Most research on aging has been done on model organisms with limited life spans, such as flies and worms. Host Meagan Cantwell talks to science writer Yao-Hua Law about how long-living social insects—some of which survive for up to 30 years—can provide new insights into aging.

Also in this episode, host Sarah Crespi talks with Noshir Contractor, the Jane S. & William J. White Professor of Behavioral Sciences at Northwestern University, about his AAAS session on keeping humans in harmony during long space missions and how mock missions on Earth are being applied to plans for a crewed mission to Mars.
