‘[T]he authors plagiarised a large amount of text, but…retractions should not be used as a tool to punish authors’

David Sanders

In September 2018, I wrote to the managing editor of FEBS Letters with my concerns about the extensive textual overlap between a 2011 article by Sonia A. Melo and Manel Esteller and other articles, including some that were not cited, such as a 2009 article in the Annual Review of Pathology by Yong Sun Lee and Anindya Dutta.

The Melo and Esteller article has received considerable attention, and has been cited more than 375 times. 

My initial efforts were met with a response that the iThenticate software they used only identified overlap with the published Melo and Esteller article.  I then had to guide the editor in the proper use of the program – including searching for partial overlap – that would lead to the finding of a 29% overlap with Lee and Dutta. 

On October 4, 2018, after seeing the results, the journal said they would look into the matter.  

In April 2019 I asked for an update. There was no answer.

Why one biologist says it’s not too late to retract the “arsenic life” paper

David Sanders

An anniversary has prompted this reconsideration of the revolution in biochemistry that wasn’t: the “arsenic bacteria.” Just over 10 years have passed since an infamous Dec. 2, 2010, NASA press conference, which promised the revelation of “an astrobiology finding that will impact the search for evidence of extraterrestrial life.” 

Of course, nothing of the kind occurred. The carefully curated moment was less informative for its scientific value — in effect, nil — than for what it says about how years of attention-seeking and speculation in biology can drive an agenda. Equally concerning, despite the intervening decade in which other researchers debunked the overhyped result, is that the journal involved has yet to retract the article in question, allowing it to live in a zombie state.   

The announcement at the press conference was, to the disappointment of many, the supposed “discovery” of a microbe that could grow on arsenate in the absence of phosphate and incorporate arsenic instead of phosphorus in macromolecules such as nucleic acids and proteins that was being published in ScienceSteven Benner (referring to himself as a curmudgeon) was the only individual at the press conference who talked real sense by undermining the claims.   Mary Voytek, NASA Senior Scientist for Astrobiology (a position she still occupies) employed a Star Trek analogy:

Despite refutation, Science arsenic life paper deserves retraction, scientist argues

David Sanders

Yesterday, Science published two papers which undercut an earlier paper in the journal claiming to show evidence for an arsenic-based strain of bacteria. Guest poster David Sanders, a structural biologist at Purdue University who was involved in a Retraction Watch story in May, argues that the journal could have avoided publishing the rebuttals—a swift retraction of the original was (and still is) the better move.

Allow me to apologize from the start. This narrative is not a typical Retraction Watch post, because it contains a number of personal elements. However, it would be hard to separate my perspective from my experience.

I will begin by asserting that, despite Rosie Redfield’s many valuable contributions to refuting the Wolfe-Simon paper that have culminated with the publication of data she and other investigators have obtained, there was no need for Science to publish additional articles. The Wolfe-Simon paper never should have been published. The only responsible action on the part of Science would be to retract the original article.
