Crossed
nanowires compute

One
hope for nanotechnology is that it will provide
a replacement for today's silicon computer
chips before they run out of room for improvement.
Silicon nanowires are emerging as a front-runner
thanks to a team of chemists who build transistors
by making the tiny wires go with the flow.

Disappearing
links shape networks
Those annoying 'page not found' browser messages
turn out to have a lot to do with the underlying
structure of the Internet.
Stored
light altered
Storing a light pulse in a tube of gas seems like
magic, but isn't all that useful in itself. Controlling
the stored light, on the other hand, is a step toward
ultra powerful computers.
Flipping
flakes change color
Flipping microscopic flakes back and forth is one
way to add color to electronic paper. It could also
be a way to wrap objects like helicopters in chameleon-like
skin.
Evolution
optimizes satellite orbits
Applying Darwin's survival-of-the-fittest law to
satellite orbits could mean we need fewer of the
multi-million dollar communications machines.
