Sample tampering leads to plant scientist’s 7th retraction

Jorge Vivanco

Plant scientist Jorge Vivanco has earned his seventh retraction, after an investigation found data from soil samples were “intentionally fabricated by a third party.”

Vivanco and his former postdoc Harsh Bais made a name for themselves by discovering the secret behind a nasty invasive plant: It secretes a harmful form of catechin, which kills everything around it, suggesting it could serve as a new herbicide. The findings earned the researchers a story in the New York Times.

In the newly retracted paper, published in 2005, first author Laura Perry — then a postdoc at Colorado State University — further explored the role of the plant-killer, working with Vivanco as the last author. However, when a team working in the building next door had trouble finding catechin in their samples, Perry took another look, and concluded that her samples had been tampered with.

In other words, Perry told us:   Continue reading Sample tampering leads to plant scientist’s 7th retraction

Molecular self-assembly paper fell apart

1049_soft_matter_f2c-900Authors are retracting a 2014 paper about how liquid-crystalline materials self-organize in low temperature conditions after realizing they had measured the temperatures incorrectly.

The error affected three figures and a table in “Milestone in the NTB phase investigation and beyond: direct insight into molecular self-assembly.” The paper, published in Soft Matter, has been cited three times, according to Thomson Reuters Web of Science.

The retraction note, published in August, offers more detail as to exactly what went wrong:

Death camp dog satire retracted when German journal wasn’t in on joke

Screen Shot 2016-03-01 at 2.46.54 PMTotalitarianism and Democracy has removed a paper claiming that German Shepherds belonging to guards at the Berlin Wall descended from dogs used at concentration camps, after learning that the paper was a work of satire, The Guardian reports.

The paper, and its author, are the creation of the anonymous group “Christiane Schulte and friends.”

This isn’t the first hoax we’ve seen in publishing: Don’t forget journalist John Bohannon, who submitted hundreds of fake papers to open access journals, and more recently conjured up a study that showed chocolate helps you lose weight. (And, of course, a paper in a Romanian magazine that listed porn star Ron Jeremy and Michael Jackson among its references.) Like many other hoaxers, the group say in a statement their purpose was to shine light on problems in academic publishing.

The latest victim: a Dresden-based journal, The Guardian explains:

Entire paper about cell division plagiarized

Chinese med jA paper about the role of specific proteins in the separation of newly replicated chromosomes is being retracted from the Chinese Medical Journal, after editors found out that the entire article was plagiarized.

The study, “MreBCD Associated Cytoskeleton is Required for Proper Segregation of the Chromosomal Terminus during the Division Cycle of Escherichia Coli,” names Feng Lu as the corresponding author and claims that the work was done in his lab at the Medical School of Henan University in Henan, China. The misappropriation came to light when a member of Lawrence Rothfield’s lab at the University of Connecticut saw the paper after it was published online last April, and realized that it was an exact replica of an unpublished paper that Rothfield’s own lab had produced.

Here’s the retraction note from the journal: Continue reading Entire paper about cell division plagiarized

Surgery studies lacked ethics committee approval

3Surgery Today has pulled a pair of papers that share many authors because the studies they describe were not approved by an institutional ethics committee.

One describes a case in which the researchers removed a mass from a 64-year-old woman’s small intestine; the other describes how the authors removed a growth from a patient’s pancreas. They conclude that the surgery techniques used — like a laparoscopic pancreaticoduodenectomy, a take on the “Whipple Procedure” — can be “feasible, safe, and effective” in certain patients.

The papers share several authors, including a first author, Akihiro Cho, whose affiliation on the papers is Chiba Cancer Center Hospital in Japan. They also share a retraction note, which explains how the journal learned of the issue:

Upon discovering several errors, authors retract gastric cancer paper

mmr_12_4After finding several errors in their paper about the molecular activity underlying gastric cancer, the authors unanimously decided to retract it.

According to the retraction note, three figures in the paper had β‑actin bands that were omitted, interchanged, or both.

The retraction note provides the details:

Journals flag 6 papers, request investigation of New Jersey university biologists

Two journals have published six expressions of concern for a pair of biologists at Rowan University, and are asking the university to undertake an investigation.

We contacted the editors of the two journals — Journal of Cell Science and Biology Open — who both said they decided to flag the papers after a reader raised concerns about potential re-use of blot images. The six papers are co-authored by John G. Pastorino, a molecular biologist at Rowan University in New Jersey and Nataly Shulga, whose LinkedIn identifies her as a research specialist at the same institution. According to the nearly identical notes, the journals (which share a publisher) undertook a review of the original data, but “felt unable to resolve this matter.”

The expressions of concern — five from the  Journal of Cell Science and one from Biology Open — include pretty much the same text. Here’s the note that appeared in JCS:

STAP stem cell researcher Obokata loses another paper

Nature protocols

The first author of two high-profile Nature retractions about a technique to easily create stem cells has lost another paper in Nature Protocols.

Haruko Obokata, once “a lab director’s dream,” according to The New Yorker, also had her PhD revoked from Waseda University last fall.

After learning of concerns that two figures are “very similar” and “some of the error bars look unevenly positioned,” the rest of the authors were unable to locate the raw data, according to the note. The journal could not reach Obokata for comment before publishing the retraction.

“Reproducible subcutaneous transplantation of cell sheets into recipient mice” has been cited 21 times, according to Thomson Reuters Web of Science. It was published in June 2011, soon after Obokata earned her PhD. 

Here’s the note:

Cyberterrorism paper under attack for plagiarizing from multiple sources

2012032903645393A paper about combating cyberterrorism is coming under fire after allegations of plagiarism sparked on social media.

Soon after the paper was published by the journal Computer Technology and Application in 2015, Orgnet LLC, a network analysis software company, announced on Twitter that the paper took content from its webpage. The firm tweeted: Continue reading Cyberterrorism paper under attack for plagiarizing from multiple sources

Methodology of paper linking vaccine to behavioral issues “seriously flawed,” says retraction

S0264410X

After temporarily removing a paper that suggested a link between the vaccine for the human papillomavirus (HPV) and behavioral issues, the journal has now retracted it.

Vaccine says the reason is “serious concerns regarding the scientific soundness of the article,” including flawed methodology and unjustified claims.

Christopher A. Shaw, a co-author on the paper and a researcher at the University of British Columbia, told us he has seen the notice, but doesn’t know the specific issues the journal had with the paper:

We still don’t know why [Editor in Chief] Dr Poland removed the article.

Here’s the retraction notice for “Behavioral abnormalities in young female mice following administration of aluminum adjuvants and the human papillomavirus (HPV) vaccine Gardasil:”
