Did a NOAA scientist “retract” an overoptimistic oil spill report?

Yesterday, on a story about a Congressional hearing on the progress of oil spill cleanup in the Gulf of Mexico, the Guardian ran the following headline:

BP oil spill: US scientist retracts assurances over success of cleanup

NOAA’s Bill Lehr says three-quarters of the oil that gushed from the Deepwater Horizon rig is still in the Gulf environment while scientists identify 22-mile plume in ocean depths

The story, as do those in the Los Angeles Times, The Hill, and the New Orleans Times-Picayune, among others, point out that Lehr’s testimony seemed at odds with the almost celebratory atmosphere surrounding the release of a National Oceanic and Atmospheric Administration (NOAA) report two weeks ago, “BP Deepwater Horizon Oil Budget: What Happened To the Oil?”

The coverage yesterday also noted that other scientists have criticized the report, and that a study in Science this week suggests there’s still an underwater plume of oil in the Gulf.

But did Lehr actually “retract” assurances over the cleanup’s success, or the report itself? Continue reading Did a NOAA scientist “retract” an overoptimistic oil spill report?

It’s not a tumor: Authors retract 2005 Cancer Research paper linking adult stem cells to cancer

The authors of a 2005 Cancer Research paper that cast some doubt on the safety of a population of adult stem cells used frequently in research have retracted it. According to the retraction, in the August 15 issue of the journal:

Upon review of the data published in this article, the authors have been unable to reproduce some of the reported spontaneous transformation events and suspect the phenomenon is due to a cross-contamination artifact.

Transformation refers to changes in the cells that make them “immortal” — think HeLa cells, made popular by Rebecca Skloot’s book about Henrietta Lacks — and cancer-like. Continue reading It’s not a tumor: Authors retract 2005 Cancer Research paper linking adult stem cells to cancer

American Cancer Society drops ‘Screening is Seeing’ ad campaign

When we started Retraction Watch, Gary Schwitzer suggested that one of us might be a vampire.

Well, Schwitzer, let us say this: You are no Jesus.

However, criticism leveled by Schwitzer at an American Cancer Society (ACS) ad campaign earlier this week has accomplished the Retraction Watch equivalent of turning water into wine. The campaign, he wrote, Continue reading American Cancer Society drops ‘Screening is Seeing’ ad campaign

Shifting gears: Occupational health journal pulls study linking shift work, age and sleep disorders

Blaming “data coding errors,” the Journal of Occupational and Environmental Health has pulled an article linking shift work, age and sleeping problems.

The study was published four months ago, but managed in its brief lifespan to garner significant attention in the mainstream media and the blogosphere, although it has not been cited by any other papers. It comes alongside growing interest in the potential lnks between shift work and various health conditions including irritable bowel syndrome and breast cancer. Denmark even awards damages to shift workers who have developed the latter.

Ironically, the researchers, led by Philip Tucker, of Swansea University in Wales, U.K., had hoped to demonstrate the toll of shift work that previous studies were unable to show conclusively because of “methodological difficulties”: Continue reading Shifting gears: Occupational health journal pulls study linking shift work, age and sleep disorders

The shroud of retraction: Virology Journal withdraws paper about whether Christ cured a woman with flu

It takes decades, and even centuries, to overturn the Catholic canon of law, but medical journals move much more quickly: Just three weeks after the Virology Journal published a paper speculating that a woman described in the Bible as being “cured by our Lord Jesus Christ” had flu, the journal has apologized for ever posting it online.

After bemused — to put it mildly — reactions from bloggers Bob O’Hara (who alerted us to the retraction), P.Z. Myers, and Tara C. Smith, as well as questions from a journal reader, the journal’s editor, Robert F. Garry, posted a retraction to O’Hara’s blog, and in his own journal: Continue reading The shroud of retraction: Virology Journal withdraws paper about whether Christ cured a woman with flu

Monkey business? 2002 Cognition paper retracted as prominent psychologist Marc Hauser takes leave from Harvard

Marc Hauser, a prominent Harvard psychology researcher and author, will be taking a leave of absence from the university following “a lengthy internal investigation found evidence of scientific misconduct in his laboratory” that has led to the retraction of one of his papers, according to The Boston Globe.

The retraction, of a 2002 paper in Cognition, reads, in part: “An internal examination at Harvard University . . . found that the data do not support the reported findings. We therefore are retracting this article,” the Globe reports.  It also includes the sentence “MH accepts responsibility for the error.”

The retraction notice does not yet appear anywhere on the journal’s site, where the PDF version of the study is still available, nor on the Medline abstract. Its circumstances appear to be atypical, according to the Globe: Continue reading Monkey business? 2002 Cognition paper retracted as prominent psychologist Marc Hauser takes leave from Harvard

Department of Redundancy Department: From fish to toxicology, where have all the editors gone?

Readers of three science publications may be wondering, “Where in the world were the editors?” after retractions appeared recently in the journals sounding the same theme: The articles in question had too much “overlap” between previous publications.

For example, the Journal of Fish Biology notice reads, in part: “The retraction has been agreed due to overlap between this article and several previously published articles.”

Translation: Our bad!

The latest retraction notices from the journals Environmental Toxicology, the Journal of Fish Biology and the Journal of Clinical Neurology Continue reading Department of Redundancy Department: From fish to toxicology, where have all the editors gone?

Why write a blog about retractions?

Post by Ivan Oransky and Adam Marcus

The unfolding drama of Anil Potti — a Duke researcher who posed as a Rhodes Scholar and appears to have invented key statistical analyses in a study of how breast cancer responds to chemotherapy — has sent ripples of angst through the cancer community. Potti’s antics prompted editors of The Lancet Oncology to issue an “expression of concern” — a Britishism that might be better expressed as “Holy Shit!” — about the validity of a 2007 paper in their journal by Potti and others.

Unlike newspapers, which strive for celerity as much as accuracy, science journals have the luxury of time. Thorough vetting, through editorial boards, peer reviewers and other filters, is the coin of the realm.

And yet mistakes happen. Sometimes these slips are merely technical, requiring nothing more than an erratum notice calling attention to a backwards figure or an incorrect address for reprints. Less often but far more important are the times when the blunders require that an entire article be pulled. For a glossary of the spectrum between erratum and retraction — including expression of concern — see this piece, commissioned by one of us, Ivan, while he was at The Scientist.

Retractions are born of many mothers. Fraud is the most titillating reason, and mercifully the most rare, but when it happens the results can be devastating. Consider the case of Scott Reuben, a prodigiously dishonest anesthesiologist whose fabrications led to the retraction of more than a score of papers and deeply rattled an entire medical specialty. (One of us, Adam, broke that story.)

So why write a blog on retractions? Continue reading Why write a blog about retractions?
