Most people who take up cigarette smoking, and place themselves at greater risk of cancer and lung ailments, start when they are young. A new RAND Corporation analysis finds the answer may be as simple as hiding them.

The scholars created a laboratory replica of a convenience store to examine whether limiting displays of cigarettes in retail outlets can reduce the intention of young people to begin smoking. Researchers found an 11 percent reduction in cigarette smoking susceptibility when the tobacco 'power wall' was hidden compared to when the display of tobacco products was visible behind the cashier.  

Sex will make for a happy couple, according to social psychologists, and you don't even need to do it all that often.

A popular Buddhist meditation technique that's intended to create feelings of kindness can also reduce prejudice, according to a new psychology paper.

The work in Motivation and Emotion says that just seven minutes of Loving-kindness meditation (LKM), a Buddhist practice that promotes unconditional kindness towards oneself and others, is effective at reducing racial bias. Look for that to be on The Dr. Oz Show real soon.

If you're a man, how much you eat may have more to do with the gender of your dining companions than your appetite, according to a paper published in Evolutionary Psychological Science which claims that men will eat significantly more food in the company of women than they will with other men. 

A team of scholars recently looked at what emotional effects - if any - eating different yogurts had on people.

Their article in Food Research International claims that being pleasantly surprised or disappointed with a food product can actually change a person's mood, at least based on emotional responses. Eating vanilla yogurt made people feel happy, and that yogurt with lower fat content gave people a stronger positive emotional response. Yogurt with different fruits did not show much difference in their emotional effect.

Some people throw salt over their shoulder, some wear a particular shirt when their favorite sports team is playing, while some believe food grown using one process rather than another will mean better nutrition.  

Even smart, educated, emotionally stable people engage in superstitions that they recognize are unreasonable. 

A new paper proposes an entirely new approach to risk assessment for future violence. Previous approaches have relied on looking at risk factors that happen to be linked to, but may not cause, violence, for example, being young, male, of lower social class, with previous violent convictions.

The new approach is instead based on identifying risk factors that have a clear causal link to violence, and include symptoms of major mental disorder, the patient's living condition, and whether they are taking medication.

Placebo-controlled trials are the recognized standard for demonstrating the efficacy of clinical and pharmacological treatments so it is significant to proponents of mindfulness meditation that it reduced pain more effectively than placebo.

The paper Journal of Neuroscience says that study participants who practiced mindfulness meditation reported greater pain relief than placebo. The study used a two-pronged approach - pain ratings and brain imaging - to determine whether mindfulness meditation is merely a placebo effect. Seventy-five healthy, pain-free participants were randomly assigned to one of four groups: mindfulness meditation, placebo meditation ("sham" meditation), placebo analgesic cream (petroleum jelly) or control.

Scientist who specialize in sex and sexuality tested a sample of men using a device that measures the reaction of a mans privates to various visual stimuli.   Men who are attracted to transgender women were not turned on by porn featuring two gay men, but they were turned on by porn featuring women only, and three kinds of “shemale” porn (“Man on Shemale”, “Shemale on Female”, and “Shemale on Shemale”).   So a man who likes transgender women (people born essentially biologically male who are sociologically more like women) does not have to be “at least” bisexual, or really gay but hiding it, or any such thing.   What studies like this hi-lite is the sparse vocabulary most of us have in the USA.  Word

By Kate Gammon, Inside Science --Without risky ideas in science, the world wouldn't have new cancer treatments, an understanding of dark matter – or even the World Wide Web. But as scientific disciplines mature, scientists in them choose to go for small, incremental advances rather than risky leaps – and those choices lead to a system that's slower and more expensive than it needs to be, according to the study authors.

The problem?
