What's been your most exciting scientific discovery / tech invention of the last 10 years?

I’ve just been reading about carbon nanotube memory http://www.engadget.com/2009/06/09/researchers-create-nanotube-memory-that-can-store-data-for-a-bil/ and controllable molecular gears http://www.sciencedaily.com/releases/2009/06/090615102036.htm and got to wondering what other amazing developments there’ve been that I might’ve missed. Ideas?
