What book are you taking to the beach or the field this summer? Science’s books editor Valerie Thompson and host Sarah Crespi discuss a selection of science books that will have you catching comets and swimming with the fishes.

Sarah also talks with Mira Moufarrej of Stanford University in Palo Alto, California, about her team’s work on a new blood test that analyzes RNA from maternal blood to determine the gestational age of a fetus. This new approach may also help predict the risk of preterm birth.

This week’s episode was edited by Podigy.
