Researchers exposed isolated rat eye lenses to different temperatures to determine whether microwave-induced cataracts result from electromagnetic radiation or simple heating. They found that moderate temperature increases (39-41°C for one hour) caused cataracts similar to those seen in microwave studies, while very high temperatures (60-65°C) actually preserved lens clarity through a 'fixing' process.

Researchers used mathematical models to calculate how electromagnetic radiation penetrates and deposits energy in human heads, comparing adult and infant absorption patterns. They tested different head shapes (spheres, prolate spheroids, and ellipsoids) and found ellipsoidal models most accurately predicted power absorption. The study revealed that infants may absorb electromagnetic energy differently than adults due to their smaller head size.

Researchers exposed cancer cells to 30 MHz radio frequency fields in laboratory conditions, then implanted them into specially selected mice to detect subtle biological effects. They found that RF-exposed cancer cells were more likely to regress (shrink and disappear) after implantation, leading to higher survival rates in the host mice. This innovative approach revealed biological effects that were too subtle to detect through direct cell observation alone.
