Proceedings of the National Academy of Sciences of the United States of America (often abbreviated PNAS or PNAS USA) is a peer-reviewed multidisciplinary scientific journal. It is the official journal of the National Academy of Sciences, published since 1915, and publishes original research, scientific reviews, commentaries, and letters. According to Journal Citation Reports, the journal has a 2017 impact factor of 9.504. PNAS is the second most cited scientific journal, with more than 1.9 million cumulative citations from 2008-2018. In the lay press, PNAS has been described variously as "prestigious", "sedate", "renowned", and "high impact".
PNAS is a delayed open access journal, with an embargo period of 6 months that can be bypassed for an author fee (hybrid open access). Since September 2017, open access articles are published under a Creative Commons license. Since January 2019, PNAS is online-only, although print issues are available on-demand.

PNAS was established by the National Academy of Sciences (NAS) in 1914,[nt 1]:30 with its first issue published in 1915. The NAS itself had been founded in 1863 as a private institution, but chartered by the United States Congress, with the goal to "investigate, examine, experiment, and report upon any subject of science or art".
Prior to the inception of PNAS, the National Academy of Sciences published three volumes of organizational transactions, consisting mostly of minutes of meetings and annual reports. For much of the journal's history, PNAS published brief first announcements of Academy members' and associates' contributions to research. In December 1995, PNAS opened submissions to all authors without first needing to be sponsored by an NAS member.
Members were allowed to communicate up to 2 papers from non-members to PNAS every year. The review process for these papers was anonymous in that the identities of the referees were not revealed to the authors. Referees were selected by the NAS member. PNAS eliminated communicated submissions through NAS members as of July 1, 2010, while continuing to make the final decision on all PNAS papers.
In 2003, PNAS issued an editorial stating its policy on publication of sensitive material in the life sciences. PNAS stated that it would "continue to monitor submitted papers for material that may be deemed inappropriate and that could, if published, compromise the public welfare." This statement was in keeping with the efforts of several other journals. In 2005 PNAS published an article titled "Analyzing a bioterror attack on the food supply: The case of botulinum toxin in milk", despite objections raised by the U.S. Department of Health and Human Services. The paper was published with a commentary by the president of the Academy at the time, Bruce Alberts, titled "Modeling attacks on the food supply".
The following people have been editors-in-chief of the journal:
The first managing editor of the journal was mathematician Edwin Bidwell Wilson.
Robert L. Sinsheimer is head of Caltech's biology division and chairman of the editorial board of Proceedings of the National Academy of Sciences.
Brefeldin A-inhibited guanine nucleotide-exchange protein 1 is a protein that in humans is encoded by the ARFGEF1 gene.ARFGEF2
Brefeldin A-inhibited guanine nucleotide-exchange protein 2 is a protein that in humans is encoded by the ARFGEF2 gene.Ceruloplasmin
Ceruloplasmin (or caeruloplasmin) is a ferroxidase enzyme that in humans is encoded by the CP gene.Ceruloplasmin is the major copper-carrying protein in the blood, and in addition plays a role in iron metabolism. It was first described in 1948. Another protein, hephaestin, is noted for its homology to ceruloplasmin, and also participates in iron and probably copper metabolism.David L. Webster
David Locke Webster (November 6, 1888 – December 17, 1976) was an American physicist and physics professor, whose early research on X-rays and Parson's magneton influenced Arthur Compton.Fatty acid synthase
Fatty acid synthase (FAS) is an enzyme that in humans is encoded by the FASN gene.Fatty acid synthase is a multi-enzyme protein that catalyzes fatty acid synthesis. It is not a single enzyme but a whole enzymatic system composed of two identical 272 kDa multifunctional polypeptides, in which substrates are handed from one functional domain to the next.Its main function is to catalyze the synthesis of palmitate (C16:0, a long-chain saturated fatty acid) from acetyl-CoA and malonyl-CoA, in the presence of NADPH.GANC
Neutral alpha-glucosidase C is an enzyme that in humans is encoded by the GANC gene.GNA13
Guanine nucleotide-binding protein subunit alpha-13 is a protein that in humans is encoded by the GNA13 gene.GNAI1
Guanine nucleotide-binding protein G(i), alpha-1 subunit is a protein that in humans is encoded by the GNAI1 gene.GNAI3
Guanine nucleotide-binding protein G(k) subunit alpha is a protein that in humans is encoded by the GNAI3 gene.Genetic code
The genetic code is the set of rules used by living cells to translate information encoded within genetic material (DNA or mRNA sequences) into proteins. Translation is accomplished by the ribosome, which links amino acids in an order specified by messenger RNA (mRNA), using transfer RNA (tRNA) molecules to carry amino acids and to read the mRNA three nucleotides at a time. The genetic code is highly similar among all organisms and can be expressed in a simple table with 64 entries.The code defines how sequences of nucleotide triplets, called codons, specify which amino acid will be added next during protein synthesis. With some exceptions, a three-nucleotide codon in a nucleic acid sequence specifies a single amino acid. The vast majority of genes are encoded with a single scheme (see the RNA codon table). That scheme is often referred to as the canonical or standard genetic code, or simply the genetic code, though variant codes (such as in human mitochondria) exist.
While the "genetic code" determines a protein's amino acid sequence, other genomic regions determine when and where these proteins are produced according to various "gene regulatory codes".Interleukin-1 family
The Interleukin-1 family (IL-1 family) is a group of 11 cytokines that plays a central role in the regulation of immune and inflammatory responses to infections or sterile insults.Jared Diamond bibliography
Jared Mason Diamond (born September 10, 1937) is an American scientist and author best known for his popular science books The Third Chimpanzee (1991), Guns, Germs, and Steel (1997), Collapse: How Societies Choose to Fail or Succeed (2005) and The World Until Yesterday (2012). Originally trained in physiology, Diamond's work is known for drawing from a variety of fields, and he is currently Professor of Geography at the University of California, Los Angeles. The Jared Diamond bibliography includes both his scientific and popular works.
As of 2012, the Microsoft Academic Search database lists 538 publications with Diamond as an author, including collaborations with 343 co-authors.MKL1
MKL/megakaryoblastic leukemia 1 (also termed MRTFA/myocardin related transcription factor A) is a protein that in humans is encoded by the MKL1 gene.Martin Julian Buerger
Martin Julian Buerger (April 8, 1903 – February 26, 1986) was an American crystallographer. He was a Professor of Mineralogy at the Massachusetts Institute of Technology. He invented the X-ray precession camera for studies in crystallography. Buerger authored twelve textbooks/monographs and over 200 technical articles. He was awarded the Arthur L. Day Medal by the Geological Society of America in 1951. The mineral fluor-buergerite was named for him. The MJ Buerger Award (established by the American Crystallographic Association) was established in his honor.
Buerger was a member of the Provisional International Crystallographic Committee chaired by P. P. Ewald from 1946 to 1948, and he continued as a member of the IUCr Executive Committee from 1948 to 1951. He was also a member of the Commission on International Tables from its establishment in 1948 until 1981.
He was the great-grandson of Ernst Moritz Buerger, who led a group of Lutheran immigrants from Germany to the United States in 1838, and helped found what is now the Lutheran Church–Missouri Synod.In 1956, Buerger was the third person (after John C. Slater and Francis O. Schmitt) to have been appointed Institute Professor at MIT.NCOA4
Nuclear receptor coactivator 4 is a protein that in humans is encoded by the NCOA4 gene. It plays an important role in ferritinophagy, acting as a cargo receptor, binding to the ferritin heavy chain and latching on to ATG8 on the surface of the autophagosome.Olfactory receptor
Olfactory receptors (ORs), also known as odorant receptors, are expressed in the cell membranes of olfactory receptor neurons and are responsible for the detection of odorants (i.e., compounds that have an odor) which give rise to the sense of smell. Activated olfactory receptors trigger nerve impulses which transmit information about odor to the brain. These receptors are members of the class A rhodopsin-like family of G protein-coupled receptors (GPCRs). The olfactory receptors form a multigene family consisting of around 800 genes in humans and 1400 genes in mice.Proceedings
In academia and librarianship, proceedings are the acts and happenings of an academic field, a learned society, or an academic conference. For example, the title of the Acta Crystallographica journals is New Latin for "Proceedings in Crystallography"; the Proceedings of the National Academy of Sciences of the United States of America is the main journal of that academy; and conference proceedings are a collection of academic papers published in the context of an academic conference or workshop. Conference proceedings typically contain the contributions made by researchers at the conference. They are the written record of the work that is presented to fellow researchers. In many fields, they are published as supplements to academic journals; in others they may be considered grey literature. They are usually distributed in printed or electronic volumes, either before the conference opens or after it has closed. Scientific journals whose ISO 4 title abbreviations start with Proc, Acta, or Trans are journals of the proceedings (transactions) of a field or of an organization concerned with it.Ubiquitin D
Ubiquitin D is a protein that in humans is encoded by the UBD gene.Younger Dryas impact hypothesis
The Younger Dryas impact hypothesis or Clovis comet hypothesis originally proposed that a large air burst or earth impact of one or more comets initiated the Younger Dryas cold period about 12,900 BP calibrated (10,900 14C uncalibrated) years ago. The hypothesis has been contested by research as recently as 2017, arguing that most of the conclusions cannot be repeated by other scientists, and criticized because of misinterpretation of data and previous lack of confirmatory evidence.The current impact hypothesis states that the air burst(s) or impact(s) of a swarm of carbonaceous chondrites or comet fragments set areas of the North American continent on fire, causing the extinction of most of the megafauna in North America and the demise of the North American Clovis culture after the last glacial period. The Younger Dryas ice age lasted for about 1,200 years before the climate warmed again. The Hiawatha Glacier impact crater in Greenland is offered as evidence for the Younger Dryas impact hypothesis, due to its location and the speculative possibility that could be simultaneous with the start of the Younger Dryas cold period and megafauna extinctions which occurred approximately around the same era.
