Nature Communications retracts much-criticized paper on mentorship

A month after announcing it would be conducting a “priority” investigation into a November 17 paper that claimed women in science fare better with male rather than female mentors, Nature Communications has retracted the article.

In the article, “The association between early career informal mentorship in academic collaborations and junior author performance,” the authors — a trio from New York University’s campus in Abu Dhabi — write that “While current diversity policies encourage same-gender mentorships to retain women in academia, our findings raise the possibility that opposite-gender mentorship may actually increase the impact of women who pursue a scientific career.” It drew nearly immediate criticism, for example:

On November 19, the journal added an editor’s note saying it would be looking into these criticisms, and today, the article was retracted following review by three experts. The retraction notice reads, in part:

Nature Communications looking into paper on mentorship after strong negative reaction

A Nature journal has announced that it is conducting a “priority” investigation into a new paper claiming that women in science fare better with male rather than female mentors. 

The article, “The association between early career informal mentorship in academic collaborations and junior author performance,” appeared in Nature Communications on November 17, and was written by a trio of authors from New York University’s campus in Abu Dhabi. 

According to the abstract:

Why journal editors should dig deeper when authors ask for a retraction

Imagine you’re a journal editor. A group of authors sends you a request to retract one of their papers, saying that “during figure assembly certain images were inappropriately processed.”

What do you do next? Do you ask some tough questions about just what “inappropriately processed” means? Do you check your files for whether the author’s institution had told you about an investigation into the work? Do you Google the author’s names? Do you…search Retraction Watch?

It seems unlikely that any of those things happened in the case of a recent retraction from Nature Communications, or, if they did, they don’t seem to have informed the notice. We don’t know for sure, because, as is typical, the journal isn’t saying much. But here’s what we do know. Continue reading Why journal editors should dig deeper when authors ask for a retraction

“Devastating:” Authors retract paper in Nature journal upon discovering error

Several years ago, Chris Dames thought he had made an exciting discovery, a “secret sauce” that would allow him to design a device using a novel mechanism.

In a 2014 Nature Communications paper, Dames—who works at the University of California at Berkeley—and his team described the first experimental results for the device, a photon thermal diode. A thermal diode conducts heat in one direction but not in the other, and in theory, could have broad applications—for example, provide barriers that shield buildings from excess heat or use heat to power computers.

But two years later, in August 2016, a colleague thought he had discovered a fundamental error in the design of the experiments. Bair Budaev, who also works at the University of California at Berkeley, believed that the authors made a “a fundamental symmetry error” which invalidated their results.

Dear journals: Clean up your act. Regards, Concerned Biostatistician

Romain-Daniel Gosselin

Recently, a biostatistician sent an open letter to editors of 10 major science journals, urging them to pay more attention to common statistical problems with papers. Specifically, Romain-Daniel Gosselin, Founder and CEO of Biotelligences, which trains researchers in biostatistics, counted how many of 10 recent papers in each of the 10 journals contained two common problems: omitting the sample size used in experiments, as well as the tests used as part of the statistical analyses. (Short answer: Too many.) Below, we have reproduced his letter.

Dear Editors and Colleagues,

I write this letter as a biologist and instructor of biostatistics, concerned about the disregard for statistical reporting that is threatening scientific reproducibility. I hereby urge you to spearhead the strict application of existing guidelines on statistical reporting. Continue reading Dear journals: Clean up your act. Regards, Concerned Biostatistician

Two more retractions for stem cell researcher appealing her dismissal

Susana Gonzalez

Susana Gonzalez, a rising star in stem cell research, has had a rough year.

In addition to being fired from her former research institute (which she is now appealing), one of her grants (totaling nearly 2 million Euros) was suspended. Most recently, she has received two new retractions in Nature Communications over figure duplications and missing raw data. By our count, she has a total of three retractions.

Both of the new notices say the papers contained figures duplicated in other papers by Gonzalez, and neither includes Gonzalez among the list of co-authors who agreed to the retraction.

Gonzalez was dismissed from her position at the National Center for Cardiovascular Research (CNIC) in Spain last February over allegations of misconduct. According to the head of basic research at CNIC, Gonzalez is still embroiled in a legal battle with the Center over her dismissal. Vicente Andrés could not go into detail because of the ongoing litigation, but he told us: Continue reading Two more retractions for stem cell researcher appealing her dismissal

Karolinska requests retraction of 2014 Macchiarini paper

Paolo Macchiarini

It has been a tough couple of years for surgeon Paolo Macchiarini, once lauded for pioneering a groundbreaking procedure to transplant tracheas.

After a series of documentaries prompted his former employer, Karolinska Institutet (KI), to reopen a misconduct investigation against him, KI has today released one verdict regarding a 2014 Nature Communications paper: guilty.

KI said it is contacting the journal to request a retraction of the paper, which has already been flagged with an expression of concern.

Here’s more from a release from the institution: Continue reading Karolinska requests retraction of 2014 Macchiarini paper

Macchiarini paper in Nature journal earns expression of concern for data questions

nature-communications-228x300Nature Communications has issued an expression of concern for a 2014 paper by beleaguered surgeon Paolo Macchiarini, citing concerns over whether the paper accurately reports the experiments that were carried out.

According to the notice, Macchiarini, a former rising star in the field of transplant medicine, agrees with the expression of concern. Three of his 22 co-authors have objected.

“Experimental orthotopic transplantation of a tissue-engineered oesophagus in rats” describes transplanting an esophagus into rats that was seeded with their own stem cells, and notes that all animals survived the study period (14 days), and gained more weight than rats given a placebo operation. It’s a topic Macchiarini has made famous, as the first surgeon to perform a similar procedure with a human tracheal transplant. But he’s faced charges of misconduct in the last few years, resulting in his dismissal from Karolinska Institutet (KI).

Here’s the text of the notice, scheduled to go live at 10 a.m. UK time today: Continue reading Macchiarini paper in Nature journal earns expression of concern for data questions

Author appeals retraction after co-authors dispute Nature Comm paper

nature comm

Two weeks after Nature Communications published a paper on asymmetric cell division in July, it posted a retraction notice saying the paper was submitted “without the knowledge or consent” of all but the corresponding author.

The following day the journal “amended” the retraction note to include the initials of the corresponding author, Aicha Metchat, then based at European Molecular Biology Laboratory in Heidelberg, Germany.

The final notice for “An actin-dependent spindle position checkpoint ensures the asymmetric division in mouse oocytes” reads:

Lack of citation prompts correction in Nature journal

nature communicationsIt’s not unusual to hear authors bemoan the fact that a new paper doesn’t cite their work that set the stage for a scientific advance. “The journal limited me to [a seemingly abitrary number of] references,” authors sometimes shrug, with or without apology. This week, however, we found a case of that which seems to have been resolved to everyone’s satisfaction.

The authors of a September 2013 article in Nature Communications have issued a correction for the piece, which failed to cite the source of a key step in their experiment.

The article, “Val66Met polymorphism of BDNF alters prodomain structure to induce neuronal growth cone retraction,” came from the lab of William “Clay” Bracken, a biochemist at Weill Cornell Medical College. According to the abstract: Continue reading Lack of citation prompts correction in Nature journal
