Last month, we broke the news that Emory chemist Craig Hill and colleagues were retracting two papers in the Journal of the American Chemical Society and one in Science. At the time, the Science move was pending, but now the journal has officially pulled the article, titled “A Late-Transition Metal Oxo Complex: K7Na9[O=PtIV(H2O)L2], L = [PW9O34]9–”.
The notice reads: Continue reading Closing loop, Science retracts Hill group oxo paper
Last week, we reported that Craig Hill, a prominent chemist at Emory University, and his colleagues at six other institutions are retracting three papers they published in the mid-2000s, two in the Journal of the American Chemical Society and one in Science.
We have now spoken with Hill, who walked us through the history of the research. According to Hill, the international team of researchers, after “unusually extensive experiments” felt they had enough evidence to publish their original articles
but all authors (and others) remained skeptical given the unprecedented nature of these compounds.
Hill’s lab continued to conduct experiments and probe the original data after the publications, he said. (Hill wrote a piece for Nature in 2008 explaining the significance of the research, which, among other things, might lead to better ways of harnessing solar energy.)

The Journal of the American Chemical Society (JACS) and Science are retracting three papers by Craig Hill and colleagues which, we’re told, have been the focus of intense scrutiny within the field since they first appeared in the mid-2000. Hill is an internationally renowned expert in catalysis who has won a slew of awards for his work.
JACS has acted first, issuing two notices recently about the papers it published. The first notice, for 2005’s “A Palladium-Oxo Complex. Stabilization of This Proposed Catalytic Intermediate by an Encapsulating Polytungstate Ligand,” states: Continue reading JACS, Science retracting three papers from leading Emory chemist Craig Hill
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
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
Last month, we (and others) reported that the Journal of the American Chemical Society (JACS) had temporarily withdrawn a paper by a former president of the society after a number of chemists pointed out similarities between the March 25 article and previous ones by the author, Ronald Breslow.
The paper had drawn puzzled looks thanks to an April 11 press release — since deleted — headlined “Could ‘advanced’ dinosaurs rule other planets?” In its note last month, the journal said: Continue reading JACS makes it official, retracting Breslow “space dinosaurs” paper for “similarity to his previously published reviews”
ShouWei Han, who has been forced to retract six papers from various physiology journals following an investigation into his work by his former employer, the University of Louisville, has added another one to his tally.
Here’s the notice, from the American Journal of Physiology: Lung Cellular and Molecular Physiology: Continue reading Retraction seven for Shouwei Han, this one in the American Journal of Physiology
Duplication has, as we noted on Twitter the other day, been tripping up more and more scientists. And now self-plagiarism has snared a prominent Columbia University chemist in a paper that left many people scratching their heads to begin with.
As reported by the Chembark blog and Nature, the Journal of the American Chemical Society (JACS) has pulled a paper by Ronald Breslow for alleged duplication. The page for “On Evidence for the Likely Origin of Homochirality in Amino Acids, Sugars, and Nucleosides on Prebiotic Earth,” originally published on March 25, now includes this: Continue reading JACS temporarily pulls “space dinosaurs” paper for alleged duplication
A group of researchers whose work has been under investigation at the University of Louisville has issued a correction for a paper in the American Journal of Respiratory Cell and Molecular Biology (AJRCMB).
The correction follows three retractions each in the Journal of Biological Chemistry and the AJRCMB, the latter of which made it clear that lab member ShouWei Han was responsible for the manipulations and duplications that brought down the papers. Here’s the new notice, which appeared in the March 1, 2012 issue of the journal: Continue reading Group investigated by University of Louisville corrects lung cancer paper after retracting six others
A partial retraction has joined the ten retractions and five corrections of Anil Potti’s papers, this one of a 2008 paper in Molecular Cancer Therapeutics. The move comes 14 months after the retraction of the Nature Medicine paper upon which much of the Molecular Cancer Therapeutics paper was based.
Here’s the notice: Continue reading A “retraction in part” for Anil Potti and colleagues, in Molecular Cancer Therapeutics
