A method of simulating thermal mapping of positioning laptop on laps of an adult man was developed et al. · 2017
This study developed a method to simulate thermal mapping of laptop positioning on an adult man's lap, measuring temperature increases in the glans penis, lap skin, lap muscles, and testes up to 37°C. The title does not clearly indicate an EMF (electromagnetic field) study, appearing instead to focus on thermal effects from laptop heat exposure.
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.

Researchers studied people living within 80 meters of cell phone towers and found significantly higher DNA damage in their blood cells compared to people living 300 meters away. The study also showed that those closer to towers had reduced antioxidant levels, suggesting their bodies were under greater oxidative stress from the radiofrequency radiation exposure.

This 2017 review examined associations between proximity to cell towers and general symptoms, as well as school radiofrequency radiation (RFR) levels. The study found limited associations between cell tower vicinity and some general symptoms, but found no association with school RFR levels.
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 examined the effects of 50-Hz 2-mT extremely low-frequency magnetic field (ELF-MF) exposure on primary cultured hippocampal neurons using both single and repeated exposure patterns. The results showed that repeated exposure decreased neuronal viability and increased reactive oxygen species production through upregulation of Nox2 expression, while having no significant effects on DNA damage, apoptosis, or autophagy.

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 pregnant mice to 7.5 kHz magnetic fields at two different strengths throughout pregnancy and nursing, then tested the male offspring for learning, memory, and behavioral changes. The study found no meaningful effects on brain development, with only two minor changes that researchers attributed to chance rather than actual EMF effects.

Researchers exposed mice to 7.5 kHz magnetic fields from sources like electronic security systems and induction cooktops for 5 weeks. At higher exposure levels (120 μT), mice showed memory problems and brain inflammation markers, while lower levels (12 μT) had no effect. This suggests intermediate frequency magnetic fields may impair learning through inflammatory brain responses.

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.

This 2017 study systematically examined whether 50 Hz magnetic field exposure at 2.0 mT affected DNA damage and cellular functions in six types of neurogenic cells, including tumor cell lines and primary rat cells. The results showed no evidence of DNA double-strand breaks, altered cell cycle progression, changes in cell proliferation or viability, abnormal cytokine secretion, or effects on neuronal development markers following exposure up to 24 hours.

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 tendon cells to low-frequency magnetic fields (2 Hz, 350 mT) for various time periods and found the fields activated genes involved in tendon healing and altered calcium levels inside cells. Different exposure schedules produced different effects, with some promoting beneficial tendon repair processes. This suggests magnetic field therapy could potentially help treat tendon injuries.

Researchers exposed Salmonella bacteria to a 200 mT static magnetic field for up to 9 hours and measured changes in gene expression. They found that three specific genes involved in cell membrane production increased their activity, suggesting the bacteria were adapting to the magnetic field exposure. This demonstrates that even bacteria can detect and respond to magnetic fields at the cellular level.

Researchers exposed mice to 7.5 kHz magnetic fields for 5 weeks and found that higher exposure levels (120 μT) impaired learning and memory abilities. The mice showed slower learning in maze tests and memory problems after 48 hours, along with increased brain inflammation markers. This suggests intermediate frequency magnetic fields from common devices like induction cooktops may affect cognitive function.
