There are calls in the Roman Catholic Church to excommunicate researchers who use embryos in their stem cell research. Although I have heard many people active in the science and medical communities call for a convergence of science and the humanities, in order to bring an ethics dimension into the decision process, I don't think this is quite what they had in mind. This article entitled "Excommunication is sought for stem cell researcher " by Elisabeth Rosenthal in the New York Times talks about the issues. We have disconnected science and religion in the last 300 years or so (remember when Copernick had to swear the sun moved around the earth...), and science has been able to move forward at an incredible rate. We are now reaching the limits of this single minded approach, and the use, or rather misuse, of innovations and discoveries needs to be taken into account. But an interference of the Roman Catholic Church with an edict on what can or cannot be done under threat of excommunication smacks of sanctions of a bygone era.
