A physics journal has retracted a 2014 paper after a reader discovered a slew of errors.
The paper, published in the Journal of Thermophysics and Heat Transfer, explored how the properties of nanofluids—fluids that contain nanoparticles—change as the fluid moves through different materials.
According to the editor-in-chief, Greg Naterer, an outside expert—Asterios Pantokratoras, based at Democritus University of Thrace in Greece—contacted the journal in May 2017 after discovering “errors with symbols in equations and figures.” The journal investigated the concerns and reached out to the paper’s corresponding author V. Ramachandra Prasad at Madanapalle Institute of Technology and Science in India for a response; after several rounds of comments from Pantokratoras and Prasad, the journal concluded that the paper should be retracted.
A journal is planning to retract a paper that purported to link a component of vaccines to autism in mice.
The paper, about the effects of aluminum adjuvants in vaccines on the immune response in the brains of mice, is the second retraction for co-authors Christopher Shaw and Lucija Tomljenovic, of the University of British Columbia. The journal’s editor told us he and the authors are jointly retracting the paper.
Just over a month old, the paper has already received plenty of criticism. Numerous commenters on PubPeer have allegedly identified image duplications and other problems with the paper. One commenter described “clear and deliberate” removal of control results in the paper, while others suggested gel bands were duplicated within the paper, and appear similar to those from another paperpublished in 2014 by Shaw and Tomljenovic. In a blog post, David Gorski, a professor and surgeon at Wayne State University, called the paper “antivaccine pseudoscience.”
The retracted paper — a 2012 research letter in the Archives of Pediatrics and Adolescent Medicine, now JAMA Pediatrics — reported that children were more likely to choose an apple over a cookie if the apple included an Elmo sticker. The same day the paper was retracted, Wansink and his co-authors published a replacement version that includes multiple changes, including to the methodology and the results.
The retraction notice lists the mistakes, which the authors say they made “inadvertently:”
On Friday, BMC Nutrition posted a brief notice about the 2015 paper, which examined whether people who pay different amounts for all-you-can-eat Italian buffets feel more or less guilty about how much they ate. The notice says the retraction stems from concerns about the data analysis, and the authors do not agree with the journal’s decision.
The new retraction is the second for Wansink, director of the Food and Brand Lab at Cornell.
Science has issued an expression of concern for a widely covered materials science paper published on Friday, citing issues with the supplementary data.
The paper — which caught the attention of multiple news outlets — added properties to cotton fibers in vitro, potentially enabling researchers to manufacture fabric that can fluoresce or carry magnetic properties.
The move to issue an expression of concern was unusually quick. According to the journal, an expert who received the paper from a journalist under a media embargo contacted Science to flag issues in some of the supplementary data. At the time of this post, the paper does not yet have an entry on PubPeer.
