Sweedish scientists have finally been able to creat a prosthetic arm/hand that feels what is is gripping.  The user can grip a water bottle without crushing it, pour themselves a drink and even turn a key in a lock using their prothesis.  Scientist also feel that this arm will help to aleviate phantom pain because it utilizes the nerves and cognitive centers from the missing limb to get the prosthetic to work.
