The Trump administration fired all 22 members of the National Science Foundation's board on Friday. The NSF distributes approximately $9 billion annually to fund major research projects across the United States. The board members, selected for their scientific expertise, oversaw the agency's operations and grant decisions. This action represents the latest setback for American science following recent policy shifts. The firings remove experienced scientists from positions that influence which research receives federal funding and how the nation's scientific priorities are shaped. The NSF supports work across disciplines including physics, biology, engineering, and computer science. Removal of the entire board disrupts institutional knowledge and decision-making processes during a period when the agency was already navigating new leadership directives. The timing raises questions about the administration's approach to federal science funding and the role of expert input in research decisions. Scientists and research institutions have expressed concern about the implications for ongoing projects and future funding.
