By carefully coordinating DNA replication with other events in the cell cycle, the Caulobacter ensures that each progeny cell, swarmer or stalked, ends up with the correct number of gene-bearing chromosomes. Recent research shows that the master regulator itself is controlled by processes within the cell. ONR, the Naval Meteorology and Oceanography Command and the Naval Oceanographic Office are sponsoring the third annual Autonomous Underwater Vehicle Fest Nov. 3-9. Participating in the demonstration are the Autonomous Undersea Systems Institute, Florida Atlantic University, Lockheed Martin, Massachusetts Institute of Technology, Naval Postgraduate School and Woods Hole Oceanographic Institution. Miss. A Media Day is scheduled for Nov. 5.

Biomedical engineers at the University of Southern California have created the world's first machine system that can recognize spoken words better than humans can. In benchmark testing, USC's speech recognition system bested all existing computer systems and outperformed the keenest human ears. The system may eventually advance voice control of computers and other machines, help the deaf, aid air traffic controllers and others who must understand speech in noisy environments, and instantly produce clean transcripts of conversations, with each speaker correctly identified. With speech recognition capability, computer keyboards could become obsolete. The U.S. Navy is supporting the research for its potential benefits to Navy sonar.
