Among the many temptations of the digital age, manipulation of photographs has proved particularly troublesome for science  Recently, a journal of cellular biology began using a software tool to examine the digital images submitted along with articles for publication  It discovered that dozens of authors had submitted digital images that had been manipulated in ways that violated the journal' s guidelines
Clearly, scientific fraud is a widespread problem among the authors submitting to that journal
Many of the scientists who submitted articles with manipulated images did so in order to misrepresent the information conveyed by those images.
