“Hijacked Cicadas Play Music Like a Cyborg Loudspeaker” (Video - 1mn)

  I would most certainly put such an experiment into the "science gone wild" category. Should you do it, just because you can? For the sake of understanding then? To advance science? For fun? The natural sound of these cicadas is not pleasant so fair enough then? 

Via: New Scientist:

Cicadas make noise with organs called timbals that have thick ribs joined by thin membranes that, when flexed, create a click. Doing this hundreds of times a second creates a continuous noise, with the pitch determined by the frequency of the flexes.

To take control of the timbals, the researchers implanted electrodes into seven large brown cicadas (Graptopsaltria nigrofuscata) and used signals from a computer passed through an amplifier to induce noises at precisely controlled pitches.

The team was eventually able to induce the cicadas to accurately play music, with the insects capable of reproducing tones over more than three octaves, from a musical note A at 27.5 hertz to a C at 261.6 hertz.
