How Advanced is Whale Talk David Gruber and Shane Gero
Soon after whaling ships began operating in the North Pacific, an interesting trend emerged. Within just a few years, whalers saw a 58% drop in their successful strikes.

David Biello shares the surprising benefits of whale excrement.

Laura Morelli traces the history of how we assign value to the visual arts.
