http://www.pbs.org/wgbh/nova/sciencenow/3209/04.html
The main character in our movie is a girl who has to suffer diabetes for a long time. She has had it since she was born. Her family and she still keep effort saving her own life. Although she lives with a disease that follow her many years, she still live normally. She has a exclusive diet and has to check her blood frequently : after every her meals or every time she wakes up. Doctors are really interested in this case and they try to find out a way to cure her disease. Doctors have been researching techniques of cloning that they think it can be helpful in this girl‘s disease. They made many experiments to discover how cells develop and replace old cells, and from there they can find way to renew a body with new cells and remove bad cells. In fact, scientists have tried to develop techniques to cloning people but they don’t really clone people. A scientist explained: we don’t really clone people but we can just clone the cell and for cell can double itself, it develops into a new body. An egg cell will be fertilized by putting a root cell in it and then transplant it into a bringer. That cells will develop into a new shape and create a new organism. This technique causes arguments because it offenses holy birth ability of the women. The first creature was created base on this technique is Dolly sheep. It caused a new important event in medicine but Dolly sheep just lived in a short time. Therefore, it is still not a perfect technique to save life. Scientists keep researching to find out a best ways to cure patients. A new question is made here is to save the life or start a new life.
