| The
tiny lasers used in devices ranging from CD
players to surgeons' scalpels are made from
the same expensive, brittle material as computer
chips. By applying a carefully tuned electrical
charge to the organic crystal tetracene, researchers
at Bell Labs have demonstrated a cheaper,
more flexible alternative. Full

Nanotubes
make microscopic bearings
Notions of building machines out of individual molecules
may seem far-fetched, but a key component, nanoscale
bearings, already exists.
Integrated
inputs improve interactivity
You can talk to computers and you can point things
out to them. Researchers at Georgia Tech are giving
computers a fighting chance of understanding what
you mean when you do both at the same time.
Microorganisms
infect computer chips
Someday computer makers might deliberately build
bugs into their products and their customers might
be happy about it.
Sandia
brews cheap telecom laser
A little alchemy can go a long way, especially when
the result is a cheaper laser powering that call
home on Mother's Day.
