EPA weakens air pollution rules, cancer survival soars, and NASA evacuates astronauts

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.
