The Proceedings of the National Academy of Sciences of the United States of America, usually referred to as PNAS, is the official journal of the United States National Academy of Sciences (NAS). PNAS is an important scientific journal that printed its first issue in 1915 and continues to publish highly cited research reports, commentaries, reviews, perspectives, feature articles, profiles, letters to the editor, and actions of the Academy. Coverage in PNAS broadly spans the biological, physical, and social sciences. Although most of the papers published in the journal are in the biomedical sciences, PNAS recruits papers and publishes special features in the physical and social sciences and in mathematics. PNAS is published weekly in print, and daily online in PNAS Early Edition. PNAS was established by NAS in 1914, with its first issue published in 1915. The NAS itself had been founded in 1863 as a private institution, but chartered by the US Congress, with the goal to "investigate, examine, experiment, and report upon any subject of science or art." By 1914, the Academy was well established.

It is no secret that over the last few decades, humans have changed nature at an ever-increasing rate. A growing collection of research covers the many ways this is impacting our quality of life, from air quality to nutrition ...

As oceans warm, large fish struggle

Warming ocean waters could reduce the ability of fish, especially large ones, to extract the oxygen they need from their environment. Animals require oxygen to generate energy for movement, growth and reproduction. In a recent ...

European eels: One gene pool fits all

European eels spawn in the subtropical Sargasso Sea but spend most of their adult life in a range of fresh- and brackish waters, across Europe and Northern Africa. How eels adapt to such diverse environments has long puzzled ...

Land deals meant to improve food security may have hurt

Large-scale land acquisitions by foreign investors, intended to improve global food security, had little to no benefit, increasing crop production in some areas while simultaneously threatening local food security in others, ...

Volcanic microbes

Oak Ridge National Laboratory contributed to an international study that found almost 300 novel types of microbes living near a deep sea volcano. These microbes, which could be used in biotechnology, reveal new insights about ...
