Everyone knows that ethics is influenced by culture. But there seems to be the start of a migration of scientists in the stem cell research area to Asia. Apparently many Asian religions worry less than western religions about "playing god", and take a much more liberal view to cloning. Exellent article and debate on the subject in an article in the New York Times by John Tierney entitled "Are Scientists Playing God? It Depends On Your Religion". The additional links to books are articles are particularly interesting.
