This week we hear stories on animal hoarding, how different languages have different numbers of colors, and how to tell a wakeful jellyfish from a sleeping one with Online News Editor Catherine Matacic, Brice Russ, and Sarah Crespi.  

Andrew Wagner talks to Karl-Heinz Kampert about a long-term study of the cosmic rays blasting our planet. After analyzing 30,000 high-energy rays, it turns out some are coming from outside the Milky Way.
