With their powerful jaws and jagged teeth, sharks seem perfectly designed to kill. But new research has found that there is a lot more to sharks than meets the eye.
By studying their physiology, scientists are developing ways to make faster ships, better batteries and even improved moisturizers. The process of studying nature for new ideas in engineering is called "biomimicry."
Juliet Eilperin, who has written about shark-inspired technology for Slate, joins the show to discuss the latest developments in the field and the possible commercial impact on shark populations.
