Listening to the whispers of individual cells

I just sent this in on another thread, the one about the neuron sounds, though, as I'd said on there, I don't think that was true mechano-acoustic recording, just an audio rendition of an electrical firing pattern...this one, by contrast, at least from what I've gleaned superficially thus far, does seem to be genuinely based on mechano-acoustic effect...which I actually found REALLY clever...the histopathogic acoustics of disease, per se, had, in fact, till I'd found this, never actually occurred to me, honest...this one REALLY got my mental gears spinning....
