“Social science isn’t definitive like chemistry:” Embattled food researcher defends his work

Brian Wansink

It’s been a busy few months for Brian Wansink, a prominent food researcher at Cornell University. A blog post he wrote in November prompted a huge backlash from readers who accused him of using problematic research methods to produce questionable data, and a group of researchers suggested four of his papers contained 150 inconsistencies. The scientist has since announced he’s asked a non-author to reanalyze the data — a researcher in his own lab. Meanwhile, criticisms continue to mount. We spoke with Wansink about the backlash, and how he hopes to answer his critics’ questions.

A “plethora of data errors” prompts authors to retract oncology paper

Researchers in China have retracted a 2016 cancer imaging paper because they introduced “a plethora of data errors” while preparing the article for submission.

Although the retraction notice provides no details on what these errors are or how exactly they occurred, it does point the finger at the researchers, explaining that the data errors happened as a result of their “negligence.”

Here’s the 2017 retraction notice for “Rituximab-conjugated, doxorubicin-loaded microbubbles as a theranostic modality in B-cell lymphoma,” published November 25, 2016 in Oncotarget: Continue reading A “plethora of data errors” prompts authors to retract oncology paper

Researcher issues massive changes to papers amidst plagiarism investigation

A researcher in Greece has issued extensive — what we sometimes call “mega” — corrections to two 2016 papers published in a medical journal in Romania.

The first author — Alexandra Kalogeraki, a pathology researcher at the University of Crete in Greece — retracted two reviews from the same journal last year for plagiarism. The newest notices remove authors and correct, add, or remove text, often without providing an explicit reason for the change.

The journal told us Kalogeraki initially asked to retract the newly corrected papers, but the editors didn’t believe that the papers warranted the harsher measure, as they’d run a plagiarism scan and conducted peer review of the two papers and did not find any issues. However, the University of Crete is currently investigating allegations of plagiarism in two of Kalogeraki’s other papers, which have already been retracted by the same journal.

For the latest mega-corrections, both are so lengthy we’re only including a small portion of the notice for the case study, “Recurrent Cerebellar Desmoplastic/ Nodular Medulloblastoma in Cerebrospinal Fluid (CSF) in the elderly. A Cytologic Diagnosis,” which deals with authorship: Continue reading Researcher issues massive changes to papers amidst plagiarism investigation

Researchers disagree over how to explain doubts over physics findings

After an international group of physicists agreed that the findings of their 2015 paper were in doubt, they simply couldn’t agree on how to explain what went wrong. Apparently tired of waiting, the journal retracted the paper anyway.

The resulting notice doesn’t say much, for obvious reasons. Apparently, some additional information came to light which caused the researchers to question the results and model. Although the five authors thought a retraction was the right call, they could not agree on the language in the notice.

Here’s the retraction notice for “Atomistic simulation of damage accumulation and amorphization in Ge,” published online February 2015 in the Journal of Applied Physics (JAP) and retracted two years later in January 2017: Continue reading Researchers disagree over how to explain doubts over physics findings

Researcher sued to stop retractions; he just earned two more and is now up to 11

The notices keep coming for diabetes researcher Mario Saad.

Diabetes has just retracted two more of his papers, both of which had been flagged by expressions of concern, citing problems with duplications. What’s more, the journal added another expression of concern to a 2009 paper on which Saad — based at the University of Campinas in São Paulo, Brazil — is listed as last author, again over concerns of duplication.

This isn’t Saad’s first run-in with the journal: In 2015, the researcher sued the publisher, the American Diabetes Association, after it issued expressions of concern for four of his papers. Later that year, a judge dismissed Saad’s defamation suit. The journal eventually retracted the papers.

The latest articles flagged by Diabetes appear to be part of an intricate publishing web, as the journal suggests all papers have used features of previous papers, and also include elements that have been republished by subsequent articles.

Here’s the first retraction notice, for “A Central Role for Neuronal AMP-Activated Protein Kinase (AMPK) and Mammalian Target of Rapamycin (mTOR) in High-Protein Diet–Induced Weight Loss:”

Does a paywall protect patient privacy?

A psychoanalyst has retracted an award-winning 2016 paper over concerns that it contained “sensitive” patient information.

On July 15, Judith L. Mitrani, a psychoanalyst based in California, published an article that included “sensitive clinical material” about a patient. Although we do not know what prompted the concerns, on November 21, Mitrani, in agreement with the journal’s editor-in-chief and publisher, retracted the article. The author and editor told us the retraction was meant to prevent non-experts from accessing the paper and to stop other non-Wiley sites from posting it.

The article was published after it had won the journal’s essay contest in 2015.

Here’s the retraction notice for “On Separating One from the Other: Images of a Developing Self,” published in the British Journal of Psychotherapy (BJP):

Journal retracts paper by state senator (and former mathematician)

Daniel Biss

Here’s something you don’t see every day: A state senator with an academic publication record, in his former career as a mathematician. Even more unusual: A retraction of one of his 15-year-old papers, after the journal realized most of the results were incorrect.

According to the notice, some aspects of the paper by Daniel Biss — now a democratic Illinois State Senator — are also “ambiguous.”

We spoke with Senator Biss, who told us he had been contacted by an editor who told him someone had raised questions about the paper, but he didn’t have much input in the notice:

Authors pull virus replication paper after they cannot replicate results

Researchers in China have retracted a 2016 paper exploring the replication behaviors of a retrovirus, after discovering that the key results could not be reproduced — possibly because their cell cultures had been contaminated.

The authors also cite a disagreement with a colleague, who they say contributed to the work but does not want to be listed as an author.

Here’s the retraction notice for “Nuclear import of prototype foamy virus transactivator Bel1 is mediated by KPNA1, KPNA6 and KPNA7,” published in the International Journal of Molecular Medicine: Continue reading Authors pull virus replication paper after they cannot replicate results

Journal pulls paper with missing data, citing inquiry and legal proceedings

A journal has retracted a 2012 paper after the last author was unable to provide material to support the results presented in multiple figures.

The lack of supporting data came out during “an internal inquiry and subsequent legal proceedings,” according to the notice, issued by Cell Cycle.

The last author on the paper is Susana Gonzalez, who was dismissed from her position at the National Center for Cardiovascular Research (CNIC) in Spain last year.

Here’s the full notice:

Why traditional statistics are often “counterproductive to research the human sciences”

Andrew Gelman

Doing research is hard. Getting statistically significant results is hard. Making sure the results you obtain reflect reality is even harder. In this week’s Science, Eric Loken at the University of Connecticut and Andrew Gelman at Columbia University debunk some common myths about the use of statistics in research — and argue that, in many cases, the use of traditional statistics does more harm than good in human sciences research. 

Retraction Watch: Your article focuses on the “noise” that’s present in research studies. What is “noise” and how is it created during an experiment?
