About Focus
Physical Review Focus is a free service of the American Physical Society (APS). Focus stories explain selected physics research published in the APS journals Physical Review (PR) and Physical Review Letters (PRL). The Focus site also provides an archive of links to Physics News Update stories from the American Institute of Physics that cover papers from APS journals.

Selection Criteria
Since the main goal of the service is to communicate current research beyond the bounds of a physics sub-discipline, the selection criteria for Focus differ from those of a research journal. Papers will often be chosen based on educational value and intrinsic interest to non-specialists, rather than simply on scientific merit. Research that is well-covered by other sources may also be passed over in favor of less-publicized work.

Journal Articles
Our links to APS journal articles use the simple "link manager" formula (details) and take readers to the free abstract page of the paper. Subscribers to the online journals can access the full text from there (subscription information). Journalists can obtain free copies of the papers from Physics News Select Articles (write to physnews@aip.org to get a username and password) or from the Focus Editor.

Copyrights
Focus stories may only be reprinted with permission from the American Physical Society (write to assocpub@aps.org). Image copyrights are owned by those named in the image credits. Images may not be displayed elsewhere on the Web or otherwise reproduced without permission of the copyright owners.
