Streisand Effect meets tough editors as journal retracts already-corrected paper by Rui Curi

with 10 comments

curiRui Curi — the Brazilian scientist who threatened to sue the now-shuttered Science-Fraud.org site for criticizing his work — has rung up his second retraction, this one for a paper that he corrected earlier this year.

A few weeks ago, we reported on the shutdown of Science-Fraud.org, a site dedicated to highlighting problems with scientific papers, thanks to legal threats. At the same time, we noted that Rui Curi, one of the authors whose work had been questioned — and whose lawyers had sent the site a cease-and-desist letter — ended up retracting a paper the site had questioned.

Now, Curi has corrected another paper that featured on Science-Fraud.org. Here’s the notice: for “Comparative toxicity of oleic and linoleic acid on human lymphocytes,” which was originally published in Life Science in 2006: Read the rest of this entry »
