“The most horrific time of my career.” What do you do when you realize years of your published work is built on an error?

In September 2019 Nicola Smith, a molecular pharmacologist in Australia, faced a brutal decision. She’d realized that she’d made a mistake — or rather, failed to catch a mistake in her group’s research before the crippling error was published — in two academic articles which were the culmination of years of work. And she could either tell the world, or pretend it never happened.

Her students had been having trouble reproducing lab data. Once she looked into it and she figured out why, she told them, “Guys, you’re not going to believe this.” A cloning error had ensured the experiments were doomed to fail from the start.

If she came clean, she knew that at least one of the articles would most likely be retracted and she’d have to live with a lasting mark on her and her team’s record. “What can I do to minimize the impact” on her two students? Smith thought at the time.

In particular, Tony Ngo,who was first author on both papers and had recently finished a PhD in her lab, was looking forward to a future in academia. Smith was terrified of tarnishing his prospects.

What was to stop her from just keeping quiet about it?

Researcher at Tehran medical school loses three papers because “overlap without cross-referencing is not legitimated”

A pharmacy researcher at Tehran University of Medical Sciences has had three papers retracted, and one corrected, because he duplicated his other articles.

Hamid Akbari Javar is the common author on all four papers, which appear in the African Journal of Pharmacy and Pharmacology, the International Journal of Pharmaceutical Sciences and Research, the Indian Journal of Pharmaceutical Sciences, and the International Journal of Molecular Medicine.

Narges Shokri, of the School of Pharmacy of Ardabil University of Medical Sciences, also in Iran, is an author of the three retracted papers, but not the corrected paper in the International Journal of Molecular Medicine.

Here’s the notice for “Comparison of Calcium Phosphate and Zinc Oxide Nanoparticles as Dermal Penetration Enhancers for Albumin,” in the Indian Journal of Pharmaceutical Sciences:

Western University materials scientist committed misconduct, according to investigation

An investigation into the work of a researcher at Western University “resulted in a clear determination of research misconduct,” according to a retraction notice, but details are scant.

Here’s the notice for “Synthetic peptides derived from salivary proteins and the control of surface charge densities of dental surfaces improve the inhibition of dental calculus formation,” published in Materials Science and Engineering: C in 2017 by Bernd Grohe:

Stem cell researchers lose two more papers, making three

A Hindawi journal has retracted two 2013 papers by a group of stem cell researchers in China over issues with the images in the articles, bringing their count to three.

Here’s the notice for “Side-by-Side comparison of the biological characteristics of human umbilical cord and adipose tissue-derived mesenchymal stem cells,” by Lili Chen and colleagues from Huazhong University of Science and Technology in Wuhan:

Authors retract Nature paper after realizing some data were “calculated wrongly”

A group of authors at Nagoya University and Kyoto University have retracted a 2019 Nature paper because of errors.

Here’s the retraction notice:

Stem cell researcher’s retraction count may near two dozen

A stem cell researcher in Japan could end up with 23 retractions after officials at his former institution confirmed that he’d committed research misconduct in nearly two dozen papers.

According to a report released last week by Aichi Gakuin University, Nobuaki Ozeki misused images, fabricated data and recycled text in 20 papers. Ozeki has had 19 papers retracted to date, 17 of which are described in the analysis. The latest report — an offshoot of one in 2018 that found he had committed misconduct in three papers — expands Ozeki’s liability to 22 articles.

Ozeki has roughly 40 indexed journal articles on his CV, however, and journals may decide to conduct their own investigations into his work. Articles in the International Journal of Medical Sciences, Differentiation, and the Journal of Endodontics were named in the report but so far remain intact.

Psychologist’s paper retracted after Dutch national body affirms misconduct findings

A cognitive psychologist in Germany has lost one of two papers slated for retraction after her former institution found her guilty of misconduct.

In a 2019 report, Leiden University found that Lorenza Colzato, now of TU Dresden, had failed to obtain ethics ethics approval for some of her studies, manipulated her data and fabricated results in grant applications. Although the institution did not identify Colzato by name, Retraction Watch confirmed her identity.

The Leiden report — the conclusions of which were affirmed by the Netherlands Board on Research Integrity last month — called for the retraction of two papers by Colzato and her co-authors, three of whom acted as whistleblowers in the case. As the trio told us in an interview last December:

Two and a half years after findings of misconduct, stem cell researchers up to 19 retractions

A group of researchers at Aichi Gakuin University in Nagoya, Japan, continues to lose papers for duplication of images and text from their previous work, and is now up to 19 retractions.

Please see an update on this post.

Here’s a typical notice, for “Bone morphogenetic protein-induced cell differentiation involves Atg7 and Wnt16 sequentially in human stem cell-derived osteoblastic cells,” a paper published in 2016 in Experimental Cell Research, an Elsevier title:

Researcher leaves post at Australian university years after papers come under scrutiny

Three years after work from his lab was the subject of “serious allegations,” a professor at Deakin University in Australia has left his post, Retraction Watch has learned.

In an October 6, 2020 letter to staff at Deakin’s School of Medicine obtained by Retraction Watch, Dean Gary Rogers writes that Jagat Kanwar, who joined the school’s faculty in 2006, would be leaving effective October 16. Rogers continues:

Authors earn praise — but a “poorly worded” retraction notice — for flagging their errors

The authors of an October 2020 paper on the genetics of thyroid cancer are getting praise from the journal for retracting their article after learning that it contained a critical error.

The paper, “Mendelian randomization supports a causative effect of TSH on thyroid carcinoma,” had appeared in Endocrine-Related Cancer, a bioscientifica property.

Jonathan Fussey, a surgeon at Royal Devon and Exeter Hospital, and the first author of the study, told us:
