A Korean stem cell journal has retracted a paper on a controversial Italian treatment that involves harvesting stem cells from bone marrow and injecting them back into the patient. “Stamina therapy” has been pitched as a treatment for everything from Parkinson’s disease to coma, based on a U.S. patent application filed in 2010. The Italian … Continue reading Paper on controversial stem cell “stamina therapy” retracted
A one-time media favorite is being accused of serious misconduct in three cases where he inserted artificial windpipes into patients and treated them with stem cells. Two of the patients have died; one survives, but needs her airway cleaned every four hours by hospital staff to keep her alive. A little over two years ago, thoracic … Continue reading “Super-surgeon” who created artificial tracheas facing new misconduct allegations
Harvard stem cell researcher Doug Melton got a lot of press last year for research on a hormone he named betatrophin, after its supposed ability to increase production of beta cells, which regulate insulin. Now, the conclusions from that paper, which has been cited 59 times, according to Thomson Scientific’s Web of Knowledge, have been called … Continue reading “I kind of like that about science:” Harvard diabetes breakthrough muddied by two new papers
Here’s another installment of PubPeer Selections:
Nature, as we and others have noticed, has had what Paul Knoepfler referred to as a “torrent” of retractions in the past two years. That torrent — 13 research papers — has prompted a welcome and soul-searching editorial, as it did in 2010 when the journal had what it called an “unusually large number” of … Continue reading Nature, facing “considerable rise” in retractions, blames lawyers for opaque and delayed notices
Last month, PubPeer announced that a scientist had threatened to sue the site for defamation. At the time, all PubPeer would say was that the “prospective plaintiff” is a US researcher” who was “aggrieved at the treatment his papers are getting on our site.” Today, PubPeer revealed the that the prospective plaintiff was Fazlul Sarkar, … Continue reading Scientist threatening to sue PubPeer claims he lost a job offer because of comments
The week at Retraction Watch featured revelations about the backstory of an expression of concern, and Office of Research Integrity findings in a case that had its beginnings in Retraction Watch comments. Here’s what was happening elsewhere:
A day after we published the cover letter and peer review reports about the STAP stem cell paper rejected by Science, Science‘s news section has published the same material for the version rejected by Nature. From Science‘s news story about the document:
Retraction Watch readers are of course familiar with the STAP stem cell saga, which was punctuated by tragedy last month when one of the authors of the two now-retracted papers in Nature committed suicide. In June, Science‘s news section reported: Sources in the scientific community confirm that early versions of the STAP work were rejected … Continue reading “Truly extraordinary,” “simply not credible,” “suspiciously sharp:” A STAP stem cell peer review report revealed
As Retraction Watch readers probably know, we’re big fans of PubPeer, the post-publication peer review site that allows comments on papers. Discussions there have led to a number of corrections and retractions, and even more importantly, authors are starting to respond to clarify results, acknowledge errors, or otherwise advance knowledge. After all, as we often … Continue reading PubPeer Selections: Boosting memory in Science, extending lifespan in Nature, quantum anesthesia in PNAS
