Proximity to coal-tar-sealed pavement raises risk of cancer, study finds Posted: 28 Mar 2013 09:52 AM PDT People living near asphalt pavement sealed with coal tar have an elevated risk of cancer, according to a new study. Much of this calculated excess risk results from exposures in children, age six or younger, to polycyclic aromatic hydrocarbons from the sealant.

America: Time to shake the salt habit? Posted: 28 Mar 2013 06:17 AM PDT Medical researchers have written a review paper summarizing data linking excessive sodium intake to increased rates of hypertension, stroke and cardiovascular disease. Is it time for national policy?

What attracts people to violent movies? Posted: 28 Mar 2013 06:17 AM PDT Why are audiences attracted to bloodshed, gore and violence? A recent study found that people are more likely to watch movies with gory scenes of violence if they felt there was meaning in confronting violent aspects of real life.

Seeing happiness in ambiguous facial expressions reduces aggressive behavior Posted: 28 Mar 2013 05:05 AM PDT Encouraging young people at high-risk of criminal offending and delinquency to see happiness rather than anger in facial expressions results in a decrease in their levels of anger and aggression, according to a new study.

Multiple moves found harmful to poor young children Posted: 28 Mar 2013 05:02 AM PDT Poor children who move three or more times before age five have more behavior problems than their peers, according to a longitudinal, representative study of children born in 20 large US cities between 1998 and 2000. Children who moved three or more times exhibited more attention problems, anxiousness, and aggressiveness at age 5.

Prekindergarten program boosts children's skills Posted: 28 Mar 2013 05:02 AM PDT Boston Public Schools' prekindergarten program is substantially improving children's readiness to start kindergarten, according to a new study of more than 2,000 children enrolled there. The program uses research-based curricula and teacher coaching, is taught primarily by masters-level teachers, and is open to any child. This study suggests that efforts to increase the enrollment of underrepresented Latino children in high-quality prekindergarten programs, such as the one studied here, may be beneficial.

Marital conflict causes stress in children, may affect cognitive development Posted: 28 Mar 2013 05:02 AM PDT Marital conflict is a significant source of environmental stress for children. Witnessing such conflict may harm their stress response systems, affecting their mental and intellectual development. Research findings suggest that stress from marital conflict can hinder children's development of cognitive ability.

Teens' struggles with peers forecast long-term adult relationships Posted: 28 Mar 2013 05:02 AM PDT Teens' struggles to connect with their peers in early adolescence while not succumbing to negative peer influences predict their capacity to form strong friendships and avoid serious problems. In a longitudinal study, researchers followed 150 teens over a 10-year period to learn about the lasting effects of peer struggles in early adolescence. They found establishing social competence in early adolescence involves negotiating conflicting goals between peer acceptance and autonomy with regard to negative peer influences.

Prebiotics: Do supplements in baby formula help prevent allergies? Posted: 28 Mar 2013 04:57 AM PDT Prebiotic supplements in infant formula may help to prevent eczema, according to a systematic review. However, the review highlights a lack of high quality evidence for the effects of prebiotics in preventing allergies.

Cold cities less sustainable than warm cities, research suggests Posted: 28 Mar 2013 04:57 AM PDT Living in colder climates in the US is more energy demanding than living in warmer climates. Scientists have calculated that climate control in the coldest large metropolitan area in the country – Minneapolis – is about three-and-a-half times more energy demanding than in the warmest large metropolitan area – Miami.

Child development: Early walker or late walker of little consequence Posted: 28 Mar 2013 04:57 AM PDT On average, children take the first steps on their own at the age of 12 months. Many parents perceive this event as a decisive turning point. However, the timing is really of no consequence. Children who start walking early turn out later to be neither more intelligent nor more well-coordinated.

Only fifteen minutes of fame? Not so Posted: 28 Mar 2013 04:55 AM PDT True fame isn't fleeting, according to new research. They studied all the names mentioned in over 2,000 English-language newspapers from the U.S., Canada and the U.K. over a period of several decades. What they found was that, contrary to popular belief (and scholarly research up to now), the people who become truly famous stay famous for decades.

Higher soy intake prior to lung cancer diagnosis linked to longer survival in women Posted: 25 Mar 2013 03:38 PM PDT A new study finds that Chinese women who consumed more soy before being diagnosed with lung cancer lived longer compared with those who consumed less soy.

Urban vegetation deters crime in Philadelphia Posted: 25 Mar 2013 01:05 PM PDT A new study of Philadelphia found that abundant vegetation, when well-maintained, can deter certain types of crime -- particularly assault and robbery. The study is the first to look at the issue across an entire urban area and offers strong evidence for urban greening as part of city planning and crime prevention strategies.
