Thanks HunHunSheng for the link. Ms Yu seems to be a nice honest girl.
After listening to her talk, now I understand that her lab just used human genes instead of mice genes for the screening work. Sure it is hard work and lots of labor involved, but the experiment is not original as the Japanese did first, and most importantly,it seems there is no explanation for this phenomenon in terms of elucidating the mechanism. So it is not possible to get Noble Price.
