Three retractions for Oregon neuroscience student investigated by ORI

without comments

xhp-150

Journals have retracted three out of the four papers flagged by the Office of Research Integrity during its investigation of a University of Oregon neuroscience student, David Anderson.

Last month, when we first reported on the case, Anderson told us that he “made an error in judgment,” and took “full responsibility.” Two of the retraction notes say that Anderson “knowingly falsified data,” and cited the Office of Research Integrity case summary.

All three papers focus on memory.

The note for the first retraction, from the  Journal of Experimental Psychology: Human Perception and Performance, reveals exactly how Anderson falsified data in the paper. It’s paywalled — tsk, tsk — but printed here in full:

Accounting professor notches 30 (!) retractions after misconduct finding

with 4 comments

James Hunton, via Bentley University

It began with a retraction due to a “misstatement” in November 2012, which led to an investigation that found the first author, James E. Hunton, guilty of misconduct.  Now, the floodgates have opened, and Hunton has 31 retractions under his belt, making him the newest addition to the Retraction Watch leaderboard.

A month after the first retraction in 2012, Hunton resigned from his accounting professorship at Bentley University, citing family and health concerns.

Then, in 2014, a university investigation concluded that Hunton fabricated data in two papers and may have destroyed evidence. The first paper was the one retracted from Accounting Review for a misstatement; the second was retracted from Contemporary Accounting Research in December 2014. Even though the investigation centered around two publications, the university suggested more may be affected:

Rabbit redo: Paper on lepus hepatitis pulled for mutation that “was not supposed to be present”

with one comment

JGVThe authors of recent article about the rabbit hepatitis E virus have pulled the paper after discovering an unexpected mutation in their viral clone that likely affected the analysis.

They realized their mistake soon after the article, “RNA transcripts of full-length cDNA clones of rabbit hepatitis E virus are infectious in rabbits,” was published online in the Journal of General Virology in November, 2014. They withdrew the article before it made it into print.

The article came from a group led by Xiang-Jin Meng, of the Virginia-Maryland College of Veterinary Medicine, an offshoot of Virginia Tech and the University of Maryland.

Here’s the notice, which — tsk tsk — sits behind a pay wall: Read the rest of this entry »

Fungus among us, but what kind? Typing error spawns retraction for mushroom paper

with 4 comments

natprodresAs every mushroom lover knows, weekend mycology is no sport for the lily-livered. Tasty species often look awfully like their deadly cousins. Turns out, typing can even be problematic for the experts.

Natural Products Research is retracting a 2014 paper on shelf fungus because… well, it wasn’t about shelf fungus after all.

The paper, “Chemical constituents: water-soluble vitamins, free amino acids and sugar profile from Ganoderma adspersum,” was written by Ibrahim Kivrak, a food chemist at Mugla Sitki Kocman University in Mugla, Turkey. It analyzed the nutritional components of G. adspersum, and found, per the abstract:

Exosome pioneer’s paper retracted after investigation finds “multiple” faked figures

with 3 comments

JImmunolThe Journal of Immunology is retracting a 2006 article about the role of exosomes in pregnancy at the behest of the University of Louisville in Kentucky, following a misconduct investigation that “determined multiple figures” in the paper were falsified.

First author Douglas Taylor is a pioneer in exosome biology, having discovered the release of exosomes from tumor cells in the 1970s.

The retracted paper identified “significant quantitative and qualitative differences in released exosomes” in the placentas of fetuses delivered prematurely compared to those delivered without complications at term, particularly relating to immune regulation.  It has been cited 150 times, according to Thomson Scientific’s Web of Knowledge.

Here’s the retraction note (which is paywalled – tsk, tsk): Read the rest of this entry »

Scientists “wish to resign as co-authors:” Quantum dot paper retracted

with 21 comments

chemcommChemical Communications has retracted a 2015 article by a group of researchers in China over concerns about fabricated data and an incredible shrinking list of authors.

The paper, “N, S co-doped graphene quantum dots from a single source precursor used for photodynamic cancer therapy under two-photon excitation,” was ostensibly written by nine researchers at the Collaborative Innovation Center for Marine Biomass Fiber, Materials and Textiles of Shandong Province, the Shandong Sino-Japanese Center for Collaborative Research of Carbon Nanomaterials, Laboratory of Fiber Materials and Modern Textiles, the Growing Base for State Key Laboratory at the  College of Chemical Science and Engineering at Qingdao University, and Mayo Clinic, in Rochester, Minn.

Highly cited paper on women and heart disease retracted for failure to replicate

without comments

jcemA highly cited study examining the risks of heart disease in post-menopausal women with symptoms of polycystic ovary syndrome (PCOS) has been retracted by its authors because they could not replicate the results.

Here’s the retraction notice for the paper, which appeared in the Journal of Clinical Endocrinology & Metabolism: Read the rest of this entry »

Two more retractions appear for prominent MIT cancer researcher Robert Weinberg

with 8 comments

genes and developmentTwo identical retraction notices have popped up for MIT professor Robert Weinberg, a highly-cited cancer researcher who had a retraction and a correction in 2013, both in Cancer Cell. 

These two new retractions, in Genes and Development, stem directly from another paper by Weinberg and colleagues in Cell that will apparently be retracted, as the “same analytical methodology was used,” according to the notices [see bottom of the post for an update].

Weinberg is highly regarded, and at least 20 of his papers have been cited over a thousand times.

First author Scott Valastyan was a promising postdoc at the time of the paper’s publication. He was a 2011 Runyon Fellow at Harvard, a three-year, $156,000 award for outstanding cancer postdocs. He doesn’t seem to have published anything since 2012, though he is listed as a joint inventor with Weinberg on patents filed in 2009 and 2014.

Here are the notices for “Concomitant suppression of three target genes can explain the impact of a microRNA on metastasis” (cited 73 times, according to Thomson Scientific’s Web of Knowledge) and “Activation of miR-31 function in already-established metastases elicits metastatic regression” (cited 54 times), both paywalled: Read the rest of this entry »

Warning: plagiarism may be hazardous to your safety paper

with one comment

12 Process Safety and Environmental Protection (once)A paper on making emergency evacuations more efficient at facilities that handle hazardous materials has been retracted for plagiarism.

According to the Process Safety and Environmental Protection retraction notice, the 2013 paper, by a group at Tsinghua University in Beijing, plagiarized part of a 2007 article by Greek researchers called “Modeling emergency evacuation for major hazard industrial sites.” (The 2007 article has been cited 46 times, according to Google Scholar.)

Authors retract 2007 PNAS paper on aging due to figure’s “unintentional anomalies”

with 15 comments

pnas 2515The authors of a 2007 PNAS paper that provided molecular details for how calorie restriction may act on Sir2 enzymes to extend life are now retracting their research after discovering a figure was compromised by “several unintentional anomalies in the background image.”

According to study author David W. Piston at Vanderbilt University, first author Qinghong Zhang cut and pasted images together to beautify a figure showing how a form of sugar affects the expression of SIRT1, the mammalian version of the Sir2 enzyme: Read the rest of this entry »
