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.
Researchers discover surprisingly wide variation across species in genetic systems that influence aging
A new Iowa State University study focusing on insulin signaling uncovered surprising genetic diversity across reptiles, birds and mammals.
Researchers find 'decoder ring' powers in micro RNA
MicroRNA can serve as a "decoder ring" for understanding complex biological processes, a team of New York University chemists has found. Their study, which appears in Proceedings of the National Academy of Sciences, points ...
Researchers solve another piece of the puzzle how forests can effect our climate
A first global scale study has estimated how forest emitted compounds affecting cloud seeds via formation of low-volatility vapours. According to the latest projections, terrestrial vegetation emits several ...
Pheromones produced by gut bacteria found to kill resistant variants of its own kind
Like Sleeping Beauty, some research lies dormant for decades, study finds
Why do some discoveries fade into obscurity while others blaze a new trail the moment they are published? More mysteriously, why do some research papers remain dormant for years and then suddenly explode ...
Bacteria cooperate to repair damaged siblings
A University of Wyoming faculty member led a research team that discovered a certain type of soil bacteria can use their social behavior of outer membrane exchange (OME) to repair damaged cells and improve ...
One simple molecule regulates sexual behavior in Drosophila
The common vinegar fly Drosophila melanogaster is a very well-studied animal. For decades, the fly has been used as a model organism in genetic research; its genome was fully sequenced in 2000. However, until ...
New clues for the long-term viability of geological carbon dioxide storage
The carbon dioxide (CO2) at the Bravo Dome gas field in New Mexico is volcanic in origin, and its emplacement began more than a million years ago, not 10 thousand years ago, as previously estimated. Averaged a ...

Laser technique for low-cost self-assembly of nanostructures
Researchers from Swinburne University of Technology and the University of Science and Technology of China have developed a low-cost technique that holds promise for a range of scientific and technological ...
Study finds evidence of non-adaptive evolution within cicadas
University of Montana Assistant Professor John McCutcheon has once again discovered something new about the complex and intriguing inner workings of the cicada insect.
Forecasting future infectious disease outbreaks
Machine learning can pinpoint rodent species that harbor diseases andgeographic hotspots vulnerable to new parasites and pathogens. So reportsa new study in the Proceedings of the National Academy of Sciences led by ...
Gender-science stereotypes persist across the world
The Netherlands had the strongest stereotypes associating science with men more than women, according to a new Northwestern University study that included data from nearly 350,000 people in 66 nations.
