With recent revelations of misconduct involving its research on so-called STAP cells, stem cell researcher Haruko Obokata and her employer, Riken Institute, have come under intense scrutiny and criticism.

Last week, the nation¡¯s largest science research institute announced an ¡°action plan¡± to avoid similar scandals from recurring. It remained vague on whether STAP cells really exist, as claimed by Obokata, despite the recent retractions of two STAP papers authored by a team of researchers led by her that claimed to have discovered a new kind of cell that could grow into any type of tissue in the body.

Although the government-backed institute has a track record of producing Nobel Prize-winning researchers, it now faces massive pressure to clean up its act and regain the trust of officials and the public alike.
