Today we uncover an invisible killer hidden, for over a hundred years, by reasonable disbelief. Science journalist extraordinaire Carl Zimmer tells us the story of a centuries-long battle of ideas that came to a head, with tragic consequences, in the very recent past. His latest book, called Airborne, details a  largely forgotten history of science that never quite managed to get off the ground. Along the way, Carl helps us understand how we can fail, over and over again, to see a truth right in front of our faces. And how we finally came around thanks to scientific evidence hidden inside a song.
