Researchers measured the effects of morphine and EMF, in combination with β-lapachone, on cell growth inhibition and expression of antioxidant genes in SH-SY5Y cells. The study used 0.50 mT intensity of 50 Hz EMF under two exposure conditions: "15 min field-on/15 min field-off" and "30 min field-on continuously." Under the "15 min field-on/15 min field-off" condition, NQO1 mRNA level decreased while NQO2 expression increased. Multiple linear regression analysis indicated that NQO1 mRNA levels were associated positively with β-lapachone and negatively with EMF.

Researchers tested four treatment combinations on MCF-7 and SH-SY5Y cells: cisplatin alone, cisplatin with morin, cisplatin with electromagnetic field, and cisplatin combined with both morin and electromagnetic field. The electromagnetic field was applied at 50 Hz and 0.50 mT using a cycle of 15 minutes field-on followed by 15 minutes field-off. The IC50 value of cisplatin in the cisplatin-plus-morin-plus-EMF treatment was significantly higher than cisplatin alone and the cisplatin-plus-morin treatment in both cell lines. In SH-SY5Y cells, most of the antioxidant genes showed upregulation with the cisplatin-plus-EMF and cisplatin-plus-morin-plus-EMF treatments, while antioxidant gene expression patterns were similar across the four treatments in MCF-7 cells.

Researchers exposed Wistar albino rats to upward- or downward-oriented static magnetic fields for 50 days, then measured enzyme activities and oxidative stress markers in synaptosomes isolated from the whole rat brain. Chronic exposure to 1 mT static magnetic field significantly increased ATPase and acetylcholinesterase activities, and raised malondialdehyde levels in both exposed groups compared to controls. Synaptosomal catalase activity was significantly decreased in the group exposed to the downward-oriented field compared to both the control group and the upward-oriented field group.

Researchers exposed rats to Wi-Fi radiation (2.4 GHz) for 24 hours daily over one full year and found measurable hearing damage. The study showed decreased hearing sensitivity at 6000 Hz frequency, suggesting that chronic Wi-Fi exposure may harm auditory function. This represents one of the longest-duration Wi-Fi exposure studies conducted on hearing health.
Conclusion The study was an attempt to draw attention towards the adverse effects of non-ionizing electromagnetic radiations (NI-EMR) in the frequency that is used widely in the field of telecommunication et al. · 2017
Researchers used computer simulations to study how laptops affect body temperature through both heat and electromagnetic radiation. They found that laptops in high-performance mode combined with WiFi antennas can raise skin temperature by 5.6°C and testicular temperature by 1.4°C. The study demonstrates that thermal effects from laptop heat are far more significant than the electromagnetic radiation itself.
Decreases in sleep duration among U.S. adolescents 2009-2015 & association with new media screen time Twenge JM et al. · 2017
Researchers analyzed sleep data from nearly 370,000 U.S. adolescents between 2009 and 2015, finding teens became 16-17% more likely to sleep less than 7 hours per night. The study linked this decline directly to increased screen time from electronic devices, social media, and online activities, while other potential causes like homework or TV watching remained stable.

This study investigated whether low frequency-pulsed electromagnetic fields (LF-PEMFs at 60 Hz, 10 mT) could provide neuroprotective effects in mice following ischemic stroke. The researchers found that LF-PEMF treatment activated the BDNF/TrkB/Akt signaling pathway, increased pro-survival proteins, and decreased pro-apoptotic proteins and inflammatory mediators in stroke-affected mice.

Researchers exposed mouse brain cells to pulsed electromagnetic fields (PEMF) and found the treatment protected cells from glutamate damage, a process linked to neurological diseases like Alzheimer's and stroke. The protection worked by activating the brain's natural endocannabinoid system, the same pathway that cannabis affects. This suggests PEMF therapy could potentially help treat neurodegenerative conditions.

Researchers exposed rats to low-frequency magnetic fields (30-50 Hz) while giving them morphine to see how it affected drug tolerance development. They found that specific magnetic field exposures could prevent rats from building tolerance to morphine's pain-relieving effects. This suggests electromagnetic fields might influence how the body processes certain medications.

This study investigated whether combined exposure to pulsed electromagnetic fields (PEMFs) and sound waves could synergistically promote neural differentiation of human bone marrow mesenchymal stem cells both in laboratory culture and in a mouse model of stroke. The combined wave stimulus accelerated neural gene expression and protein markers more effectively than either stimulus alone, and reduced brain infarction volume while improving behavioral recovery in the animal model.

Researchers studied how pulsed electromagnetic fields (PEMFs) help heal bone fractures by examining their effects on human bone marrow stem cells. They found that PEMFs activate specific molecular pathways, particularly involving microRNA 21 and TGF-β signaling, that transform stem cells into bone-building cells called osteoblasts. This research helps explain why PEMF therapy has been clinically successful in treating difficult-to-heal bone fractures.

Researchers exposed breast cancer cells and brain cells to 50 Hz electromagnetic fields combined with chemotherapy drugs cisplatin and bleomycin. The EMF exposure made breast cancer cells more vulnerable to the treatment, while brain cells remained protected. This suggests power line frequency EMF might help target cancer while sparing healthy neurons.

Researchers exposed human umbilical vein endothelial cells (HUVECs) to 50 Hz pulsed electromagnetic fields at 2.25 mT for 15 minutes, combined with hydroxytyrosol (HTY, an antioxidant compound). The combination treatment enhanced cell proliferation and migration while reducing cell death, effects not seen with PEMF exposure alone. This suggests certain antioxidants may protect cells from EMF-induced stress, supporting the potential therapeutic use of PEMFs in wound healing when combined with protective compounds.

Researchers tested whether extremely low-frequency electromagnetic fields (100 Hz, 100 Gauss) could enhance the cancer-fighting effects of temozolomide, a chemotherapy drug used for aggressive brain tumors called glioblastoma. They found that combining EMF exposure with the drug significantly increased cancer cell death compared to using either treatment alone. This suggests EMF might help overcome drug resistance in one of the deadliest forms of brain cancer.

This study used numerical dosimetry models to compare how infant, child, and adult bodies absorb radiofrequency energy from electronic article surveillance (EAS) systems operating at 125 kHz and 13.56 MHz. The findings showed that infants had significantly higher specific absorption rate (SAR) values in brain and central nervous system tissues compared to adults (1.5 to 112 times higher depending on frequency), though safety limits were unlikely to be exceeded.
