According to the notice, the senior author told the journal that the data came from the lab Li used to work in at the University of Rome Tor Vergata, but the P.I. in Italy didn’t know about the paper.
The initial paper concluded that their modified gene produced a Cry protein that was significantly more toxic than the one currently spliced into food crops to make them resistant to moths, beetles, and other insects. However, when repeating the experiments, the modified proteins weren’t any more deadly than the original version.
For one, many of the images were copied from another paper. In addition, one of the authors did not disclose that he was the president of a related company, nor that his company provided reagents for the experiments.
It’s not clear when the paper was published, but The paper was published on October 16, 2014, and a withdrawal notice went up on January 16, 2015. Here’s the retraction for “Enhanced Detection and Phenotypic and Karyotypic in Situ Characterization of Circulating Tumor Cells”: Read the rest of this entry »
The article, by authors from Peking Union Medical College in China, Yale University, and elsewhere, presented the results of the China PEACE-Retrospective Acute Myocardial Infarction Study, part of a national initiative to study and improve care for cardiac problems. After being posted online on June 24, 2014, the authors noticed that they’d incorrectly weighed one of the cities in their calculations, which threw off a number of national estimates.
After the corrections were made, the paper was peer-reviewed again, and reviewers stated that despite the mistakes, the original conclusions were sound.
Today is a banner day on Retraction Watch: This is our second excellent example of transparency in 24 hours, and therefore the second entry in our “doing the right thing” category. An editorial lays out exactly what happened, including a timeline, allowing scientists to feel confident they’re basing the next research step on solid and accurate data. (We also appreciate the hat tip to the Committee on Publication Ethics retraction guidelines, which we often send out to editors of bad notices as a gentle reminder.)
Here’s the notice for “ST-segment elevation myocardial infarction in China from 2001 to 2011 (the China PEACE-Retrospective Acute Myocardial Infarction Study): a retrospective analysis of hospital data”: Read the rest of this entry »
Quantum communication involves sending a series of photons in specific quantum states over fiberoptic cables. It’s a little like the 1s and 0s of traditional computing, but much more secure. If the photons are intercepted on their way to the intended target, the quantum states will change, and the recipients can know their information was accessed by other parties. This is especially interesting to governments with a lot of secret information to transmit: both China and the U.S. have programs to develop these networks.
The retracted paper was a discussion of how to efficiently send lots of quantum information from different sources through the same fiberoptic cables at once.
We keep a list of best euphemisms for plagiarism, and this one is right up there.
The group has decided to repeat the experiments on their own next time.
Here’s the notice in Molecular Medicine Reports for “Protective role of Klotho on cardiomyocytes upon hypoxia/reoxygenation via downregulation of Akt and FOXO1 phosphorylation”: Read the rest of this entry »
A group of Chinese cardiologists at Capital Medical University have done a quick ewe-turn, pulling a paper after mixing up both the author order and wrongly reporting how many sheep were killed in the making of this experiment.
We covered another retraction from the CMU cardiology department in September. The sheep paper was published in October.
The number of papers retracted for fake peer reviews — well in excess of 100, by our count — continues to grow.
The latest to join the list are “Rebamipide plus proton pump inhibitor versus proton pump inhibitor alone in treatment of endoscopic submucosal dissection-induced gastric ulcer: a meta-analysis of randomized controlled trials” and “Association study of TGFBR2 and miR-518 gene polymorphisms with age at natural menopause, premature ovarian failure and early menopause among Chinese Han women,” both published in 2014 in Medicine.
