“I do wish that journal editors would not take six years to perform an investigation and to retract.”

Elisabeth Bik

In July 2014, Elisabeth Bik notified PLOS ONE that she’d found three papers in the journal by a group of researchers who had clearly manipulated figures in the articles. 

More than six years later, the journal has finally retracted the publications. 

The authors were affiliated with the Fourth Military Medical University in Shaanxi, China. The notice for 2013’s “Hyperthermia-induced NDRG2 upregulation inhibits the invasion of human hepatocellular carcinoma via suppressing ERK1/2 signaling pathway” refers to overlapping data in Figure 1A, similarities between data in Figure 1B and Figure 6C despite the fact that lanes “represent samples exposed to different experimental conditions,” and more:

Science retracts paper as authors blame pandemic for image issues

Science has retracted a paper it published in July by a group of authors in China over concerns about two images in the article — problems the researchers have attributed to chaos in their group due to the COVID-19 pandemic.

The paper, “Proton transport enabled by a field-induced metallic state in a semiconductor heterostructure,” was a collaboration by researchers from various institutions in the country, as well as one in the United Kingdom. The senior author was H.B. Song, of the University of Geosciences in Wuhan.

Shortly after publication, Fang Zhouz, a science sleuth in China, posted concerns about the article on his blog —  which drew the attention of Elisabeth Bik. Bik eventually amplified those concerns on PubPeer, where she noted that:

Author says ‘misguided efforts for the ideal western blot led to the withdrawal of these studies’

A figure marked up by Elisabeth Bik on PubPeer

The Journal of Biological Chemistry has retracted two papers by a group from the University of Toronto over what the leader of the research says were “misguided efforts” by a co-author to make the perfect Western blot. 

The retractions are among a batch of seven recent removals by the journal for image issues, some of which were flagged on PubPeer. 

Two of the papers, which date back to 2004, come from one group, two from another and two from a third. The seventh is a stand-alone for a group with a history of problematic articles.

Major heart journal retracts two papers from Oxford group for misconduct

The Journal of the American College of Cardiology (JACC) has retracted two 2018 papers out of the University of Oxford because of misconduct.

Both retraction notices blame first author Alexander Liu, a student in the lab at the time, who disputes the retractions. The studies were part of a larger effort to improve heart imaging that caught the attention of cardiologists and was highlighted by Oxford in 2015.

Here’s the notice for “Diagnosis of Microvascular Angina Using Cardiac Magnetic Resonance,” a paper that has been cited 59 times, according to Clarivate Analytics’ Web of Science, earning it a “highly cited paper” designation:

Did a journal retract your paper on homeopathy? Meet the journal that will publish your complaint

A homeopathy journal that Elsevier dropped in the wake of concerns about excessive self-citation appears to have carved out a new niche for itself: self-pity. 

In 2016, Homeopathy lost its slot on Thomson Reuters’s (now Clarivate’s)  influential journal rankings list after an analysis found that more than 70% of citations in the papers it published were of papers it published. That led Elsevier to cut the journal loose — although it remains in business under the umbrella of Thieme, and has since earned its impact factor back. (For more on why that’s important to journals, see this story.)

Part of Homeopathy’s mission under new ownership, it seems, is to criticize journals that have spurned its contributors. Well, one journal, anyway.

Authors retract highly cited 2014 Science paper

The authors of a 2014 paper in Science have retracted it, after becoming aware that impurities in the chemicals they used for their experiments may have generated the apparent findings.

The paper, “Ammonia synthesis by N2 and steam electrolysis in molten hydroxide suspensions of nanoscale Fe2O3,” has been cited 323 times, according to Clarivate Analytics’ Web of Science, earning it a “hot paper” designation. According to a summary of the work, “the protocol points to a way to produce ammonia from purely renewable resources.”

Here’s the retraction notice:

Author retracts Nature commentary over concerns about section’s sponsorship

Kenneth Witwer

Nature has retracted a recent commentary after the author complained that he had been misled by the relationship of the publication to a financial sponsor and told to avoid critiquing work from the institution. The journal says it is revisiting its “editorial guidelines and processes” in the wake of the case. 

Kenneth Witwer, an RNA expert at Johns Hopkins University in Baltimore, said he had been approached by Nature earlier this year to contribute a piece to one of the journal’s “Outlook” sections.  

Outlook sections are sponsored, and in this case, the supporter was Nanjing University in China. One of the institution’s deans and star researchers, Chen-Yu Zhang, had arranged the section and written an article for it as well — a piece Witwer described as essentially an advertorial for Zhang’s questionable research. [Springer Nature, in comments to Retraction Watch, said that “The Zhang piece is advertorial, is clearly labelled as such and uses a different typeface from editorial content to promote transparency.”]

According to Nature policy

A big Nature study on a tiny dinosaur is being retracted

A paper on a pocket-sized winged “dinosaur” is being retracted after new unpublished findings cast doubt on the authors’ characterizations of their discovery.

The study, “Hummingbird-sized dinosaur from the Cretaceous period of Myanmar,” was published in Nature on March 11, 2020. Many news outlets, including the New York Times, Newsweek and National Geographic, picked up on the findings. 

Then on March 18, Zhiheng Li of the Chinese Academy of Sciences, along with co-authors, posted a comment on bioRxiv about the study, casting doubt on whether the amber-encased specimen was in fact a dinosaur or avian species.

Nature updated the study with an expression of concern on May 29, which said:

“Consistently unsurprised”: Nigerian vaccine study with no Nigerian authors retracted

Last month, PLOS ONE published a paper reporting on a trial to improve the uptake of the measles vaccine in Nigeria. The researchers were affiliated with IDinsight, a San Francisco-based “global advisory, data analytics, and research organization that helps development leaders maximize their social impact.”

San Francisco is about 7,800 miles from Lagos, and the list of authors — Sam Brownstone, Alison Connor and Daniel Stein, a former economist at the World Bank — seemed suspiciously devoid of Nigerian names.  

That omission was even more strange given the title of the article: “Improving measles vaccine uptake rates in Nigeria: An RCT evaluating the impact of incentive sizes and reminder calls on vaccine uptake.” Almost immediately after publication, Ejemai Eboreime, a physician and public health worker, pointed out on Twitter the implausibility of the implied claim that no local scientists were involved in a randomized controlled trial covering nine clinics throughout the country — which he alleged also was a violation of local research ethics provisions.

Authors of study on race and police killings ask for its retraction, citing “continued misuse” in the media

The authors of a controversial paper on race and police shootings say they are retracting the article, which became a flashpoint in the debate over killings by police, and now amid protests following the murder of George Floyd.

[See an update on this post.]

The 2019 article in the Proceedings of the National Academy of Sciences (PNAS), titled “Officer characteristics and racial disparities in fatal officer-involved shootings,” found “no evidence of anti-Black or anti-Hispanic disparities across shootings, and White officers are not more likely to shoot minority civilians than non-White officers.” It has been cited 14 times, according to Clarivate Analytics’ Web of Science, earning it a “hot paper” designation.

Joseph Cesario, a researcher at Michigan State University, told Retraction Watch that he and David Johnson, of the University of Maryland, College Park and a co-author, have submitted a request for retraction to PNAS. In the request, they write:
