat dogs are cool. And obese people may be, too. That's what new research suggests. ... > full story
Study sheds light on late phase of asthma attacks (August 13, 2011) -- New research explains why around half of people with asthma experience a "late phase" of symptoms several hours after exposure to allergens. ... > full story
Physicists explore the key energy transport process underlying solar energy harvesting (August 13, 2011) -- Physicists have developed an imaging technique that makes it possible to directly observe light-emitting excitons as they diffuse in rubrene, a new material being explored for its extraordinary electronic properties. ... > full story
Social acceptance and rejection: The sweet and the bitter (August 13, 2011) -- For proof that rejection, exclusion, and acceptance are central to our lives, look no farther than the living room, says a psychologist. "If you turn on the television set, and watch any reality TV program, most of them are about rejection and acceptance," he says. ... > full story

Lasers stimulate stem cells and reduce heart scarring after heart attack, study suggests (August 12, 2011) -- New research shows that "shining" bone marrow stem cells with a laser encourages these cells to migrate to the heart to facilitate the healing process. If applied to these cells a few hours after a heart attack, the scarring that weakens the heart muscle can be reduced by up to 80 percent. ... > full story
NASA's asteroid photographer beams back science data (August 12, 2011) -- The Dawn spacecraft has completed a graceful spiral into the first of four planned science orbits during the spacecraft's yearlong visit to Vesta. The spacecraft started taking detailed observations on Aug. 11 at 9:13 a.m. PDT (12:13 a.m. EDT), which marks the official start of the first science-collecting orbit phase at Vesta, also known as the survey orbit. ... > full story
Drug development in the blink of an eye (August 12, 2011) -- The development of drugs for brain-related conditions is not an efficient process. A key reason for this is a lack of preclinical tests that accurately predict drug efficacy and detect unwanted side effects. But now, researchers have developed a new preclinical approach that they hope can be used alongside current strategies to guide more efficient drug development for brain-related conditions. ... > full story
New anti-censorship scheme could make it impossible to block individual Web sites (August 12, 2011) -- A radical new approach to thwarting Internet censorship would essentially turn the whole Web into a proxy server, making it virtually impossible for a censoring government to block individual Web sites. ... > full story
Possible therapeutic target for depression and addiction identified (August 12, 2011) -- Researchers have identified an important part of the pathway through which stress affects mood and motivation for drugs. The finding may prove useful in humans by providing new potential targets for drugs to treat problems related to stress. ... > full story
