University investigation finds misconduct by bone researcher with 23 retractions

Hirosaki University

As a bone researcher continues to accrue retractions, an investigation at his former university has found misconduct in more than a dozen papers.

On Nov. 15, Japan’s Hirosaki University announced it had identified fabrication and authorship issues in 13 papers by Yoshihiro Sato, and plagiarism in another.

Sato, a professor at Hirosaki University Medical School from 2000 to 2003, died in January. He was last affiliated with Mitate Hospital. Multiple retractions in recent months have pushed Sato higher up our leaderboard; by our count, he now has 23 retractions and the university said there are likely more to come.

”Definitely embarrassing:” Nobel Laureate retracts non-reproducible paper in Nature journal

A Nobel Laureate has retracted a 2016 paper in Nature Chemistry that explored the origins of life on earth, after discovering the main conclusions were not correct.  

Some researchers who study the origins of life on Earth have hypothesized that RNA evolved before DNA or proteins.  If true, RNA would have needed a way to replicate without enzymes. The Nature Chemistry paper found that a certain type of peptide — which may have existed in our early history — made it possible for RNA to copy itself.

Jack W. Szostak—a professor of chemistry and chemical biology at Harvard University in Cambridge, Mass., who shared the 2009 Nobel Prize in Physiology or Medicine with Elizabeth Blackburn and Carol Greider for their pioneering research on aging—told us he was “incredibly excited” when he “thought we had at least a partial solution to this problem,” which researchers have been working on for over 50 years.  

But in subsequent experiments, Tivoli Olsen — a member of Szostak’s lab — could not reproduce the 2016 findings. When she reviewed the experiments from the Nature Chemistry paper, she found that the team had misinterpreted the initial data: The peptide in question did not appear to provide an environment that fostered RNA replication.

The errors were “definitely embarrassing,” Szostak told us: Continue reading ”Definitely embarrassing:” Nobel Laureate retracts non-reproducible paper in Nature journal

When publishers mess up, why do authors pay the price?

Springer has retracted two papers, which appeared online earlier this year in different journals, after discovering both were published by mistake.

A spokesperson at Springer explained that the retractions are “due to a human error.”

According to one of the retraction notices, published in Archive for Mathematical Logic, the paper had not yet undergone peer review and the author plans to resubmit his paper to the journal. The other retraction notice, published in Arabian Journal of Geosciences, simply states that an “error in the submission system” is to blame. Unfortunately, in both cases the authors now have a retraction on their record, seemingly through no fault of their own.

Neither notice indicates what publisher glitches led to the premature publications. We asked the spokesperson for clarity, but she did not elaborate. When asked whether Springer has made changes to prevent these errors from happening again, the spokesperson said:

Caught Our Notice: What if you find out a paper relied on expired herbal supplement?

Title: Exploration of inhibitory mechanisms of curcumin in lung cancer metastasis using a miRNA- transcription factor-target gene network

What Caught Our Attention: The researchers were studying how curcumin, a component of the spice turmeric, can inhibit lung cancer metastases. But upon learning that the primary material had been expired at the time of testing (and realizing they were unable to repeat their experiments), the researchers pulled their paper. Expiration dates do have safety factors built in, but attention to such details is imperative in research.  Continue reading Caught Our Notice: What if you find out a paper relied on expired herbal supplement?

Journal bans author for three years after retracting paper with “serious ethical” problems

An anatomy journal has banned a researcher from submitting papers for three years after determining one of his recently published papers suffered from “serious ethical” issues.

According to Jae Seung Kang, associate editor at the journal Anatomy and Cell Biology (ACB), the paper’s sole author—Jae Chul Lee—falsified both his affiliation and approval for conducting animal experiments in the paper, published online in March.

Kang said the journal discovered the issues after Lee submitted other papers to the journal this past August. During the journal’s review process, it discovered “over 70% redundancy”—ie, plagiarism—between the newly submitted papers and two now-retracted papers—the ACB paper as well as a 2015 paper published in the Journal of Pathology and Translational Medicine, on which Jae Chul Lee was corresponding author. The issues prompted the journal to conduct “an in-depth investigation,” Kang said. Continue reading Journal bans author for three years after retracting paper with “serious ethical” problems

Weekend reads: Problems in studies of gender; when scholarship is a crime; a journal about Mark Zuckerberg photos

The week at Retraction Watch featured a call to make peer reviews public, lots of news about Cornell food researcher Brian Wansink, and a request by the U.S. NIH that the researchers it funds don’t publish in bad journals. Here’s what was happening elsewhere: Continue reading Weekend reads: Problems in studies of gender; when scholarship is a crime; a journal about Mark Zuckerberg photos

Caught Our Notice: Don’t count your chicken (genes) before they’re hatched

Title: Molecular Characterization and Biological Activity of Interferon-α in Indian Peafowl (Pavo cristatus)

What Caught Our Attention: Soon after the paper appeared, the journal was alerted to the fact its findings were at odds with others in the field. When the editor approached the authors, everything fell apart: The authors couldn’t repeat the experiments, and “were also unsure of the molecular probes that were used in the study.” While it isn’t unusual to have doubts about data — since since research is a process of experimentation — it is odd not to know how your experiment was conducted. The paper was retracted less than two months after it was published. The manuscript was accepted two months after it was submitted in early May, theoretically giving reviewers enough time to catch these issues (along with the authors’ failure to cite relevant papers).

NIH to researchers: Don’t publish in bad journals, please

The U.S. National Institutes of Health has noticed something: More of the research it’s funding is ending up in questionable journals. Recently, the agency issued a statement highlighting some qualities of these journals — aggressively soliciting submissions, failing to provide clear information about pricing — and urging researchers to avoid them. The NIH’s goal: to “help protect the credibility of papers arising from its research investment.” We asked the NIH for more information about the guide notice; a representative returned responses, asking that we attribute them to the NIH Office of Extramural Research.

Retraction Watch: What prompted the NIH to issue this guide notice? Was there an incident?

Scientist to chemistry journal: “Plse retract this ms ASAP”

The presence of allegedly obvious manipulations in a 2017 chemistry paper has prompted a reader outcry.

Over the last couple of days, a user on PubPeer and others on Twitter have accused the paper of containing clear duplications; the paper was already corrected in August, in which one scientist alleges the authors replaced “an obviously fabricated” figure with a “slightly better photo-shopped one.”

In response, the editor of ACS Biomaterials Science & Engineering, David Kaplan, told us:

Brazil research foundation sues scientist over $103k scholarship

The São Paulo Research Foundation (FAPESP), a state-level agency in Brazil that funds scientific research, is suing Paty Karoll Picardi, a protégé of Brazilian diabetes researcher Mario Saad.

According to a São Paulo Court of Justice website, the reason stated is for “recebimento of bolsa de estudos,“ which translates to “receipt of scholarship.” FAPESP is suing for 334,116 Brazilian Reals ($102,927).

Now, Picardi is counter-suing, according to a case document released Nov. 17 — although we’re not sure for what, and why.  Continue reading Brazil research foundation sues scientist over $103k scholarship
