Investigative Roundup from MedPage Today highlights investigative medical news. It focuses on the question of who really runs the NIH, where some describe Director Jay Bhattacharya. Bhattacharya is the 18th director of the NIH as of 2025, confirmed by the U.S. Senate on March 25, 2025[1][4]. He was a professor of medicine, economics, and health policy at Stanford University until March 2025[1]. The article mentions Kennedy's support for contact with the CDC and toxic fumes from airplanes. Bhattacharya's first steps include cancelling subcontracts for foreign researchers as of May 1, 2025, with a requirement for direct contracts with the NIH[1]. Existing grants with foreign funding will not be extended beyond the current year[1].
