Researchers demonstrated that radar transmitters operating at 1, 3, and 10 gigahertz can be directly heard by the human brain, bypassing the ears entirely. The effect occurred at energy levels considered safe for all-day exposure, suggesting the brain itself can detect electromagnetic radiation. This phenomenon may explain reports of people hearing meteors and aurora displays.

Military researchers studied how high-intensity thermal radiation affects human pain perception and tissue damage across different body areas. The study examined how the size and location of exposed body areas influence pain response, using pain as an indicator of tissue damage. This research aimed to understand thermal radiation effects on military personnel exposed to flames and special weapons.

Researchers exposed rats and mice to powerful 60 Hz electric fields (100 kV/m) for up to 4 months, measuring growth rates, organ weights, metabolism, and hormone levels. Despite using carefully controlled conditions to eliminate interference factors, they found no significant differences between exposed and control animals in any measured parameter. This challenges previous conflicting studies that reported both enhanced and reduced growth from electric field exposure.
