Radiolab Folgen

In a cruel trick of evolution, humans can stand just three feet from a ferocious animal and still be perfectly safe. This hour, Radiolab goes to the zoo.

Jorge Luis Borges wrote, "Time is the substance from which I am made. Time is a river which carries me along, but I am the river; it is a tiger that devours me, but I am the tiger; it is a fire that consumes me, but I am the fire." And it’s still as close a definition as we have. This hour of Radiolab, we try our hand at unlocking the mysteries of time. We stretch and bend it, wrestle with its subjective nature, and wrap our minds around strategies to standardize it...stopping along the way at a 19th-century railroad station in Ohio, a track meet, and a Beethoven concert.

Birds do it, bees do it...yet science still can't answer the basic question: why do we sleep?
