David Cyranoski “Researcher’s death shocks Japan” http://blogs.nature.com/news/2014/08/researchers-death-shocks-japan.html
But lately he had been immersed in controversy over two papers, published in Nature in January, that claimed a simple method of creating embryonic-like cells, called stimulus-triggered acquisition of pluripotency (STAP). Various problems in the papers led to a judgement of scientific misconduct for their lead author, Haruko Obokata, also of the CDB. The papers were retracted on 2 July.
Sasai, who was a co-author of both papers, was cleared of any direct involvement in the misconduct. But he has been harshly criticized for failure of oversight in helping to draft the paper. Some critics, often on the basis of unsupported conjecture, alleged deeper involvement of the CDB. An independent committee recommended on 12 June that the CDB, where Sasai was a vice-director, be dismantled. Sasai had been instrumental in launching the CDB and helped it to develop into one of the world’s premier research centres.
