The American Association for the Advancement of Science (AAAS) will offer an annual prize of $5000 for the best paper published in the Reports section of Science. The first contest year began with the October 1, 1976, issue. An AAAS selection panel will make the evaluation and choose the winning paper. Plans call for awarding the prize at the annual AAAS meeting, and the recipient will be asked to present a review paper on the allied field at the annual meeting. This paper will also be published in Science.
