Is the bulk of fMRI data questionable?

Last week, a study brought into question years of research conducted using the neuroimaging technique functional magnetic resonance imaging (fMRI). The new paper, published in PNAS, particularly raised eyebrows for suggesting that the rates of false positives in studies using fMRI could be up to 70%, which may affect many of the approximately 40,000 studies in academic literature that have so far used the technique. We spoke to the Anders Eklund, from Linköping University in Sweden, who was the first author of the study. Continue reading Is the bulk of fMRI data questionable?

Unwitting co-author requests retraction of melatonin paper

Screen Shot 2016-06-08 at 10.54.58 PMNine years ago, a well-known pharmacologist hosted a researcher from another university in his lab. On a Saturday night last September, he learned while surfing Google Scholar that they had published a paper together.

Marco Cosentino, who works at the University of Insubria in Italy, know that Seema Rai, a zoologist at Guru Ghasidas Vishwavidyalaya in India, had collected data during during her six months in his lab, but had warned her they were too preliminary to publish. She published the data — on melatonin’s role in immunity — anyway, last summer in the Journal of Clinical & Cellular Immunology, listing Cosentino as the second author.

The day after he discovered the paper, Cosentino sent an email to the editor in chief of the journal, Charles Malemud, explaining why he did not approve of the publication:

Authors pull Nature paper about DEET and flies

Nature CoverAuthors have retracted a Nature paper which identified neurons that render flies sensitive to a potent insect repellent, after losing confidence in the findings. The first author, however, said she does not agree with the retraction, noting that she continues to believe the data are correct.

According to the notice, the remaining authors say they no longer support the claim that certain neurons in the antennae of fruit flies are repelled by DEET, the active ingredient in many insect repellents. The last author told us some of the paper’s results are not in doubt; nevertheless, he added, the paper would not have been published in Nature without the key conclusion, so he and most of his co-authors have pulled the paper in its entirety.

Alongside the retraction, the journal has also published a Brief Communications Arising article by scientists who were unable to reproduce the paper’s findings.

Here’s the retraction notice, published today:

Fake email for corresponding author forces neuro journal to retract paper

Cellular and Molecular Neurobiologychair of a neurobiology department in China has requested the retraction of a paper on which he was unwittingly listed as the lead and corresponding author.

How could a corresponding author — you know, the person with whom the journal corresponds about the paper — be added without their consent? It seems that a fraudulent email account was involved in this case. The address listed for Cheng He, a researcher at the Second Military Medical University in Shanghai, didn’t belong to him, said a spokesperson for Springer.

According to the retraction notice for “Identification of the Interaction Between the Human Homologue of the Arabidopsis COP9 Signalosome Subunit 7a and Olig1:”

JAMA: No plan to retract article on fetal pain, despite outcry from anti-abortion activists

JAMAJAMA has announced it does not intend to retract a 2005 review article about fetal pain, despite requests from anti-abortion activists who claim it has been misused in debates about the procedure.

Earlier this month, JAMA told one anti-abortion critic that it would take a look at the paper, which suggested that fetuses can’t feel pain before the third trimester. Critics have argued that newer findings have shown pain sensation appears earlier in gestation, yet the 2005 data continue to be cited in the discussion around abortion. What’s more, critics have lamented that some of the authors failed to mention their ties to the abortion industry.

But in a letter sent yesterday to James Agresti, Howard Bauchner, Editor in Chief at JAMA and The JAMA Network, writes: Continue reading JAMA: No plan to retract article on fetal pain, despite outcry from anti-abortion activists

Pro-lifers call for JAMA to retract 2005 paper about fetal pain

JAMAPro-life activists have asked JAMA to retract a 2005 paper that suggested fetuses can’t feel pain before the third trimester.

Critics are arguing that newer findings have shown pain sensation appears earlier in gestation, yet the 2005 data continue to be cited in the discussion around abortion. What’s more, they note, some of the authors failed to mention their ties to the abortion industry.

The 2005 paper has been cited 191 times, according to Thomson Reuters Web of Science. We spoke with Howard Bauchner, Editor in Chief at JAMA and The JAMA Network, who told us something similar to what he said last week, when PETA asked to retract a paper they claim could be harmful to elephants: Continue reading Pro-lifers call for JAMA to retract 2005 paper about fetal pain

Epilepsy researcher gets retraction, correction after former colleague flags work

EpilipsiaEpilepsy researcher Toni Schneider has received a retraction and a correction in quick succession, after a former colleague raised red flags about the work. 

The retraction for Schneider, based at the University of Köln in Germany, is for “unintentional inclusion of erroneous data” due to limitations of the recording system used in the paper, according to the notice. 

Marco Weiergräber, a former colleague of Schneider’s, has claimed that the authors of the paper did not use the test properly. The journal editor, however, told us he believes the original analysis is an “honest mistake,” and there is “no evidence” to suggest that the authors intentionally published incorrect analyses.

Here’s the retraction notice, issued by the journal in March 2016: Continue reading Epilepsy researcher gets retraction, correction after former colleague flags work

Neuro journal pulls article for data theft, prompts misconduct probe

annneuro

Neuroscientists have retracted a research letter less than two months after it appeared, admitting they appeared to pass off others’ data as their own.

Two of the researchers are listed as affiliated with the University of California, San Francisco (UCSF), and the incident has led to a misconduct investigation at the institution, a UCSF spokesperson told us.

The article, “DNAJC6 variants in Parkinson’s disease and amyotrophic lateral sclerosis,” appeared in April. It was quickly followed by this notice, dated in May: Continue reading Neuro journal pulls article for data theft, prompts misconduct probe

PLOS ONE paper plagiarized from 17 articles — yes, 17

PLOSOneA PLOS ONE paper about chronic pain plagiarized from multiple sources — 17, in fact.

According to the retraction notice released by the journal last week, the paper contains “extensive verbatim use of text from other sources.”

How did this make it past the editors? The journal published the paper in 2012 — before it began screening papers for plagiarism, according to a spokesperson.

Here’s the retraction notice for “The Effect of Social Stress on Chronic Pain Perception in Female and Male Mice:”

The scientists, from whom the data originated, contacted the journal.

The editor in chief of the journal investigated the case, the spokesperson told us, and then issued this retraction notice:
