Assesses dimensions of the threatened-species problem (by contrast with the way it has been handled in the past) and suggests some directions for urgent research if the problem is to be confronted in its proper scope and scale. Among topics addressed are the biological, genetic, and ecological attributes of species. (JN)

Annotates two books dealing with astronomy and one each dealing with automation, genetic engineering, space, and water. (AEA)

Two anthropologists report on their investigation of sudden nocturnal deaths among Southeast Asian male refugees in the United States. They suggest that such deaths are attributable to a combination of genetically transmitted, physiological problems, cultural/religious beliefs, and psychological stress. (GC)

The column briefly reviews current research and thinking on such topics as a genetic basis for LD (learning disabilities), sleep electroencephalography patterns of hyperactive children, psychological traits of parents of LD children, early intervention for LD students, and external locus of control in LD schools.

Sources of misconceptions and learning difficulties were identified by interviewing academically sound A-level students (N=10) who were having difficulties with genetics. Indicates misconceptions were related to nature of concepts used in genetics, such as frequent representation of meiosis by fixed inanimate stage diagrams and to instructional…

Describes an imaginary organism used to illustrate principles of genetics. The organism is easily drawn and suited to simple printing techniques, having been used to show independent segregation, partial dominance, linkage (sex chromosomes and autosomes), and in inheritance of autosomal gene lethal in the homozygous state. Additional exercises are…

A review of studies on mental retardation published in the Soviet Union between 1970 and 1980 touches on physical and neurological issues, genetic studies, learning and memory, and emotional factors. General conclusions drawn include that more males are retarded or emotionally disturbed than females. (CL)

Summarizes Arthur Jensen's theories on IQ, heritability, and Black intelligence and reviews some responses to Jensen. (JLF)

Presents some techniques developed to help improve student understanding of Mendelian principles through the use of a computer simulation model by the genetic system of the fruit fly. Includes discussion and evaluation of this computer assisted program. (MA)

Huntington's disease is an autosomal dominantly inherited disorder. No definitive method for the preclinical detection of carriers is known. The consequences of this diagnosis are discussed. The significance of genetic counseling and a description of the phases in psychological coping is presented to enable informed decision making by family…
