The prize is awarded to the author or authors of an outstanding paper published in the Research Articles or Reports sections of Science. Each annual contest starts with the first issue of June and ends with the last issue of the following May.
An eligible paper is one that includes original research data, theory, or synthesis; is a fundamental contribution to basic knowledge or is a technical achievement of far-reaching consequence; and is a first-time publication of the author’s own work. Reference to pertinent earlier work by the author may be included to give perspective.
Throughout the year, readers of Science are invited to nominate papers appearing in the Research Articles or Reports sections. Nominations must be submitted in our online form by June 30.
