Describes the procedure to test the hypothesis that subjects' brain waves in response to a television flicker (distraction) would be smaller in amplitude during television programs of high, in contrast to low, interest. Results from 12 viewers support the hypothesis. (CP)

Reports on scientific research with rats which has found that electrical stimulation in areas of the brain can trigger behavioral effects similar to those produced by narcotic drugs. (CP)

Describes the theory and application of an atomic fountain which pushes the atoms by laser pulses. Discusses the applications in measuring atomic properties and in building an atomic clock. (YP)

Discusses the Weinberg-Salam theory of the weak and electromagnetic interactions which is an attempt at a partially unified theory for physics. (HM)

Describes the features of various computer chemistry programs. Utilization of computer graphics, color, digital imaging, and other innovations are discussed in programs including those which aid in the identification of unknowns, predict whether chemical reactions are feasible, and predict the biological activity of xenobiotic compounds.
