Some computers recognize voices, others recognize
faces. A smart chair under development at
Purdue University uses similar technology
to collect data from an entirely different
angle. The sensitive chair could eventually
prevent you from falling asleep at the wheel,
or remind you that slouching now will hurt
later. But can you truly relax in a chair
that tracks your every move?

Oversize
oddity could yield quantum computers
Strange quantum behavior is supposed to be confined to atoms and subatomic particles, but researchers have conjured a quantum effect in currents made of millions of electrons. Current that flows both ways at the same time could yield quantum computers.
Switch
narrows molecular-macroscopic gap
The bottom-up and top-down approaches to nanotechnology need to come together. Tethering gold nanoparticles to a surface with molecules that readily shed and acquire electrons is a step in the right direction.
Tiny
metal wires chart nanoelectronics
Though there's nothing small enough for them to
connect, researchers at Bell Labs have produced
metal wires only 10 atoms thick. When electronic
devices eventually get that small, researchers will
have a better idea what to expect.
Chip
techniques block power leakage
A set of computer chip design changes aims to do the equivalent of turning out the lights in all unoccupied rooms.
