As the crusade to outlaw the teaching of evolution changed to a battle for equal time for creationism, the ideological defenses of that doctrine also shifted, from biblical to scientific grounds. The development of "scientific creationism" is described, focusing on the intellectual leaders of creationism, particularly those claiming scientific…

By using intense pulsed coherent x-ray sources it will be possible to obtain magnified three-dimensional images of living elementary biological structures at precisely defined instants. Discussed are sources/geometrics for x-ray holography, x-radiation interactions, factors affecting resolution, recording the hologram, high-intensity holography,…

Discusses the high school framework and standards developed by the National Science Teachers Association in the subjects of physics, chemistry, biology, and earth and space sciences. (MKR)

Reviews events in the California courts surrounding a five-day trial concerning the teaching of biblical creation in the public schools. (CS)

Discussed are past work and recent advances in the use of electron microscopes for viewing structures immersed in gas and liquid. Improved environmental chambers make it possible to examine wet specimens easily. (Author/RH)

Discusses the problem of whether an explanation of the phenomena of life can be deduced from an exclusive reliance on causal relationship. Indicates that this exclusive reliance is not valid and adds the concept of anticipation. (GS)

Discusses the optimality of natural selection, ways of testing for optimum solutions to problems of time - or energy-allocation in nature, optimum patterns in spatial distribution and diet breadth, and how best to travel over a feeding area so that food intake is maximized. (JR)

Six books written in response to creationist arguments are reviewed. Indicates that the books should be of great utility in educating students in the sciences and in presenting the case for science, as separate from religion, to the uncommitted public. (JN)

Reports on the Balanced Treatment for Creation-Science and Evolution-Science Act requiring that "creation science" and evolution receive "balanced treatment" in classroom lectures, textbooks, library materials used, science and humanities, and other educational materials or programs in Louisiana public schools. (JN)

A rapid sequencing method for ribosomal RNA was applied to the resolution of evolutionary relationships among Metazoa. Describes the four groups (chordates, echinoderms, arthropods, and eucoelomate protostomes) that radiated from the coelomates. (TW)

Discusses the applicability and advantages of using yeasts as popular and ideal model systems for studying and understanding eukaryotic biology at the cellular and molecular levels. Cites experimental tractability and the cooperative tradition of the research community of yeast biologists as reasons for this success. (RT)

Stresses the importance of investigating bacterial mechanisms to discover clues for a greater understanding of cells. Cites examples of study areas of biological significance which may reveal information about the evolution of prokaryotes and eukaryotes and lead to a comprehensive theory of cell biology. (RT)

Discusses insights discovered from research into human biology that are raising possibilities for therapy, prevention of disease, and challenges to society in the form of ethical decisions about the appropriate application of genetic information. (Author/RT)

Considered are the effects of the Scopes trial on textbook publishers, textbook writers, and textbooks used in schools. The authors question whether it was a victory for evolutionists or for other groups. (RH)

Discusses the advantages of Xenopus laevis as an experimental animal in the study of embryogenesis in vertebrates. Summarizes the contributions of this system to the analysis of ribosomal and 5S RNA genes, and the diverse and highly productive applications of the oocyte injection technology. (RT)
