Birds do it, bees do it - but science still can't answer the basic question: why do we sleep? Every creature on the planet sleeps, from giant humpback whales to tiny fruit flies.

Radiolab takes a peek at iguanas sleeping with one eye open, gets in bed with a pair of sleep-deprived new parents and eavesdrops on the uneasy dreams of rats.
