News Staff Writer Erik Stokstad joins host Sarah Crespi to discuss possible harms from how the shipping industry is responding to air pollution regulations—instead of pumping health-harming chemicals into the air, they are now being dumped into oceans. Also this week, William Brune, professor of meteorology and atmospheric science at Pennsylvania State University, University Park, talks about flying a plane into thunderstorms and how measurements from research flights revealed the surprising amount of air-cleaning oxidants created by lightning. In a sponsored segment from the Science/AAAS Custom Publishing Office, Sean Sanders interviews Manfred Kraus, senior director and head of in vivo pharmacology oncology at Bristol Myers Squibb, about the impact of humanized mice on preclinical research. This segment is sponsored by the Jackson Laboratory. This week’s episode was produced with help from Podigy. Listen to previous podcasts. About the Science Podcast Download a transcript (PDF).
