Science has retracted a high-profile immunology paper after a probe concluded the corresponding author had committed misconduct.
The paper — which initially caught media attention for suggesting a protein could help boost the immune system’s ability to fight off tumors — has been under a cloud of suspicion since last year, when the journal tagged it with an expression of concern, citing a university investigation.
That investigation — at Imperial College London — has concluded that the paper contained problematic figures that were the result of research misconduct. All were prepared by last and corresponding author Philip Ashton-Rickardt, who took full responsibility. Even though the paper was published in 2015, some original blots and accompanying details have disappeared.
The move comes after a group of researchers alleged the paper contains missing data, and the authors followed a problematic methodology. In September, however, the co-authors’ institution, Uppsala University in Sweden, concluded there wasn’t enough evidence to launch a misconduct investigation.
A high-profile plant scientist who has been racking up corrections and retractions at a steady clip has had another paper — this one from Science — retracted.
The retraction, of a paper that had been previously corrected, is the eighth for Olivier Voinnet. According to the notice, the correction did not address all the figure problems with the paper, which “cannot be considered the result of mistakes.”
An expert group at Uppsala University has recommended not proceeding with a full investigation into allegations of misconduct in a high-profile Science paper showing how human pollution may be harming fish.
The June paper — which caught the media’s attention for suggesting fish larvae are eating small particles of plastic rather than their natural prey — became the focus of scrutiny soon after it was published when a group of researchers raised allegations of misconduct. Earlier this year, Science told us it was considering issuing an Expression of Concern (EOC) for the paper, and Uppsala said it was conducting an inquiry, the first step in determining whether to launch a formal investigation.
The expert group who conducted the preliminary investigation has ultimately recommended against an investigation of the paper, according to an Uppsala spokesperson: Read the rest of this entry »
Science 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 »
The former director of the National Institute of General Medical Sciences at the U.S. National Institutes of Health has a new job. On July 1st, biochemist Jeremy Berg will take the helm as the editor-in-chief of Science. He’s currently the associate senior vice chancellor for science strategy and planning in the health sciences at the University of Pittsburgh. We spoke to him about challenges he’ll be facing in his new role: treating science’s replication problem, boosting transparency, and making papers as widely available as possible.
You told us in an earlier conversation that diagnosing and treating science’s replication problem is major issue in publishing. Can you give us some specifics about how you plan to address it at Science? Read the rest of this entry »
Science has a new editor-in-chief.
As of July 1st, Jeremy M. Berg will be at the helm of the family of journals published by the American Association for the Advancement of Science, replacing Marcia McNutt. McNutt is leaving to become president of the National Academy of Sciences.
Berg, now associate senior vice chancellor for science strategy and planning in the health sciences at the University of Pittsburgh, has led the National Institute of General Medical Sciences at the U.S. National Institutes of Health (NIH), and was president of the American Society for Biochemistry and Molecular Biology (ASBMB) from 2012-2014.
Berg who said in an AAAS press release that he is “thrilled and humbled by the opportunity to work with the team at Science and AAAS,” assumes the role following a year in which one of the world’s most prominent academic journals has faced significant scrutiny. Read the rest of this entry »
How easy is it to change people’s minds? In 2014, a Science study suggested that a short conversation could have a lasting impact on people’s opinions about gay marriage – but left readers disappointed when it was retracted only months later, after the first author admitted to falsifying some of the details of the study, including data collection. We found out about the problems with the paper thanks to Joshua Kalla at the University of California, Berkeley and David Broockman at Stanford University, who tried to repeat the remarkable findings. Last week, Kalla and Broockman published a Science paper suggesting what the 2014 paper showed was, in fact, correct – they found that 10-minute conversations about the struggles facing transgender people reduced prejudices against them for months afterwards. We spoke with Kalla and Broockman about the remarkable results from their paper, and the shadow of the earlier retraction.
Retraction Watch: Let’s start with your latest paper. You found that when hundreds of people had a short (average of 10 minutes) face-to-face conversation with a canvasser (some of whom were transgender), they showed more acceptance of transgender people three months later than people with the same level of “transphobia” who’d talked to the canvasser about recycling. Were you surprised by this result, given that a similar finding from Michael LaCour and Donald Green, with same-sex marriage, had been retracted last year? Read the rest of this entry »
Approximately six out of 10 economics studies published in the field’s most reputable journals — American Economic Review and the Quarterly Journal of Economics — are replicable, according to a study published today in Science.
The authors repeated the results of 18 papers published between 2011 and 2014 and found 11 — approximately 61% — lived up to their claims. But the study found the replicated effect to be on average only 66% of that reported in the earlier studies, which suggests that authors of the original papers may have exaggerated the trends they reported.
Colin Camerer, a behavioral economist at the California Institute of Technology in Pasadena, who co-authored the study, “Evaluating replicability of laboratory experiments in economics,” told us: Read the rest of this entry »
Stefan Franzen doesn’t give up. Ten years ago, he began to suspect the data behind his colleagues’ research about using RNA to make palladium nanoparticles, a potentially valuable tool that ended up as a Science paper. Recently, the National Science Foundation (NSF) decided to cut off funding for Bruce Eaton and Dan Feldheim — currently at the University of Colorado at Boulder — and last week, Science retracted the paper. We talked to Franzen, based at North Carolina State University (NCSU), about his decade-long efforts, and how it feels to be finally vindicated.
Retraction Watch: How did you first begin to suspect the findings by Eaton and Feldheim?
Stefan Franzen: Starting in early 2005, I was collaborating with Drs. Eaton and Feldheim at NCSU, thanks to two joint grants from the W.M. Keck Foundation and NSF. During a group meeting in December of 2005, a graduate student showed electron microscopy data that were inconsistent with the assignment of the particles as palladium. Over time, we kept producing more data that called their findings into question; in April 2006, a postdoc showed that the hexagonal particles could be obtained without RNA. By then, I could see that there was a significant discrepancy between what was written in the articles and what was done and observed in the laboratory.
