What do you do after painful retractions? Q&A with Pamela Ronald and Benjamin Schwessinger

2013 was a rough year for biologist Pamela Ronald. After discovering the protein that appears to trigger rice’s immune system to fend off a common bacterial disease – suggesting a new way to engineer disease-resistant crops – she and her team had to retract two papers in 2013 after they were unable to replicate their findings. The culprits: a mislabeled bacterial strain and a highly variable assay. However, the care and transparency she exhibited earned her a “doing the right thing” nod from us at the time.

After many months spent understanding what went wrong and redoing the experiments correctly, today Ronald and her team release another paper in Science Advances that reveals the protein they thought they had identified in 2013.

Ronald and co-first author Benjamin Schwessinger (who recently became an independent research fellow at the Australian National University in Canberra) spoke to us about the experience of recovering from the retractions and finally getting it right. The conversation has been edited for brevity and clarity.

-What did you do differently this time so you didn’t repeat the same mistakes?

“Part of a paper that had already appeared”: Materials paper pulled for plagiarism

1-s2.0-S1387181115X00035-cov150hMicroporous and Mesoporous Materials has retracted a 2015 paper after it was discovered the authors “have plagiarized part of a paper that had already appeared.”

The paper, “Ionic liquid assisted synthesis of flexible and super-hydrophobic porous gels,” described the synthesis of a form of flexible aerogels “through a facile one-pot preparation,” according to the abstract. According to Thomson Scientific’s Web of Knowledge it has been cited zero times.

Here is the retraction note, in full:

Data “mismatch” and author’s illness pluck bird sex-ratio study from literature

coverInaccessible data and an author’s illness are to blame for the retraction of a paper on sex ratios of baby finches, according to the authors.

The paper, “Experimental evidence that maternal corticosterone controls adaptive offspring sex ratios,” published in Functional Ecology, outlined how a hormone in mother finches can “skew” the number of males vs females that hatch from the eggs in her nest.

But after questions about the data were raised, the authors were unable to address the “mismatch” between the experimental data and those that were published. Compounding the situation is the fact that, while working on the paper, first author Sarah Pryke at the Australian National University “was suffering from a medical condition that likely impaired her cognitive abilities,” according to a statement from Pryke’s co-authors.

An email to Pryke was met with an out-of-office reply:

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:

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 Hatziioannouprincipal 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:

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:

“Data fabrication and manipulation have occurred”: Taste bud paper soured by fraud

The Journal of NeuroscienceA 2013 paper on the neurological impact of flavors has been retracted from The Journal of Neuroscience. The retraction notice offers few details (which is typical for the journal), but a statement sent to us by the last author noted that an investigation at the University of Maryland “determined that data fabrication and manipulation have occurred in this study.”

Gustatory Stimuli Representing Different Perceptual Qualities Elicit Distinct Patterns of Neuropeptide Secretion from Taste Buds” examined the relationship between flavors and neuropeptides, molecules that send signals to the brain.

Here’s the retraction notice:
