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.
How community structure affects the resilience of a network
Network theory is a method for analyzing the connections between nodes in a system. One of the most compelling aspects of network theory is that discoveries related to one field, such as cellular biology, can be abstracted ...

DNA barcodes that reliably work: A game-changer for biomedical research
In the same way that barcodes on your groceries help stores know what's in your cart, DNA barcodes help biologists attach genetic labels to biological molecules to do their own tracking during research, including of how a ...
Researchers engineer bacteria to exhibit stochastic Turing patterns
How did the zebra get its stripes, or the leopard its spots? Mankind has been trying to answer such questions since our earliest recorded days, and they resonate throughout the extant mythologies and folklores of an earlier ...
Research team reverse way potassium channels work from bacteria to human
For the first time ever, researchers at the Texas Tech University Health Sciences Center (TTUHSC) have identified a specific amino acid residue that is responsible for inverting the communication between the opening of the ...
Super-resolution imaging reveals mechanism of GLUT1 clustering
Glucose is the primary source of energy and substrate for cells, and its uptake through the cell plasma membrane is largely dependent on the glucose transport (GLUT) family. GLUT1, one of the GLUT family members, is a ubiquitously ...
Better model of water under extreme conditions could aid understanding of Earth's mantle
Deep inside the Earth exist pockets of water, but the liquid there isn't like the water on the surface.
Biologists identify a genetic mechanism in the evolution of novel traits
There has long been a debate among biologists over whether the evolution of new traits requires new genes to evolve or whether they can arise simply from the recruitment of existing genetic pathways, says developmental biologist ...
Chemists design 'miniecosystems' to test drug function
Scripps Research scientists have solved a major problem in chemistry and drug development by using droplet-sized 'miniecosystems' to quickly see if a molecule can function as a potential therapeutic.
New tool using Facebook data shows worldwide gender gap
An international group of researchers, involving scientists from the Complexity Science Hub Vienna & Medical University of Vienna and Universidad Carlos III de Madrid, developed a tool to track and analyse gender inequality ...
Novel genetic method improves efficiency of enzyme
Researchers at the U.S. Department of Energy's (DOE's) National Renewable Energy Laboratory (NREL) and the University of Georgia developed a new genetic engineering technique to dramatically improve an enzyme's ability to ...
