High levels of lead detected in rice imported from certain countries Posted: 10 Apr 2013 05:18 PM PDT Rice imported from certain countries contains high levels of lead that could pose health risks, particularly for infants and children, who are especially sensitive to lead's effects, and adults of Asian heritage who consume large amounts of rice, scientists say.

Relationships: Team women versus distant men Posted: 10 Apr 2013 04:28 PM PDT Women immerse themselves in their romantic relationships, while men place their best friendships and romantic partners on an equal but distant footing.

Subconscious mental categories help brain sort through everyday experiences Posted: 10 Apr 2013 11:15 AM PDT Researchers found that the brain breaks experiences into the "events," or related groups that help us mentally organize the day's many situations, using subconscious mental categories it creates. These categories are based on how the brain considers people, objects and actions are related in terms of how they tend to — or tend not to — pop up near one another at specific times.

In sales, confidence and charisma may not seal the deal Posted: 10 Apr 2013 11:15 AM PDT Think of a stereotypical salesperson and you're likely to conjure up someone who's extraverted, gregarious, and assertive. But a new study reveals that "ambiverts," people who are neither introverted nor extraverted but who fall somewhere in between, tend to be the most effective salespeople.

One in five seniors on risky meds; more in US South Posted: 10 Apr 2013 10:13 AM PDT A study of more than six million seniors in Medicare Advantage plans in 2009 found that 21 percent received a prescription for at least one potentially harmful "high risk medication." Nearly 5 percent received at least two. Questionable prescriptions are more common in the South and among people who live in poor areas.

Alcohol use, anxiety predict Facebook use by college students Posted: 10 Apr 2013 10:13 AM PDT Anxiety and alcohol use significantly predict emotional connectedness to Facebook, a new study suggests. According to one of the researchers, alcohol use is generally viewed as normative, or socially acceptable, among college students, so increased alcohol use may cause an increase in emotional connectedness to Facebook. Researchers also found that marijuana use predicted the opposite: a lack of emotional connectedness with Facebook.

Clinging to crevices, E. coli thrive Posted: 10 Apr 2013 07:33 AM PDT New research helps to explain how waterborne bacteria can colonize rough surfaces —- even those that have been designed to resist water.

Dark lightning: Are airplane passengers exposed to radiation from intense bursts of gamma-rays from thunderclouds? Posted: 10 Apr 2013 05:27 AM PDT Scientists have known for almost a decade that thunderstorms are capable of generating brief but powerful bursts of gamma-rays called terrestrial gamma-ray flashes, or TGFs. Because they can originate near the same altitudes at which commercial aircraft routinely fly, scientists have been trying to determine whether or not terrestrial gamma ray flashes present a radiation hazard to individuals in aircraft. In the middle of the storm, radiation doses could be roughly equal to a full-body CT scan, preliminary research suggests.

Adult generations of today are less healthy than their counterparts of previous generations Posted: 10 Apr 2013 05:24 AM PDT Despite their greater life expectancy, the adults of today are less "metabolically" healthy than their counterparts of previous generations. That's the conclusion of a large cohort study which compared generational shifts in a range of well established metabolic risk factors for cardiovascular disease. Assessing the trends, the investigators concluded that "the more recently born generations are doing worse", and warn "that the prevalence of metabolic risk factors and the lifelong exposure to them have increased and probably will continue to increase."

People who normally practice sport have a better attention span than those with bad physical health Posted: 10 Apr 2013 05:21 AM PDT Good physical health is related to a better functioning of both the central nervous system (CNS) and the autonomic nervous system (ANS), according to new research.
