Nanotubes Form World's Tiniest Radio!

I'm surprised the dimensions aren't listed!

What do you expect from the news media?

The real questions are:

Is this technology less expensive? Smaller? Better RF performance? Better thermal characteristics?

There aren't many facts here.

Would have been nice if they had given some measurements of the size and power. Does it fit in a wristwatch, an earring? How much smaller could they make all kinds of devices using this technology?

The remarkable thing here is that they built a complete and practical circuit. Sure it is only seven transistors, but the fact that the seven transistors work together, performing all the needed functions to convert radio signals into sound is remarkable. It means these carbon nanotube transistors are more than a simple laboratory curiosity. Yes I too would like to see the specs (power consumption, frequency limits, etc.). How to bias these things to make them work? Remember though, those simple 7 and 9 transistor radios in the 1960s that were the size of a pack of cigarettes and ran on a 9 Volt battery were the precursors to the modern digital age where we stuff hundreds of millions of transistors onto a piece of silicon the size of a man's thunbnail. I've worked at big semiconductor companies all my adult life but I actually knew some guys from the vacumn tube era who hoped these silly little transistors would go away. In my opinion this carbon nanotube technology bears watching.
