Craft Tech
The Craft Technology Group at the University of Colorado, Boulder, interweaves computation with craft materials both new and old. This Web site offers glimpses of innovative projects involving the use of software to design mechanical toys and paper sculptures, embedding computation and behavior in simple objects such as tacks and hinges, developing affordable three-dimensional printing, […]

Timing Is Everything: Implantable polymer chip delivers meds on schedule
A polymer microchip implanted under the skin could deliver multiple doses of medications at programmed intervals, eliminating the need for pills and injections.

Sweet-toothed microbe tapped for power
Using a newly discovered bacterium that both frees electrons from sugars and injects those charges straight into electric circuits, scientists have created a fuel cell that converts carbohydrates to electricity with extraordinary efficiency.

Wash Those Hands!
A Florida-based company is now developing a laser-based scanning technology to scout for dirty hands. Installed in restaurant washrooms or daycare centers, it could identify fecal traces — evidence that hand washing was incomplete. Indeed, these sensors might even be coupled to a lock that allows workers back into a kitchen after a restroom break, notes Richard Stroman, vice president of eMerge Interactive, which is applying for a patent on the system. Kitchen or food-processing-plant workers who don't pass the laser test would be forced to go back and lather up again.

Dream Machines from Beans: Legume proteins provide motion
Plant proteins swell and shrink in response to calcium, sparking new ideas for micromachines.
- Tech
Channeling light in the deep sea
Light-conducting fibers that naturally sprout from certain deep-sea sponges may hold lessons for makers of optical fibers for telecommunications.

Virtual stampede sees faces in crowd
A new computer model based on particle interactions suggests ways to prevent a panicked crowd from stampeding.
- Tech
Memory Enhancers
Engineers take aim at increasing the density of data storage on magnetic media.
- Tech
Smart dust can swarm target
Microscopic mirrors can swarm a target and produce an optical signal that identifies the target to the observer.
- Tech
Mind-Expanding Machines
Researchers have designed computer systems aimed at amplifying human thought and perception, such as a new type of cockpit display for aircraft pilots that exploits the power of peripheral vision.
