Nuclear energy's clean air benefits gained added attention at a United Nations global warming conference here this week, both in a presentation to one of the conference's top officials by the international business community, and in a symposium in which experts explained how nuclear technology can contribute to the "flexibility mechanisms" that nations will use to reduce greenhouse gas emissions.
A Sandia laboratory technician who dreamed of a bus-sized vehicle that would fix potholes as it drove over them now holds a patent on the idea.The automated system requires only a single driver instead of a crew, and is equipped with a global positioning system and cell phone so that really large hazards can be pinpointed in location, and called in.
Work at Sandia to determine the reliability of microelectromechanical systems (MEMS) may mean that one day soon, most electronic devices will contain the micron-size machines. Their use may expand and change the electronics industry if they prove reliable.
Changes in student attitudes about marijuana, not a general rise in rebellious or delinquent behavior among the teen-age children of baby boomers, are driving recent increases in the use of the drug.
