New research has identified correlations between weather conditions and the occurrence of West Nile virus disease in the United States, raising the possibility of being able to better predict outbreaks. The study, by researchers with the National Center for Atmospheric Research and the Centers for Disease Control and Prevention, finds strong correlations across much of the country between an increased occurrence of West Nile virus disease and above average temperatures in the preceding year. The scientists also find that precipitation influences subsequent disease outbreaks, although the impacts vary by region.
R, the free open-source software environment for statistical computing and graphics, brings out a crowd. In fact, so much so that a recent online and in-person tutorial on the subject broke training participation records for the event's organizers—the National Institute for Computational Sciences, the Extreme Science and Engineering Discovery Environment and the National Institute for Mathematical and Biological Synthesis. Approximately 800 people worldwide signed up for the four-hour, online and in-person tutorial on “Using R for HPC.” More than 420 logged in to watch online, and thirty of the participants were on site at the venue for the event.
