Tracking retractions as a window into the scientific process

Authors use same images in two studies — one is retracted, the other flagged by journal

without comments

After researchers in China included the same images in two papers published online one month apart, one paper has been retracted, and the other flagged with an expression of concern. 

According to the retraction notice in the International Journal of Molecular Medicine (IJMM), the authors intended that the two different papers offered “different research perspectives.”

Meanwhile, the Chinese Medical Journal — which published the same images one month later — has issued an expression of concern (EOC), noting it “should not be considered as a statement regarding the validity of the work.” Both papers describe how cells regulate blood flow to the retina.

Normally, journals choose to retract the most recent paper containing duplicated images, but in this case, the IJMM paper was published online in February 2016, and the Chinese Medical Journal in March.

Journal cleans the house by retracting 6 cancer papers for plagiarism

with 3 comments

Following an investigation, a genetics journal has pulled six cancer papers published this year for plagiarizing from other sources.

According to an excerpt from the retraction notice in Genetics and Molecular Research, the journal has “strong reason to believe that the peer review process was [a] failure,” and has alerted the authors’ institutions.

The notice announcing the retraction of all six papers begins: Read the rest of this entry »

Journal issues three notices for plant biologist, two citing manipulation

without comments

Researchers have retracted a paper from a plant journal after a probe found problems with several figures.

According to the new retraction notice in The Plant Cell, some figures in the paper were manipulated, as well as “inappropriately duplicated and reused from a previous publication.” The authors assert that they believe the conclusions remain valid.

The journal has also issued two corrections that include some of the same authors — including one that cites inappropriate image manipulation.

Oops: Supposedly untreated cancer patients had surgery, after all

with one comment

gmrThe first author of a 2016 paper has retracted it after realizing that all the lung cancer patients that were supposed to have been untreated did, in fact, have surgery to remove their tumors. 

Zhao Kai, the study’s first author from the Qilu Hospital of Shandong University and Zibo Central Hospital (both in China), took full responsibility for the error.

Journal pulls cancer paper that used others’ data; authors MIA

without comments

A journal has retracted a paper after a reader pointed out some of the data looked familiar — and the authors never responded to the allegations.

According to the retraction notice in the International Journal of Molecular Medicine, the reader showed the journal that the histological data in two of the figures were from another published paper by different researchers. But when the journal contacted the authors on several occasions, they didn’t hear back.

Entomology journal retracts 2016 study with flawed analyses

with one comment

journal-of-medical-entomologyAn entomology journal has issued its first retraction during the current editor’s nearly 30-year tenure — for a 2016 study with serious flaws in the analyses. 

After the Journal of Medical Entomology (JME) published the study — about the identification of genes that enable an insect to detect odors — an outside researcher wrote a letter to the journal highlighting flaws in the paper. The journal then asked the authors to respond, and enlisted two additional peer reviewers to look into the study, the outside comment, and the authors’ response. They concluded the paper should be retracted.

William Reisen — the journal’s editor-in-chief from the University of California, Davis — said the journal believes the errors were unintentional and there was no fraud on the authors’ part. He added: Read the rest of this entry »

A first for us: Journal retracts obituary (but not for the reasons you think)

with one comment

journalofdigestivediseasesOn December 31st 2014, a pioneer in the study of inflammatory bowel disease passed away. An obituary published in the Journal of Digestive Diseases shortly thereafter is typical enough: It describes his achievements, importance to his patients, and battle with pancreatic cancer.

But “Loss in the Last Day of 2014: a Eulogy for Prof. Bing Xia” has now been retracted.

This is the first time we’ve seen an obituary pulled from a journal. Unfortunately, this was not a case of a premature obituary (which happens more often than you’d think)– the researcher did actually die, but it appears the journal published the obituary in the wrong place.

The retraction notice, published earlier this year, explains:

Controversial gene-editing study flagged by Nature journal

with 2 comments

nature-biotechnologyNature Biotechnology has issued an editorial expression of concern (EOC) for a widely criticized study describing a potentially invaluable new lab tool.

The EOC mentions the lack of reproducibility of the gene-editing technique, known as NgAgo. Alongside it, the journal has published a correspondence which includes data from three separate research groups that cast doubt on the original findings.

According to a spokesperson for the journal, some of the paper’s authors have objected to the decision to issue an EOC.

Earlier this month, we reported on a letter signed by 20 researchers which also raised concerns about the genome-editing activities of NgAgo — and alleged the lab that produced the initial results turned away investigators when they attempted to validate the tool in mammalian cells.

Here’s the EOC, published yesterday: Read the rest of this entry »

More questions arise over gene-editing tool

with 3 comments

13238A new letter signed by 20 researchers is casting additional doubts on the validity of a potentially invaluable lab tool — and alleges the lab that produced the initial results turned them away when they tried to replicate its findings in mammalian cells.

In a letter published this week in Protein & Cell, the researchers add their voices to the critics of the gene-editing technique, first described earlier this year in Nature Biotechnology.

The researchers outline their attempts to apply the technique — known as NgAgo — to a variety of cell types, which fell short:

Medical journal retracts study over fake review, authorship concerns

with 2 comments

european-journal-of-medical-researchA journal has retracted a 2015 study about lung cancer after learning the peer-review process had been compromised.

The paper was published in March, 2015 — the same month publisher BioMed Central (BMC) pulled 43 papers for fake reviews.

According to the retraction notice in the European Journal of Medical Research, the authors’ institution in China informed the publisher that the authors had used a third party to help with copyediting and submission to the journal, raising concerns about the authorship of the paper.

Here’s the retraction notice, published in August: Read the rest of this entry »
