February 28, 2012  The editors of the APS journals have selected 149 new Outstanding Referees for 2012, out of more than 60,000 currently active referees. Initiated in 2008, the highly selective Outstanding Referee program recognizes scientists who have been exceptionally helpful in assessing manuscripts for publication in the APS journals. Selections are based on two decades of records on the number, quality, and timeliness of referee reports. The 2012 honorees come from 31 different countries, with large contingents from the US, Germany, UK, Canada, and France. The decisions were difficult and there are many excellent referees who have yet to be recognized. By means of the program, APS expresses appreciation to all referees, whose efforts in peer review not only keep the standards of the journals at a high level, but in many cases also help authors to improve the quality and readability of their articles—even those that are not published by APS. For more information and a sortable listing of all Outstanding Referees, please visit http://publish.aps.org/OutstandingReferees.

July 26, 2011  The Niels Bohr Library and Archives is pleased to announce that it has digitized the complete Samuel A. Goudsmit Papers
(1921–1979, 30 linear feet, approximately 67,000 images). The Goudsmit Papers are a major international collection of correspondence, research notebooks, reports, World War II science documents, and other material of Goudsmit, a Dutch physicist who spent most of his career in the US and was involved at the cutting-edge of physics for more than 50 years. Goudsmit became Editor of Physical Review in 1951 and was responsible for launching Physical Review Letters seven years later. In 1967 he was named APS Editor-in-Chief.

June 6, 2011 The American Physical Society is pleased to announce a refresh of all PDFs contained in the scanned portion of our Physical Review Online Archive (PROLA). APS was one of the first publishers to put our entire backfile online, completing the scanning process in May 2001. In those early days, APS opted to put our content online quickly and in an inexpensive manner that would then allow us to take advantage of any future improvements in technology. We have now completed the next step by partnering with Aquaforest. Using their Autobahn DX conversion software, we have efficiently reprocessed our entire scanned archive of approximately 250,000 articles, further compressing them and adding searchable text. Researchers will find these enhanced PDFs faster to download and much more convenient to navigate and read. APS is committed to ensuring the long-term availability and usability of all of the information that we publish. More News/Announcements

The Letter shows how adding something as simple as cornstarch can in principle suppress the turbulent flow which caused the oil-well-plugging "top kill" procedure to fail.

A simple cell model consisting of a catalytic reaction network is studied to show that cellular states are self-organized in a critical state for achieving optimal growth; we consider the catalytic network dynamics over a wide range of environmental conditions, through the spontaneous regulation of ...

The tasks of neural computation are remarkably diverse. To function optimally, neuronal networks have been hypothesized to operate near a nonequilibrium critical point. However, experimental evidence for critical dynamics has been inconclusive. Here, we show that the dynamics of cultured cortical ne... [Phys. Rev. Lett. 108, 208102 (2012)] Published Wed May 16, 2012

The behavior of liquid water under an electric field is a crucial phenomenon in science and engineering. However, its detailed description at a microscopic level is difficult to achieve experimentally. Here we report on the first ab initio molecular-dynamics study on water under an electric field. W...
