Table of Contents for Volume 15, 2007EMF HEALTH REPORT, Vol. 15, No. 6, November/December 2007Cell Phone Studies on the Periphery, by Robert B. Goldberg, Ph.D., editor, Information Ventures, Inc., Philadelphia, PAMost of the scientific community looks to large-scale, well-controlled studies, such as the INTERPHONE study, to evaluate possible risks of exposure from wireless technology. However, there is a segment of the scientific and activist community that distrusts indications of no consistent significant risk increases that have emerged from large epidemiologic and animal studies. Two recent publications illustrate the basis of that distrust and alternative approaches to assessing possible environmental and health impacts of the technology.

EMF HEALTH REPORT, Vol. 15, No. 5, September/October 2007Animal Models for EMF Research, by Robert B. Goldberg, Ph.D., editor, Information Ventures, Inc., Philadelphia, PAScientists use animals to study human diseases or effects of exposure to an agent such as EMF. The animal and the particular experimental set-up in these cases are referred to as animal models. In this article, Dr. Robert Goldberg discusses recent studies that provide examples of how animal models can be used to advantage in EMF research. One study looked at the possible effects of powerline exposure on dairy cattle. Two others looked at the effect of digital cell phone signals on blood circulation, blood-brain barrier function, and white blood cell adhesion in the brains of rats. The implications of the subtle effects seen in these animal model studies remain to be determined.

EMF HEALTH REPORT, Vol. 15, No. 4, July/August 2007Tumor-Treating-Field Device Enters Phase III Clinical Trials, by Robert B. Goldberg, Ph.D., editor, Information Ventures, Inc., Philadelphia, PAA new electromagnetic device used for treating recurrent brain tumors was developed by Yorum Palti, an M.D./Ph.D. and Professor of Physiology and Biophysics at the Technion-Israel Institute of Technology, in Haifa. Other EMF cancer therapies employ intense electric or magnetic fields to modify cell membranes or to heat tissues or ferromagnetic particles in tumor tissues. The approach developed by Palti uses very small electric currents and exploits a higher sensitivity to those currents in cells that are dividing. Dr. Robert Goldberg reviews cutting edge clinical research based on this technique.

EMF HEALTH REPORT, Vol. 15, No. 3, May/June 2007Accumulated Cell-Phone Results from the Interphone Study, by Robert B. Goldberg, Ph.D., editor, Information Ventures, Inc., Philadelphia, PAReports from research groups participating in the 14-country Interphone study of cellular (mobile) phone use and risk of brain tumors have continued to appear in the journal literature. We are still awaiting definitive cumulative assessments of all the data, but some preliminary patterns are emerging as studies from similar countries are pooled. While it may still take another year or two before definitive pooled study results appear in print, there are trends in the data indicating a low level of risk, but also some indications of greater risk with long-term phone use and an appreciation for the methodologic limitations of the studies that make this conclusion necessarily tentative.

EMF HEALTH REPORT, Vol. 15, No. 2, March/April 2007Negative EMF Studies, by Robert B. Goldberg, Ph.D., editor, Information Ventures, Inc., Philadelphia, PAStudies indicating no effects, or contradicting reported EMF bioeffects, so called “negative studies,” constitute a major portion of the EMF research literature. A major source of frustration for those trying to resolve EMF health effects issues, conflicting positive and negative reports seem to offer no definitive way to satisfy public concerns about the safety of EMF exposure. In this issue, Dr. Goldberg examines some of the attributes that define high quality negative studies, and discusses how negative results have shaped the debate on EMF hazards and influenced funding for EMF research.
EMF HEALTH REPORT, Vol. 15, No. 1, January/February 2007Biomagnetic Fields in the Brain, by Robert B. Goldberg, Ph.D., editor, Information Ventures, Inc., Philadelphia, PASome of the earliest experiments with bioelectricity came in areas that we would now consider neurophysiology and muscle physiology. These areas continue as a focus for potential new biomedical applications of EMF exposure. Four featured talks at the winter Bioelectromagnetics Society workshop (held in February in Washington, DC) on “magnetism in medicine” covered the use of magnetics for detecting brain currents and for manipulating electrical discharge in the brain to understand, and perhaps correct, abnormalities resulting from injury or mental disorders. Dr. Robert Goldberg reports on the workshop and reviews this latest neurology research that has built on basic bioelectromagnetics research, magnetic stimulation and recording, as well as molecular biology.
