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)

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)

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)

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

Describes the use of free-electron lasers as a source of coherent radiation over a broad range of wavelengths from the far-infrared to the far-ultraviolet regions of the spectrum. Discusses some applications of these lasers, including medicine and strategic defense. (TW)

The Gordon Research Conferences were established to stimulate research in universities, research foundations, and industrial laboratories. The topics for the conferences are listed as well as the locations and scheduled presentations at each conference. (CS)

Discussed are past work and recent advances in the use of electron microscopes for viewing structures immersed in gas and liquid. Improved environmental chambers make it possible to examine wet specimens easily. (Author/RH)

Included is a list of laboratory instruments and equipment and the names and addresses of their manufacturers. Names of instruments appear in alphabetical order in heavy black type and the names of manufacturers of each instrument appear below each instrument entry in ordinary type. Each instrument is identified by a "category number." Unnumbered…

Illustrates the state of the art in pyrolysis mass spectrometry techniques through applications in: (1) structural determination and quality control of synthetic polymers; (2) quantitative analysis of polymer mixtures; (3) classification and structural characterization of fossil organic matter; and (4) nonsupervised numerical extraction of…

Investigates Mercury concentration in ocean water in the Gulf Stream. A correlation was found between variations in mercury and silicate, suggesting a common link in their marine geochemistry. (HM)

Discusses recent developments in the instrumentation and practice of analytical scale operations. Emphasizes detection devices and procedures in gas chromatography, liquid chromatography, electrophoresis, supercritical fluid chromatography, and field-flow fractionation. (JN)

Summarizes some recent scientific achievements in particle physics, bioinorganic chemistry, geology, and the life sciences. Discusses research as it applies to the needs of society, including areas of concern for the future. Describes the role of the National Science Foundation as supporting research and education in the sciences and engineering.…
