The massive changes in US research brought about by the new administration of President Donald Trump are causing many scientists in the country to rethink their lives and careers. More than 1,200 scientists who responded to a Nature poll — three-quarters of the total respondents — are considering leaving the United States following the disruptions prompted by Trump. Europe and Canada were among the top choices for relocation.

The trend was particularly pronounced among early-career researchers. Of the 690 postgraduate researchers who responded, 548 were considering leaving; 255 of 340 PhD students said the same.
