wires turn chips inside out
nanowires are a great hope for making computer
chips when today's technology maxes out in
a decade or so. But researchers have a long
way to go to figure out how to connect millions
of these wires into useful devices. A new
recipe for making the nanowires could simplify
things by putting the device in the wire instead
of the other way around.
robots share the load
A pair of NASA robots are of one mind as they go
through their paces in the real world.
take tiny temperatures
Carbon nanotubes 700 atoms wide and filled with
the metal gallium can be handy thermometers for
measuring temperatures in the smallest of places.
scheme envisions DNA origami
DNA is probably the most talented molecule around.
It already builds every living thing on the planet,
and researchers are beginning to use it for computing.
Next up: three-dimensional structures.
switch flips atoms
Quantum computers can theoretically process and
store information in the spins of atoms, but exactly
how they will accomplish the feat remains an open
question. An experiment that controls the spin of
atoms in a semiconductor sheds some light on the
