Questions about the work, and other articles on which Hanna was an author, were raised on PubPeer last November. This is his first retraction.
The retraction stems from “a number of figure irregularities;” the authors say they were “inadvertently introduced,” and subsequent work has supported their data and conclusions. However, due to the “number of serious mistakes,” the JCI editorial board chose to retract the article. Hanna and corresponding author Ofer Mandelboim at The Lautenberg Center for General and Tumor Immunology — part of Hebrew University, in Jerusalem, where Hanna used to work — say they have accepted the decision.
Hanna, currently at the Weizmann Institute of Science, studies ways to reprogram cells to become more versatile stem cells. He also spent time as a postdoc at the Whitehead Institute in Cambridge and Mount Sinai, in New York City.
Six of Hanna’s papers have been cited more than 500 times, according to Thomson Scientific’s Web of Knowledge. The most-cited, with more than 1,000 citations, was a 2008 Nature paper.
The retracted article, “Novel APC-like properties of human NK cells directly regulate T cell activation,” has been cited 121 times, according to Thomson Scientific’s Web of Knowledge.
The retracted paper examined the early steps of an immune response involving natural killer (NK) cells and antigen-presenting cells (APCs). From the abstract: Read the rest of this entry »

A group of materials researchers at Solapur University in India have lost a paper because they submitted an identical manuscript to two journals. Both journals published the paper, though only one has retracted it.
Taylor and Francis journal Journal of Experimental Nanoscience retracted the 2012 paper in February this year; the notice doesn’t explain the delay, or how the editors learned about the overlap.
The retraction indicates the editor of the journal that published the other version of the paper was informed of the overlap, but the journal — – Journals of Materials Science: Materials in Electronics — has not issued a retraction.
According to the notice, it was two authors of the retracted paper themselves who pointed out the overlap. The first author, Pratap Sahoo, is not mentioned, although it does say all three authors agreed to retract. The corresponding author of the original paper told us he was unaware of the incident.
You can compare the figures for yourself – on the left is figure 6(a) from the retracted Materials Research Express paper, rotated 90 degrees. On the right is figure 4(e) from “Porous Au Nanoparticles with Tunable Plasmon Resonances and Intense Field Enhancements for Single-Particle SERS,” published in the Journal of Physical Chemistry Letters: Read the rest of this entry »
A paper on apoptosis in mice has been retracted by Infection and Immunity after a reader tipped them off that several figures were “not faithful representations of the original data.”
When the journal, published by the American Society for Microbiology (ASM), contacted the authors at Anhui Medical University in Hefei, China, they claimed they couldn’t provide the experimental data thanks to “damage to a personal computer,” said Ferric Fang, editor of the journal and a member of the board of directors of the Center for Scientific Integrity, Retraction Watch’s parent organization. Seven figures in total were compromised, including several that were duplicated throughout the article.
Here’s the notice for “Reactive Oxygen Species-Triggered Trophoblast Apoptosis Is Initiated by Endoplasmic Reticulum Stress via Activation of Caspase-12, CHOP, and the JNK Pathway in Toxoplasma gondii Infection in Mice”: Read the rest of this entry »
The article, “Bayesian inference for quantifying Listeria monocytogenes prevalence and concentration in minced pork meat from presence/absence microbiological testing,” came from a group at the Department of Food Science and Technology at the Agricultural University of Athens, in Greece.
The article, “Dynamic nature of washback on individual learners: the role of possible selves” in Assessment & Evaluation in Higher Education, is about how taking a major English test influenced learning in Chinese undergraduate students. Author Ying Zhan is listed at Guangdong University of Foreign Studies, in mainland China; Zhi Hong Wan, at the Hong Kong Institute of Education.
The article, “The influence of sand diameter and wind velocity on sand particle lift-off and incident angles in the windblown sand flux,” appeared in the May 2013 issue of Sedimentary Geology. It was written by a team from the Key Laboratory of Mechanics on Western Disaster and Environment at Lanzhou University.
In 1932, Einstein famously retracted his “cosmological constant.” Now, more than 80 years later, a Brazilian healthcare journal bearing his name has retracted its first paper.
The authors of the review, about the effects of neuromuscular electrical stimulation in hospitalized patients on ventilators, appear to made the genius move of trying to publish their paper in two different journals at once.
According to the notice, the 2014 paper — about the best ways to set up manufacturing cells in the automobile industry — “is almost entirely taken” from a Durham University, UK student’s PhD thesis. The thesis, “Computer-aided design of cellular manufacturing layout,” was written by Yue Wu. We were unable to track him down after he left the University of Exeter‘s Manufacturing Enterprise Center.
