We have a lot to learn from ants. This episode digs into the hierarchy of ant colonies (spoiler alert: there is none) and why they walk in a straight line (spoiler alert: they don’t). We’ll also find out about epic ant battles and how the study of ants is teaching us about how cancer spreads, how the internet can be improved, and could even give us new ways to explore Mars. Plus: Our Moment of Um answers the question: Why do the mountains look blue from far away?
