FASTER, PLEASE: Grow your own blood vessels. “Using your own stem cells—extracted from your fat or bone marrow—a San Diego company called Organovo is offering a $200,000 bioprinter that prints human tissue in 3D. While the current model, which ships this year, can only handle simple stuff like blood vessels, printing up whole organs is very close.”

From the comments: “In other news, Lexmark will release a home version for $175.00. Unfortunately the four DNA component cartridges will be $11,000 apiece, and only let you print something about the size of a tonsil before needing to be replaced.”
