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.

Animal aggression depends on rank within social hierarchies

Humans and animals alike constantly size up one another. In the workplace, a new employee quickly learns which coworkers are the most respected—and therefore hold more power. Big brothers boss around little brothers. In ...

A COSMIC approach to nanoscale science

COSMIC, a multipurpose X-ray instrument at Lawrence Berkeley National Laboratory's (Berkeley Lab's) Advanced Light Source (ALS), has made headway in the scientific community since its launch less than 2 years ago, with groundbreaking ...

Researchers detects chiral structures using vortex light

Recently, the Laboratory of Micro and Nano Engineering, School of Engineering Science, University of Science and Technology of China (USTC) has made important progress in the field of structural chirality detection research ...

Oaks adapt drought resistance to local conditions

As climate change brings an increase in the frequency and severity of droughts, forest dieback is a key cause for concern: forests act as reservoirs of biodiversity and also allow vast amounts of carbon to be stored, reducing ...

Designing soft materials that mimic biological functions

Northwestern Engineering researchers have developed a theoretical model to design soft materials that demonstrate autonomous oscillating properties that mimic biological functions. The work could advance the design of responsive ...

Extinct atom reveals the long-kept secrets of the solar system

Using the extinct niobium-92 atom, ETH researchers have been able to date events in the early solar system with greater precision than before. The study concludes that supernova explosions must have taken place in the birth ...
