Describes the initially ignored research performed in 1900 by Archibald Garrod concerning the link between heredity and biochemical reactions. (MLH)

Some feminists have become discouraged because the theoretical and conceptual changes leading to a feminist science have not yet occurred. A scheme has been developed which charts the phases through which the disciplines in the social sciences and humanities progressed before reconceptualization from the new scholarship on women transformed those…

Discusses recent advances in culturing somatic cells of plants that now make it possible to apply the powerful techniques of microbial genetics to higher life forms. (Author/JR)

A brief summary of the year's activity. (BB)

The broad area of biochemistry is surveyed. Subtopics include nuclei acids, peptide hormones, cell surfaces, and enzymology. (MDR)

Discusses human nature and behavior and indicates that, with the rate of ecosocial change accelerating, understanding the nature of man has become a precondition to the enhancement of human individuality and to the very survival of our species. (Author/JR)

Discusses the conflicting evidence and points of view presented by scientists involved in research on the nature of memory. The research of one group supports a chemical basis for memory, while the other group presents evidence supporting an electro-physiological basis. (JR)

Discusses some of the current theories on aging, such as biological time clocks for certain cells and on-off switches for genes, that were offered as explanations at the 140th annual meeting of the American Association for the Advancement of Science (JR)

Discusses research in the use of hormones and viruses to control insect populations. Although entomologists do not think that pheromones, hormones, and viruses will completely replace more conventional chemical insecticides, they will become increasingly important and will reduce our dependence on traditional insecticides. (JR)

Two investigations are reported regarding grasshoppers and their behavior. Procedures and data are included and materials for further work are available. (PS)

Discusses the existence of spirals in nature in general, supplying many examples, and explains how a particular organism, Phycomyces, accomplishes this feat. (GA)

Discusses how handedness at one level may give rise to handedness at another. Presents examples from plants and animals, molecules, atoms, to elementary particles. Examines the chiral symmetry in life and when it starts. (YP)

Describes three experiments which investigated the behavior of "Colisa fasciata" males in full breeding condition subjected to competition for nest sites and a single female. Concludes that for these fish territorial dominance is established in a relatively short time, the period varying with the intensity of competition. (MLH)

This report, the second of a three-part study of Soviet space programs, examines their manned space programs and reviews their quest for a permanently manned presence in space.
