Molecular-scale
computing is a fine idea, but connecting individual
molecules to conventional electronic circuits
is like trying to sew a button with rope.
A memory scheme that uses randomness to assign
molecules definite addresses is a step in
the right direction.

Cartoons loosen up computer interfaces
Classic cartoons stretch reality out of shape but
don't leave you wondering what's going on. Could
some of those exaggerated animation techniques make
computer interfaces easier to grasp?
Bioengineers
aim to harness bacterial motion
Figuring out how to move microscopic objects in
liquids is a tough problem. Fortunately, critters
have been doing that for billions of years.
Virtual
view helps run tiny factory
A digital stand-in lets researchers set up an assembly
line that is smaller than the eye can see.
Lasers
spin electrons into motion
Hitting a pool of trapped electrons with corkscrewing
light beams causes current to flow: it's another
advance in the fledgling field of spintronics, which
could lead to ultra low-power electronics.
