We might be able to live forever, thanks to a mouse. An experiment was succeeded by Dr Jay Vacanti in 1997. In the experiment, an ear can be grown on the back of a mouse. Therefore, this result indicates that any organ can be "grown" in the near future. This seems a perfect cure for humans, especially those who lost their ears or other parts of their body.
However, the success of this experiment should be discussed in terms of morality. If this experimant was applied to practical use, human can make evry organ which they want. It means humans can live literally forever. We maight be able to clone a human by using this method. It is against human ethics, and we have to think about that carefully.
