This document provides a concise overview of current and historical interrelationships and patterns of national scientific and engineering resources. Major points of the report are: (1) research and development (R&D) expenditures in the U.S. are expected to reach $28.0 billion in 1972; (2) total R&D spending is estimated to rise 4.3% between 1971…

Research in photosynthesis is revealing a number of possible ways to increase the efficiency of carbon dioxide assimilation by crops and thus increase yields, a necessity in times of growing population and shrinking agricultural land. (Author/BB)

This article is designed to inform chemical educators not engaged in this technology as to the nature and methods used in the technology, the reasons for scientific and social concern, and the attempts made to assuage concerns involving recombinant DNA research. (author/BB)

The use of accelerators as mass spectrometers puts the work horse of isotope dating on a new, more useful footing. (Author/BB)

Electroencephalograms were analyzed during performance of verbal and spatial tasks. Complex scalp distributions of theta-, beta-, and, to a lesser extent, alpha-band spectral intensities discriminated between the two members of a pair of tasks, such as writing sentences and Koh's block design.

What shade of gray a surface appears is related to the perceived distribution of light and shadow, which in turn depends on the perceived spatial relation between the surface and its neighbors. (Author/ BB)

All-pass filter systems can be used in laboratory experiments in the physics and psychophysics of sound and music. Particular applications, such as lateralization of sounds in headphone listening, are presented. (BB)

Discusses the process of star formation. Infrared and radio astronomy, particularly microwave astronomy is used to provide information on different stages of stellar formation. The role of dust and gas which swirl through the interstellar regions of a galaxy and the collapse of a cloud in star formation are also presented. (HM)

Reviews recent developments in the study of an ultrafast process which utilizes short flashes of light. (SL)

Reviews recent developments in the field of laser fusion. (SL)

Discusses a summary of research pertaining to the Martian data from the Viking mission. This is a summary of some of the papers presented at the Lunar and Planetary Science Conference. (MR)

Discusses research into the influence of diet and various foods on human brain functioning. (SL)

SCOPE is an international group that studies the effects of human activities on the environment and serves as a source of advice on environmental problems. Presently, SCOPE is involved with seven major projects that include biogeochemical cycles, ecotoxicology, and environmental monitoring. The structure and components of SCOPE are also discussed.…

Surveys 5,000 years of artworks, encompassing 1,180 scorable instances of unimanual tool or weapon usage. No systematic trends in hand usage were revealed. Right hand use averaged 93 percent of all cases regardless of which historical era or geographic region was assessed. (SL)

Reports that the Research Applied to National Needs (RANN) program of the National Science Foundation (NSF) will be discontinued. (SL)
