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.

Harnessing an innate protection against Ebola
In their evolutionary battle for survival, viruses have developed strategies to spark and perpetuate infection. Once inside a host cell, the Ebola virus, for example, hijacks molecular pathways to replicate itself and eventually ...

Decades-old crustaceans coaxed from lake mud give up genetic secrets revealing evolution in action
Human actions are changing the environment at an unprecedented rate. Plant and animal populations must try to keep up with these human-accelerated changes, often by trying to rapidly evolve tolerance to changing conditions.

Researchers find the key to reducing drag on superhydrophobic surfaces can come down to a single parameter
Sometimes, the most complex problems can be solved with the simplest approaches. Such was the case for researchers at UC Santa Barbara as they tried to resolve a longstanding issue of fluid friction—the resistance between ...

Genetic engineering sheds light on ancient evolutionary questions
Cyanobacteria are single-celled organisms that derive energy from light, using photosynthesis to convert atmospheric carbon dioxide (CO2) and liquid water (H2O) into breathable oxygen and the carbon-based molecules like proteins ...

Researchers find deer carry SARS-CoV-2 variants that are extinct in humans
Cornell University researchers have found that white-tailed deer—the most abundant large mammal in North America—are harboring SARS-CoV-2 variants that were once widely circulated, but no longer found in humans.

With rapidly increasing heat and drought, can plants adapt?
At a time when climate change is making many areas of the planet hotter and drier, it's sobering to think that deserts are relatively new biomes that have grown considerably over the past 30 million years. Widespread arid ...
