The authors of a highly cited 2016 research letter on a way to improve the efficiency of solar panels have retracted their work following “concerns about the reproducibility.”
Given the potential importance of the data, it would be nice to know what exactly went wrong, and why. However, the retraction notice doesn’t provide many details, and doesn’t even specify if the authors did indeed fail to reproduce the data.
The letter, titled “Graded bandgap perovskite solar cells,” was published in Nature Materials by a group out of the University of California at Berkeley and the affiliated Lawrence Berkeley National Laboratory. The 2016 article has been cited 16 times, according to Clarivate Analytics’ Web of Science, earning it the ranking of “highly cited.”
Berkeley heralded the findings in a press release as a “major advance” in the field of solar energy:

Last month, Nature Ecology & Evolution published a series of responses to a previous article recommending essential reading for all ecologists. In one response, the authors argue that the list is highly biased in favor of white male authors, and raises the problem of bullying and harassment in academia. But the letter is missing one key reference from its original submission: To a recent news story in Science reporting “disturbing” sexual harassment allegations against a prominent field researcher.
Why is the reference missing?
Because the editor at Nature Ecology & Evolution asked the authors to take it out, citing concerns about libel.
Here’s the note the authors received on their original submission:

A Nobel Laureate has retracted a 2016 paper in Nature Chemistry that explored the origins of life on earth, after discovering the main conclusions were not correct.
Some researchers who study the origins of life on Earth have hypothesized that RNA evolved before DNA or proteins. If true, RNA would have needed a way to replicate without enzymes. The Nature Chemistry paper found that a certain type of peptide — which may have existed in our early history — made it possible for RNA to copy itself.
Jack W. Szostak—a professor of chemistry and chemical biology at Harvard University in Cambridge, Mass., who shared the 2009 Nobel Prize in Physiology or Medicine with Elizabeth Blackburn and Carol Greider for their pioneering research on aging—told us he was “incredibly excited” when he “thought we had at least a partial solution to this problem,” which researchers have been working on for over 50 years.
But in subsequent experiments, Tivoli Olsen — a member of Szostak’s lab — could not reproduce the 2016 findings. When she reviewed the experiments from the Nature Chemistry paper, she found that the team had misinterpreted the initial data: The peptide in question did not appear to provide an environment that fostered RNA replication.
The errors were “definitely embarrassing,” Szostak told us: Continue reading ”Definitely embarrassing:” Nobel Laureate retracts non-reproducible paper in Nature journal
Following heavy criticism of its decision to correct — instead of retract — a paper accused of plagiarism, Scientific Reports is adding an editor’s note to the paper and forming a committee to review the case.
The 2016 paper in question has been accused of plagiarism by a researcher at Johns Hopkins, Michael Beer. Following the initial allegation, the journal decided to correct, not retract, the paper. After we covered the story, nearly two dozen Hopkins researchers threatened to resign if the journal didn’t retract the paper. This week, the journal reaffirmed its initial decision, and the resignations are pouring in.
Yesterday, Suzanne Farley, Executive Editor of Scientific Reports, a Nature Publishing Group journal, sent us a statement:

More than a dozen members of the editorial board at Scientific Reports have resigned after the journal decided not to retract a 2016 paper that a researcher claims plagiarized his work.
As of this morning, 19 people — mostly researchers based at Johns Hopkins — had stepped down from the board, according to Hopkins researcher Steven Salzberg. Salzberg organized the response after learning of the issue from colleague Michael Beer, who has accused the 2016 paper of plagiarism.
Monday morning, Richard White, the editor of the journal (published by Springer Nature), sent an email to Salzberg and the researchers who had threatened to resign if the paper wasn’t retracted, saying:

As a journal editor, are you tired of hearing the same excuses from authors who are facing allegations of problematic data? If so, you’re not alone.
Recently, an editor of the journal Oncogene co-authored an editorial in the journal listing the types of excuses he often hears — and why none of them is valid. Writing the article with editor Justin Stebbing of Imperial College/Imperial Healthcare NHS Trust is David Sanders of Purdue University. Sanders himself has raised allegations of misconduct against a cancer researcher (and is currently being sued for defamation as a result).
Here are the problematic excuses they encounter:

More than 20 faculty members at Johns Hopkins University have signed a letter to Scientific Reports saying they will resign from the editorial board if the journal doesn’t retract a 2016 paper.
The paper is problematic, they argue, because a biologist at Johns Hopkins claims it plagiarized his work. One of that biologist’s colleagues at Hopkins has already resigned from the journal’s editorial board over its decision to correct (and not retract) the paper; last week, another 21 people told the journal they’d do the same.
The letter to the journal also includes a side-by-side comparison between the 2016 paper and the work it allegedly plagiarized. The board members note:

Is having money linked to bad behavior?
A high profile paper published in 2012 in the Proceedings of the National Academy of Sciences (PNAS) set out to answer that question — and found that yes, the more money people have, the more likely they are to lie, cheat, and steal. And the greedier they are, the worse they behave. But when a more recent paper tried to replicate some of those findings, it couldn’t.
It turns out, both the original paper and the paper that tried to replicate it contained errors. Although neither appear to affect the main conclusions, the authors of the 2016 replication recently issued a correction; the error in the 2012 paper was initially deemed too insignificant to correct, but the journal has decided to revisit the idea of issuing a correction.
A representative of PNAS told us that the replication paper — and reporting by Retraction Watch — is the reason why: Continue reading Are rich people meaner? While trying to find out, two teams find errors in each other’s work
A biologist is crying foul at a journal’s decision to correct (and not retract) a paper he claims plagiarized his work — and one of his colleagues has resigned from the journal’s editorial board as a result.
The 2016 paper, published by Scientific Reports, is an application of a previously published algorithm designed to better identify regulatory sequences in DNA. The three authors, based at the Shenzhen campus of the Harbin Institute of Technology, used the technique to identify recombination spots in DNA. They called it SVM-gkm.
On April 2, Michael Beer of Johns Hopkins University in Baltimore notified the editors of Scientific Reports that he believed the paper had plagiarized his work. Despite Beer’s efforts, the journal ultimately decided to issue a correction notice, which cites “errors” and the authors’ failure to credit Beer’s work. That isn’t good enough for Beer — nor one of his colleagues at Johns Hopkins, who resigned from the journal’s editorial board saying “the recent affair with Mike Beer’s work being plagiarized did not impress me.”

Nature has added an “editor’s note” to a high-profile August paper alerting readers to the fact that the article has been subject to criticism.
Journals often flag papers that are being debated — what’s unusual here is that the journal doesn’t label the notice as an official “Expression of Concern,” which are indexed by PubMed. Yet the Nature notice reads just like an expression of concern.
Here’s the text of the new notice, which was added October 2 (and spotted by Paul Knoepfler):
