Perhaps the best route is in the question where you are urged to look at new scientific procedures. Those mentioned previously are certainly worth investigating. There are also some that involve stem cells--actions which some are against for moral and religious reasons. One such procedure involves an attempt to alter a genetic predisposition to rhumetoid arthritis.
The question is not clear -- have you given us the question exactly as it has been asked to you?
I think that your teacher is pointing out that Victor's ambition has contaminated science. Because Victor is ambitious, he does things that should not be done.
I think, then, that perhaps you are supposed to be looking for articles that could show this same process occurring in our society today. Perhaps you could look at things like stem cell reserach or cloning or genetically modified organisms -- these are all things that (some might say) show scientists doing things that should not be done (perhaps because of their ambitions).
