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)

A treatment of exponential growth and decay is sketched which does not require knowledge of calculus, and hence, it can be applied to many cases in the biological and medical sciences. Some examples are bacterial growth, sterilization, clearance, and drug absorption. (DF)

Continuation of life and evolution as criteria for development of a value system are analyzed. Discussion is based on an awareness aspect of evolution which promotes a greater harmony of response with existing and emerging environmental conditions. (BL)

Outlines scientific history and the gradual understanding of the evolving universe; speculates on the "purpose" of the world and man's role in it. (AL)

Raccoons are a successful group of animals because they are able to defend themselves and they have characteristics which give them a remarkable ability to adjust or adapt. The raising of captured baby raccoons can cause survival problems for the animals. (CM)

Lists a number of books written by Charles Darwin, selected to indicate the depth and breadth of Darwin's biological interests. Each entry is described with a short annotation. Also provides a reading list of references about Darwin's life. (CS)

Describes differing concepts of nature held by systematists from 1789-1859, connections between these concepts, and how they saw relationships among groups and made classifications. Discusses what these systematists intended their classifications to represent and how these intentions relate to classifications used by twentieth-century biologists.…

Designates four challenges for a theory of evolutionary pedagogics which result from the theoretical progress made in biological science: (1) subjectively perceived autonomy; (2) teachability; (3) preparation for future life; and (4) the reality norm dilemma. Argues that these confrontations are the theoretical challenges for the further…

Responses from 559 Korean nurses indicated that 94.9% felt deficient in biological sciences knowledge, especially when conducting assessments. They felt bioscience course content was not related to clinical practice; 61% wanted bioscience integrated into a nursing model and taught by nursing faculty. (Contains 16 references.) (SK)

Describes the planning, research, and development of the BIOSIS Connection, an online reference service targeted to researchers in the life sciences. Product testing and preliminary response to the system are discussed, and highlights and disappointments of the project are summarized. (two references) (MES)

This is an update of a 1991 review on tumor suppressor genes written at a time when understanding of how the genes work was limited. A recent major breakthrough in the understanding of the function of tumor suppressor genes is discussed. (LZ)

This paper discusses historical events responsible for public awareness of the theory of evolution. Particular attention is placed on the discovery of a coelacanth (a type of fish), since it may have the greatest significance in convincing the public of the reality of evolution. Discusses implications for the teaching of evolution. (LZ)

Provides a brief history, the science behind the art, and instructions for use of stereograms. (ZWH)

Describes the importance of eating properly. Presents two middle school level activities: the first activity has students record what they eat for nine days; the second activity includes listing the foods according to the food pyramid and discussing their decisions. Recommends three Web sites. (YDS)
