Scientists
would seem to hold one of the last occupations
threatened by automation, given the brainpower
and education involved. But equipping a laboratory
robot with artificial intelligence software
makes for a fair approximation of a scientist.
Faster gene and drug discovery could result.

Chemicals
map nanowire arrays
Minuscule grids of nanowires could enable smaller,
faster computer circuits. But there are two challenges
to getting nanowire arrays ready for prime time
-- finding ways of accessing any particular nanowire
junction, and connecting the devices to the outside
world. Chemically modifying the right junctions
could solve both problems.
Badge
controls displays
A small computer worn around the neck like a conference
badge is the key component of a system that makes
sure that nearby monitors and computer screens show
you what you want to see. Taking the badge in hand
turns it into an input device. The idea is to make
the environment more responsive without requiring
sophisticated computer equipment that can see, hear
and understand you.
Neural-chaos
team boosts security
The best way to send a secret message is to scramble
it with a random code, and an excellent source of
randomness is chaos. The trick is sharing the randomness
only with intended receivers. Grafting chaos and
neural networks makes this possible, even over public
channels.
