The directory lists medical genetic units in the United States and elsewhere in the world. The director and address of each unit are specified; types of genetic services available are indicated by code. (JD)

This booklet, in the series "Understanding the Atom," summarizes the important findings on radioactive fallout for which there is substantial scientific agreement, indicates the areas of disagreement, and lists some answered questions. Sources of fallout, its local and worldwide effects (including movement in the atmosphers), the…

Describes the science of hair analysis and its use in the solution of crimes. Methods of analysis and genetic and environmental characteristics which can be inferred are presented. (CP)

Stresses ways to answer questions related to widespread publicity - are nuclear reactors safe, will dangerous research in genetic manipulation be banned? - with emphasis on true meaning of safety as related to risks. (EB)

Describes the Miller and Urey experiment to synthesize organic compounds. Includes subsequent research and relates these studies to the formation of one-celled organisms in an oxygen-free atmosphere. (MA)

Discusses private interest attacks on academic freedom and the underlying question, "what kinds of scientific research are to be screened by public debate"? Suggests that it is the implications of research that should receive public and ideological attention while the research itself should be evaluated by objective scientists, those…

The application of component analysis to phenotypic, genetic, and environmental correlation matrices is discussed. Formulas for computation of component scores and the interpretation of factors is discussed. An example is presented. (Author/JKS)

The author, a physicist, chemist, and geologist, describes the new frontiers of scientific research. (Editor/RK)

Presents an essay review of three recent books on eugenics, a once popular quasiscientific and politically conservative social movement devoted to the improvement of humankind through programs of selective breeding and marriage restriction. States that educators must study and come to grips with the meaning of this movement in order to appreciate…

A study compared intelligence scores of three groups of Israeli deaf children--23 with deaf parents/deaf siblings and manual communication (DpDs), 76 with hearing parents/deaf siblings, and 144 with hearing parents and siblings. The DpDs children were superior to other deaf children and comparable to hearing children on most intelligence measures.…

The goals of this review are to: (1) provide a set of concepts to aid in the understanding of complex processes which occur during central nervous system (CNS) development; (2) illustrate how they contribute to our knowlege of adult brain anatomy; and (3) delineate how modifications of normal developmental processes may affect the structure and…

Discusses how genetic data on present human population relationships and data from the Pleistocene fossil hominid record are being used to compare two contrasting models for the origin of modern humans. (TW)

A review of current literature suggests that many cases of autism may well have both environmental and genetic etiologies and that more than one genetic locus is likely. Some evidence suggests that some genetic abnormality of language or sociability is inherited which then interacts with other factors to produce autism. (DB)
