Although you're unlikely to hear a couple of cockroaches chatting with one another, that doesn't preclude the possibility of critter communication. Researchers at Cornell have fully identified the exact molecular shapes of pheromones, the chemical walkie-talkies of the biological world, used by the brownbanded cockroach and the longhorn beetle. Scientists uncovered the chemical composition of the cockroach pheromone in previous studies, but until now the stereochemistry, or three-dimensional structure, remained a mystery. Last fall, components of the pheromone were first separated by gas chromatography. Next, the response of the insect's antennae (its olfactory senses) was monitored with an electroantennographic detector capable of recording minute electric signals, and this work led to a chemical roadmap of the pheromone. In order to ascertain the stereochemical composition of the pheromones, a team led by Professor Jerrold Meinwald of the chemistry department developed a synthetic method to produce stereoisomers. These stereoisomers were then compared to the original structure of the pheromone until a match was found. A heightened concern for the environment is driving the recent research in pheromones, and the results may lead to a more bio-rational pest control. Explains Prof. Meinwald, "This approach to pest control is based on understanding and using the species' own communication system. It is not toxic, not dangerous, and will not affect other species."

The College of Engineering at the University of Wisconsin is jumping on the slogan bandwagon with the Vision 2000 plan (gee, does this sound familiar?). The proposal outlines nine broad policy planks with a total estimated price tag of approximately $100 million. The Building for the Future mandate attempts to address the chronic shortage of space on campus by constructing an Engineering Centers Building with more than 140,000 square feet of labs, classrooms, conference rooms, and a student commons area. Expanded funding for extracurricular activities will encourage the development of leadership, teamwork, and entrepreneurial skills. Roughly $22.5 million will be allocated towards undergraduate scholarships and graduate student fellowships, and another $24 million will be dedicated to improving opportunities for underrepresented groups on campus. More endowed professorships will be offered in an attempt to recruit outstanding faculty, enhance research, and attract additional grant support. The Revised Professional Curriculum plank addresses the need for training faculty and administrative staff in the areas of Total Quality Management as a part of the TQM University Challenge. Last, but certainly not least, campus aesthetics will be considered, and steps will be taken to "beautify the campus." Just four years before the turn of the century, the Vision 2000 plan is still more of a lofty vision than a concrete reality, but the University of Wisconsin Foundation and Dean John G. Bollinger are attempting to change that.
