Second retraction appears for Mart Bax

ethnosRetired Dutch anthropologist Mart Bax made a career out of making up papers, many of them on the Bosnian genocide.

He retired from the Free University in Amsterdam in 2002. It wasn’t until 2013 that the university published a report indicating that Bax never published 61 of the papers he listed on his CV, and many of the real articles were based on fabricated data.

Publisher Taylor and Francis retracted one of Bax’s papers from Ethnic and Racial Studies in April. Now they’re retracting a second, from Ethnos, using almost identical language.

Here’s the notice: Continue reading Second retraction appears for Mart Bax

Stem cell study retraction produces useless notice

int j stem cellsWe don’t have much to go on here, for a retraction from the International Journal of Stem Cells. 

Here’s what we do know: Dental researchers at several universities in Egypt, including Cairo University, Future University, and Misr University published a paper together. According to the article, they gave dogs oral ulcers and then injected the ulcers with either fat-derived stem cells, bone marrow stem cells, or saline. The researchers conclude that the fat stem cells, also known as adipose derived stem cells, helped the dogs heal.

Unfortunately, we have no idea what went wrong, because the retraction notice is useless. Here in its entirety is the notice for “Adipose Stem Cells as Alternatives for Bone Marrow Mesenchymal Stem Cells in Oral Ulcer Healing”: Continue reading Stem cell study retraction produces useless notice

Nature Cell Biology insulin paper retracted over antibody problems

nature cell biologyNature Cell Biology article on insulin regulation has been retracted after scientists noted that the antibodies used in their research were not as specific as they had previously believed.

The notice is clear on the problems with the science, which together “call into question the main conclusions of the paper.” Three of the paper’s five authors were employed at Novartis at the time of publication.

Here’s the notice for “Wolfram syndrome 1 and adenylyl cyclase 8 interact at the plasma membrane to regulate insulin production and secretion”: Continue reading Nature Cell Biology insulin paper retracted over antibody problems

“Incorrect data” kills apoptosis paper

Screen Shot 2014-12-19 at 5.52.16 PMFrontiers in Pharmacology has retracted a paper on baicalin, an antioxidant sold in health food stores, because it had both “incorrect data and invalid statistical analyses.”

A comment on PubPeer notes that one of the figures (see image to the right) contains two similar-looking flow cytometry images labeled with different values, which could be what the retraction is hinting at.

Here’s the notice for “Baicalin induced dendritic cell apoptosis in vitro”: Continue reading “Incorrect data” kills apoptosis paper

Paper recommending calorie limits on Happy Meals retracted

A paper estimating the effects of limiting fast food meals with toys to under 550 calories has been retracted after concerns arose regarding the scientists’ use of an outdated model for estimating weight changes in kids.

The paper estimated that kids who eat fast food twice a week would avoid gaining two pounds a year if calorie limits are imposed on meals with toys. However, everyone we spoke to, and the notice, indicated that their estimate was inaccurate.

Here’s the notice for “Modeling Potential Effects of Reduced Calories in Kids’ Meals with Toy Giveaways”:

Does irony have a place in science?

sciengethicsTake us at our word when we tell you this isn’t some exercise in meta-irony or meta-criticism or any other meta-bullshit, but a pair of researchers at Drexel University in Philadelphia have published a paper calling for an end to irony in science.

First, some background: In 2001, an Israeli researcher named Leonard Leibovici wrote a letter to the famously lighthearted Christmas issue of the British Medical Journal describing a randomized controlled trial in which intercessory prayer at a distance — in other words, people praying for other, sick people — was found to improve the health of patients with bloodstream infections. All the more remarkable was that this prayer was “retroactive,” as in, it purportedly occurred years after those sick patients had either left the hospital or died. Continue reading Does irony have a place in science?

Peer review isn’t good at “dealing with exceptional or unconventional submissions,” says study

pnascoverOne of the complaints about peer review — a widely used but poorly studied process — is that it tends to reward papers that push science forward incrementally, but isn’t very good at identifying paradigm-shifting work. Put another way, peer review rewards mediocrity at the expense of breakthroughs.

A new paper in the Proceedings of the National Academy of Sciences (PNAS) by Kyle Silera, Kirby Leeb, and Lisa Bero provides some support for that idea.

Here’s the abstract: Continue reading Peer review isn’t good at “dealing with exceptional or unconventional submissions,” says study

Paper that formed basis of study retracted earlier this year retracted itself, from Science

science dec 2014Back in May, we reported on a retraction from Molecular Cell that referred to a 2012 study the same group had published in Science. (A few weeks later, the lab head told us just how painful the process was.)

Now, the Science paper has been retracted. Here’s the notice: Continue reading Paper that formed basis of study retracted earlier this year retracted itself, from Science
