Think about the size of a lady bug. Now, think 1,000 times smaller than that, and we’re talking about the size of a red blood cell. Go another 1,000 times smaller, and that’s how big a nanometer is. What can you do with something that small? We’ll find out this hour on Focus.

Guest: Robin Frewell Wilson.

Is this powerful emerging technology developing in a regulatory vacuum? Today on Focus, we're joined by law professor Robin Wilson to explore how society thinks about technologies that are still developing.
