Nature flags doubts over Google AI study, pulls commentary

A new editor’s note in Nature highlights concerns about a paper by Google researchers who claimed computer chips designed in just a few hours using artificial intelligence beat chip plans that human experts took months to develop.

In the note, published September 20, the journal stated:

Readers are alerted that the performance claims in this article have been called into question. The Editors are investigating these concerns, and, if appropriate, editorial action will be taken once this investigation is complete.

Nature pulls study that found climate fears were overblown

It was that rarest of things: a sliver of good news about climate change.

According to calculations published last year in Nature, our planet was keeping pace, and then some, with rising emissions from tropical forest clearance by gobbling up more and more atmospheric carbon.

“What we can mainly prove is that the worst nightmare scenarios of an impaired carbon sink have not yet materialised and that the news is not quite as bad,” Guido van der Werf, a professor at Vrije Universiteit Amsterdam, said in a press release at the time.

His coauthor Dave van Wees added:

Exclusive: Probe suggests new retraction awaiting embattled Korean heart doctor

A prominent physician-scientist in South Korea may soon be facing his fourth retraction. Last month, Hui-Nam Pak of Yonsei University was found guilty of duplicate publication, a form of academic misconduct, according to a report from the school’s committee on research integrity Retraction Watch has obtained.

Pak, a cardiologist, has had dozens of papers flagged on PubPeer. As we reported in February, journals pulled two of his papers the previous month after a whistleblower pointed out problems with the articles. One was retracted for “a number of issues related to scientific misconduct,” while the other was a duplicate publication. A third paper by Pak was retracted years earlier after mistakenly being published twice by the same journal.

Our February story triggered a flood of comments, many of them malicious. Some likened whistleblowing to “academic vandalism.” Others asserted that “whistleblowers deserve strong legal penalties” and that “immoral whistleblowers” seemed bent on ruining Pak’s “outstanding career.” Many comments were rejected for not adhering to our commenting policies, in particular making unsubstantiated claims.

The September 12 report from Yonsei University (in Korean) explains that an “informant” reported two of Pak’s papers to the school’s Research Ethics Integrity Committee on March 7.

Swedish beauty study that sparked ‘storm of criticism’ is cleared

The economist behind a controversial study showing attractive female students got lower grades after classes moved online during the pandemic has been acquitted of research misconduct, according to a report from his former institution.

But the researcher, Adrian Mehic, did not get off without reproof: Even if the work kept to the letter of the law, it may still have had “unethical consequences,” Erik Renström, vice-chancellor of Lund University in Sweden, wrote in the June 8 report (in Swedish).

In the study, a jury made up largely of final-year high schoolers rated the looks of university students based on pictures taken from social media accounts. The ratings were then linked to other publicly available data about the students, including academic performance. The findings, published in the journal Economics Letters in August 2022, made headlines across the globe.

But the students had not consented to the research, nor were they informed about it. The revelation unleashed “a storm of criticism at the university,” according to local media.

Overturning a dubious retraction proves difficult for education professor

For the past eight years, an education researcher in Spain has been waging an unsuccessful battle – including legal action – to quash a retraction she argues should never have happened.

Her paper, about the use of digital tools in early childhood education, was pulled by Computers & Education just months after it was published in 2015. According to the retraction notice, the article was submitted for publication while it was still under review at another journal, violating editorial policies against duplicate submission.

But according to the researcher, Elena Ramírez Orellana of the University of Salamanca, her paper had already been rejected by the first journal before it was sent to the other. She had the documents to prove it, she said, but that didn’t matter.

Withdrawn AI-written preprint on millipedes resurfaces, causing alarm

A preprint about millipedes that was written using OpenAI’s chatbot ChatGPT is back online after being withdrawn for including made-up references, Retraction Watch has learned.

The paper, fake references and all, is also under review by a journal specializing in tropical insects.

“This undermines trust in the scientific literature,” said Henrik Enghoff, a millipede researcher at the Natural History Museum of Denmark, in Copenhagen, who first spotted problems with the preprint, as we reported last month.

Ex-cops tangle with journals over strip clubs and sex crimes

A study by two economists who found opening strip clubs or escort services caused sex crimes in the neighborhood to drop contains “fatal errors” and should be retracted, argues a group of past and current law enforcement officers, including three academics.

“None of us are prudes or even anti-strip club,” Peter Moskos, a professor at John Jay College of Criminal Justice in New York City and a former Baltimore police officer, wrote in a thread on X (formerly Twitter). “But if you claim strip clubs reduce sex crimes – and by 13 percent! – you’re delving into serious policy issues.”

He added: “This is very typical of academics getting out of their field. They have second-hand data. They crunch the numbers … They don’t know what the data mean.”

Exclusive: World-renowned biologist accused of bullying student, stealing his work

One of the world’s foremost conservation biologists is being accused of plagiarism and bullying by a former PhD student, Retraction Watch has learned.

The biologist, Stuart Pimm of Duke University, strongly denies the charges, but he and his colleagues have acknowledged the existence of “closely related” work following an internal investigation by Duke.

The allegations surfaced late last month on X, formerly known as Twitter, in a thread that quickly went viral, garnering hundreds of thousands of views and drawing comments from a broad swath of scientists.

In the thread, Ruben Dario Palacio claimed his former academic advisor “threatened to kick me out of Duke” to make him work faster. Palacio decided to change labs due to the alleged “bullying and harassment,” he said, and three months later, in April 2020, published his research as a preprint. The article appeared in the journal Diversity and Distributions in October 2021.

Colombia drug regulator halts clinical research at US-funded facility

Following an inspection earlier this month, Colombia’s FDA has suspended all human research at a facility that until this summer had been receiving U.S. funding to develop a malaria vaccine.

The Malaria Vaccine and Development Center, in the city of Cali in western Colombia, is part of the Caucaseco Scientific Research Consortium, which is run by husband-and-wife team Myriam Arévalo-Herrera and Sócrates Herrera. The couple has secured more than $17 million from the U.S. National Institutes of Health (NIH) since 2003.

As we reported in April, an investigation by the group People for the Ethical Treatment of Animals (PETA) exposed a host of serious problems at the facilities, including widespread animal abuse and falsified research approvals. The NIH defunded the facilities in June, as first reported by STAT.

According to a statement released on August 5 (in Spanish), the Colombian National Institute of Drug and Food Surveillance (Invima) made the following findings during its inspection of the Malaria Vaccine and Development Center:

Florida university fires criminology professor blemished by retractions

Florida State University last week terminated a criminology professor accused of research misconduct, Retraction Watch has learned, capping a years-long, highly publicized saga the school says has caused almost “catastrophic” damage to its standing.

In a termination letter obtained by Retraction Watch, the university accused the former professor, Eric A. Stewart, of “extreme negligence and incompetence.” It also asserted that, due to Stewart’s actions, “decades of research” once believed “to be at the forefront of” criminology has “been shown to contain numerous erroneous and false narratives.”

“The details of problematic data management, false results, and the numerous publication retractions have negatively affected the discipline on a national level,” FSU Provost James J. Clark wrote in the letter, dated July 13.

Clark added that the debacle had also affected recruitment of faculty and students and caused the university’s researchers to worry about their chances of getting papers into top journals.
