Should scientific misconduct be handled by the police? It’s fraud week at Nature and Nature Medicine

with 33 comments

naturemed1213It’s really hard to get papers retracted, police might be best-equipped to handle scientific misconduct investigations, and there’s finally software that will identify likely image manipulation.

Those are three highlights from a number of pieces that have appeared in Nature and Nature Medicine in the past few weeks. Not surprisingly, there are common threads, so join us as we follow the bouncing ball. Read the rest of this entry »

ALS paper retracted for figure problems

cd&dA group of researchers in Ireland has retracted their 2013 article on a possible new method for treating amyotrophic lateral sclerosis — ALS, also commonly called Lou Gehrig’s disease — after identifying errors in several images in the paper.

The article, “Acidotoxicity and acid-sensing ion channels contribute to motoneuron degeneration,” was published online in Cell Death & Differentiation (and appeared in the April 1 print issue, although we think that was a coincidence…). Read the rest of this entry »

A biologist at University College London (UCL) has resigned his post and taken responsibility for “inappropriate figures manipulations” in three now-retracted papers.

Assegid Garedew, formerly a senior research investigator in Salvador Moncada‘s group, stepped down earlier this summer in the midst of an investigation that should be completed soon, Moncada tells Retraction Watch.

The three retraction notices for papers by Garedew and colleagues are all similar.
