Fraud fells Alzheimer’s “made to order” neurons paper in Cell

cell414In 2011, a group of researchers at Columbia University reported in Cell that they had been able to convert skin cells from patients with Alzheimer’s disease into functioning neurons — a finding that raised the exciting prospect of “made to order” brain cells for patients with the degenerative disease. As one researcher not involved with the study, led by Asa Abeliovich, put it:

“[This is] simply a remarkable and complete piece of work which will now set a standard for stem cell work in neurological disease. The standard of the characterization of the neuronal cultures is very high,” John Hardy at University College London, U.K., wrote to [Alzforum]. He was not involved in the work but is taking a similar approach in his own lab.

According to the abstract of “Directed Conversion of Alzheimer’s Disease Patient Skin Fibroblasts into Functional Neurons:”

Following “personal attacks and threats,” Elsevier plant journal makes author persona non grata

Scientia HorticulturaeAn Elsevier journal has taken “the exceptional step of ceasing to communicate” with a scientist-critic after a series of “unfounded personal attacks and threats.” The move means that the journal, Scientia Horticulturae, will not review any papers that include the critic, Jaime A. Teixeira da Silva, as an author.

Here is the text of the letter (pdf here, obtained from an anonymous source), signed by Gert Jan-Geraeds:

Lack of citation prompts correction in Nature journal

nature communicationsIt’s not unusual to hear authors bemoan the fact that a new paper doesn’t cite their work that set the stage for a scientific advance. “The journal limited me to [a seemingly abitrary number of] references,” authors sometimes shrug, with or without apology. This week, however, we found a case of that which seems to have been resolved to everyone’s satisfaction.

The authors of a September 2013 article in Nature Communications have issued a correction for the piece, which failed to cite the source of a key step in their experiment.

The article, “Val66Met polymorphism of BDNF alters prodomain structure to induce neuronal growth cone retraction,” came from the lab of William “Clay” Bracken, a biochemist at Weill Cornell Medical College. According to the abstract: Continue reading Lack of citation prompts correction in Nature journal

Harvard and the Brigham investigating leading heart group for “compromised” data

circulationcoverCirculation has retracted a 2012 study by a group of Harvard heart specialists over concerns of corrupt data, and the university is investigating. The group was led by Piero Anversa, a leading cardiologist, and Joseph Loscalzo — who will be familiar to readers of Circulation as the editor in chief of that journal. (Anversa’s also on the editorial board).

Pain study retracted for bogus data is second withdrawal for University of Calgary group

molpainBack in January 2013, we wrote about the retraction of a paper in Diabetes that the authors had “submitted without knowledge of inherent errors or abnormalities that they recognized in retrospect after submission.”

Now, Molecular Pain has retracted a paper by the same authors, this time for data manipulation. The article, “Comparison of central versus peripheral delivery of pregabalin in neuropathic pain states,” was written by Cory Toth, a clinical neuroscientist at the University of Calgary, in Canada, and colleagues. It has been cited eight times, according to Thomson Scientific’s Web of Knowledge.

Toth said of the Diabetes article at the time:
