The neural networks of several invertebrate animals are currently being studied for clues to cerebral function. The major goal of the studies is an understanding of the neural mechanisms behind learning. Organisms used, examples of research studies, and implications are discussed. (Author/JN)

The biological research, of Gottfried Schatz at the University of Basel and Gunter Blobel at Rockefeller University, which explains a mechanism by which mitochondrial proteins are transported across membranes is described. Results indicate that the construction and heredity of mitochondria have surprising differences from other cell processes. (BT)

Describes a DNA profile technique that was performed by a group of high school juniors and seniors. (JRH)

Describes the history of comparative methods and their use in biology as an investigative philosophy. Discusses Bernard's and Krogh's ideas and supports Jorgensen's arguments. Explains conceptual change in the comparative studies which is referred to as "comparative phylogenetic method". (Contains 33 references.) (YDS)

Discusses recently published work that appears to have many of the answers to the question of how the nervous system develops. Focuses on the discovery of what is believed to be neural inducer, a protein called noggin. (LZ)

The Soil Biotron at the University of Michigan is a unique underground laboratory designed for study of the forest ecosystem, including both soil invertebrates and plant life. It is used for observation and experimentation and allows study over a period of decades rather than seasons. (MSE)

This paper describes the results of a questionnaire survey of UK Year 3 biology undergraduates' career aspirations, and their perceptions of employment in teaching, research and conservation. Although most students sought material benefits in their potential careers, even more wished to gain job satisfaction. None of the careers in biology was…

According to Carl Sagan (1987), "Science is a way of thinking much more than it is a body of knowledge." Field studies and undergraduate research provide students with the best opportunities for "thinking" about science, while at the same time acquiring a body of knowledge. Natural History of Tropical Carbonate Ecosystems is a…

Virology is an integral part of introductory biology courses. Research and experience indicate that, although the topic is a difficult one for many students, the effectiveness of instruction is enhanced when assignments actively engage the students in the generation of scientific explanations. These authors have found that the methods and…

Peer-reviewed literature is the single most important forum in which research findings are presented for critical review. College biology students can benefit a great deal from early exposure to this resource, but insufficient background information, technical jargon, and complex statistical analyses often present considerable obstacles to…

Reported are the proceedings of an interdisciplinary symposium on the effects on the biosphere of the release of radiation from the use of nuclear energy. Papers given include discussions of the use of radioisotopes in medicine, the benefits and possible consequences of peaceful applications of nuclear explosives, methods of estimating maximum…

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…

Reviews possible biochemical markers for suicide risk but notes that none has clear application for clinical work in suicide prevention. Comments on other biological aspects of suicide including genetics, plasma drug levels, electroconvulsive therapy (ECT) and psychoimmunology. Encourages ECT use. Cautions against hasty clinical use of other…

Reports on recent research into the operation of neuronal local circuits in higher brain functions. (CP)

If the aim of new research is to improve the genetic inheritance of future generations, then decisions regarding who should decide what research should be done needs to be established. Positive and negative eugenics need to be considered thoroughly. (PS)
