This study tested pulsed low-frequency electromagnetic fields (up to 10,000 Hz; max 21 mT) as a potential alternative sanitation approach for poultry drinking water systems. LF-EMF exposure was linked to variable changes in culturable bacterial counts, with direction depending on system type and some early…

This exposure-assessment study used on-body calibrated personal exposimeters to characterize spatial and temporal variability of personal RF-EMF exposure across microenvironments in five cities in Flanders, Belgium. Brussels showed the highest mean total exposure, while Antwerp had higher downlink exposure than…

This in vitro study compared commonly used pulsed electromagnetic field (PEMF) exposures with electromagnetic fields tuned to satisfy the ion cyclotron resonance (ICR) condition for calcium. After 3 weeks, the calcium ICR condition was associated with increased glycosaminoglycans and type II collagen synthesis and…

This in vitro study exposed human mesenchymal stem cell pellets undergoing chondrogenesis to simulated microgravity (SMG), low-frequency EMF (5 mT, 15 Hz), or both for 3 weeks. SMG significantly changed gene expression and reduced chondrogenic marker expression (including COL2A1). LF-EMF alone showed no…

This animal study exposed rats to 2.4 GHz Wi-Fi radiation for 2 hours at 30 cm from a commercial router and assessed PTZ-induced convulsive behavior. The Wi-Fi "on" PTZ group showed significant differences in seizure event counts and summed severity scores versus comparison groups, while several timing and duration…

This exposure assessment quantified RF-EMF levels using portable, high-sampling-rate devices across 94 outdoor microenvironments and 18 public transport vehicles in six countries. Mean outdoor exposure ranged from 0.23 to 1.85 V/m, and public transport exposure ranged from 0.32 to 0.86 V/m. Exposure varied…

This in vitro study exposed primary cultured astrocytes, microglia, and cortical neurons to 1800 MHz RF-EMF at 4.0 W/kg SAR to assess DNA damage and cellular functions. The authors report no significant induction of γH2AX foci and no significant changes in cytokine secretion or dendrite/synapse morphological…

This experimental rabbit study evaluated retinal effects of GSM cell phone simulator microwave irradiation at different distances and durations. ERG outcomes 7 days after exposure showed no statistically significant differences between groups, although irradiated eyes showed non-significant trends toward greater…

This study reports synthesizing hydroxyapatite and carbonate-substituted hydroxyapatite using ultrasound and microwave radiation as processing methods. The authors report that these physical factors produced calcium-deficient hydroxyapatite and B-type carbonated apatite and increased in vitro bioactivity compared…

This engineering study describes synthesis of nano-metal binary oxide catalysts using complexation and impregnation with ultrasonic intervention for low-temperature catalytic oxidation of toluene under microwave radiation. The La-Co catalyst prepared with ultrasonic intervention is reported to have the best…

This plant study examined whether 2.45 GHz continuous-wave microwave exposure affects electric signaling in Nicotiana benthamiana after leaf burning. The authors report a significant reduction in the amplitude of the injury-evoked variation potential, mainly due to a reduced depolarization rate. The reported effect…

This in vitro study exposed human fetal and adult fibroblasts to 25 GHz microwave radiation and assessed multiple genotoxic and cellular endpoints. The authors report no evidence of direct DNA damage and no apoptosis or changes in prosurvival signalling proteins. However, they report increased total and…

This engineering/materials study tested how microwave heating power affects properties of ZnO nanoparticles produced by microwave solvothermal synthesis. Aggregate size reportedly varied (60–120 nm) with microwave power, while individual nanoparticle size and morphology remained constant (average 27 ± 3 nm) under the…
