Hardly any phenomenon in the modern environment is as ubiquitous as electromagnetic fields and waves. We have learned to understand the physical characteristics of these energy forms, and we have applied them in abundant ways to embellish our ways of life and our standards of living. Furthermore, we have come to depend on them for health, safety, information, comfOli, and conveyance. Apart from their intended roles, these electromagnetic fields and waves produce other effects which may influence the activities of living organisms. The effects produced depend on many physical, chemical, and biological factors. They may be grossly apparent and visible soon after exposure of the living organism or they may not appear to have influenced the organism at all upon casual examination. Even then, there may be subtle changes which are only detectable upon careful chemical or microscopic study, or which are apparent only after a considerable time delay. Nevertheless, our understanding of the interaction of electromagnetic fields with living systems is advancing in a wide range of topical areas. This bi-annual series with invited reviews by recognized leaders in their respective specialties, will present progress to date in key areas of research and scholarship. The guiding philosophy of this undertaking is the presentation of integrated, known, and confilmed phenomenological observations, basic mechanism of interactions, and applications in biology and medicine, as well as perspectives on current topics of interest.
