Another Cell retraction, and more questions than answers

A new retraction has appeared in the journal Cell. The article, “DNA-PKcs-PIDDosome: A Nuclear Caspase-2-Activating Complex with Role in G2/M Checkpoint Maintenance,” had initially appeared in February 2009.

According to the notice: Continue reading Another Cell retraction, and more questions than answers

Where did I park my car? Psychological Science retracts working memory study

In what might be considered a model for how retraction notices should look, Psychological Science has retracted a 2008 paper, “Gaining control: Executive training and far transfer of the ability to resolve interference.” According to the notice — which includes two tables: Continue reading Where did I park my car? Psychological Science retracts working memory study

Another retraction of Spirocor research

Remember Spirocor, the Israeli company that closed down a clinical trial involving its “respiratory stress” test for coronary artery disease because the data underpinning the validity of the method proved unreliable? The problem led to the retraction of two articles, about which we’ve previously reported. But we also found a study by some of the same researchers, who include scientists in Israel and the United States, that had been presented at the 2010 meeting of the American Heart Association and published in the journal Circulation.

That abstract, No. 14426 “Accuracy and Usefulness of Finger Pulse Wave Analysis during Brief Deep Breathing Exercise (Respiratory Stress Response) as a Marker of Significant Coronary Artery Disease,” has now been retracted — making, to our knowledge, the entire body of published research on the Spirocor product an editorial memory.

Here’s the notice, which appears within the text of the abstract: Continue reading Another retraction of Spirocor research

In a retraction’s wake: Postdoc Shane Mayack, dismissed from Amy Wagers’ stem cell lab, speaks out

 

Last October, Retraction Watch readers will recall, up-and-coming stem cell researcher Amy Wagers retracted a study in Nature describing how her team rejuvenated blood-forming stem cells in older mice. Shane Mayack, a postdoc in Wagers’ lab who had been dismissed after an inquiry into what happened, did not sign that retraction. Since then, Mayack has not spoken to the press, except for a brief comment to Nature through her attorney.

Here, we present, unedited, Mayack’s side of the story. While accepting responsibility, she also has a number of suggestions for how universities and journals can handle these situations better. Shane can be reached at smayck[at]yahoo.com.

Since it was well covered by this blog, the readers of Retraction Watch are no doubt aware that in October 2010, a paper that I co-authored was retracted from Nature and a notice of concern was posted regarding a second paper published in Blood.

So, what went wrong? Continue reading In a retraction’s wake: Postdoc Shane Mayack, dismissed from Amy Wagers’ stem cell lab, speaks out

More on Applied Mathematics Letters: Journal retracted paper questioning second law of thermodynamics

Have you read yesterday’s post on a retraction in Applied Mathematics Letters yet? (If you haven’t, you’ve missed the explanation of how “Both science and spirituality came from space,” along with other oddities. We’ll wait while you go read it.) But for those of you who have, it turns out that this wasn’t the first retraction of a bizarre paper in the journal this year.

In January, Granville Sewell, of the University of Texas, El Paso’s math department, published a paper there called “A Second Look at The Second Law.” Its abstract: Continue reading More on Applied Mathematics Letters: Journal retracted paper questioning second law of thermodynamics

Aftermath: Gut-wrenching misstep leads to retraction, frayed feelings and a paperless postdoc

Graham Ellis-Davies says January 25th was one of the worst days of his life. That was when the journal ChemBioChem retracted an article, published barely two weeks earlier, for a mistake Ellis-Davies blames squarely on himself.

The fallout has been nearly two months of painful self-recrimination, a tattered friendship and, perhaps most significant, he adds, the wasted effort of a postdoc who poured months of research into a now worthless publication. Continue reading Aftermath: Gut-wrenching misstep leads to retraction, frayed feelings and a paperless postdoc

NEJM retracts Potti paper

About a month ago, the New England Journal of Medicine told us that they didn’t “have any plans” to retract a paper by Anil Potti. Apparently, they’ve changed their minds.

Today, they posted this retraction notice: Continue reading NEJM retracts Potti paper

A Nature chain retraction for Arabidopsis paper, and some unanswered questions

If a paper is retracted, should papers that cite it get retracted, too? We’ve been on the lookout for this kind of move, which we figure is consistent with cleaning up the scientific record. Today, one appears in Nature.

The original paper, “Mediation of pathogen resistance by exudation of antimicrobials from roots,” purported to show how a particular bug evades the immune system of Arabidopsis, a plant commonly used in the lab. It has been cited 51 times, according to Thomson Scientific’s Web of Knowledge.

The retraction notice says that the paper’s conclusions could no longer be supported because one of the key references — a paper in the Journal of Agricultural and Food Chemistry by many of the same authors — had been retracted: Continue reading A Nature chain retraction for Arabidopsis paper, and some unanswered questions

More on SPIROCOR noninvasive heart disease test: Second retraction (in fact the first) says little

Since we first wrote about the travails of Spirocor’s bedside, noninvasive test for coronary artery disease, we’ve been trying, without much success, to find out more information.

But as they say about every dog, our day has come.

As we initially reported, Ron Waksman, a prominent Washington, D.C. cardiologist and editor-in-chief of Cardiovascular and Revascularization Medicine, was first author of one of two papers about the Spirocor technology that were published in 2010. The other, by Shiyovich, et al, was retracted earlier this month by the American Journal of the Medical Sciences, which triggered our interest in this case.

At the time, we couldn’t find any evidence that Waksman’s article had been retracted, and Waksman has not responded to multiple requests for comment. Today we spoke with Kate Coons, the journal’s managing editor, who told us that the authors had sought a retraction for the article, “An innovative noninvasive respiratory stress test indicates significant coronary artery disease,” in December, and that it had posted one on its website on Jan. 6 of this year. It will be in print in an upcoming issue.

The notice is not available on Medline, but it can be found on ScienceDirect: Continue reading More on SPIROCOR noninvasive heart disease test: Second retraction (in fact the first) says little

“Biologist realizes he’s been studying Cadbury egg”: Mislabeled bottle leads to Phys Rev B retraction

The quote in the title of this post is a potential Onion headline that didn’t make it into print. It was part of an episode of This American Life that aired last week, and it seemed apropos, even though the subject here is superconductors rather than biology.

After all, we’ve written about a retraction that resulted from ordering the wrong mice. Today, we bring you the tale of a retraction caused by a mislabeled bottle. According to a retraction notice that appeared online last month in Physical Review B: Continue reading “Biologist realizes he’s been studying Cadbury egg”: Mislabeled bottle leads to Phys Rev B retraction
