I'm not Robin, but this sounds like Janet Braam's work on calmodulin-like
genes in A.t.  If I'm not mistaken (it will be a first) the work was
published in Cell about 4 years ago.  Janet probably reads this group
but was too polite to toot her own horn.  The genes were called _touch_,
or so my memory tells me, and responded to all kinds of mechanical
stimulation but not, alas, music.
