The “regression to the mean project:” What researchers should know about a mistake many make

The work of David Allison and his colleagues may be familiar to Retraction Watch readers. Allison was the researcher — then at the University of Alabama, Birmingham, now at Indiana University — who led an effort to correct the nutrition literature a few years ago. He and his colleagues are back, this time with what … Continue reading The “regression to the mean project:” What researchers should know about a mistake many make

When researchers from a particular country dominate retraction statistics, what does it mean?

The Retraction Watch Leaderboard of authors with the most retractions is a frequent source of comment and speculation. Why do only men appear on it? And what fields and countries are represented? Here, Iekuni Ichikawa, Project Professor at Shinshu University and Emeritus Professor of Pediatrics at Vanderbilt University, as well as a co-founder of the Association for … Continue reading When researchers from a particular country dominate retraction statistics, what does it mean?

How a typo in a catalog number led to the correction of a scientific paper — and what we can learn from that

Papers are corrected for lots of different reasons. In this guest post, Anita Bandrowski, who leads an initiative designed to help researchers identify their reagents correctly, describes one unusual reason for a correction — and explains what researchers can learn from the episode. Last December, Tianyi Wang and her colleagues published a very interesting paper … Continue reading How a typo in a catalog number led to the correction of a scientific paper — and what we can learn from that

What should happen to a paper published by Theranos?

Last December, a group of scientists at a biotech firm published a paper on a “miniaturized, robotic clinical laboratory.” The technique, according to the authors, “would benefit patients and physicians alike.” Nothing terribly unusual there. But what was — and what caught the eye of a Retraction Watch reader — was the name of the … Continue reading What should happen to a paper published by Theranos?

“[T]he data and findings…are unreliable:” Authors explain how a refutation came to be published in the same journal as the original

A group of tiny, all-female animals called bdelloid rotifers has long fascinated scientists. Among other questions, of course, is: Why haven’t they gone extinct, if they can’t mix up their genes? In 2016, a group of authors published a paper in Current Biology claiming to show that rotifers could swap DNA the way bacteria do. … Continue reading “[T]he data and findings…are unreliable:” Authors explain how a refutation came to be published in the same journal as the original

Researchers pull Nature paper over first author’s objections

Researchers have retracted a 2015 Nature paper about the molecular underpinnings of immune function after discovering they could not replicate key parts of the results. The first author, Wendy Huang — who started working as an assistant professor at the University of California, San Diego, only months after the paper appeared — did not sign … Continue reading Researchers pull Nature paper over first author’s objections
