I've never regretted a swim

Animal experimentation has been essential to the development of all cardiac surgery, transplantation surgery, joint replacements and all vaccinations.

Post-operatively the transplanted kidney functioned immediately with a dramatic improvement in the patients renal and cardiopulmonary status. This spectacular success was a clear demonstration that organ transplantation could be life-saving.

Is the Church inimical to science? Growing up as a Catholic and a scientist - I don't see it. One truth is revealed truth, the other is scientific truth. If you really believe that creation is good, there can be no harm in studying science. The more we learn about creation - the way it emerged - it just adds to the glory of God. Personally, I've never seen a conflict.

The slow rejection of the foreign skin grafts fascinated me. How could the host distinguish another person's skin from his own?

Stem cells are probably going to be extremely useful. But it isn't a given, and even if it were, I don't think the end justifies the means. I am not against stem cells, I think it's great. Blanket objection is not very reasonable to me-any effort to control scientific advances is doomed to fail. You cannot stop the human mind from working.

I was performing skin grafts and became interested in why skin wouldn't graft permanently.
