Another image falsification retraction for Emory heart researchers

jbc1112coverA group of authors from Emory University, has lost another paper for image manipulation, bringing their total to at least four. What makes this particularly interesting is that the main actor in the figure fakery, Lian Zuo, does not appear to have been involved this time.

Zuo, you may recall, was cited in multiple retraction notices back in 2011 after Emory investigators concluded that he appeared to have been fabricating figures. But, one of the notices, from Circulation Research, raised the possibility that someone else was implicated, too: Continue reading Another image falsification retraction for Emory heart researchers

Third retraction appears for orthopedic surgeon involved in investigation, lawsuits

orthopedic reviewsIn July, we reported on the unfortunate math of Harish Hosalkar, a San Diego orthopedic surgeon who was at the center of an institutional investigation into the integrity of his data, two lawsuits and three retractions.

At the time, we were waiting on the third retraction, in the journal Orthopedic Reviews. It has now arrived.

The article was titled “Open reduction and internal fixation of displaced clavicle fractures in adolescents,” and Hosalkar wrote it with Gaurav Parikh, James D. Bomar and Bernd Bittersohl. Continue reading Third retraction appears for orthopedic surgeon involved in investigation, lawsuits

Correction by punctuation? PNAS fixes paper by putting quotes around plagiarized passages

PNAScover1113PNAS has a curious correction in a recent issue. A group from Toronto and Mount Sinai in New York, it seems, had been rather too liberal in their use of text from a previously published paper by another researcher — what we might call plagiarism, in a less charitable mood.

To paraphrase Beyoncé: If you like it, better put some quotation marks around it. But we’re pretty sure she meant before, not after, the fact.

The article, “Structural basis for substrate specificity and catalysis of human histone acetyltransferase 1,” had appeared in May 2012, in other words, some 17 months ago. It has been cited twice, according to Thomson Scientific’s Web of Knowledge.

As the notice states: Continue reading Correction by punctuation? PNAS fixes paper by putting quotes around plagiarized passages

JACS retracts polymer paper over data concerns

jacsat_v135i044.inddThe Journal of the American Chemical Society has retracted a 2009 paper on ethylene polymerization after the authors said they were unable to replicate their findings.

The article, “Bimetallic Effects for Enhanced Polar Comonomer Enchainment Selectivity in Catalytic Ethylene Polymerization,”came from the lab of Tobin Marks, a highly decorated — and grant-and-royalty-generating — chemist at Northwestern University.

Nature yanks controversial genetics paper whose co-author was found dead in lab in 2012

naturecover1113Nature has retracted a controversial 2012 paper by a group from Johns Hopkins University which has been the subject of a protracted public dispute.

The article, “Functional dissection of lysine deacetylases reveals that HDAC1 and p300 regulate AMPK,” came from the lab of Jef Boeke,  a celebrated biochemist. But a former lab member, Daniel Yuan, who was fired by Hopkins in late 2011 after 10 years at the institution, had repeatedly raised questions about the validity of the findings. Those concerns eventually made their way into the Washington Post, prompting this response from the university.

Two detailed retraction notices correct the cardiology record

jaccTwo American College of Cardiology conference abstracts published earlier this year in the Journal of the American College of Cardiology (JACC) have been retracted, one because the authors were actually measuring something other than what they reported, and the other because newer software invalidated the results.

Here’s the notice for “Worsening of Pre-Existing Valvulopathy With A New Obesity Drug Lorcaserin, A Selective 5-Hydroxytryptamine 2C Receptor Agonist: A Meta-Analysis of Randomized Controlled Trials” by Hemang B. Panchal, Parthav Patel, Brijal Patel, Rakeshkumar Patel, and Henry Philip of East Tennessee State University: Continue reading Two detailed retraction notices correct the cardiology record

Last week, we reported that some of the authors of a 2010 paper in the BMJ claiming to have identified Henry IV’s head thought the study should be retracted based on new evidence. Some of the other authors have now responded to that call for retraction, which appeared on the BMJ’s site alongside the paper.

Philippe Charlier, the corresponding author of the original paper, and five of the original paper’s 15 co-authors conclude after reviewing the evidence that

He said, she said: Journal of Neuroscience expresses concern, but doesn’t pursue investigation

j neuroscienceThe Journal of Neuroscience‘s retraction notices often give us plenty to chew on, and a new Expression of Concern does the same.

In the notice — for a 16-year-old paper — the journal notes three cases of what certainly sounds like image manipulation, but carefully avoids calling it that: Continue reading He said, she said: Journal of Neuroscience expresses concern, but doesn’t pursue investigation

Image manipulation leads to fifth retraction for plant research group

plant scienceA plant scientist at the Colorado State University has retracted a fifth paper.

Here’s the notice for “Influence of ATP-binding cassette transporters in root exudation of phytoalexins, signals, and in disease resistance, a paper originally published in July 2012:

The Journal, Chief Editor and the Authors wish to retract the Original Research article cited above in its entirety. Based on information reported after publication, this article was found to have images that were inappropriately manipulated (Figure 1B: actin panel; Figure 6A: PR1, PR5; Figure 6B: AtATH6, AtATH10). The authors and the journal regret the errors and regret any inconvenience to the readers of Frontiers in Plant Science.

The last author of the now-retracted paper, Jorge Vivanco, has had four previous retractions, including one in Nature. He tells us: Continue reading Image manipulation leads to fifth retraction for plant research group

Off with his paper! Some authors want to retract claim to have identified Henry IV’s head

The BMJ is well-known for its annual Christmas issue, which New York Times medical correspondent Lawrence Altman calls

a lighter and sometimes brighter side of medicine, publishing unusual articles that vary from simply amusing to bizarre to creative or potentially important.

The 2010 issue was no exception, featuring a paper called “Multidisciplinary medical identification of a French king’s head (Henri IV)” in which: Continue reading Off with his paper! Some authors want to retract claim to have identified Henry IV’s head
