Biologists delete paper from literature after realizing they’d deleted too many genes

Researchers deleted more genes than they bargained for in a Drosophila strain, a mistake that resulted in a retraction of a paper from 2007.

Ron Wides, a biologist specializing in pattern development at Bar-Ilan University, Israel, and colleagues have retracted a paper published in Mechanisms of Development after his lab found that their technique to delete the Ten-a gene ended up deleting other nearby genes, too.

It was deletions of other genes, and not Ten-a, that killed the fruit flies, Wides concluded. His group had also concluded, erroneously, that Ten-a is what’s known as a “pair-rule” gene. Fruit fly embryos develop in stacked segments, like tubes of Pringles; pair-rule genes guide the development of alternating segments. Those other loci, and not Ten-a, caused lethality and caused the flies to develop improperly early, Wides concluded.

Paper claiming hottest 60-year-span in 1,000 years put on hold after being published online

The authors of a study of Australasian temperatures over the past millennium have put the print publication of an online-first study on hold after errors were identified in the records they used.

Here’s how RealClimate.org summarized the findings of the original paper, which was published in mid-May:

The conclusion reached is that summer temperatures in the post-1950 period were warmer than anything else in the last 1000 years at high confidence, and in the last ~400 years at very high confidence.

The page at the American Metereological Society site where the paper used to be now reads: Continue reading Paper claiming hottest 60-year-span in 1,000 years put on hold after being published online

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

Korean stem cell investigation expands to another researcher, and more papers

Last month, we brought you the story of Soo-Kyung Kang, a Seoul National University stem cell researcher who has now retracted four papers amidst questions about image manipulation in a total of 14 studies. That story has drawn a great deal of attention in Korea, with comparisons to the Woo-Suk Hwang scandal, and has even led to a profile of Retraction Watch in the Seoul Daily, one of Korea’s largest newspapers.

We’ve now learned that the investigation has grown to 25 papers after an anonymous whistleblower warned about possible data fabrications in another paper by Kang, an associate professor of veterinary biotechnology, and Kyung-Sun Kang, director of the Adult Stem Cell Research Center in the same department (but no relation). And Soo-Kyung Kang was investigated in 2010, according to the Korea Herald.

The researchers’ labs are also under lockdown Continue reading Korean stem cell investigation expands to another researcher, and more papers

FASEB J retracts 15-year-old study after author comes forward, but universities decline to investigate

The FASEB Journal — FASEB stands for the Federation of American Societies for Experimental Biology — is retracting a 15-year-old paper without the consent of all of the authors, despite what seem like valiant attempts to figure out exactly what went wrong.

Here’s the notice for the University of Bern-University of Urbino paper:
Continue reading FASEB J retracts 15-year-old study after author comes forward, but universities decline to investigate

Is a retraction in the works for America’s Got Talent star?

We try to avoid straying beyond science on this blog, but sometimes — as in the case of This American Life, which not long ago had to retract a segment featuring Mike Daisey that had been critical of the conditions in a Chinese factory linked to Apple — we can’t help ourselves. Like now.

A retraction might be the next tune for one Timothy Michael Poe, who has been a contestant on America’s Got Talent. According to the Associated Press, the aspiring country singer told the show’s judges that:

Former Millennium Villages Project staffer responds to critical Nature editorial

Last week, we wrote about a correction of a heavily criticized paper in The Lancet by the Millennium Villages Project, a large aid program. Paul Pronyk, director of monitoring and evaluation at Columbia University’s Center for Global Health and Economic Development, which runs the Project, left his job shortly after writing an explanatory letter that accompanied the correction.

That correction had come after a letter to The Lancet, but also after Nature had raised issues in an editorial. Nature’s editorial concluded: Continue reading Former Millennium Villages Project staffer responds to critical Nature editorial

Two new corrections for Utah group that retracted two Cell Metabolism papers for missing notebooks

We have an update on the case of a University of Utah lab that retracted two Cell Metabolism papers last month after a fired lab technician disposed of two lab notebooks without permission. The team has now corrected two other papers, one in Blood and the other in the Journal of Clinical Investigation.

Here’s the notice from Blood: Continue reading Two new corrections for Utah group that retracted two Cell Metabolism papers for missing notebooks

Premature delivery? Paper on rapid assay for ruptured placenta pulled for “mishandling” of tests

The other day we brought you the story (well, not quite a STORY) of a group of researchers who had to retract a paper in the Journal of Computational Chemistry because of a “computation error.” We still don’t know what that means.
