About the Cover


This issue of Science examines how researchers overcome the challenges they meet along their career paths. Though presented in this image as a game, meeting those challenges—going from a postdoctoral to a permanent position, for instance, or running a productive laboratory—is a serious measure of success in the scientific life. See the News section, ``Science Careers: Playing to Win,'' beginning on page 1905. [Illustration: Linda C. Owens]
