The National Institutes of Health is capping an important kind of funding for medical research at universities, medical schools, research hospitals and other scientific institutions.

In the latest step by the Trump administration affecting scientific research, the NIH says the agency is limiting funding for “indirect costs” to 15 percent of grants. That’s far below what many institutions have been getting to maintain buildings and equipment and pay support staff and other overhead expenses. For example, Harvard receives 68 percent and Yale gets 67 percent, according to the NIH.
