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…

Provides information on updating older fume hoods. Areas addressed include: (1) adjustment of the hood's back baffle; (2) hood air leakage; (3) light level; (4) hood location in relation to room traffic and room air; and (5) establishing and maintaining hood performance. (JN)

Recognizing that success in general chemistry is dependent on the development of disciplined study habits, the author motivates his students to develop these skills through prelecture assignments that introduce them to various studying strategies. The format and use of the prelecture assignments are described. (JN)

Describes two quantitatively-oriented physiology laboratories for veterinary students. The laboratory exercises incorporate the procedures of radiology and physical examination with measurement of pulmonary function. Specific laboratory objectives, procedures and equipment needed for diagnoses of the pathologies are listed. (ML)

Presents American Chemical Society statistics on bachelor's, master's, and doctoral graduates from approved schools from 1980-84. Comparisons are made for yearly growth, certified/noncertified graduates, and men/women for both chemistry and chemical engineering. Also lists numbers and types of chemistry/chemical engineering degrees awarded by each…

Chemical reaction rates can be controlled by varying composition of miniscule clusters of metal atoms. These bimetallic catalysts have had major impact on petroleum refining, where work has involved heterogeneous catalysis (reacting molecules in a phase separate from catalyst.) Experimentation involving hydrocarbon reactions, catalytic…

Encouraging a science park at Cambridge University has resulted in a geographically compact community with a broad range of high-technology industries. Factors leading to this university/business success (also called "The Cambridge Phenomenon") include: more relaxed attitudes about faculty's outside activities; positive attitudes toward…

Developmental stages of the beech weevil ("Rhynchaenus fagi") are suggested for experiments on population dynamics. Explains the weevil's life history, illustrating convenience of immature stages for study of development and mortality. Limitations of the study as well as possibilities for changing its emphasis are also discussed. (Author/DH)

Describes and lists a program for Apple Pascal Version 1.1 which investigates the behavior of the bicarbonate-carbon dioxide buffer system in acid-base disorders. Designed specifically for the preclinical medical student, the program has proven easy to use and enables students to use blood gas parameters to arrive at diagnoses. (DH)

Characteristics of science are explained through a historical and a functional approach. Indicates that science works successfully toward traditional goals because individual and group goals tend to coincide, and that competition between individual scientists contributes to the functional organization of science. (DH)

The belief that "knowledge is most effectively pursued when disseminated without hindrance" began when science first took shape in early Greece. Its development during the Middle Ages and Renaissance is discussed (examining patenting innovation), ownership rights became more important as science became a means to power. (DH)

Describes the use of an inexpensive apparatus (based on a butane lighter fluid can and a standard tire pressure gauge) in measuring the atomic/molecular mass of an unknown gas and in demonstrating the mass of air or the dependence of pressure on the mass of a gas. (JN)

Determined which form of kinetic structure (high or low) and/or micrograph content (unified or varied) was most effective on introductory college biology students' (N=100) achievement of reading micrograph skills. Findings, among others, suggest that high kinetic structure instruction does not affect actual reading micrograph skills, but…

Suggesting that descriptive chemistry is basic to basic chemical literacy, offers examples of descriptive chemistry problems (with answers) based on inexpensive, short, safe, striking, and simple lecture experiments. Issues related to the teaching of descriptive chemistry are also addressed. (JN)

Several interesting and important examples of kinetic stability and kinetic control in organic systems are discussed. Audiovisual aids, lecture demonstrations, and laboratory activities that can be used to convey the material in a clear and stimulating fashion are also described. (JN)
