Can You Grow One Without Hare?

Researchers at the Wake Forest University Baptist Medical Center's Institute for Regenerative Medicine have discovered the Holy Rabbit Grail—they've managed to create artificial bunny penises. They did this by taking a small piece of rabbit penis tissue and using it to grow cells in a lab dish. Then they seeded the cells onto a scaffold made of rabbit penis cartilage, watered it, and six weeks later—voila!—they had a new, working rabbit penis. While they may not be as lucky as rabbit's feet to us humans, they're much luckier for the rabbits that donated their cartilage.
