Radio ga ga

Digital audio broadcasting? Radio over your TV? Wi-fi? All soooo last year, darling. Some Stateside boffins with too much time on their hands have invented the first all-nanotube transistor radio. That's right - a radio that is smaller than a grain of sand! This may well have serious technological implications for the future of mankind, but what happens if you forget where you left it? Oh, but the battery is bigger than a double decker bus. We're kidding about the second bit.
