Sounds interesting.  I look forward to what the bloggers have to say about
it, and to seeing this paper online.  Or maybe I'll make a trip to the local
med-school library and xerox it.

But I have to say that the ScienceNOW article didn't give me a very warm
feeling about this.  Especially the picture of what I am pretty sure is
not a bacterial flagellum.  I'm not an expert, but it looks more like two
eukaryotic flagella (or maybe four) in a dinoflagellate.
