After 10 years, a whistleblower is vindicated. Here’s why he kept going.

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?

Chemist sues University of Texas (again) to keep PhD

Screen Shot 2016-02-08 at 4.34.25 PMA 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 Some of the data were also included in a paper in Organic Letters that was retracted in 2011 after some steps in the chemical synthesis the authors described were not reproducible.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

After hesitating, Science retracts chemistry paper against authors’ wishes

F1.mediumToday, Science has retracted a 2004 paper that’s been under scrutiny for years, despite the authors’ objections.

This paper has a long backstory: Recently, a report from the National Science Foundation’s Office of Inspector General surfaced that announced the agency had cut off the authors from funding. Last month, editor Marcia McNutt told us that the journal planned to retract the paper as soon as possible. Then, on January 21st, “just as we were going to press with the retraction,” said McNutt, the authors submitted a correction, which Science wanted to take some time to consider.

Now, the paper has a retraction note, against the wishes of authors Bruce Eaton and Dan Feldheim, currently at the University of Colorado.

Here it is the retraction note:

Data irregularities force author to retract three solar cell papers

An engineer has retracted three papers on a method for making nanoscale materials that are useful in solar cells.

The papers, all published in ACS Applied Materials & Interfaces, contain irregularities in data, and one includes images “which have been published elsewhere and identified with different samples,” according to the note.

The first author on all three papers is Khalid Mahmood, who — according to the bio from a talk he gave last year on efficient solar cells — is currently a postdoc at King Abdullah University of Science and Technology in Saudi Arabia. He did the work in the retracted papers while a student at the Korea Advanced Institute of Science and Technology, where, according to the bio, he completed his PhD in two years.

Here’s the retraction note for the first paper (which also contains a typo in the title — “electrospay”)

You’ve been dupe’d: Data so nice, you see them twice

j repro infertLast Friday we resurrected a previous feature of Retraction Watch, compiling five retractions that appeared to be simple acts of duplication.

This week, we spotlight another five unrelated retractions which, as we said last week, cover duplications in which the same – or some of the same – authors published the same – or some of the same – information in two different papers.

Most duplications are straightforward — all authors simply send the same or similar study to two or more journals, a violation of most journals’ terms of use.  For instance: Continue reading You’ve been dupe’d: Data so nice, you see them twice

Authorship dispute fells membrane paper

A membrane paper has been retracted only two months after publication in the Journal of Physical Chemistry B because of an authorship dispute.

The paper, “Magnetic Interaction of Transition Ion Salts with Spin Labeled Lipid Membranes: Interplay of Anion-Specific Adsorption, Electrostatics, and Membrane Fluidity,” has not been cited, according to Thomson Scientific’s Web of Knowledge. (It appears to be taken down entirely, but it looks like you can read its abstract here.)

Here’s the entire — very short — note:

Paper on the adhesiveness of a material doesn’t stick

1-s2.0-S0169433215X00213-cov150hApplied Surface Science has retracted an article that looks at the structure of thin tungsten-titanium coating, because it was submitted without all of the co-authors’ consent.

According to the introduction of the paper, “Structure adhesion and corrosion resistance study of tungsten bisulfide doped with titanium deposited by DC magnetron co-sputtering,” such thin films are “widely used as a surface treatment for optimizing base material properties.”

Here’s the retraction note in full, published in the September issue of the journal:

Wound healing paper injured beyond repair

Errors in the interpretation of some of the data — the result of “procedural flaws” —  are to blame for the retraction of a paper on a way to help skin grow back after injury.

The paper explores a method involving nanofibers. According to the abstract:

In this study, tilapia skin collagen sponge and electrospun nanofibers were developed for wound dressing…the collagen nanofibers stimulated the skin regeneration rapidly and effectively in vivo.

The paper was published January 19, 2015 by ACS Applied Materials and Interfaces, then retracted eight months later, in August. It has not been cited, according to Thomson Scientific’s Web of Knowledge.

Here’s the retraction note:

Can a journal retract its plan to retract? Science may

351-6270-cover

Science is reconsidering its plan to retract a paper about using RNA to make palladium nanoparticles after one of the authors submitted a last-minute correction.

Editor in chief Marcia McNutt told us that the journal will make a decision about whether to retract or correct the paper by February 5th.

We are not certain that what he submitted changes anything, but we wanted to consider this new information before acting.

In the meantime, today the journal issued an Expression of Concern for the paper.

The journal’s initial decision to retract the paper stemmed from an investigation at the National Science Foundation, which concluded that co-authors Bruce Eaton and Dan Feldheim — currently at the University of Colorado at Boulder — engaged in “a significant departure from standard research practices,” and cut them off from NSF funding unless they took specific actions. When the report on the investigation came to light earlier this month, Science editor in chief Marcia McNutt told us that she planned to issue a retraction:

We are checking to see how soon we can get it published.

McNutt explained what changed:  Continue reading Can a journal retract its plan to retract? Science may

Former UCSD prof’s company admits to grant fraud

court caseA company headed by a former astrophysicist at the University of California, San Diego, has agreed to forfeit $180,000 after admitting to defrauding the government.

If SciberQuest, Inc. is unable to pay back the money — the result of fraudulently obtaining government grants and contracts — then its CEO Homayoun Karimabadi will be personally liable, the lawyer for SciberQuest and Karimabadi told Retraction Watch.

We asked if the company was going to be able to repay the $180,000; in response, Robert Rose of firm Sheppard Mullin told us: Continue reading Former UCSD prof’s company admits to grant fraud
