After being “blindsided” a few months ago when she was told one of her 2005 papers was going to be retracted, a researcher scrambled to get information about why. And when she didn’t like the answers, she took to PubPeer.
Eight days ago, Shalon (Babbitt) Ledbetter, the first author of the 2005 paper published in Cell, posted a comment on the site announcing the paper was going to be retracted after the last author’s institution, Saint Louis University (SLU), determined that some figures had been manipulated by the last author, Dorota Skowrya. A letter dated September 2, 2015 sent by SLU to Cell describes the results of the investigation — namely, that the manipulations were “cosmetic,” and had no effect on the data or the conclusions. More than two years later, Ledbetter learned the journal was planning to retract the paper, and an initial draft of the notice wouldn’t identify who was responsible; she has since been pulled into a confusing web of blame-shifting and conflicting information that has been, in her words, “heartbreaking.”
An investigation by Kyoto University in Japan has found a researcher guilty of falsifying all but one of the figures in a 2017 stem cell paper.
Yesterday, Kyoto Universityannounced that the paper’s first author, Kohei Yamamizu, had fabricated and falsified datain the Stem Cell Reportspaper. According to the investigation report, none of the other authors were involved in the data manipulation.
Yamamizu works at the Center for iPS cell Research and Application (CiRA) at Kyoto University, directed by Shinya Yamanaka, a Nobel Prize winner for his pioneering work in stem cell biology.
A spokesperson for the journal told us that the authors disclosed the problems last week and Stem Cell Reports will be retracting the paper, published last February.
Brachycephaly describes a condition where the back of the head is abnormally flat and trichomegaly refers to extra length, curling, pigmentation, or thickness of the eyelashes.
Marc Pieterse, of the Netherlands, has a son with the rare RPS23 mutation, one of two known patients in the world. The mutation affects ribosomes, cell components involved in protein production. On Aug. 9, we reported on Pieterse’s crusade against OMIM’s original name for the condition, which dubbed it a syndrome. He has feared that calling it a syndrome would “stigmatize” his son’s condition and tried to get the paper underpinning the OMIM entry retracted. The American Journal of Human Genetics has said it will not retract the paper.
The father of a boy with a rare genetic mutation has accused a scientist of exploiting his child by proclaiming the defect a “genetic syndrome” and naming it after herself.
At an impasse with scientists investigating, publicizing, and interpreting his son’s condition, the father seems willing to use any leverage he can muster to remove the “syndrome” entry in an online genetic disease database. Based solely on an email he obtained from the database director, the father became convinced that if the paper underpinning the entry were retracted, the syndrome would go down with it. So earlier this year, he withdrew his consent and asked the journal that published the paper for a retraction, based on improper patient consent. He has also threatened to lob accusations of research misconduct at the paper’s last author.

A 2014 paper containing data manipulated by a former graduate student has finally been retracted, two years after the U.S. Office of Research Integrity (ORI) published its findings.
In August 2015, the ORI published a report that Peter Littlefield, who was working on his PhD at the University of California, San Francisco (UCSF), had committed “research misconduct by falsifying and/or fabricating data” in two papers. Littlefield agreed to correct or retract the papers–one published in Chemistry & Biology and the other in Science Signaling.
When we contacted Chemistry & Biology back in August 2015, a spokesperson for Cell Press told us the journal was figuring out “the best way to correct the scientific record.”
A scientist in Germany has lost two papers that were collectively cited more than 500 times, after an investigation at her former university found her guilty of scientific misconduct.
The probe into Tina Wenz by the University of Cologne in Germany, her former employer, recommended that six of her papers — which have induced some chatter on PubPeer — should be retracted. One of these papers was pulled by Cell Metabolism last year. Now, Cell Metabolism has pulled another of Wenz’s papers, and she has also lost another study published in the Proceedings of the National Academy of Sciences (PNAS), which was previously corrected.
There are a lot of accusations about research misconduct swirling around, and not every journal handles them the same. Recently, Cell Metabolism Scientific Editor Anne Granger and Cell Metabolism Editor-in-Chief Nikla Emambokus shared some details about their investigative procedure in “Weeding out the Bad Apples.” We talked to them about why they don’t necessarily trust accusations leveled on blogs (including ours), but will consider the concerns of anyone who approaches the journal directly – even anonymously.
Cell Press journals will not be retracting two papers that were flagged with expressions of concern (EOCs) in April after one author claimed to have manipulated some experiments.
In a strange turn of events, as we previously reported, the study’s corresponding author refuted the claims of the author who confessed to fraud, citing concerns about his “motives and credibility.” Since then, two independent labs repeated the authors’ experiments, and “largely confirm” the central conclusions of a Cell paper, but were inconclusive regarding a paper in Molecular Cell. Regardless, in both cases, the journals have decided to take no further action.
Both expressions of concern (and their associated editorial notes) will remain online, as part of the “permanent record,” a Cell Press spokesperson told us.
Researchers have retracted a 2016 cancer study, citing discrepancies between the data and images presented in the paper.
Although the retraction notice itself contains relatively little information, we’ve obtained a letter from the last author — Jun-Li Luo of The Scripps Research Institute in Jupiter, Florida — to the editor-in-chief of Cell Death and Differentiation that says a bit more.
According to the letter, after receiving the anonymous email, Luo conducted an investigation, contacting co-authors who contributed each of the figures in question. Although Luo writes that he has no reason to suspect fraud, the researchers were not able to provide some of the original data.
