stores light pulse
computers will need to be able to transmit
information using light. The question is how
do you store that information? Researchers
took a step in the right direction last year
by storing light pulses in gas atoms. But
it's probably not a good idea to build computers
using vapor. Storing light pulses in a crystal
is more like it.

In this age of miniaturization, it seems that you
can shrink just about anything and put it on a chip
-- even rocket engines.
sort gender in a binary world
Analyzing voices as well as faces gives computers
a good chance to tell girls from boys, at least
if they're facing the right way and are in a relatively

Fragile quantum information is hard enough to preserve
inside quantum computers. Sending it across networks
is a tremendous challenge.
computer readout glows
Computing using DNA has the potential to solve certain
problems very quickly because millions of molecules
can work on the same problem at the same time. One
problem is figuring out how to read the answer.
Getting the right pieces of DNA to glow could be
