If you're only going to listen to one, listen to the Radiolab episode. The Radiolab episode is crisp and well reported, the 99% Invisible episode is muddled and rambling by comparison.

Seconded. That Radiolab episode is one of the better ones I've listen to.

Mostly because it's laid out as "But that begs yet another question...", to which the answer is equally fascinating.

Also, it was just satisfying having a story with an ending: cause, found.
