Physicists with retraction for a “pattern that was unphysical” lose another for manipulation

journal of applied physicsIn September, we wrote about the retraction of a physics paper for “a pattern that was unphysical.”

The team, whose first author, R.K. Singhal refused to sign the notice, has had another paper retracted, this one in the Journal of Applied Physics. Here’s the notice for “Study of electronic structure and magnetization correlations in hydrogenated and vacuum annealed Ni doped ZnO:” Continue reading Physicists with retraction for a “pattern that was unphysical” lose another for manipulation

RIKEN inquiry prompted by STAP stem cell controversy generates three corrections

rikenlogo_enA review of past publications by the Japanese research institution RIKEN has produced three corrections of articles by a molecular geneticist, Haruhiko Koseki, The Scientist is reporting. The articles had appeared in Molecular and Cellular Biology between 2005 and 2010.

The review was triggered by the scandal involving Haruko Obokata, a former RIKEN scientist whose work on STAP stem cells has come under scrutiny. However, RIKEN officials said the corrections are unrelated to the Obokata case. Obokata has reportedly agreed to retract two of her articles in Nature. (RIKEN has released an English-language translation of its response to Obokata’s appeal against charges of research misconduct.)

According to The Scientist, Koseki was a member of a committee charged with investigating Obokata’s STAP results: Continue reading RIKEN inquiry prompted by STAP stem cell controversy generates three corrections

Cancer genetics group retracts three papers for “inappropriate presentation of data”

jbc 620A group of cancer genetics researchers in Italy and the U.S. has retracted three papers in the Journal of Biological Chemistry (JBC) after it became aware they had duplicated some bands in their figures.

Here are the three papers: Continue reading Cancer genetics group retracts three papers for “inappropriate presentation of data”

Contaminated cells force retraction of Blood paper

blood414Blood has an interesting retraction of a 2011 paper on what a group of authors claimed was a new cell line — but which proved, apparently, to be a chimera.

The article, “Oxygen-regulated expression of the erythropoietin gene in the human renal cell line REPC,” came from a team at Universität Duisburg-Essen, in Germany, and has been cited 21 times, according to Thomson Scientific’s Web of Knowledge. Here’s the abstract: Continue reading Contaminated cells force retraction of Blood paper

University of Maryland researchers notch second retraction

jbc 42514Two researchers at the University of Maryland who retracted a paper earlier this year for a duplicated figure have withdrawn another, this time for unknown reasons.

The Journal of Biological Chemistry (JBC) paper has been cited 16 times, according to Thomson Scientific’s Web of Knowledge.

Here’s the notice, for “Hsp90 Interaction with INrf2(Keap1) Mediates Stress-induced Nrf2 Activation,” which is unfortunately a return to the JBC’s opacity: Continue reading University of Maryland researchers notch second retraction

Authors retract study suggesting magnesium prevents Alzheimer’s in mice

j neuroscienceThe authors of a 2013 Journal of Neuroscience study suggesting that “elevation of brain magnesium…may have therapeutic potential for treating [Alzheimer’s disease] in humans” have retracted it after finding errors in the work.

Here’s the original abstract:

Doing the right thing: Physicists retract paper after becoming aware of “a fundamental error”

prl-bannerThe authors of a paper in Physical Review Letters have retracted it, after another researcher pointed out a mistake.

F. Sattin and D.F. Escande write in the notice for “Alfvénic Propagation: A Key to Nonlocal Effects in Magnetized Plasmas” (which is behind a paywall) that after the paper was published, they “we became aware of a fundamental error in the normalization of our equations.” Excerpt: Continue reading Doing the right thing: Physicists retract paper after becoming aware of “a fundamental error”

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).

Novartis Diovan scandal claims two more papers

diabetes careA complicated story involving Novartis’s valsartan (Diovan) has led to the retraction of two more papers, one cascading from the other.

Last September, The Lancet retracted the Jikei Heart Study after a slew of retractions of related work prompted an investigation of valsartan research. That investigation found evidence of data manipulation and the failure of one researcher to note his Novartis affiliation. The company has apologized.

Here’s one retraction, from Diabetes Care, for “The Shiga Microalbuminuria Reduction Trial (SMART) Group. Reduction of Microalbuminuria in Patients With Type 2 Diabetes: The Shiga Microalbuminuria Reduction Trial (SMART):”
