Carlo Croce, Ohio State researcher facing misconduct allegations, suing New York Times for defamation

with 20 comments

Carlo Croce

Carlo Croce, a cancer researcher at The Ohio State University who has faced numerous allegations of research misconduct, has filed a lawsuit against the New York Times, claiming the newspaper defamed him in a March 8 story.

Croce filed the civil suit May 10, in the US District Court for the Southern District of Ohio, naming as co-defendants Times reporters James Glanz and Agustin Armendariz, publisher Arthur Sulzberger, Jr., and executive editor Dean Baquet. According to court documents, he’s seeking damages in excess of $75,000. The Times lawsuit was first reported by Courthouse News in May, but it’s actually the second defamation suit Croce filed that we know of.

In April, we’ve recently learned, Croce filed a separate defamation lawsuit against David Sanders, a professor at Purdue University and a key source for the Times story. Croce is seeking damages from Sanders in excess of $75,000.

Croce’s lawyer, Thomas Hill, of Columbus, Ohio firm Kegler Brown Hill + Ritter, told Retraction Watch his client was fighting a “David and Goliath battle” against the Times: Read the rest of this entry »

Carlo Croce, OSU cancer researcher under investigation, retracts paper

with 5 comments

Carlo Croce

A researcher whose work has come under repeated scrutiny has retracted a 2008 paper for “errors that occurred in the construction” of various figures.

Carlo Croce, the corresponding author of the newly retracted paper, has been dogged by misconduct accusations for years — as recently described in the New York Times. His employer, The Ohio State University, has recently re-opened an investigation into his work. Seven of his papers have now been retracted, and fourteen have been corrected for image and text issues such as manipulation, duplication, and errors, as well as two others earning expressions of concern.

Here’s the retraction notice for “Fhit Interaction with Ferredoxin Reductase Triggers Generation of Reactive Oxygen Species and Apoptosis of Cancer Cells,” in the Journal of Biological Chemistry: Read the rest of this entry »

OSU researcher under investigation corrects paper cited 500 times

with 2 comments

An EMBO journal has issued a correction for a well-cited 2012 review co-authored by a cancer researcher under investigation.

Carlo Croce, the last author on the review, has been beleaguered by misconduct accusations that have followed him for years (recently described in a lengthy article in the New York Times), and his university has recently re-opened an investigation into his work.

By our count, Croce — based at The Ohio State University — has logged six retractions, along with multiple expressions of concerns and corrections. The latest correction, in EMBO Molecular Medicine, notes the review lifted passages from multiple publications — and was in turn reused in later papers, as well.

Here’s the notice:

Journals retract paper, flag two others by cancer doc under investigation

with 12 comments

Carlo Croce

This weekend, Carlo Croce had some reprieve from the misconduct accusations that have followed him for years (recently described in a lengthy article in the New York Times) and that have prompted his university to re-open an investigation. On Sunday, he received a prestigious award from the American Association for Cancer Research, honoring his work.

But the moment may have been short-lived. Today, Croce received two expressions of concern (EOCs) from PNAS for two well-cited papers published over a decade ago, on which Croce — chair of the Department of Cancer Biology and Genetics at The Ohio State University (OSU) — is last author. The two EOCs cite concerns over duplicated bands. What’s more, another journal recently decided to retract one of his papers, citing figures that didn’t represent the results of the experiments.

PNAS chose to issue EOCs, rather than retractions or corrections, because the authors didn’t agree that the bands were duplicated, according to executive editor Diane Sullenberger. She explained how the journal learned of the issues with the two papers: Read the rest of this entry »

Cancer org bestows award on scientist under investigation

Carlo Croce

This month hasn’t been all bad for Carlo Croce. Despite issuing two corrections and being the subject of a lengthy New York Times article about how he’s dodged misconduct accusations for years (prompting his institution to re-open an investigation), Croce is now the recipient of a prestigious award from the American Association for Cancer Research.

In a recent news release, the AACR announced it was bestowing Croce the 11th Margaret Foti Award for Leadership and Extraordinary Achievements in Cancer Research, named after the CEO of the AACR, for his work in the field.

According to the news release:

Group whose findings support video game-violence link loses another paper

with 3 comments

Last July, Joseph Hilgard, a postdoctoral fellow at the Annenberg Public Policy Center at the University of Pennsylvania, saw an article in Gifted Child Quarterly that made him do a double take. Hilgard, who is studying the effects of violent media on aggressive behavior, said the results of the 2016 paper “caused me some alarm.”

The research—led by corresponding author Brad J. Bushman, a professor of communication and psychology at The Ohio State University (OSU)—showed that gifted and non-gifted children’s verbal skills dropped substantially after watching 12 minutes of a violent cartoon. The violent program had a greater impact on the gifted children, temporarily eliminating the pre-video verbal edge they displayed over their non-gifted peers.

To Hilgard, the results suggested that violent media can actually impair learning and performance. But the effect size was huge — so big, Hilgard thought it had to be a mistake. This, plus other questions, prompted Hilgard to contact the authors and the journal. Unfortunately, once he got a look at the data — collected by a co-author in Turkey who became unreachable after the recent coup attempt — the questions didn’t go away. So the journal decided to retract the paper.

Bushman’s body of work has continually supported the idea that violent media increases aggressive behavior, including a controversial 2012 study “Boom, Headshot!” that was retracted earlier this year.

What first struck Hilgard as odd about the 2016 paper was how large the effect of the violent cartoon was: Read the rest of this entry »

Another correction for prominent cancer researcher who’s dodged accusations for decades

with one comment

The chair of a biology department who has faced years of misconduct accusations has taken another hit—a lengthy correction due to text “overlap” between one of his PNAS papers and six other articles.

According to the correction, a reader contacted the journal to notify the editors that text and sentences in multiple sections of the 2015 paper — on which Carlo Croce is last author — were lifted from other sources without quotation marks.

This is the second correction for Croce in PNAS regarding overlap issues in just the last few weeks—the first was published on March 7 (see here). In both instances, PNAS did not call the textual similarities plagiarism, but the notice details multiple instances of overlap.

Croce, the chair of the department of cancer biology and genetics at The Ohio State University (OSU), is no stranger to controversy.

Cancer researcher has dodged accusations for decades (and has a new correction)

with 35 comments

Today isn’t a great day for Carlo Croce, chair of the department of cancer biology and genetics at The Ohio State University (OSU).

The New York Times has a lengthy article detailing the misconduct accusations that have swirled around Croce for years. We’ve covered many, but The Gray Lady obtained documents that show there have been many more.

The story mentions a 2013 letter from Ohio State University to pseudonymous whistleblower Clare Francis (which we reported on in 2014), acknowledging Francis’s allegations against Croce. However, in the letter, an administrator said OSU saw no reason to investigate Croce.

The story didn’t stop there, as the Times reports:
