The volunteer community-sourced website Grant Witness is reporting new terminations of NSF grants, while Nature reports that NSF grants to a set of prominent research universities have been put on hold.

Grant Witness, "New Grant Disruptions at NSF - We Need Your Help to Report!" (May 27) "After the mass terminations of science and health grants at NSF and NIH in 2025, and then CDC and SAMHSA in early 2026, terminations of science grants have been quiet, even as the number of new grants has slowed to a trickle. This appears to be changing at the National Science Foundation. Earlier this month, we detected the first outright termination of a NSF grant since last year. In addition, NSF is starting to use new mechanisms to disrupt research programs. As reported by Berkeleyside and Nature, 18 NSF grants to researchers at UC Berkeley were “suspended” in April, based on claims of insufficient disclosure of foreign funding. Researchers claim to be baffled as they have received no foreign funding."

Nature, "Exclusive: NSF puts new research grants to top universities on hold" (May 27) "The US National Science Foundation (NSF) — a major funder of basic research — has restricted the flow of new research grants to a group of elite universities, Nature has learnt.

"Internal agency documents obtained by Nature’s news team reveal that on 9 April, the NSF’s Office of Award Management (OAM), which finalizes grants and handles their finances, put limits on new funding to Duke University in Durham, North Carolina; Harvard University in Cambridge, Massachusetts; Princeton University in New Jersey; and Yale University in New Haven, Connecticut. A note applied to these universities in an NSF database reads: “Future Awards to Organization on Hold.” Since then, little fresh funding has been made available to these institutions by the NSF."
