Mega-correction to several images in gastric cancer study

A journal has issued a rather large correction — what we call “mega-correction” — to a 2014 paper on a gastric cancer biomarker that fixes problems with several of the study’s figures. The authors write that despite the corrections, “the results and conclusions put forth in the article remain unchanged.” The paper, “TMEFF2 Deregulation Contributes to Gastric Carcinogenesis … Continue reading Mega-correction to several images in gastric cancer study

University investigating duplicated images in retracted paper

The authors of a Cell Metabolism paper are pulling it after discovering blot images that “appear more than once in independent and unrelated experiments.”  Just how the duplication occurred in the 2009 paper — about transcription of mitochondrial DNA — remains a mystery, the authors note: …the reasons for the errors are still under investigation… Meanwhile, … Continue reading University investigating duplicated images in retracted paper

Images “may not be trustworthy”: Aluminum sheets paper folds into retraction

Following questions “about the integrity of the microscopy images,” Materials Science and Engineering: A has retracted a paper on the properties of sheets of aluminum under strain. The images in question show sheets after a few rounds of a process called “constrained groove pressing,” which smushes sheets between two grooved plates, and then between two flat plates, to … Continue reading Images “may not be trustworthy”: Aluminum sheets paper folds into retraction

Cell biologist Hanna issues two errata; images mysteriously disappear from Imgur

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 … Continue reading Cell biologist Hanna issues two errata; images mysteriously disappear from Imgur
