In 1932, Einstein famously retracted his “cosmological constant.” Now, more than 80 years later, a Brazilian healthcare journal bearing his name has retracted its first paper.
The authors of the review, about the effects of neuromuscular electrical stimulation in hospitalized patients on ventilators, appear to made the genius move of trying to publish their paper in two different journals at once.
It hasn’t been a good week for scientists going to court to silence criticism of their work.
Yesterday, PubPeer won a near-complete victory in a case seeking the identities of their commenters. And also yesterday, a Massachusetts judge struck down — for the second time — a request by Mario Saad to remove expressions of concern about four of his papers in Diabetes.
PLoS ONE has just issued a 12-figure correction on a paper by Mario A. Saad, who sued the American Diabetes Association unsuccessfully in an attempt to prevent it from retracting four papers in its flagship journal Diabetes.
The corrections include taking out Western blots copied from another Saad paper, as well as several figures where the bands were “misplaced.”
American Diabetes Association 1, Mario Saad 0.
As reported by the National Law Journal, a federal judge in Boston has denied Saad’s requests to stop the ADA’s flagship journal, Diabetes, from publishing expressions of concern about four of Saad’s papers, and to prevent the journal from retracting the studies.
Saad filed suit against the ADA on February 5. Judge Timothy Hillman wrote in his order yesterday that approving the researcher’s motion would have violated the right to free speech: Read the rest of this entry »
Several journals have retracted or corrected papers from a group at State University of Maringá in Brazil over what one chemistry journal calls “fraudulent use” of figures previously published by the authors.
Química Nova, which is retracting a 2013 paper, issued a notice that taps an additional eight articles with Angelica Lazarin as the corresponding author that reused figures. Specifically, the papers included images “where same trace on the figure was assigned to different conditions and/or compounds.”
A number of the papers mentioned in the Química Nova notice were co-authored by Claudio Airoldi, whose group retracted 11 papers in 2011 following concerns over fraudulent nuclear magnetic resonance images.
State University of Campinas University of Campinas and the American Diabetes Association disagree strongly over how to handle disputed images from faculty member Mario Saad, who is suing the ADA to prevent retraction of his papers.
State University of Campinas University of Campinas (Unicamp) acknowledges that 2 of Saad’s papers contain “mistakes”, it concluded there was “not an intention in the actions of the authors,” and the mistakes did not have a negative impact on the scientific community. Ultimately: “the studies published have their own strength, are healthy and were not artificially strengthened by the incorrect images.”
In response, however, Saad’s lawsuit says the ADA asked the school to reinvestigate the articles, and refused to accept any papers from Unicamp faculty in any ADA journals until the issues are resolved.
The ADA has issued four expressions of concern in Saad’s research published in its flagship journal, Diabetes. Saad’s lawsuit aims to prevent the journal from retracting those papers, and asks for monetary compensation.
Here is an excerpt from the Unicamp’s findings: Read the rest of this entry »
As reported in the Boston Business Journal, Saad’s lawsuit claims that his institution, the State University of Campinas, investigated two articles at the journal’s behest. The American Diabetes Association was unhappy with the results, and asked the school to reopen the investigation, including two additional papers.
Saad is suing to prevent the journal from retracting the papers, in addition to monetary compensation.
The reason: Image manipulation — which the authors say didn’t materially affect the conclusions of the paper.
The article, “FAK mediates the activation of cardiac fibroblasts induced by mechanical stress through regulation of the mTOR complex,” came from a group led by Ana Paula Dalla Costa, from the State University of Campinas.
We spoke with International Journal of Biometeorology editor-in-chief Scott Sheridan about the case: Read the rest of this entry »
A missed withdrawal request has led to doubled up publication and a later retraction for Brazilian physicists, through no fault of their own.
“Atmospheric Plasma Treatment of Carbon Fibers for Enhancement of Their Adhesion Properties” was presented at an Institute of Physics (IOP) conference in 2010. The proceedings weren’t published until May 2014.
In the meantime, the plasma scientists withdrew their paper from consideration and submitted it to IEEE Transactions on Plasma Science, where it was published in February 2013. Unfortunately, in the four year delay between the conference and the Institute of Physics publication, the withdrawal request got lost.
