In 2009, Donald Williamson made what many biologists said was an extraordinary claim: The reason caterpillars become butterflies is that two different species accidentally mated with one another. As Brendan Borrell explained at the time in Scientific American: Continue reading A flying what? Symbiosis retracts paper claiming new species arise from accidental mating
Science expresses “concern” about Stapel paper
A day after Tilburg University released its preliminary report on psychologist Diederik Stapel, Science has issued an “expression of concern” about one of his papers.
The 2011 article, titled “Coping with Chaos: How Disordered Contexts Promote Stereotyping and Discrimination,” was written by Stapel and Siegwart Lindenberg, a Tilburg colleague with an appointment at the University of Groningen.
Here’s the notice, signed by Science editor Bruce Alberts: Continue reading Science expresses “concern” about Stapel paper
Stapel report finds faked data in at least 30 papers, possibly more
Our comment threads lit up today with news that the interim report on the misconduct investigation into Diederik Stapel has arrived — and what it says ain’t pretty. Continue reading Stapel report finds faked data in at least 30 papers, possibly more
How do Croatian scientists deal with retractions and misconduct? A guest post by Mico Tatalovic
Today, we have the pleasure of presenting a guest post from Mico Tatalovic, who has just published a piece in the monthly magazine Tehnopolis on retractions in journals in his home country, Croatia. Here, he describes the reporting that went into that feature, which he says was inspired by Retraction Watch.
You may think that in a country with regular plagiarism scandals there would be many retractions. But a search for ‘retractions’ in the open-access depository of academic journals, Hrcak Srce, shows only two retraction notices among more than 70,000 articles in 271 journals indexed there.
There may be several reasons for this. Continue reading How do Croatian scientists deal with retractions and misconduct? A guest post by Mico Tatalovic

A retraction as a group’s papers on smoking and weight loss are too close for comfort
The American Journal of Physiology Endocrinology and Metabolism is retracting a 2009 article by Japanese researchers who appeared to be so fond of their data they published them thrice.
The paper, “Dual suppression of adipogenesis by cigarette smoke through activation of the aryl hydrocarbon receptor and induction of endoplasmic reticulum stress,” by Masanori Kitamura and colleagues, looked at the biochemical mechanism by which cigarette smokers seem to be able to keep weight off. It has been cited eight times, according to Thomson Scientific’s Web of Knowledge.
But according to the retraction notice: Continue reading A retraction as a group’s papers on smoking and weight loss are too close for comfort
Cancer journal retracts herbal medicine paper, citing misconduct probe
The journal Cancer Prevention Research has retracted a 2009 article by a group of scientists from the University of Kentucky after the institution determined that one of the figures in the article wasn’t kosher.
The article, “Psoralidin, an Herbal Molecule, Inhibits Phosphatidylinositol 3-Kinase–Mediated Akt Signaling in Androgen-Independent Prostate Cancer Cells,” has been cited 9 times, according to Thomson Scientific’s Web of Knowledge. Earlier iterations of the research were presented at two cancer meetings in 2008.

Retracted retraction leaves Genomics paper intact — but authors wonder if anyone will know
Last March, the journal Genomics retracted a paper, “Discovery of transcriptional regulators and signaling pathways in the developing pituitary gland by bioinformatic and genomic approaches,” for reasons that don’t really fit into a tight lede sentence. Let’s just say that at times the problems involved both questions of authorship and the validity of the research. More on all that in a moment.
Meanwhile, things change. Now the journal, an Elsevier title, is un-retracting (that can’t be a real word, can it?) the retraction. You’d think that would please the authors, and it does to an extent. But they also wonder, legitimately, whether the original retraction will refuse to relinquish its grip on the resurrected article and consign it to database oblivion.
First, some background. Continue reading Retracted retraction leaves Genomics paper intact — but authors wonder if anyone will know
Report on pot and crime goes up in smoke as RAND retracts it

Maybe they just hallucinated it.
The RAND Corporation has retracted a study linking Los Angeles pot dispensaries to drops in crime, the Los Angeles Times reports. The problem: RAND hadn’t included data from the Los Angeles Police Department (LAPD). The institute tells the Times, referring to RAND researchers:
“They made mistakes,” said Debra Knopman, a Rand vice president and director of the infrastructure, safety and environment division. “What we’re wrestling with is how the mistakes went undetected.”
The report was peer-reviewed, RAND said, and retractions are uncommon: Continue reading Report on pot and crime goes up in smoke as RAND retracts it
National University of Singapore official who co-authored Melendez papers won’t be part of investigation

The Alirio Melendez case is likely to become quite complicated, as the National University of Singapore (NUS) looks into about 70 papers by the researcher whose work has already been the subject of a retraction and Expression of Concern. One such wrinkle seemed to have already surfaced when a blog called the Gigamole Diaries pointed out last week that an NUS dean apparently connected to the investigation had co-authored two papers with Melendez:
…the authorship list for Melendez papers reads almost like a Who’s Who in the medical school, and includes heads of departments, Vice Deans and prominent individuals in the office of the NUS Vice President. Interestingly Prof Barry Halliwell, who is NUS Deputy President (Research and Technology), and who has been cited as fronting the investigation into the Melendez publications is himself associated with at least 2 Melendez publications.
We checked with Halliwell, who has indeed spoken to numerous media outlets about the investigation. He tells us: Continue reading National University of Singapore official who co-authored Melendez papers won’t be part of investigation
