The article discusses the suicide of Yoshiki Sasai, a stem-cell biologist at the RIKEN (Rikagaku Kenkyusho) Center for Developmental Biology, and supervisor of Haruko Obokata, a researcher found guilty of fabrication and plagiarism for two papers published in the January 2014 issue of "Nature" purporting to have developed a simple method of creating stem cells. The author argues that Sasai was innocent of any wrongdoing and questions whether pressure put on scientists to make discoveries is not to blame.
