Launched in 2010 by science writers Ivan Oransky and Adam Marcus, Retraction Watch seeks to make public the "self-correcting" nature of science. The site has been praised for bringing to light many hundreds of retracted papers in a wide variety of fields, some due to fraud, others just to mistakes in experiments or the publishing process. A great place to start is with the latest retractions, listed in chronological order on the homepage. For instance, recent retracted papers at the time of this writing concerned plagiarism in the field of aeronautic dentistry, a paper on wheat straw that seems to have been published (and retracted) more than once, and even a letter to the Journal of the American College of Cardiology, written by an impersonator. The site also contains a useful search function for readers who are looking for specific topics, authors, or articles.
