Where science meets war: Kit Parker's lab

This week on 60 Minutes, Lesley Stahl and producer Andrew Metz reported on how the U.S. military's counterinsurgency tactics are being adapted by local law enforcement for gang-ridden American cities. Their story also introduced us to the memorable Major Kit Parker, a Harvard bioengineering professor who served two combat tours in Afghanistan.

In this 60 Minutes Overtime feature, you'll follow Major Parker back to his Harvard lab, where he and his team are devising a number of innovative -- even bizarre -- new solutions to age-old problems of the battlefield. For example, in the above video, you'll learn how Kit's lab is studying cuttlefish skin cells to design better camouflage and how they've used the cotton candy machine to help build a better wound dressing. And that's just the beginning.
