Why “good PhD students are worth gold!” A grad student finds an error

Researchers in the Netherlands have retracted and replaced a 2015 paper on attention after discovering a coding error that reversed their finding.

Initially titled “Effects of Transcranial Direct Current Stimulation over Left Dorsolateral pFC on the Attentional Blink Depend on Individual Baseline Performance,” the paper appeared in the Journal of Clinical Neuroscience and was written by Heleen A. Slagter, an associate professor of psychology at VU University in Amsterdam, and Raquel E. London, who is currently a post-doc at Ghent University. It has been cited 19 times, according to Clarivate Analytics’ Web of Science.

But while trying to replicate the findings, Slagter and a then-PhD student of hers, Leon Reteig, found a critical mistake in a statistical method first proposed in a 1986 paper. Slagter told us:

Mathematician ranked as Clarivate “highly cited researcher” has third paper retracted

A math professor named as a “highly cited researcher” by Clarivate Analytics has had his third paper retracted after issues with it were flagged last year.

The mathematician, Abdon Atangana, is a professor at The University of the Free State, in Bloemfontein, South Africa, and China Medical University, Taiwan.

Atangana’s article, “Derivative with two fractional orders: A new avenue of investigation toward revolution in fractional calculus,” was published in The European Physical Journal Plus — where Atangana is an editor — on Oct. 24, 2016, and has been cited 37 times, according to Clarivate Analytics’ Web of Science.

Researcher to overtake Diederik Stapel on the Retraction Watch Leaderboard, with 61

A construction researcher is watching his publishing edifice crumble, as more upcoming retractions of his papers will bring his total to 61.

Ali Nazari is believed to be a member of a ring of authors whom a whistleblower has claimed are churning out unreliable research — hundreds of papers, according to the sleuth, who goes by the pseudonym Artemisia Stricta. Nazari lost his job at Swinburne University, in Australia, following a misconduct investigation in 2019.

According to the whistleblower (who laid out the case in a recent email to a journal editor):

What is a figure about budgies doing in four different plant papers?

As Antonella Longo was peer-reviewing a study for the journal Plant and Soil, she became “alarmed by one figure.” The figure’s title — ”Level2 GO terms of Melopsittacus_undulates” — seemed to be a misspelled reference to a bird species called Melopsittacus undulatus.

More commonly known as a budgie or parakeet, undulatus is a vibrantly colored parrot found in scattered parts of Australia. So what was a figure about a bird doing in a study about plants?

Concerned, Longo, of the BioDiscovery Institute at the University of North Texas, searched the internet for words used in the figure, “GO terms of Melopsittacus undulates.” She identified at least three additional studies that contained an image similar to the one in the study she was peer-reviewing, each with an identical title and color scheme, but with varying data. None of the studies are about birds.

Publisher retracting 68 articles suspected of being paper mill products

It appears to be Paper Mill Sweeps Week here at Retraction Watch.

On Tuesday, we reported on an editor who believes one such operation was responsible for the withdrawals of at least two articles in her journal.

Now, the Royal Society of Chemistry is retracting 68 articles, across three of its titles, after an investigation turned up evidence of what it suspects was the “systemic production of falsified research.” The society said it is in the process of beefing up its safeguards against milled papers and plans to train its editors to have “extra vigilance in the face of emerging, sophisticated digital fraud.”

Exercise science grad student at Australian university dismissed after he admitted faking data, says supervisor

A physiology journal has retracted a pair of papers from a group in Australia after learning that the flawed work was the subject of an institutional investigation.

The articles, both of which were published last year in The Journal of Strength and Conditioning Research, came from a group at the Murdoch Applied Sports Science Laboratory, part of Murdoch University. The first author on both papers was Liam J. Hughes, a PhD student at Murdoch who was terminated as a result of the misconduct.

“Confrontation is an important element of physics progress:” Paper on black holes retracted

A Springer Nature journal has retracted a 2019 article by a Slovenian physicist who claims that both Creationism and Big Bang theory are wrong, and that black holes are the engines driving the universe.

The paper, in Scientific Reports, was titled “Mass-energy equivalence extension onto a superfluid quantum vacuum,” and was written by Amrit Srečko Šorli. It has yet to be cited, according to Clarivate Analytics’ Web of Science, and four posts by Šorli’s institute that refer to it have been removed by Medium because the institute’s “account is under investigation or was found in violation of the Medium Rules.”

In 2010, Šorli founded the Bijective Physics Institute, whose proponents — we’re not sure how many there are beyond him and a few others named on the site — believe:

Holy cow: “The article as written contains misleading information and omits important details.”

An agriculture journal has put the “retraction” brand on a 2020 study about calving cattle after the editors learned that the researchers had misrepresented aspects of their work.

“Changes in rumen fermentation, bacterial community, and predicted functional pathway in Holstein cows with and without subacute ruminal acidosis during the periparturient period,” appeared in March in the Journal of Dairy Science. The senior author of the article was Shigeru Sato, of the Graduate School of Veterinary Sciences at Iwate University in Japan.

According to the retraction notice (which is only mentioned at the very bottom of the original article’s page, as a “linked article”):

Columbia grad student faked data in study of socioeconomics and life experiences, says retraction notice

Personality and Social Psychology Bulletin has retracted a 2018 paper because, according to a retraction notice, the first author changed data in a way that “resulted in incorrect and misleading results.”

The article, “Cardiovascular and self-regulatory consequences of SES-based social identity threat,” claims to show that socioeconomic status-based “social identity threat can go from ‘in the air’ to ‘under the skin’ to influence physiological and self-regulatory processes.” It has been cited twice in addition to the retraction notice, according to Clarivate Analytics’ Web of Science.

Here’s the retraction notice:

JAMA journal retracts its first paper, on exercise and heart disease

The authors of a 2019 meta-analysis in a JAMA journal on exercise and heart disease have retracted the paper after discovering that a quarter of the studies they’d used in the analysis did not belong.

The retraction is the first for the journal, which had published some 2,800 articles before having to pull one, Frederick P. Rivara, the editor in chief, told Retraction Watch. One in 2,800, we should note, is quite close to the 4 in 10,000 rate of retraction in the overall literature.

The study, from a group at the Universities of Manchester and Brighton, in the United Kingdom, was titled “Accelerometer- and pedometer-based physical activity interventions among adults with cardiometabolic conditions: a systematic review and meta-analysis,” and appeared in JAMA Network Open.

The authors, led by Alexander Hodkinson, looked at 36 randomized clinical trials and found that:
