Jeff sez, "Researchers often use Photoshop to clean up the images they produce in the laboratory. If the experiment didn't go quite right, a bit of tampering can make a gel look like things did work. Editors at Science, Nature, and other journals are turning into detectives, using new tools to hunt for fraudulent images."
