A bullshit excuse? My lab notebook “was blown into a manure pit”

CleanA researcher who studies how to turn dairy cattle manure into natural gas falsified and fabricated data in a journal article and failed to declare a commercial conflict of interest, a Washington State University investigation has found.

The study “Evaluation of Co-Digestion at a Commercial Dairy Anaerobic Digester” was published in 2011 in the journal CLEAN: Soil, Air, Water. First author Craig Frear was a Ph.D. student at WSU Pullman when the study was carried out and an assistant professor at the time of the investigation. The editor-in-chief of CLEAN, Prisca Henheik, told us that the retraction is a done deal even though it has not been posted online: Continue reading A bullshit excuse?

Singapore investigation leads to two retractions, two more on the way

cov150hAuthors have retracted papers from Cell Metabolism and the Journal of Biological Chemistry after an investigation in Singapore found issues, including falsified data. The investigation is ongoing, and two additional retractions, along with two corrections, are on the horizon.

The investigation looked into papers by first authors Sudarsanareddy Lokireddy, now a postdoc at Harvard, and Sandhya Sriram, a postdoc at the Agency for Science, Technology and Research in Singapore. Led by the Nanyang Technological University in Singapore, where some of the work was done, the investigation concluded that there were issues with six papers on which either Sriram or Lokireddy was first author.

All authors but Lokireddy have agreed to retractions or corrections. Ravi Kambadur of NTU, and Mridula Sharma at the National University of Singapore, are the last two authors on all the papers.

According to a notice from the NTU, the “investigation found a number of instances of alterations to data” in three papers on which Lokireddy is first author. One of those was retracted December 1 by Cell Metabolism: Continue reading Singapore investigation leads to two retractions, two more on the way

Authors lied about ethics approval for study on obesity, depression

cover (1)

Obesity has retracted a study that suggested overweight people may be less depressed than their slimmer counterparts in cultures where fat isn’t stigmatized, after realizing the authors lied about having ethical approval to conduct the research.

The authors claimed their research protocol had been approved by Norwegian and Bangladeshi ethical committees, but, according to the retraction note, part of the study “was conducted without the required approval of the university ethics board.” The journal’s managing editor told us that there is no evidence that there was harm to the study subjects.

Here’s more from the retraction note for “In Bangladesh, overweight individuals have fewer symptoms of depression than nonoverweight individuals:”

Cancer researcher contributed “false data” to 11 studies

ori-logoA former cancer researcher has falsified data in 11 studies, according to the results of a investigation scheduled to be published in the Federal Register tomorrow.

The Office of Research Integrity’s findings are based on an inquiry at Virginia Commonwealth University, where Girija Dasmahapatra worked until July of this year, investigating possible therapies for cancer. The misconduct affected research funded by three grants from the National Institutes of Health. Steven Grant, a researcher at VCU, is the principal investigator on the grants, each of which total over $2 million in funding. All of the 11 affected papers will be corrected or retracted, according to the ORI notice.

Two of the papers containing “falsified and/or fabricated” data — a study on an experimental combination of drugs for blood cancer and one on chemotherapies for rare forms of lymphoma  — were covered in press releases by VCU.

According to the notice in the Federal Register:

Diederik Stapel now has 58 retractions

stapel_npcSocial psychologist Diederik Stapel has notched his 58th retraction, after admitting he fabricated data in yet another article.

He’s holding onto his 4th place spot on our leaderboard.

This latest retraction is for “Correction or comparison? The effects of prime awareness on social judgments,” published in the European Journal of Social Psychology. As usual for Stapel, this paper has been retracted because he fabricated data.

Voinnet retracts highly cited paper, bringing his total to 7

coverOlivier Voinnet, a well-known plant scientist at the ETH in Zurich, has notched his 7th retraction for a highly cited paper. The 2003 paper was pulled when “additional image manipulations” came to light after The Plant Journal issued a correction earlier this year.

The retraction follows an investigation into — and then retraction of — several other papers co-authored by Voinnet. The authors originally corrected the paper after they learned one image had been duplicated, and repeating the experiment found the “same interpretation and conclusions” held true. But when the corresponding author learned of additional “data manipulation,” they decided to retract the paper altogether.

Here’s the retraction notice for “An enhanced transient expression system in plants based on suppression of gene silencing by the p19 protein of tomato bushy stunt virus:”

MD Anderson researcher Aggarwal up to six corrections

cover (2)A highly cited cancer researcher at MD Anderson has notched three major corrections, all associated with problems in figures. One note cites “human error” as the cause.

Bharat Aggarwal is the last author on all three papers. He is now up to six corrections, two unexplained withdrawals, and two Expressions of Concern. He’s also threatened to sue us in the past, and has told us that his institution has been looking into his work.

Only one note specifies that the correction does not affect the paper’s conclusions.

First up: “Inhibition of growth and survival of human head and neck squamous cell carcinoma cells by curcumin via modulation of nuclear factor-κB signaling,” published in the International Journal of Cancer and cited 168 times, according to Thomson Scientific’s Web of Knowledge. The issues span two figures, according to the erratum note:

How does gender influence publishing? A window into one journal

fec_29_10 100Male and female reviewers may rate papers the same way, regardless of whether the authors are male or female — but women are more likely to get the chance to review papers (and get their own papers reviewed) if other women are involved, according to studies of the review process at Functional Ecology.

In their comprehensive study of manuscripts put through the peer review process at the journal from January 2004 through June 2014, the authors found that the average review scores of manuscripts was roughly the same regardless of whether the reviewer — or editor — was male or female.

The authors also scanned papers submitted to the journal between 2010 and 2014 to look at the impact of gender among authors, and also found papers with female authors receive equivalent scores to papers by men: Continue reading How does gender influence publishing? A window into one journal

“Most responsible course of action is to retract:” Duplicated images fell prostate cancer paper

International Journal of CancerA study on the cellular interactions underlying prostate cancer has been retracted after a whistleblower pointed out duplicated images in one of the paper’s figures that were “erroneously presented as unique.”

The International Journal of Cancer posted the notice in June. The authors backed the paper’s conclusions but agreed, “the most responsible course of action is to retract.”

The notice reads:

More retractions, errata discovered for nursing researcher

Journal of Clinical Nursing

Since our recent coverage about a university investigation that led to multiple retractions for nursing researcher Moon-fai Chan, we’ve been alerted to a few more retractions and errata. His total is now at six retractions and four errata.

Some of our finds were published this year, and some are a few years old. Most are due to duplication; one is due to “use of a dataset without ethical approval.” Chan — now the Associate Master and Chief of Students at the University of Macau — is the first author on all but one of the papers.

We’ll start with the most recent errata. Three of Chan’s articles in the Journal of Clinical Nursing have errata notes published online in July of this year, all noting that the authors used elements of some of Chan’s other articles. Here’s the erratum note for “Exploring risk factors for depression among older men residing in Macau:”
