Joachim Boldt retraction tally drops by one, editors say (but record’s still safe)

As the news of Joachim Boldt’s staggering number of retractions leaps from Retraction Watch into the mainstream press, the consortium of journal editors retracting his studies has backtracked ever so slightly, announcing today that one of the 89 studies for which the German anesthesiologist lacked ethics approval in fact had such sanction.

According to the now-16 (Updated 3/7/11, as it is up from 11 several days ago) editors, LÄK-RLP,  the German body investigating the ethics component of the Boldt case: Continue reading Joachim Boldt retraction tally drops by one, editors say (but record’s still safe)

Plagiarism and other ‘negligence’ fell lung-estrogen paper

There’s parsing a-plenty in the American Journal of Physiology Lung Cellular and Molecular Physiology this month. The journal has retracted a 2010 paper by researchers at Chiba University in Japan, who lifted much of their manuscript from an article by other scientists in a different publication.

The authors of the paper, “The estrogen paradox in pulmonary arterial hypertension,” confess that they misappropriated text. But how they do so is a case study in subtlety: Continue reading Plagiarism and other ‘negligence’ fell lung-estrogen paper

Ladies and gentlemen, we have an apparent retraction record holder: Joachim Boldt, at 89

It’s official.* Joachim Boldt now holds the record for the most retractions by a single author.

As we reported the other day, a group of anesthesia journals was on the verge of revealing a list of 89 articles by Joachim Boldt that would require retraction because the German researcher had failed to receive proper approval from ethics officials for his studies. Today, the coalition issued a letter making the retractions official.

The 89 papers join an earlier retraction in October.

Of note: Continue reading Ladies and gentlemen, we have an apparent retraction record holder: Joachim Boldt, at 89

NEJM retracts Potti paper

About a month ago, the New England Journal of Medicine told us that they didn’t “have any plans” to retract a paper by Anil Potti. Apparently, they’ve changed their minds.

Today, they posted this retraction notice: Continue reading NEJM retracts Potti paper

A Nature chain retraction for Arabidopsis paper, and some unanswered questions

courtesy Nature

If a paper is retracted, should papers that cite it get retracted, too? We’ve been on the lookout for this kind of move, which we figure is consistent with cleaning up the scientific record. Today, one appears in Nature.

The original paper, “Mediation of pathogen resistance by exudation of antimicrobials from roots,” purported to show how a particular bug evades the immune system of Arabidopsis, a plant commonly used in the lab. It has been cited 51 times, according to Thomson Scientific’s Web of Knowledge.

The retraction notice says that the paper’s conclusions could no longer be supported because one of the key references — a paper in the Journal of Agricultural and Food Chemistry by many of the same authors — had been retracted: Continue reading A Nature chain retraction for Arabidopsis paper, and some unanswered questions

Two more retractions for Mori make 16 — but not a record

Biochemical Journal has retracted two articles by Naoki Mori, bringing the total number of pulled papers by the Japanese cancer researcher to sixteen.

As with the previous Mori retractions, the latest ones — of papers published in 2007 and 2010 — involve unreliable images. Mori, you’ll recall, had recycled control blots from study to study over the years, and was dismissed from his academic post in August.

The 2007 paper, “Activation of hypoxia-inducible factor 1 in human T-cell leukaemia virus type 1-infected cell lines and primary adult T-cell leukaemia cells,” also included a frequent co-author Mariko Tomita, who has been implicated in the deception. It has been cited 15 times, according to Thomson Scientific’s Web of Knowledge. The 2010 article, “Inhibition of Akt/GSK3β signalling pathway by Legionella pneumophila is involved in induction of T-cell apoptosis,” has not yet been cited.

In each case, the retraction notice is the same: Continue reading Two more retractions for Mori make 16 — but not a record

German defense minister Guttenberg resigns after losing his PhD for a plagiarized thesis

Karl-Theodor zu Guttenberg, who was stripped of his PhD last week after being found guilty of plagiarizing his law thesis, has resigned his post as Germany’s defense minister. According to Reuters:

“I was always ready to fight but I’ve reached the limit of my powers,” Guttenberg, 39, told journalists in a hastily arranged news briefing at the Defense Ministry in Berlin.

“I informed the chancellor in a very friendly conversation that I’m resigning from political offices and requested to be relieved. It’s the most painful step of my life.”

As we wrote last week, a Bremen University professor first discovered the plagiarism, which was then explored a wiki. The University of Bayreuth took away his doctorate on Wednesday the 23rd.

22 papers by Joachim Boldt retracted, and 67 likely on the way

Self-plagiarism alert: A very similar version of this post is being published online in Anesthesiology News, where one of us (AM) is managing editor.

Anesthesia & Analgesia has retracted 22 papers by Joachim Boldt, the discredited German anesthesiologist whose prolific career as a researcher has unraveled with stunning rapidity — and 67 more retractions are likely on the way from 10 other titles  that have published his work.

The 22 retractions, announced Feb. 25 on the journal’s website, come less than a month after the state medical board overseeing an investigation into Boldt’s publications said that it was looking into more than 90 of his articles out of concern that he had failed to obtain proper approval from an institutional review board for the work.

The board, Landesärztekammer Rheinland-Pfalz (LÄK-RLP), investigated 102 articles. Investigators could not find evidence of adequate IRB approval for 89 papers; for the remaining, 11 had IRB approval and two did not require it, according to the A&A notice, which was signed by  editor-in-chief Steven L. Shafer: Continue reading 22 papers by Joachim Boldt retracted, and 67 likely on the way

Crystal myth: 11 more retractions from crystallography journal after 2010 fakery

About a year ago, Acta Crystallographica Section E issued a bombshell editorial. The journal was pulling 70 papers from two groups of researchers at the same Chinese university after discovering that the structures they reported had been fakes.

As the editorial explained, the fraud was detected during a routine review of the structures by Ton Spek, of Utrecht University in The Netherlands. According to the editorial: Continue reading Crystal myth: 11 more retractions from crystallography journal after 2010 fakery

University of Sao Paulo fires professor after a retraction for plagiarism

February has turned out to be a bad month for people found guilty of plagiarism. On Friday, we covered the case of the German foreign defense minister who lost his PhD after his university became aware he had copied passages from newspaper stories into his thesis.

And now we’ve learned that the University of Sao Paolo Paulo (USP) dismissed a full professor earlier this month after an investigation into a study he retracted last year because parts of it had been plagiarized. It has also stripped one of the professor’s former students of her PhD. Continue reading University of Sao Paulo fires professor after a retraction for plagiarism
