Skin's unusual response to stretching is finally explained, and the latest in a huge effort to map DNA.In this episode:01:06 Stretching skinFor decades it’s been known that stretching skin causes more skin to grow, but the reasons why have been a mystery. Now, researchers have uncovered a mechanism to explain the phenomenon.

This week, data from its third iteration has been published and we examine the highlights.
