Hooray for science!

This is far too awesome:

A team of scientists has grown human bladder sacs in the laboratory and successfully transplanted them into people.

They are hoping that they can grow other organs as well like kidneys, livers and hearts. This will heavily reduce the requirements for donors and with some luck may even make organ transplants much cheaper. What's best about this is unlike a transplant, where you're never really going to have an identical tissue match and so the chance of rejection is always there, these are made from the patients own cells. This is really great technology and I hope it starts to see wide use.
