sorry, 上次的印象有误。我的这个印象是因为有次上课的时候，老师讲到prion的发现。。我记得老师是说，both the person who drew the hypothesis and the scientist purified the hypothetical infectious prion were awarded the Nobel prize. however, Now I realized it is only the scientist Prusiner who purified the prion was awarded the Nobel prize at 1997. my memory was wrong. Now i recalled and realized that the lecturer said that people could still publish an pure hypothesis on "Nature" (that was a hypothesis published on 1960's) in the old time, however, it is impossible to do so nowadays. 所以我说的应该是，以前一个假想可以在nature上发表，现在不可能。。。说诺贝尔奖太大了。
