Scientists exposed mealworm beetle pupae to 10 GHz microwave radiation and found that 76% either died or developed severe abnormalities, compared to 90% normal development in unexposed controls. When researchers heated pupae to the same temperatures using conventional heat, 80% developed normally, proving the damage was caused by the microwaves themselves, not just the heat they produced.
