The National Institutes of Health is a sprawling and complex institution that supports the work of hundreds of thousands of scientists at universities and labs across the country.Since Trump’s inauguration that work has been stymied by confusion and uncertainty – potentially delaying or even preventing important medical research. The Post’s science reporter Carolyn Johnson has been reporting on the turmoil at NIH and talks to Martine about how it could impact a generation of scientists. Today’s show was produced by Emma Talkoff and Elana Gordon. It was edited by Maggie Penman and mixed by Sam Bair. Elana Gordon contributed reporting.Subscribe to The Washington Post here.
