In the market for a spare rat heart? Not to worry, the scientists at the University of Minnesota have managed to grow a new one, using the shell of an old one as the mould. They hollowed out an old rat heart (presumably because that's the kind of thing they do for fun) and then took heart cells from another rat and 'seeded' them in the hollow one. Within four days, the cells had formed enough for scientists to be able to see the pumping action of the new heart, which is pretty incredible, if you think about it.
We're just 97 steps from being able to grow the Tin Man a heart, people.
