Five retractions for engineering duo in South Korea over duplication, fraudulent data

without comments

An engineering student in South Korea and a professor have retracted five papers from four different journals for reasons ranging from figure duplication to manipulated or fraudulent data.

Jae Hyo Park, who is pursuing his PhD, and Seung Ki Joo, a professor in the department of material science and engineering at Seoul National University in South Korea, appear on all five papers as first and last author, respectively.

According to an official at IOP Publishing, the retractions began when a third party contacted them last March about “potential misconduct” in a paper published earlier that year in one of its journals—Journal of Physics D: Applied Physics. The IOP official Simon Davies explained: Read the rest of this entry »

More co-author misconduct raises NIH neuroscientist’s retraction count to 8

Not again.

That’s the sound of learning that a third scientist you worked with committed misconduct.

In the last two years, we reported on two retractions for neuroscientist Stanley Rapoport, the result of misconduct by two different first authors. We’ve since discovered more retractions resulting from those cases — and a new retraction stemming from the actions of yet another co-author.  

Although the latest retraction notice doesn’t reveal the reason for retraction, both the journal editor and Rapoport — based at the National Institute on Aging (NIA), part of the National Institutes of Health (NIH) — confirmed to us that it is the result of misconduct by the last author, Jagadeesh Rao. According to Rapoport, a “number of retractions [for] Rao are still in the works.”

We asked Rapoport for his reaction to multiple cases of misconduct by his colleagues, including the two first authors we’ve already reported on, Fei Gao and Mireille Basselin:

Nothing gold can stay: gold nanoparticle paper retracted for figure theft

with 2 comments

matresexpA paper on gold nanoparticles has been retracted after the publisher learned one of the figures had a “high degree of similarity” to a figure published by other authors a few months prior.

According to the notice, it was two authors of the retracted paper themselves who pointed out the overlap. The first author, Pratap Sahoo, is not mentioned, although it does say all three authors agreed to retract. The corresponding author of the original paper told us he was unaware of the incident.

You can compare the figures for yourself – on the left is figure 6(a) from the retracted Materials Research Express paper, rotated 90 degrees. On the right is figure 4(e) from “Porous Au Nanoparticles with Tunable Plasmon Resonances and Intense Field Enhancements for Single-Particle SERS,” published in the Journal of Physical Chemistry Letters: Read the rest of this entry »
