Astrophysicists issue two detailed corrections

1.coverA group of astrophysicists has notched a pair of corrections for papers on galaxy clusters, thanks to an error that affected several figures in the papers, but not the overall conclusions.

The errors came in the catalog of “mock” galaxies that first author Fabio Zandanel, a postdoc at the University of Amsterdam, created to model features that are found in clusters of galaxies. Two mistakes canceled each other out “almost perfectly,” says Zandanel, making the changes that resulted from them subtle.

Zandanel explained the errors to us:

Diederik Stapel now has 58 retractions

stapel_npcSocial psychologist Diederik Stapel has notched his 58th retraction, after admitting he fabricated data in yet another article.

He’s holding onto his 4th place spot on our leaderboard.

This latest retraction is for “Correction or comparison? The effects of prime awareness on social judgments,” published in the European Journal of Social Psychology. As usual for Stapel, this paper has been retracted because he fabricated data.

Here’s the note:

Cropped, spliced image leads to a PLOS One correction

Screen Shot 2015-10-01 at 4.27.21 PMA PLOS One paper on morphine treatment for cancer cells has a couple issues with figures, prompting a massive correction — what we affectionately call a “mega-correction” — by the journal.

In one figure, there was “an undisclosed splice.” Another figure contained two panels that were “mistakenly from the same sample.”

The 2013 paper in question, “Chronic Morphine Treatment Attenuates Cell Growth of Human BT474 Breast Cancer Cells by Rearrangement of the ErbB Signalling Network,” has been cited four times, according to Thomson Scientific’s Web of Knowledge.

Here’s the correction:

Psychologist Jens Forster settles case by agreeing to 2 retractions

Jens Förster

Following questions about the veracity of multiple papers by his former employer, high-profile social psychologist Jens Förster has agreed to retract two papers as part of a deal with the German Society for Psychology (DGPs).

Last year, Förster had a paper retracted at the request of his former employer, the University of Amsterdam (UvA). In May, an investigation commissioned by UvA found that many of his experiments looked “too good to be true,” and eight papers showed strong signs of “low veracity.”

Just two of those papers are acknowledged in the settlement of a case by the DGPs against Förster, who currently works at Ruhr University Bochum. Here’s a translation of a notice from the DGPs from One Hour Translation:

BMC retracts paper by scientist who banned use of his software by immigrant-friendly countries

Screen Shot 2015-11-10 at 12.24.42 PMA BioMed Central journal has pulled the paper of a scientist who decided to prohibit countries that are friendly to immigrants from using his software.

Recently, German scientist Gangolf Jobb declared that starting on October 1st scientists working in countries that are, in his opinion, too welcoming to immigrants — including Great Britain, France and Germany — could no longer use his Treefinder software, which creates trees showing potential evolutionary relationships between species. He’d already banned its use by U.S. scientists in February, citing the country’s “imperialism.” Last week, BMC Evolutionary Biology pulled the paper describing the software, noting it now “breaches the journal’s editorial policy on software availability.”

Many scientists have used Jobb’s software: The BMC paper that describes it, “TREEFINDER: a powerful graphical analysis environment for molecular phylogenetics,” has been cited 745 times since it was published in 2004, according to Thomson Scientific’s Web of Knowledge.

Jobb told Retraction Watch that the software is still available to any scientist willing to travel to non-banned countries, and that he does not care about the retraction: Continue reading BMC retracts paper by scientist who banned use of his software by immigrant-friendly countries

University investigating duplicated images in retracted paper

Cell MetabolismThe authors of a Cell Metabolism paper are pulling it after discovering blot images that “appear more than once in independent and unrelated experiments.” 

Just how the duplication occurred in the 2009 paper — about transcription of mitochondrial DNA — remains a mystery, the authors note:

…the reasons for the errors are still under investigation…

Meanwhile, we’ve learned that the last author on the paper — Carlos Moraes of the University of Miami — has requested a retraction for another 2013 paper in Mitochondrion, also co-authored by Tina Wenz at the University of Cologne in Germany. That paper is among multiple publications co-authored by Moraes and Wenz that have been flagged on PubPeer.

We’ve reached out to the parties involved, and received a warning from an attorney representing Wenz that if we write about Continue reading University investigating duplicated images in retracted paper

Diederik Stapel retraction count updated to 57

stapel_npcWe’ve learned about two more retractions we missed for Diederick Stapel, the Dutch social psychology researcher who has now racked up a total of 57 retractions by our count.

Both retractions were issued after a committee released a report which established fraud in dozens of papers co-authored by Stapel.

Stapel is still #4 on our leaderboard.

“Insufficient permission” from funder resects liver disease paper

HepatologyA study on chronic liver inflammation was pulled from the journal Hepatology because of “insufficient permission by the authors’ funding institution to submit and publish the manuscript.” 

The paper, which was published in July, looked into how steatosis, the abnormal retention of fat in the liver, turns into steatohepatitis, also known as fatty liver disease. Researchers found that Treg cells play a central role in controlling the disease.

Unfortunately, the journal’s managing editor didn’t provide any information about the nature of the permission problems, and the notice doesn’t give any details.

Here it is, in full:

Boldt’s retraction count upped to 94, co-author takes legal action to prevent 95th

Screen Shot 2015-09-16 at 12.12.13 AM

We’ve found two recent retractions and an expression of concern for Joachim Boldt, former prominent anesthesiologist and currently Retraction Watch leaderboard’s 2nd place titleholder. He now has 94 retractions.

One of the retracted articles contains falsified data, along with a researcher who didn’t agree to be a co-author, according to an investigation by the Justus Liebig University Giessen, where Boldt used to work. The expression of concern is regarding some questionable data. The other new retraction is actually one of 88 papers that a group of editors agreed to retract back in 2011, after they were “unable to verify” approval by the Institutional Review Board (IRB) for the studies.

One of those 88 papers, we’ve discovered, has still has not been retracted. According to an editor at the journal, they haven’t removed it because one of Boldt’s co-authors has threatened them with legal action. Continue reading Boldt’s retraction count upped to 94, co-author takes legal action to prevent 95th

Authors pull Science paper on molecular wires for “inappropriate data handling”

pic.mag.current-issueThis week’s issue of Science includes a retraction of a highly cited paper about manipulating the current in a string of molecules with a magnet, after an investigation by the co-authors revealed “inappropriate data handling” by the first author.

According to the note, the co-authors’ suspicions arose when they tried to follow-up on the data. Following a “thorough investigation,” they concluded that first author Rabindra N. Mahato had handled the data in such a way that they could no longer trust the conclusions. In the end, Mahato agreed to the retraction.
