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.

Pregnant rats were divided into four groups (control, wave, wave+linalool, linalool), received linalool at 25 mg/kg by gavage for 21 days, and were irradiated from day 0 to day 21 of pregnancy. Offspring were tested on postnatal days 50 and 60 and showed anxiety-like behavior in the EPM test, impaired learning and memory in the Morris water maze and shuttle box, and reduced fEPSP amplitude and slope at the hippocampal CA3-CA1 synapse. Hippocampal iron, copper, manganese, and copper/zinc ratio were increased while zinc was decreased in exposed offspring, and linalool administration reversed the increases and normalized most trace elements except zinc.

Researchers created two groups of seven rats each, one sham control and one exposed to 2100 MHz RF-EMF for five hours per day over 14 days. Brain tissue from exposed rats showed vascular alterations and significant edema. The exposed group had 18.26% tail DNA compared to 4.06% in controls, indicating more cellular damage. Testicular tissue showed significant deterioration of spermatogenic cells. Bax and bcl-2 gene expression changed significantly, while p53 did not.

The study compared emotional effects of single-frequency and dual-frequency electromagnetic radiation in mice while exploring molecular mechanisms. Single-frequency EMR at 2.65 or 0.8 GHz did not induce anxiety-like behavior, whereas dual-frequency EMR at 2.65/0.8 GHz significantly caused anxiety-like behavior. Administering the cannabinoid receptor agonist Win55-212-2 significantly alleviated the anxiety-like behavior, and the antagonist AM251 blocked this effect.

Researchers exposed Arabidopsis thaliana plants to 30,000 pulses emitted through a Koshelev antenna. They monitored expression of genes involved in calcium metabolism, signal transduction, ROS, and energy status. The treatment did not significantly change mRNA levels of calmodulin, ZAT12, RBOH D and F, CAT2, GSH1, GSH2, SnRK1, or TOR. However, APX-1 and APX-6 were significantly induced three hours after exposure. These results suggest that this treatment, although quite strong in amplitude, is mostly ineffective in inducing biological effects at the transcriptional level when delivered by an antenna.

The author previously reported chromosomal damage in human peripheral blood lymphocytes induced by mobile telephony EMFs, a high caffeine dose, and their combination. Human lymphocytes exposed to gamma radiation at 0.1, 0.3, or 0.5 Gy showed more aberrations than those exposed to MT EMFs or high caffeine dose in a dose-dependent manner. Pre-exposure to a single 15-minute MT EMF exposure before gamma radiation increased aberrations significantly more than the sum of individual stressors in all subjects.

Researchers exposed human dermal fibroblasts to continuous and pulsed 1.6 GHz radiofrequency at 0.4 W/kg for 2 hours. Exposure altered heat-shock protein expression, cytoskeletal organization, and increased lysosomes, with autophagosomes only after pulsed exposure. Mitotic spindle anomalies occurred but no significant effects were seen on cell cycle, chromosome segregation, micronuclei, or DNA damage foci.

The study aimed to investigate gene expression changes under exposure to millimeter waves using BRB-seq. Three exposure scenarios compared primary keratinocyte cultures and a HaCaT cell line, tested power-density dose effects, and examined exposure at the ICNIRP limit. Except for high-power heating, the scenarios showed no important gene expression changes, with very few differentially expressed genes mostly linked to heat-shock response, indicating no transcriptional effect under athermal conditions.

Researchers conducted a controlled human intervention trial exposing participants to a UMTS signal via headsets at two specific absorption rates for two hours daily over five consecutive days. Buccal cells were collected from both cheeks before exposure and three weeks later to score micronuclei and other nuclear anomalies. The study found no increase in micronuclei or nuclear buds, but observed a significant increase in binucleated cells and karyolitic cells. No such effects were seen on the less exposed side of the head. The authors concluded that the exposure did not cause acute chromosomal damage but did disturb the cell cycle and cause cytotoxicity.

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.

The study investigated the effects of 1850 MHz RF-EMF exposure at a specific absorption rate of 4.0 W/kg on cortical neurons in mice at postnatal day 28. Daily exposure for 4 weeks significantly reduced the number of mushroom-shaped dendritic spines in the prefrontal cortex. Prolonged exposure over 9 days gradually decreased postsynaptic density 95 puncta and inhibited neurite outgrowth in developing cortical neurons. Expression levels of genes associated with synapse formation, such as synaptic cell adhesion molecules and cyclin-dependent kinase 5, were reduced in the cerebral cortexes of exposed mice. Behavioral assessments using the Morris water maze revealed altered spatial learning and memory after the 4-week exposure period.

Four-week-old male mice were exposed to LTE EMF at a whole-body average SAR of 4 W/kg or to lead at 300 ppm in drinking water for four weeks. The mice underwent open field, marble burying, and nest building tests. LTE exposure increased T3 levels, while lead exposure elevated T3 and T4 and decreased ACTH levels. LTE EMF did not alter gene expression in the thyroid or pituitary glands but significantly reduced hypothalamic Dio2 and Dio3 expression.

Researchers evaluated effects of non-ionizing radiation from three cell phone towers on Allium cepa at five sites with different power densities and a zero-exposure control. Mean power densities at the five sites were 1.05, 1.18, 1.6, 2.73, and 12.9 μW/cm². A significant change in morphology, root length, fresh weight, and dry weight in Allium cepa was observed under the exposure at different sites. Protein content of roots showed significant difference for samples at all sites while bulbs at sites S4 and S5 when compared to control. The samples under exposure to radiation with maximum power density have shown maximum induction of oxidative stress and genotoxicity.

The study assessed the short-term impact of low-intensity 2.45 GHz exposure on young Arabidopsis thaliana plants. Plants were exposed to continuous wave 2.45 GHz microwaves at 1.0 ± 0.1 W m−2 for 48 hours in anechoic chambers. Exposure increased photosynthetic pigments, oxidative stress, guaiacol peroxidase activity, and ascorbic peroxidase activity, while catalase activity decreased. Photosystem efficiency remained unchanged, non-photochemical quenching increased, leaf morphology showed no significant changes, and genomic template stability was unaffected.

Researchers exposed Chinese hamster lung fibroblast V79 cells to a 1950 MHz LTE signal at SAR values of 0.3 and 1.25 W/kg. Exposure to the LTE signal alone did not cause any measurable chromosomal damage, oxidative stress, or changes in cell cycle progression. A 20-hour pre-exposure at 1.25 W/kg before mitomycin-C treatment significantly reduced micronuclei, and ROS formation was significantly decreased at both SAR levels. Shorter pre-exposures, lower SAR, or continuous wave exposure did not alter mitomycin-C-induced micronuclei.

Researchers evaluated the impact of 5G-modulated 3.5 GHz RF EMF on mitochondrial stress in human fibroblasts and keratinocytes exposed for 24 hours at specific absorption rates of 0.25, 1, and 4 W/kg. They found a statistically significant reduction in mitochondrial ROS in fibroblasts at 1 W/kg, a slight but statistically significant enhancement of UV-B effects in keratinocytes at 0.25 and 1 W/kg, and no effect on mitochondrial membrane potential or apoptosis in any cell type or exposure condition.

Researchers exposed 2-day-old Carniolan worker honey bees to radiofrequency fields of 12 V/m, 28 V/m, and 61 V/m for 0.25, 1, and 3 hours. Hemolymph was collected from 40 bees per group immediately after exposure to measure total proteins, glucose, triglycerides, and TAS activity. The 12 V/m and 28 V/m exposure groups showed statistically significant differences in total proteins, TAS, and triglycerides compared to controls in most cases. The researchers concluded that radiofrequency electromagnetic fields disturb honey bee nutrition and the changes may have long-term effects.

Researchers exposed zebrafish embryos to mobile phone radiation at 1800 MHz and 1.13 W/kg for 1 hour daily over 5 days, starting at 1, 6, or 24 hours post-fertilization. No significant changes were observed in survival rate, morphology, oxidative stress, or cortisol levels across any exposure group. However, embryos exposed from 1 hour post-fertilization showed statistically significant reductions in distance travelled and increased yolk sac area compared to controls.

Twelve male rats aged 21 days were randomly assigned to control and EMF groups, with the EMF group exposed to 0.9 GHz EMF for one hour a day over 25 days. Exposure increased kidney tissue volume and weight, total body weight, and levels of lipid peroxidation, glutathione, catalase, and superoxide dismutase in kidney tissue. Histopathological evaluation revealed cortical and medullary bleeding, widespread fibrosis, tubular dilatation and degeneration, glomerular damage, and degeneration of Bowman's membrane, podocytes, and mesangial cells.
