Korean stem cell investigation expands to another researcher, and more papers

Last month, we brought you the story of Soo-Kyung Kang, a Seoul National University stem cell researcher who has now retracted four papers amidst questions about image manipulation in a total of 14 studies. That story has drawn a great deal of attention in Korea, with comparisons to the Woo-Suk Hwang scandal, and has even led to a profile of Retraction Watch in the Seoul Daily, one of Korea’s largest newspapers.

We’ve now learned that the investigation has grown to 25 papers after an anonymous whistleblower warned about possible data fabrications in another paper by Kang, an associate professor of veterinary biotechnology, and Kyung-Sun Kang, director of the Adult Stem Cell Research Center in the same department (but no relation). And Soo-Kyung Kang was investigated in 2010, according to the Korea Herald.

The researchers’ labs are also under lockdown Continue reading Korean stem cell investigation expands to another researcher, and more papers

FASEB J retracts 15-year-old study after author comes forward, but universities decline to investigate

The FASEB Journal — FASEB stands for the Federation of American Societies for Experimental Biology — is retracting a 15-year-old paper without the consent of all of the authors, despite what seem like valiant attempts to figure out exactly what went wrong.

Here’s the notice for the University of Bern-University of Urbino paper:

Former Millennium Villages Project staffer responds to critical Nature editorial

Last week, we wrote about a correction of a heavily criticized paper in The Lancet by the Millennium Villages Project, a large aid program. Paul Pronyk, director of monitoring and evaluation at Columbia University’s Center for Global Health and Economic Development, which runs the Project, left his job shortly after writing an explanatory letter that accompanied the correction.

That correction had come after a letter to The Lancet, but also after Nature had raised issues in an editorial. Nature’s editorial concluded: Continue reading Former Millennium Villages Project staffer responds to critical Nature editorial

Computational chem journal retracts article for, um, computation error

If you’re going to publish in the Journal of Computational Chemistry, it probably makes sense to have one’s computer tuned up for the task.

Or else you might wind up like a group of researchers in China who had to endure this misfortune: Continue reading Computational chem journal retracts article for, um, computation error

Lead author of major breast cancer study announced at ASCO co-authored two corrected papers with Anil Potti

One of the biggest stories so far out of the American Society of Clinical Oncology (ASCO) meeting that just ended in Chicago was that of T-DM1, which, according to Ivan’s Reuters colleagues, “extended the length of time breast cancer patients lived without their disease getting worse.” (The news was even the subject of an embargo break.)

The widely-hailed study of Roche’s drug was led by Duke’s Kimberly Blackwell, who told The New York Times: Continue reading Lead author of major breast cancer study announced at ASCO co-authored two corrected papers with Anil Potti

Retraction count for resveratrol researcher Dipak Das rises to 12

Das, via UConn

Dipak Das, the UConn researcher whom the university earlier ths year found to have fabricated or falsified data more than 100 times, has four more retractions to his name.

The notices appear in the June 1, 2012 issue of the American Journal of Physiology: Heart and Circulatory Physiology, and suggest that Das was not all that cooperative: Continue reading Retraction count for resveratrol researcher Dipak Das rises to 12

Psychologists take a gamble on using data about risky behavior, and are forced to retract a paper

When the first sentence of a science paper reads like this, you might think you’re in for quite a ride:

Jumping out of an airplane may seem like a crazy and scary thing to do, but for a skydiver it is a fun and exciting experience.

Unfortunately for the authors of an earlier version of that paper comparing gamblers and skydivers, published in 2011 in the Scandinavian Journal of Psychology, the ride was short-lived, according to a retraction notice just published: Continue reading Psychologists take a gamble on using data about risky behavior, and are forced to retract a paper

‘Molecular characterization’ errors lead to retraction from medicinal chemistry journal

The European Journal of Medicinal Chemistry has published a curious retraction notice for a paper in its February 2012 issue from a group of Indian scientists.

The abstract of the article,”Proton-pumping-ATPase-targeted antifungal activity of cinnamaldehyde based sulfonyl tetrazoles,” is still available on Medline:

Here’s what the abstract of the paper said about the study: Continue reading ‘Molecular characterization’ errors lead to retraction from medicinal chemistry journal

Millennium Villages Project forced to correct Lancet paper on foreign aid as leader leaves team

A senior member of a high-profile foreign aid research team has left the project on the heels of a Lancet correction of a heavily criticized paper the team published earlier this month.

Paul Pronyk, who until last week was director of monitoring and evaluation at Columbia University’s Center for Global Health and Economic Development, which runs the Millennium Villages Project, wrote a letter to the Lancet acknowledging errors in the paper, “The effect of an integrated multisector model for achieving the Millennium Development Goals and improving child survival in rural sub-Saharan Africa: a non-randomised controlled assessment,” originally published May 8. That admission came after Jesse Bump, Michael Clemens, Gabriel Demombynes, and Lawrence Haddad wrote a letter criticizing the work, which was published this week accompanied by corrections to the paper: Continue reading Millennium Villages Project forced to correct Lancet paper on foreign aid as leader leaves team

An Immunity retraction for Luk van Parijs, three years after the ORI found evidence of fabrication in the paper

Earlier this month, we reported on a correction by Luk van Parijs, the biologist the Massachusetts Institute of Technology (MIT) fired in 2005 after he admitted to making up data.

Immunity has now run a retraction involving van Parijs, dated May 25, 2012, for 2003’s “Autoimmunity as the Consequence of a Spontaneous Mutation in Rasgrp1”: Continue reading An Immunity retraction for Luk van Parijs, three years after the ORI found evidence of fabrication in the paper
