Events related to the reported isolation and identification of scotophobin, a dark-avoidance-inducing substance, have provided an example of the often-obscured aspect of the scientific process of criticism and doubt which can only be removed by scrutiny and duplication of experimental results in other laboratories (CP)

Discusses the Senate's passage of a bill setting up a Civil Science Systems Administration to initiate and direct research and to assist in transition of scientists and engineers to civilian oriented programs. Another bill which provides for a 10-year voluntary transition to the metric system passed. (CP)

Scientist William J. Dreyer has hypothesized that the cell surface proteins in the nose that detect odors also help assemble embryos. These olfactory receptors and related proteins act as identifiers, much like the last few digits of a telephone number, that help cells to find their intended neighbors in a developing embryo. Discusses the research…

The hazards posed by new techniques of genetic manipulation have prompted scientists to regulate and in some cases restrict their own basic investigations. Describes some possible applications of the new techniques and outlines the established research guidelines. (GS)

The effect that pesticides can have on natural ecosystems is discussed. Specific examples are drawn from microbial ecosystems in estuarine regions. (DT)

Status reports on broad areas of Government-funded health research and research policy are briefly reviewed. (DT)

Describes the physical aspects of Mars, including old and new theories. Discusses the proposed landing sites of Viking. (MLH)

A history of what anatomists thought about the brain from the ancient Egyptians and Greeks up to the turn of the present century. (BB)

A brief discussion of neurophysiology, neurotransmitters, and the effect of psychoactive drugs on brain diseases such as schizophrenia. (BB)

Some newly reported research results indicate that slightly abnormal biological rhythms, both long- and short-term, may be key factors in the development of depression and manic-depression. The results may also hold clues about why certain drugs work or fail to work with different individuals. (Author/BB)

This article discusses the science and politics of IQ. It discusses the research that has been completed on both the environmental and heredital aspects of intelligence and the effect the answers to this question can have on educational policy. (BB)

Describes two studies of brain hemisphere development which indicate children retarded in the functions of one hemisphere may not be retarded in the functions of the second hemisphere. Suggests that the left hemisphere functions may inhibit some right hemisphere functions. (SL)

Highlights activities and scientific accomplishments at the Medical Research Council Laboratory of Molecular Biology in Cambridge, England. Includes comments by staff scientists about their current research endeavors. (JN)

Discusses various theories about life on Mars and biochemical experiments pertaining to the origin of life. (MLH)

Describes recommended Department of Health, Education, and Welfare (HEW) regulations concerning the participation of institutionalized persons in behavioral research. (SL)
