Twenty percent of scientific-community respondents to a new Nature survey admitted to using neuroenhancers like Ritalin and Provigil. The poll comes on the heels of a pair of reports this winter that "brain steroids" run rampant among scientists.

Whether this is true or not, it merely takes sauntering around a university library during finals week—where there are no doubt plenty of scientists-in-training—to recognize that at least college students are willing to dabble in brain-boosting enhancements when critical evaluations are on the line.
