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.

King crabs threaten Antarctic ecosystem due to warming ocean
King crabs may soon become high-level predators in Antarctic marine ecosystems where they haven't played a role in tens of millions of years, according to a new study led by Florida Institute of Technology.
Team finds weather extremes harmful to grasslands
Fluctuations in extreme weather events, such as heavy rains and droughts, are affecting ecosystems in unexpected ways—creating "winners and losers" among plant species that humans depend upon for food.
Flood risk on rise for New York City and New Jersey coast, study finds
Flood risk for New York City and the New Jersey coast has increased significantly during the last 1,000 years due to hurricanes and accompanying storm surges, according to a study by Penn State University, Rutgers University, ...
Researchers find pigment from fossils, revealing color of extinct animals
Scientists from Virginia Tech and the University of Bristol have revealed how pigment can be detected in mammal fossils, a discovery that may end the guesswork in determining the colors of extinct species.
Researchers discover key link in understanding billion-dollar pests in agriculture
Invisible to the naked eye, plant-parasitic nematodes are a huge threat to agriculture, causing billions in crop losses every year. Plant scientists at the University of Missouri and the University of Bonn in Germany have ...
Plant debris decomposition tied to manganese
The decomposition of plant debris (litter) is a fundamental process that regulates the release of nutrients for plant growth and the formation of soil organic matter in forest ecosystems.
Scientists unravel root cause of plant twists and turns
To feed the world's burgeoning population, producers must grow crops in more challenging terrain – where plant roots must cope with barriers. To that end, Cornell University physicists and Boyce Thompson Institute plant ...
Search engine for more accurate and fast recognition of metabolites
Potential applications for the machine-learning based method include anti-doping work, drug control by the Customs and crime scene investigation.
Sea slug sniffs out seaweed's chemicals, then stalks its prey
An underwater sea slug has evolved chemical foraging and defense abilities that are functionally identical to those of terrestrial insects, despite being unrelated to their land-based counterparts and living in vastly different ...
