Nature Publishing Group covered up alleged scientific misconduct such as mega-image manipulation by accepting mega-correction many times.
Examples of inappropriate mega-correction in Nature
1) Shigeaki Kato's case:http://katolab-imagefraud.blogspot.com/2012/01/dna-demethylation-in-hormone-induced.html
2) Issei Komuro's case:http://isseikomuro.blogspot.com/2013/05/nature-2008-jul-174547202345-9.html
Besides, In Jan, 2014, Nature Publishing Group replaced the following misused image data in Supplemental Fig. 2c with new one without any notice in the Nature Medicine article (2009 Sep;15(9):)! Please compare the following old images and new images. (New image: http://www.nature.com/nm/journal/v15/n9/suppinfo/nm.2014_S1.html).
Can Nature Publishing Group, which is tolerant of misconduct, properly deal with issues in Dr. Obokata's papers on STAP cells?
