Japanese stem cell fraud leads to a new retraction

Last March, we reported on the retraction of a 2017 paper in Stem Cell Reports by Kohei Yamamizu and colleagues for widespread fabrication of figures. Turns out the problems were at least five years older than that.

Yamamizu had received a pink slip from his institution, the Center for iPS Cell Research and Application (CiRA), which had put the blame for the misconduct squarely on his shoulders. (The director of the institute, Nobel winner Shinya Yamanaka, also took some of the blame in a public statement in which he said he bore “a strong responsibility for not having prevented research misconduct at our institute.”)

Yamamizu has a new retraction, but this time’s a bit different. Here’s the notice for the paper, “Protein Kinase A Determines Timing of Early Differentiation through Epigenetic Regulation with G9,” which appeared in Cell Stem Cell in June 2012 (Yamanaka was not a co-author on either study).  Although the statement acknowledges the internal investigation, it doesn’t mention misconduct or name Yamamizu: Continue reading Japanese stem cell fraud leads to a new retraction

Journal retracts paper by controversial Australian journalist

Maryanne Demasi

The Journal of Biological Chemistry (JBC) has retracted a 2003 paper that resulted from the PhD thesis of Maryanne Demasi, an Australian journalist whose reporting on statins and the risks of cancer from cell phones has been a lightning rod.

The move, for what the journal says was attempts to reuse images to represent different experiments, follows an investigation by the University of Adelaide into allegations of image manipulation in Demasi’s thesis. In the investigation, Demasi

“Unusual aspects” of a figure — aka a cartoon of Trump’s face in baboon feces — disappear from a journal

“In the original version of this Article, there were unusual aspects to the ‘Extract fecal DNA’ illustration in figure 1. These features have been removed.”

With those 25 words, “one of the greatest scientific Easter eggs in a long time” or an image that was “highly unethical,” depending on your point of view, disappeared from a paper from Scientific Reports. Continue reading “Unusual aspects” of a figure — aka a cartoon of Trump’s face in baboon feces — disappear from a journal

The waiting game: A university requests a retraction. Then it waits three years.

On June 25, 2015, following an investigation into the work of a then-graduate student at University College Cork in Ireland, the senior author of a 2014 paper in PLOS ONE requested its retraction. The paper, said senior author Zubair Kabir in an email to Iratxe Puebla, the journal’s managing editor, was “fundamentally flawed.”

Puebla responded on July 1, saying she would contact the graduate student — Olurotimi Bankole Ajagbe, corresponding author of the paper — and get back to Kabir. A few more emails, including one on Aug. 26, 2015, in which Ajagbe also requested the retraction, resulted. On August 31, Puebla wrote to Ivan Perry, head of Cork’s department of public health, where Ajagbe had been working on his PhD, to say she would discuss the case with colleagues and follow up.

And then Cork waited. Continue reading The waiting game: A university requests a retraction. Then it waits three years.

Is it game over for a cartoon of Trump’s face in baboon feces? A journal issues an editor’s note for “unusual aspects”

from https://doi.org/10.1038/s41598-018-20427-9

If you’ve been anywhere near Twitter this week, you have probably seen a paper from Scientific Reports that appears to contain a likeness of a certain U.S. president in a cartoon of baboon feces.

It was “one of the greatest scientific Easter eggs in a long time,” according to Jonathan Eisen of the University of California, Davis. Continue reading Is it game over for a cartoon of Trump’s face in baboon feces? A journal issues an editor’s note for “unusual aspects”

Two years after he shared a draft of a “random brain fart side-project,” an astronomer sees a version published — without his name

Peter Yoachim

In 2015, Peter Yoachim became interested in how long astronomers remained active astronomers or, more to the point, how long they continued publishing in astronomy.

Yoachim, an astronomer at the University of Washington in Seattle, dug into some data, “did a burst of work in late 2015/early 2016, then fizzled out by 2017 when I ran out of time to work on it.” As he told Retraction Watch: Continue reading Two years after he shared a draft of a “random brain fart side-project,” an astronomer sees a version published — without his name

Political scientist asks for correction, gets flip-flop

Ryan Enos

You’d think that if an author asked a journal to correct a modest mistake, the journal would oblige. After all, many researchers have to be dragged kicking and screaming to correct the record.

But for Ryan Enos, a political scientist at Harvard, self-correction of a paper he had published in the Proceedings of the National Academy of Sciences (PNAS) took far more steps than one might have hoped. Continue reading Political scientist asks for correction, gets flip-flop

Anversa cardiac stem cell lab earns 13 retractions

Piero Anversa

Two months after Harvard and the Brigham and Women’s Hospital said they were requesting the retraction of more than 30 papers from a former cardiac stem cell lab there, two American Heart Association journals have retracted more than a dozen papers from the lab.

Yesterday, Circulation retracted three papers, and Circulation Research retracted 10. All 13 were among 15 subjected to expressions of concern last month. Continue reading Anversa cardiac stem cell lab earns 13 retractions

Indiana University paper about lung transplantation retracted after misconduct finding

After a finding of data manipulation, the corresponding author of a 2014 paper by a team of researchers at Indiana University has retracted the work.

Here’s the notice in Science Translational Medicine: Continue reading Indiana University paper about lung transplantation retracted after misconduct finding

Researchers retract PNAS paper when they realize they’d been victims of an antibiotic switcheroo

Gentamicin B1, via PubChem

In March 2017, a group of researchers in Vancouver, along with a colleague in Philadelphia,  published a paper in the Proceedings of the National Academy of Sciences (PNAS) concluding that a particular antibiotic might be useful for treating conditions in people with rare mutations.

Then, this past July, while continuing the work, they had an unexpected result. That made them suspect that the antibiotic they thought they had ordered, gentamicin, wasn’t what they thought it was. With the help of a different company that sells the antibiotic, they confirmed they were studying a different compound — and retracted the paper.

Here’s the notice for “Gentamicin B1 is a minor gentamicin component with major nonsense mutation suppression activity:” Continue reading Researchers retract PNAS paper when they realize they’d been victims of an antibiotic switcheroo
