Authors retract Nature paper projecting high costs of climate change

The authors of a highly publicized study predicting climate change would cost $38 trillion a year by 2049 have retracted their paper following criticism of the data and methodology, including that the estimate is inflated. 

“The economic commitment of climate change,” which appeared April 17, 2024, in Nature, looked at how changes in temperature and precipitation could affect economic growth. Forbes, the San Diego Union-Tribune and other outlets covered the paper, which has been accessed over 300,000 times. It has been cited 168 times, according to Clarivate’s Web of Science.

But after two commentaries published this August raised questions about the study’s data and methodology, the researchers revisited their findings. “The authors acknowledge that these changes are too substantial for a correction,” the retraction notice, published today, states.

Paper on homeopathy for ADHD retracted for ‘deficiencies’

Michael Teut

A paper touted as “the first systematic review and meta-analysis” of research on the effects of homeopathy for attention deficit and hyperactivity disorder (ADHD) has been retracted more than a year after critics first contacted the journal with concerns. 

The article, “Is homeopathy effective for attention deficit and hyperactivity disorder? A meta-analysis,” appeared in Pediatric Research, a Springer Nature title, last June. It has not been cited in the scientific literature, according to Clarivate’s Web of Science, but Altmetric, which quantifies the online attention papers receive, ranks the paper in the top 5% of all articles ever tracked. 

The original paper concluded: 

Individualized homeopathy showed a clinically relevant and statistically robust effect in the treatment of ADHD.

However, the retraction notice, dated September 20, detailed four “concerns regarding the analysis of the articles included in the meta-analysis,” and concluded:

A German vocabulary lesson: Paper retracted because an “individuelle Heilversuche” is not a clinical trial

by mcmurryjulie

A co-editor of the Journal of Neurology has retracted a 2018 paper he helped write because the way the paper was written misled readers about the nature of the research. 

The article, “Menière’s disease: combined pharmacotherapy with betahistine and the MAO-B inhibitor selegiline—an observational study,” purported to describe the effects of a combination treatment to reduce the incidence of dizziness in people with Menière’s, a neurologic disorder that affects the inner ear. 

The first author of the paper is Michael Strupp, of the Munich Center for Neurosciences at Ludwig-Maximilians-University in Munich. Strupp also is one of a troika of editors in-chief of the Journal of Neurology.

According to the abstract:

Management researcher with 16 retractions has new professorship

Ulrich Lichtenthaler

Ulrich Lichtenthaler, a management professor who has had to retract 16 papers for data irregularities, has a new position in academia.

According to a news release from the International School of Management (ISM), a business school based in Germany, Lichtenthaler has been appointed Professor of Business Management and Entrepreneurship at the Cologne campus. Lichtenthaler is also taking over as one of the directors of the Entrepreneurship Institute at ISM, which conducts research in the field.

Lichtenthaler’s name may be familiar to readers: After journals retracted more than a dozen of his articles, he resigned from a previous post at the University of Mannheim in 2015.

We emailed Lichtenthaler to ask if he had disclosed his history to his new employers; he forwarded the email to ISM’s head of marketing and sales, who told us:

Flawed climate science paper “exposed potential weaknesses” in the peer review process

Before we present this new post, a question: Do you enjoy reading Retraction Watch? If so, we could really use your help. Would you consider a tax-deductible donation to support our work? Thanks in advance.

How did a deeply flawed paper, which contradicts mainstream science on climate change, pass peer review?

That is what three editorial board members tried to figure out after the journal, Global and Planetary Change, faced heavy criticism for publishing the controversial paper last year. The board members published their findings earlier this month in a commentary.

Martin Grosjean, the corresponding author on the editorial, told Retraction Watch that the editors and publisher, Elsevier, share the same interest: Continue reading Flawed climate science paper “exposed potential weaknesses” in the peer review process

Caught Our Notice: “The first author cut the thermoprinter paper printout into pieces and reassembled them”

Title: A mitochondrial ferredoxin is essential for biogenesis of cellular iron-sulfur proteins

What Caught Our Attention: Here’s a cut-and-paste issue that gave us pause. The authors of an 18-year-old paper in PNAS corrected it after realizing some bands in a figure were duplicated (an issue raised on PubPeer one year ago). It turns out, the first author had cut the paper into pieces and reassembled them to present the blots in the “desired order,” and some had become duplicated by mistake. The overall results were unaffected, so the journal swapped the image with a corrected version.

Most board members of journal resign to protest new editor, layoffs

Detlev Ganten

Nearly all of the editorial board members of a 150-year-old journal about the molecular underpinnings of medicine and disease have resigned their posts, protesting changes by publisher SpringerNature that they say “jeopardized the future and scholarly legacy of the Journal.”

In a December 1 letter, led by the three former editors in chief of the Journal of Molecular Medicine — Detlev Ganten, Gregg Semenza and Thomas Sommer — more than 70 then-editorial board members raised two objections: closing a small editorial office and laying off staff, and unilaterally appointing a new editor.

Regarding the decision to close the office at the Max Delbrück Center for Molecular Medicine (MDC) Berlin Buch, where it has been since 1995,  the editors and board members wrote: Continue reading Most board members of journal resign to protest new editor, layoffs

Former director earns two-year funding ban after misconduct finding

A researcher found guilty of misconduct earlier this year has been temporarily banned from funding by the German Research Foundation.

The Foundation’s decision, issued on Dec. 14, 2017, comes six months after the Leibniz Association, made up of 91 independent research institutions, found Karl Lenhard Rudolph guilty of “grossly negligent scientific misconduct.” The research body identified “errors in data representation” in eight of 11 papers and found Rudolph responsible for the issues in seven of them. In June, the Leibniz Association sanctioned Rudolph, and announced he was no longer directing the Leibniz Institute on Aging – Fritz Lipmann Institute.

Boys will be boys: Data error prompts U-turn on study of sex differences in school

The authors of a 2017 paper on emotional and behavioral gaps between boys and girls have retracted the article after discovering a coding error that completely undermined their conclusions.

The revelation prompted the researchers to republish their findings in the same journal, this time with a title that flips the narrative.

The PsychJournal study, first published in March, looked at self-regulation — loosely defined as the ability to get stuff done and keep a lid on it —  in boys and girls in German elementary schools. Although previous studies had found girls might do better on this front, the authors, from the University of Leipzig and New York University’s Abu Dhabi campus, initially found the opposite:

Post-publication peer review in action: Science flags paper just days after publication

Science has issued an expression of concern for a widely covered materials science paper published on Friday, citing issues with the supplementary data.

The paper — which caught the attention of multiple news outlets — added properties to cotton fibers in vitro, potentially enabling researchers to manufacture fabric that can fluoresce or carry magnetic properties.

The move to issue an expression of concern was unusually quick. According to the journal, an expert who received the paper from a journalist under a media embargo contacted Science to flag issues in some of the supplementary data. At the time of this post, the paper does not yet have an entry on PubPeer.

Here’s the full expression of concern:
