Reports an experiment for examining protein-ligand binding using the enzyme carbonic anhydrase. Describes the experimental procedures consisting of the syntheses of an azosulfonamide and its complex formation with carbonic anhydrase. (YP)

Discusses a National Academy of Science forum at which a group of outstanding young researchers in astronomy, molecular and developmental biology, physics, chemistry, mathematics, atmospheric science, and materials science met for three days of formal presentations and informal conversations. Provides a short synopsis of major speakers. (MVL)

Describes ways to use nomographs, including solving equations for equivalent resistance of a parallel circuit, focal length of a thin lens, parallel combinations of standard resistance, average speed, refraction problem, and height of a vertically projected object. (YP)

Describes the astrocytes' function as equal partners with neurons in both the normal and the abnormal brain. Discusses the developmental scaffolds, inert scar tissue, Huntington's disease, psychiatric disorders, and the identification of these brain cells. (RT)

Described is a simple demonstration of fermentation. The materials needed, the basic experimental set-up, and various projects are outlined. Included are a diagram of an apparatus for measuring carbon dioxide production and a table showing typical results of the effect of pH on fermentation. (RT)

Students write a short paper in which they describe and interpret the history of a geologic feature. Provides an introduction, logistics of the assignment, background and rationale for the writing process, suggestions for change, and conclusions. (RT)

Described is a tilting cage used to record the activity of a mouse over a 24 hour period. The construction of the apparatus, methods used and data analysis are discussed. Follow-up class activities are suggested. (CW)

Describes a demonstration of Coriolis acceleration. Discusses two different meanings of "Coriolis" and two causes of Coriolis acceleration. Gives a set-up method of the demonstration apparatus by using a rotary disk with rubber tubing for tap water, switches, lamps, battery, and counterweight. Provides two pictures with operating method.…

Describes an experiment for determining the refractive index. Discusses the experiment procedure and mathematical expression for calculating the index. Provides two geometrical diagrams and a graph for determining the index with a typical data. (YP)

Cites results of an engineering and engineering technology faculty survey. Provides charts and tables which can be used to establish baseline information and identify trends that are useful in diagnostics and planning. Includes survey response rates. (RT)

Describes composite materials and related industries. Discusses the few courses at the undergraduate level, the few schools offering the courses, alternatives to these courses, job opportunities, and future trends. (YP)

Discusses what technology assessment can gain from historical knowledge and historical perspectives. Investigates points of intersection starting from a consideration of the general aims. Outlines some ways in which historical research can contribute to the theoretical foundations of technology assessment and to the process of reaching judgments.…

Examines the procedural and philosophical perspectives taken by science in examining human characteristics. Discusses the different levels of accuracy of various scientific fields. Encourages discussion of what biological and behavioral sciences can and cannot reveal about complex human nature. Considers some characteristics of quality science…

Argues that advances in Earth science call for their inclusion in Earth history. States that the focus should be on the planet and the process by which it reached its present state. Explains pre-solar and pre-lithospheric history, interacting spheres of influence, characteristics of eons and eras, and their transitions. (RT)

Discusses the vestibulo-ocular reflex (VOR) which is used to investigate the neural basis for motor learning in monkeys. Suggests organizing principles that may apply in forms of motor learning as a result of similarities among VOR and other motor systems. (Author/RT)
