Stem cell retraction leaves grad student in limbo, reveals tangled web of industry-academic ties

stem cells developmentA contested retraction in Stem Cells and Development has left the Queensland University of Technology (QUT) graduate student who fought for it in limbo, uncertain if he will earn his PhD. And many of those who didn’t want the paper retracted have a significant financial interest in a company whose work was promoted by the research — despite any lack of disclosure in the now-retracted paper.

Here’s the notice: Continue reading Stem cell retraction leaves grad student in limbo, reveals tangled web of industry-academic ties

ORI investigating work from Caltech lab as PNAS paper is retracted

pnas1219The U.S. Office of Research Integrity is investigating work done at a Caltech lab after researchers there couldn’t replicate it, and retracted a paper based on the findings.

Here’s the notice, which ran this week in the Proceedings of the National Academy of Sciences (PNAS): Continue reading ORI investigating work from Caltech lab as PNAS paper is retracted

RNA paper retracted for “carelessness in including some of the figures”

molcellbiochemHere at Retraction Watch, we’ve covered retractions for misconduct, journal errors, editorial system hacking and even no particular reason.

And that’s just in the last week.

However, we’ve identified a new reported reason: carelessness. A paper in Molecular and Cellular Biochemistry claimed to show how a tiny RNA causes fat cells to die.

Instead, the paper died.

Turned out that rather than describe previously published data, the authors say they inadvertently included a figure that had already appeared in another paper.

The retraction for “miR-598 induces replicative senescence in human adipose tissue-derived mesenchymal stem cells via silent information regulator 1,” reads, in full: Continue reading RNA paper retracted for “carelessness in including some of the figures”

Odd: Retractions 18 and 19 for Dipak Das, and a new paper in the same journal, as if nothing were amiss

Dipak Das, the resveratrol researcher found guilty of more than 100 counts of misconduct by the University of Connecticut, has two more retractions for his resume. But that’s not the most interesting part of this post, so keep reading after the notices.

Both retractions appeared in the October 2012 issue of the Journal of Cellular and Molecular Medicine. Here’s the first notice: Continue reading Odd: Retractions 18 and 19 for Dipak Das, and a new paper in the same journal, as if nothing were amiss

Five retractions for cancer research team for manipulated figures

The International Journal of Cancer, a Wiley title, has retracted a pair of articles from a group at UT Southwestern Medical Center in Dallas, for image manipulation.

The papers, from the lab of Adi Gazdar, the W. Ray Wallace Distinguished Chair in Molecular Oncology Research who is known for his massive collection of human cancer cells, were published in 2005.

The first was titled “Aberrant methylation of Reprimo in human malignancies.” According to the retraction notice: Continue reading Five retractions for cancer research team for manipulated figures

Giving thanks for plagiarism detection software: Catching up on retractions for the sincerest form of flattery

Today, on Thanksgiving in the U.S., Retraction Watch is taking a bit of a holiday as we dig into some turkey — not to be confused with retractions from Turkey. We’d like to give thanks for the thousands of Retraction Watch readers all over the world who’ve helped us shine a spotlight on the scientific process, warts and all.

And we imagine that journal editors around the globe are giving thanks to plagiarism detection software such as iThenticate, so today’s post is a roundup of some recent retractions for plagiarism: Continue reading Giving thanks for plagiarism detection software: Catching up on retractions for the sincerest form of flattery

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

Two Moriguchi stem cell papers being retracted

It was, as Nature News wrote last month, a story that “seemed too good to be true:”

Stem-cell transplant claims debunked

Transplant of induced pluripotent stem cells to treat heart failure probably never happened

Hisashi Moriguchi, a visiting researcher at the University of Tokyo, had claimed a result that would have put him years ahead of researchers toiling in stem cell research. But the claims were met with a great deal of doubt — to say the least — and the story began to unravel when Harvard, where Moriguchi said he’d done the work, denied it had ever taken place.

And as expected, the retractions have now started. Today, a Nature Publishing Group journal said they would be retracting two papers, “A therapeutic method for the direct reprogramming of human liver cancer cells with only chemicals” and “Successful cryopreservation of human ovarian cortex tissues using supercooling.” The notices for the Scientific Reports papers will both say the same thing: Continue reading Two Moriguchi stem cell papers being retracted

You’ve been dupe’d: Catching up on authors who liked their work enough to use it again

As we’ve noted before, we generally let duplication retractions make their way to the bottom of our to-do pile, since there’s often less of an interesting story behind them, duplication is hardly the worst of publishing sins, and the notices usually tell the story. (These are often referred to — imprecisely — as “self-plagiarism.”)

But that skews what’s represented here — boy, are there a lot of duplication retractions we haven’t covered! — and we might as well be more comprehensive. Plus, our eagle-eyed readers may find issues that we won’t see on a quick scan.

So with this post, we’re inaugurating a new feature here at Retraction Watch, “You’ve been dupe’d.” Every now and then, we’ll gather five of these duplication retractions at a time, and post them so they get into the mix, and into our category listing (see drop-down menu in right-hand column if you haven’t already). Here are the first five: Continue reading You’ve been dupe’d: Catching up on authors who liked their work enough to use it again
