Back in April, chemist Ronald Breslow published a fairly routine research paper on the topic of molecular evolution. His paper concluded with a left turn into dire warnings about the possibility of dinosaurs on other planets. Sadly, this paper has now been recalled by the Journal of the American Chemical Society. Essentially, they unpublished it. The reason: The paper turned out to be a bit too similar to two other studies that Breslow had published previously. Yes, including the part about the space dinosaurs.
