Medical technology has come a long way. Check out this Medical Technology video on engineering and growing organs. Anthony Atala's state-of-the-art lab grows human organs -- from muscles to blood vessels to bladders, and more. At TEDMED, he shows footage of his bio-engineers working with some of its sci-fi gizmos, including an oven-like bioreactor (preheat to 98.6 F) and a machine that "prints" human tissue.

The most exciting/interesting part is at 11:00. Where they discussing using printer technology to "print" organs. Layer, after layer, after layer.

Absolutely amazing!
