and they have a better idea: They are working on using animal parts for transplants.
Maybe in the tuture our cliciucs vill nut be limited to bionic devices and transplanu operations. Maybe science will take us in another direction. Consider the salamander. If it loses a leg, it can grow a new one. What if a person who lost a hand or a kidney could grow a new one? This may sound like something from another sci-fi movie, but it could happen. Researchers are studying the genes that let salamanders grow new legs, and they hope to learn how human beings might do the same thing. Growing a new part of the body could be the best way to go. On the other hand, some people, if they had the choice, might prefer bionic devices. In sci-fi movies, you may have seen people become cyborgs half human being, half machine with bionic parts that give them special powers, such as super-human speed or strength. Think about it. If bionics could turn you into a superman. what would you do?
