SciFriday: The Dark Continent and the Chaos Dragon of Doom

A teen robotics team from Burundi disappeared in Washington, D.C. this week. Since 1998, millions have died in African wars we rarely hear about in the West. Then we talk about the asteroid Apophis, which makes a near-Earth pass in 2029 and could interfere with some satellites. We discuss territorial spirits, ancient myths of gods battling dragons, why Thor swings a hammer instead of a sword, and Derek explains that Dagon (actually spelled Dagan) is NOT a fish-god.
