How much does a retracted result pollute the field?

Research Integrity and Peer Review

When a paper is retracted, how many other papers in the same field — which either cite the finding or cite other papers that do — are affected?

That’s the question examined by a study published in BioMed Central’s new journal, Research Integrity and Peer Review. Using the case of a paper retracted from Nature in 2014, the authors found that subsequent research that cites the retracted paper often repeats the problematic finding, thereby spreading it throughout the field. However, papers that indirectly cited the retracted result — by citing the papers that cited the Nature paper, but not the Nature paper itself — typically don’t repeat the retracted result, which limits its spread.

Here’s how the authors describe their findings in the paper: Continue reading How much does a retracted result pollute the field?

Macchiarini did not obtain necessary ethics approvals, says Swedish Research Council

lancetSurgeon Paolo Macchiarini did not apply for the necessary ethics approval to perform the pioneering transplants he’s known for, according to the Swedish Research Council.

Chief Legal Counsel Anna Hörnlund, who wrote a letter in this week’s The Lancet, says Macchiarini’s work needed to obtain ethical approval from one of six regional ethical review boards, as required by Swedish law — and neither Macchiarini nor his former employer, Karolinska Institutet, did so:

Retraction count for Shigeaki Kato climbs to 39

We’ve found another retraction for Shigeaki Kato, number seven on our leaderboard.

Our count for Kato has now risen to 39; we added five retraction notices to our count for Kato last month. These notices follow an investigation at the University of Tokyo, where Kato used to work, which found 43 papers contained “likely altered or forged materials,” according to a 2013 news article from The Asahi Shimbun.

Here’s the retraction note for “1alpha,25(OH)2D3-induced DNA methylation suppresses the human CYP271B1 gene,” published in Molecular and Cellular Endocrinology:

Plant scientist Voinnet’s correction count grows to 22

nature structure molecular biologyWe have found another correction for high-profile plant scientist Olivier Voinnet, bringing his total count to 22. Voinnet, who works at ETH Zurich, also has seven retractions, a funding ban, and a revoked award.

Voinnet’s most recent corrections involve problems with figures; the same issue is cited in this latest correction notice, for “Competition for XPO5 binding between Dicer mRNA, pre-miRNA and viral RNA regulates human Dicer levels.”

The correction notice in Nature Structural & Molecular Biology, issued earlier this year, explains:

“Science advances incrementally:” Researchers who debunked gay canvassing study move field forward

David Broockman
Joshua Kalla

How easy is it to change people’s minds? In 2014, a Science study suggested that a short conversation could have a lasting impact on people’s opinions about gay marriage – but left readers disappointed when it was retracted only months later, after the first author admitted to falsifying some of the details of the study, including data collection. We found out about the problems with the paper thanks to Joshua Kalla at the University of California, Berkeley and David Broockman at Stanford University, who tried to repeat the remarkable findings. Last week, Kalla and Broockman published a Science paper suggesting what the 2014 paper showed was, in fact, correct – they found that 10-minute conversations about the struggles facing transgender people reduced prejudices against them for months afterwards. We spoke with Kalla and Broockman about the remarkable results from their paper, and the shadow of the earlier retraction.

Retraction Watch: Let’s start with your latest paper. You found that when hundreds of people had a short (average of 10 minutes) face-to-face conversation with a canvasser (some of whom were transgender), they showed more acceptance of transgender people three months later than people with the same level of “transphobia” who’d talked to the canvasser about recycling. Were you surprised by this result, given that a similar finding from Michael LaCour and Donald Green, with same-sex marriage, had been retracted last year?

DC court allows part of lawsuit against GW to proceed

kumarA DC court has denied part of George Washington University’s motion to dismiss a $8 million lawsuit by a biologist who claims his employer mishandled an investigation into his work.

Last spring, GW filed a motion to dismiss the case, brought forward by Rakesh Kumar, who has three retractions.  A judge has allowed the case to proceed, honoring parts of the school’s motion to dismiss, but denying most of it.

The memorandum opinion gives the specifics:

Do interventions to reduce misconduct actually work? Maybe not, says new report

Elizabeth Wager and Ana Marusic

Can we teach good behavior in the lab? That’s the premise behind a number of interventions aimed at improving research integrity, invested in by universities across the world and even private companies. Trouble is, a new review from the Cochrane Library shows that there is little good evidence to show these interventions work. We spoke with authors Elizabeth Wager (on the board of directors of our parent organization) and Ana Marusic, at the University of Split School of Medicine in Croatia.

Retraction Watch: Let’s start by talking about what you found – looking at 31 studies (including 15 randomized controlled trials) that included more than 9500 participants, you saw there was some evidence that training in research integrity had some effects on participants’ attitudes, but “minimal (or short-lived) effects on their knowledge.” Can you talk more about that, including why the interventions had little impact on knowledge?

Image splicing, duplications, inversions kill paper for well-known longevity researcher and alum of lab

Gizem Domnez
Gizem Donmez

A well-known scientist at the Massachusetts Institute of Technology who studies longevity has retracted a paper for “numerous examples of unindicated splicing of gel lanes,” as well as other problems.

This is Leonard Guarente‘s second retraction. He shares both with Gizem Donmez, an alum of his lab who now has three retractions. Donmez left her post as a Tufts professor in 2014.

Guarente told us in March — when we reported that he’d published a mega-correction on another paper — that he had planned to address issues with the paper, “SIRT1 Protects against α-Synuclein Aggregation by Activating Molecular Chaperones,” published in the The Journal of Neuroscience. Now, a retraction note has appeared “at the request of the authors.” It explains:

Poll: Should co-authors of a scientific paper be allowed to change their minds?

lancetSince we reported Friday that multiple authors had asked to remove their names from a high-profile 2011 Lancet paper about a risky transplant surgery, a few readers have wondered: Should this be allowed?

To recap: The same day the journal announced it was tagging the controversial paper with an expression of concern, it issued a new erratum about the paper, removing three author names (one had already asked to be removed earlier). The highly cited paper has been under scrutiny ever since the last author, Paolo Macchiarini, has been facing allegations of misconduct, which most recently led to Macchiarini’s dismissal from the Karolinska Institutet. (Here’s our timeline of events to keep you abreast.)

It’s not surprising that a few of Macchiarini’s co-authors would want to distance themselves from this ever-expanding scandal, but should authors who originally signed onto a paper be able to change their minds? Let us know in our poll, below. Continue reading Poll: Should co-authors of a scientific paper be allowed to change their minds?

Cancer researcher earns 9th retraction, for image duplication

Journal of Clinical InvestigationAlfredo Fusco, a researcher in Italy who has been under criminal investigation for scientific misconduct, has earned his ninth retraction.

Retraction number nine, by The Journal of Clinical Investigation, is for duplicating data from another publication — which has also faced questions on PubPeer about image manipulation, along with many other papers by Fusco.

The retraction note for “The RET/PTC-RAS-BRAF linear signaling cascade mediates the motile and mitogenic phenotype of thyroid cancer cells” explains that the journal is pulling the paper even though the authors claim that they can reproduce the data:
