The number of European researchers who leave Europe for greener pastures abroad has continued to make headlines on a regular basis in recent months. Time magazine, for example, reported in January that some 400,000 European science and technology graduates now live in the United States, and the European Commission says that only 13% of European science professionals working abroad intend to return home. More recent studies from Germany question whether the picture is as gloomy as these numbers suggest, but there's no question that legislators and funders of science in the European Union are spending a lot of time worrying about brain drain.
