Widespread exposure to BPA substitute is occurring from cash register receipts, other paper Posted: 11 Jul 2012 06:02 PM PDT People are being exposed to higher levels of the substitute for BPA in cash register thermal paper receipts and many of the other products that engendered concerns about the health effects of bisphenol A, according to a new study. Bisphenol S (BPS) is now frequently found in thermal and recycled paper and paper currency. BPS is closely related to BPA, with some of the same estrogen-mimicking effects, and unanswered questions exist about whether it is safer.

The eyes don't have it: New research into lying and eye movements Posted: 11 Jul 2012 05:59 PM PDT Widely held beliefs about Neuro-Linguistic Programming and lying are unfounded. Proponents of Neuro-Linguistic Programming (NLP) have long claimed that it is possible to tell whether a person is lying from their eye movements. New research reveals that this claim is unfounded, with the authors calling on the public and organizations to abandon this approach to lie detection.

No reliable evidence on effectiveness of electric fans in heatwaves Posted: 11 Jul 2012 09:30 AM PDT A fan might help to increase heat loss if the temperature is below 35°C and the fan is not directly aimed at the person, but, when temperatures are above 35 °C, the fan might actually contribute to heat gain.

The more gray matter you have, the more altruistic you are Posted: 11 Jul 2012 09:30 AM PDT The volume of a small brain region influences one's predisposition for altruistic behavior. Researchers have shown that people who behave more altruistically than others have more gray matter at the junction between the parietal and temporal lobe, thus showing for the first time that there is a connection between brain anatomy, brain activity and altruistic behavior.

Social responsibility: Monitoring children's social media usage is important, but so is allowing their mistakes Posted: 11 Jul 2012 08:14 AM PDT How parents can prevent cyberbullying and protect personal privacy on social media -- both through their child's social media account and their own account.

Early-life exposure to PCE, chemical in drinking water, may affect vision, study finds Posted: 11 Jul 2012 07:49 AM PDT Prenatal and early childhood exposure to the chemical solvent tetrachloroethylene found in drinking water may be associated with long-term visual impairments, particularly in the area of color discrimination, a new study has found.

Evidence supports health benefits of 'mindfulness-based practices' Posted: 11 Jul 2012 07:48 AM PDT Specific types of "mindfulness practices" including Zen meditation have demonstrated benefits for patients with certain physical and mental health problems, according to a new report.

Moderate alcohol consumption may help prevent bone loss, study suggests Posted: 11 Jul 2012 07:07 AM PDT Drinking a moderate amount of alcohol as part of a healthy lifestyle may benefit women's bone health, lowering their risk of developing osteoporosis. A new study assessed the effects of alcohol withdrawal on bone turnover in postmenopausal women who drank one or two drinks per day several times a week. Researchers measured a significant increase in blood markers of bone turnover in women after they stopped drinking for just two weeks.

Redefining what it means to be narcissistic in a social media world Posted: 11 Jul 2012 04:40 AM PDT A new study shows that Facebook users are not as narcissistic as once thought. The researchers focused on whether social networking sites like Facebook were promoting narcissism in college-aged users in a world where being constantly hunched over computers and smart phones is the norm.

Cutting daily sitting time to under three hours might extend life by two years Posted: 09 Jul 2012 08:11 PM PDT Restricting the amount of time spent seated every day to less than three hours might boost the life expectancy of U.S. adults by an extra two years, indicates a new analysis.
