The Journal of Anatomy has expressed concern about a 2011 paper on primate jaws.

Articles, like lawn furniture, aren’t supposed to rust after just two months. But the Journal of Materials Chemistry A has issued an Expression of Concern for a February 2014 paper by a group of chemists from India over possible problems with several figures in the article.
The paper, “Hierarchically macro/mesostructured porous copper oxide: Facile synthesis, Characterization, Catalytic performance and Electrochemical study of mesoporous copper oxide monoliths,” was written by Gowhar Ahmad Naikoo, of the department of chemistry at Dr. Hari Singh Gour Central University, in Sagar, and two colleagues. It purported to find that:

On Tuesday, we broke the news of the retraction in Circulation of a paper on cardiac stem cells by a group of researchers being investigated by Harvard Medical School and the Brigham and Women’s Hospital. Today, The Lancet has issued an Expression of Concern about another paper led by Piero Anversa, the last author of the Circulation paper.
Sometimes, an Expression of Concern says a heck of a lot without — as befits the genre — coming to a particular conclusion. Take this (paywalled)* example describing a paper from a group at Huazhong Science and Technology University, Wuhan, China: Continue reading Expression of Concern reveals journal editors bending over backward to give authors benefit of the doubt
Neuroskeptic featured an interesting situation over the weekend, involving a case report published in an anesthesiology journal.

Neurology has issued an expression of concern over a 2013 article by a group of scientists in The Netherlands and the United States who found a potentially devastating error in their analysis.
The article, “Structural and functional brain connectivity in presymptomatic familial frontotemporal dementia,” came from the lab of John C. van Swieten, of Erasmus University in The Netherlands. According to the abstract of the article: Continue reading Neurology expresses concern over dementia study after authors report error in analysis
In yesterday’s Weekend Reads, we highlighted a piece by Hope Jahren explaining why she wouldn’t agree to a Q&A with Nature. We found out after Weekend Reads had posted that the story had moved on, so here’s an update.
Jahren was objecting — as did a number of people — to a letter published in Nature earlier in the week by Lukas Koube of Sherman, Texas, which began: Continue reading Nature apologizes for publishing letter dismissing need for gender balance
A group at the University of Texas Southwestern that retracted five papers last year has retracted one more, and has had a paper subjected to an Expression of Concern at the request of the school’s dean.
Here’s the retraction notice for “DNA methylation-associated inactivation of TGFβ-related genes, DRM/Gremlin, RUNX3, and HPP1 in human cancers,” originally published in the British Journal of Cancer and cited 51 times, according to Thomson Scientific’s Web of Knowledge:

The Journal of Bone and Joint Surgery has issued an expression of concern about a paper whose authors may not have obtained proper ethical clearance.
Here’s the notice, signed by editor in chief Vernon Tolo: Continue reading Lack of ethical clearance prompts expression of concern from bone journal
A strange tale is brewing at a journal that has been shuttered since August of last year, which will lead to some 40 expressions of concern.
There are a number of threads to tie together here, so bear with us for a moment. First, BioMed Central, the publisher of Head & Neck Oncology, posted this statement on the journal’s homepage today: Continue reading Head-spinning: Publisher to post dozens of notices of concern following investigations into editors in chief
