| Computers
built from quantum dots have come two steps
closer to reality with prototype switches
that don't need electrical leads and a clock
that synchronizes the switches. Quantum dot
computers would be blazingly fast and require
hardly any power. This all assumes somebody
can figure out how to make the dots line up
neatly. Full

Researchers
peer into quantum dots
Making lasers and maybe even computers from quantum
dots should be easier now that researchers can spy
on their electrons.
Flexible
displays come into view
Someday getting a new monitor for your computer
could be as easy as tearing off a sheet of cellophane.
The key is plastic circuits.
NASA
gets snake robot off the ground
Slithering along the ground, slipping into crevices
and rearing up look like pretty efficient ways to
explore planets.
Vibrations
make electrons jump
When molecules start rocking, electrons know it's
party time. Researchers aiming to make molecular
electronic devices have another variable to think
about: molecular vibration.
