Nature Cell Bio paper may be headed for retraction

ncbA Nature Cell Biology paper published only a few months ago by prominent researchers in Taiwan has sparked a heated discussion on PubPeer, which now includes a comment allegedly from an author saying they have requested its retraction.

Although a representative of the journal wouldn’t confirm to us that the authors had requested a retraction, the comment on PubPeer says the paper contains several figures that were “inappropriately manipulated” by the first author.

Here’s the full comment on PubPeer, tagged as coming from one of the authors of the paper:

A diabetes researcher with eight retractions — despite his attempts to block some in court — has received a new batch of research funding.

According to a release from public funding agency Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP), Mario Saad is among 33 researchers who will receive funding from partnerships between federal and state agencies, including FAPESP.

It’s unclear how much Saad’s project will individually receive, but the total for all projects exceeds 640 million Brazilian Real, equivalent to $185 million USD.

Saad’s name should be familiar to our readers.

Prominent researcher in Scotland resigns after misconduct finding upheld

Robert Ryan

A rising star in the field of infectious disease has resigned from the University of Dundee in Scotland after the university upheld the findings of an investigation concluding that he committed misconduct.

Earlier this year, Robert Ryan was suspended amidst the investigation, which focused on data doctoring in several publications. We’ve now been forwarded an internal email from Julian Blow, dean of the School of Life Sciences, which alerts staff that Ryan has resigned, and the institution has upheld its finding of misconduct, despite Ryan’s appeal.

In 2015, Ryan was selected to be an EMBO Young Investigator; yesterday, EMBO announced that it had withdrawn him from the program.

Blow’s email to staff, dated November 9, states:

Official notice published for chem paper slated for retraction in 2011

process-safetyAfter five years, Elsevier has finally issued a notice of retraction for a paper it announced it was pulling for fraud in 2011.

All of the papers were produced by a research group in Brazil; all were retracted after the publisher conducted an investigation, concluding that the NMR results had been manipulated. At the time, the last author on the latest retraction, Claudio Airoldi, defended the work. Since then, however, Airoldi has logged two more retractions, bringing his total to 13.

Here’s the full text of the retraction notice, from Process Safety and Environmental Protection: Continue reading Official notice published for chem paper slated for retraction in 2011

Genetics study flagged for reliability issues by Frontiers journal

frontiers-in-geneticsA genetics journal has issued an expression of concern (EOC) for a study after an investigation by its chief editors.

According to the notice in Frontiers in Genetics, the authors of the paper — based at Hokkaido University in Sapporo, Japan — are conducting further experiments to resolve the issues raised by the journal’s investigation.

In February, the same paper received a corrigendum due to errors in the assembly of one of the figures.

Here’s the EOC, issued earlier this week: Continue reading Genetics study flagged for reliability issues by Frontiers journal

Former Duke researcher at center of lawsuit lodges 16th retraction

ajrcmb-2016-55-issue-5-coverTwo former researchers at Duke University at the center of a lawsuit by a whistleblower to recoup millions in federal funding have lost yet another paper.

This is hardly the first retraction for Erin Potts-Kant, who used to work in the pulmonary lab of now-retired William Michael Foster. Earlier this year, a lawsuit filed by a former colleague of Potts-Kant and Foster was unsealed alleging that the pair — along with the university — included fraudulent data in materials involving more than 60 grants, worth hundreds of millions of dollars.

That is the legal side of their story. The science publishing side is that Potts-Kant and Foster have been steadily adding to their list of retractions — this paper represents her 16th, and his 13th.

Here’s the notice for “Nitric oxide mediates relative airway hyporesponsiveness to lipopolysaccharide in surfactant protein A-deficient mice:” Continue reading Former Duke researcher at center of lawsuit lodges 16th retraction

Authors retract third cancer paper for missing original data

international-journal-of-oncologyResearchers have retracted their third paper due to missing original data, following an investigation at their former institution in New York.

We’ve previously reported on two retractions of papers co-authored by Bhagavathi Narayanan and Narayanan K. Narayanan, previously based at the New York University (NYU) School of Medicine. The studies were pulled when the pair couldn’t provide original images to investigators at NYU School of Medicine. One author has blamed the lack of original data on the abrupt closure of her previous institution in 2004, after it allegedly misspent millions in federal grants. 

However, the latest retraction affects a paper published eight years later in the International Journal of Oncology. Its coauthors include Bhagavathi Narayanan, Narayanan K. Narayanan and Rajkishen Narayanan; we haven’t been able to uncover if there is a relation between them.

A spokesperson for the NYU School of Medicine sent us this statement: Continue reading Authors retract third cancer paper for missing original data

A biologist at the University of Georgia has lost a paper after an investigation revealed she had tampered with three images.

In 2014, Azza El-Remessy notched three retractions for a series of image errors. Now, a fourth retraction notice, and an expression of concern, explain there has been an investigation into her work. The investigation — conducted by two Georgia institutions, along with the Charlie Norwood Veterans Affairs Medical Center, where El-Remessy has additional appointments — has found evidence of misconduct.

The retraction notice for “Oxidative stress inactivates VEGF survival signaling in retinal endothelial cells via PI 3-kinase tyrosine nitration” explains:

Leading diabetes researcher acted negligently, probe concludes

Kathrin Maelder
Kathrin Maedler

Several duplications in the work of a prominent diabetes researcher were the result of negligence, but there is not enough evidence to support charges of misconduct, according to an investigation at her university in Germany.

Recently, we’ve reported on several notices for papers co-authored by Kathrin Maedler, a researcher at the University of Bremen. So far, Maedler has one retraction, multiple corrections, and two expressions of concern to her name, after several of her papers were questioned on PubPeer. Previously, the University of Zurich in Switzerland — where Maedler completed her PhD in 2002 — determined there was a lack of evidence to support allegations of misconduct in papers that were part of her doctoral thesis. 

Last week, the University of Bremen released its own investigation report (in German), which we translated using One Hour Translation. It concludes that Maedler Continue reading Leading diabetes researcher acted negligently, probe concludes
