While the President's advisory council debates what policies to recommend on issues of cloning and stem cell research, it's possible to purchase eggs on the internet. Drug companies and other commercial enterprises are patenting genes and biological processes - even before knowledge is complete about how they work. Consumers are often desperate ...
