Developments to Watch
-- For 60 years, a Dow Chemical Co. cellulose derivative called Ethocel has been used to make everything from plastic water canteens to controlled-release agents for prescription drugs. Now, Dow is thinking about an edible version. The idea is to exploit Ethocel's film-forming qualities to bind mineral supplements to rice, which governments in poor countries could distribute to help combat malnutrition.
-- The U.S. Air Force is taking virtual reality to new heights. A lab at Wright-Patterson Air Force Base in Ohio is using Silicon Graphics Inc. computing power to cover a 35-foot-high dome with high-resolution images (below). The goal: to simulate cockpit experiences that will prepare pilots for the 21st century.EDITED BY NEIL GROSS
