Nature retracts paper six years after it was flagged for fraud

cover_natureNature retracted a paper on protein structures today, six years after an investigation at the University of Alabama identified several structures that were “more likely than not falsified and/or fabricated” by one of the authors.

The paper came under scrutiny soon after it was published in 2006. A letter published in Nature that same year pointed out “physically implausible features in the structures it described.” That triggered the investigation at the University of Alabama, the result of which was published in 2009, identifying “nine publications related to the same protein structures that should be retracted from various scientific journals.” Everything was pinned on last author H.M. Krishna Murthy, who the investigation determined was “solely responsible for the fraudulent data.”

A 2009 Nature news article on the investigation declared that the “fraud is the largest ever in protein crystallography.”

We’re not sure what took Nature so long to retract the letter, titled “The structure of complement C3b provides insights into complement activation and regulation.” Here’s the note, which explains that not all the authors agreed to the retraction:

Why retraction shouldn’t always be the end of the story

rsc-logoWhen researchers raised concerns about a 2009 Science paper regarding a new way to screen for enzymatic activity, the lead author’s institution launched an investigation. The paper was ultimately retracted in 2010, citing “errors and omissions.”

It would seem from this example that the publishing process worked, and science’s ability to self-correct cleaned up the record. But not so to researchers Ferric Fang and Arturo Casadevall.

Fang, of the University of Washington, Seattle, and Casadevall, of Johns Hopkins — who have made names for themselves by studying retractions — note today in an article for Chemistry World that

Third retraction appears for Leiden researcher fired in 2013

A researcher who was fired from Leiden University Medical Center in 2013 for fraud has notched a third retraction, following an investigation by her former workplace.

When Leiden fired Annemie Schuerwegh, they announced two retractions of papers that contained manipulated data. This third retraction — the last, according to a spokesperson for the center  — is for “a discrepancy between the data reported in the article and the original collected data,” per the note.

The 2011 paper, “Mast cells are the main interleukin 17-positive cells in anticitrullinated protein antibody-positive and -negative rheumatoid arthritis and osteoarthritis synovium” published in Arthritis Research & Therapy, suggests the source of a protein involved in rheumatoid arthritis. It has been cited 51 times, according to Thomson Scientific’s Web of Knowledge.

Here’s the retraction note:

Voinnet’s notice count grows, as he notches his 18th correction

home_coverOlivier Voinnet, a high-profile plant scientist at ETH Zurich, has earned a mega-correction. It wrapped up a rough year for the biologist, which included his seventh retraction, and a CNRS investigation that found evidence of misconduct.

This latest correction, to a paper on the mechanisms behind RNA silencing in Arabidopsis, was published in RNA. The 2007 paper has been cited 101 times, according to Thomson Scientific’s Web of Knowledge. The corrigendum modifies three figures in total.

The notice is long, so we’re not going to post the whole thing here. The first error in “Transitivity in Arabidopsis can be primed, requires the redundant action of the antiviral Dicer-like 4 and Dicer-like 2, and is compromised by viral-encoded suppressor proteins” is a clarification to a legend:

Retraction published for nutrition researcher Marion Nestle

journal_pubhealthFollowing her request last month, a public health journal has retracted a paper co-authored by prominent nutrition researcher Marion Nestle, after revelations of multiple factual errors and her co-author’s ties to one of the subjects of the article.

The article, an opinion piece, critiqued the supposed relationship between the biggest beverage distributor in Guatemala and the leading Guatemala-based public health organization, to distribute a fortified supplement (Manì+) for undernourished children. The relationship, the piece argued, raised concerns about the conflicts of interest that can occur when a food company pairs with a public health organization. But soon after publication, Nestle learned that she and her co-author Joaquin Barnoya had misrepresented that relationship, and failed to disclose that the public health organization was paying a portion of Barnoya’s salary.

Here’s the full retraction notice, published earlier this month by the Journal of Public Health Policy: Continue reading Retraction published for nutrition researcher Marion Nestle

Neuroscience paper retracted after colleagues object to data publication

frontiersA paper published this October in the journal Frontiers In Neuroscience was retracted the following month because the authors’ collaborators did not give them permission to publish some of the data.

The paper detailed how and why the authors use the software program Nengo to test large simulations of nervous system networks. As part of the research, the authors tested five systems, one of which they were working on with another group. Due to a “miscommunication,” the authors thought they had received permission to publish the data; they plan to resubmit a paper describing the other four systems.

Here’s the official retraction note: Continue reading Neuroscience paper retracted after colleagues object to data publication

Stem cell researcher that sued Harvard failed to disclose conflicts on 6 publications

Piero Anversa, a stem cell researcher who we recently learned is leaving Harvard and Brigham & Women’s Hospital after suing them, has added a disclosure statement to six publications.

The four papers and two letters were published in Circulation, and all bear identical corrections:

Piero Anversa, MD, discloses that he is a member of Analogous, LLC.

The author regrets this omission.

Trouble is, we can’t find a company by that name. What we do know:

Author retracts statements about gay conversion therapy

Screen Shot 2015-12-17 at 1.49.17 PM

Key assertions in a paper on homosexuality have been removed from the Journal of the Islamic Medical Association of North America, in what the notice describes as a “partial retraction.”

The 2006 article “Homosexuality: An Islamic Perspective,” states that conversion therapy can be effective, and that gay people have poorer health. Those statements are among those that lack evidence, according to a note on the paper published in July. The retraction pulls those assertions, among others, and instead argues that a homosexual person should be helped to “accept his or her LGB identity,” and find a welcoming community.

The 2006 article is definitely a perspective — it states the opinion of the sole author, M. Basheer Ahmed, who has a private psychiatry practice in Texas, as to whether homosexuality is a choice. He thinks yes, though the science on the matter is fairly clear that it’s not.

But we still think it’s interesting that a journal chose to take back some of the statements contained in the article. Here’s the abstract from the “partial retraction” note:
