This lecture, which took place at my school, was essentially a fascinating ramble about science and how far we should experiment with medical research. The main essence of the lecture was that we must tread very carefully with respect to medical research, but it is not justifiable to stop simply because of fear of the unknown. Professor Winston also discussed the experiments in Nazi Germany on Jews as an extreme exception to the rule. We were told about his research in transgenetic technology (altering the genome of an organism by the transfer of gene/s between species), and how he is helping attempts to be able to mature eggs outside the body. I found this lecture deeply interesting, and it was real food for thought with regard to medical ethics.
