Scientists “wish to resign as co-authors:” Quantum dot paper retracted

chemcommChemical Communications has retracted a 2015 article by a group of researchers in China over concerns about fabricated data and an incredible shrinking list of authors.

The paper, “N, S co-doped graphene quantum dots from a single source precursor used for photodynamic cancer therapy under two-photon excitation,” was ostensibly written by nine researchers at the Collaborative Innovation Center for Marine Biomass Fiber, Materials and Textiles of Shandong Province, the Shandong Sino-Japanese Center for Collaborative Research of Carbon Nanomaterials, Laboratory of Fiber Materials and Modern Textiles, the Growing Base for State Key Laboratory at the  College of Chemical Science and Engineering at Qingdao University, and Mayo Clinic, in Rochester, Minn.

According to the abstract: Continue reading Scientists “wish to resign as co-authors:” Quantum dot paper retracted

Geology dust-up: Second sand paper swept away for duplication

GeomorphologyCiting an “abuse of the scientific publishing system,” the editors of Geomorphology have retracted a paper from a quartet of geologists in China for containing “significant similarity” to four other papers.

It is the second recent retraction for the group: In a loop of self-plagiarism, the Geomorphology paper was cited as a source of copied material in a retraction last month from Sedimentary Geology.

This most recent retraction is of a January 2014 paper, “The influence of sand bed temperature on lift-off and falling parameters in windblown sand flux,” analyzing the rise and fall of windblown sand based on the temperature of the sand bed.

Here is the full text of the notice:

Fluid mechanics article retracted with no explanation

JHeatTransf_ak7An article published earlier this year has been retracted from the  Journal of Heat Transfer. But the retraction notice gives no information about what was amiss.

The article is entitled “Neural Network Methodology for Modeling Heat Transfer in Wake Flow,” and the retraction notice, in full, reads: Continue reading Fluid mechanics article retracted with no explanation

Bully for you! Duplication earns demerit for school cruelty paper

Trauma-kashan3Archives of Trauma Research has retracted a 2014 paper on bullying by a group in Iran who appear to have been double-fisted in their approach to publishing.

The article, “Epidemiological Pattern of Bullying Among School Children in Mazandaran Province, Iran,” was written by researchers from Shahid Beheshti University of Medical Sciences, in Tehran. Its conclusions:

Different forms of bullying have a distinct nature and the epidemiological pattern indicates that bullying exists in the Iranian schools. Thus, the effective bullying prevention and appropriate intervention programs are recommended.

Here’s the notice:

Heart repair study retraction marks second for Mercer University researcher

BasicResCardio_ak12Authors of a study on cardiac repair after heart attack are retracting it from Basic Research in Cardiology because they used “the same samples… to represent two distinct groups on two occasions.”

We find the language of the retraction somewhat confusing, but to the best of our understanding it means that they compared apples to the exact same apples.

The study, published online in 2012, examined the mechanism behind the beneficial effects of a procedure called postconditioning in treating heart attacks. Here’s the retraction notice: Continue reading Heart repair study retraction marks second for Mercer University researcher

Weekend reads, part 2: Oldest-ever PhD; most embarrassing citation ever; blame the antibodies?

booksAs we noted Saturday, there was so much happening around the web last week that it made sense to break up Weekend Reads, especially since this is a holiday weekend in the U.S. and elsewhere. Here’s part 2: Continue reading Weekend reads, part 2: Oldest-ever PhD; most embarrassing citation ever; blame the antibodies?

Weekend reads: Gay canvassing study redux; editors fired; how the world’s biggest faker was caught

booksThis week at Retraction Watch was dominated by the Science same-sex marriage study, after we broke the news Wednesday morning that one of its authors had requested its retraction. (And crashed our servers in the process.) So the first section of this Weekend Reads will focus on pieces following up on that story:

But there was plenty more happening this week: Continue reading Weekend reads: Gay canvassing study redux; editors fired; how the world’s biggest faker was caught

Chip slip: Irreproducibility erases computer memory paper

nanoscaleResearchers at the Chinese Academy of Sciences have retracted a paper in Nanoscale about an experimental computer chip after they were unable to recreate their published results.

“We retract this article to avoid misleading readers and intend to undertake further tests to confirm our previous results,” they write in the notice.

The scientists are working on developing a chip that uses resistive random-access memory, which allows a huge amount of information to be stored in a tiny package and accessed quickly while using very little power. A number of companies are working on the technology, but none have successfully commercialized it.

Here’s the notice for “High uniformity and improved nonlinearity by embedding nanocrystals in selector-less resistive random access memory” (free, but requires login): Continue reading Chip slip: Irreproducibility erases computer memory paper

“The first author assumes all responsibility:” Malaria vaccine article retracted for image manipulation

InfectAndImmunAuthors of a 2012 article in Infection and Immunity investigating a malaria vaccine strategy are retracting it because it “contains several images that do not accurately reflect the experimental data.”

The paper, “Fine Specificity of Plasmodium vivax Duffy Binding Protein Binding Engagement of the Duffy Antigen on Human Erythrocytes,” has been cited 9 times, according to Thomson Scientific’s Web of Knowledge.

The retraction notice places the blame for the image shenanigans squarely on the first author, Asim Siddiqui, who is currently listed on LinkedIn as a faculty member at the College of Applied Medicine at King Saud University in Saudi Arabia.

Here’s the notice: Continue reading “The first author assumes all responsibility:” Malaria vaccine article retracted for image manipulation

What should an ideal retraction notice look like?

logoHave you seen our “unhelpful retraction notices” category, a motley collection of vague, misleading, and even information-free entries? We’d like to make it obsolete, and we need our readers’ help.

Here’s what we mean: Next month, Ivan will be traveling to Rio to take part in the World Conference on Research Integrity. One of his presentations is a set of proposed guidelines for retraction notices and their dissemination that we hope will inform publishing practices and severely limit the number of entries in our “unhelpful retraction notices” category. In September, for example, we announced that our guidelines would be linked from PRE-val, which “verifies for the end user that content has gone through the peer review process and provides information that is vital to assessing the quality of that process.”

Here’s a draft of our proposed guidelines, which include many of the items recommended by the Committee on Publication Ethics and the International Committee of Medical Journal Editors: Continue reading What should an ideal retraction notice look like?
