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)

Outlines the use of modeling in science teaching. Describes a study in which two parallel groups of year seven pupils modeled concepts of cell structure and function as they produced two- or three-dimensional representations of plant and animal cells. (Author/CCM)

Researchers at National Jewish Medical and Research Center have demonstrated that dilute bleach not only kills common household mold, but may also neutralize the mold allergens that cause most mold-related health complaints. The study, published in the Journal of Allergy and Clinical Immunology, is the first to test the effect on allergic…

Research is so inextricably embedded within the teaching in the bioscience disciplines that many of us do not question that there is linkage between teaching and research--we simply know that it is true as part of our discipline culture. We, as bioscientists, have written this essay for the bioscience academic community. We start from the point of…

The laboratory-learning environment needs to become more exploratory and undergo a transformation from its traditional confirmatory role in the learning of science. This is necessary to effectively allow students to achieve scientific literacy. The availability of powerful tools for data collection and analysis provides an opportunity for students…

This annual report of the Assembly of Life Sciences (ALS) covers the fiscal year beginning July 1, 1977, and ending June 30, 1978. This report has four major sections on the Executive Office, the Division of Biological Sciences, the Division of Medical Sciences, and the Board on Toxicology and Environmental Health Hazards. The activities in each…

Discusses the behavior, housing, care, diet, and feeding of painted turtles. Also suggests several classroom activities and provides guidelines related to long-term captivity and human disease prevention. (DH)

This issue of Exploratorium Magazine focuses on Antarctica. Antarctica has one of the most extreme climates in the world with an untouched environment inviting researchers with great opportunities for study. This issue describes the journey of four Exploratorium staff members to frozen Antarctica. Chapters include: (1) "Life at the Bottom of…

Summarizes recent findings that help in understanding how evolution has brought about the diversity of plant life that presently exists. Discusses basic concepts of evolution, diversity and classification, the three-line hypothesis of plant evolution, the origin of fungi, and the geologic time table. Included are 31 references. (CW)

Discusses the background and events which lead to a career devoted to plant biochemistry and the study of vitamin synthesis. Describes laboratory studies which demonstrated that, in mammals, vitamin A is formed from beta-carotene as it crosses the intestinal wall. (RT)

Demonstrates the magnitude of an extinction event by using a simulation to illustrate the massive nature of the loss of a family and the number of species that perish to achieve that result. (RT)

Provides a format for the identification of fossils when introducing geologic time in the laboratory. Presents an organization of fossils into three major groups based on radial, bilateral, and no apparent symmetry. States that this method reinforces student learning and provides for an orderly approach to fossils. (RT)

Offers examples of problems that assess student ability to recall, handle, manipulate, and interpret data and also reinforce basic knowledge of cell biology. The questions, purposely designed for first-year students, complement formal lectures and practical classes given in the subject. Illustrates the range and types of material which cell…

Describes a science experiment involving plant seeds where students observe the germination and plant growth. (YDS)
