Major government research lab appears to be squeezing out foreign scientists

The National Institute of Standards and Technology (NIST), a top US government research lab, is reportedly taking steps that could limit the ability of foreign-born researchers to conduct work at the agency. This shift has raised concerns among lawmakers and sources, who fear it could cost the country valuable expertise and damage NIST's credibility. The proposed changes are reportedly aimed at protecting US science from theft and abuse, but the details and rationale behind the new security protocols have yet to be widely communicated.
