Image correction in Current Biology for Harvard’s Sam Lee

The work of Sam W. Lee, a cancer biologist at Harvard and Massachusetts General Hospital, has come under fire at Science Fraud lately over concerns about the possible reuse of images in his group’s published studies.

Turns out there’s some there, there after all. The journal Current Biology has issued a pretty thorny correction for one of Lee’s 2006 articles, “RhoE Is a Pro-Survival p53 Target Gene that Inhibits ROCK I-Mediated Apoptosis in Response to Genotoxic Stress,” citing multiple issues with its figures: Continue reading Image correction in Current Biology for Harvard’s Sam Lee

The Nature paper that required three corrections

In baseball, it’s three strikes and you’re out. In Nature, apparently, you can stay at the plate after three swings-and-misses.

That’s what we concluded from a Corrigendum in last week’s issue, for “CD95 promotes tumour growth,” originally published in May 2010 and now corrected not once, not twice, but three times.

Here was the first Corrigendum, from March 2011: Continue reading The Nature paper that required three corrections

ORI investigating University of Florida ob-gyn researcher accused of misconduct

A prominent researcher at the University of Florida is under federal investigation for research misconduct and has lost at least one paper as a result of the fraud.

The researcher, Nasser Chegini, was a professor of obstetrics and gynecology at the U of Florida until about six months ago, when he retired, according to the chair’s office. Nasser has received at least $4 million in federal grant funding, according to the university.

The retracted paper, “MicroRNA 21: response to hormonal therapies and regulatory function in leiomyoma, transformed leiomyoma and leiomyosarcoma cells,” was published in 2010 by Molecular Human Reproduction. The authors were Qun Pan and Xiaoping Luo and Chegini.

As the notice explains: Continue reading ORI investigating University of Florida ob-gyn researcher accused of misconduct

Correction for MD Anderson’s Bharat Aggarwal arches eyebrows for the right reasons

We’ve written about mega-corrections that allow scientists to retrace virtually all of their steps yet preserve their publications as supposedly legitimate. And we’ve seen plenty of corrections that allow authors to assert that their conclusions are correct when evidently important pieces of data are themselves unreliable.

Now comes a correction that seems to us to strike the right chords, given the fact that editors are to a large extent at the mercy of authors in these situations. Continue reading Correction for MD Anderson’s Bharat Aggarwal arches eyebrows for the right reasons

Three gynecologic cancer studies retracted for figure duplication, image manipulation

Journal retracts nanoparticle paper, citing widespread misuse of sources

The  International Journal of Nanomedicine is retracting a paper it published in June that appears to contain an impressive amount of misappropriated text and figures.

The article, “Particokinetics: computational analysis of the superparamagnetic iron oxide nanoparticles deposition process,” came from a group at the Hospital Israelita Albert Einstein, in São Paulo, Brazil, led by Walter Cárdenas. According to the notice: Continue reading Journal retracts nanoparticle paper, citing widespread misuse of sources

Immunology paper retracted because “documents were not archived with due diligence”

University clears leading dermatology lab head of misconduct as authors issue two corrections

Michael Hertl, a leading dermatology researcher at Philipps-University Marburg, has been cleared of any wrongdoing in a case that spawned a retraction last year and two just-published retractions.

Felicitas Riedel, a legal officer for the university, tells Retraction Watch that the

…Committee for Scientific Misconduct of the Philipps-University Marburg closed the matter and submitted its results to the President of the University who in the meantime after examination consented with it.

The findings? Continue reading University clears leading dermatology lab head of misconduct as authors issue two corrections
