On the Media, a public radio show, recently covered the increase in the rate that scientific journal articles are being retracted by interviewing Ivan Oransky. From their description of this interview:
There's often a really interesting story behind a retraction. That's what Ivan Oransky told us. He's a doctor and journalist and founder, along with Adam Marcus, of a blog called Retraction Watch. They monitor scientific journals and investigate why articles were retracted. They uncovered serious ethical breaches at a variety of journals. We asked Oransky to tell us about some of the stories he's covered this year.Oransky discusses some of the reasons for the increase, including some anecdotes about the papers retracted, and the actions of some authors, editors, and publishers. Because, dismayingly, many retracted papers continue to be cited, he suggests changes in how these papers are marked in the scientific record to reflect the fact that they have been retracted.
