Scientists know that the best way to make a vodka martini is to mix the ingredients with a thin wooden spoon -- it combines the ingredients effectively without raising the drink's temperature the way a metal stirrer would. So why would James Bond, the world's most sophisticated martini drinker, routinely order his cocktail “shaken, not stirred”? A trio of British medical researchers believe they have the answer: The heavy-drinking 007 most likely suffered from an alcohol-induced tremor that forced him to shake his martinis.

You know that feeling you get when you listen to a favorite part of a favorite song? Some scientists have a refreshingly unscientific word for it: They call it the "chills. " In the lab they can measure the chills, which correspond with a specific pattern of brain arousal and often are accompanied by increases in heart and breathing rates and other physical responses. Now neurologists report that this human response to music -- which has existed for thousands of years, across cultures around the world -- involves dopamine, the same chemical in the brain that is associated with the intense pleasure people get from more tangible rewards such as food or addictive drugs.

Victims of bullies suffer the psychological consequences all the way until middle age, with higher levels of depression, anxiety and suicide, new research shows. The immediate ill effects of bullying have been well documented, with experts increasingly seeing it as a form of child abuse . Influential studies from Finland have made the case that people who were bullied as kids continued to suffer as young adults - girls who were bullied grew up to attempt and commit suicide more frequently by the age of 25, for instance, and boys were more likely to develop anxiety disorders.

British researchers have determined that a little-studied chemical in the cannabis plant could lead to effective treatments for epilepsy, with few to no side effects. The team at Britain's University of Reading, working with GW Pharmaceuticals and Otsuka Pharmaceuticals, tested cannabidivarin, or CBDV, in rats and mice afflicted with six types of epilepsy and found it “strongly suppressed seizures” without causing the uncontrollable shaking and other side effects of existing anti-epilepsy drugs.

A significant portion of suicidal people can be identified and referred to mental health specialists in order to help prevent suicide attempts, researchers reported Tuesday. Mental health experts have focused intently on how to lower the nation's suicide rate in all age groups. However, a major obstacle to the efforts has been the lack of a scientifically validated tool to assess suicidal behavior and suicide risk. In a paper published online in the American Journal of Psychiatr y, Columbia University researchers said their tool -- the Columbia Suicide Rating Scale -- can help predict suicidal behavior and suicide attempts.

Most kids don't become addicted to playing video games, though it may seem that way to parents. But a new study identifies risk factors for "pathological," or obsessive, gamers and says that such children become more depressed and anxious the more they play. The study released Monday in the journal Pediatrics looked at more than 3,000 elementary- and middle-school children in Singapore over a two-year period. The report says in part: "Greater amounts of gaming, lower social competence, and greater impulsivity seemed to act as risk factors for becoming pathological gamers, whereas depression, anxiety, social phobias, and lower school performance seemed to act as outcomes of pathological gaming.
