The Veterinary Journal has retracted a 2014 paper that found that sheep eat more when their food is supplemented with urea (yes, the same compound found in urine).
The notice was published after a “complaint which raised serious concerns.”
Here’s more from the notice:
A group of authors is retracting a paper from Structure following a Brandeis University investigation that found the first author had fabricated a key result.
Former graduate student Kelsey Anthony was first author of the paper, “High-Affinity Gold Nanoparticle Pin to Label and Localize Histidine-Tagged Protein in Macromolecular Assemblies, which was published online in February 2014. At the time, the Science at Brandeis blog noted: Continue reading Brandeis investigation finds scientific misconduct in gold nanoparticle paper
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 evaluate how the material holds up.
According to the retraction note for the paper, imaging performed by a third party “may not be trustworthy.”
The paper has been cited 42 times, according to Thomson Scientific’s Web of Knowledge.
Here’s more from the retraction note to “Nano-structure and mechanical properties of 0–7 strained aluminum by CGP: XRD, TEM and tensile test“:

Retractions have been published for four papers authored by former Wayne State University professor, Teresita L. Briones, after an April ORI report found evidence of misconduct in the articles.
Investigators found that Briones had “intentionally, knowingly, and recklessly engaged in research misconduct by falsifying and/or fabricating data.” They flagged five papers and three grant applications that contained false data.
As a result of their findings, four out of the five papers have been retracted, and the editors of the remaining journal say they are looking into the last paper.

A third retraction — and a notice of concern — have emerged from the investigation into a husband and wife research team at the University of Toronto that found evidence of faked images and duplicated data.
The problem, according to the latest retraction note for Sylvia Asa and Shereen Ezzat, in the Journal of Clinical Investigation: Portions of the RT-PCR gels “are duplicated in this publication and in a subsequent publication.” That subsequent publication is a 2003 paper that has received a Notice of Concern from the American Journal of Pathology.
According to the retraction note, co-author Gillian E. Wu of York University signed off on the journal’s decision, but Asa, Ezzat and second author Lei Zheng dissented to the retraction. Third author Xian-Feng Zhu couldn’t be reached. Although corresponding author Asa noted that “the initial screen of these samples support the conclusions made in the paper,” the JCI made its position perfectly clear in the note:

Authors of a widely covered study that documented traces of plague and anthrax on surfaces across New York City have revised the paper after public health officials challenged their interpretations of the data.
It’s hard to overestimate the attention these findings received when first published.
“Bubonic plague found in NYC subway,” wrote The Daily Beast.
“Your subway seat mate: Bubonic plague, anthrax, & mysterious DNA,” said Yahoo!
“NY subway has bubonic plague,” declared Newser.
Not so fast. In an erratum published July 29, the authors write: Continue reading Plague or anthrax on the subway? Think again, says now-corrected study
A paper on how abnormal stem cells can cause benign bone tumors has been retracted by Cell Stem Cell after an inquiry into image duplications also uncovered “multiple instances of inappropriate western blot image adjustment.”
The first two authors “declined” to sign the retraction, according to the notice.
Besides confirming initial suspicions that images had been duplicated, the editors also found “multiple instances of inappropriate western blot image adjustment, such as uneven compression of images and removal of background elements:”

A prominent endocrinologist pathologist has resigned from running the largest hospital diagnostic laboratory in Canada following an investigation that has uncovered evidence of falsified data in two papers, Retraction Watch has learned.
Sylvia Asa was the Program Medical Director of the Laboratory Medicine Program at the University Health Network, affiliated with the University of Toronto, until this past spring when she stepped down, according to UHN spokesperson Gillian Howard:

Microporous and Mesoporous Materials has retracted a 2015 paper after it was discovered the authors “have plagiarized part of a paper that had already appeared.”
The paper, “Ionic liquid assisted synthesis of flexible and super-hydrophobic porous gels,” described the synthesis of a form of flexible aerogels “through a facile one-pot preparation,” according to the abstract. According to Thomson Scientific’s Web of Knowledge it has been cited zero times.
Here is the retraction note, in full:

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 on PubPeer noticed that images from at least 10 of the research papers Hanna coauthored in seven journals — that commenters had posted on the image hosting website Imgur and linked to on PubPeer — had been deleted.
Imgur did not confirm whether these specific images had been deleted, but told Retraction Watch:
