Lists 24 frequently asked questions concerning hydrogen as a fuel with several responses given to each question. Emphasized are hydrogen production, storage, transmission, and application to various energy-consuming sectors. Summarizes current findings and research on hydrogen. An extensive bibliography is included. (ML)

Described are developments in medical electronics and physiological measurement. Discussed are electrocardiology, audiology, and urology as mature applications; applied potential tomography, magnetic stimulation of nerves, and laser Doppler flowmetry as new techniques; and optical sensors, ambulatory monitoring, and biosensors as future…

The remarkable growth of Clark Atlanta University (Georgia), a historically black institution, is attributed to aggressive pursuit of federal grants for science and engineering. After the 1988 merger of Clark College and Atlanta University, the new administration made a commitment to high-level science education through a broad research and…

Uses air temperature profiles--a topic taught in beginning meteorology courses--to illustrate the ease of restructuring the teaching/learning environment as a problem-solving mode. Students access real-time information through Accu-Weather's interactive database. Students use the data to answer the question, "What happens to air temperatures…

Presented are 126 reviews. Categories include amateur astronomy, children's books, computers and astronomy, cosmic rays, cosmology, education in astronomy, galaxies, general astronomy, history of astronomy, life in the universe, physics and astronomy, pseudoscience, quasars and active galaxies, reference, solar system, space exploration, stars and…

Described is a laboratory in which students are confronted with rigs built from full-sized industrial machinery and equipment. Students must draw a flow sheet, dismantle and draw key components, reassemble the parts, operate the rig, and interpret the run data. The laboratory and the course built around it are discussed. (KR)

Discusses the advent of microscale experiments within undergraduate organic chemistry laboratories mainly resulting from environmental safety concerns involving waste disposal. Considers the cost savings in purchasing less reagents and chemicals, the typical glassware and apparatus, the reduced hazards from elimination of open flames, and other…

Describes Saskatchewan Indian Federated College's preprofessional, university-level science program and its focus on building math and science skills and on Indian culture, traditional medicine, current and future health care needs, and the goals of Indian people. Reports departmentwide enrollment increases. (DMM)

Discussed is a designer-drug technology called antisense which blocks messenger RNA's ability to carry information to protein producing sites in the cell. The applications of this drug to AIDS research, cancer therapy, and other diseases are discussed. (KR)

An activity in which students transform an ampicillin-sensitive strain of E. coli with a plasmid containing a gene for ampicillin resistance is described. The procedure for the preparation of competent cells and the transformation of competent E. coli is provided. (KR)

The potential of concept mapping, a learning strategy, coupled with assessments oriented toward problem solving used to facilitate meaningful learning, is examined. How students make and use concept maps in studying and the factors that influence the way they are made and used are discussed. Sample concept maps are included. (KR)

Investigations that facilitate experimental design, the concept of replication, data analysis, and other aspects of scientific study are described. A list of materials, the recommended plants, and the directions for building the hydroponics unit are included. (KR)

Examples from research that incorporate plants to illustrate biological principles are presented. Topics include dried pea shape, homeotic genes, gene transcription in plants that are touched or wounded, production of grasslands, seaweed defenses, migrating plants, camouflage, and family rivalry. (KR)

A way in which to shift the focus away from lecture and the professor during class time to student-centered discussion groups is presented. An exercise used in a course on chemical process analysis that uses the group discussion method is included. (KR)

Spreadsheets are well suited to many geochemical calculations, especially those that are highly repetitive. Some of the kinds of problems that can be conveniently solved with spreadsheets include elemental abundance calculations, equilibrium abundances in nuclear decay chains, and isochron calculations.
