Retraction notice for GMO paper updated to include fraud

with 8 comments

fns2015012717103119Earlier this year, a nutrition journal retracted an article about the potential dangers of eating food containing genetically modified organisms (GMOs), noting the paper contained a duplicated image.

At the time, news outlets in Italy were reporting accusations that the last author, Federico Infascelli, an animal nutrition researcher at the University of Naples, had falsified some of his research.

Food and Nutrition Sciences has now updated its initial notice, saying the paper was pulled for data fabrication. In addition, Infascelli is no longer listed on its editorial board – he is included on an archived link to the editorial board from March 2016, but not on the current list of members.

Here is the updated version of the retraction notice for “Gamma-Glutamyl Transferase Activity in Kids Born from Goats Fed Genetically Modified Soybean:” Read the rest of this entry »

Ecology journal flags carnivore paper under investigation

without comments

journal-of-applied-ecologyAn ecology journal has issued an expression of concern (EOC) for a recently published study, citing an institutional investigation about the data and conclusions.

According to the notice — issued by the Journal of Applied Ecology — the author’s institution in South Africa has received a report from an independent examiner. The editors are reviewing the paper — about reducing the impact of lethal carnivores such as black-backed jackals — “in light of this information.”

An official from the journal told us the investigation has to do with “relevant background information” that was not included in the study, published online in December.

Here’s the EOC, published earlier this month: Read the rest of this entry »

Renewable energy researcher with troubled record loses another paper

with 2 comments

renewable-sustainable-energy-reviewsA renewable energy researcher who recycled material in several papers — and has already agreed to withdraw 10 studies — has lost another paper.

In January, we reported that six of 10 papers flagged by an investigation into author Shyi-Min Lu have either been retracted or withdrawn. Now, Lu has lost another paper that was not among the previous ten — again, for reproducing figures from earlier works without seeking permission from original authors. This paper was on a hot topic: gas hydrates, considered to be a potential new energy source to replace oil in the 21st century.

The investigations into Lu’s work took place at the Industrial Technology Research Institute in Hsinchu, Taiwan, where he was formerly based, and the National Taiwan University, in Taipei, Taiwan, which fired Lu from his position at the university’s energy research center.

Here’s the retraction notice in Renewable and Sustainable Energy Reviews, issued last month: Read the rest of this entry »

You’ve been dupe’d: Results so nice, they’re published twice

without comments

obesity surgeryWith retraction notices continuing to pour in, we like to occasionally take the opportunity to cover several at a time to keep up.

We’ve compiled a handful of retractions that were all issued to papers that were published twice by at least one of the same authors — known as duplication. (Sometimes, this can be the publisher’s fault, although that doesn’t appear to be the case in any of the following examples.)

So here are five recently retracted papers that were pulled because of duplication: Read the rest of this entry »

High-profile Science paper on fish and plastics may earn notice of concern

with 3 comments

science mag coverScience is considering adding an expression of concern (EOC) to a June paper that caught the media’s attention for showing how human pollution may be harming fish, following allegations of research misconduct.

A group of researchers allege the paper — which suggested fish larvae are eating small particles of plastic rather than their natural prey — contains missing data and used a problematic methodology. After the researchers submitted a formal letter (available here), Uppsala University in Sweden is now conducting an inquiry, the first step in determining whether to launch a formal investigation.

A spokesperson from Science told Retraction Watch that once the journal independently verifies that an investigation is underway, it will issue an EOC for the paper: Read the rest of this entry »

Authors retract study that found pollution near fracking sites

with 10 comments

Environmental Science and TechnologyThe authors of two environmental papers, including one about the effects of fracking on human health, have retracted them after discovering crucial mistakes.

One of the studies reported an increased level of air pollution near gas extraction sites, and the other suggested that 2010’s Deepwater Horizon oil spill in the Gulf of Mexico contributed to air contamination.

According to the corresponding author of both papers, Kim Anderson at Oregon State University, the journal plans to publish new versions of both papers in the next few days. In the case of the fracking paper, the conclusions have been reversed — the original paper stated pollution levels exceeded limits set by the U.S. Environmental Protection Agency (EPA) for lifetime cancer risk, but the corrected data set the risks below EPA levels.

The fracking paper received some media attention when it was released, as it tapped into long-standing concerns about the environmental dangers of hydraulic fracturing (fracking), which extracts natural gas from the earth. A press release that accompanied the paper quoted Anderson as warning: Read the rest of this entry »

More than $100M worth of research may be tainted by govt lab misconduct

with 4 comments

usgsMisconduct by a chemist at a Colorado lab run by the U.S. Geological Survey (USGS) has potentially affected  24 research and assessment projects, supported by $108 million in federal funding, government officials have disclosed.

According to a June 15 statement from the Office of the Inspector General of the U.S. Department of the Interior, which oversees the USGS, the operator of a mass spectrometer in the Inorganic Section of the Energy Resources Program’s (ERP) Energy Geochemistry Laboratory in Lakewood has been accused of scientific misconduct and manipulating data. The unit is responsible for conducting coal and water quality assessments in projects both in the United States and abroad.

The inorganic section closed following the discovery of the misconduct, and we have yet to learn the fate of the employee involved. As the statement notes, problems with the lab’s data were common knowledge among workers at the facility: Read the rest of this entry »

Ecologists pull paper on how climate change affects moths after model mixup

with 4 comments

science advancesEcologists have retracted a paper published only months ago in Science Advances, after realizing that they had misinterpreted a climate model.

The October paper examined the effects of climate change on populations of 155 species of British moths and butterflies. According to a press release from the authors’ institution, the University of York:

Using data collected by thousands of volunteers through ‘citizen science’ schemes, responses to recent climate change were seen to vary greatly from species to species.

But the authors quickly realized that the variation they had measured was not due to climate change alone, according to the retraction notice they issued for the paper last week:

Biologist critiques own paper, journal retracts it — against her wishes

with 10 comments

Evolution Cover ImageThe journal Evolution has retracted a 2007 paper about the roles of the different sexes in searching for mates, after the same author critiqued the work in a later paper. 

The case raises important questions about when retractions are appropriate, and whether they can have a chilling effect on scientific discourse. Although Hanna Kokko of the University of Zurich, Switzerland — who co-authored both papers — agreed that the academic literature needed to be corrected, she didn’t want to retract the earlier paper; the journal imposed that course of action, said Kokko

Let’s take a look at the retraction note: Read the rest of this entry »

Journal retracts groundwater pollution paper for plagiarism

with one comment

ecotoxThe journal Ecotoxicology has retracted a paper that described a way to analyze nitrates in groundwater after discovering the authors had lifted a substantial amount of material from three other papers.

Here is the retraction notice for “Isotopic analysis of N and O in NO3 – by selective bacterial reduction to N2O for groundwater pollution:” Read the rest of this entry »
