Following revelations of data issues and other problems (which crashed our server last week), Science is retracting a paper claiming that short conversations could change people’s minds on same-sex marriage.
The co-author who admitted to faking the data “does not agree” to the retraction, according to Science. Here’s more from the note: Continue reading Science retracts troubled gay canvassing study against LaCour’s objections
Note: This story has been updated to include the journal’s response. See below.
Yesterday, John Bohannon described in i09.com how he successfully”created” health news — he conducted a flawed trial of the health benefits of chocolate, gamed the data to produce statistically significant results, and published the findings in the International Archives of Medicine:
It was terrible science. The results are meaningless, and the health claims that the media blasted out to millions of people around the world are utterly unfounded.
Given that the author himself says the study is meaningless, clearly, the journal will retract it, yes? Continue reading Should the chocolate-diet sting study be retracted? And why the coverage doesn’t surprise a news watchdog
The Karolinska Institutet in Sweden has released an English translation of an external review that found Paolo Macchiarini, a celebrated surgeon who is credited with creating tracheas from cadavers and patients’ own stem cells, committed misconduct in a series of papers describing the work.
You can read the entire report, news of which was first reported by Science, here. The investigator, Bengt Gerdin, of Uppsala University, considered a series of allegations about Macchiarini’s papers, and found a number of them lived up to the verdict of misconduct. There were seven affected papers, not six, as was reported last week based on the initial findings (reported in Swedish).
For instance, in a 2014 Nature Communications paper describing the procedure in rats, Gerdin found that the scientists erred when none of the listed authors could assume responsibility for a CT image showing rats with “a smooth and patent oesophagus” (the researcher who took it asked to be left off the author list when he disagreed with how it was being interpreted), among other issues: Continue reading Misconduct found in 7 papers by Macchiarini, says English write-up of investigation
Chemical Communications has retracted a 2015 article by a group of researchers in China over concerns about fabricated data and an incredible shrinking list of authors.
The paper, “N, S co-doped graphene quantum dots from a single source precursor used for photodynamic cancer therapy under two-photon excitation,” was ostensibly written by nine researchers at the Collaborative Innovation Center for Marine Biomass Fiber, Materials and Textiles of Shandong Province, the Shandong Sino-Japanese Center for Collaborative Research of Carbon Nanomaterials, Laboratory of Fiber Materials and Modern Textiles, the Growing Base for State Key Laboratory at the College of Chemical Science and Engineering at Qingdao University, and Mayo Clinic, in Rochester, Minn.
According to the abstract: Continue reading Scientists “wish to resign as co-authors:” Quantum dot paper retracted
Citing an “abuse of the scientific publishing system,” the editors of Geomorphology have retracted a paper from a quartet of geologists in China for containing “significant similarity” to four other papers.
It is the second recent retraction for the group: In a loop of self-plagiarism, the Geomorphology paper was cited as a source of copied material in a retraction last month from Sedimentary Geology.
This most recent retraction is of a January 2014 paper, “The influence of sand bed temperature on lift-off and falling parameters in windblown sand flux,” analyzing the rise and fall of windblown sand based on the temperature of the sand bed.
Here is the full text of the notice:

An article published earlier this year has been retracted from the Journal of Heat Transfer. But the retraction notice gives no information about what was amiss.
The article is entitled “Neural Network Methodology for Modeling Heat Transfer in Wake Flow,” and the retraction notice, in full, reads: Continue reading Fluid mechanics article retracted with no explanation
Archives of Trauma Research has retracted a 2014 paper on bullying by a group in Iran who appear to have been double-fisted in their approach to publishing.
The article, “Epidemiological Pattern of Bullying Among School Children in Mazandaran Province, Iran,” was written by researchers from Shahid Beheshti University of Medical Sciences, in Tehran. Its conclusions:
Different forms of bullying have a distinct nature and the epidemiological pattern indicates that bullying exists in the Iranian schools. Thus, the effective bullying prevention and appropriate intervention programs are recommended.
Here’s the notice:

Authors of a study on cardiac repair after heart attack are retracting it from Basic Research in Cardiology because they used “the same samples… to represent two distinct groups on two occasions.”
We find the language of the retraction somewhat confusing, but to the best of our understanding it means that they compared apples to the exact same apples.
The study, published online in 2012, examined the mechanism behind the beneficial effects of a procedure called postconditioning in treating heart attacks. Here’s the retraction notice: Continue reading Heart repair study retraction marks second for Mercer University researcher
As we noted Saturday, there was so much happening around the web last week that it made sense to break up Weekend Reads, especially since this is a holiday weekend in the U.S. and elsewhere. Here’s part 2: Continue reading Weekend reads, part 2: Oldest-ever PhD; most embarrassing citation ever; blame the antibodies?
This week at Retraction Watch was dominated by the Science same-sex marriage study, after we broke the news Wednesday morning that one of its authors had requested its retraction. (And crashed our servers in the process.) So the first section of this Weekend Reads will focus on pieces following up on that story:
But there was plenty more happening this week: Continue reading Weekend reads: Gay canvassing study redux; editors fired; how the world’s biggest faker was caught
