I'm pretty much a science noob. When some lab discovers a new process for fertility, or a new genetic test, or a new method for making clones or stem cells or whatever, how is this process or method shared? Or is it shared? Do they go out and get patents? Guard their secrets? Share them for the benefit of mankind, sell them, what? A good example is Venter's announcement that his group is close to what he calls artificial life. Will he be sharing the procedures he develops? If so, with whom, and how? Are there any books or other learning materials that explain everything a curious person could want to know about these aspects of the culture/business/whatever of life sciences, medical sciences, etc?
