Cover image: Pictured is a simulated spatial distribution of disease risks, overlaid onto a base map of North America, retrieved March 11, 2011, from Google Maps. Pink and red colors indicate simulated hotspots of high disease risk clustering. The image was created using exploratory spatial analytic software services that utilize networked computers provided by the National Science Foundation TeraGrid and the Open Science Grid to support interactive and data-intensive research. In the introduction to this PNAS Special Feature, Dawn J. Wright and Shaowen Wang discuss how spatial cyberinfrastructure facilitates scientific discoveries through streamlined collaboration and computation and make predictions for its impact on the future. See the article by Wright and Wang on pages 5488–5491. Image courtesy of Shaowen Wang and Yan Liu (University of Illinois at Urbana-Champaign, Urbana, IL).
