Researchers exposed Agrobacterium tumefaciens bacteria to extremely low frequency electromagnetic waves (1.0 Hz square amplitude modulated waves) and found 90 minutes of exposure inhibited bacterial growth by 49.2%. The exposure also caused significant DNA and cellular changes, reduced the bacteria's ability to cause disease in tomato plants, and made antibiotics more effective against the organism.

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.

Chinese researchers analyzed over 32,000 pregnant women in Beijing from 2000-2013 to identify risk factors for early miscarriage. They found that living within 100 meters of a cell tower was an independent risk factor for spontaneous abortion, along with illness during pregnancy, home renovation, pet ownership, and anxiety. The overall miscarriage rate was 3.0% in their study population.

This study examined the effects of 900 MHz radiofrequency radiation exposure on testicular germ cells in Swiss albino mice over 35 days, followed by a 35-day recovery period. The researchers found that RFR exposure caused DNA damage, mitochondrial depolarization, cell cycle arrest at the premeiotic stage, reduced sperm count, and histological changes in testicular tissue, though these effects partially recovered after the exposure period ended.

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.

Researchers exposed developing chick embryos to radiation from 2G and 3G cell phones throughout their development. The study found significant liver damage including cellular structural changes, enlarged cell nuclei, and DNA damage in the exposed embryos. The damage was more severe with 3G radiation compared to 2G radiation.

Researchers exposed female mice to 935-MHz electromagnetic radiation (similar to mobile phone frequencies) before fertilizing their eggs in the laboratory. At moderate and high radiation intensities, fertilization rates dropped and significantly fewer embryos developed to the blastula stage, the critical point needed for implantation. This suggests that cell phone radiation may interfere with early reproductive processes at the cellular level.

This 2017 study examined how long-term evolution (LTE) electromagnetic field exposure affects brain electrical activity by measuring EEG patterns in subjects. The researchers found that LTE EMF exposure reduced spectral power and interhemispheric coherence in the alpha and beta frequency bands of frontal and temporal brain regions, with no significant changes observed across different time periods during and after exposure.

This study examined how exposure to 1800 MHz electromagnetic radiation affects cell death and proliferation in the developing hippocampus of mice at two different developmental stages (postnatal day 7 and day 21). The researchers found that electromagnetic exposure did not induce cell death but did alter stem and progenitor cell proliferation in younger mice, increasing DNA synthesis while reducing cell division and total stem cell numbers, with no significant effects observed in older mice.

Scientists tested garden warblers' ability to navigate using Earth's magnetic field while exposed to weak oscillating magnetic fields at 1.403 MHz. The birds lost their navigational ability when exposed to fields as weak as 2-3 nanotesla, which is thousands of times weaker than what current theories predict should cause disruption. This suggests migratory birds are far more sensitive to electromagnetic interference than previously understood.

Researchers exposed male rats to radio-frequency electromagnetic waves and found altered expression of acetylcholinesterase genes, which are crucial for brain function and neurotransmitter regulation. The rats also showed changes in exploratory behavior and motor coordination. This suggests RF radiation can affect both brain chemistry at the genetic level and observable behaviors in mammals.

Researchers exposed mice to 7.5 kHz magnetic fields (the frequency used in electronic security systems and induction cooktops) for 5 weeks and found memory impairment at higher exposure levels. Mice exposed to 120 μT showed slower learning and poorer memory retention after 48 hours, along with increased brain inflammation markers.

Researchers exposed adult rats to 900-MHz cell phone radiation for one hour daily over 21 days and found significant brain cell death in memory and motor control regions. Two natural compounds, folic acid and Boswellia sacra, protected against this brain damage when given alongside the radiation exposure. The study demonstrates that cell phone frequency radiation can kill brain cells, but certain antioxidants may offer protection.

This study examined the effects of 835 MHz radiofrequency electromagnetic field (RF-EMF) exposure on synaptic vesicles in cortical neurons of mice exposed to 4.0 W/kg SAR for 5 hours daily. The researchers found that RF-EMF exposure significantly decreased the density of synaptic vesicles in presynaptic terminals and reduced expression of synapsin I/II genes and proteins, suggesting potential alterations in neurotransmitter levels in the cerebral cortex.

This study examined the effects of 900 MHz radiofrequency field exposure on HL-60 cells (a human leukemia cell line), investigating markers of mitochondrial DNA damage and oxidative stress.

Researchers exposed three types of brain-related cells to 1800 MHz cell phone radiation at high intensity (4.0 W/kg SAR) for up to 24 hours and found no DNA damage, cell death, or abnormal growth patterns. The study tested multiple neurogenic cell lines and monitored them for up to 48 hours after exposure. The authors concluded that this level of RF-EMF exposure did not harm these particular cells under laboratory conditions.

Researchers exposed Chinese hamster lung cells to 1950 MHz radiofrequency radiation (similar to 3G cell phone signals) for 20 hours at various power levels. They found DNA damage at lower exposure levels but a protective effect at higher levels when cells were later exposed to a cancer-causing chemical. This suggests RF radiation can have both harmful and beneficial effects depending on the dose.
