It turns out that wasn’t the only problem with the article — but we’re afraid that the glitch requires us to issue a correction.
The article, “Greatly enhanced continuous-wave terahertz emission by nano-electrodes in a photoconductive photomixer,” has listed Aaron Danner as the last — and, we’d assumed — senior author of the paper. But as Danner pointed out to us, that was a mistake by Nature Photonics.
Former National University of Singapore and University of Liverpool scientist Alirio Melendez has two more of the 20-something retractions suggested by the investigations into his work. Both appear in the Journal of Biological Chemistry.

The authors of a paper in Nature Photonics have been forced to walk back their article after learning from another group of researchers that their conclusions likely were an, ahem, optical illusion.
The paper, “Greatly enhanced continuous-wave terahertz emission by nano-electrodes in a photoconductive photomixer,” appeared in January 2012 and came from a team
led by that included Aaron Danner, an optics expert at the National University of Singapore. As the abstract of the paper explains (to physicists, anyway):
Paper with “missing or placed wrongly” controls retracted because there’s “no editorial mechanism to review the errors”

And then there were eight: Three more retractions for Alirio Melendez, all in the Journal of Immunology
Alirio Melendez, who has already retracted five papers and was found by one of his former universities to have committed misconduct on more than 20, has three more retractions.
Here’s the notice for “Antisense Knockdown of Sphingosine Kinase 1 in Human Macrophages Inhibits C5a Receptor-Dependent Signal Transduction, Ca2+ Signals, Enzyme Release, Cytokine Production, and Chemotaxis,” cited 68 times, according to Thomson Scientific’s Web of Knowledge: Read the rest of this entry »
A group engineers from Iran and Singapore have been forced to retract a paper in the Journal of Magnetism and Magnetic Materials after the article was found to contain incidents of plagiarism.
The article, “Magnetic properties of iron-based soft magnetic composites with MgO coating obtained by sol–gel method,” appeared in April 2010. Sometime later (we’re getting near the three-year mark from the date of publication) it seems, the journal learned that something was amiss with the paper.
Alirio Melendez, a former National University of Singapore immunologist whose story we’ve been following here since a retraction in September of last year, committed misconduct on an “unprecedented” scale, according to the university, involving more than 20 papers.
Nature’s Richard van Noorden has the scoop:
After a 19-month investigation, the National University of Singapore (NUS) today says that it has determined that one of its former scientists, the immunologist Alirio Melendez, has committed “serious scientific misconduct”. The university found fabrication, falsification or plagiarism associated with 21 papers, and no evidence indicating that other co-authors were involved in the misconduct, it says.
