"FILE - In this Jan. 28, 2014 file photo, researcher Haruko Obokata, the lead author of a widely heralded stem-cell research paper by the Japanese government-funded laboratory Riken Center for Development Biology, speaks about research results during a news conference in Kobe, western Japan. The scientists who reported in January that they'd found a startlingly simple way to make stem cells have withdrawn that claim, following accusations of falsified data. On Wednesday, July 2, 2014, the journal Nature released a statement from the scientists who acknowledged ""extensive"" errors and said they couldn't say ""without a doubt"" that their method works.
