New tool looks for signs of image doctoring

Mary Walsh

One of the most common reasons for retractions is image manipulation. When searching for evidence of it, researchers often rely on what their eyes tell them. But what if screening tools could help? Last week, researchers described a new automated tool to screen images for duplication (reported by Nature News); with help from publishing giant Elsevier, another group at Harvard Medical School is developing a different approach. We spoke with creators Mary Walsh, Chief Scientific Investigator in the Office for Professional Standards and Integrity, and Daniel Wainstock, Associate Director of Research Integrity, about how the tool works, and why — unlike the other recently described automated tool — they want to make theirs freely available.

Retraction Watch: What prompted you to develop this tool?

Overlooked virus “generated a mess,” infected highly cited Cell, PNAS papers

When Alexander Harms arrived at the University of Copenhagen in August 2016, as a postdoc planning to study a type of antibiotic resistance in bacteria, he carried with him a warning from another lab who had recruited him:

People said, “If you go there, you have to deal with these weird articles that nobody believes.”

The papers in question had been published in the Proceedings of the National Academy of Sciences in 2011 and Cell in 2013. Led by Kenn Gerdes, Harms’s new lab director, the work laid out a complex chain of events that mapped out how an E. coli bacterium can go into a dormant state, called persistence, that allows it to survive while the rest of its colony is wiped out.

Despite some experts’ skepticism, each paper had been cited hundreds of times. And Harms told us:

I personally did believe in the published work. There had been papers from others that kind of attacked [the Gerdes lab’s theory], but that was not high-quality work.

But by November 2016, Harms figured out that the skeptics had been right.  Continue reading Overlooked virus “generated a mess,” infected highly cited Cell, PNAS papers

After “considerable intellectual agony,” journal retracts Wansink paper

Eduardo Franco

Ever since critics began raising concerns about high-profile food scientist Brian Wansink’s work, he’s had to issue a series of high-profile retractions — and now has his seventh (including one paper that was retracted twice, after the journal removed a revised version, along with 14 corrections). The latest notice — first reported by BuzzFeed —  is for a paper that was originally corrected by the journal Preventive Medicine earlier this month — and the correction notice was longer (1636 words) than the original, highly cited paper (1401 words). Following criticism by James Heathers about the highly cited study back in March 2017, the authors issued a series of changes, including explaining the children studied were preschoolers (3-5 years old), not preteens (8-11), as originally claimed. (They made that mistake once before, in another retracted paper.) But critics remained concerned. Yesterday, the journal retracted the paper. We spoke with editor Eduardo Franco of McGill University — who provided us with an advanced copy of an accompanying editorial, soon to be published — about the editorial processes behind the two notices, including the moment the journal knew the correction wouldn’t suffice.

Retraction Watch: You write that the initial decision to correct the paper came with “considerable intellectual agony.” Can you say why?

Caught Our Notice: Brian Wansink issues correction that’s longer than original paper

Title: Attractive names sustain increased vegetable intake in schools

What Caught Our Attention: One thing can be said for the corrections for Brian Wansink‘s papers — they aren’t short.  After James Heathers outlined some of his concerns about the highly cited study back in March, 2017, the journal has issued a correction, and it’s longer (1636 words) than the original, highly cited paper (1401 words). Some of the changes include explaining the children studied were preschoolers (3-5 years old), not preteens (8-11), as originally claimed. (It may be hard to imagine how the authors could make such a mistake, but they did it once before, in another retracted paper.) Even with all those words explaining the correction — we’re only including an excerpt of the entire notice below — some concerns still remain: Continue reading Caught Our Notice: Brian Wansink issues correction that’s longer than original paper

Study that said hate cuts 12 years off gay lives fails to replicate

A highly cited paper has received a major correction as a result of the ongoing battle over attitudes towards gay people, when a prominent — and polarizing — critic showed it could not be replicated.  

In December 2017, researchers led by Mark Hatzenbuehler of Columbia University corrected the paper, originally published in Social Science & Medicine in February 2014, which showed that gay people who live in areas where people were highly prejudiced against them had a significantly shorter life expectancy. The corrigendum came more than a year after a researcher who has testified against same-sex marriage was unable to replicate the original study.

“Structural stigma and all-cause mortality in sexual minority populations,” has been cited 102 times, according to Clarivate Analytics’ Web of Science, and attracted media coverage when it was published, from outlets such as Reuters and U.S. News & World Report.

Researcher at Japan stem cell institute falsified nearly all images in 2017 paper

Shinya Yamanaka

An investigation by Kyoto University in Japan has found a researcher guilty of falsifying all but one of the figures in a 2017 stem cell paper.

Yesterday, Kyoto University announced that the paper’s first author, Kohei Yamamizu, had fabricated and falsified data in the Stem Cell Reports paper. According to the investigation report, none of the other authors were involved in the data manipulation.

Yamamizu works at the Center for iPS cell Research and Application (CiRA) at Kyoto University, directed by Shinya Yamanaka, a Nobel Prize winner for his pioneering work in stem cell biology.

A spokesperson for the journal told us that the authors disclosed the problems last week and Stem Cell Reports will be retracting the paper, published last February.

In the university’s official statement, Yamanaka said: Continue reading Researcher at Japan stem cell institute falsified nearly all images in 2017 paper

Author under fire on PubPeer issues puzzling correction to chem paper

A researcher whose work has been heavily questioned on PubPeer has corrected a figure on a 2015 paper in Talanta — but the text of the correction doesn’t match the actual changes.

Recently, Rashmi Madhuri at the Indian Institute of Technology (Indian School of Mines) in Dhanbad corrected a 2015 paper about a diagnostic sensor that uses nanoparticles, noting that there was a “small error” in the legend describing figure 1. But the corrected image bears the same legend it had before, and instead swapped a panel of the figure that had been questioned on PubPeer.

Here’s another puzzling element to the story: Gary Christian at the University of Washington, one of the editors-in-chief of the journal, tells us he doesn’t “recall being aware of the corrigendum:”

“Devastated” researchers worry co-author’s use of fake reviews could hurt their careers

In late December, Ana Khajehnezhad learned what no scientist wants to hear: One of her papers had been retracted. The reason: Her co-author had faked the reviews.

Khajehnezhad, who works at the Plasma Physics Research Center at Islamic Azad University in Tehran, Iran, told Retraction Watch she was “devastated” to hear the news:

I was so shocked. … I had absolutely no knowledge whatsoever on the actions taken by the corresponding author.

As we reported last month, Elsevier is retracting 26 papers affected by fake reviews; Ahmad Salar Elahi is corresponding author on 24 of them, including Khajehnezhad’s now-retracted paper published in International Journal of Hydrogen Energy. Many of Ehali’s co-authors are now facing the consequences of these retractions. Three of them shared their story.

Accusations of ”false claims” in anti-global warming paper unresolved after three years

Three years after receiving a complaint about extensive plagiarism and major errors in an anti-global warming paper, Elsevier says it’s still reviewing the allegations.

In 2014, readers complained to the Elsevier journal Renewable and Sustainable Energy Reviews about plagiarism and technical flaws in a 2013 paper questioning mainstream climate change science.

When we first began reporting the story last year, a spokesperson for Elsevier told us:

After Elsevier knew an author faked reviews, it kept accepting his papers for more than a year

In March 2017, Christopher Blanford received an email from an editor at the Journal of Crystal Growth. Blanford had been named as a suggested reviewer for a manuscript, and the editor, Arnab Bhattacharya, wanted to verify that the Gmail account the authors provided was legitimate.

It was not.

Blanford—a senior lecturer in biomaterials at the University of Manchester, UK—thought it was an “amusing coincidence” that he was chosen as a fake reviewer, given that he has written about malpractice in academic publishing. He confirmed the Gmail account was not his, and the other two suggested reviewers told Bhattacharya, a professor at the Tata Institute of Fundamental Research in Mumbai, India, the same thing.
