Undiscovered is a podcast from Science Friday and WNYC Studios about the left turns, missteps, and lucky breaks that make science happen. We tell the stories of the people behind the science, and the people affected by it. Listen to more episodes here. If you were given a robot and asked to break it, would you do it?
