Changing gut bacteria through diet affects brain function Posted: 28 May 2013 03:09 PM PDT Researchers now have the first evidence that bacteria ingested in food can affect brain function in humans. In an early proof-of-concept study of healthy women, they found that women who regularly consumed beneficial bacteria known as probiotics through yogurt showed altered brain function, both while in a resting state and in response to an emotion-recognition task.

Women donate less to charity than men in some contexts Posted: 28 May 2013 01:09 PM PDT Given the chance, women are more likely than men to dodge an opportunity to donate to charity, a group of economists has found.

Picking up a second language is predicted by ability to learn patterns Posted: 28 May 2013 11:38 AM PDT Some people seem to pick up a second language with relative ease, while others have a much more difficult time. Now, a new study suggests that learning to understand and read a second language may be driven, at least in part, by our ability to pick up on statistical regularities.

Increasing problem of prescription drug abuse among youth Posted: 28 May 2013 11:37 AM PDT Young people are increasingly turning to prescription drugs to get high. Research sheds new light on what could increase or lower that risk.

For pundits, it's better to be confident than correct Posted: 28 May 2013 11:37 AM PDT Two economics graduate students have demonstrated that it simply doesn't pay as much for a pundit to be accurate as it does to be confident. It's one thing to be a good pundit, but another to be popular.

Children of long-lived parents less likely to get cancer Posted: 28 May 2013 09:25 AM PDT The offspring of parents who live to a ripe old age are more likely to live longer themselves, and less prone to cancer and other common diseases associated with aging, a study has revealed.

Soda and illegal drugs cause similar damage to teeth: Acids erode enamel Posted: 28 May 2013 09:25 AM PDT Addicted to soda? You may be shocked to learn that drinking large quantities of your favorite carbonated soda could be as damaging to your teeth as methamphetamine and crack cocaine use. The consumption of illegal drugs and abusive intake of soda can cause similar damage to your mouth through the process of tooth erosion, according to a case study.

Men, women lie about sex to match gender expectations Posted: 28 May 2013 09:23 AM PDT People will lie about their sexual behavior to match cultural expectations about how men or women should act – even though they wouldn't distort other gender-related behaviors, new research suggests.

White Mountains hikers often underprepared Posted: 28 May 2013 07:01 AM PDT In a new study based on surveys of hikers in New Hampshire's White Mountain National Forest, researchers find that many people hit the trails without essential equipment, often because they don't think it's needed for short hikes. Young, inexperienced hikers were most likely to lack essential gear.

Art appreciation is measureable Posted: 28 May 2013 06:21 AM PDT Is it your own innate taste or what you have been taught that decides if you like a work of art? Both, according to new research.

Preventive dentist visits may not help save on kids' teeth costs Posted: 27 May 2013 07:03 AM PDT It seems logical that a preventive check-up will deter cavities and other costly dental problems in children, but new research shows otherwise.
