In this episode of Science Quickly, we unpack the Environmental Protection Agency’s controversial decision to change how it calculates health benefits from regulating certain air pollutants, a move that experts warn could lead to dirtier air and worse health outcomes. And we’ve achieved a major milestone in cancer care, with five-year survival rates hitting a record high, but looming policy threats could stall progress. Plus, NASA’s first-ever medical evacuation from the International Space Station could offer lessons for future missions.
