The world’s major cities, including New York, London and Tokyo, are losing their predominant position in the production and circulation of scientific articles, according to a study carried out by the Laboratoire interdisciplinaire solidarités, sociétés, territoires (CNRS/University of Toulouse Jean Jaurès/EHESS/ENSFEA), the INCREASE Federation at the CNRS, and the Centre Marc Bloch in Berlin (CNRS/MEAE). These results are published in the October issue of the journal Scientometrics.
