"SILICON GUNPOWDER: to power nanoscale robots"
Michael Sailor describes his accidental discovery of a silicon form of "gunpowder" that is pointing the way toward integrating nanoscale explosives onto silicon chips, a technology that might provide microelectromechanical systems (MEMS) with a means for rocket propulsion.

"ROBOTS: Flying robotic insect slated to explore Mars"
Motivated by the notion that the Mars landscape may prove easier to navigate by air than with ground-based rovers, NASA is backing a research project to build toy-sized flying robots, modeled on the entomology of insects, that can hover like helicopters. Patented as "entomopters," the robots are on the drawing board of University of Missouri professor Kakkattukuzhy Isaac.

"ON-LINE HELP: Johns Hopkins Web site tutors EEs"
A Java-powered educational Web site at Johns Hopkins University offers fledgling EEs a chance to brush up on their electrical-engineering skills. The site, Signals, Systems and Control, uses interactive demonstrations to provide tutoring on 20 difficult electrical-engineering concepts.

"ANTI-TERROR: Infrared camera enlisted to battle bioterrorism"
A compact, powerful way to perform infrared spectroscopy could speed the quest for ubiquitous organic sensors to head off bioterrorist attacks. In 10 milliseconds, the shoe-box sized planar-array infrared (PA-IR) spectrograph identifies airborne chemical and biological weapons by deriving a unique "signature." By contrast, today's methods, using laboratory-scale Fourier Transform IR (FT-IR) spectrographs, can take up to 30 minutes.
