Alcohol use disorders linked to death and disability Posted: 26 Nov 2013 12:58 PM PST Disorders related to the abuse of alcohol contribute significantly to the burden of disease in the U.S., finds a new study.

Gratitude or guilt? People spend more when they 'pay it forward' Posted: 26 Nov 2013 10:47 AM PST As shoppers across the nation prepare to pounce on Black Friday sales, researchers are looking at what happens to commerce when there's no set price tag. In an exhaustive study of consumer behavior, they found that shoppers spend more money when engaged in a chain of goodwill known as "pay-it-forward" than when they can name their own price.

High-fat diet during puberty speeds up breast cancer development Posted: 26 Nov 2013 09:39 AM PST New findings show that eating a high-fat diet beginning at puberty speeds up the development of breast cancer and may actually increase the risk of cancer similar to a type often found in younger adult women.

Gene mutation for excessive alcohol drinking found Posted: 26 Nov 2013 09:39 AM PST Researchers have discovered a gene that regulates alcohol consumption and when faulty can cause excessive drinking. They have also identified the mechanism underlying this phenomenon.

Brain reward gene influences food choices in the first years of life Posted: 26 Nov 2013 09:36 AM PST Research has suggested that a particular gene in the brain's reward system contributes to overeating and obesity in adults. This same variant has now been linked to childhood obesity and tasty food choices, particularly for girls, according to a new study.

Unhappy meals? Majority of very young children in California eat fast food at least once per week Posted: 26 Nov 2013 06:27 AM PST A surprisingly large percentage of very young children in California, including 70 percent of Latino children, eat fast food regularly, according to a new policy brief.

Electronic cigarettes: New route to smoking addiction for adolescents Posted: 26 Nov 2013 06:27 AM PST E-cigarettes have been widely promoted as a way for people to quit smoking conventional cigarettes. Now, in the first study of its kind, researchers are reporting that, at the point in time they studied, youth using e-cigarettes were more likely to be trying to quit, but also were less likely to have stopped smoking and were smoking more, not less.

Regular physical activity in later life boosts likelihood of 'healthy aging' up to sevenfold Posted: 25 Nov 2013 03:56 PM PST It's never too late to get physically active, with even those starting relatively late in life reaping significant health benefits, finds research.

Cancer patients at increased risk for severe flu complications Posted: 25 Nov 2013 02:20 PM PST Weakened immune systems due to diseases like cancer cause increased risk of severe complications from the flu virus — experts advise vaccine shot, not mist.

Study examines potential evolutionary role of 'sexual regret' in human survival, reproduction Posted: 25 Nov 2013 01:47 PM PST A study finds men regret missing opportunities to have sex, while women feel remorse for having casual, meaningless sex.

Oxytocin leads to monogamy Posted: 25 Nov 2013 01:43 PM PST How is the bond between people in love maintained? Scientists have discovered a biological mechanism that could explain the attraction between loving couples: If oxytocin is administered to men and if they are shown pictures of their partner, the bonding hormone stimulates the reward center in the brain, increasing the attractiveness of the partner, and strengthening monogamy.

Barriers to HPF vaccination among teens Posted: 25 Nov 2013 01:42 PM PST Barriers to human papillomavirus (HPV) vaccination among adolescents in the U.S. range from financial concerns and parental attitudes to social influences and concerns about the vaccination's effect on sexual behavior, according to a review of the available medical literature.

Navigational ability visible in brain Posted: 25 Nov 2013 09:14 AM PST The brains of people who immediately know their way after traveling along as a passenger are different from the brains of people who always need a GPS system or a map to get from one place to another.

Online shoppers favor white sellers in classified ads, study finds Posted: 25 Nov 2013 09:13 AM PST Online classified ad shoppers respond less often and offer lower prices when a seller is black rather than white, finds a newly published study based on a field experiment.

Video game play may provide learning, health, social benefits Posted: 25 Nov 2013 09:11 AM PST Playing video games, including violent shooter games, may boost children's learning, health and social skills, according to a review of research on the positive effects of video game play.

Controlling circadian rhythms Posted: 25 Nov 2013 09:11 AM PST Most people have experienced the effects of circadian-rhythm disruption. To have any hope of modulating our biological "clocks," we need to first understand the physiology at play. A new study helps explain some of the biophysical processes underlying regulation of circadian rhythms.

Teens eat more, cheat more after playing violent video games Posted: 25 Nov 2013 07:10 AM PST Playing violent video games not only increases aggression, it also leads to less self-control and more cheating, a new study finds.
