On the ethics, in my former life I used to run a bioethics centre, and one National Academy committee's recommendation had to do with this culture of responsibility. Let me just tell you a story.
A guy called George Church is one of the world's pre-eminent producers of bits of DNA, and some next-generation threats are associated with some of those life sciences procedures. He's an excellent role model for his students. He talks about the ethical issues of biosecurity. He actually keeps track of all his students and what happens afterwards. So a lot of work can be done, I think more in the informal curriculum and role modelling, even more so than in the formal curriculum. That work, yes, around pathogens, but also around life sciences, folds very much into next-generation threats.
