Researchers compared 39-MHz and 2450-MHz radiofrequency electric fields for killing adult rice weevils in hard red winter wheat. Complete mortality was reached at 39 MHz with grain temperatures of about 40°C, whereas 2450 MHz needed about 80°C. Insects surviving 39-MHz exposure showed severe injury and high delayed mortality, while those surviving 2450-MHz exposure moved normally. Progeny emergence was nearly eliminated at 39 MHz above 50°C but persisted across most 2450-MHz treatments.

Water bath warming to 97±1°F did not alter electrolyte or enzyme levels in banked blood. The microwave warmer caused hemolysis in 35% to 40% of blood samples warmed.

The analysis focused on detecting excessive fluid accumulation in interstitial lung regions, not on identifying diseased lung tissue itself. Prior attempts to distinguish normal from abnormal cells by microwave methods at the University of Pennsylvania and in the USSR yielded negative results because electrical properties are not sufficiently different. The author noted that wavelength must be smaller than the area being mapped, so centimetric waves suit decimetric lung cavities.

Uniform cholinesterase inactivation was achieved in rat brain within 4 s and in mouse brain within 2 s. In rats, whole-brain acetylcholine was 25-4 + 1-5 nmol/g after irradiation compared to 13:8 + 1-7 nmol/g after standard sacrifice. In mice, whole-brain acetylcholine was 25:5 + 2:6 nmol/g after irradiation compared to 13-7 + 1:7 nmol/g after standard sacrifice.

The paper introduces a semiclassical theory that treats the electromagnetic field classically and the membrane dipoles quantum mechanically using the density matrix approach. The model assumes a double-dipole layer membrane where nerve excitation occurs when enough outer dipoles flip orientation to reduce the potential barrier.

Researchers exposed roots of Lepidium sativum, coleoptiles of Avena sativa, and sporangiophores of Phycomyces blakesleeanus to an intense magnetic gradient while rotating them on a slow klinostat at 0-5 rpm. All three species showed a growth curvature away from the magnet gap, down the magnetic gradient toward lower flux density, after an initial lag period. The reciprocal of the reaction time was the best measure of response and correlated with magnetic field parameters: for Avena and Phycomyces with log dH/dx and log H·dH/dx, and for Lepidium with log H. Only Stage I sporangiophores of Phycomyces responded to the magnetic gradient, while later stages showed no consistent curvature.
