- Djerrid, on 07/05/2008, -2/+111 In a normal world, like in the past, in order to create a radio you would need more than a signal periodic element to construct it. And it would need to be bigger than a few nanometers. It would also need to consist of more than a single molecule. I love living in the future.
- dsmx, on 07/06/2008, -2/+101Won't the RIAA ask for royalties?
- palewook, on 07/06/2008, -2/+71Metallica has already started it's anti-nanotube campaign..
- JJCDAD, on 07/06/2008, -3/+67It's science!
- inactive, on 07/06/2008, -3/+56RFIDs used to track single celled organisms?
- DestroyFascism, on 07/06/2008, -0/+51The CIA will love this
- HHP2K, on 07/06/2008, -0/+50Okay, holy *****.
Was I just listening to a song with relatively okay clarity.. from a radio that was almost less than 1 molecule thick?
Yes I was. Holy *****. - tian2992, on 07/06/2008, -0/+49It Works Bitches!
- ziggygazzo, on 07/06/2008, -0/+43Its on top of the charts and number one in our hearts. You're listening to WNANO....all nano all the time.
- philadelphia, on 07/06/2008, -2/+45You have to love science.
- crapmatic, on 07/06/2008, -0/+30The RIAA doesn't ask for anything.

Only becomes popular when MrBabyMan posts something! - cjhowe, on 07/06/2008, -2/+26Needs more cowbell.
- theOster, on 07/06/2008, -0/+19i love the phrase "orders of magnitude" - it's what keeps me excited
- inactive, on 07/06/2008, -0/+19I love how the first thing they decided to use this for was copyright infringement.
- inactive, on 07/06/2008, -3/+20Now they can make hearing aide sized mp3 players so you can listen to them in places that would have you remove them.
- GTanaka, on 07/06/2008, -0/+16Congratulations Dr. Zettl et al. Go Cal!
- overridemymind, on 07/06/2008, -3/+19Except this breakthrough has nothing to do with the way an MP3 player works. This is a reciever. All the nanotube technology does is take all the bitty little components of your average transistor radio and makes them infinitely smaller. What it does mean is smaller cellular phones, radios, anything with WIFI and the like (basically anything involving transmit-recieve capability)
However, since an MP3 player involves completely different components, which basically include a processor, a solid-state disk or standard hard disk drive, and a digital-to-analog converter -- no transmit-recieve functions involved here. (the ipod touch being an exception, due to its WIFI capability)
So, an earphone sized FM radio may be a possible use for this technology, an MP3 player (well, one worth half a damn, anyway) of that size is still currently impossible. In other words, this isn't the tech you're looking for.
Cheers,
overridemymind - Qeveren, on 07/06/2008, -0/+15I always joke that carbon nanotubes can do anything. Then something like this comes along, and they really CAN do anything. Augh! :)
- cygnus2112, on 07/06/2008, -0/+14Someone with a musical taste past Vanilla Ice and Ashlee Simpson?
- CeeJayDK, on 07/06/2008, -3/+14That's what SHE said.
- m0laria, on 07/06/2008, -0/+11You may be joking but that would actually be a legitimate use. For instance, tracking the movement of parasites through water streams or through animals to see where they affect the body, etc. This would be an alternative to radioactive isotope marking.
EDIT: Except I Forgot that studies are showing that carbon nanotubes are toxic to cells, as they can permeate the plasma membrane. Releasing a bunch of these into our water would be a very bad idea. - hotlatte, on 07/06/2008, -1/+11What is this news, like a year old? Technology Review had a story on this back in Februrary.

- cookingboy, on 07/06/2008, -1/+10I know, man...Apple used up the model name iPod Nano a few years too early...
- Smegzor, on 07/06/2008, -1/+10Pity they won't be able to use this in public in the UK (In case someone hears it) ;)
- jcannonb, on 07/06/2008, -0/+8That's what HE said.
- kelpee, on 07/06/2008, -0/+7I misplace my mp3 player and cell phone because they're so small......

- dafragsta, on 07/06/2008, -0/+7There's nothing conspicuous about wearing sunglasses indoors that wouldn't draw attention to the earbuds in your ears 2" from your eyes.
- cygnus2112, on 07/06/2008, -0/+7Honey, I Shrunk the Radio!
- overridemymind, on 07/06/2008, -0/+7Oh, yeah, because berkely is ALL about hoaxes when they announce a scientific breakthrough.
Buried for not thinking before you "speak" (read: type) - waydee, on 07/06/2008, -0/+7Would love to have more details, I really struggle to get my head around how nanotubes can do stuff like this.
- knobidy, on 07/06/2008, -1/+8... and take 3 damage.
- chr1syr, on 07/06/2008, -2/+8I also think I get it (but i'm taking a guess). The article mentions resonant frequency, i.e. where the natural frequency of the nano tube matches the carrier frequency of the FM signal. You can't see the tube at resonance as this is in the region of millions of times per second. It looks like the tube is also exited with a constant electro static source. As the frequency goes slightly above or below the carrier frequency the intensity of electrons emitted by the tube varies lineally in relation to the the amount of difference. As an FM signal is carried in the difference to the carrier frequency, these linear changes in electron emissions intensity represents the audio signal. A sensor is then used to measure this and send it off as an audio signal.
- pyro789x, on 07/06/2008, -0/+6Was I the only one that thought it was hilariously coincidental that the first song they picked up was "good vibrations"?
- dsoldier, on 07/06/2008, -0/+5Nanomachines... in the bloodstream? I know where this is going.
- jb0nd38372, on 07/06/2008, -1/+7Apparently thats what you both said.
- iDiggIt42, on 07/06/2008, -0/+5A swing and a miss.
- xceptionaly, on 07/06/2008, -0/+4We get signal
Main screen turn on - karmabandit, on 07/06/2008, -0/+4A few problems with that idea (sorry, technicalities suck)
1) Radio waves have a wavelength of about 1 meter, so you'd only know where it is to a precision of about a meter. And you probably know where it is with that precision anyway.
2) The nanotube radio needs a much larger anode and cathode to provide a bias voltage, both of which are much larger than the cell you're tracking.
3) The possible toxicity mentioned above, though this is something that could possibly be remedied. - ZippyV, on 07/06/2008, -12/+16Buried for using Quicktime.
- Fratz, on 07/06/2008, -1/+5It was implied by "places that would have you remove them."
- Texmurphy01, on 07/06/2008, -0/+3We will add your biological and technological....
Nah. - jbeardsl, on 07/06/2008, -0/+3If they were really thinking, they would have played Oingo Boingo's "Weird Science"
- CrazyEddie041, on 07/06/2008, -1/+3New release: the iPod Atto!
- drouk1556, on 07/06/2008, -0/+2The following information may or may not be cared about:
Ringo Starr attended the wedding of Clapton and Pattie Boyd, who the song is about.
http://en.wikipedia.org/wiki/Layla - davidbrown2, on 07/06/2008, -2/+4Will it blend?
- trevorh, on 07/06/2008, -1/+3I think the first song was actually "Good Vibrations" , "Layla" was just one of the first four songs that they recieved on it.
- agamoto, on 07/06/2008, -0/+2It's a series of tubes!
