Argues against Hillman and Sartory's views of cell structure (EJ242880), pointing out that they are erroneous in their analysis of the motives and working methods of the scientific community, in their total rejection of information coming from electron microscopy, and in their claim that lysosomes and endoplasmic reticulum are imaginary.

Three major breakthroughs in Antarctic earth sciences which occurred during 1982 are discussed (finding of land fossils, meteorite, and subsurface microorganisms). Highlights of conferences, research activities, and significant publications are also discussed. (JN)

Discusses unpaid postdoctoral researchers, especially those in biology and medicine, addressing reasons why they work without pay, how they receive funding, efforts to help them, their impacts on the field, and personal concerns. (DC)

Describes the use of James Watson's book, "The Double Helix," as a multidisciplinary way of introducing students to actual science; the scientific method; dilemmas encountered in the world of research; and the rich setting of personalities, politics, and history in post-World War II Europe. (MKR)

Thirteen articles in this special issue discuss aging theories, biomarkers of aging, aging research, disease, cancer biology, Alzheimer's disease, stress, oxidation of proteins, gene therapy, service delivery, biogerontology, and ethics and aging research. (SK)

Describes the history of the study of dinosaurs and current topics of research in the field. Contains 18 references. (WRM)

This guide provides summaries of federal programs in the biological sciences of interest to colleges and universities. Programs described fall within the following agencies: National Science Foundation, Public Health Service, Smithsonian Institution, Department of State, Department of Agriculture, Department of Commerce, Office of Education,…

After summarizing the development of ecology from botanical and zoological studies to a study of entire biological communities, the history of wool growing in England and the development of nomadism on the Asian steppes and the North American prairies is described. These examples are interpreted ecologically and used to illustrate the theses that…

Although the Ceylonese Education Department based its revision of school science curricula on a 1963 UNESCO report, little use has been made of members of the universities. This has resulted in courses containing much confusion and absurdity, at least in biology. An alternative biology project was established by the Ceylon Association for the…

Two specialized facilities to produce cells and cell components on a large scale for scientific research have recently been established by the National Science Foundation. (BB)

Through the use of learned symbols, two chimpanzees accurately specified 11 foods by name to one another when the food item's identity was known by only one and requested specific food of one another by name. Requests resulted in cooperative and reciprocal symbolically mediated food exchange. (Author/MA)

Actin and myosin have now been demonstrated to be important constituents of many eukaryotic cells. Their role is primarily that of a contractile system underlying all aspects of cellular motility. Described here is a simple experimental system to demonstrate quantitatively aspects of motility and its regulation in a slime mold. (Author/MA)

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…

Discussed is the tendency in science to challenge obvious explanation for observed phenomenon. Ten examples are given where the initial obvious explanation was subsequently shown to be totally incorrect. Four examples that relate to biomedicine are presented in detail. (SL)
