The study used tube formation and CCK-8 assays, a Seahorse assay, mitochondrial membrane potential assays, mitochondrial imaging, reactive oxygen species assays, and real-time PCR to examine the effects of PEMFs on human umbilical vein endothelial cells. Tube formation was significantly greater in the PEMF group than in controls. PEMFs shifted HUVEC energy metabolism from oxidative phosphorylation to aerobic glycolysis and caused mitochondria to become shorter and more granular.

In a pilot study, researchers used a Yucatan miniswine model of traumatic brain injury with and without electromagnetic field stimulation to investigate differential gene expression between injured and non-injured cortex tissues. They found several differentially expressed genes including INSC, TTR, CFAP126, SEMA3F, CALB1, CDH19, and SERPINE1. These genes are associated with immune cell infiltration, myelination, reactive oxygen species regulation, thyroid hormone transportation, cell proliferation, and cell migration. There was a time-dependent effect of EMF stimulation on gene and protein expression. The findings support the beneficial effect of EMF stimulation in the repair process following traumatic brain injury.

Researchers used zebrafish scales as an in vivo model to study the effects of extremely low-frequency electromagnetic fields on fracture healing. Exposure to 10 mT ELF-EMFs at 60 Hz increased the numbers of both osteoblasts and osteoclasts at the fracture site, while 3 mT and 30 mT did not. The exposure also upregulated wnt10b and Wnt target genes and enhanced β-catenin expression at the fracture site. Inhibition of Wnt/β-catenin signaling by IWR-1-endo treatment reduced both osteoblasts and osteoclasts in the fractured scale exposed to ELF-EMFs.

The study aimed to determine the effect of electromagnetic waves from mobile phone stations on sperm parameters and the male reproductive system. Researchers enrolled 216 men aged 18 to 60 years, dividing them into two equal groups based on whether they lived close to cell phone tower stations for at least six months or 100 meters away. The exposed group showed a trend toward a lower percentage of normal sperm morphology compared to the non-exposed group, but the difference was not statistically significant. The exposed group also showed trends toward decreased total sperm motility and progressive sperm motility, again without statistical significance.

Researchers conducted a retrospective study of 1495 pregnant women who gave birth at Konya City Hospital between September 2020 and February 2021. They recorded phone model, average daily phone time, and neonatal outcomes including birth weight, length, head circumference, APGAR scores, and delivery type. The rate of delivering a small-for-gestational-age baby was significantly higher in women who used phones with higher SAR values (p=0.001). A SAR cut-off of 1.23 W/kg showed 69.3% sensitivity and 73.0% specificity for predicting SGA birth. No correlation was found between daily phone use time and SGA birth rate.

Researchers measured 0.14 THz wave penetration across mouse skulls and found approximately 70% penetration. They then exposed an Alzheimer's disease mouse model to repeated low-frequency terahertz waves on the head. The treatment significantly improved cognitive impairment and reduced amyloid-β deposition and tau hyperphosphorylation. It also attenuated mitochondrial impairment, neuroinflammation, and neuronal loss in the brain.

The study aimed to evaluate RF-EMF exposure at three time intervals and three distances from BTS antennas in Sabzevar, Iran. Electric field averages and maximum averages differed significantly across time periods, distances of 50, 100, and 300 meters, and between suburban and downtown antenna locations. No significant differences in electric field levels were found across different microenvironments. Residents near BTS antennas reported poor sleep quality, with significantly worse sleep for those living within 100 meters compared to those beyond 300 meters. All measured electric field levels were below safety limits set by Iranian and international standards, indicating no potential risk in the study area.

Researchers evaluated associations between solar and geomagnetic activity and cognitive function in the Normative Aging Study from 1992 to 2013. They used logistic and linear generalized estimating equations to assess moving averages of sunspot number and Kp index in relation to MMSE scores and six other cognitive tests combined into a global composite score. A one-IQR increase in same-day SSN and Kp index was associated with 17% and 19% higher odds of a low MMSE score, while global cognitive score increased slightly with SSN but backwards digit span decreased.

Researchers conducted a randomized, triple-blind, crossover study with 44 healthy young volunteers exposed to 3.5 GHz signals at 1 to 2 V/m. Each session included baseline, exposure, and postexposure phases with seven runs of electrodermal activity recordings stimulated by beeps and skin temperature measurements at the hand, head, and neck. The study suggests a slight increase in head and neck temperature and minimal modulation of electrodermal metrics after exposure, though results remain within normal physiological range and could reflect an uncontrolled variable.

The study found no consolidated disruption in sleep structure. It is the first to show that some sleep parameters seem to have a certain sensitivity to chronic but not acute RF-EMF exposure in preterm newborns. The authors call for further studies to confirm the results and examine possible mid- to long-term sleep-related cardiorespiratory and neurodevelopmental outcomes.

Researchers exposed Mel-Ab melanocytes to 1760 MHz RF-EMF at a specific absorption rate of 4.0 W/kg for 4 hours per day over 4 days. Exposure significantly increased melanin production, indicating enhanced skin pigmentation. Phosphorylation of CREB and expression of MITF were significantly increased after RF-EMF exposure. Tyrosinase expression increased significantly but its activity did not change. Expression of p53 and MC1R also increased significantly.

Researchers identified two neighboring housing estates with relatively low or high RF-EMF from nearby mobile phone base stations and 24 healthy adults who had lived in their homes for at least five years volunteered. Homes were surveyed for EMF and blood samples were tested for oxidative status, DNA alterations, chromosomal damage, and cancer-related genetic markers such as MLL gene rearrangements. Long-term exposure had no measurable effect on MLL gene rearrangements or c-Abl-gene transcription, and lipid oxidation and oxidative DNA lesions were higher but not statistically significant. Dicentric chromosomes, chromatid gaps, chromosomal fragments, and total chromosomal aberrations were significantly higher in the exposed group. No potential confounder interfered with these findings.

Researchers introduced a mathematical model and experimental tool to analyze memory performance in 65 young healthy subjects. Working memory was assessed using the Sternberg test while one subgroup received a ~0.1 μT audio frequency magnetic stimulus applied to both sides of the head near the temporal–parietal area and the other subgroup received a sham stimulus. The model revealed deterioration of working memory that could affect 32% of its operability.

MF treatment significantly enhanced electricity generation and overall energy efficiency of G. sulfurreducens by 50% and 22%, respectively. The response of current to MFs was instantaneous and reversible. Cyclic voltammetry showed redox couples changed from -0.31 to -0.39 V, suggesting that MFs could alter electron transfer components. Genes for periplasmic c-type cytochromes, outer membrane cytochromes, pili, and ribosome were upregulated under MF treatment. Enhanced electron transfer was also linked to overexpression of NADH dehydrogenase I, ABC transporter, transcriptional regulation, and ATP synthase.

Researchers optimized an in vitro differentiation protocol of human hematopoietic stem/progenitor cells to B-cell lineages. Human HSPCs were continuously exposed to 300 mT of 50 Hz magnetic field for 35 days in a blinded manner. The percentages of myeloid or lymphoid cells and their differentiation from pro-B to immature-B cells showed no significant changes compared to the control group. Expression levels of RAG1 and RAG2 in B cells were also similar to those in the control group. Results indicate that 50 Hz magnetic field at 300 mT does not affect human B-cell early differentiation from hematopoietic stem/progenitor cells.

Researchers conducted a population-based case-control study in two Northern Italian provinces, including 182 childhood leukemia cases and 726 matched controls. Exposure was assessed by calculating distance from childhood residence to the nearest transformer station using a geographical information system. Living within 15 meters of a transformer station was not appreciably associated with leukemia or acute lymphoblastic leukemia risk, and similar results were found with a 25-meter buffer. Among children aged five years or older, odds ratios were 1.3 (95% CI 0.1-12.8) for leukemia and 1.3 (95% CI 0.1-12.4) for ALL with the 15-meter buffer, and 1.7 (95% CI 0.4-7.0) for leukemia and 0.6 (95% CI 0.1-4.8) for ALL with the 25-meter buffer.

They assessed mobile phone radiation exposure using daily call time, phone proximity when not in use, phone models, specific absorption rate (SAR), and effective SAR (SAR × call time). Excess weight gain during pregnancy increased CAKUT risk, while folic acid use before pregnancy was protective. Longer daily call time and higher effective SAR values were associated with increased CAKUT risk, but phone proximity when not in use was not a risk factor.
