Our retraction notice count for Shigeaki Kato, number seven on our leaderboard, has grown to 38.

The former University of Tokyo endocrinologist recently earned another retraction, for a paper in Archives of Biochemistry and Biophysics that contained image manipulation. As we’ve noted before, Kato resigned from the university in 2012 as it investigated his work for misconduct; in 2013 a Japanese newspaper reported that the investigation had found 43 papers from his lab contained “likely altered or forged materials.”

In addition to the new retraction, we’ve dug up four others for Kato from the past few years, plus one correction. Two of the retraction notices mention an investigation at the University of Tokyo.

First, the retraction note for “Multiple co-activator complexes support ligand-induced transactivation function of VDR,” published in December:

NEJM corrects 3 papers after prominent cancer scientist left off credit for breakthrough

Screen Shot 2016-03-15 at 12.04.43 PMThe New England Journal of Medicine has corrected three highly cited papers to credit researchers who played a role in the work.

The papers describe a treatment in which engineered T cells fight leukemia, originally hailed as a “major advance” in the New York Times. Since the first paper appeared in 2011, co-author Carl June at the University of Pennsylvania has received more than $7 million in grants from the National Institutes of Health, according to MIT Technology Review. But according to a newly published correction, the three NEJM papers failed to note in the acknowledgement section that an important component of the experiments was supplied by researchers at St. Jude Children’s Research Hospital.

The correction, made 11 months after a request from co-author and Penn researcher David Porter, explains the contribution of the St Jude’s researchers:

Another paper by GM researcher pulled over manipulation concerns

Screen Shot 2016-03-14 at 11.52.18 AMA researcher who published findings questioning the safety of genetically modified organisms has lost a second paper following concerns of image manipulation.

Last week, the journal animal retracted a 2010 paper by Federico Infascelli, an animal nutrition researcher at the University of Naples, which claimed to find modified genes in the milk and blood of goats who were fed genetically modified soybeans. The retraction stems from an investigation that concluded the authors likely manipulated images, according to the note. Earlier this year, another journal retracted one of Infascelli’s papers that contained a duplicated figure.

In February, Italian paper La Repubblica (which we read with Google Translate) reported that the university found problems in three of his articles and issued a warning.

Here’s the retraction note for “Fate of transgenic DNA and evaluation of metabolic effects in goats fed genetically modified soybean and in their offsprings:”

“I am really sorry:” Peer reviewer stole text for own paper

cl_45_2

We’re sharing a relatively old retraction notice with you today, because it’s of a nature we don’t often see: A chemist apparently stole text from a manuscript he was reviewing.

In spring of 2009, Yi-Chou Tsai, a chemist at National Tsing Hua University in Taiwan, was reviewing a paper for Nature Chemistry. At the time, he’d asked a colleague to write a review article with him, so forwarded him the Nature Chemistry manuscript for reference. But some of that text ended up in their review paper,”Recent Progress in the Chemistry of Quintuple Bonds,” published in Chemistry Letters. 

Both papers were published in 2009; Chemistry Letters retracted the review the next year.

The retraction includes a statement from Tsai, who puts the blame on his co-author, Chih-Chieh Chang, also listed as affiliated with NTHU (we couldn’t find a webpage for him):

Desalination journal let a plagiarized paper — from the same journal — through its filter

1-s2.0-S0011916415X00130-cov150h

The editor of Desalination has retracted a paper that plagiarized from another article published in the same journal six years earlier. The papers describe desalination systems, of course.

This retraction happened on a relatively quick timeline: The paper, “An integrated optimization model and application of MEE-TVC desalination system,” was published online in June, and pulled in January.

Here’s the retraction note:

Algorithm paper retracted for “significant overlap” with another

1-s2.0-S0096300314X00044-cov150hA paper on a hybrid algorithm turned out to be a hybrid itself — some original data, plus some from a paper that the authors had published earlier.

According to the retraction note, the overlap was significant enough to pull it from the scientific record.

The retracted paper describes an algorithm that is the combination of a “genetic algorithm” and a “cultural algorithm”– which, as their names sort of suggest, focus on looking at a population of solutions, and the history of which kinds of solutions work, respectively. According to the abstract, results to optimization problems found with a hybrid algorithm are “more accurate and the fast convergence is obvious.”

The retraction note provides a few details about the nature of the duplication:

Journal retracts bioelectronics paper for lack of credit to collaborators

S09565663The list of co-authors on a paper about a “bioelectronic composite” was apparently too sparse.

According to its retraction note — posted at the request of the editor-in-chief and the corresponding author — the paper failed to include some of the collaborators.

The Biosensors & Bioelectronics paper looks at a protein complex that could function as part of a “bio-hybrid” device, like a sensor or a solar cell. It has been cited only by its retraction according to Thomson Reuters Web of Science.

What went wrong in allotting credit for the work pretty straightforward, according to the note for “Monolayers of pigment–protein complexes on a bare gold electrode: Orientation controlled deposition and comparison of electron transfer rate for two configurations.” Here it is in full:

Papers with simpler abstracts are cited more, study suggests

J informetricsResearch papers containing abstracts that are shorter and consist of more commonly used words accumulate citations more successfully, according to a recent study published in the Journal of Informetrics.

After analyzing more than 200,000 academic papers published between 1999 and 2008, the authors found that abstracts were slightly less likely to be cited than those that were half as long. Keeping it simple also mattered— abstracts that were heavy on familiar words such as “higher,” “increased” and “time” earned a bit more citations than others. Even adding a five-letter word to an abstract reduced citation counts by 0.02%.

According to Mike Thelwall, an information scientist at the University of Wolverhampton, UK, who was not a co-author on the paper: Continue reading Papers with simpler abstracts are cited more, study suggests

More retractions bring total to 7 for neuroscience pair, 2 more pending

JOCNAuthors have retracted two papers about visual perception and working memory from the Journal of Cognitive Neuroscience, after the first author admitted to falsifying or fabricating data in four other papers.

The authors have requested another two retractions, as well, which will bring the total for Edward Awh and his former graduate student David Anderson to nine retractions. (Earlier in 2015, they lost a paper due to an error in the analytic code, which Awh told us was unrelated to the misconduct.)

The retraction notice attached to both articles cites a 2015 settlement agreement between the Office of Research Integrity and first author Anderson (the “respondent”), who admitted to misconduct while working as a graduate student in the lab of Awh at the University of Oregon in Eugene. Since then, “additional problems” were discovered in the newly retracted articles, such as removed data points.

Awh, who has since moved to the University of Chicago, sent us a lengthy statement, explaining the concerns about each article: Continue reading More retractions bring total to 7 for neuroscience pair, 2 more pending

Researchers’ productivity hasn’t increased in a century, study suggests

Screen Shot 2016-01-19 at 10.50.25 AMAre individual scientists now more productive early in their careers than 100 years ago? No, according to a large analysis of publication records released by PLOS ONE today.

Despite concerns of rising “salami slicing” in research papers in line with the “publish or perish” philosophy of academic publishing, the study found that individual early career researchers’ productivity has not increased in the last century. The authors analyzed more than 760,000 papers of all disciplines published by 41,427 authors between 1900 and 2013, cataloged by Thomson Reuters Web of Science.

The authors summarize their conclusions in “Researchers’ individual publication rate has not increased in a century:”
