Fans of science and radio rejoice: The Field Trip is a new podcast series dedicated to bringing you your science fix in smart and entertaining little audio packages, each one the perfect length for a commute, treadmill session, or getting-ready-for-work time.Â
The Field Trip crew has graciously allowed us to share their second episode with Mother Jones readers. The topic: fish. “To discover why so many of them seem to be disappearing from the world’s seas,” writes the crew, “we talk with Captain Mike Hudson, a commercial salmon fisherman, and Dr. Luiz Rocha at the California Academy of Sciences.” Have a listen. (And once you’re done with that, listen to the first episode here. The topic of that one is Mars, and you won’t want to miss the explanation of why showering in space is really very dangerous.)
