A PNAS expression of concern appears — and so does its revealing backstory

with 19 comments

pnas 1113When retraction notices and expressions of concern appear, particularly those that are opaque, we try our best to find out what’s behind them, whether it’s better explanations or the steps that led to moves. Today, we have one story in which we’ve been able to learn a lot more than usual.

In April, Bas van Steensel, Wendy Bickmore, Thomas Cremer, and Kerstin Bystricky sent a letter to about 80 leading labs in nuclear organization and steroid receptor biology. It began (we’ve added some relevant links): Read the rest of this entry »

New method sinks newish paper…or does it?

with 6 comments

cover_2009_BB_viz_biomassThe timing on a recent retraction of a paper from Biotechnology and Bioengineering makes it a bit difficult to figure out what happened, but here’s a try.

An article first published online May 16th by a group of researchers at Brown University was retracted on June 1st, apparently because a new and better method for analyzing the data was developed…at some point.

The timeline is not exactly clear from the retraction, though we’ve reached out to the author and publisher and will update with any new information.

Here’s the (paywalled) notice for “High-level production of 3-hydroxypropionatein Escherichia coli and Saccharomyces cerevisiae by introducing part of the 3-hydroxypropionate/4-hydroxybutyrate cycle from Metallosphaera sedula”:
