Journal retracting at least nine articles by education researcher

JAASEPA investigation in Singapore has failed to turn up primary data that formed the basis for 11 papers from one author about special education.

In addition, a forensic investigation at Noel Chia’s institution — the National Institute of Education in Singapore, part of Nanyang Technological University (NTU) — suggested that some signatures providing parental consent might not be authentic. The investigation was also unable to authenticate the Malaysia-based organization Chia said collected the data on his behalf.

Nine of the papers appear in the Journal of the American Academy of Special Education Professionals (JAASEP), which has declared it plans to retract every article Chia has ever published with them (we’ve counted an additional nine papers).

Much of the information we know about the case stems from the unusually detailed — 3,000 word — retraction notice from JAASEP:

How does Jeremy Berg plan to address reproducibility in Science?

The former director of the National Institute of General Medical Sciences at the U.S. National Institutes of Health has a new job. On July 1st, biochemist Jeremy Berg will take the helm as the editor-in-chief of Science. He’s currently the associate senior vice chancellor for science strategy and planning in the health sciences at the University of Pittsburgh. We spoke to him about challenges he’ll be facing in his new role: treating science’s replication problem, boosting transparency, and making papers as widely available as possible.  

You told us in an earlier conversation that diagnosing and treating science’s replication problem is major issue in publishing. Can you give us some specifics about how you plan to address it at Science? Continue reading How does Jeremy Berg plan to address reproducibility in Science?

Authors retract surgery study that claimed to be randomized but wasn’t

spine-coverThe authors of a study about spinal fusion surgery have retracted it after realizing the cohort study was described as a prospective, randomized trial. 

The last author told us he believed the incorrect wording was added to the paper — and the title — by accident. Even though he said the journal Spine suggested correcting it, the authors chose to retract the paper entirely.

The abstract of the study describes the design as a:

Prospective, randomized, controlled trial.

But according to the retraction notice for “Prospective, randomized, controlled trial of silicate-substituted calcium phosphate versus rhBMP-2 in a minimally invasive transforaminal lumbar interbody fusion,” the abstract was not accurate:

Misidentified cell line fells cancer paper

Screen Shot 2016-04-15 at 2.52.06 PMResearchers have retracted a paper about a new molecular target for cancer after realizing they had mistaken the identity of their cell line.

It’s all too easy to mix up cell lines, so we see plenty of retractions for that reason — and, according to an expert in the area, many more cases lurk uncorrected in the literature.

The retraction notice for “Knockdown of tumor protein D52-like 2 induces cell growth inhibition and apoptosis in oral squamous cell carcinoma” in Cell Biology International explains the authors’ perspective on this case:

Environmental group alleges scientific fraud in disputed methane studies

icn-logoNote: We are reprinting below an article originally published at InsideClimate News.

The inspector general of the U.S. Environmental Protection Agency has been asked to examine whether a significant recent study of greenhouse gas emissions from oil and gas fields was technically flawed—and whether researchers brushed aside concerns that methane pollution was being understated.

The emission of methane, a much more potent greenhouse gas in the short term than carbon dioxide, has proven difficult to measure. The latest complaint is a volley in a long-running skirmish among academics, advocacy groups and regulators over how tightly methane should be regulated.

On Wednesday, a North Carolina environmental advocacy group, NC Warn, alleged that this dispute has risen to the level of fraud. Continue reading Environmental group alleges scientific fraud in disputed methane studies

Columbia investigation reveals researcher faked data — and a degree

InnateImmunityA researcher faked data and a masters degree, according to an investigation by Columbia University.

He’s also earned his fourth retraction. The new notice, along with one we’ve uncovered from 2014, provide some information on the extent of the deception of Robert Frumento, who left Columbia a decade ago, around the time that the now-retracted papers were published.

Here’s the new retraction notice:

Author denies accusations of blatant duplication

NPGTwitter is abuzz today over allegations that a recent paper in Scientific Reports contains a blatant example of duplication.

According to the allegations, a group of researchers in Malaysia have used the same four images to represent some 30 cells at different stages of cell death. One researcher has even suggested the allegedly doctored images appear in three different papers.

Is this a manipulated image? See for yourself:

Pharmacology journal pulls paper for “insufficient scientific quality;” authors disagree

Frontiers in PharmacologyAgainst the authors’ wishes, a pharmacology journal has retracted a paper after receiving two messages questioning the “soundness of the experimental results.”

The editors of the journal, Frontiers in Pharmacology, issued an expression of concern about the paper in April 2016, and investigated it following the allegations. According to the retraction notice, the authors disagree with the retraction.

Here’s the retraction notice for the paper: Continue reading Pharmacology journal pulls paper for “insufficient scientific quality;” authors disagree

Three more papers felled by suspected fake reviews

Food Processing and Preservation

So far, we’ve counted more than 300 papers that have been retracted after editors suspected the peer-review process had been compromised — and we’re adding three more to the list.

Editors of the Journal of Food Processing and Preservation became suspicious of the three papers after discovering similarities in reports from supposedly different reviewers. When they were unable to verify the identities of the reviewers, they pulled the papers.

An editor told us that he thinks the reviewer identities were fabricated entirely (as opposed to stolen):

“All co-authors are honorary:” Team earns fifth retraction

Movement DisordersA team of researchers from Japan has earned a fifth retraction, after co-authors told the journal that they did not participate in much of the paper.

Yoshihiro Sato, listed at Mitate Hospital, is the only author of the paper who was not “honorary,” the managing editor of the journal confirmed. He and the same co-authors recently lost three other papers about preventing hip fractures for “concerns regarding data integrity” and authorship issues — one of those papers, published in JAMA, specified that Sato was responsible for the data. All four authors were also included in a retraction last year of a paper with “concerns about the underlying data;” there, too, Sato said his co-authors were named “for honorary reasons.”

Here’s the retraction notice for “Alendronate and vitamin D2 for prevention of hip fracture in Parkinson’s disease: A randomized controlled trial,” published in Movement Disorders:
