Describes an experimental approach for controlling fusion that involves a toroidal device that holds and heats reactive isotopes of hydrogen with a magnetic field. (GS)

Describes an experiment in which Fresnel diffraction patterns were observed with a beam of slow neutrons of wavelength 4.33 Angstroms. (MLH)

Describes how the use of tunable lasers in coherent Raman techniques allows spectra to be taken for samples in which spontaneous Raman scattering is intrinsically weak. (MLH)

Discusses dichlorodiammineplatinum's ability to inhibit bacterial cell divisions and its use as an antitumor agent. (SL)

Discusses the renewed interest in superconductivity research and describes the differences between the two basic types of superconductivity. (MLH)

Discusses a new branch of optical spectroscopy that deals with the optical analogs of spin transients and provides ways to explore dynamic interactions in optically excited materials. (MLH)

Lists activities of the February 2-5, 1976, joint meeting of The American Physical Society (APS) and the American Association of Physics Teachers (AAPT) in New York city. (CP)

Discussed is the use and worth of any studies on animals in research. Topics included are human benefit, anthropomorphism, ecology, and the psychology of the use of animals in research. (DS)

Reviews creationist arguments attacking scientific evidence for evolution and an old earth, presenting counter-arguments from the evolutionist's point of view. (CS)

Outlines general principles in observing sharp electron spin resonance (ESR) lines in the solid state by incorporating the transition metal ion of interest into an isostructural diamagnetic host material in small concentration. Examples of some recent studies are described. (CS)

Considers a few areas of oxide/sulfide and intercalation-type chemistry. Discusses synthesis of the disulfides of the metals of group IVB, VB, and VIB; the intercalation reaction between lithium and titanium disulfide; other intercalates; and sulfide catalysts. (CS)

Presents an exact solution to the nonlinear Faraday's law problem of a rod sliding on frictionless rails with resistance. Compares the results with perturbation calculations based on the methods of Poisson and Pincare and of Kryloff and Bogoliuboff. (Author/GA)

Discusses new techniques for studying reactions that occur in the picosecond range and how the results of this research provide new insights into biochemical events and the chemical processes that take place in liquid systems. (MLH)

Discusses recent progress in using tunable lasers to selectively separate substances at the atomic and molecular level. Emphasizes biological applications, such as selective excitation and breaking of hydrogen bonds in DNA. (MLH)

Discusses new laser techniques that make it possible to see optical spectra without Doppler broadening, to label energy levels, and to enhance sensitivity. (MLH)
