MIT’s Technology Review just published its list of Top Ten Emerging Technologies for 2008.  One of the top ten items is NanoRadio.  TR’s description of NanoRadio begins with: 

If you own a sleek iPod Nano, you’ve got nothing on Alex Zettl. The physicist at the University of California, Berkeley, and his colleagues have come up with a nanoscale radio, in which the key circuitry consists of a single carbon nanotube.

Absolutely fascinating — and especially so since this technology could be considered one of the first true "nano-machines."  As an aside, nanotechnology-related technologies have made the "TR10" for each of the past three years — 2007 (Nanohealing), 2006 (Nanomedicine and Nanobiomechanics), and 2005 (quantum wires).
