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.

May 13, 2011  The American Physical Society has announced that it will continue its support for the MathJax project for another year. APS was one of first organizations to become a MathJax Supporter, and is now one of the first to renew. The announcement represents an important milestone for MathJax, since support of organizations like APS over time is key to ensuring the project’s long-term success.

March 7, 2011 NPR's Weekend Edition aired a story on a recent Letter, P. Beiersdorfer, D. Layne, and E. W. Magee, Viscoelastic Suppression of Gravity-Driven Counterflow Instability, Phys. Rev. Lett. 106, 058301 (2011); see also the Viewpoint in Physics. 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. Significant hurdles would need to be overcome to make this work in practice.

In the limit where the bending modulus vanishes, we construct layer configurations with arbitrary dislocation textures by exploiting a connection between uniformly spaced layers in two dimensions and developable surfaces in three dimensions. We then show how these focal textures can be used to const...
