Researchers investigated the effects of alternating MF generated by PL on spontaneous magnetic alignment in 36 dogs. Behavior was recorded under north–south (NS) and east–west (EW) oriented PL and compared with control conditions lacking anthropogenic MF. Under control geomagnetically calm conditions, alignment was bimodal with a grand mean of 23°/203°. Under NS-oriented PL, alignment remained bimodal with a grand mean of 5°/185°. Under EW-oriented PL, alignment became trimodal with a grand mean of 103°/283°.

Researchers used 21 New Zealand rabbits divided into three groups of seven, with a control group and two groups exposed to 1800 MHz and 2100 MHz radiation. Exposure was maintained at a constant power intensity of 15 dBm for 38 minutes per day under non-thermal conditions with RF levels about ten times lower than normal. Blood-brain barrier permeability was assessed by measuring Evans blue dye in brain tissue using spectrophotometry at 620 nm. No statistically significant difference was found for 1800 MHz exposure, but 2100 MHz exposure produced a statistically significant difference at the 95% confidence level with a decrease in EB values.

Researchers investigated how an altered magnetic field at sunset changes the nocturnal orientation of Pipistrellus pygmaeus by exposing bats to the natural magnetic field, a 120° horizontal shift, or the same shift combined with a reversal of inclination from 70° to −70°. Bats exposed to the 120° shift oriented unimodally northward, while controls showed a bimodal north–south distribution. Bats exposed to both the 120° shift and reversed inclination showed orientation indistinguishable from a uniform distribution. The results suggest that migratory bats calibrate the magnetic field at sunset and are sensitive to the angle of magnetic inclination.

Researchers collected porcine endometrial slices during the peri-implantation period and exposed them to 50 Hz ELF-EMF for 2 hours in vitro. They measured DNA methylation in the promoter regions of EGR2, HSD17B2, ID2, IL1RAP, MRAP2, NOS3, PTGER4, SERPINE1, VDR and ZFP57 using qMS-PCR. Exposure increased methylation of EGR2, ID2, and PTGER4, decreased methylation of IL1RAP and NOS3, and did not change methylation of HSD17B2, MRAP2, SERPINE1, VDR, and ZFP57.

The study used a 500 μT, 50 Hz extremely low-frequency electromagnetic field generated by a Meritt Coil System. Malondialdehyde and glutathione levels were measured, showing increased lipid peroxidation and decreased antioxidant response after exposure. Raman spectroscopy of brain tissue revealed a shift in amide III vibration peaks, structural changes in lipid CH2 vibrations in both hemispheres, and an increased number of amide III bonds in the cerebellum and left-brain tissue. Liver tissue from the exposed group showed higher Raman intensities and structural lipid changes. Principal component analysis distinguished the ELF-MF and control groups, and hierarchical component analysis showed tissues from each group clustered with their own group.

PEMF treatment of cumulus cells at 30 µT for three hours increased cell viability, proliferation, and expression of OCT4, NANOG, SOX2, P53, CCNB1, and GPX while decreasing DNMT1, DNMT3a, GSK3b, and BAX, and PEMF treatment of SCNT embryos at the start of culture raised the blastocyst rate from 42.8% to 51.4% and lowered the apoptotic index to IVF levels without changing total cell number or inner cell mass to trophectoderm ratio. In blastocysts, the treatment up-regulated NANOG, SOX2, CDX2, GLUT1, P53, and BCL2 and down-regulated BAX, CASPASE3, GSK3b, and HSP70 while leaving OCT4, DNMT1, DNMT3a, DNMT3b, HDAC1, and CCNB1 unchanged, and it increased global H3K27me3 without affecting H3K18ac.

The study aimed to investigate the effect of static magnetic fields on epileptiform cortical activity. The first experiment used a pilocarpine rat model with a 0.5 T magnet or sham placed over the skull. The second experiment recorded epileptic-like activity in the visual cortex of a monkey under control and magnet conditions. In rats, seizure-like events appeared after 1–2 hours with the magnet versus 15–30 minutes in controls, and in the monkey the magnet reduced abnormal activity.

Researchers exposed cultured protist species Euglena viridis and Paramecium caudatum to electric fields for 24 hours using a plate capacitor that produced field strengths found near transmission lines. Short-term exposure to low strength electric fields caused changes in population abundance, morphology, and oxidative stress response in both species. As electric field strength increased, the abundance of both species decreased, while at weaker fields fission rates were seemingly promoted. Organisms exposed to stronger electric fields showed decreased size perpendicular to their fission planes and higher DHE and H2DCF fluorescence intensity and superoxide dismutase activity.

This case study of a Wisconsin dairy farm documents how to establish permanent monitoring of ground current and how to determine and remediate both on-farm and off-farm sources. On-farm sources included lighting, variable speed frequency drives on motors, and a radio frequency identification system, while off-farm sources were due to a poor primary neutral return on the utility side. The study found that a step-potential threshold of 1 V RMS at 60 Hz is inadequate to protect dairy cows, as decreases of a few mV peak-peak at higher frequencies increased milk production, reduced milking time, and improved cow comfort.

Researchers exposed newborn rabbits to GSM-modulated 1800 MHz radiation before and after birth and measured oxidative DNA damage, lipid peroxidation, histopathology, and apoptosis in brain tissue. Oxidative DNA damage measured as 8-OHdG increased in rabbits exposed during both intrauterine and extrauterine periods compared to unexposed rabbits and those exposed only after birth. Lipid peroxidation measured as MDA rose only in males with intrauterine exposure, while females showed no difference across exposure groups. Mild neuronal necrobiosis appeared in intrauterine-exposed females and extrauterine-exposed males; gliosis was mildly positive in intrauterine-only and combined-exposure groups, but no apoptosis was detected in any group.

Exposure raised triglycerides and testosterone significantly in all groups, with oil groups showing dose-dependent increases. Exposed rats had significantly lower SOD and CAT activities than controls, while sesame oil groups showed dose-dependent increases in these enzymes. Total cholesterol decreased significantly only in the 3 ml sesame oil group, which also showed significantly elevated GSH-Rx. HDL-c and LDL-c changed in opposite directions between exposed and sesame oil groups.

Researchers studied how parsley cells responded to 21 ppm iron and a static magnetic field (SMF; 30 mT), measuring antioxidant enzymes and related molecules at 6 and 12 hours after treatments. SMF exposure alone increased catalase activity, but when combined with iron, or with iron alone, catalase activity decreased compared to control cells. The combination of SMF with iron reduced the iron content of cells and lessened iron's negative effect on catalase activity. Ferritin levels dropped significantly in SMF-treated and SMF-plus-iron-treated cells at 12 hours, leading the researchers to question ferritin's proposed role as a reactive oxygen species detoxifying molecule.

Researchers studied how magnetic fields affected antioxidative defense and fitness-related traits in Baculum extradentatum, a stick insect. One group was exposed to a constant magnetic field of 50 mT, another to an alternating magnetic field of 50 Hz and 6 mT, and a control group was kept out of influence of the magnets. SOD and CAT enzyme activities were increased in animals exposed to constant and alternating magnetic fields, while GSH content was not influenced. Significant differences in development timing were found between the control and the CMF group, and between the CMF and the AMF group, but nymph mass and egg mortality did not differ across groups.
