“Part of a paper that had already appeared”: Materials paper pulled for plagiarism

1-s2.0-S1387181115X00035-cov150hMicroporous and Mesoporous Materials has retracted a 2015 paper after it was discovered the authors “have plagiarized part of a paper that had already appeared.”

The paper, “Ionic liquid assisted synthesis of flexible and super-hydrophobic porous gels,” described the synthesis of a form of flexible aerogels “through a facile one-pot preparation,” according to the abstract. According to Thomson Scientific’s Web of Knowledge it has been cited zero times.

Here is the retraction note, in full:

Cell biologist Hanna issues two errata; images mysteriously disappear from Imgur

Cell biologist Jacob Hanna, the highly cited stem cell researcher currently at the Weizmann Institute of Science,  has posted a long erratum for a 2005 paper in Blood for “inadvertent mistakes,” among other issues; soon after, Hanna’s team issued another erratum for a 2009 Cell Stem Cell paper.

There’s more to tell: Last month, commenters on PubPeer noticed that images from at least 10 of the research papers Hanna coauthored in seven journals — that commenters had posted on the image hosting website Imgur and linked to on PubPeer — had been deleted.

Imgur did not confirm whether these specific images had been deleted, but told Retraction Watch:

Half of anesthesiology fraudster’s papers continue to be cited years after retractions

ethicsIn yet more evidence that retracted studies continue to accrue citations, a new paper has shown that nearly half of anesthesiologist Scott Reuben’s papers have been cited five years after being retracted, and only one-fourth of citations correctly note the retraction.

According to the new paper, in Science and Engineering Ethics: Continue reading Half of anesthesiology fraudster’s papers continue to be cited years after retractions

Lancet journal removes Buddha cover art following protest

Lancet inf disThe Lancet Infectious Diseases has removed a cover illustration of the Buddha contemplating a mosquito from its June, 2015 issue — a complement to a paper about malaria treatment in Cambodia — after receiving emails from readers who protested the depiction of the statue in a non-religious context.

After publishing the cover, the journal received “several emails” protesting the image, such as this one from Arjuna P R Aluwihare:

Macchiarini co-author objects to investigation’s misconduct verdict

One of Paolo Macchiarini’s co-authors on a 2011 Lancet paper describing an allegedly groundbreaking procedure to transplant an artificial trachea seeded with stem cells is objecting to a recent investigation that concluded Macchiarini had committed misconduct.

Ola Hermanson, who studies neural stem cells at Karolinska Institutet, argued in a report dated June 29 that the investigation contained “serious flaws and formal errors.”

Hermanson’s lengthy response (uploaded here except for supporting emails) is to the findings of an external review of allegations about Macchiarini’s work, conducted by Bengt Gerdin, of Uppsala University. In regards to the 2011 Lancet paper, Gerdin’s investigation found:

A tale of two journals: Elsevier retracts paper after publishing it in the wrong journal

EMIf you happen to pick up this month’s issue of Economic Modelling, there’s a little surprise on page 307—blank pages. Publisher Elsevier has retracted a paper from that space because it “inadvertently published” the paper in the journal. In fact, Elsevier meant to include the paper in the pages of its other journal, Energy Economics.

The paper, “An Approach to Computing Marginal Land-Use Change Carbon Intensities for Bioenergy in Policy Applications,” is most assuredly not about economic modeling. Rather, it describes an approach for assessing carbon emissions from the production of bioenergy crops.

Here’s the retraction notice: Continue reading A tale of two journals: Elsevier retracts paper after publishing it in the wrong journal

Lancet Oncology updates conflicts of interest statement for cancer-cell phone paper

lanoncThe Lancet Oncology is correcting a 2011 article about the cancer risks of radiofrequency electromagnetic fields, such as those from cell phones, to clarify information about potential conflicts of interest for one of the experts who was involved in its preparation.

The assessments appeared as a monograph for the International Agency for Research on Cancer (IARC).

However, after the 2011 paper “Carcinogenicity of radiofrequency electromagnetic fields” appeared, a reader raised allegations of conflicts of interest among its participants, which sparked a reconsideration of their disclosures.

The correction concerns the conflicts of interest for Niels Kuster of the Swiss Federal Institute of Technology in Zurich, also a board member of the non-profit IT’IS foundation.

Kuster told Retraction Watch he disclosed everything upfront:

Food fight: Animal nutrition author disputes two retractions

LSA pair of animal nutrition researchers in India have now had a second paper on the nutritional value of a fungal treatment for wheat straw retracted, and one of the authors is very unhappy about it.

M.S. Mahesh of the National Dairy Research Institute at Deemed University claims a co-author issued “abusive letters” to an editor of the journal where the first paper was retracted (which said co-author denies), and that editors responsible for the second retraction removed the paper “unscientifically and unethically.”

The second paper, in Livestock Science, describes the treatment of wheat straw, a wheat by-product, with a fungus in an effort to improve the nutritional worth of the straw. It has a similar title, subject, and conclusions to those of a 2013 paper from the journal Tropical Animal Health and Production, which was retracted because the authors “had no permission to use the data presented in the Table 1.”

We described that earlier retraction from TAHP, and the similarity with this most recently retracted paper, in a post from early last year.

Here is the LS retraction notice for “Nutritional evaluation of wheat straw treated with white-rot fungus Crinipellis sp. RCK-SC in Sahiwal calves”: Continue reading Food fight: Animal nutrition author disputes two retractions

Plagiarism identified in computer face recognition paper

A paper about computerized facial recognition has been pulled because “most of the contents of this article is plagiarized from an article under consideration elsewhere,” according to the retraction statement.

Applications of computer face recognition include surveillance and criminal identification. The authors propose a new method for picking out facial features in the original 2013 article, “Pose invariant face recognition using biological inspired features based on ensemble of classifiers.”

The retraction note offers few details on what went wrong. Here it is, in full:
