Belts
allowed a single engine in a 19th-century
mill to drive many machines, some of them
floors away. Now that more mechanical devices
are being crammed onto computer chips, researchers
at Sandia National Labs are going back to
the future to recycle the belt concept.

Labs-on-a-chip
gain micro mixer
Put a few scratches in the right places and you've
got a blender-on-a-chip.
Starting
over speeds searches
Sometimes starting over is the fastest way to get
the job done. The trick is figuring out whether
the cause is hopeless or if you just need to make
a few adjustments.
Nudged
nested nanotubes may oscillate
Take both ends off a telescoped set of microscopic
carbon nanotubes, pull the inner tubes part of the
way out and let them snap back inside and they should
slide back and forth more than a billion times a
second, making for supersensitive sensors and timers.
Portfolios
boost quantum computing
Everyone knows that having a diversified portfolio
is the way to go. As it turns out this is true for
quantum computing, too.
