For the first time, scientists have managed to grow an arm in a lab. This rat forelimb seems to be functional and able to circulate blood, giving hope that one day we will be able to grow usable replacement limbs for amputees. Anthony and Jeff are excited about the possibilities, but wonder about the fate of the rats on whom these new arms were tested. Also, Anthony reveals his darkest physical secret.
