The investigation, conducted by a government-funded Japanese research institute called RIKEN, found that three photos in one of the papers don't show the results that they claim to. The investigating committee placed the blame on the paper's first author, Haruko Obokata, a postdoctoral researcher at RIKEN who is still early in her career in science. Two of the troubled photos come from research Obokata did as a graduate student, RIKEN says. That research didn't use the same procedures as Obokata and her team claimed to use in the new papers, so it isn't legitimate to transfer them over. The new papers were published in January. Since then, they've gotten a lot of attention from scientists, news media, and ordinary folks.
