I'm a fan of the Johns Hopkins Applied Physics Laboratory, because they have a ton of great work going on there. Here is an awesome story from the Business Monthly about a recent, $34.5 million award that APL has received from the Department of Defense to work on thought-controlled prosthetic limbs.
While this is clearly a defense-oriented project, it's obvious to see the tremendous potential for this sort of work in the civilian world. Imagine paraplegics and quadraplegics being able to walk. Children born without legs or arms able to have a normal life. This is freaking cool.
I know I won't get a ton of hits with this post, but whatever. You all need to read this article.
