Describes how a behavioral system in Aplysia (marine snail) can be used to examine mechanisms of several forms of learning at different levels of analysis: behavioral, cell-physiological, ultrastructural, and molecular. Focusing on short-term sensitization, suggests how molecular mechanisms can be extended to explain long-term memory and classical…

Discusses the high school framework and standards developed by the National Science Teachers Association in the subjects of physics, chemistry, biology, and earth and space sciences. (MKR)

Advances in the genetics and cell biology of muscle development are discussed. In-vitro analysis of the renaturation, polymerization, and three-dimensional structure of the purified proteins involved is described. (CW)

Makes the case that the traditional sequence of biology, chemistry, and physics in U.S. high schools may be at the root of poor student performance. Reviews integrated, inverted, and coordinated science teaching. (DDR)

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)

Discusses insights discovered from research into human biology that are raising possibilities for therapy, prevention of disease, and challenges to society in the form of ethical decisions about the appropriate application of genetic information. (Author/RT)

Expresses concern over recent actions by coalitions of neighborhood activists and animal rightists in the San Francisco area that are seeking to block new biology laboratories. Argues that costly delays and disurption of research could result. (TW)

This article describes the history of the molecular revolution in biology and emphasizes its dependence on the emergence of bacterial genetics, the fusion of genetics and biochemistry, and the development of new techniques for studying macromolecules. (Author/SA)

Summarizes the history of the conflict between evolutionists'' and creationists'' concerning the content of biology textbooks based on the Science Framework for California Public Schools, and discusses the positions that have to be resolved by the California Board of Education. (AL)

Describes the diversity of plants. Outlines novel developmental and complex genetic processes that are specific to plants. Identifies approaches that can be used to solve problems in plant biology. Cites the advantages of using higher plants for experimental systems. (RT)

Outlines the main features and areas of responsibility of an international, non-governmental body proposed by the Council for International Organizations of Medical Sciences to explore the moral and social issues raised by recent and impending developments in biology and medicine. (AL)

Discussed are some of the strategies required to try to detect and explain DNA markers that account for small amounts of behavioral variation. Situations in both animal and human behavior are described. The link between molecular biology and behavior is highlighted. (CW)

Discussed is the movement against the use of dissections in science laboratories. Examples of protests across the United States are included. Compared is the plight of using animals in a biology classroom and the demise of the teaching of evolution in some areas. (KR)

Cites changes to occur on the Medical College Admissions Test to include: a reduction from six to four sections, biology and physics content-specific sections to absorb chemistry, elimination of multiple-choice questions to a problem-solving format, and the inclusion of graded essay questions. (RT)
