Editor of another journal where Wagers and Mayack published an abstract is monitoring the situation

Yesterday, we noted that Amy Wagers and Shane Mayack have published five papers together. One of those, published earlier this year in Nature, was retracted Wednesday, and another is now the subject of a “notice of concern” from Blood.

We wanted to find out about some of the other papers published by Wagers and Mayack, so we contacted the editor of Developmental Biology, which published one of them. They have not heard from Wagers or Harvard, but are monitoring developments, according to editor in chief Robb Krumlauf: Continue reading Editor of another journal where Wagers and Mayack published an abstract is monitoring the situation

Errors, phantom author, retraction? It’s enough to set your teeth on edge

Authorship issues, sloppy science, deception — more often than not, at least one of these is at the heart of a retracted paper. But it’s rare when all three are involved. Which, of course, means that such a case is precisely what we’re about to deliver.

The Journal of Medical Case Reports, a BioMed Central title, recently retracted an intriguing item about a young man who developed a condition called pubic osteomyelitis after becoming infected with Streptococcus viridans following oral surgery to pull a wisdom tooth. As the authors, from Great Britain, explained in their 2008 paper describing the episode: Continue reading Errors, phantom author, retraction? It’s enough to set your teeth on edge

Blood posts “notice of concern” over second Wagers-Mayack paper

A day after an up and coming Harvard stem cell scientist retracted a Nature paper, Blood has issued a notice of concern about another paper by the same group, published in August 2008, the Boston Globe reports. Such notices often, but not always, precede retractions.

According to the notice for “Osteolineage niche cells initiate hematopoietic stem cell mobilization”: Continue reading Blood posts “notice of concern” over second Wagers-Mayack paper

Highly cited Harvard stem cell scientist retracts Nature paper

Amy Wagers, an up and coming stem cell researcher at Harvard who made a name for herself as a postdoc early by questioning the work of others, has retracted a January 2010 paper she co-authored in Nature. According to the retraction:

Three of the authors (J.L.S., F.S.K. and A.J.W.) wish to retract this Article after a re-examination of the publication raised serious concerns with some of the reported data. These concerns have undermined the authors’ confidence in the support for the scientific conclusions reported, specifically the role of osteopontin-positive niche cells in the rejuvenation of haematopoietic stem cells in aged mice. Although this matter is under further review, these authors wish to retract the paper in its entirety, and regret any adverse consequences that may have resulted from the paper’s publication. The retraction has not been signed by Shane R. Mayack, who maintains that the results are still valid.

What’s going on at Haematologica? Journal double-publishes three different studies

Sometimes, studies are so nice, you want to print them twice. But when that happens three times within a year, well, maybe it’s not so nice. Consider the following three retractions, which appeared on a single page of Haematologica last month.

One:

The Haematologica Production Office erroneously double-published the article entitled “P39/Tsugane cells are a false cell line contaminated with HL-60 cells and are not suitable for mechanistic studies in myelodysplastic syndromes” by David P. Steensma. Haematologica. 2010 Feb 23. [Epub ahead of print] with doi:10.3324/haematol.2009.022988 . This article must therefore be considered as retracted, as the correct version of the same article has been correctly published on July 1, 2010, as doi:10.3324/haematol.2010.022988. Haematologica sincerely apologizes to the authors and the readers for this mistake.

Two: Continue reading What’s going on at Haematologica? Journal double-publishes three different studies

Do plagiarism, fraud, and retractions make it more difficult to trust research from China?

Yesterday, we blogged about the retraction of a paper in the Journal of Clinical Rheumatology from a research team in China. The paper — claiming that tai chi helped women with arthritis — was riddled with inconsistencies and plagiarism.

Today, plagiarism and fraud made the front page of the New York Times.

Coincidence? Continue reading Do plagiarism, fraud, and retractions make it more difficult to trust research from China?

Rheumatology journal retracts tai chi-arthritis paper over fraud concerns

Most retractions happen in the dark: An article appears in print. One day it is withdrawn, with only a brief paragraph or two on the page to alert us to its fate.

On rare occasions, however, the process is more transparent, and when that happens it’s like the publishing equivalent of a supernova, a chance to glimpse in (here’s where the cosmic analogy stalls) almost real-time the retraction as it unfolds.

Here’s one of those unusual events.

The Journal of Clinical Rheumatology this week has retracted a March 2010 paper by Ni and colleagues in China, in which the authors reported that elderly women with osteoarthritis of the knee gained significant improvement in physical function and pain from a six-week course of tai chi. That claim is hardly controversial—other researchers have produced similar results and published studies of tai chi’s benefits for arthritis patients date back nearly a decade on Medline.

But the appearance of the article prompted an extraordinary letter to the journal, also published this week, from Chenchen Wang, of Tufts University, who smelled a rat. (Wang recently published a study of tai chi and fibromyalgia in the New England Journal of Medicine, which was criticized by some.) Of the Ni paper she writes (we added a link): Continue reading Rheumatology journal retracts tai chi-arthritis paper over fraud concerns

Beyond retractions: A technique gets an obituary

Sometimes, apparently, a retraction isn’t enough to put research findings to bed forever. Consider this obituary recently posted online at the Journal of Pediatrics, for a method of detecting gastroesophageal reflux disease (GERD) in children:

We commonly recognize the contributions of distinguished members of the pediatric community and, with regret, their passing. It is appropriate, therefore, that we acknowledge the timely death of an old friend, the pH probe. Crushed to death under the weight of evidence against it, it was found abandoned in a trash can with a note that read, ‘‘Good riddance to a bad test.’’

To be fair, the pH probe has always been the standard bearer for mediocrity.

The obituary goes on: Continue reading Beyond retractions: A technique gets an obituary

Microbial reproduction: Plagiarism from Wikipedia, elsewhere leads to retraction of biotech paper

When is an advance not an advance?

Biotechnology Advances has retracted a 2008 review by researchers in India who allegedly stole chunks of their manuscript from several sources including journal articles, Wikipedia, and StateMaster.com, a statistics clearinghouse.

According to the notice, the article, titled “Microbial production of dihydroxyacetone” Continue reading Microbial reproduction: Plagiarism from Wikipedia, elsewhere leads to retraction of biotech paper

2009 Cell paper on muscular dystrophy gene link retracted

A Cell paper reporting on genetic mutations responsible for a form of muscular dystrophy was retracted earlier this month. According to the retraction:

Our paper reported the identification of mutations in the gene VMA21 in patients with X-linked myopathy with excessive autophagy (XMEA) and characterized the molecular mechanisms underlying the disease phenotype. Many of the figure panels in the paper summarize data from multiple experiments. We have now detected a number of errors in these panels. Although we stand by the validity of our conclusions, we believe that the most responsible course of action is to retract our paper. We are preparing an expanded version of our work for future submission. We deeply regret this circumstance and apologize to the community.

One of the original authors, Dr. Aubourg, could not be reached regarding this Retraction.

The study has been cited 11 times, according to Thomson Scientific’s Web of Knowledge. Here’s a press release the researchers’ hospital, Sick Kid’s of Toronto, sent out when it was originally published.
