What Does an Ant's Organs Look Like?

We’re learning about the wild world of ants, and a new research project documenting the morphology of over 2,000 ant specimens. Helping us along is Evan Economo, a researcher with the University of Maryland. And more animal news, there's new research into how horses make their “whinny” sound, and it turns out they’re creating two different tones simultaneously. We’ll get insights from Élodie Briefer with the University of Copenhagen.Plus, Edgar talks with Peter Girguis, a Harvard Professor of Organic and Evolutionary Biology, about his work curating an exhibit at the Harvard Museum of Natural History titled "Sea Monsters: Wonders of Nature and Imagination.”
