Hess, Eugene L. – Science, 1970
Traces the history of the molecular approach to biology from the late 19th century. Describes the development of investigatory techniques as well as of knowledge of molecular structure. (EB)
Descriptors: Biochemistry, Biology, Science History, Scientific Research
Peer reviewed
Norman, Colin – Science, 1983
Provides top-rated programs (by university) in biochemistry, botany, cellular/molecular biology, microbiology, physiology, and zoology. Overall scores included with each program were obtained from 1,848 biologists who were asked to rate programs in terms of faculty quality and their effectiveness in educating graduate students. (Author/JN)

Peer reviewed
Epstein, Emanuel – Science, 1972
Laments the neglect of discussion of active transport of plant nutrients from soil to root in general biology textbooks. (AL)
Descriptors: Biology, Botany, Editorials, Physiology
Peer reviewed
Shanmugam, K. T.; Valentine, Raymond C. – Science, 1975
Reports that as a result of our increasing knowledge of the molecular biology of nitrogen fixation it might eventually be possible to increase the biological production of nitrogenous fertilizer from atmospheric nitrogen. (GS)
Descriptors: Agricultural Production, Biochemistry, Biology, Chemical Industry
Peer reviewed
Holden, Constance – Science, 1985
The National Academy of Sciences suggests models for biomedical research which include a biology-wide information system with computerized database accessible from a multitude of dimensions. Links could help discover whether toxic chemicals have effects similar to hormones. Commonalities from molecules to ecosystems might restructure available…

Peer reviewed
Lewin, Roger – Science, 1980
Summarizes events of a conference on evolutionary biology in Chicago entitled: "Macroevolution." Reviews the theory of modern synthesis, a term used to explain Darwinism in terms of population biology and genetics. Issues presented at the conference are discussed in detail. (CS)
Descriptors: Biology, Conferences, Evolution, Genetics
Peer reviewed
Johnson, Horton A. – Science, 1970
Reviews applications of information theory to biology, concluding that they have not proved very useful. Suggests modifications and extensions to increase the biological relevance of the theory, and speculates about applications in quantifying cell proliferation, chemical homeostasis and aging. (EB)
Descriptors: Biology, Information Theory, Scientific Methodology, Theories
Peer reviewed
Botstein, David; Fink, Gerald R. – Science, 1988
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)
Descriptors: Biological Sciences, Biology, College Science, Cytology
Peer reviewed
Broad, William J. – Science, 1981
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)
Descriptors: Biology, Creationism, Educational Legislation, Elementary School Science
Peer reviewed
Lewin, Roger – Science, 1982
Summarizes the views of Ernst Mayr on the controversy over evolution which exists between physical scientists and biologists. Discusses the uniqueness of individuals, work by population geneticists and mathematical geneticists, complexity in nature, rates of change, modes of change, and the need to ask "why". (DC)
Descriptors: Biological Sciences, Evolution, Genetics, Higher Education
Peer reviewed
Magasanik, Boris – Science, 1988
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)
Descriptors: Biological Sciences, Biology, College Science, Cytology
Peer reviewed
Higginson, John – Science, 1970
Proposes an international research laboratory to investigate environmental factors in human health. By international cooperation unnecessary duplication and waste of resources can be avoided and long-term studies can examine various world-wide environments. (JM)
Descriptors: Biology, Ecological Factors, Environmental Influences, Environmental Research
Peer reviewed
Dawid, Igor B.; Sargent, Thomas D. – Science, 1988
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)
Descriptors: Biological Sciences, Biology, College Science, Cytology
Peer reviewed
Provine, William B. – Science, 1973
Examines historically the attitudes of United States and British geneticists on the topic of race crossing. Between 1930 and 1950 the attitudes changed from a condemnation of wide race crosses because of deleterious effects to a belief that such inter-racial crosses were at worst biologically harmless. (JR)

Kass, Leon R. – Science, 1971
Discusses ethical and social issues arising from the possible application of biomedical technologies providing control over life and death, human potentialities, and human achievement. Argues that "because we lack wisdom, caution is our urgent need," and proposes that systems of international control and regulation are needed. (AL)
