Molecules has pulled a 2010 article by a trio of chemists from Tunisia who tried — and succeeded, for a while, at least — to publish the same data twice. The article was titled “An Expeditious Synthesis of [1,2]Isoxazolidin-5-ones and [1,2]Oxazin-6-ones from Functional Allyl Bromide Derivatives.” And indeed it was expeditious. Here’s the notice: Continue reading A tale of two notices as Tunisian chemists lose two papers for duplicated data

Asking for a retraction was “an overbearing response, though I agree that the student screwed up big time”
Just two months after a PhD student at King Fahd University of Petroleum and Minerals in Saudi Arabia published a paper in August without the knowledge of his co-author, a professor at the university, the paper was retracted by Cellulose.
Here’s the notice for “Corrosion protection of steel sheets by chitosan from shrimp shells at acid pH,” by graduate student Ubong M. Eduok and professor Mazen M. Khaled (well, not really by Khaled): Continue reading Asking for a retraction was “an overbearing response, though I agree that the student screwed up big time”
Authors retract two spectroscopy papers when follow-up results don’t match
The authors of two spectroscopy papers in Royal Society of Chemistry journals have retracted them.
Here’s the notice for “Determination of silk fibroin secondary structure by terahertz time domain spectroscopy” (free, but requires sign-in) in Analytical Methods, which is almost identical to this notice in Analyst: Continue reading Authors retract two spectroscopy papers when follow-up results don’t match
Student denied credit, math article retracted
A math paper in the Journal of Inequalities and Applications has been retracted after it was discovered the authors had included a student’s work without acknowledging her.
One of the authors, however, told us it was an honest mistake, and that the editor pushed for retraction instead of correction “to protect this journal and its impact factor.”
Here’s the notice for “On the Kirchhoff matrix, a new Kirchhoff index and the Kirchhoff energy”: Continue reading Student denied credit, math article retracted
Quantum physics paper pulled for “serious theoretical errors,” notice accidentally paywalled
A paper on photonic quantum walks has been retracted over a theoretical disagreement.
The notice is also paywalled, which the editorial director has assured us is a mistake that is being corrected.
We sent the COPE guidelines on retraction to the American Physical Society, which publishes Physical Review Letters. Editorial director Dan Kulp told us the paywall was the unintentional consequence of a web redesign, and that they are in the process of restoring public access to “all Errata-types, including Retractions.”
Here’s the rest of his statement: Continue reading Quantum physics paper pulled for “serious theoretical errors,” notice accidentally paywalled
“Several scientific errors” sink physics paper after rewrite opportunity
We don’t love this somewhat incoherent retraction for a paper on coherent states, although luckily the publisher was prompt with telling us a little more about what happened.
On October 2, a 2008 physics paper, “Generation of a superposition of coherent states in a resonant cavity and its nonclassicality and decoherence,” was retracted for “several scientific errors,” pointed out by a comment published in the same journal. The original authors rewrote the paper, but it was not up to the standards of Canadian Journal of Physics, so it was rejected, and the original was retracted.
Here’s the notice: Continue reading “Several scientific errors” sink physics paper after rewrite opportunity
Is it better to retract a paper, or publish a letter calling the conclusions “unphysical?”
Sometimes publishers and authors decide it’s easier to retract a paper than leave it up for discussion by other scientists.
That seems to be the case here: The authors of a paper in Langmuir retracted it in September for a math mistake, but not before the journal refused to publish a comment criticizing the publication.
Here’s the notice for “Drainage of a thin liquid film between hydrophobic spheres: Boundary curvature effects:” Continue reading Is it better to retract a paper, or publish a letter calling the conclusions “unphysical?”
Blatant plagiarism sinks paper (and earns a sabbatical!) for mathematician

You know it’s a good one when it makes it onto the Wikipedia page for “scientific misconduct.”
On April 21, the International Journal of Pure and Applied Mathematics retracted two 2008 papers by scientist Alexander Spivak of Holon Institute of Technology in Israel. In September, the journal updated the notice to explain why: The papers both contained copy/pasted chunks from a 2001 paper by Spivak’s post-doc boss at Tel Aviv University, Zeev Schuss, and two other authors.
The tipster seems to have been Schuss himself, who told us about his role in the unravelling of the fraud: Continue reading Blatant plagiarism sinks paper (and earns a sabbatical!) for mathematician
Doing the right thing: Particle physicists pull paper after equation collides with the truth
Three physicists at Imperial College London have retracted a paper on Coulomb collisions, a kind of fender bender between two charged particles, after realizing their equations were written wrong.
The mistake resulted in an erroneous conclusion about the strength of the collisions.
Here’s the notice for “Effects of Large-Angle Coulomb Collisions on Inertial Confinement Fusion Plasmas”: Continue reading Doing the right thing: Particle physicists pull paper after equation collides with the truth
Oops: Elsevier journal publishes paper citing paper it promised to retract two months ago
Journal publishers can be agonizingly slow when it comes to officially retracting a paper.
Here’s a prime example of the consequences of that bureaucratic foot-dragging: Ten months after being told that Fazlurrahman Khan had fabricated his data, and two months after announcing two of Khan’s papers would be retracted from two of its journals, Elsevier still has not retracted either paper.
Worse, at least one of the papers, “Degradation of 2,4-dinitroanisole (DNAN) by metabolic cooperative activity of Pseudomonas sp. strain FK357 and Rhodococcus imtechensis strain RKJ300,” in the journal Chemosphere, has been cited since the announcement was made. In fact, the paper was published in Journal of Hazardous Materials, the Elsevier journal that is dragging its feet retracting another of Khan’s papers, “Aerobic degradation of 4-nitroaniline (4-NA) via novel degradation intermediates by Rhodococcus sp. strain FK48.”
Jim Spain, in whose lab Khan worked at Georgia Tech, reached out to us to express his concerns with this timeline: Continue reading Oops: Elsevier journal publishes paper citing paper it promised to retract two months ago
