Need a new heart?

Holy Crap.

I am flabbergasted. I watched Wired News last night and a scientist took a regular HP printer and instead of ink in the cartridges he put different types of cells (muscle, bone, etc). So guess what he did? He printed a HEART. A two chamber heart that began to beat before it was even done! Layer by layer this printer printed a heart. Wow. He also created a spray on skin for burn victims using their own skin cells, and grew a working bladder in an incubator. But my goodness... he printed an organ!

Just imagine!
