Two detailed retraction notices correct the cardiology record

jaccTwo American College of Cardiology conference abstracts published earlier this year in the Journal of the American College of Cardiology (JACC) have been retracted, one because the authors were actually measuring something other than what they reported, and the other because newer software invalidated the results.

Here’s the notice for “Worsening of Pre-Existing Valvulopathy With A New Obesity Drug Lorcaserin, A Selective 5-Hydroxytryptamine 2C Receptor Agonist: A Meta-Analysis of Randomized Controlled Trials” by Hemang B. Panchal, Parthav Patel, Brijal Patel, Rakeshkumar Patel, and Henry Philip of East Tennessee State University: Continue reading Two detailed retraction notices correct the cardiology record

Data artifact claims two fruit fly papers from leading UK group — who offer model response

jcbcoverA team of researchers led by Daniel St. Johnston, director of the Gurdon Institute at Cambridge and a prominent developmental biologist in the UK, has lost a pair of articles after finding that their data were unreliable. But rather than “correct” the record with subsequent papers, they’ve withdrawn the problematic work.

To our mind, this is a poster case of doing the right thing by science. We think the notices — as provided by the authors and reported by the journals — pretty much say it all, so we’ll let them speak for themselves, followed by some details St. Johnston shared with us.

The first article, “LKB1 and AMPK maintain epithelial cell polarity under energetic stress,” appeared in 2007 in the Journal of Cell Biology and has been cited 108 times, according to Thomson Scientific’s Web of Knowledge.

According to the retraction notice:

Pamela Ronald does the right thing again, retracting a Science paper

About a month ago, we reported on a retraction by Pamela Ronald, of the University of California, Davis, and colleagues. We noted then that this was a case of scientists doing the right thing. Ronald contacted us after that post ran, and let us know that there would be another retraction shortly. That retraction notice has now appeared, in Science: Continue reading Pamela Ronald does the right thing again, retracting a Science paper

Cancer cell line mixup leads to retraction

ccr 9-15At team of researchers at MD Anderson Cancer Center has retracted a paper after realizing that the cell lines they were using weren’t what they thought they were.

Author retracts materials paper for irreproducibility

tetrahedronA materials scientist in Turkey has retracted a paper in the journal Tetrahedron after realizing that there was more to the compounds he was studying than he thought.

The article, “Novel donor–acceptor type thiophene pyridine conjugates: synthesis and ion recognition features,” appeared in April and was written by Fatih Algi, of the Laboratory of Organic Materials at Canakkale Onsekiz Mart University.

Here’s the notice: Continue reading Author retracts materials paper for irreproducibility

It’s an epidemic! Another group does the right thing, retracting neuroscience paper

jneurosciAs the bumper sticker says, “Regime change starts at home.” Seems to be the case with scientists these days.

This month we have seen commendable instances of researchers retracting papers after identifying flaws in their own data — an outbreak of integrity that has us here at Retraction Watch applauding. (We’ve even created a new category, “doing the right thing,” at the suggestion of a reader.)

Today’s feel-good story comes from the lab of Karl Svoboda, of the Howard Hughes Medical Institute’s Janelia Farm Research Campus, in Ashburn, Va. Back in June, Svoboda and his colleagues published “Whisker Dynamics Underlying Tactile Exploration,” in the Journal of Neuroscience. Here’s what the abstract had to say about the study:

Doing the right thing: Researchers retract quorum sensing paper after public process

We’ll say it again: We like being able to point out when researchers stand up and do the right thing, even at personal cost.

In December 2011, Pamela C. Ronald, of the University of California, Davis, and colleagues published a paper in PLOS ONE,”Small Protein-Mediated Quorum Sensing in a Gram-Negative Bacterium.” Such quorum sensing research is a “hot topic” right now, so not surprisingly the paper caught the attention of other scientists, and the media, including the Western Farm Press. The study has been cited eight times, according to Thomson Scientific’s Web of Knowledge.

One of those scientists who took notice was Ronald’s UC Davis colleague Jonathan Eisen, who posted about the paper on his blog. That was on January 9, 2012. But if you go to that post today, you’ll see that Eisen struck through most of it, and added this comment: Continue reading Doing the right thing: Researchers retract quorum sensing paper after public process

Doing the right thing: Researchers retract two studies when they realize they misinterpreted data

protein scienceWhat do you do when new experiments show that you interpreted the data from your old experiments the wrong way?

Some scientists might just shrug and sweep those errors — and their previous papers — under the rug. But when it happened to Jeffery Kelly, of the Scripps Research Institute, and his colleagues, they decided to retract their earlier work.

Here’s the abstract of their new paper (we bolded a few sentences for emphasis): Continue reading Doing the right thing: Researchers retract two studies when they realize they misinterpreted data

A sad postscript: Paper by deceased researcher retracted

cancer researchIt was the last study ever published from prominent scientist Gerd Maul’s lab. And now it’s been retracted.

Maul was a highly cited cell biologist, with 30 papers cited at least 100 times, according to Thomson Scientific’s Web of Knowledge. He was also a well-known sculptor. When he died in 2010, he had a paper under submission at Cancer Research, which was published late that year.

This year, however, his co-authors found problems with the study. And as the notice — one of the most detailed we’ve ever seen — explains: Continue reading A sad postscript: Paper by deceased researcher retracted

Retraction of JBC heparan paper shows much to like

jcb726coverWe have knocked the Journal of Biological Chemistry in the past for what we believed to be needless — and unhelpful — obfuscation. And more recently, we have praised the journal for taking what we believe to be positive steps in the direction of greater transparency.

Here, again, we come not to bury JBC but to praise it.

The journal has issued a retraction for a 2011 article by a group of researchers in London, England, led by Stephen Perkins. The paper, “The solution structure of heparan sulfate differs from that of heparin,” purported to show that:
