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.
Antarctica losing six times more ice mass annually now than 40 years ago
Antarctica experienced a sixfold increase in yearly ice mass loss between 1979 and 2017, according to a study published today in Proceedings of the National Academy of Sciences. Glaciologists from the University of California, ...

Study shows no long-term removal of Neandertal DNA from Europeans
A team of researchers at the Max Planck Institute for Evolutionary Anthropology has found evidence that suggests there has been no long-term removal of Neandertal DNA from modern Europeans. In their paper published in Proceedings ...
Honey bee parasites feed on fatty organs, not blood
Honey bee colonies around the world are at risk from a variety of threats, including pesticides, diseases, poor nutrition and habitat loss. Recent research suggests that one threat stands well above the others: a parasitic ...
Big genome found in tiny forest defoliator
The European gypsy moth (EGM) is perhaps the country's most famous invasive insect—a nonnative species accidentally introduced to North America in the 1860s when a few escaped from a breeding experiment in suburban Boston. ...
Step forward in understanding human feet
Scientists have made a step forward in understanding the evolution of human feet.
3-D culturing hepatocytes on a liver-on-a-chip device
Liver-on-a-chip cell culture devices are attractive biomimetic models in drug discovery, toxicology and tissue engineering research. To maintain specific liver cell functions on a chip in the lab, adequate cell types and ...
Cilia beat to an unexpected rhythm in male reproductive tract, study in mice reveals
Waves of undulating cilia drive several processes essential to life. They clear debris and mucus from the respiratory tract, move spinal fluid through the brain and transport embryos from the ovaries to the uterus for implantation. ...
Researchers gain control over soft-molecule synthesis
By gaining control over shape, size and composition during synthetic molecule assembly, researchers can begin to probe how these factors influence the function of soft materials. Finding these answers could help advance virology, ...
Marine bacterium sheds light on control of toxic metals
An ocean-dwelling bacterium has provided fresh insights into how cells protect themselves from the toxic effects of metal ions such as iron and copper, in research led by the University of East Anglia (UEA).
Mutations in key protein that oversees cellular functions crucial to health and survival
A new research project uses the Canadian Light Source to help researchers understand the protein responsible for regulating heartbeats. Errors in this crucial protein's structure can lead to potentially deadly arrhythmias, ...
