Proceedings of the National Academy of Sciences of the United States of America

PNAS has been at the forefront of scientific research for over a century. Established in 1914 as the peer reviewed journal of the National Academy of Sciences (NAS), PNAS is now one of the largest and most-cited multidisciplinary scientific journals in the world, with a global readership and more than 3,500 research articles published annually.
PNAS publishes exceptional research in all branches of the Biological, Physical, and Social Sciences. Innovation often happens at the margins, and we are particularly interested in research that crosses disciplinary bounds, answers questions with broad scientific impact, or breaks new ground. Direct Submissions account for more than 75% of the research PNAS publishes.
