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.
Researchers at a prominent Japanese university have retracted a 2015 paper in Science,after an investigation uncovered image falsification and fabrication.
Last September, the University of Tokyo began an investigation of seven papers from the lab of cell biologist Yoshinori Watanabe after receiving anonymous allegations. In May 2017, the university determined that five papers contained falsified or fabricated images, and announced the results of its investigation on August 1. Two of the papers were published in Science, two in Nature and one in EMBO Reports.
Recently, a biostatistician sent an open letter to editors of 10 major science journals, urging them to pay more attention to common statistical problems with papers. Specifically, Romain-Daniel Gosselin, Founder and CEO of Biotelligences, which trains researchers in biostatistics, counted how many of 10 recent papers in each of the 10 journals contained two common problems: omitting the sample size used in experiments, as well as the tests used as part of the statistical analyses. (Short answer: Too many.) Below, we have reproduced his letter.
When zoologists at the University of Oxford published findings in Science last year suggesting ducklings can learn to identify shapes and colors without training (unlike other animals), the news media was entranced.
However, critics of the study have published a pair of papers questioning the findings, saying the data likely stem from chance alone. Still, the critics told us they don’t believe the findings should be retracted.
If a duckling is shown an image, can it pick out another from a set that has the same shape or color? Antone Martinho III and Alex Kacelnik say yes. In one experiment, 32 out of 47 ducklings preferred pairs of shapes they were originally shown. In the second experiment, 45 out of 66 ducklings preferred the original color. The findings caught the attention of many media outlets, including the New York Times, The Atlantic, and BuzzFeed.
Science has retracted a high-profile immunology paper after a probe concluded the corresponding author had committed misconduct.
The paper — which initially caught media attention for suggesting a protein could help boost the immune system’s ability to fight off tumors — has been under a cloud of suspicion since last year, when the journal tagged it with an expression of concern, citing a university investigation.
That investigation — at Imperial College London — has concluded that the paper contained problematic figures that were the result of research misconduct. All were prepared by last and corresponding author Philip Ashton-Rickardt, who took full responsibility. Even though the paper was published in 2015, some original blots and accompanying details have disappeared.
The move comes after a group of researchers alleged the paper contains missing data, and the authors followed a problematic methodology. In September, however, the co-authors’ institution, Uppsala University in Sweden, concluded there wasn’t enough evidence to launch a misconduct investigation.
A high-profile plant scientist who has been racking up corrections and retractions at a steady clip has had another paper — this one from Science — retracted.
The retraction, of a paper that had been previously corrected, is the eighth for Olivier Voinnet. According to the notice, the correction did not address all the figure problems with the paper, which “cannot be considered the result of mistakes.”
An expert group at Uppsala University has recommended not proceeding with a full investigation into allegations of misconduct in a high-profile Science paper showing how human pollution may be harming fish.
