Journal retracts paper by state senator (and former mathematician)

with 9 comments

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:

Cancer researcher logs 6 retractions, bringing total to 10

with 24 comments

Anil Jaiswal

A journal has retracted six papers by a cancer researcher at the University of Maryland in Baltimore, bringing his total to 10.

The retractions cite an investigation by the university, and detail problems ranging from duplicated images, to tweaking an image to conceal particular bands, to including unreliable data.

Three of the papers had already been flagged by the journal with expressions of concern. The last author on all the papers is Anil Jaiswal, a professor in the pharmacology department. He has issued four previous retractions.

Bruce Jarrell, the Chief Academic and Research Officer and Senior Vice President at the University of Maryland, told us at least two more retractions are forthcoming:

“Crucial experiments” missing from retracted plant study

without comments

A 2016 study was retracted from a Frontiers journal after editors realized the authors had omitted experiments that didn’t support the hypothesis. 

Gearóid Ó Faoleán, ethics and integrity manager at Frontiers, which publishes Frontiers in Plant Science, told us:

In accordance with our complaints protocol, the Field Chief Editor led the investigation that resulted in the decision to retract the paper.

EMBO journals retract figures in two papers missing source data

without comments

Journals published by the European Molecular Biology Organization (EMBO) have retracted a handful of figures in two papers with the same last and first authors.

After some figures in the 2005 and 2007 papers were flagged on PubPeer and the authors couldn’t provide the original data, the journals decided to retract parts of the papers, since other data supported the remaining conclusions, according to the Head of Scientific Publications at EMBO.

The partial retractions are labeled as corrigenda by the journals. Earlier this year, the U.S. National Library of Medicine (NLM) announced it would be classifying partial retractions as errata, noting they had been used so rarely by journals.

Both lengthy corrigenda (also reported by Leonid Schneider) contain statements from the authors and the editors. The statements from the authors provide detailed explanations about the problems with the figures in question; here’s an excerpt from the editor’s statement in The EMBO Journal corrigendum: Read the rest of this entry »

Karolinska requests retraction of 2014 Macchiarini paper

without comments

Paolo Macchiarini

It has been a tough couple of years for surgeon Paolo Macchiarini, once lauded for pioneering a groundbreaking procedure to transplant tracheas.

After a series of documentaries prompted his former employer, Karolinska Institutet (KI), to reopen a misconduct investigation against him, KI has today released one verdict regarding a 2014 Nature Communications paper: guilty.

KI said it is contacting the journal to request a retraction of the paper, which has already been flagged with an expression of concern.

Here’s more from a release from the institution: Read the rest of this entry »

Entomology journal retracts 2016 study with flawed analyses

with one comment

journal-of-medical-entomologyAn entomology journal has issued its first retraction during the current editor’s nearly 30-year tenure — for a 2016 study with serious flaws in the analyses. 

After the Journal of Medical Entomology (JME) published the study — about the identification of genes that enable an insect to detect odors — an outside researcher wrote a letter to the journal highlighting flaws in the paper. The journal then asked the authors to respond, and enlisted two additional peer reviewers to look into the study, the outside comment, and the authors’ response. They concluded the paper should be retracted.

William Reisen — the journal’s editor-in-chief from the University of California, Davis — said the journal believes the errors were unintentional and there was no fraud on the authors’ part. He added: Read the rest of this entry »

Researchers retract paper after they run out of breast milk

without comments

ejcn

If you think something is amiss with your data, running an experiment again to figure out what’s going on is a good move. But it’s not always possible.

A team of researchers in Seoul recently found themselves in a bind when they needed to check their work, but were out of a key substance: breast milk.

The shortage led them to the retract their 2016 paper on a micronutrient found in breast milk that helps protect infants’ retinas. “Association between lutein intake and lutein concentrations in human milk samples from lactating mothers in South Korea,” was published online last spring in the European Journal of Clinical Nutrition. 

Here’s the retraction notice:

University of Tokyo opens investigation into retracted stem cell paper

without comments

KCCY_15_22_COVER.inddThe University of Tokyo is investigating a 2011 stem cell paper in Cell Cycle, recently retracted over irregularities in four figures.

The university has confirmed there is an investigation, but would not specify which paper it concerned; the corresponding author on the paper, however, confirmed to us that it is the focus of the investigation.

In the retraction notice, published Nov. 1, the journal wrote: Read the rest of this entry »

Former Stanford researcher up to 5 retractions for unreliable data

without comments

journal-of-memory-and-languageA psychology researcher formerly based at Stanford University has logged her fifth retraction due to unreliable results.

According to the notice in the Journal of Memory and Language, Sandra Lozano takes full responsibility for the retraction.

Apparently, the retraction has been in the works for eight years — and in that time, journals have retracted four other papers co-authored by Lozano.

A Stanford spokesperson told us: Read the rest of this entry »

Authors retract paper linking nuclear power to slow action on climate change

with 2 comments

climate-policyDo pro-nuclear energy countries act more slowly to curb the effects of climate change? That’s what a paper published in July in the journal Climate Policy claimed. But the hotly debated study was retracted last week after the authors came to understand that it included serious errors.

An August 22 press release about the original study has been retracted by the University of Sussex, and no longer appears on ScienceDaily. An archived version notes:   Read the rest of this entry »
