The National Science Foundation (NSF), a primary source of funding for basic research in science, mathematics, and engineering at U.S. academic institutions, is facing significant uncertainty following a preliminary federal budget proposal that aims to reduce its funding by more than half — approximately $4.7 billion.
On the same day the proposal was released, the NSF announced it had canceled 344 previously approved grants, citing a realignment with current agency priorities. These cancellations follow two earlier rounds in April that rescinded more than a thousand awards. Additionally, recent reports indicate that the agency has halted the issuance of new awards and paused funding for ongoing projects. The NSF declined to comment when asked about these developments.
Amid these events, NSF Director Sethuraman Panchanathan resigned unexpectedly, stating he believed he had done all he could in his role. Members of the scientific community have expressed concern over the potential effects of such budget reductions, particularly for researchers, students, and early-career scientists who rely on this support.
Some of the canceled grants were associated with studies on misinformation, educational inclusion, and initiatives aimed at supporting students from underrepresented backgrounds. Reports also highlight the cancellation of scientific conferences and academic gatherings that provided important professional opportunities, especially for students from less privileged backgrounds.
Although the budget process will require Congressional review and may take several months, the ongoing uncertainty has caused widespread concern among scientists, some of whom are beginning to explore the possibility of continuing their research abroad.
