Paper on chemtrails, a favorite subject of conspiracy theorists, retracted

ijerph-logo

A paper claiming to expose the “tightly held secret” that long clouds trailing from jets are toxic coal fly ash — and not, as the U.S. government says, primarily composed of harmless ice crystals — has been retracted.

The paper is called “Evidence of Coal-Fly-Ash Toxic Chemical Geoengineering in the Troposphere: Consequences for Public Health,” and was published in the International Journal of Environmental Research and Public Health in August. Author J. Marvin Herndon — a geophysicist, and self-described “independent researcher” — also distributed a press release about the findings.

The abstract explains:

The author presents evidence that toxic coal combustion fly ash is the most likely aerosolized particulate sprayed by tanker-jets for geoengineering, weather-modification and climate-modification purposes and describes some of the multifold consequences on public health.

The detailed retraction note, authored by the academic editor of the paper, Paul B. Tchounwou, a biologist at Jackson State University, points out some errors with the science, and notes that the “language of the paper is often not sufficiently scientifically objective:” Continue reading Paper on chemtrails, a favorite subject of conspiracy theorists, retracted

Three retractions for geriatric medicine researcher

Screen Shot 2015-08-20 at 11.51.11 AMA trio of papers on health issues in elderly patients, all sharing an author, have been retracted from Geriatrics & Gerontology International. 

The reasons for the retractions range from expired kits, an “unattributed overlap” with another paper, “authorship issues,” and issues over sample sizes.

Tomader Taha Abdel Rahman, a researcher at Ain Shams University in Cairo, is the first author on two of the papers, and second author on the third.

Here’s the retraction note for a paper that showed elderly adults with chronic hepatitis C are at risk of having cognitive issues:

Stem cell researcher Jacob Hanna’s correction count updated to 10

Thanks to some eagle-eyed readers, we’ve been alerted to some corrections for high profile stem cell scientist Jacob Hanna that we had missed, bringing our count to one retraction and 13 errata on 10 papers.

The problems in the work range from duplications of images, to inadvertent deletions in figures, to failures by his co-authors to disclose funding sources or conflicts of interest. Hanna is the first or last author on 4 of the papers, and one of several on the rest.

First up, a correction to a Cell paper on which Hanna is the first author:

Retraction of grizzly bear-diabetes study follows departure of Amgen scientist for data manipulation

cov150h
The retracted paper made the cover of the August 2014 issue of the journal.

A study that looked to hibernating bears to understand the mechanisms behind diabetes has been retracted because an author based at the biotech company Amgen “manipulated specific experimental data” in two figures.

According to the The Wall Street JournalAmgen discovered the manipulation while reviewing the data following publication of the paper,”Grizzly bears exhibit augmented insulin sensitivity while obese prior to a reversible insulin resistance during hibernation.” Published in Cell Metabolism last year, the paper has been cited 8 times, according to Thomson Scientific’s Web of Knowledge.

A press release from the journal last year — coverage in Science and Nature followed — explained the purpose of the study:

Authors’ pharma ties cause Cochrane to withdraw two diabetes reviews

Cochrane_LogoThe Cochrane Library has withdrawn two reviews evaluating the effectiveness of diabetes treatments because some of the papers’ authors work with pharmaceutical companies.

Bianca Hemmingsen, first author on both reviews, told us the Cochrane Library asked the authors to remove the researchers with ties to pharma, but after one “refused to withdraw,” both papers were pulled entirely.

However, Hemmingsen insists that their employment had no impact on either paper.

This breaks the typical mold for Cochrane withdrawals, which are usually only pulled to indicate updates and show that older reviews no longer represent the best evidence.

Two groups mistakenly publish case reports on the same patient

Journal of Clinical Pharmacy and Therapeutics

Talk about a popular patient: A woman who developed a case of internal bleeding while taking the anticoagulant Xarelto (rivaroxaban) was written up in not one — but two — case reports. The trouble was, both groups didn’t realize what the other was doing, so the more recent article is now being retracted from the Journal of Clinical Pharmacy and Therapeutics.

The authors, a trio of doctors at Sakarya University in Turkey, described the case of a 75 year-old woman who came to the emergency room for fatigue and stomach pain after taking rivaroxaban for three days. A scan revealed a rectus sheath hematoma.

However, the case had already been published a few months earlier in the Indian Journal of Pharmacology by a separate group of doctors from Sakarya, along with authors from Yenikent State Hospital and Vakfikebir State Hospital.

Updated: Author resigns from West Point following paper legitimizing attacks on scholars who question terror tactics

nilj_680x312

[Note: This post has been updated with new information about the author’s resignation.]

Following criticisms of a 2015 paper which proposed attacks on scholars who question the government’s handling of the war on terror, the author has resigned from his post at the U.S. Military Academy at West Point, New York.

The nearly 200-page paper, “Trahison des Professeurs: The Critical Law of Armed Conflict Academy as an Islamist Fifth Column,” appeared in the National Security Law Journal of George Mason University School of Law, in Virginia. It was written by William C. Bradford, who is a somewhat controversial figure.

In the paper, Bradford, assistant professor at the United States Military Academy, criticizes U.S. academics who specialize in armed conflict and claim “that the Islamist jihad is a response to valid grievances against U.S. foreign policy”: Continue reading Updated: Author resigns from West Point following paper legitimizing attacks on scholars who question terror tactics

“Our manuscript unintentionally failed to meet academic and publication standards”

homeHeaderTitleImage_en_US

Authors of a 2014 review paper about the use of “as needed” medications by people with mental health diagnoses are retracting it, but we’re scratching our heads as to why.

The retraction appears in “The experiences of mental health professionals’ and patients’ use of pro re nata (PRN) medication in acute adult mental health care settings: a systematic review protocol of qualitative evidence,” published by The JBI Database of Systematic Reviews and Implementation Reports.

From the abstract of the paper:

Pro re nata is a Latin phrase meaning “for an unforseen need or contingency”…The authors of the systematic review found that although the practice of using “as required” medication is common there is no good evidence of whether this is the best way of helping people to be less agitated when compared to being given a regular dose of medication.

We’re not entirely sure what went wrong here. This is the full contents of the note:

Three retractions for Oregon neuroscience student investigated by ORI

xhp-150

Journals have retracted three out of the four papers flagged by the Office of Research Integrity during its investigation of a University of Oregon neuroscience student, David Anderson.

Last month, when we first reported on the case, Anderson told us that he “made an error in judgment,” and took “full responsibility.” Two of the retraction notes say that Anderson “knowingly falsified data,” and cited the Office of Research Integrity case summary.

All three papers focus on memory.

The note for the first retraction, from the  Journal of Experimental Psychology: Human Perception and Performance, reveals exactly how Anderson falsified data in the paper. It’s paywalled — tsk, tsk — but printed here in full:

A mess: PLOS mistakenly publishes rejected ADHD-herbicide paper, retracts it

logoPLOS One has retracted a paper that links the most commonly used herbicide to ADHD, after it was “published in error.”

According to the note, the paper was “editorially rejected following peer review and consultation with the Editorial Board,” but ended up going through the production process anyway.

When we contacted the authors, they filled us in with more details.
