We have constructed a fully functional, fully integrated radio receiver, orders-of-magnitude smaller than any previous radio, from a single carbon nanotube. The single nanotube serves, at once, as all major components of a radio: antenna, tuner, amplifier, and demodulator. Moreover, the antenna and tuner are implemented in a radically different manner than traditional radios, receiving signals via high frequency mechanical vibrations of the nanotube rather than through traditional electrical means. We have already used the nanotube radio to receive and play music from FM radio transmissions such as Layla by Eric Clapton (Derek and the Dominos) and the Beach Boy's Good Vibrations. The nanotube radio's extremely small size could enable radical new applications such as radio controlled devices small enough to exist in the human bloodstream, or simply smaller, cheaper, and more efficient wireless devices such as cellular phones....

Amazing. But radio is almost dead.
Not in the UK. Radio 2 is supposed to have the highest audience on the planet, and there are around 150 pirate stations broadcasting in the UK at any particular time.

They said the days of radio were numbered when they invented the music video in the sixties, and again when MTV started broadcasting nearly 30 years ago, but as long as people drive cars, or ride trains and buses, there will always be an audience for broadcast radio.
I listen to BBC Radio 1 on Sirius, and it is suprisingly good. Much, much better than American radio.
Hmmm. "Traditional" Radio may not be flourishing, but RF devices are multiplying...

Psst: The nanotube radio's extremely small size could enable radical new applications such as radio controlled devices small enough to exist in the human bloodstream, or simply smaller, cheaper, and more efficient wireless devices such as cellular phones.

But really ? The local NPR station just built a new broadcast station nearby....last year they upgraded the 2 older ones they already have to higher power transmitters.... ;-)

OMG!!! And as I saw the number 200 and the symbol nm, my jaw almost touched the floor. :D WOW!!! Still can't believe that! Can this be beat???

eventually one gets to the atomic level and can go no smaller, I suppose...
Yea, you think that, and than it gets smaller, like this one now! :D

It's interesting that they named the tracks that they received like these were some tests of the device, rather than simply stating which stations and frequencies - after Google hits? L
