Some outside scientists soon noticed the papers had problems, however. Critics wondered if some of the data were made up, or manipulated to look better. The institute where the papers' lead author works as a research scientist, RIKEN of Tokyo, investigated the author, Haruko Obokata. In April, a RIKEN committee found Obokata guilty of "scientific misconduct." Another RIKEN committee will decide her punishment, Nature News reported at the time.
