Second retraction appears for arcade game-like image manipulation

with 3 comments

In June, we reported on a retraction in Current Biology that came after a number of PubPeer commenters suggested that the authors had engaged in figure manipulation, memorably comparing watching the published videos to playing the old-school arcade game “Space Invaders.”

Now a second paper from the same team has been retracted from Biology Open after the authors “were unable to repeat the results.” The journal was unable to get in touch with first author Livana Soetedio, whom the University of Illinois at Chicago found had fabricated the data and images in both publications.

University of Utah investigation fingers chemistry grad student for misconduct

with 24 comments

acs nanoA second retraction has been issued in a case of research misconduct at the chemistry department of the University of Utah.

The first retraction, in August of 2013, got a lot of attention for how poorly faked the figures were. At the time, an expression of concern was issued on the paper that has just been retracted.

Today, we exchanged emails with Jeffery Botkin, the research integrity officer at the University of Utah, who ran the investigation into the misconduct. He summarized the report for us below. Read the rest of this entry »

cardresCardiovascular Research has retracted a 2010 paper by a group of prominent cardiology researchers in Brazil.

The reason: Image manipulation — which the authors say didn’t materially affect the conclusions of the paper.

The article, “FAK mediates the activation of cardiac fibroblasts induced by mechanical stress through regulation of the mTOR complex,” came from a group led by Ana Paula Dalla Costa, from the State University of Campinas.

Here’s the abstract of the study, which has been cited 19 times, according to Thomson Scientific’s Web of Knowledge: Read the rest of this entry »
