Researchers at Columbia University have retracted a 2013 paper in The Journal of Clinical Investigation, after uncovering abnormalities in the stem cell lines that undermined the conclusions in the paper.
Last year, corresponding author Dieter Egli discovered he could not reproduce key data in the 2013 paper because almost all the cell lines first author Haiqing Hua used contained abnormalities, casting doubt on the overall findings. When Egli reached out to Hua for answers, Hua could not explain the abnormalities. As a result, Hua and Egli agreed the paper should be retracted.
Since some of the details of how the paper ended up relying on abnormal cells remain unclear, the university confirmed to us that it is investigating the matter.

When a group of authors decided to write up a curious case of a 35-year-old woman with a mysterious mass that took 11 years to be diagnosed, they tried repeatedly to contact the patient for her permission. When they couldn’t reach her, they published the paper anyway, removing any identifiable information.
But the report apparently included enough details for the patient to recognize herself — and when she read the paper, she asked the authors to retract it.
That’s the story according to the publisher of the 2016 case study, which recently retracted it with this notice:
Only days after his paper was published online, a neuroscientist has posted a comment on PubMed alerting readers to several duplication errors.
Despite the issues, which the researcher says were introduced into the final manuscript after peer review, he reassured readers that they do not influence the final conclusions in the paper.
On February 9, ten days after the article came online, corresponding author Garret Stuber at the University of North Carolina at Chapel Hill wrote a detailed comment on PubMed Commons, explaining that the “research community” had brought four figure-related errors to his attention. After investigating the concerns, Stuber discovered that the problems emerged after the peer-review process, “while revising the manuscript to comply with Nature Neuroscience’s final formatting guidelines.” In his note, he outlined the specific duplication issues that arose, which he says he plans to detail to the journal in a formal corrigendum letter.
Last week, we wrote about a somewhat remarkable retraction, of a 15-year-old paper by a current Illinois senator who used to be a mathematician. At the time, we were a bit perplexed by the language of the notice, which the senator — who helpfully took our call — couldn’t answer, since he wasn’t involved in drafting the notice.
We’ve since heard back from the journal that retracted the paper, which explained that their phrase that “most results are false” meant the findings by state senator Daniel Biss were inaccurate — not fraudulent.
Here’s more explanation from a joint statement sent to us by Jan van Mill and Jerry Vaughan, the editors in chief of Topology and its Applications:
A researcher in Switzerland has retracted her 2015 paper in the Journal of Cell Biology, saying the first author — her former postdoc — admitted to fabricating multiple aspects of the paper.
After Sophie Martin of the University of Lausanne couldn’t reproduce the data from another manuscript she was preparing to submit, she contacted her former student, Pranav Ullal, who admitted he had fabricated the data, along with two figures in the JCB paper.
A spokesperson for the University of Lausanne told us that Ullal left Switzerland after his contract was over, and is now in India.
Martin told us the whole experience has been upsetting:
Although it’s the right thing to do, it’s never easy to admit error — particularly when you’re an extremely high-profile scientist whose work is being dissected publicly. So while it’s not a retraction, we thought this was worth noting: A Nobel Prize-winning researcher has admitted on a blog that he relied on weak studies in a chapter of his bestselling book.
The blog — by Ulrich Schimmack, Moritz Heene, and Kamini Kesavan — critiqued the citations included in a book by Daniel Kahneman, a psychologist whose research has illuminated our understanding of how humans form judgments and make decisions and earned him half of the 2002 Nobel Prize in Economics.
Neurology has partially retracted a 2016 paper, replacing a figure and removing the author who contributed it after he was found guilty of misconduct.
The journal has replaced the figure with a new one that confirmed the findings of the original, and swapped the name of Andrew Cullinane with the scientist who constructed the new figure using a new dataset. Last year, the U.S. Office of Research Integrity declared that Cullinane had falsified data in this paper and one other while working as a postdoctoral fellow in the Medical Genetics Branch at the National Human Genome Research Institute (NHGRI).
Cullinane appears to be at Howard University in Washington D.C., according to his LinkedIn page. He is listed as an assistant professor in the Basic Sciences/Anatomy department of the university’s College of Medicine.
Here’s the partial retraction notice from the journal:
A cancer biologist based at the University of Maryland is transitioning out of research, as a journal has retracted three more of his papers.
Anil Jaiswal has now lost 13 papers, including, as we reported on February 6, six retractions issued earlier this month.
The Baltimore Sun reported this week that Jaiswal would no longer be conducting research at the University of Maryland School of Medicine, which we confirmed from a spokesperson:
It’s been a busy few months for Brian Wansink, a prominent food researcher at Cornell University. A blog post he wrote in November prompted a huge backlash from readers who accused him of using problematic research methods to produce questionable data, and a group of researchers suggested four of his papers contained 150 inconsistencies. The scientist has since announced he’s asked a non-author to reanalyze the data — a researcher in his own lab. Meanwhile, criticisms continue to mount. We spoke with Wansink about the backlash, and how he hopes to answer his critics’ questions.

A psychoanalyst has retracted an award-winning 2016 paper over concerns that it contained “sensitive” patient information.
On July 15, Judith L. Mitrani, a psychoanalyst based in California, published an article that included “sensitive clinical material” about a patient. Although we do not know what prompted the concerns, on November 21, Mitrani, in agreement with the journal’s editor-in-chief and publisher, retracted the article. The author and editor told us the retraction was meant to prevent non-experts from accessing the paper and to stop other non-Wiley sites from posting it.
The article was published after it had won the journal’s essay contest in 2015.
Here’s the retraction notice for “On Separating One from the Other: Images of a Developing Self,” published in the British Journal of Psychotherapy (BJP):
