That new beetle? Actually, it’s really an old beetle

A team of entomologists in India had to put their new species celebration on hold last year, when they found out their discovery had already been discovered.

The Journal of Insect Science paper, initially published in December 2012, was retracted in October 2013, after several entomologists confirmed that the beetle was actually a previously identified species called Acanthophorus serraticornis. (The notice has a November 2014 date, but we understand that’s because the journal switched servers.)

Here’s the notice for “A new record of longicorn beetle, Acanthophorus rugiceps, from India as a root borer on physic nut, Jatropha curcas, with a description of life stages, biology, and seasonal dynamics”: Continue reading That new beetle? Actually, it’s really an old beetle

Stem cell researcher Hanna “working…to correct the unfortunate and inadvertent mistakes” in papers

Jacob Hanna

Jacob Hanna of Israel’s Weizmann Institute has been a media darling for years, including as a member of the 2010 Technology Review 30 under 35 for his work with stem cells.

However, questions have been mounting about his research, both on PubPeer (which has critical comments for 15 papers he’s an author on) and in other stem cell labs, who have not been able to reproduce much of Hanna’s work.

We asked Hanna about a PubPeer entry specific to a 2005 paper in Blood. Commenters have accused the authors of figure manipulation and possible data republication. Here’s a figure from that post: Continue reading Stem cell researcher Hanna “working…to correct the unfortunate and inadvertent mistakes” in papers

Shingles-stroke connection paper earns expression of concern for “errors in data presentation”

neurologyThe journal Neurology has issued an expression of concern for a paper linking shingles and stroke, which got press attention when it was published.

The journal’s note refers to “errors of data presentation,” which author Judith Breuer more narrowly defined as mistakes during transcription of a table. It’s unclear whether the results themselves – that herpes zoster, the virus that causes shingles, is a risk factor for stroke and other vascular problems – are being called into question.

Here’s the expression of concern for “Herpes zoster as a risk factor for stroke and TIA: A retrospective cohort study in the UK”: Continue reading Shingles-stroke connection paper earns expression of concern for “errors in data presentation”

“You don’t retract a paper, you retract the results within:” Why one scientist still displays one of his mistakes

And now, one from the archives.

In 1989, then MIT grad student Lance Fortnow (he’s now chair of the computer science department at Georgia Tech) wrote a mathematical proof and published it as conference proceedings. He later went to publish the proof in a journal.

But he then discovered “unexpected technical challenges” and published a retraction in 1997. Both are still available on his personal website.

Not everyone would be that transparent. We reached out to ask why he left them up for people to see. He gave us his rationale: Continue reading “You don’t retract a paper, you retract the results within:” Why one scientist still displays one of his mistakes

Revealed: Complaint lodged against Macchiarini, “super-surgeon” under investigation

Retraction Watch has obtained copies of a misconduct complaint filed against surgeon Paolo Macchiarini, who is currently under investigation by the Karolinksa Institute in Stockholm for allegedly downplaying dangers of an experimental surgery, along with other misconduct accusations. We’re posting them here to allow researchers and clinicians to review and perhaps comment on them.

The complaint was from four surgeons at Karolinska Hospital, and was filed in August, as The New York Times reported last month. You can read the full complaint here. An excerpt: Continue reading Revealed: Complaint lodged against Macchiarini, “super-surgeon” under investigation

Dentistry student loses travel grant for duplicating his own work

iadrThe International Association for Dental Research has retracted a student travel award after discovering that the recipient had previously published the work he used to secure the grant, including in an abstract he presented at the same conference last year.

The self-plagiarism was uncovered by an anonymous group of students at the Hong Kong University dentistry school, where the student is a PhD student. The unnamed students sent both the IADR and HKU faculty members a color-coded chart showing identical phrases between the 2014 abstract, a 2013 paper published in the Journal of Periodontal Research called “Human umbilical vein endothelial cells synergize osteo/odontogenic differentiation of periodontal ligament stem cells in 3D cell sheets,” and another abstract the authors presented at the 2013 IADR conference.

The paper and both abstracts were written by P.K.C.P. Panduwawala, who lost the travel grant, along with HKU’s former dean of dentistry L.P. Samaranayake; HKU’s associate dean for research L.J. Jin; and C.F. Zhang, part of HKU’s tissue engineering group.

The IADR’s page now lists the winners with a note at the bottom: Continue reading Dentistry student loses travel grant for duplicating his own work

Paper on controversial stem cell “stamina therapy” retracted

A Korean stem cell journal has retracted a paper on a controversial Italian treatment that involves harvesting stem cells from bone marrow and injecting them back into the patient.

“Stamina therapy” has been pitched as a treatment for everything from Parkinson’s disease to coma, based on a U.S. patent application filed in 2010. The Italian government pledged about $3.9 million in 2013 to support a clinical trial for stamina therapy. More than 100 people signed up for the trials, with a wide range of neurological ailments; half were children.

However, allegations of fraud led to a criminal investigation into the Stamina Foundation’s leader, psychologist David Vannoni, as well as 17 other members of the organization. Continue reading Paper on controversial stem cell “stamina therapy” retracted

Is Rolling Stone retracting its story on UVA sexual assault?

Rolling-Stone-LOGO-2Rolling Stone has published an editor’s note that calls into question their November 19 story, “A Rape on Campus,” which details a UVA student’s alleged gang rape at a fraternity party and her subsequent struggle to get justice from the school.

Shortly after publication, the magazine was criticized for not seeking a statement from the alleged perpetrators, despite the fact that they were not named in the story, and for relying almost entirely on the testimony from one individual.

Here is managing editor Will Dana’s editor’s note: Continue reading Is Rolling Stone retracting its story on UVA sexual assault?
