A milestone on the road to ultrafast computers
Article Abstract:
Using tunnelling magnetic junction random access memory, or tmj-ram, scientists demonstrated reading and writing times close to 10 nanoseconds, a six-fold increase over current technology. These new microelectronics, called 'spintronics,' draw on 2 characteristics of quantum mechanics: spin and tunnelling. By ordering the random up and down 'spin' of electrons, researchers create the binary state that is the basis for computer functions. Tunneling is a quantum quality by which current passes from one metal layer to the next, flipping its spin. The combination of these two features allows the memory chip to retain data when it is off, yet hold large amounts of data which can be accessed quickly.

Bridging two worlds to make on-line digital music profitable
Article Abstract:
Garageband.com is starting a Web site where musicians will upload music for consumers to download, listen to and rate. Starting next year, each month the most popular music will win a recording contract. The music files will be in MP3 format. The business was started by Tom Zito, Amanda Lathroum, and Jerry Harrison
