Cell biologist Hanna issues two errata; images mysteriously disappear from Imgur

Cell biologist Jacob Hanna, the highly cited stem cell researcher currently at the Weizmann Institute of Science,  has posted a long erratum for a 2005 paper in Blood for “inadvertent mistakes,” among other issues; soon after, Hanna’s team issued another erratum for a 2009 Cell Stem Cell paper.

There’s more to tell: Last month, commenters on PubPeer noticed that images from at least 10 of the research papers Hanna coauthored in seven journals — that commenters had posted on the image hosting website Imgur and linked to on PubPeer — had been deleted.

Imgur did not confirm whether these specific images had been deleted, but told Retraction Watch:

Second correx for controversial paper on the financial benefits of climate change

Journal of Economic PerspectivesThe Journal of Economic Perspectives has published a second correction for a 2009 paper that argued that some amount of global warming could lead to economic gains.

The author of “The Economic Effects of Climate Change,” Richard Tol, a professor of economics at the University of Sussex, blamed earlier problems with the paper on “gremlins.” In a notice posted last year, Tol wrote that “minus signs were dropped”; he also added a pair of “overlooked estimates” and several recently published studies.

After the first correction was published, several people contacted the JEP to point out more issues with the paper. Editors worked with Tol and outside researchers to update the paper again.

Here’s some text from the newest correction notice:

Duke lung researcher up to seven retractions

Enviromental Health Perspectives

More journals have pulled papers co-authored by researchers Erin Potts-Kant and Michael Foster, at Duke University, bringing the total up to seven for Potts-Kant and six for Foster.

Authors were unable to replicate the experiments after “concerns about the initial data from the animal physiology laboratory” led them to reanalyze source data, according to the note in Environmental Health Perspectives. The comparison showed “potential inconsistencies in the data,” which “significantly impact the overall conclusions of the manuscript.” Similar issues appear to have felled the pair’s other papers, including the other two recent retractions in the American Journal of Respiratory and Critical Care Medicine and the American Journal of Physiology – Lung Cellular and Molecular Physiology — but in the latter case, the discrepancies don’t affect the conclusion.

Potts-Kant was arrested on embezzlement charges in 2013. Authorities alleged that she stole almost $15,000 from Duke University.

Environmental Health Perspectives posted a retraction in July, for a 2012 paper that looked at the molecular underpinnings in airways that react to ozone.

“To our horror”: Widely reported study suggesting divorce is more likely when wives fall ill gets axed

home_coverA widely reported finding that the risk of divorce increases when wives fall ill — but not when men do — is invalid, thanks to a short string of mistaken coding that negates the original conclusions, published in the March issue of the Journal of Health and Social Behavior.

The paper, “In Sickness and in Health? Physical Illness as a Risk Factor for Marital Dissolution in Later Life,” garnered coverage in many news outlets, including The Washington Post, New York magazine’s The Science of Us blog, The Huffington Post, and the UK’s Daily Mail . 

But an error in a single line of the coding that analyzed the data means the conclusions in the paper — and all the news stories about those conclusions — are “more nuanced,” according to first author Amelia Karraker, an assistant professor at Iowa State University.

Karraker — who seems to be handling the case quickly and responsibly —  emailed us how she realized the error:

HIV postdoc faked data in published paper, 2 grants

Julia Bitzegeio

An HIV researcher has admitted to faking data in a published paper, a manuscript, and two grant applications, according to a notice released today by the the Office of Research Integrity (ORI).

Former postdoc Julia Bitzegeio faked data in a 2013 paper, published in the Journal of Virology, about how HIV adapts to interferon. In the paper, “the manipulation was really minor,” Theodora Hatziioannou, principal investigator of the lab at the Aaron Diamond AIDS Research Center (ADARC) in New York City where Bitzegeio worked, told Retraction Watch. “She just made cosmetic changes.”

The paper will be corrected, Hatziioannou said. Bitzegeio has left her lab, and her future is somewhat less clear:

Two retractions cost economic historian book chapter and journal article

markets and morality

Francisco Gómez Camacho has lost an introduction in The Journal of Markets and Morality of a 2005 issue “for improper use of published material without attribution, as well as a a chapter in a collection of 13 scholarly essays  by Brill Publishers due to “serious citation issues.”

The introduction — to a translation of another scholars’ work, Luis de Molina’s Treatise on Money — is no longer in the online version of The Journal of Markets and Morality. On the cover page, and in the table of contents, of the treatise, references to the introduction are crossed out. Where it once was in the text — page 5 of the PDF of the treatise — is a short retraction notice:

Gynecologic cancer researcher up to 13 retractions

13277Noriyuki Takai, a gynecologic cancer researcher at Oita University in Japan, has lost another five papers. With a new total of 13, that means he’s now on our leaderboard.

Three of the retractions are from the journal Tumor Biology, one is from the International Journal of Gynecological Cancer, and one from Anticancer Research.

Takai is the first author on all 5 papers.

As has been the case with Takai’s retractions, and there’s evidence that all were felled by issues with figures. In all, according to the retraction notices, “original data were processed inappropriately.” Four end with the following sentence (or some close variation thereof):

Gut paper retracted after university review says “figures cannot be validated by original data”

IBDA biologist at Case Western Reserve University School of Medicine in Ohio has retracted a paper from Inflammatory Bowel Diseases after a university review found the figures within it could not be “validated by original data.”

The 2010 paper, “Elevated IL-13Rα2 in intestinal epithelial cells from ulcerative colitis or colorectal cancer initiates MAPK pathway,” concerns the elevated expression and role of an inflammatory protein in colon cancer cells.

According to the notice, corresponding author and biologist Alan Levine — who recently received a $3.9 million Avant-Garde Award for HIV/AIDS Research from the National Institute on Drug Abuse — requested the retraction.

Paper cited by New York Times for key stat gets retracted

the-new-york-times-logoA paper that had served as the key aspect of an April New York Times article about a recent surge of violence against immigrants in South Africa has since been retracted for plagiarism.

The research, which appeared in the Mediterranean Journal of Social Sciences, had served as the source of the newspaper’s statement that the country is “home to about five million immigrants.” That figure was later quoted in other media outlets about the issue.

However, a 2011 census put the number closer to 2.2 million immigrants, according to the non-profit fact-checking organization Africa Check. After issuing a report about the discrepancy, which also quotes experts who say the numbers are unlikely to have doubled by 2015, Africa Check contacted the Times. As Africa Check reports:

Hundreds sign letter criticizing Science for reinforcing “damaging stereotypes”

scienceAfter an advice columnist for Science Careers suggested a postdoc “put up with” an adviser’s wandering gaze in June, and an author of a piece in Science partly credited his success to his wife (a Ph.D. scientist) who assumed “the bulk of the domestic responsibilities” in July, some readers have gotten fed up.

These examples are two of four recent instances from Science that reinforce “damaging stereotypes about underrepresented groups in STEM fields,” according to a letter penned by scientists Aradhna K. Tripati, Jennifer B. Glass and Lenny Teytelman. As of this morning, the letter has been signed by more than 300 people; it will be sent to Science/AAAS Editors on Tuesday, July 21.

We showed the letter to Marcia McNutt, the Editor in Chief of Science — set to become the first female leader of the 152-year-old National Academy of Sciences — and she told us:
