Patterns of Change Wireless Webs Researchers and system developers are proposing to solve many of the problems of wireless telecommunications by turning every device in the system into a node that can serve as a relay or repeater for the system and its network on an ad hoc basis. The result is a web of wireless devices that can accommodate comparatively large amounts of data; can manage changing data-traffic patterns, weather conditions, and user locations; and can navigate around physical objects that block traditional broadcast systems. Such systems have the potential for a growth pattern similar to that of the Internet and show the potential for being equally transformational. The problematic "last mile" to homes, businesses, and mobile consumers could see an affordable solution that is completely wireless. Page 2. Items Worth Noting Personal Solutions to Public Problems Personalized monitoring devices, such as a recently developed air-quality monitor the size of a wristwatch, raise the possibility that private citizens will be able to perform monitoring tasks that the government used to perform. Consumers may hold companies to higher standards than the government ever could. Page 5. Tying Maintenance to Manufacturing Lockheed Martin Aeronautics is building a new computer system that ties manufacturing, diagnostics, maintenance, and the maintenance supply chain into one massive real-time system for its new Joint Strike Fighter.

The New Frontiers of Environmental Genomics Researchers are extracting DNA directly from soil and water in order to take advantage of the huge diversity of life forms that they can’t cultivate in the lab.

An Internet Bid for Expertise Eli Lilly has posted to the Internet a list of more than 20 molecules in the hopes of finding people with expertise and ideas on how to produce the molecules efficiently. Cash rewards of up to $100 000 are in the offing. Page 8. |
