Researchers studied what psychological factors influence people's intentions to use mobile phones while driving, examining attitudes, social pressure, and risk perceptions across different driving scenarios. They found that personal attitudes consistently predicted phone use intentions while driving, and pressure from others influenced some decisions, but surprisingly, risk perception didn't make people choose safer driving behaviors. This suggests that reducing distracted driving requires multiple approaches targeting different psychological motivations.

Swedish researchers surveyed 2,000 teenagers about their wireless phone use and health symptoms. They found that regular users of mobile and cordless phones reported more health problems including tiredness, headaches, anxiety, concentration difficulties, and sleep disturbances compared to less frequent users. Nearly all teens (99.6%) had access to mobile phones, with girls using them more frequently than boys.

Researchers exposed 90 pregnant women to mobile phone electromagnetic fields for 10 minutes and measured heart activity in their unborn babies and newborns. They found that even this brief exposure significantly increased fetal and newborn heart rates while decreasing cardiac output (the amount of blood the heart pumps). These cardiovascular changes occurred in both developing babies in the womb and healthy newborns after birth.

Japanese researchers developed detailed computer models of pregnant women at different stages of pregnancy (13, 18, and 26 weeks) to study how radiofrequency electromagnetic fields are absorbed by both mother and fetus. The models included 56 different tissue types and calculated specific absorption rates (SAR) - essentially how much EMF energy different body parts absorb during whole-body exposure. This research provides the foundation for understanding EMF exposure risks during pregnancy, when both mother and developing baby may be vulnerable.
Maccà I et al. · 2008
Italian researchers measured electromagnetic field exposure for physiotherapy workers using microwave therapy, diathermy, and magnetic therapy equipment across eight clinics. They found that workers operating these devices were exposed to EMF levels that exceeded European safety limits, particularly when standing within about 50 centimeters of the equipment. The study reveals that healthcare workers using EMF-based therapies may face occupational health risks that aren't being properly managed.
Landgrebe M et al. · 2008
Researchers compared 89 people who report electromagnetic hypersensitivity (EHS) with 107 healthy controls using brain stimulation tests and cognitive assessments. They found that EHS patients had measurable differences in brain function, including reduced ability to distinguish between real and fake electromagnetic stimulation, and altered patterns of brain excitability that varied by age. The study suggests these individuals may have genuine neurobiological differences that make them more vulnerable to electromagnetic effects.

Indian researchers studied how TV tower radiation at 41 and 202 MHz frequencies affects different human tissues including skin, muscle, bone, and fat. They calculated how electromagnetic waves penetrate the body and cause different amounts of energy absorption (called specific absorption rate or SAR) in different tissues. The study concluded that TV transmission towers should be located away from populated areas because their radiation can harm body tissues, and people should maintain safe distances from these towers.
Khan MM. · 2008
Researchers surveyed 286 medical students about their mobile phone use and health symptoms. They found that 44% of students linked their health problems to phone use, with the most common complaints being memory problems (41%), sleep issues (39%), and concentration difficulties (34%). The study suggests that even moderate daily phone use may be associated with multiple neurological and physical symptoms.
Jauchem JR. · 2008
This comprehensive review examined research from 1998 to 2006 on how radio frequency energy (the type emitted by cell phones and wireless devices) affects human cardiovascular, reproductive, and immune systems. The researchers analyzed dozens of studies and found mostly weak or inconsistent evidence of health effects, with most studies showing no significant impacts. However, some studies did report cardiovascular changes like altered heart rate patterns and immune system changes in workers exposed to radar and radio transmissions.
Huss A et al. · 2008
Researchers analyzed 59 studies on radiofrequency radiation health effects to see if funding sources influenced results. They found that studies funded exclusively by the telecommunications industry were 90% less likely to report harmful health effects compared to studies funded by public agencies or charities. This pattern held even after accounting for study quality and other factors.
Hardell L, Carlberg M, Söderqvist F, Hansson Mild K. · 2008
Researchers analyzed data from multiple studies examining whether long-term mobile phone use increases brain tumor risk. They found that when people used phones for 10 years or longer on the same side of their head where tumors developed, the risk of glioma (a type of brain cancer) doubled and acoustic neuroma (a benign tumor) risk increased by 140%. However, using phones on the opposite side of the head showed no increased risk.
Chen ZJ, He JL. · 2008
Chinese researchers reviewed existing studies on whether mobile phone radiofrequency radiation causes DNA mutations, cancer, or birth defects. They found conflicting results across different studies, with most research not supporting the idea that RF exposure causes these genetic effects. However, the authors noted that more research is needed on health effects from low-level RF exposure.
Cardis E et al. · 2008
Researchers measured how radio frequency energy from mobile phones distributes throughout the brain by testing 110 different phone models. They found that 97-99% of the RF energy is absorbed in the brain hemisphere closest to the phone, with 50-60% concentrated in the temporal lobe (the area above your ear). This uneven distribution pattern was consistent across different phone types and suggests that if mobile phones pose cancer risks, brain tumors would most likely develop in these high-absorption areas.

Norwegian researchers studied over 10,000 military personnel to examine whether exposure to radiofrequency electromagnetic fields affects male fertility and the sex ratio of their children. They found that men with higher RF exposure were significantly more likely to experience infertility, with those working closest to high-frequency antennas showing an 86% increased risk. Additionally, fathers with greater RF exposure were more likely to have daughters than sons.
Andrzejak R et al. · 2008
Researchers monitored 32 healthy students' heart rhythms during 20-minute cell phone calls, measuring heart rate variability (how much your heart rate naturally fluctuates between beats). They found that phone calls significantly changed the participants' autonomic nervous system balance, increasing parasympathetic activity (the 'rest and digest' system) while decreasing sympathetic activity (the 'fight or flight' system). These changes returned to normal after the call ended, suggesting that cell phone radiation may directly affect the nervous system's control of heart function.

Researchers studied 361 men at an infertility clinic and found that cell phone use was linked to declining sperm quality. Men who used phones more than 4 hours daily had significantly worse sperm count, movement, survival, and normal shape compared to non-users. This suggests that the radiofrequency radiation from cell phones may be contributing to male fertility problems.

Researchers exposed human cartilage cells (chondrocytes) to pulsed electric fields for 30 minutes and found the cells multiplied 150% more than untreated cells after 72 hours. The study identified the biological pathway responsible: the electric fields triggered calcium signaling, which produced nitric oxide, which ultimately stimulated cell growth. This demonstrates that electric fields can directly influence cellular processes through well-understood biochemical mechanisms.
Perentos N, Croft RJ, McKenzie RJ, Cvetkovic D, Cosic I. · 2008
Researchers exposed 72 healthy volunteers to extremely low frequency (ELF) electromagnetic fields similar to those emitted by GSM cell phones for 20 minutes while monitoring their brain waves. They found that the alpha brain wave activity decreased specifically in the hemisphere of the brain closest to the exposure source. This suggests that the low-frequency electromagnetic fields from mobile phones can directly alter normal brain activity patterns even during rest.
Hountala CD et al. · 2008
Researchers studied how cell phone frequencies (900 MHz and 1800 MHz) affect brain wave coordination patterns during a memory task. They found that RF radiation changed how different brain wave frequencies work together, with effects varying between men and women. The study suggests that cell phone radiation can alter fundamental brain activity patterns even during cognitive tasks.

Danish researchers tracked 13,000 children from pregnancy through age 7, finding those exposed to cell phones both before and after birth had 80% higher odds of behavioral problems like hyperactivity. The findings raise public health concerns given widespread cell phone use.
Zhou ZD et al. · 2008
Researchers exposed human dendritic cells (immune system cells that help coordinate immune responses) to cell phone radiation at 1800 MHz for up to 24 hours. They found that the radiation significantly reduced key surface markers on these cells and impaired their ability to stimulate other immune cells, with effects worsening over longer exposure periods. This suggests that cell phone radiation may weaken immune system function at the cellular level.
Zeni O et al. · 2008
Researchers exposed white blood cells from six healthy people to 3G cell phone radiation (1950 MHz UMTS) at levels similar to those from phones held against the head (2.2 W/kg SAR). They used intermittent exposures over 24 to 68 hours and tested for DNA damage using two sensitive laboratory methods. The study found no evidence of genetic damage or changes in how cells divide and grow.
Palumbo R et al. · 2008
Italian researchers exposed human immune cells to cell phone radiation for one hour and found a 22-32% increase in caspase 3, an enzyme linked to cellular stress. The effect only occurred in actively dividing cells, suggesting mobile phone radiation may impact growing immune cells.
Nagaoka T, Kunieda E, Watanabe S · 2008
Japanese scientists created computer models of children's bodies to study how radiofrequency radiation from cell phones and WiFi affects kids differently than adults. They found children's smaller size and body proportions change how much electromagnetic energy they absorb, highlighting potential increased vulnerability.
Mortazavi SM et al. · 2008
Researchers tested whether electromagnetic fields from MRI machines and mobile phones increase mercury release from dental fillings. They found that 30-minute MRI exposure increased mercury levels in saliva by 31%, and mobile phone use significantly increased mercury in urine compared to controls. This suggests that common EMF exposures may accelerate the release of toxic mercury from dental amalgam fillings.
