This paper: http://www.plosbiology.org/article/info%3Adoi%2F10.1371%2Fjournal.pbio.0050177

Uses an older form of the Public Domain Declaration (probably) that precedes cc0, we suspect this guy:
http://creativecommons.org/licenses/publicdomain/

We probably need to add that as a license and then use the following text as the search term:
