More than two thousand researchers have signed a petition to boycott a new Nature journal over the fact it will be available only by subscription.
The new journal — Nature Machine Intelligence, about machine learning — plans to charge readers for access, unlike most other journals in the field. The researchers who signed the petition have pledged not to submit their work to the new journal, and will decline to review or edit papers for it, as well.
Most journals published by Nature Publishing Group are available only by subscription — but that doesn’t work for the machine learning community, the signatories argue:

Decades ago, unbeknownst to each other, two chemists were independently working on a screening approach to identify new potential drugs. Both published papers about the technique around the same time. So now, when scientists write papers that cite the technique, who should get credit for discovering it?
Decades later, that question still hasn’t been answered — and the researchers continue to argue, this time over one’s decision not to cite the other’s work.
More than 30 years ago, Árpád Furka—now retired from Eötvös Loránd University in Budapest—developed an approach he says has had “outstanding importance” in drug development. The technique, called split-mix synthesis, made it possible to synthesize and screen millions of peptides at once, instead of one by one. Furka patented the method in 1982, presented an abstract in 1988, and published a paper in 1991. Continue reading Chemists duke it out over who was first to discover a 30-year-old technique
A researcher whose work on the use of nanomaterials has been heavily scrutinized on PubPeer — with one critic alleging a paper contained “obviously fabricated” images — has lost eight papers. [Editor’s note: See update below.]
The eight articles — seven from Biosensors and Bioelectronics and one from Analytica Chimica Acta, both published by Elsevier — all cite issues related to duplications, and conclude with some version of the following:

Recently, a rash of news outlets posted concerns that canned tuna and other products may contain potentially dangerous levels of zinc. They were all wrong.
News outlets such as The Daily Mail and The Sun reported findings from a recent study, which showed that canned foods such as tuna may contain 100 times the daily limit of zinc — raising concerns about how such huge doses of the mineral could be causing digestion problems. The last author of the study told Retraction Watch the paper is going to be retracted, because the authors made a fundamental error calculating the amount of zinc present in canned foods.
Last week, the UK’s biggest health website NHS Choices posted a critique of the paper, in which they recalculated the levels of zinc present in canned foods:

A chemistry journal has retracted a nanoparticle paper following heavy outcry from readers, who alleged the paper contained signs of obvious manipulation.
After the paper appeared in 2017, one critic lamented it contained “obviously fabricated” images, and asked the journal to retract it. Another suggested the presence of one image merited “an instant lifetime ban.”
The first comment about the paper appeared on PubPeer three months ago; earlier this month, the journal ACS Biomaterials Science & Engineering retracted the paper.
Here’s the notice:

The authors of a highly cited 2016 research letter on a way to improve the efficiency of solar panels have retracted their work following “concerns about the reproducibility.”
Given the potential importance of the data, it would be nice to know what exactly went wrong, and why. However, the retraction notice doesn’t provide many details, and doesn’t even specify if the authors did indeed fail to reproduce the data.
The letter, titled “Graded bandgap perovskite solar cells,” was published in Nature Materials by a group out of the University of California at Berkeley and the affiliated Lawrence Berkeley National Laboratory. The 2016 article has been cited 16 times, according to Clarivate Analytics’ Web of Science, earning it the ranking of “highly cited.”
Berkeley heralded the findings in a press release as a “major advance” in the field of solar energy:

Here’s an unusual way to allege plagiarism: Do it in the reference list.
That’s what Brian Levine, a professor in the College of Information and Computer Sciences at the University of Massachusetts in Amherst, did when he came across a paper he wanted to cite but suspected of plagiarism. When Levine published his 2017 paper, he cited the paper in question as:
R.Rajan, “ Feasibility, Effectiveness, Performance and Potential Solutions on Distributed Content Sharing System [plagiarized],” Intl. J. Engineering and Computer Science, 5(1):15638–15649, Jan 2016 http://www.ijecs.in/ issue/v5- i1/30%20ijecs.pdf.
Levine’s paper, which explores a way of identifying perpetrators of online child pornography, provides no further details about the nature of the plagiarism or from what source the paper allegedly plagiarized. Continue reading Unusual: Author uses a reference list to accuse a paper of plagiarism
An engineering journal has retracted three 2016 papers. The reason: They had been cited too often.
Although the reason for the retractions may sound odd, the editor, Minvydas Ragulskis, told Retraction Watch he was concerned an author had engaged in citation manipulation. Specifically, Ragulskis explained that the majority of the citations came from papers at a 2017 conference on which one of the authors, Magd Abdel Wahab, was chair—raising suspicion that he had asked conference presenters to cite his work.
Almost three-quarters of papers that cited Wahab’s work originated from the conference, which “is large enough to assume a high probability for citation manipulation,” Ragulskis said. (Wahab, Professor and Chair of Applied Mechanics at Ghent University in Belgium, was not a co-author on the conference papers that cited his work.)

A researcher whose work has been heavily questioned on PubPeer has corrected a figure on a 2015 paper in Talanta — but the text of the correction doesn’t match the actual changes.
Recently, Rashmi Madhuri at the Indian Institute of Technology (Indian School of Mines) in Dhanbad corrected a 2015 paper about a diagnostic sensor that uses nanoparticles, noting that there was a “small error” in the legend describing figure 1. But the corrected image bears the same legend it had before, and instead swapped a panel of the figure that had been questioned on PubPeer.
Here’s another puzzling element to the story: Gary Christian at the University of Washington, one of the editors-in-chief of the journal, tells us he doesn’t “recall being aware of the corrigendum:”

A researcher has retracted a 2009 chemistry paper after discovering that a figure had been “inappropriately edited.”
According to the journal, a reader brought the images in question in Figure 1 to the editors’ attention last September. Timothy P. Lodge, distinguished professor at the University of Minnesota in Minneapolis — and editor of Macromolecules through December 2017 — told Retraction Watch:
