Journals punished by high-profile indexing service cry foul, demand a recount

A group of editors of journals focused on the history of economics has gone public to urge Clarivate Analytics, which publishes a highly influential ranking of journals, to reconsider its decision to drop the titles from this year’s index.

Clarivate said it suppressed the titles because of apparent “citation stacking,” in which various editors agree to cite one another to boost their journals’ Impact Factors (JIFs). The metric is based on average rates of citation over a given period. As we noted in a June 26 post about the suppressions, suppressing titles Continue reading Journals punished by high-profile indexing service cry foul, demand a recount

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:”

A university went to great lengths to block the release of information about a trial gone wrong. A reporter fought them and revealed the truth.

Jodi S. Cohen

Here’s a story that shows the lengths a public university — The University of Illinois at Chicago — went to block the release of information about a child psychiatry trial gone wrong, and how a reporter — Jodi S. Cohen of ProPublica — fought them effectively at every turn to reveal the truth.

Earlier this year, ProPublica “revealed that the National Institute of Mental Health ordered the university to repay $3.1 million in grant money it had received to fund [Mani] Pavuluri’s study.” This kind of clawback is very, very rare.

We tipped our hats to Cohen then, because we had been trying for years to obtain documents that would tell the full story of the Pavuluri case, which we had been covering since 2015 when a retraction appeared. In particular, we’ve been trying to get the university to release their report of the investigation into Pavuluri’s work. We have been making a push for such reports, as we noted earlier this week in a roundup of more than 16 of them.

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

Journal holds firm on decision not to retract Macchiarini paper, despite outside pressure

Earlier this year, the president of the Karolinska Institute, Ole Petter Ottersen, contacted the journal Respiration, saying KI had conducted an investigation and determined that a 2015 paper co-authored by once-lauded surgeon Paolo Macchiarini had been tainted by misconduct. Please retract the paper, Ottersen said. When the journal said no — opting to publish correspondence from KI and the authors’ response instead — Ottersen posted some of their correspondence online, in an attempt to pressure the journal to do the right thing. It’s not going to work, according to Thomas H. Nold, publication manager at Karger, which publishes Respiration. We spoke to Nold about the journal’s plans for the paper.

Two years of stonewalling: What happened when a scientist filed a public records request for NASA code

Nathan Myhrvold

Retraction Watch readers may know Nathan Myhrvold, who holds a PhD in physics, as the former chief technology officer at Microsoft, or as the author of Modernist Cuisine. They may also recall that he questioned a pair of papers in Nature about dinosaurs. In that vein, he has also been raising concerns about papers describing the sizes of asteroids. (Not everyone shares those concerns; the authors of the original papers don’t, and astronomer Phil Plait said Myrhvold was wrong in 2016.) Last month, Myhrvold published a peer-reviewed paper as part of his critique. The final version of that paper went live today, as did a story about the science in The New York Times and a detailed explanation by Myrhvold in Medium. As the discussion over the results continues, here he shares his experience trying to obtain details about the methodology the authors used.

Two years ago, I uploaded a preprint to arXiv.org describing what I considered serious problems, including apparently irreproducible results, that I had uncovered when analyzing a set of research articles published by the NASA Jet Propulsion Laboratory (JPL) NEOWISE project. NEOWISE is the largest scientific analysis of asteroids ever conducted; the researchers on the project have so far published estimated sizes of more than 164,000 objects in the solar system, estimates they have claimed were all derived by applying a standard approach to raw observations from the WISE space telescope.

My findings generated quite a stir in the media, including stories in The New York Times, Science, and Scientific American, among other outlets. My hope and expectation was that shining light on these troubling issues would spur the JPL researchers to retract or correct their papers. At the very least, I thought, they would release the various unpublished techniques that they had used in a series of highly cited papers, stretching from 2011 to 2015, thus lifting the veil of secrecy that had prevented me and other astronomers from replicating their results.

Does the Mediterranean diet prevent heart attacks? NEJM retracts (and replaces) high-profile paper

The New England Journal of Medicine has retracted a 2013 paper that provided some proof that the Mediterranean diet can directly prevent heart attacks, stroke, and other cardiovascular problems.

The original paper, “Primary Prevention of Cardiovascular Disease with a Mediterranean Diet,” has been cited 1,759 times, according to Clarivate Analytics’ Web of Science.

But the findings haven’t disappeared — the authors have replaced the paper with a new version, which softens its earlier claims. Continue reading Does the Mediterranean diet prevent heart attacks? NEJM retracts (and replaces) high-profile paper

Journals flag two papers by prominent researcher — who is also on trial for domestic abuse

Adeel Safdar was once a rising star in the field of kinesiology. After completing his doctorate degree at McMaster University in Canada, working with one of the titans of his field, Safdar took a postdoc at Harvard, then accepted a newly created chair position at another university in Ontario.

That all came crashing down last year, when Safdar went on trial in Canada, accused of horrifically abusing his wife. Over the course of the trial, allegations arose about his research, prompting two journals to flag papers he co-authored with his former mentor, Mark Tarnopolsky.

Tarnopolsky — author of more than 400 papers, which have collectively been cited more than 17,000 times, according to Clarivate Analytics’ Web of Science — told Retraction Watch:

Karolinska told a journal to retract a paper by Macchiarini. It refused. The story didn’t end there.

The president of the Karolinska Institutet (KI) is frustrated.

At the beginning of the year, Ole Petter Ottersen informed a journal that one of its papers — co-authored by former superstar Paolo Macchiarini — had been tainted by misconduct. But the journal declined to retract it.

Despite the fact that KI had conducted its own investigation into the integrity of the paper, the journal Respiration argued that it was “not in a position to make a judgement on whether or not to retract this article.” Instead, it proposed publishing KI’s argument for why the paper should be retracted, along with a rebuttal from the authors.

To Ottersen, this is just wrong. Yesterday, he posted some of his correspondence with the journal, which includes his request for retraction, the journal’s response, and his rebuttal. Ottersen’s blog post concludes:
