Pornography reinforces sexist attitudes among a subgroup of heterosexuals Posted: 06 Sep 2013 07:25 AM PDT Pornography has long held a controversial place in society, and its relationship with a number of behaviors and attitudes has been highly debated. But the concern remains: How does viewing pornography affect our attitudes towards women? A recent article found that exposure to pornography was related to and increased sexist attitudes, but only among a subgroup of users.

First detailed view of morphing Parkinson's protein revealed Posted: 06 Sep 2013 07:25 AM PDT Researchers have taken detailed images and measurements of the morphing structure of a brain protein thought to play a role in Parkinson's disease, information that could aid the development of medications to treat the condition.

Neuroscientists show that monkeys can decide to call out or keep silent Posted: 06 Sep 2013 07:21 AM PDT "Should I say something or not?" Human beings are not alone in pondering this dilemma -- animals also face decisions when they communicate by voice. Neurobiologists have now demonstrated that nerve cells in the brain signal the targeted initiation of calls -- forming the basis of voluntary vocal expression.

Education protects women from the obesity associated with urban living Posted: 06 Sep 2013 07:13 AM PDT Research into the rise in obesity associated with the burgeoning industrial and service sectors in low- and middle-income countries found that education is a key factor in reducing the negative impact on women's health.

Static killers? Natural killer cell activity can be influenced by phosphorylating a protein in NK cells Posted: 06 Sep 2013 07:13 AM PDT Mammals contain cells whose primary function is to kill other cells in the body. The so-called Natural Killer (NK) cells are highly important in defending our bodies against viruses or even cancer. Scientists provide evidence that NK cell activity can be influenced by phosphorylating a protein (STAT1) in NK cells. The results could be of immediate therapeutic relevance.
