Scientists Discover How An Injured Embryo Can Regenerate Itself (June 27, 2008) -- Scientists have developed a mathematical model to describe interactions that occur within genetic networks of an embryo, answering the age-old question of how half embryos are able to maintain their tissues and organs in the correct proportions despite being smaller than a normal sized embryo. Understanding the processes that govern embryonic cell development, may lead, in the future, to scientists being able to repair injured tissues. ... > full story

Hard Work While Fatigued Affects Blood Pressure (June 27, 2008) -- When fatigued individuals perceive a task as being achievable and worth doing, they increase their effort to make up for their diminished capability due to fatigue. As a result, blood pressure tends to rise and remain elevated until the task is completed or individuals stop trying because they think success is impossible or too difficult to be justified. ... > full story

Promising Cancer Drug Target In Prostate Tumors Identified (June 27, 2008) -- Scientists report they have blocked the development of prostate tumors in cancer-prone mice by knocking out a molecular unit they describe as a "powerhouse" that drives runaway cell growth. The researchers say the growth-stimulating molecule called p110beta -- part of a cellular signaling network disrupted in several common cancers -- is a promising target for novel cancer therapies designed to shut it down. ... > full story

How Effective Are Underage Drinking Prevention Programs? (June 27, 2008) -- Underage drinking is a national concern that led the US surgeon general to issue a "Call to Action to Prevent and Reduce Underage Drinking" last year.

Portable Device Effective In Zapping Away Migraine Pain (June 27, 2008) -- A novel electronic device designed to "zap" away migraine pain before it starts has proven to be the next form of relief for those suffering from the debilitating disease, according to a study conducted at the Ohio State University Medical Center. ... > full story

Lack Of Fragile X And Related Gene Fractures Sleep (June 27, 2008) -- Lack of both the fragile X syndrome gene and one that is related could account for sleep problems associated with the disorder, which is the common cause of inherited mental impairment. ... > full story

Online Service Lets Blind Surf The Internet From Any Computer, Anywhere (June 27, 2008) -- New software lets blind and visually impaired people surf the Internet on the go. The computer science student who created the software, called WebAnywhere, says more accessibility tools must move from desktop machines to the Web. ... > full story

Why Do People Vote? Genetic Variation In Political Participation (June 27, 2008) -- A groundbreaking new study finds that genes significantly affect variation in voter turnout, shedding new light on the reasons why people vote and participate in the political system. The researchers suggest that, contrary to decades of conventional wisdom, family upbringing may have little or no effect on children’s future participatory behavior. ... > full story

Pregnancy May Help Protect Against Bladder Cancer (June 27, 2008) -- Pregnancy seems to confer some protection against bladder cancer in mice, scientists have found. Female mice that had never become pregnant had approximately 15 times as much cancer in their bladders as their counterparts that had become pregnant, according to new findings by investigators at the University of Rochester Medical Center. Their work appears online as a rapid communication in the journal Urology. ... > full story

Drug Treatment For Marfan Syndrome Looks Promising (June 27, 2008) -- A small study in 18 patients assessing the effectiveness of the drug losartan for treating Marfan syndrome in children has yielded encouraging results. Reporting in the New England Journal of Medicine, researchers showed that losartan -- a compound used for years to treat high blood pressure -- slowed the enlargement of the aorta, the most life-threatening defect associated with Marfan syndrome. ... > full story
