The reasons for the retractions range from expired kits, an “unattributed overlap” with another paper, “authorship issues,” and issues over sample sizes.
Tomader Taha Abdel Rahman, a researcher at Ain Shams University in Cairo, is the first author on two of the papers, and second author on the third.
Here’s the retraction note for a paper that showed elderly adults with chronic hepatitis C are at risk of having cognitive issues:
Thanks to some eagle-eyed readers, we’ve been alerted to some corrections for high profile stem cell scientist Jacob Hanna that we had missed, bringing our count to one retraction and 13 errata on 10 papers.
The problems in the work range from duplications of images, to inadvertent deletions in figures, to failures by his co-authors to disclose funding sources or conflicts of interest. Hanna is the first or last author on 4 of the papers, and one of several on the rest.
First up, a correction to a Cell paper on which Hanna is the first author:
Community blog PLOS Biologue has pulled a post by journalists Charles Seife and Paul Thacker that argued in favor of public scrutiny of scientists’ behavior (including emails), following heavy criticism, including from a group and scientist mentioned in the post.
Their reasoning: The post was “not consistent with at least the spirit and intent of our community guidelines.”
The original post, published August 13, is no longer available online, but you can read it here. In the piece, Seife and Thacker lament what they call a recent backlash against transparency in science: Read the rest of this entry »
It may not be much of a surprise that narcissistic CEOs of pharmaceutical companies will make bold choices, such as adopting radically new technology. That idea remains true, despite a lengthy correction to a paper that supports it.
The paper, “CEO Narcissism, Audience Engagement, and Organizational Adoption of Technological Discontinuities,” in Administrative Science Quarterly, found support for the following hypothesis:
A correction to a correction is the latest problem for highly cited researcher Jacob Hanna. The stem cell scientist — whose high-profile work has received scrutiny over the past year — has amended an earlier correction notice after a reader spotted an inadvertent “mistake.”
We reported on the original correction, to the 2009 Cell Stem Cell paper “Metastable Pluripotent States in NOD-Mouse-Derived ESCs,” in July. The paper has been cited 184 times, according to Thomson Scientific’s Web of Knowledge.
Apparently, a pair of images in the original correction note are of the same cell colonies, when they are supposed to be of separate cell colonies.
The new (and detailed) note explains how that happened:
Authors of a widely covered study that documented traces of plague and anthrax on surfaces across New York City have revised the paper after public health officials challenged their interpretations of the data.
It’s hard to overestimate the attention these findings received when first published.
“Bubonic plague found in NYC subway,” wrote The Daily Beast.
“NY subway has bubonic plague,” declared Newser.
Olivier Voinnet — a plant researcher who was recently suspended for two years from the Centre national de la recherche scientifique (CNRS) after an investigation by
ETH Zurich and CNRS found evidence of misconduct — has issued his second retraction and two more corrections.
PNAS posted the retraction earlier this week for a 2006 article after an inspection of the raw data revealed “errors” in study images. Authors confirmed the issues in some figures and revealed “additional mounting mistakes” in others.
Voinnet has promised to issue retractions and corrections for every study that requires them. These latest notices bring our tally up to nine corrections, two retractions and one Expression of Concern.
A review paper that suggested the degenerative brain disease that’s striking former football players may not be tied to contact sports has been corrected to reveal the first author spent decades working for the National Football League.
The correction appears in a review in PLOS ONE about chronic traumatic encephalopathy – the degenerative brain disease that was the basis of a $765 million settlement for former NFL players, along with a number of similar lawsuits. It fixes incorrect statements and adds conflicts of interest, including those with with first author Joseph Maroon, who spent more than 30 years working with the NFL and seven for the wrestling group the WWE.
Cell biologist Jacob Hanna, the highly cited stem cell researcher currently at the Weizmann Institute of Science, has posted a long erratum for a 2005 paper in Blood for “inadvertent mistakes,” among other issues; soon after, Hanna’s team issued another erratum for a 2009 Cell Stem Cell paper.
There’s more to tell: Last month, commenters on PubPeer noticed that images from at least 10 of the research papers Hanna coauthored in seven journals — that commenters had posted on the image hosting website Imgur and linked to on PubPeer — had been deleted.
Imgur did not confirm whether these specific images had been deleted, but told Retraction Watch:
The author of “The Economic Effects of Climate Change,” Richard Tol, a professor of economics at the University of Sussex, blamed earlier problems with the paper on “gremlins.” In a notice posted last year, Tol wrote that “minus signs were dropped”; he also added a pair of “overlooked estimates” and several recently published studies.
After the first correction was published, several people contacted the JEP to point out more issues with the paper. Editors worked with Tol and outside researchers to update the paper again.
Here’s some text from the newest correction notice:
