On paper, the S25 Ultra is built around a bright 6.8" QHD+ LTPO AMOLED (2600 nits peak), a 200MP-led quad camera with 3x and 5x optical zoom, Snapdragon 8 Gen 4 (3 nm), and Android 15 with up to 7 major upgrades. The tr…
Effects of paternal 5G RFR exposure on health of male offspring mice
Research
RF Safe Research Library
Jan 1, 2025
This animal study examined whether paternal exposure to 4.9 GHz (5G) radiofrequency radiation affects male offspring in C57BL/6 mice. It reports increased anxiety-like behavior and reduced sperm quality in adult F1 males from exposed fathers, alongside reported LRGUK hypermethylation and reduced LRGUK expression in…

Jan 1, 2025
This modeling study assessed RF-EMF exposure from a 5.9 GHz V2V monopole array antenna integrated into a car roof shark-fin antenna. Using COMSOL simulations with an adult male body model inside a vehicle, the authors estimated localized and whole-body SAR and associated core temperature rise over a 30 min averaging…

Jan 1, 2024
This pilot animal study exposed mature male Wistar rats to 4.9 GHz electromagnetic fields described as 5G-standard, for 15 days (2 hours/day) in a semi-anechoic shielded chamber. Open-field testing found no clear behavioral differences between unmodulated and modulated exposures. Statistically significant behavioral…

Jan 1, 2024
This animal study exposed adult male C57BL/6 mice to a 4.9 GHz radiofrequency field for three weeks (1 hour/day) and compared them with a sham group. The abstract reports altered fecal microbiome composition with reduced diversity in the RF group, along with 258 significantly differentially abundant fecal…
Nonionizing Electromagnetic Field: A Promising Alternative for Growing Control Yeast.
Research
RF Safe Research Library
Jan 1, 2021
This laboratory study examined radiofrequency EMF exposure between 1 and 5.9 GHz as a method to control yeast growth relevant to food spoilage. The authors report reduced yeast viability at all tested frequencies and note that antenna-to-sample distance affected the outcome. Electron microscopy findings are described…
Effects of electromagnetic field (1.8/0.9 GHz) exposure on growth plate in growing rats.

Jan 1, 2016
This animal study examined whole-body RF-EMF exposure (900 or 1800 MHz) for 2 hours/day over 90 days in growing male rats, compared with sham controls. Exposed rats showed greater weight and length increases and higher levels of several hormones and calcium. The study also reports changes in femoral growth plate…
