Research gets increasingly international Big US report documents increases in international collaboration and Chinese science output.

China’s share of global science and engineering publications has pulled within a percentage point of those from the United States, according to the latest research statistics published by the US National Science Foundation (NSF). The agency's report, released on 19 January, also underscores the rising importance of international scientific collaboration. Between 2000 and 2013, the percentage of publications with authors from multiple countries rose from 13.2% to 19.2%. Interestingly "The 2016 Indicators report changed the metrics by which it measures publications. Instead of using the Thomson Reuters Science Citation Index and the Social Science Citation Index, the NSF went with Elsevier’s Scopus database. The change was made to try to get a more accurate view of global trends, says Carol Robbins, the NSF senior analyst who oversaw the bibliometrics portion of the report. By using Scopus, the 2016 analysis was able to look at roughly 17,000 journals, compared to the 5,087 included in the previous report two years ago."
