The Journal of the American Chemical Society has issued an expression of concern over “the presentation of results” in a 2014 paper about a new probe for use in imaging.
We haven’t heard back from the journal nor the authors of the paper, so there’s not much we can officially say about what the journal is investigating.
Here’s the text from the expression of concern:

The author of a pilot study that suggested adding spices may encourage people to eat more vegetables initially didn’t realize that her paper had been retracted from Food and Nutrition Sciences in May.
What’s more, Zhaoping Li, Chief of the Division of Clinical Nutrition at the University of California, Los Angeles and the first author on the paper, didn’t realize the reason for the retraction: The journal had mistakenly published her paper twice, and had to retract the second copy. The first remains published.
This was entirely the journal’s mistake, editor Alessandra Bordoni told us:

Stefan Franzen doesn’t give up. Ten years ago, he began to suspect the data behind his colleagues’ research about using RNA to make palladium nanoparticles, a potentially valuable tool that ended up as a Science paper. Recently, the National Science Foundation (NSF) decided to cut off funding for Bruce Eaton and Dan Feldheim — currently at the University of Colorado at Boulder — and last week, Science retracted the paper. We talked to Franzen, based at North Carolina State University (NCSU), about his decade-long efforts, and how it feels to be finally vindicated.
Retraction Watch: How did you first begin to suspect the findings by Eaton and Feldheim?
Stefan Franzen: Starting in early 2005, I was collaborating with Drs. Eaton and Feldheim at NCSU, thanks to two joint grants from the W.M. Keck Foundation and NSF. During a group meeting in December of 2005, a graduate student showed electron microscopy data that were inconsistent with the assignment of the particles as palladium. Over time, we kept producing more data that called their findings into question; in April 2006, a postdoc showed that the hexagonal particles could be obtained without RNA. By then, I could see that there was a significant discrepancy between what was written in the articles and what was done and observed in the laboratory.
RW: How did you report your concerns?

Researchers in Finland are criticizing an investigation by VTT Technical Research Centre into one of its scientists.
The investigation followed allegations about the VTT’s plasma and serum metabolomics (QBIX) group, previously led by Matej Orešič (who is now based at the Steno Diabetes Center in Gentofte, Denmark) and Tuulia Hyötyläinen. Kai Simons, who conducted an earlier investigation of the group, and the Chancellor Emeritus at the University of Helsinki, have criticized VTT, saying it cut corners in its investigation.
VTT found no evidence of data tampering or falsification in a 2008 paper co-authored by Orešič in the Journal of Experimental Medicine, but said the paper — which has not been corrected or retracted — included some “exaggerated conclusions.” In turn, Orešič and Hyötyläinen filed a complaint for “an alleged violation of good scientific practice” by Simons during the initial investigation.

A chemist is suing the University of Texas a second time in an effort to keep the PhD she earned in 2008.
In 2014, school officials revoked Suvi Orr‘s degree after finding it was based, in part, on falsified data. Some of the data were also included in a paper in Organic Letters that was retracted in 2011 after some steps in the chemical synthesis the authors described were not reproducible. Orr, currently working at Pfizer, sued UT, and the school reinstated her degree.
Now, the school is trying to remove it again, according to the lawsuit, filed last week. The lawsuit says the school has scheduled a “hearing” on March 4, during which three undergraduate students and two faculty members will deliberate — “none of whom are qualified to evaluate the scientific evidence being used against S.O.,” the suit says.
Orr has requested a temporary injunction to halt the proceedings, and a hearing has been scheduled for next week, according to the Austin-American Statesman.
The suit argues the school does not have the right to strip Orr’s degree from her: Continue reading Chemist sues University of Texas (again) to keep PhD
Would designating a set of authors as responsible for data production – separate from those who conduct the analysis – help boost the reliability of papers? That’s a question raised by the editor of the New England Journal of Medicine, Jeffrey Drazen. Along with many other editors of top medical journals, Drazen recently signed a proposal by the International Committee of Medical Journal Editors to require authors of clinical trials to share anonymous patient data within six months of publication. He talked to us about another way to make trials more robust: Create “data authors.”
Retraction Watch: What has been the reaction so far to ICMJE’s data sharing proposal? Continue reading Should there be “data authors?” Q&A with NEJM editor Jeffrey Drazen
A group of authors published two articles about one study on pain during childbirth, so one journal is retracting it.
This may seem like a standard case of salami slicing — but this one comes with a nearly 600-word commentary co-authored by the editors of the two journals in question.
The commentary lays out — in a refreshingly transparent way — exactly why the journals came to a joint decision to retract one of the papers:

A psychiatric journal has pulled a 2014 paper that found electroconvulsive therapy and exercise helped people with depression, after the authors determined they had mistakenly analyzed the wrong data.
According to the retraction notice from the Journal of Psychiatric Research, the researchers had “erroneously analyzed” data from a previous study they had published the year before.
Here’s more from the note for “Electroconvulsive therapy and aerobic exercise training increased BDNF and ameliorated depressive symptoms in patients suffering from treatment-resistant major depressive disorder:” Continue reading Authors used wrong dataset in study on shock therapy, exercise in depression
A paper flagged in an Office of Research Integrity notice more than one year ago has finally been retracted. According to the notice, the paper includes images manipulated by author H. Rosie Xing, a former University of Chicago cancer researcher.
The main conclusions of the paper are affected by the ORI finding, according to the retraction note from Molecular Cancer Therapeutics. But otherwise, the note contains information that was available in the ORI finding, published in December 2014.
“Pharmacologic Inactivation of Kinase Suppressor of Ras1 Sensitizes Epidermal Growth Factor Receptor and Oncogenic Ras-Dependent Tumors to Ionizing Radiation Treatment” has been cited seven times, according to Thomson Scientific’s Web of Knowledge — twice since the ORI finding came out.
The retraction note explains which images were affected by the manipulation:

The secretary general of the Nobel Assembly, the body responsible for choosing the Nobel Prizes, has resigned from his post because “he may be involved” in the Karolinska Institutet investigation of trachea surgeon Paolo Macchiarini.
Urban Lendahl, professor of genetics at the Karolinska, has also resigned as secretary general of the Nobel Committee in Physiology or Medicine. Here’s a statement released yesterday by the Nobel Assembly: Continue reading Nobel Prize official resigns in wake of Macchiarini case
