Investigation prompts 5th retraction for cancer researcher for “unresolvable concerns”

3.coverAn investigation at the University of New South Wales in Australia has led to a fifth retraction for a cancer researcher long accused of misconduct, due to “unresolvable concerns” with some images.

As we reported in December, UNSW cleared Levon Khachigian of misconduct, concluding that his previous issues stemmed from “genuine error or honest oversight.” Now, Circulation Research is retracting one of his papers after an investigation commissioned by UNSW was unable to find electronic records for two similar images from a 2009 paper, nor records of the images in original lab books.

Again, the retraction note affirms that this is not a sign of misconduct:

UNSW has not attributed any instance of research misconduct or responsibility for the unavailability of the original data to Professor Khachigian or to any of the authors of the publication.

After hesitating, Science retracts chemistry paper against authors’ wishes

F1.mediumToday, Science has retracted a 2004 paper that’s been under scrutiny for years, despite the authors’ objections.

This paper has a long backstory: Recently, a report from the National Science Foundation’s Office of Inspector General surfaced that announced the agency had cut off the authors from funding. Last month, editor Marcia McNutt told us that the journal planned to retract the paper as soon as possible. Then, on January 21st, “just as we were going to press with the retraction,” said McNutt, the authors submitted a correction, which Science wanted to take some time to consider.

Now, the paper has a retraction note, against the wishes of authors Bruce Eaton and Dan Feldheim, currently at the University of Colorado.

Here it is the retraction note:

An engineer has retracted three papers on a method for making nanoscale materials that are useful in solar cells.

The papers, all published in ACS Applied Materials & Interfaces, contain irregularities in data, and one includes images “which have been published elsewhere and identified with different samples,” according to the note.

The first author on all three papers is Khalid Mahmood, who — according to the bio from a talk he gave last year on efficient solar cells — is currently a postdoc at King Abdullah University of Science and Technology in Saudi Arabia. He did the work in the retracted papers while a student at the Korea Advanced Institute of Science and Technology, where, according to the bio, he completed his PhD in two years.

Here’s the retraction note for the first paper (which also contains a typo in the title — “electrospay”)

If you notice an obvious problem with a paper in your field, it should be relatively easy to alert the journal’s readers to the issue, right? Unfortunately, for a group of nutrition researchers led by David B. Allison at the University of Alabama at Birmingham, that is not their experience. Allison and his co-author Andrew Brown talked to us about a commentary they’ve published in today’s Nature, which describes the barriers they encountered to correcting the record. 

Retraction Watch: You were focusing on your field (nutrition), and after finding dozens of “substantial or invalidating errors,” you had to stop writing letters to the authors or journals, simply because you didn’t have time to keep up with it all. Do you expect the same amount of significant errors are present in papers from other fields? Continue reading Want to correct the scientific literature? Good luck

Makeup use linked to testosterone levels? Not so fast, says retraction

Psych SciA psychology journal is retracting a 2015 paper that attracted press coverage by suggesting women’s hormone levels drive their desire to be attractive, after a colleague alerted the last author to flaws in the statistical analysis.

The paper, published online in November, found women prefer to wear makeup when there is more testosterone present in their saliva. The findings were picked up by various media including Psychology Today (“Feeling hormonal? Slap on the makeup”), and even made it onto reddit.com.

However, upon discovering a problem in the analysis of the data, the authors realized that central finding didn’t hold up, according to Psychological Science‘s interim editor, Stephen Lindsay: Continue reading Makeup use linked to testosterone levels? Not so fast, says retraction

Letter calls for retraction of yoga weight loss paper

IntJYoga_2016_9_1A paper concluding that a specific series of yoga poses is effective at promoting weight loss in obese women has a call for retraction in a letter to the editor of the International Journal of Yoga. 

The study followed 87 women for 8 weeks as they completed a regular routine of  yoga, circuit training, or walking on a treadmill. “Suryanamaskar: An equivalent approach towards management of physical fitness in obese females” concludes that

All three methods were effective in weight and physical fitness management.

But a group of heath researchers at the University of Alabama at Birmingham led by David Allison failed to replicate the statistical tests on some of the data. In a recent letter to the editor, “Unsubstantiated conclusions from improper statistical design and analysis of a randomized controlled trial,” they express skepticism about the paper’s claims, and ask the journal to retract it:

“Innocent mistake” leads to bioethics article retraction

jbiA July article that incorrectly called out nine leading bioethics journals for their lack of availability to researchers in low- and middle-income countries is being pulled after editors of the indicted journals refuted the allegations.

The last author on the article, published in the Journal of Bioethical Inquiry, told us an “innocent mistake” and difficulty navigating a website led the authors to incorrectly note that nine journals had not made their contents available through the World Health Organization’s Health InterNetwork Research Initiative database (HINARI), which gives bioethicists who live in low- and middle-income countries access to research articles either free of charge or at reduced cost. The authors argued that the mistake didn’t affect the paper’s conclusions, but the journal disagreed, and opted to pull the paper entirely.

After searching through the database, first author Subrata Chattopadhyay mistakenly determined that the journals had not made their contents available through HINARI, when in fact they were listed but on a different part of the website.

Even with the error, the authors maintain that their conclusions remain sound and that the field is shaped by a “hegemony of Western bioethics.” Continue reading “Innocent mistake” leads to bioethics article retraction

Sharing data is a good thing. But we need to consider the costs.

Liz Wager

Last week, the International Committee of Medical Journal Editors proposed requiring authors to share deidentified patient data underlying the published results of clinical trials within six months of publication. The proposal has earned much support but also some concerns – for example that other scientists might poach the findings, acting as the New England Journal of Medicine dubbed “research parasites.” Elizabeth Wager, a member of the board of directors of our parent organization, disagrees with that concern, but raises another issue – namely, the unintended consequences of data sharing on other, more effective initiatives to make reporting more transparent.

The recent proposal from the ICMJE may appear, at first glance, a positive step towards better clinical trial reporting. However, I’m concerned that this new requirement might undermine other more effective initiatives to increase the efficiency of research, such as the publication of protocols and full study reports. Here’s why.

All actions have costs, risks, and benefits: Making partial data sharing a condition of publication is no exception. The costs are hard to quantify but undoubtedly not trivial.  Putting clinical data into a usable format and making it meaningful to other researchers requires considerable time and effort by knowledgeable people. To this must be added the costs of establishing and maintaining suitable repositories and of checking compliance.

I’m not saying that open data does not have any benefits. Continue reading Sharing data is a good thing. But we need to consider the costs.

Wound healing paper injured beyond repair

Errors in the interpretation of some of the data — the result of “procedural flaws” —  are to blame for the retraction of a paper on a way to help skin grow back after injury.

The paper explores a method involving nanofibers. According to the abstract:

In this study, tilapia skin collagen sponge and electrospun nanofibers were developed for wound dressing…the collagen nanofibers stimulated the skin regeneration rapidly and effectively in vivo.

The paper was published January 19, 2015 by ACS Applied Materials and Interfaces, then retracted eight months later, in August. It has not been cited, according to Thomson Scientific’s Web of Knowledge.

Here’s the retraction note:

Science publishes Voinnet’s 19th, 20th, and 21st corrections

351-6271-coverProminent plant biologist Olivier Voinnet has issued three more corrections in this week’s issue of Science.

Collectively, the papers have earned more than 1400 citations, according to Thomson Scientific’s Web of Knowledge.

By our count, he’s now at 21 corrections and seven retractions, following months of questions about his work. He’s been the subject of an investigation that found he “breached his duty of care,” and another which found evidence of scientific misconduct.

One correction goes against the recommendation of the ETH Commission to retract the paper for “well documented intentional manipulations.” According to the correction note, the incorrect figures did not “alter the data in any material way that could be construed to benefit the results and their conclusions.” That correction is the only one of the three for which Voinnet takes full responsibility.

The other two corrections place the responsibility on  Continue reading Science publishes Voinnet’s 19th, 20th, and 21st corrections
