  1. Riken CDB (Center for Developmental Biology) convened a committee to investigate the STAP fiasco. According to a news report in today’s Mainichi Shinbun newspaper (sorry, so far only available in Japanese) the CDB director, Dr. Takeichi, arbitrarily deleted certain portions of this committee’s report before it was made public. http://headlines.yahoo.co.jp/hl?a=20140708-00000012-mai-sctch Will post a link to the English story if/when it comes out.

    Such actions are reminiscent of Watergate. In the end, Nixon was undone by the efforts at a coverup, which gradually unraveled. The same thing seems to be happening to Riken now. The damaging details are dripping out a little at a time.
