More retractions, errata discovered for nursing researcher

Since our recent coverage about a university investigation that led to multiple retractions for nursing researcher Moon-fai Chan, we’ve been alerted to a few more retractions and errata. His total is now at six retractions and four errata. Some of our finds were published this year, and some are a few years old. Most are due to duplication; … Continue reading More retractions, errata discovered for nursing researcher

Plagiarism was “not an intentional act,” says first author of retracted TB paper

A 2013 review article about tuberculosis is being retracted for “unacknowledged re-use of significant portions of text” from another article, which the first author said wasn’t intentional. Sayantan Ray, based at Medical College and Hospital, Kolkata in India, told us that “most of the unchanged text” is present in sections written by junior co-authors. Since there doesn’t … Continue reading Plagiarism was “not an intentional act,” says first author of retracted TB paper

University investigating duplicated images in retracted paper

The authors of a Cell Metabolism paper are pulling it after discovering blot images that “appear more than once in independent and unrelated experiments.”  Just how the duplication occurred in the 2009 paper — about transcription of mitochondrial DNA — remains a mystery, the authors note: …the reasons for the errors are still under investigation… Meanwhile, … Continue reading University investigating duplicated images in retracted paper

Failure to reproduce key experiments retracts cancer study

A group of Chinese cancer researchers has retracted a paper in Medical Oncology after they discovered that “several key experiments” were not reproducible. The paper, “Decreased Warburg effect induced by ATP citrate lyase suppression inhibits tumor growth in pancreatic cancer,” was published in March.

Authors defend publishing clinical trial six times, even as they earn two more retractions

In August, we reported on a clinical trial on hundreds of hypertensive patients that was published six times. Now, copies published in Expert Opinion on Drug Safety and Journal of the American Society of Hypertension (JASH) have been retracted, making for a total of three retractions for the group of papers. The authors have defended the papers as being decidedly … Continue reading Authors defend publishing clinical trial six times, even as they earn two more retractions

Is less publishing linked to more plagiarism?

Countries that publish less science appear to “borrow” more language from others than other, more scientifically prolific countries, according to a new small study. Using a novel approach of comparing a country’s total citations against its total published papers (CPP), the authors categorized 80 retractions from journals in general and internal medicine. This is a … Continue reading Is less publishing linked to more plagiarism?

Weekend reads: FDA nominee authorship questions; low economics replication rates

The week at Retraction Watch featured a mysterious retraction from PLOS ONE, and a thoughtful piece by a scientist we’ve covered frequently on where we went wrong in that coverage. Here’s what was happening elsewhere:

Journal bans authors of duplicated asthma paper

A common ailment known as duplication has taken down a paper about a common fungus and asthma. Aspergillus spores are often ubiquitous yet harmless, but can irritate people whose lungs aren’t in top working order. Duplication, on the other hand, is more universally deadly. The editors of The Pan African Medical Journal told us that, in addition to the retraction, there … Continue reading Journal bans authors of duplicated asthma paper

Mystery: PLOS One seeks investigation after publishing two papers with “substantial overlap”

PLOS One has retracted one of two cancer papers with “substantial overlap” that were reviewed simultaneously by different editors. This one’s a bit of a mystery — neither of the papers share an author, and no authors share institutions. Once the editors discovered the overlap, they contacted the authors. One group of authors provided the requested … Continue reading Mystery: PLOS One seeks investigation after publishing two papers with “substantial overlap”

Investigation ends in 6th retraction for Voinnet

A sixth paper co-authored by plant researcher Olivier Voinnet has been retracted by PLOS Pathogens “following an investigation into concerns.” The investigation found “several band duplications” in one figure provided by fifth author, Patrice Dunoyer, who took it from “the Master thesis of a former student working under his supervision, without the prior consultation or consent … Continue reading Investigation ends in 6th retraction for Voinnet
