Controversial Australian science journalist admits to duplication in her PhD thesis

Maryanne Demasi

A prominent (yet controversial) journalist in Australia has admitted to duplicating three images that were part of her PhD thesis — a practice outside experts agreed was acceptable, if not ideal, at the time, according to a report released today.

As part of an inquiry, the University of Adelaide convened an expert panel to investigate 17 allegations of duplication and/or manipulation in Maryanne Demasi’s 2004 thesis. Duplication is a common reason for retractions, such as when researchers use the same image to depict the results of different experiments.

After earning her PhD in rheumatology, Demasi became a journalist who got headlines for more than just her reporting. In 2013, she produced a controversial series about cholesterol and fat (which suggested they have been unfairly villainized, and which cast doubt on cholesterol-lowering drugs known as statins). A few years later, Demasi was fired from the science program Catalyst, after it aired an episode alleging wi-fi could cause brain tumors.

Regarding the allegations of misconduct in Demasi’s thesis, the originals of the images in question were long gone, so in 14 instances, an expert concluded it was not possible to conclude whether or not duplication had occurred. But in the remaining three instances, Demasi admitted she had “duplicated or probably duplicated” the images:

Oops: Springer Nature journal retracts the wrong paper

The Annals of Surgical Oncology (ASO) owes an apology to a group of researchers at two hospitals in South Florida.

Last month, the journal retracted a conference presentation about a device, from a company called Cianna Medical, that is designed to allow surgeons to home in to suspicious lumps in the breast and avoid needless damage to the surrounding tissue. According to the notice for “SAVI SCOUT RADAR – A non-wire non-radioactive localization device can be used for axillary lymph node surgery,” the authors of the study had failed to obtain ethics approval for the research, which was originally presented in April 2017 at the annual meeting of the American Society of Breast Surgeons.

Trouble is, that part about lack of ethics approval is not true.

A new “data thug” is born

Brendan O’Connor

In the last week, a lot more people know the name of Brendan O’Connor. Recently, the graduate student at the University of Leicester in the UK posted allegations on Twitter that a prominent psychologist at Cornell University, Robert Sternberg, had recycled large swaths of text in multiple publications. Since then, other so-called “data thugs” — such as Nick Brown and James Heathers — have added their voices to the discussion. Sternberg recently resigned as editor of Perspectives on Psychological Science, in part over concerns about his practice of frequently citing his own papers. We spoke with O’Connor about the response to his allegations — and why he took to Twitter to raise them. (Note: O’Connor’s opinions are his own, and not necessarily representative of his institution.)

Prominent researcher dismissed following misconduct probe

Yoshinori Watanabe

The University of Tokyo has fired a high-profile cell biologist after a probe determined his group had falsified data.

According to a news release issued today (in Japanese), the university has issued a “disciplinary dismissal” of Yoshinori Watanabe (according to our Google translate of the notice).

In 2016, the institution began an investigation of seven papers from Watanabe’s lab after receiving anonymous allegations. In August 2017, the university announced the result: Five papers contained falsified or fabricated images. One — a 2015 Science paper — has already been retracted.

According to Clarivate Analytics’ Web of Science, Watanabe has published more than 100 papers, which have been cumulatively cited thousands of times.

Last year, regarding the Science retraction, Watanabe told us:

Chemists duke it out over who was first to discover a 30-year-old technique

Decades ago, unbeknownst to each other, two chemists were independently working on a screening approach to identify new potential drugs. Both published papers about the technique around the same time. So now, when scientists write papers that cite the technique, who should get credit for discovering it?

Decades later, that question still hasn’t been answered — and the researchers continue to argue, this time over one’s decision not to cite the other’s work.  

More than 30 years ago, Árpád Furka—now retired from Eötvös Loránd University in Budapest—developed an approach he says has had “outstanding importance” in drug development. The technique, called split-mix synthesis, made it possible to synthesize and screen millions of peptides at once, instead of one by one. Furka patented the method in 1982, presented an abstract in 1988, and published a paper in 1991. Continue reading Chemists duke it out over who was first to discover a 30-year-old technique

Researcher loses battle with Cell over wording of retraction notice

For months, a researcher has wrestled with a journal over the wording of an upcoming retraction notice. It appears that she has lost.

Earlier this week, Cell retracted the paper, despite the protests of first author Shalon Babbitt Ledbetter. When Ledbetter learned the journal was planning to retract the biochemistry paper over image manipulations, but wouldn’t name the culprit in the notice, she shared her concerns on PubPeer. Although a 2015 letter sent to Cell from Saint Louis University identified last author Dorota Skowyra as responsible for multiple manipulations, the journal wasn’t planning to say Skowyra was responsible in the retraction notice. Which would leave all other authors — particularly Ledbetter — under a cloud of suspicion.

Now, Cell Press has finally retracted the paper, along with another paper in Molecular Cell that lists Skowyra as corresponding author. Both notices describe image manipulations that were investigated by Saint Louis University (SLU). Neither identifies who is responsible.

Author under fire has eight papers retracted, including seven from one journal

A researcher whose work on the use of nanomaterials has been heavily scrutinized on PubPeer — with one critic alleging a paper contained “obviously fabricated” images — has lost eight papers. [Editor’s note: See update below.]

The eight articles — seven from Biosensors and Bioelectronics and one from Analytica Chimica Acta, both published by Elsevier — all cite issues related to duplications, and conclude with some version of the following:

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

That study reporting worrisome levels of zinc in tuna? It’s being retracted

Recently, a rash of news outlets posted concerns that canned tuna and other products may contain potentially dangerous levels of zinc. They were all wrong.

News outlets such as The Daily Mail and The Sun reported findings from a recent study, which showed that canned foods such as tuna may contain 100 times the daily limit of zinc — raising concerns about how such huge doses of the mineral could be causing digestion problems. The last author of the study told Retraction Watch the paper is going to be retracted, because the authors made a fundamental error calculating the amount of zinc present in canned foods.

Last week, the UK’s biggest health website NHS Choices posted a critique of the paper, in which they recalculated the levels of zinc present in canned foods:

“Youth Guru” loses turkey-neck paper that overlapped with book chapter

Ronald Moy

A prominent cosmetic surgeon and his daughter have lost a 2017 paper on treating men with excessive neck flab — otherwise known as “turkey neck” — because much of the work appears to have duplicated a book chapter he co-authored about the topic.

The first author of the retracted article is Ronald L. Moy, a plastic surgeon to the stars in Beverly Hills, Calif., and a past president of both the American Academy of Dermatology and the American Society of Dermatology. In a 2012 article about area plastic surgeons, LA Confidential Magazine dubbed Moy the “youth guru” and a local leader in the use of “new research and a comprehensive approach to restore a youthful complexion—no cutting required.”

His co-author was his daughter, Lauren Moy, who appears to be working with him in his Rodeo Drive dermatology practice.
