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.Recommended Reading:America’s Air Is about to Get Dirtier—And More Dangerous70 Percent of Cancer Patients Now Survive at Least Five Years, Study FindsAstronauts Evacuate the ISS after Medical IncidentNew Study Probes How Same-Sex Behaviors Evolved in Nonhuman PrimatesE-mail us at sciencequickly@sciam.com if you have any questions, comments or ideas for stories we should cover!Discover something new everyday: subscribe to Scientific American and sign up for our daily newsletter.Science Quickly is produced by Kendra Pierre-Louis, Fonda Mwangi, Sushmita Pathak and Jeff DelViscio.
