About PNAS
PNAS is one of the world's most-cited and comprehensive multidisciplinary scientific journals, publishing more than 3,300 research papers annually.
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.
PNAS is available by subscription, and all content is free after 6 months. Authors who choose the open access option can have their articles made available without cost to the reader immediately upon publication. Developing countries have free access to PNAS. Source

Significance Economic inequality continues to widen in the United States and globally, yet the organizational processes that reproduce social stratification remain insufficiently understood. This research identifies negotiation propensity as a key behavioral pathway that exacerbates class disparities: lower-class individuals are less likely to initiate negotiations, a pattern associated with persistent inequalities in pay and advancement.
Christopher A. Sims (1942–2026): Paradigm-shifting macroeconomist and econometrician
Abstract Christopher A. Sims, who died on March 14, 2026, left behind an indelible mark on macroeconomics and econometrics. His Nobel Prize winning research reshaped the paradigm for empirical macroeconomics, creating a rigorous and flexible framework for inferring the effects of macroeconomic policies. He also made important contributions to time series forecasting, Bayesian econometrics, factor modeling, approximation theory, and models of monetary and fiscal policy.

ANTHROPOLOGY Columbella rustica shell associated with Neanderthal remains. Late Pleistocene cultural continuity in the Levant The Levant served as a corridor for modern humans dispersing out of Africa during the Middle to Late Pleistocene Epoch. Interactions between modern human and Neanderthal populations in the Levant are not well-documented in the archaeological record. İsmail Baykara et al.
