Fraud, retractions no barrier to US cloning patent for Woo-Suk Hwang

Woo-Suk Hwang is having quite a comeback. The cloning researcher’s fall from grace in 2005 and 2006 was covered worldwide, featuring two high-profile retractions from Science and convictions (now under appeal) on charges he embezzled government funds and broke South Korea’s bioethics law. But as Nature reported last month in a profile focusing on Hwang’s … Continue reading Fraud, retractions no barrier to US cloning patent for Woo-Suk Hwang

A first? Dental journal retracts three papers because authors didn’t pay publication charges

Dental Materials Journal has retracted three papers by different groups of authors for “violation of our publishing policies and procedures” — which turns out to be a polite way of saying “they wouldn’t pay our fees.” The articles are:

Retraction for stem cell scientist facing misconduct inquiry

Here’s a retraction from Stem Cells and Development that we’re just now getting around to covering. The paper, “Non-viral reprogramming of skeletal myoblasts with valproic acid for pluripotency,” appeared in June 2012 in a preliminary online form and was written by a group at the University of Cincinnati. As the retraction notice states:

Stem cell scientist says data in retracted paper “is not falsified or fabricated”

On Wednesday, we brought you the story of a retraction by Gerold Feuer, a State University of New York (SUNY) Upstate Medical Center stem cell scientist whom the university had found to have misused grants. He was suspended, but successfully fought that action. We had asked Feuer for comment at that time, and he has … Continue reading Stem cell scientist says data in retracted paper “is not falsified or fabricated”

Embryonic stem cell paper retracted for fabrication

Stem Cells and Development has retracted a paper it published earlier this year after the leader of the study reported that the data were unreliable. The paper, “Derivation and Genetic Modification of Embryonic Stem Cells from Disease-Model Inbred Rat Strains,” came from the lab of Aron Geurts, of the Medical College of Wisconsin. According to … Continue reading Embryonic stem cell paper retracted for fabrication

Retraction appears for stem cell researcher found to have used funds for his company’s gain

A stem cell journal is retracting a paper by Gerold Feuer, a researcher at the State University of New York (SUNY) Upstate Medical Center in Syracuse who was also found to have misused grants. The Feuer story is complicated. Heralded in 2008 for landing $6.2 million in grants from the New York Stem Cell Board, … Continue reading Retraction appears for stem cell researcher found to have used funds for his company’s gain

Dubious stem cell researcher Moriguchi notches temporary withdrawal, notice of redundant publication

Hisashi Moriguchi, who retracted two papers last year because he and his colleagues could not “guarantee the accuracy of the results and conclusions,” has now had another paper withdrawn — at least temporarily. A notice on the paper, “Autologous human cardiac stem cells transplantation for the treatment of ischaemic cardiomyopathy: first study of human-induced pluripotent … Continue reading Dubious stem cell researcher Moriguchi notches temporary withdrawal, notice of redundant publication

Cell reviewing allegations of image reuse in human embryonic stem cell cloning paper

Cell is looking into whether the authors of a widely hailed study published last week claiming to have turned human skin cells into embryonic stem cells manipulated images inappropriately, Retraction Watch has learned. The potential image problems came to light on PubPeer, a site designed to allow for post-publication peer review. A commenter, identified as … Continue reading Cell reviewing allegations of image reuse in human embryonic stem cell cloning paper

Post 982 — in which we find plagiarized bone graft paper that grafted from other papers

The Surgeon has retracted a 2012 article by a group from the U.K. who took text from a previously published article. So, you say? Nu? Well, we found — through relatively little effort — that the plagiarizees were themselves, shall we say, liberal in their use of material from other sources. The retracted article was … Continue reading Post 982 — in which we find plagiarized bone graft paper that grafted from other papers

Pig cloning paper retracted for being a clone

Once again, the headline has written itself. The journal Animal has retracted a 2010 paper on cloning pig embryos after it became clear that there were “close similarities” between it and a 2009 paper by some of the same authors. Here’s the notice:
