GWEN IFILL:

This week, we're looking at innovative thinkers you may not have heard of who are using advances in technology and science to chart important new paths. That includes an effort to create a kind of a bionic brain, a new way of building an eco-friendly battery made partially out of saltwater, and a choreographer attracting new ballet lovers via YouTube.

Carlos Watson is the founder and CEO of OZY, which has stories about all of this on its site. And he joins me now.

All the tech all the time, Carlos.
