gain virtual faces

For
decades, forensic experts have identified
the dead by using clay to sculpt faces on
skulls. The effort to computerize the process
has taken a big step forward with a tool that
builds virtual muscles and skin on a three-dimensional
skull scan. The models can even be animated
to show different facial expressions.

explodes virtual buildings
Being immersed might be a good way to play Doom,
but isn't necessarily the best way to watch the
action unfold. Software that takes the tops off
digital buildings could turn computer games into
a spectator sport. It could also make it easier
to evaluate trainees as they go through their paces
in simulators.
Tool
blazes virtual trails
Navigating through large computer models like ships
and manufacturing facilities is often a frustrating
experience that leaves you drifting along, dream-like,
with little sense of moving through a real space.
Software that keeps your virtual feet on the ground
could bolster the realism of three-dimensional environments.
Quantum
computer keeps it simple
Quantum computing is a great idea, but it's too
soon to tell whether manipulating the quantum world
to the necessary degree will ever be a manageable
undertaking. Controlling fleeting quantum particles
usually requires making extraordinarily precise
devices. A proposal that calls for chaperoning pairs
of particles and getting all of the particles in
a quantum computer to sing the same tune could ease
this burden.
