Four genetics papers retracted for duplication

Petter Portin, of the University of Turku, Finland, has been forced to retract four papers because they were duplicates of work he had already published.

Two of those retractions appear in the February 2011 issue of Hereditas. Here’s one retraction notice (link added):

The following article from Hereditas: Portin, P. ‘The effect of the mus309 mutation, defective in DNA double-strand break repair, on crossing over in Drosophila melanogaster suggests a mechanism for interference’, published online in Wiley Online Library (http://onlinelibrary.wiley.com/) on 1 September 2009, Hereditas, volume 146, pp. 162–176, has been retracted by agreement between the author, the Editor-in-Chief, Anssi Saura, and John Wiley & Sons A/S. The retraction has been agreed due to prior publication of a similar article in Genetica.

*Grad student’s misdeeds may cost prof Carsten Carlberg a job

In November, we reported on two retractions in Cell and the Journal of Molecular Biology involving misconduct in the lab of biochemist Carsten Carlberg, of the University of Eastern Finland, in Kuopio.

Carlberg also holds an appointment in computational biology at the University of Luxembourg, which last year launched an investigation — at his behest, he says — into the case. Well, the officials in Luxembourg finally have spoken, and Carlberg, it seems, may soon be out of his job there, the Tageblatt newspaper reports.

Carlberg, to our knowledge, has never been accused of ethical violations in the case, and the inquiry didn’t change that. Rather, the bad actor appears to be his former post-doc graduate student in Finland, Tatjana Degenhardt. But the University of Luxembourg may seek to dismiss Carlberg after concluding that, as the senior author of the two retracted articles, he bore responsibility for the validity of the results and, by implication, the deception.

Ironically, Carlberg says he asked the school to undertake the investigation even though none of Degenhardt’s research had been conducted using that school’s resources. In an email today to Retraction Watch, he writes: Continue reading *Grad student’s misdeeds may cost prof Carsten Carlberg a job

Bulfone-Paus saga continues: Her supporters and home institution exchange sharp letters

Silvia Bulfone-Paus

Retraction Watch readers may have been following the case of Silvia Bulfone-Paus, whose lab has been forced to retract 12 papers amid allegations of scientific misconduct. As is often true in such cases, the story doesn’t end with those retractions. We’ve just become aware of a fascinating exchange in March and April between Bulfone-Paus’s supporters and her home institution, Germany’s Research Center Borstel.

First, some background: Karin Wiebauer, a former post-doc in Bulfone-Paus’s lab, flagged the potential misconduct, in great detail, for Bulfone-Paus in a November 2009 email. (In fact, she had brought it to her attention years earlier.) But Bulfone-Paus did not tell Borstel officials about the allegations until late February 2010. Borstel’s investigation into Bulfone-Paus’s lab began in July 2010.

Once that began, a person referring to himself as “Marco Berns” began emailing officials, journalists, and others about the situation. Nature called that move a “smear campaign,” and the emails “libellous,” but in retrospect they — and Wiebauer’s analysis — appear to have been spot-on, based on the eventual report of the Borstel committee. That report — which found data manipulation by two of Bulfone-Paus’s post-docs — led the institute’s Scientific Advisory Board to ask for Bulfone-Paus’s resignation. She only tendered that a month later, after more pressure.

So, with that as a preamble: If we were to characterize the letter, which we’ve made available here, we’d call it a good example of “shoot the messenger.” It’s signed by 25 scientists, starting with Desmond Tobin of the University of Bradford in the UK and ending with Andrzej Slominski of the University of Tennessee.

Three more chemistry papers fall to “serious errors” of unknown nature

Back in March, we reported that the journal Computational and Theoretical Chemistry (CTC) had retracted a pair of 2006 papers by a group of Iranian researchers. As the notices stated, the scientists had recalled their articles after detecting “serious errors” with the work post-publication.

At the time, the authors still had three other articles in good standing with CTC. No longer.

CTC has retracted the remaining three papers by the group, for the same “serious errors.” The articles appeared between 2007 and 2009, and were titled: Continue reading Three more chemistry papers fall to “serious errors” of unknown nature

Controversial paper critiquing climate change science set to be retracted because of plagiarism

A controversial study of how relationships between climate change scientists may affect the field, and that has been dogged by charges of plagiarism, will be retracted, USA Today reports.

The abstract of the 2008 paper in Computational Statistics and Data Analysis, by Edward Wegman and colleagues, concluded:

We conjecture that certain styles of co-authorship lead to the possibility of group-think, reduced creativity, and the possibility of less rigorous reviewing processes.

According to USA Today: Continue reading Controversial paper critiquing climate change science set to be retracted because of plagiarism

Psychology Today apparently retracts Kanazawa piece on why black women are “rated less physically attractive”

Psychology Today has apparently yanked a blog post by London School of Economics evolutionary psychologist Satoshi Kanazawa that wondered why black women were considered less attractive than other women.

The post, titled “Why Are Black Women Rated Less Physically Attractive Than Other Women, But Black Men Are Rated Better Looking Than Other Men?” was posted yesterday and available here, but that page now returns a 503 error.

A number of people have archived the post, however, including a communications and media professional who blogs at Chic.Seven. Her pdf is available here.

The post uses data from Add Health, a federally funded study:

Add Health was developed in response to a mandate from the U.S. Congress to fund a study of adolescent health, and Waves I and II focus on the forces that may influence adolescents’ health and risk behaviors, including personal traits, families, friendships, romantic relationships, peer groups, schools, neighborhoods, and communities. As participants have aged into adulthood, however, the scientific goals of the study have expanded and evolved. Wave III, conducted when respondents were between 18 and 26 years old, focuses on how adolescent experiences and behaviors are related to decisions, behavior, and health outcomes in the transition to adulthood.

Excerpts of the post, which really needs the graphs Kanazawa included — available at Chic.Seven’s blog — to be remotely comprehensible: Continue reading Psychology Today apparently retracts Kanazawa piece on why black women are “rated less physically attractive”

Another math paper retracted because of duplication

Last month, we brought you news of two retractions in math journals for duplicate publication and apparent guest authorship. Last week, we learned that the lead author of one of those papers, Amir Mahmood, has retracted another paper, this one in Nonlinear Analysis: Real World Applications.

According to the retraction notice, the paper was an “accidental duplication of an article that has already been published” in Communications in Nonlinear Science and Numerical Simulation.

The papers share two authors: Mahmood, of the department of mathematics at COMSATS Institute of Information Technology and the Abdus Salam School of Mathematical Sciences of GC University, both in Lahore, Pakistan; and N.A. Khan, of the University of Karachi’s math department. Khan was also on one of the two papers we wrote about last month, but not the one Mahmood co-authored. Those two papers’ shared author was M. Jamil.

Mahmood told Retraction Watch by email that the papers are not duplicates, and that the journal editors could not explain to him why they were.

Retraction Watch readers can be the judge. The abstract of the retracted paper: Continue reading Another math paper retracted because of duplication

Yes, Virginia, medical writers really do commit plagiarism, says a surgery retraction

Readers may recall a recent post on a study purporting to show that one of the best insurance policies against a retraction is to employ a medical writer. Well, a group of Iranian surgeons did just that. How’d it work out for them?

Of course, since you’re reading about this on Retraction Watch, you already know the answer to that one, don’t you?

The World Journal of Surgery has retracted a 2010 article written by hired guns who apparently decided to perform wordthievery rather than wordsmithery.

Here’s the notice (stated, oddly, as an “erratum” to the original paper): Continue reading Yes, Virginia, medical writers really do commit plagiarism, says a surgery retraction

Another unofficial record? Authors walk back arcane blue crab paper — 15 years later

If a paper that has never been cited is retracted, will it be missed?

Japanese researchers have retracted an obscure 1996 article in an equally obscure physics journal after concluding — some 15 years later — that their fundamental assertion was mistaken.

The paper, “Uptake and excretion of cobalt in the crustacean Portunus trituberculatus,” in  Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, purported to show that a form of the element cobalt might be helpful in tracing the growth of Portunus trituberculatus, otherwise known as the blue crab.

That’s the world’s most harvested crab species and a particular favorite in Asia. But don’t confuse it with the Chesapeake Bay blue crab, Callinectes sapidus, of William Warner’s Pulitzer Prize-winning book, Beautiful Swimmers.

The problem with such elemental tracers, it seems, is that crabs moult repeatedly, shedding their shells, along with the elements that build up inside them. According to researchers from the Research Institute for Advanced Science and Technology and the Osaka Prefectural Fisheries Experimental Station, however, a volatile form of cobalt, previously undetected, could be a suitable element for tracing the growth of both crabs and prawns — another important aquaculture species in Asia — over time.

But that turned out to be a (shell)fish tale. Per the retraction notice, which appears in the May 15, 2011 issue of the journal: Continue reading Another unofficial record? Authors walk back arcane blue crab paper — 15 years later

Blood retracts two, including a disputed paper from the Karolinska Institute

The journal Blood has two retractions this month, one of which seems particularly interesting. So let’s deal with the other one first.

The paper, “MicroRNAs 15a/16-1 function as tumor suppressor genes in multiple myeloma,” appeared online in October 2010. But according to the retraction notice, the authors

have recently discovered that the cell lines used in their paper were inadvertently misidentified. The cell lines utilized in the paper have now been found to contain the bcr/abl translocation and most likely represent the K562 CML cell line, instead of MMS1 and RPM1 myeloma cell lines. Due to this issue, the relevance of the findings to myeloma and thus, the conclusions of the paper, are not supported by the data. The authors apologize to the readers, reviewers, and editors of Blood for publishing these erroneous data.

That seems straightforward enough, and we couldn’t find any evidence that this problem affected other publications.

The second paper, however, could be more significant. Continue reading Blood retracts two, including a disputed paper from the Karolinska Institute
