Closing loop, Science retracts Hill group oxo paper

Craig Hill

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:

Chemist Craig Hill, author of JACS and Science papers, explains the retractions

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.)

JACS, Science retracting three papers from leading Emory chemist Craig Hill

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:

Two more retractions in respiratory journal as University of Louisville completes investigation

Last July, we reported on four retractions by a group of researchers at the University of Louisville, and we noted that the scientists’ work was under investigation. That investigation has apparently concluded, according to a retraction notice in the American Journal of Respiratory Cell and Molecular Biology for two of their papers:

University of Louisville investigating work by team under review at Emory

On Tuesday, we reported that Emory University in Atlanta was looking into why a team of former researchers — now at the University of Louisville — had retracted three papers in the Journal of Biological Chemistry (JBC).

Today, we learned that the researchers’ home institution since 2009 is now investigating the work. A spokesperson tells Retraction Watch:

Emory looking into circumstances of three new retractions in the JBC

Emory University is looking into why the Journal of Biological Chemistry (JBC) has retracted three papers published by Emory faculty from 2005 to 2007, Retraction Watch has learned. The papers were:

Data fraud at Emory leads to retractions of three cardiology papers

An investigation by Emory University in Atlanta has led to the retractions of three articles containing falsified data, but the ambiguous wording of the notices leaves us wondering if they are implying more than they state.

Two of the papers appeared in the journal Arteriosclerosis, Thrombosis, and Vascular Biology. The notices in ATVB implicate a researcher named Lian Zuo, who worked in Emory’s division of cardiology.

Here’s one:
