Historically described are research studies which led to the current explanation of the two kinds of intracellular transport-axoplasmic flow and axoral transport. Models explaining their fundamental mechanism and the kinds of materials they convey are presented. (BT)

Herman the Ermine's teaching methods are closely aligned to an ancient Chinese verse from the Book of Tao. According to author Law Tsu, "Teachers who teach best teach with no words." (Author)

Results of spatial tests and analytical tasks indicate that girls tend to use the left hemisphere of the brain in processing all the tasks and use it much more so than boys on spatial tasks. (MP)

Discussed is the Cholodny-Went hypothesis which explains geo- and phototropic curvature in shoots in terms of a perception phase at the apex with a response at some remote site. Hormonal messages, lateral transmission of a stimulus, auxin concentration gradients, and what should be taught concerning this hypothesis are discussed. (DS)

Presents a key for the identification of 21 species of birds at Black Hill Conservation Park in Australia. Example on how to use this key is also presented. (HM)

This report details recent advances in fermentation biotechnology as presented by speakers at the 27th International Union of Pure and Applied Chemistry (IUPAC) Congress. Discussion centered around the use of bacteria, yeasts, and fungi as future sources of essential materials as food, fuel, and medicine. (BT)

Presents the results of a survey, conducted by the American Chemical Society Subcommittee on Physical Chemistry Examinations, on physical chemistry courses for life science majors. (BB)

Presents activities in which students play the role of cadets performing missions for the fictitious SETI (Search for Extraterrestrial Intelligence) Academy. Guides students toward an understanding of evolutionary forces and how they are affected by the physical environment. (JRH)

Traces the evolution of the nature of relationships and interactions between industry and academia in the life sciences. Discusses intellectual property and patents, publications, conflicts of interest, and cultural differences between academia and industry. (JRH)

Describes a learning game called The Business of Life that demonstrates the cellular processes of photosynthesis and respiration as business transactions. Incorporates the ideas that energy flows through ecosystems as well as through cells of individual organisms. Demonstrates the interdependence of living things and that processes at the cellular…

Presents a scenario-based anatomy exercise designed for middle schools students. Investigates the anatomy of alfalfa and sweet clover plants while focusing on seedling anatomy. (YDS)

Ordering principles, hierarchy, taxonomy, emergence, and decomposable systems are discussed. Examples of hierarchies are included. (CW)

States that the virus is not unique since it has been discovered in other primates as well as in man. Relates studies of viruses that indicate some have evolved disease-free coexistence with their animal hosts. (RT)

Provides a "template" for how a stream ecosystem functions. Discusses the physical and chemical factors of geology, light, current velocity, temperature, and energy sources. Describes functional groups of aquatic insects and the River Continuum Concept, a model of interaction that explains the spatial occurrence of aquatic insects. (LZ)

Tested Richard Duschl's triadic model of the growth of scientific knowledge against research practices of 10 accomplished life scientists. Reports that the scientists were willing to change their aims, methods, or theories and were both realists and relativists depending on the scientific discourse about the phenomena in question. Discusses…
