(小ネタ)再現はrepeat, replicate, reproduce

 
理研のウエブサイトでは「STAP細胞の再現性」を「Reproduction of STAP cells」と訳していました。「再現する」という動詞に関しては、repeat, replicate, reproduceが使われていました。

Natureの記事repeat the experiment
Wakayama’s genetic findings come less than a week after the senior corresponding author on one of the papers posted a protocol giving a more detailed explanation of the STAP method to help researchers to repeat the experiment. The move by Charles Vacanti, of the Brigham and Women's Hospital, in Boston, Massachusetts, was intended to address the fact that no one outside the team has yet claimed success in reproducing its method, despite more than a dozen independent attempts. A Brigham and Women's Hospital spokesperson told Nature News that Vacanti “is not speaking to media at this time”.

Experimental protocol
The protocol might just be complicated — even Wakayama has been having trouble reproducing the results. He and a student in his laboratory did replicate the experiment independently before publication, after being well coached by Obokata. But since he moved to Yamanashi, he has had no luck. “It looks like an easy technique — just add acid — but it’s not that easy,” he says.

Major stem cell study debunked on scientific social network
SCIENCE 14 MARCH 14

ResearchGate has found itself at the centre of an international debunking of a Japanese paper that claimed to have found a simple way to generate pluripotent stem cells.

The social network for scientists launched in 2008 as a push back against traditional academia and the peer review process. It has now launched Open Review as part of that platform, a system that lets users "publish an open and transparent review of any paper that you have read, worked with, or cited" with the central question always being "is this research reproducible?" Professor Kenneth Ka Ho Lee, chief of stem cell research at the Chinese University of Hong Kong, found the answer was no.

"We even repeated it three times -- we're quite confident it doesn't work," Lee told Wired.co.uk. "If we had only repeated it once it would not have been fair on the author."
