(Phys.org)—Two teams of researchers working independently have come to roughly the same conclusion: Researchers that are free to move between countries produce results that are more creative and innovative than do those that stay at home. The first team led by Cassidy Sugimto of Indiana University has published a Comment piece in the journal Nature describing their study of citation rates of researchers who travel versus those who do not. The second group, made up of the two researchers Caroline Wagner with Ohio State University and Koen Joners with the European Commission’s Joint Research Centre in Brussels offer their findings regarding comparing the scientific influence of researchers by country in a Comment piece in the same journal edition.
