I found this article on CNN's website. It didn't seem "newsy" enough for the news forum, so I thought I'd post it here. It talks about some of the possibilites of nanotechnology, such as detecting cancers, and some of the surprising discoveries scientists have made, such as that atoms make noise when they're moved. There are also some pictures, including a cool one of electrons interacting. Here's the link:

for some reason i thought it took many more than 400,000 individual atoms to pan the width of a human hair. but an interesting article nonetheless
