Author of controversial Science fish-microplastics paper committed “intentional” misconduct, says Uppsala

with 5 comments

An investigation at Uppsala University has found the authors of a retracted Science paper — which explored the threat of human pollution on fish — guilty of misconduct.  

The decision, published yesterday, states that both authorsPeter Eklöv and Oona Lönnstedt“violated the regulations on ethical approval for animal experimentation,” and Lönnstedt, the paper’s corresponding author, “fabricated the results.”

Eklöv told us: Read the rest of this entry »

Caught Our Notice: Forgot to make your article open access? It’ll cost you (with a correction)

Title: Industrial antifoam agents impair ethanol fermentation and induce stress responses in yeast cells

What Caught Our Attention: When authors decide they want to make their articles freely available after they’ve already been published, how should publishers indicate the change, if at all? Recently, Ross Mounce (@rmounce) thought it was odd a Springer journal issued a formal correction notice when the authors wanted to make their paper freely available, and we can’t say we disagree.  As he posted on Twitter:

Caught Our Notice: To know if someone’s been vaccinated, just asking isn’t enough

Title: Hepatitis B Virus Infection in Preconception Period Among Women of Reproductive Age in Rural China – A Nationwide Study

What Caught Our Attention: When researchers set out to study hepatitis B among women in rural China, and they wanted to know if the women had been vaccinated against the virus, they simply asked them. While that can sometimes be useful, apparently it was a mistake in this case, as the reliance on patient memory injected too much doubt into these findings.  Read the rest of this entry »

Caught Our Notice: Author of controversial retracted paper earns Swedish gov’t grant

with 2 comments

Last week, a Swedish government funding agency announced 325 recipients of grants in Natural and Engineering Sciences. We don’t normally write about grant announcements, but we’re flagging this one because one recipient may be familiar to our readers.

It is Peter Eklöv of Uppsala University, a co-author of a now-retracted Science paper about the potential dangers of microplastics to fish.

Eklov will receive 800,000 ($94,784 USD) each year in 2018-2020 and 900,000 ($106,632 USD) in 2021, totalling 3,300,000 ($355,440 USD). The granting agency is the Swedish Research Council, controlled by Sweden’s Ministry of Education and Research.

Eklöv‘s retracted paper — which he co-authored with Oona Lönnstedt — got significant media coverage when it first appeared in June 2016, as it suggested fish larvae prefer to eat microplastic over their own natural prey. But soon after it was published, a group of researchers raised several allegations, including that the paper contained missing data and used a problematic methodology Read the rest of this entry »

Swedish review board finds misconduct by Macchiarini, calls for six retractions

with 2 comments

Paolo Macchiarini

An ethical review board in Sweden is asking journals to retract six papers co-authored by former star surgeon Paolo Macchiarini, after concluding that he and his co-authors committed misconduct.

One of the papers is the seminal 2011 article in The Lancet, which described the first case of a transplant using an artificial trachea seeded with the patient’s own stem cells, and now bears an expression of concern from The Lancet editors. Over time, multiple authors have asked to be removed from the paper.

The Expert Group on Scientific Misconduct at the Central Ethical Review Board has determined that concerns over that paper — and five others co-authored by Macchiarini, once based at the Karolinska Institutet (KI) — were justified. In a press release, it says:

Swedish prosecutor won’t pursue criminal case against Macchiarini

without comments

Paolo Macchiarini

A Swedish prosecutor has announced she won’t continue investigating a former star surgeon who has since fallen from grace.

Paolo Macchiarini made a name for himself by transplanting synthetic tracheas. After multiple patients died, however, allegations against the researcher have continued to swirl. He was dismissed from the Karolinska Institutet last year, after it reopened its misconduct investigation. The Swedish prosecutor was investigating Macchiarini’s role in the deaths of three out of four patients he operated on five times between 2011-2013.

Although the prosecution concluded that most of the operations proceeded “negligently,” it could not conclude Macchiarini was criminally responsible.

According to the public prosecutor Jennie Nordin:

“No wrongdoing had occurred,” says Karolinska, following investigation of cancer research

without comments

A journal has removed an expression of concern for a 2011 paper after Karolinska Institutet (KI) “concluded no wrongdoing had occurred.” 

In June, Journal of Cell Science (JCS) issued the expression of concern, after a reader contacted the editors with questions about the data in one of the figures. JCS investigated but could not resolve the issue, and in March 2017 turned the case over to KI where the authors are based.

The 2011 paper had already received a correction in 2016, citing inadvertent figure duplication.

In late August, KI concluded its investigation into the 2011 paper by last author Boris Zhivotovsky; JCS has now updated the expression of concern with a publisher’s note: Read the rest of this entry »

“We do not want to create false hope”: Authors retract Cell paper they can’t replicate

with 24 comments

A few years ago, researchers in Sweden had something to celebrate: They thought they had discovered a chink in the armor of the most common type of malignant brain cancer.

In a 2014 Cell paper, the team — led by Patrik Ernfors at the Karolinska Institutet — reported that they had identified a small molecule that could target and kill glioblastoma cells — the cancer that U.S. Senator John McCain was just diagnosed with — and prolong survival in mice with the disease. 

Satish Srinivas Kitambi, the paper’s first author, who is also based at the Karolinska Institutet, said the results got the team “really excited:” Read the rest of this entry »

Journal flags cancer paper from Karolinska researchers

without comments

A journal has issued an expression of concern (EOC) for a 2011 cancer paper, while Karolinska Institutet investigates “concerns” about some of the data.

After the Journal of Cell Science (JCS) received a tip from a reader, it investigated, but was unable to resolve the concerns. So the journal asked KI–where all the authors work–to investigate further, and issued an EOC to alert readers that there may be an issue with the paper.

According to the notice, the questions center on data from Fig. 1A, but the notice does not specify the nature of the concerns. The 2011 paper received a correction in 2016, which cites inadvertent figure duplication.

Earlier this year, the paper’s last author Boris Zhivotovsky and second author Helin Vakifahmetoglu-Norberg retracted a 2008 paper from Oncogene over potential image duplication. That retraction caught our attention because it was prompted by a 2016 correction to the paper, which had raised additional questions about potential duplication; ultimately, the authors retracted both the paper and its correction.

Here’s the expression of concern for the 2011 JCS paper: Read the rest of this entry »

Updated: Science fish-microplastics paper retracted

without comments

Despite continuing to vigorously defend their work, the authors of a controversial paper about the effects of human pollution asked Science to retract the paper last week.

According to a release from Uppsala University issued today, authors Peter Eklöv and Oona Lönnstedt submitted their request to Science last week, noting they wanted to withdraw the paper “as long as a suspicion of misconduct remains.”

The release — which echoes a statement that was also provided to Nature — notes:
