Brain gain

In the last decade, international net flows of scientific authors have changed substantially. The US initially saw net inflows of scientific authors, but this has reversed course now to a small negative outflow. Meanwhile, China and the European Union are experiencing net inflows of scientific authors. In general, there has been a significant increase in the number of scientific authors from one country to another. This trend has been driven by factors such as the availability of funding, career opportunities, and the desire for collaboration with other researchers. However, this movement of scientific authors can also create challenges for both the source and destination countries, including brain drain, the loss of valuable expertise, and the need for policy responses to manage the flow of talent.
