If
DNA can build a person, why not fast computers
or small parts? With a little bit of chemistry,
researchers have coaxed snippets of DNA to
self-assemble into logic circuits. The results
could turn a test tube of DNA into a supercomputer
or a nano-scale assembly line. Full

Quantum
quirk promises smaller circuits
Quantum weirdness lets a pair of photons shine on
half the area one would cover. In this light, computer
chips could get a lot faster.
Lab-on-a-CD
corrects itself
Four pockets of colorful chemicals mean that someday
taking a blood test could be as convenient as firing
up your CD player.
Linked
particles advance quantum computing
Quantum computers aren't around the corner or even
a sure thing, but a linked pair of quasi-atoms is
a step in the right direction.
