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.

While nerve function wasn't completely impaired, the study demonstrates that EMF exposure during pregnancy can cause permanent developmental changes.

Analysis of the Association of Mobile Phone Usage and Hearing Function in Young Adults

Unknown authors · 2025

Researchers tested hearing function in 78 young adults (ages 17-24) with different levels of mobile phone usage. They found mild to moderate hearing loss at low frequencies (250-1000 Hz) in participants who used phones more than 30 minutes daily for five years, with 4G users showing more hearing damage than 5G users. The study suggests long-term phone use may damage hearing ability in young people.

The effects of short-term and long- term 2100 MHz radiofrequency radiation on adult rat auditory brainstem response

Er H, Basaranlar G., Derin N., Kantar D, Ozen S. · 2025

Researchers exposed adult rats to 2100 MHz radiofrequency radiation (the frequency used by 3G cell phones) for either 1 week or 10 weeks, 2 hours daily. Short-term exposure delayed auditory brainstem responses and caused brain oxidative damage, while longer exposure with rest days showed no harmful effects. This suggests acute cell phone radiation exposure may temporarily impair hearing function.

Nanoparticle-EMF synergism: a study on the combined effects on developmental and behavioral endpoints in Drosophila melanogaster

This study examined the combined effects of 2.4 GHz electromagnetic field (EMF) exposure and zinc oxide nanoparticle (NP) ingestion on fruit flies (Drosophila melanogaster) across multiple generations, measuring outcomes including survival, motor function, oxidative stress, memory, and physical abnormalities. Results showed that 20-minute EMF exposure improved survival in flies exposed to high-dose nanoparticles, while EMF alone caused behavioral impairments and elevated oxidative stress, with some effects reversing in subsequent generations.

Altered development in rodent brain cells after 900MHz radiofrequency exposure

Unknown authors · 2025

Researchers exposed developing rats to 900MHz cell phone radiation at levels considered safe by current regulations (0.08 and 0.4 W/kg SAR). They found significant changes in brain development, including reduced brain growth factors, altered cell division, and disrupted formation of neural connections. The study suggests developing brains may be particularly vulnerable to wireless radiation even at supposedly safe exposure levels.

Possible effects of melatonin and omega-3 on the obesity-related hypothalamic nuclei of the electromagnetic field-exposed offspring rats: a stereological and immunohistochemical analysis

Altun G, Kaplan S · 2025

Researchers exposed pregnant rats to 900 MHz cell phone radiation for 2 hours daily and found their offspring had fewer brain neurons in areas controlling appetite, along with increased anxiety behaviors. The study also examined whether melatonin or omega-3 supplements could protect against these effects, but found limited benefits.

Microwave dynamic therapy induces ferroptosis in colorectal cancer by targeting PTK2B to regulate STAT3-mediated GPX4 expression

Zhou H et al. · 2025

Researchers investigated how microwave dynamic therapy (MWDT) affects colorectal cancer cells, discovering it triggers a specific type of cell death called ferroptosis. The study found MWDT works by disrupting a molecular pathway (PTK2B/STAT3/GPX4) that normally protects cancer cells from oxidative damage. This research suggests microwaves could potentially be used therapeutically against cancer, though this is fundamentally different from the passive, chronic exposure to wireless radiation people encounter daily.
