A; what are you reading about in that science magazine?
B: there are several interesting articles on recent scientific breakthroughs. I just finished reading one about cloning.
A: I'm not sure I like the idea of that. I don't want people copying me or other people. It could be very confusing.
B; according to the article, you have no real need to worry. Research nowadays is foussing on cloning parts of a human body to replace damaged or lost parts, not on recreating a whole human.
A: in the future, that could be possible.
B: in this article, scientists say that if you took the genes from someone and tried to create a copy of a person, there's no guarantee that the copy would look or act like the original!
A; really? What else have you discovered?
B: I read about how scientists are using material from plants and animals to create new medicines. For example, an animal be immune to disease that affects human. So, scientists find out why it's immune and recreate that immunity for human.
A; that's great, because it uses natural materials rather than ones that scientists make themselves. I prefer natural remedies to man-made ones.
