Researchers pull Nature paper over first author’s objections

Researchers have retracted a 2015 Nature paper about the molecular underpinnings of immune function after discovering they could not replicate key parts of the results.

The first author, Wendy Huang — who started working as an assistant professor at the University of California, San Diego, only months after the paper appeared — did not sign the retraction letter, published last week. The research was conducted while Huang was working as a postdoctoral fellow at New York University, home of last author Dan Littman (also an investigator at the Howard Hughes Medical Institute).

What happened appears to be a case of “he said, she said:” Littman asked to retract the paper after his lab couldn’t reproduce it, and Huang insists the data remain correct, saying the process had been “unfair and done without due process:”

An author says his work should be “widely heralded and promoted.” So he published it 3 times.

Barislav Momčilović thinks that iodine status is — after iron deficiency — the “main public health” issue in the world today. So when he figured out what he believed was the best way to test levels of the mineral, he was determined to get the message out.

A little too determined, perhaps: He published the same information three times. And one journal caught on.  Last week, Thyroid retracted “Hair Iodine for Human Iodine Status Assessment,” a 2014 paper that they say overlapped with two earlier works.

While publishing duplicate work is considered by some to be just a violation of restrictive publisher copyright agreements, the presence of such duplicates in the literature can bias systematic reviews and other attempts to describe the state of the evidence in a given field. In a retraction notice, Thyroid noted that this was a case of Continue reading An author says his work should be “widely heralded and promoted.” So he published it 3 times.

After probe, journal removes flag from four papers, corrects manipulated images

Last year, Journal of Cell Science added notices to four papers after a reader contacted the editors with some concerns about issues with the figures. Now, it’s replacing the previous editorial notices with corrections, which address duplicated images and data.

When the journal issued expressions of concern for four papers co-authored by José Ignacio Rodriguez-Crespo about the allegations (which had also been raised on PubPeer), it notified his institution, the Universidad Complutense de Madrid (UCM). The newly issued correction notices explain that UCM investigated the four papers, and the data support the results and conclusions. In two cases, the authors supplied the original data, and in the others, they replicated the experiments.

Rodriguez-Crespo declined to comment, saying only that the journal

35,000 papers may need to be retracted for image doctoring, says new paper

Elisabeth Bik

Yes, you read that headline right.

In a new preprint posted to bioRxiv, image sleuths scanned hundreds of papers published over a seven-year period in Molecular and Cellular Biology (MCB), published by the American Society for Microbiology (ASM). The researchers — Arturo Casadevall of Johns Hopkins University, Elisabeth Bik of uBiome, Ferric Fang of the University of Washington (also on the board of directors of our parent non-profit organization), Roger Davis of the University of Massachusetts (and former MCB editor), and Amy Kullas, ASM’s publication ethics manager — found 59 potentially problematic papers, of which five were retracted. Extrapolating from these findings and those of another paper that scanned duplication rates, the researchers propose that tens of thousands of papers might need to be purged from the literature. That 35,000 figure is double the amount of retractions we’ve tallied so far in our database, which goes back to the 1970s. We spoke with the authors about their findings — and how to prevent bad images from getting published in the first place.

Retraction Watch: You found 59 potential instances of inappropriate duplication — how did you define this, and validate that the images were problematic?

University recommends researcher be fired after misconduct finding

Suchitra Sumitran-Holgersson

The University of Gothenburg has requested the dismissal of a researcher who has been found guilty of scientific misconduct in seven articles.

The researcher, Suchitra Sumitran-Holgersson, is “guilty of research misconduct through intentional fabrication, falsification or suppression of basic material and deliberately abandoning good scientific practice in seven of the reviewed articles,” according to a press release from the University of Gothenburg (GU). Sumitran-Holgersson continues to insist any issues were the result of “unfortunate errors,” not misconduct.

As a consequence, GU vice-chancellor Eva Wiberg has:

Karolinska finds Macchiarini, six other researchers guilty of misconduct

Paolo Macchiarini

Former super-star surgeon Paolo Macchiarini is guilty of misconduct, along with six of his co-authors — including one who initially help alert authorities to problems with Macchiarini’s work, according to an announcement today by his former institution, the Karolinska Institute.

KI is also calling to retract six articles co-authored by Macchiarini and his colleagues, including two highly cited papers in The Lancet. The papers described the procedure and outcomes of transplanting synthetic tracheas into three patients between 2011 and 2013.

KI’s investigation uncovered “serious inaccuracies and misleading information in the reviewed articles:”

A critic with more than two dozen retractions can’t seem to stop plagiarizing

A mysterious lit and film critic who built a significant portion of his career using the words of other scholars instead of writing his own appears to be attempting a second act.  

Last year, Richard-Lawrence Etienne Barnett, who has lost more than two dozen papers for plagiarism, published a book called “The Adversarial Text,” which appears to have a rather cozy relationship with four of his retracted articles. The apparent purloinment was first reported by Volker Schröder, a scholar of French and Italian at Princeton University who has been following the Barnett case for the better part of two decades.

In 2001, Schroeder found that

A journal decided to correct, rather than retract, a paper that contained “potentially contentious advice.” Do you agree with their call?

In March, a journal published a paper about blood sugar levels in newborns that caused an immediate outcry from outside experts, who were concerned it contained a sentence that could be potentially harmful if misinterpreted by doctors.

Recently, the journal explained — in impressive detail — why it’s not retracting the paper. That, of course, gives readers the ability to form their own opinions. After seeing the pros and cons, let us know if you think the journal made the right call in a poll at the bottom of the story.

When it first appeared, the paper — “Newborn plasma glucose concentration nadirs by gestational-age group,” published by Neonatology — included this sentence in its abstract:

In order to potentially prevent low glucose concentrations at the time of the nadir, exogenous glucose should be provided to all newborns as soon as possible after birth.

According to an editorial note published by the journal’s editors, that caused immediate concern for outside experts:

A misconduct probe — which led to 20 retraction requests — took four years. Why?

Santosh Katiyar

A probe into the work of a researcher who studied natural products for cancer had many stops and starts along the way — including five extensions granted by the U.S. Office of Research Integrity — according to documents obtained by Retraction Watch.

Following a public records request, we recently obtained a copy of the report on the investigation of allegations of misconduct by Santosh Katiyar, issued jointly by the University of Alabama Birmingham and the Birmingham VA Medical Center. As a result of the report, the institutions have requested 20 retractions of work by Santosh Katiyar, who received millions in funding from the U.S. National Institutes of Health. 

How does the report stack up?

Fecal transplant paper pulled for “personal issue”

Last month, the Journal of Pediatric Gastroenterology and Nutrition pulled an article on fecal transplantation for a reason that, well, doesn’t pass the sniff test.

The paper, by Sonia Michail of Children’s Hospital Los Angeles, appeared online in October 2017 and described a randomized controlled trial of fecal transplants to treat kids with ulcerative colitis. (If you’re interested, here’s an overview of how fecal transplantation works.) The trial, or one awfully like it, is listed on ClinicalTrials.gov, and shows Michail as the lone investigator on the study, which is aiming to gather more than 100 participants.

But the journal retracted the article — which was the subject of a laudatory editorial in the journal pointing readers to the findings — with an entirely opaque statement, saying that the work
