The Proceedings of the National Academy of Sciences (PNAS), the official journal of the National Academy of Sciences (NAS), is an authoritative source of high-impact, original research that broadly spans the biological, physical, and social sciences. The journal is global in scope and submission is open to all researchers worldwide.

PNAS was established in 1914 in honor of the semicentennial anniversary of the National Academy of Sciences. Since then, we have worked to publish only the highest quality scientific research and to make that research accessible to a broad audience. In addition, PNAS publishes science news, Commentaries, Perspectives, Colloquium Papers, podcasts, and profiles of NAS members.

In 1995, PNAS began accepting Direct Submissions from researchers without an NAS affiliation. While we retain strong ties with the NAS, whose members oversee the journal’s rigorous three-tier peer review process, we now receive more than 17,000 Direct Submissions each year. Direct Submissions account for more than 75% of the research we publish.
