This article calls for a more intimate relation between industry and academia. It discusses the essential features of the U.S. research and development system, looking at characteristics of industrial research and of academic research as they might affect a partnership. (author/BB)

Details of the landscape of the planet Venus as revealed by the Magellan spacecraft are discussed and illustrated. Advances beyond previous space probes are demonstrated. Details of the program are described. Additional work from this project is proposed. (CW)

Discussed is the discovery which may help to explain epidermal growth factor effects on the cell skeleton. The role of a protein called profilin in the regulation of the microfilament system is described. (CW)

Presents a hypothesis about the biochemical processes involved in memory storage. The postulated mechanism is initiated by a signal that is unusual but not unlikely to occur and produces an irreversible change in a key component of synaptic chemistry. Other features of the mechanism and experiments supporting the hypothesis are considered. (JN)

It has recently been shown that perceived motion, in the absence of any appropriate retinal motion, is a sufficient stimulus to generate smooth pursuit eye motions. However, three experiments show that perceived motion is not necessary for pursuit, but that retinal motion always governs pursuit. (BB)

This letter is polemic. It has been proposed that developmental dyslexia is associated with bilateral hemispheric representation of spatial function that interferes with specialized left hemispheric processing of linguistic information. The data presented, however, may not warrant this conclusion. (BB)

Advances in the genetics and cell biology of muscle development are discussed. In-vitro analysis of the renaturation, polymerization, and three-dimensional structure of the purified proteins involved is described. (CW)

The demographics of academic science are changing with the increase in the number of doctoral level researchers who are excluded from the traditional faculty tenure track, but hold research posts on open-ended terms. (Author/BB)

Discussed are the behaviors of particles and energies in the magnetic fields of neutron stars. Different types of possible research using neutron stars as a laboratory for the study of strong magnetic fields are proposed. (CW)

Summarizes events of a conference on evolutionary biology in Chicago entitled: "Macroevolution." Reviews the theory of modern synthesis, a term used to explain Darwinism in terms of population biology and genetics. Issues presented at the conference are discussed in detail. (CS)

Describes the subdivisions of the human peri-Sylvian language cortex which were determined by stimulation mapping during craniotomies of four adult patients. (SA)

Presented is experimental evidence that humans develop strong preferences for objects that become familiar through repeated exposure, even when the exposures are so degraded that they cannot be discriminated as stimuli previously seen. Implications are made regarding other studies where affective discriminations are made with very little stimulus…

Data are presented from families of monozygotic twin pairs which give evidence of genetic variance on the Block Design Test, a nonverbal measure of intelligence. Analyses of genetic and environmental effects on behavior are possible with this kind of information. (SA)

Discusses trends that have converged to transform our understanding of genetic and environmental influences on personality traits. Presents five main determinants of personality. (ZWH)

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.
