Researchers decry study warning of low-carb diet risks

Nutrition and DiabetesAdvocates of low-carbohydrate diet are voicing concern about a recent paper that suggested the diet could cause weight gain, contrary to previous research. One expert has even called for its retraction.

The study, published in Nutrition & Diabetes in February, also found that the low-carb diet did little to prevent the progression of type 2 diabetes. Researchers have since criticized the study for drawing these conclusions based on data from a handful of mice, using a poor proxy for the human version of the diet.

One expert took to social media to warn against the study’s message regarding the low-carb, high-fat diet (LCHF); for instance, obesity & nutrition researcher and author, Zoë Harcombe from Newport, Wales, tweeted: Continue reading Researchers decry study warning of low-carb diet risks

In major shift, medical journal to publish protocols along with clinical trials

AIMA major medical journal has updated its instructions to authors, now requiring that they publish protocols of clinical trials, along with any changes made along the way.

We learned of this change via the COMPare project, which has been tracking trial protocol changes in major medical journals — and been critical of the Annals of Internal Medicine‘s response to those changes. However, Darren Taichman, the executive deputy editor of the journal, told us the journal’s decision to publish trial protocols was a long time coming: Continue reading In major shift, medical journal to publish protocols along with clinical trials

After painful retraction, authors republish replicated findings five years later

chembiochemIt was one of the most difficult posts we’ve ever written: A researcher’s eagerness to publish a paper before asking all co-authors for their permission forced him to retract the article, wasting a postdoc’s time and destroying a professional relationship in the process.

This 2011 post wasn’t difficult to write because the facts were complex; they weren’t particularly (although the science involved was intricate). Rather, the man responsible for the incident, Graham Ellis-Davies, was so clearly and sincerely distressed by the mistake he’d made, it was impossible not to feel sorry for the him.

Well, we’re delighted to report that the tale has a happy ending. Ellis-Davies and his former postdoc have recently republished their once-retracted work with a new set of co-authors — and in the same journal that previous retracted it. What’s more, they have turned what initially was a proof-of-concept study into a much more robust article with exciting implications for the field.  Continue reading After painful retraction, authors republish replicated findings five years later

“I shared:” Can tagging papers that share data boost the practice?

Psychological Science

After a journal began tagging papers that adopted open science practices — such as sharing data and materials — a few other scientists may have been nudged into doing the same.

In January 2014, Psychological Science began rewarding digital badges to authors who committed to open science practices such as sharing the data and materials. A study published today in PLOS Biology looks at whether publicizing such behavior helps encourage others to follow their leads. 

The authors summarize their main findings in the paper:

“Mixed up” images earn biologists four retractions

525480Four different journals have pulled papers from the same authors due to alleged duplication or manipulation of images.

All four papers have two authors in common Jianting Miao and Wei Zhang, both based at The Fourth Military Medical University in Xi’an City, Shaanxi, China. Many of the other co-authors are also listed in two or three of the retracted papers.

Miao claims that the photographs got “mixed up” due to the researchers’ “great carelessness” and “insufficient knowledge.” He told us:

Duke researcher adds another retraction in JCI, bringing count to 15

JCIWe’ve found another retraction for Erin Potts-Kant, a former researcher at Duke, bringing her total to 15.

Yesterday we reported on two new retractions for Potts-Kant in PLoS ONE, which earned her a spot in the top 30 on our leaderboard. As with the others, the latest paper, in the Journal of Clinical Investigation, is marred by “unreliable” data.

Here’s the retraction notice for “In utero supplementation with methyl donors enhances allergic airway disease in mice“:

Biologist under investigation asks journal to swap image, journal retracts the paper

When a researcher discovered one of the images in her papers was a duplication, she asked the journal to fix it — but the journal decided to retract the paper entirely.

The researcher, Suchitra Sumitran-Holgersson, is currently being investigated by the University of Gothenburg in Sweden after a number of her papers were questioned on PubPeer. She told us the duplication was the result of ‘‘genuine human error.’’ Tissue Engineering Part A, however, decided the request to swap the image was a ‘‘cause for concern,’’ and chose to retract the paper. 

Here’s the retraction notice:

New Jersey university biologist earns funding ban for doctoring more than 40 images

John Pastorino

A researcher has agreed to a five-year ban on Federal U.S. funding for research after the Office of Research Integrity (ORI) determined that he had falsified or fabricated more than 40 images in nine papers.

The findings, released by the ORI today, are another chapter in a case involving John Pastorino, a cell biologist at Rowan University. In February, we reported that two journals had issued expressions of concern (EOCs) for six of his papers.

Pastorino, according to the ORI,  Continue reading New Jersey university biologist earns funding ban for doctoring more than 40 images

Duke pulmonary researcher up to 14 retractions, putting her on our leaderboard

PLOS OneA pair of Duke researchers who each have more than 10 retractions have earned some more.

Both of the newly retracted papers — originally published in 2012 by PLOS ONE — list Erin Potts-Kant as a co-author; one includes her former supervisor, Michael Foster, as lead author. The pair has since left Duke (Potts-Kant was arrested for using school credit cards to shop at the likes of Target, and Foster retired). The reason provided for these retractions will be familiar to anyone who’s been following their case — there were “concerns about the reliability” of the data.

By our count, Potts-Kant now has 14 retractions, making her one of the few women to hold a position on our leaderboard.

Here’s the retraction notice for “Iron Supplementation Decreases Severity of Allergic Inflammation in Murine Lung,” a paper that lists both Foster and Potts-Kant as authors:
