An Evaluation of Neuronal PARP-1 and Caspase-3 Levels in the Brain Tissue of Female Rats Exposed to Electromagnetic Fields at Different Gestational Stages

Unknown authors · 2025

Researchers exposed pregnant rats to 900 MHz EMF radiation (similar to cell phone frequencies) during different stages of pregnancy and examined brain damage in their offspring 28 days after birth. They found that exposure during the final week of pregnancy (days 15-21) caused significant brain cell death in the hippocampus, the brain region critical for learning and memory. This timing coincides with a crucial period of brain development when new neurons are forming.

Researchers exposed honey bees to 900 MHz radiofrequency electromagnetic fields (similar to older cell phone frequencies) and tracked their behavior for seven days. The exposed bees showed significant changes in walking, flying, and social contact patterns compared to unexposed bees. These findings add to growing evidence that wireless technology frequencies can disrupt natural animal behaviors.

From adults to offspring: Wi-Fi RF-EMR exposure in adult zebrafish impairs reproduction and transgenerationally effects development and behavior of progeny

Unknown authors · 2025

Researchers exposed adult zebrafish to Wi-Fi radiation from a 4G router for 4 hours daily over 30 days, then bred them in EMF-free conditions. The offspring showed increased death rates, physical deformities, and anxiety-like behavior, even though they were never directly exposed to the radiation themselves. This suggests Wi-Fi exposure can damage reproductive health and harm future generations.

Single exposure to near-threshold 5G millimeter wave modifies restraint stress responses in rats

Unknown authors · 2025

Researchers exposed rats to 28 GHz millimeter waves (5G frequencies) at power levels near current safety thresholds and measured stress hormone responses. They found that even single exposures altered stress hormones like corticosterone and noradrenaline for days afterward. This suggests 5G frequencies can trigger biological stress responses at levels currently considered safe.
