Susana González

A promising early career researcher has been dismissed from her post at the National Center for Cardiovascular Research (CNIC) in Spain, following “an alleged ongoing fraud,” according to El Pais.

We don’t know what exactly the internal investigation into Susana González’s work found; El Pais relied on anonymous sources, and the CNIC confirmed only that they dismissed her on February 29th. There are allegations against her work on PubPeer, but we don’t know what role those played in the investigation.

(We had the story translated; here’s a PDF of the article in English.)

González denies that she committed misconduct, the paper reports:

When misconduct strikes: A fictional tale

Raw dataPernille Rørth is not your typical novelist. She was a scientist for 25 years and was also editor-in-chief of the EMBO Journal for five years. But now, she’s written a novel – Raw Data – about an incident of misconduct that forces a top lab in Boston to retract a prominent Nature paper. The novel exposes how scientists – even the most well-intentioned – can crack under the intense pressure of such a career-killing event. (There’s even a twist at the end.) We spoke to Rørth about her novel, and what she wants it to achieve.

Retraction Watch: Misconduct is – thankfully – a relatively rare event in science. Why write a novel about it? Continue reading When misconduct strikes: A fictional tale

Sample tampering leads to plant scientist’s 7th retraction

Jorge Vivanco
Jorge Vivanco

Plant scientist Jorge Vivanco has earned his seventh retraction, after an investigation found data from soil samples were “intentionally fabricated by a third party.”

Vivanco and his former postdoc Harsh Bais made a name for themselves by discovering the secret behind a nasty invasive plant: It secretes a harmful form of catechin, which kills everything around it, suggesting it could serve as a new herbicide. The findings earned the researchers a story in the New York Times.

In the newly retracted paper, published in 2005, first author Laura Perry — then a postdoc at Colorado State University — further explored the role of the plant-killer, working with Vivanco as the last author. However, when a team working in the building next door had trouble finding catechin in their samples, Perry took another look, and concluded that her samples had been tampered with.

In other words, Perry told us:   Continue reading Sample tampering leads to plant scientist’s 7th retraction

Author with seven retractions makes Thomson Reuters list of top scientists — plus another twist

Bharat Aggarwal

A cancer researcher who recently retired from MD Anderson Cancer Center —  and also recently lost seven papers from one journal following a multi-year investigation — is one of the world’s top scientists, according to a new ranking.

In Thomson Reuters Web of Science’s 2015 list of The World’s Most Influential Scientific Minds, Bharat Aggarwal’s name tops the section for Pharmacology and Toxicology (see p. 89). In all fairness, the list is presented in alphabetical order, and seven of Aggarwal’s papers have each been cited at least 1,000 times. But in addition to his recent seven retractions, he has has six corrections, two unexplained withdrawals, and two Expressions of Concern.

We contacted Thomson Reuters Web of Science to inquire, and a spokesperson told us: Continue reading Author with seven retractions makes Thomson Reuters list of top scientists — plus another twist

EMBO awardee under investigation loses grant

Sonia Melo, the recipient of an early career award from the European Molecular Biology Organization (EMBO) who fell under investigation after one of her papers was retracted, has now lost the grant.

On the EMBO release announcing the nine awardees of the 2015 Installation Grants, there now appears an asterisk beside Melo’s name. At the bottom of the page, this message appears: Continue reading EMBO awardee under investigation loses grant

Journals flag 6 papers, request investigation of New Jersey university biologists

Two journals have published six expressions of concern for a pair of biologists at Rowan University, and are asking the university to undertake an investigation.

We contacted the editors of the two journals — Journal of Cell Science and Biology Open — who both said they decided to flag the papers after a reader raised concerns about potential re-use of blot images. The six papers are co-authored by John G. Pastorino, a molecular biologist at Rowan University in New Jersey and Nataly Shulga, whose LinkedIn identifies her as a research specialist at the same institution. According to the nearly identical notes, the journals (which share a publisher) undertook a review of the original data, but “felt unable to resolve this matter.”

The expressions of concern — five from the  Journal of Cell Science and one from Biology Open — include pretty much the same text. Here’s the note that appeared in JCS:

STAP stem cell researcher Obokata loses another paper

Nature protocols

The first author of two high-profile Nature retractions about a technique to easily create stem cells has lost another paper in Nature Protocols.

Haruko Obokata, once “a lab director’s dream,” according to The New Yorker, also had her PhD revoked from Waseda University last fall.

After learning of concerns that two figures are “very similar” and “some of the error bars look unevenly positioned,” the rest of the authors were unable to locate the raw data, according to the note. The journal could not reach Obokata for comment before publishing the retraction.

“Reproducible subcutaneous transplantation of cell sheets into recipient mice” has been cited 21 times, according to Thomson Reuters Web of Science. It was published in June 2011, soon after Obokata earned her PhD. 

Here’s the note:

Sweden, rocked by scientific scandals, re-thinking how it investigates misconduct

Flag_of_Sweden.svgThe Swedish government is taking a second look at how it handles misconduct investigations.

According to a spokesperson:

Yes, we have an national investigation ongoing since last autumn. It will investigate how misconduct is investigated and handled in Sweden…

She also sent us a link to a description of the investigation, in Swedish. The outcome of the investigation is expected in November, 2016.

The inquiry predates the media implosion that’s taken place in recent months over the Karolinska Institutet’s (KI) investigation of surgeon Paolo Macchiarini, who transplanted tracheas seeded with patients’ own stem cells.

Doctor suspended in UK after faking co-authors, data

Screen Shot 2016-02-24 at 11.04.56 AMA doctor in Manchester, UK has received a year’s suspension by the Medical Practitioners Tribunal Service.

Gemina Doolub admitted that she fabricated research data and submitted papers without the knowledge of her co-authors, including faking an email address for a co-author, a news story in the BMJ reports. The research in question was part of two retractions that Doolub received in 2013, one of which we covered at the time.

Doolub’s research examined ways to treat and avoid microvascular obstruction — that is, blocked arteries. Doolub did the work while at Oxford.

“Intracoronary Adenosine versus Intravenous Adenosine during Primary PCI for ST-Elevation Myocardial Infarction: Which One Offers Better Outcomes in terms of Microvascular Obstruction?” was published in International Scholarly Research Notices Cardiology and has not yet been cited, according to Thomson Reuters Web of Science.

As the BMJ reports, in that paper,

Psychologist Jens Förster earns second and third retractions as part of settlement

Jens Förster

High-profile social psychologist Jens Förster has earned two retractions following an investigation by his former workplace. He agreed to the retractions as part of a settlement with the German Society for Psychology (DGPs).

The papers are two of eight that were found to contain “strong statistical evidence for low veracity.” According to the report from an expert panel convened at the request of the board of the University of Amsterdam, following

an extensive statistical analysis, the experts conclude that many of the experiments described in the articles show an exceptionally linear link. This linearity is not only surprising, but often also too good to be true because it is at odds with the random variation within the experiments.

One of those eight papers was retracted in 2014. In November, the American Psychology Association received an appeal to keep two of the papers, and Förster agreed to the retractions of two more:
