Electronic
paper promises computer displays that you
can roll up. Several research teams have made
the necessary plastic circuits, but the trick
is making them as fast as their silicon predecessors.
One speedy prototype shows promise. The next
step is actually putting it in a plastic screen.

Semiconductors
control quantum spin
Controlling the direction a quantum particle spins
opens the possibility of making superfast computers.
Researchers have used magnetic fields to control
quantum spin, but a microscopic electronic device
similar to a component in your CD player does the
job much faster. Better yet, it might serve as the
building block of a future computer chip.
Cold
electrons crystallize
Flow electrons over liquid hydrogen, freeze them
to almost absolute zero and they line up like a
layer of ping pong balls on a table to become a
solid. These electron crystals could serve as quantum
computing hardware.
Neat
not always organized
Piling papers on your desk top might be a pretty
good way of organizing things after all.
Single
molecule drives transistor
Bell Labs researchers have topped their feat of
making the key part of a transistor from a single
layer of molecules by getting it down to a single
molecule. Making a one-molecule transistor is suddenly
not so far-fetched.
