R. A. MOIDEL, S. K. WOLFSON, JR., R. G. SELKER, S. B. WEINER · 1976
Researchers in 1976 studied implanting metallic materials like carbon steel rods into brain tissue, then exposing the head to radiofrequency electromagnetic fields to create localized heating. They found that carbon steel and Hysterlo materials heated most effectively (up to 655 cal/g-min) when oriented parallel to the RF field. The goal was to combine targeted brain heating with chemotherapy to concentrate cancer drugs in tumors while keeping healthy tissue cool.
Gideon Kantor, Thomas C. Cetas · 1976
This 1976 study tested how different microwave diathermy devices operating at 2.45 GHz heat tissue phantoms simulating fat and muscle. Researchers found that properly designed direct-contact applicators could maintain radiation leakage below 5 mW/cm² at 5 cm distance while delivering therapeutic heating. The study established safety standards for medical microwave devices that are still used in physical therapy today.
U. Zimmermann, G. Pilwat, F. Beckers, F. Riemann · 1976
Researchers applied electrical fields to giant algae cells and discovered that cell membranes undergo dramatic breakdown when exposed to approximately 1 volt of electrical potential. The membrane conductance increased dramatically at 0.85 volts, demonstrating that cell membranes have a specific electrical threshold where they lose their protective barrier function.
Arthur W. Guy, Michael D. Webb, Carrol C. Sorensen · 1976
Researchers used thermographic measurements on scale models to determine how much radiofrequency energy the human body absorbs when exposed to high frequency electromagnetic fields. They found that exposure to 31 MHz radiation at 10 mW/cm² could produce peak absorption rates as high as 5.63 W/kg in humans. The study confirmed that power absorption increases with the square of frequency below 31 MHz.
S. Georghiou · 1976
This 1976 study examined how light causes rapid structural changes in all-trans-retinal, a key molecule in human vision, at low temperatures. Researchers found that retinal exhibits unusual optical properties including wavelength-dependent fluorescence and anomalous heavy atom effects. The findings help explain the early stages of how our eyes convert light into visual signals.
R. SUNDERMAN, T. Z. FAHIDY · 1976
This 1976 research by Sunderman investigated how alternating electric and magnetic fields create movement in electrolyte solutions (liquids containing dissolved salts and ions). The study examined the mechanisms behind field-induced fluid motion, which is fundamental to understanding how electromagnetic fields interact with biological fluids in living organisms.

The research addressed safety concerns about therapeutic microwave use and device malfunctions in medical settings.
James C. Lin · 1976
This 1976 study examined why people hear sounds when exposed to pulsed microwave radiation, a phenomenon known as the microwave auditory effect. Researchers compared three possible mechanisms and found that thermal expansion (rapid heating and cooling) in the head likely creates the perceived sounds. The study helps explain how microwave energy can directly stimulate auditory sensations without sound waves.
Lin JC, Wu C-L · 1976
This 1976 study analyzed how plastic restraining devices used to hold laboratory animals during microwave experiments scatter and amplify microwave radiation. Researchers found that these supposedly "low-loss" materials created highly uneven radiation patterns, with some areas receiving nearly twice the intended exposure levels.
Peter Atkins · 1976
This 1976 technical review by Peter Atkins examined the scientific literature on magnetic field effects on chemical reactions. The author noted that the field was plagued by unreliable research and charlatans, but identified a body of modern literature that appeared scientifically credible. The review aimed to separate legitimate magnetic field research from fraudulent claims.

James L. Mason, Neilson A. M. MacKay · 1976
Researchers investigated why electrical stimulation through the skin often causes sharp, pricking pain. They discovered the pain results from thermal damage to the skin's outer layer caused by high energy concentrations at uneven skin-electrode contact points. The study found this pain can be controlled through proper electrode application techniques without using conductive gels.
Vernon L. Newhouse, Phillip J. Bendick, L. William Varner · 1976
This 1976 technical study analyzed how signal timing affects Doppler flow measurement systems used in medical diagnostics. Researchers found that random signal Doppler systems produce the same output as pulsed RF Doppler systems when properly calibrated. The work focused on improving medical ultrasound and flow measurement technology rather than health effects.
Claire A. Van Ummersen, Frances C. Cogan · 1976
Scientists exposed rabbit eyes to 2.45 GHz microwave radiation (the same frequency used in microwave ovens and WiFi) at levels known to cause cataracts. They found the radiation disrupted normal cell division in the eye lens, either suppressing it initially or causing abnormal increases later, depending on the severity of lens damage.
Charles E. Tinney, James L. Lords, Carl H. Durney · 1976
Researchers exposed isolated turtle hearts to 960 MHz microwave radiation and found it caused the heart rate to slow down (bradycardia) at specific power levels between 2-10 mW/g. This effect appeared to work through nerve pathways rather than simple heating, since higher power levels that caused heating actually increased heart rate instead.
J. Eugene Robinson, Duncan McCulloch, Edgar A. Edelsack · 1976
Researchers used 2450 MHz microwaves (the same frequency as microwave ovens) to heat tumors in mice, finding that 200 watts was barely enough to warm small tumors. They developed a technique combining warm air with microwaves to achieve therapeutic heating levels more efficiently and uniformly.
