Incidentally, and as Dr. Zerhouni pointed out at the 2007 BioVision.Nxt meeting, the NIH (US) supports international research, so this, in effect, is an interesting issue for all. I think that there are also some key lessons with regard to economics. Unprecedented growth in budget allocations... stagnant budgets = lots of trainees/postdocs...
