An interesting article but they didn't ask the question which was ringing
in my ears throughout: how do you get an electrical signal from the cilia?
It's one thing to grow arrays of carbon nanotubes on a plate, but another
to get an electrical signal when they bend! This is the novel science of
the whole project, and they didn't say a word about it. Very frustrating!
