Performance-Enhancing Brain Power

Scientists Take Drugs to Boost Brain Power
Twenty percent of scientists admit to using performance-enhancing prescription drugs for non-medical reasons, according to a survey released Wednesday by Nature, Britain's top science journal. The overwhelming majority of these med-taking brainiacs said they indulged in order to "improve concentration," and 60 percent said they did so on a daily or weekly basis. The 1,427 respondents -- most of them in the United States -- completed an informal, online survey posted on the "Nature Network" Web forum, a discussion site for scientists operated by the Nature Publishing Group.
