I have found a fun podcast on emergence [1]:

What happens when there is no leader? Starlings, bees, and ants manage just fine. In fact, they form staggeringly complicated societies, all without a Toscanini to conduct them into harmony. How? That?s our question this hour. We gaze down at the bottom-up logic of cities, Google, even our very own brains. Featured: author Steven Johnson, fire-flyologists John and Elizabeth Buck, biologist E.O. Wilson, Ant expert Debra Gordon, mathematician Steve Strogatz, economist James Surowiecki, and neurologists Oliver Sacks and Christof Koch.

The show also covers the wisdom of crowds and the neurological basis for consciousness (yes, you too are a multiagent system!). If you like the show, you might want to subscribe to the radiolab podcast feed. [2]
