Host Sarah Crespi talks with Staff Writer Daniel Clery about the many, many theories surrounding fast radio bursts—extremely fast, intense radio signals from outside the galaxy—and a new telescope coming online that may help sort them out.

Also this week, Sarah talks with Staff Writer Jennifer Couzin-Frankel about her story on researchers’ attempts to tackle the long-term effects of pediatric cancer treatment. The survival rate for some pediatric cancers is as high as 90%, but many survivors have a host of health problems. Jennifer’s feature is part of a special section on pediatric cancer.

This week’s episode was edited by Podigy.
