just one comment on this story.

Not trying to take away the contribution of 普瑞舍. He generated a great tool, but if it is kept in his hands without sharing to others, this study might not get a nobel at all. 钱永健 made the best use of this tool and has shown everybody else the potential of this gene. It is not only GFP, but many other genes. Clearly 钱永健 is the major contributor to this field. Again, I am not trying to argue against the contribution of  普瑞舍.
