Researchers exposed Drosophila subobscura at different developmental stages to an extremely low frequency magnetic field (50 Hz, 0.5 mT) for 48 hours. The magnetic field shortened developmental time and increased viability, while sex ratio was unaffected. Regardless of which developmental stage was exposed, the magnetic field significantly decreased locomotor activity in adult flies. When just-eclosed adults were exposed, the observed reduction in locomotor activity lasted longer than in other exposure groups.

Researchers exposed the ciliate Spirostomum ambiguum to 1 GHz and 10 GHz radiofrequency electromagnetic fields at power flux densities ranging from 0.05 to 0.5 W/m2 for periods from 0.05 to 10 hours. Exposure to 0.1 W/m2 of either 1 or 10 GHz radiofrequency fields resulted in a significant decrease in the motility of the ciliates. The motility of unexposed offspring of ciliates that had been irradiated with 0.1 W/m2 of 10 GHz radiofrequency fields remained significantly compromised across at least 10 to 15 generations.

Researchers exposed two nests of the ant Myrmica sabuleti to GSM radiation at 1.5 V/m, the legally allowed level in Brussels, for 10 minutes before observing their behavior. After exposure, the ants' locomotion slightly changed, their orientation toward their alarm pheromone became of lower quality, and their trail following behavior was less efficient.

Researchers performed a repeat study using the same experimental conditions as the REFLEX project to test for genotoxic effects of RF-EMF in HL-60 cells. The repeat experiments found no genotoxic effects of RF-EMF. The authors suggest that the biological significance of the REFLEX study's reported genotoxic effects should be re-assessed.

Researchers exposed cultured human fetal scleral fibroblasts to 0.2 mT ELF-EMF for 24 hours. The cells were treated with puerarin at concentrations of 0, 0.1, 1, and 10 microM. MMP-2 mRNA and protein expression increased by 0.793 and 1.130 folds respectively after ELF-EMF exposure. Puerarin at 0.1 microM reversed the effect by 8.53% in mRNA and 17.97% in protein expression, with greater reversal at 1 and 10 microM.

The aim of the study was to investigate safety zone determination for wireless cellular towers. A model was developed that takes received power, transmitted power, and transmitter gain as inputs to determine safe distance. Power density and geographical location were measured using a selective radiation meter. Transmitted power, transmitter gain, and tower height were obtained from the network operator. Distance from the radiation source was calculated using the haversine formula based on geographical location.

The study conducted a measurement campaign at 827 base station sites with 6207 measurement points in Guangxi, China. The results showed that GSM band EMF levels near the base stations were very low. Measurement results and risk communication procedures positively influenced public perception of RF EMF exposure and promoted knowledge exchange.

Compliance boundaries and allowed output powers were determined for the front, back, and side of antennas based on the root-mean-squared electric field, whole-body averaged SAR, and 10 g averaged SAR in the limbs and head and trunk. The study used ICNIRP basic restrictions and reference levels for both general public and occupational exposure. Antennas were designed for GSM900, GSM1800, HSPA, and LTE with output powers up to 300 W at individual frequencies. Boundaries were estimated using finite-difference time-domain simulations with the Virtual Family Male for three directions at 800, 900, 1800, and 2600 MHz.

The study measured vertical microwave radiation patterns from different BTS antennae in Hashtgerd, Iran. Power density rose with increasing measurement height for both Irancell and Hamrah-e-Aval operators. A significant statistical relationship was found between measurement height and average power density using a mixed model test. The authors noted that installing antennae in crowded areas requires more care due to higher radiation emission, citing rigid surfaces and mobile users as factors increasing wave density.

The study aimed to determine the effects of mobile phone radiation on fasting blood glucose in Wistar Albino rats. Rats exposed for more than 15 minutes per day showed significantly higher fasting blood glucose and serum insulin than controls. HOMA-IR was significantly increased in the 15-30 and 46-60 minute per day groups compared with controls.

Researchers performed indoor measurements using personal dosimeters at 40 locations in urban and suburban Thessaloniki over three days each from July 2010 to January 2012. They found a larger proportion of measurements above detection limits compared to similar European campaigns, with at most 56% for the DCS Rx band. Mean exposure levels in mobile downlink bands were higher than other studies but many times below ICNIRP guidelines. Maximum exposures were of similar magnitude across studies. Base stations dominated in workplaces and schools, while wireless phones and computer networks led in homes, with daytime peaks for the former and evening increases for the latter.

Participants were interviewed about physical activity and cell phone use, had body composition and self-efficacy assessed, and completed a progressive treadmill test to measure peak oxygen consumption. Hierarchical regression was used to assess the relationship between cell phone use and cardiorespiratory fitness after controlling for sex, self-efficacy, and percent body fat. Cell phone use was significantly and negatively related to cardiorespiratory fitness independent of sex, self-efficacy, and percent body fat.

The authors presented a framework that combines near-field and far-field radio frequency electromagnetic exposure sources to calculate average organ and whole-body specific absorption rates. Numerically derived SARs for whole-body and individual organs were combined with realistic exposure data collected using personal exposure meters during the Swiss Qualifex study. For users of GSM 900 or GSM 1800 phones, the 24-hour whole-body averaged exposure was dominated by the user's own mobile phone. If only UMTS phones were used, the average exposure level would be lower due to the lower average output power of UMTS phones. The data indicate the necessity of collecting band-selective exposure data in epidemiological studies of electromagnetic fields.

Preterm birth occurred in 19% of participants and low birth weight in 12.9%. Birth weight correlated positively with maternal age and baseline weight. Mothers with a history of disease during pregnancy had more preterm births and lower birth weight infants. Mobile phone and computer use during pregnancy was associated with more preterm deliveries and shorter pregnancy duration, but not with birth weight.

Researchers exposed rats to 2.45 GHz RF for 1 hour daily over 21 consecutive days, which induced a diabetes-like status. RF exposure decreased glutathione peroxidase, catalase, superoxide dismutase, and thiol group activities in liver and kidneys, while increasing malondialdehyde concentration in both organs. Olive leaf extract at 100 mg/kg prevented glucose metabolism disruption, restored antioxidant enzyme activities and thiol groups in liver and kidneys, and reduced elevated malondialdehyde in liver but not in kidneys.

Some rats had persistent inflammation induced by CFA injection 24 hours before exposure. Rats received tramadol at 20 mg/kg or vehicle before exposure. Single EMF exposure significantly reduced antioxidant capacity in both healthy and inflamed rats. A synergistic effect between EMF and tramadol was observed in CFA-treated rats.

Researchers measured uplink exposure from a mobile phone handset during commuting using a randomized cross-over study with three scenarios: a disabled phone, an activated dual-band phone, and a quad-band phone. In the reference scenario, uplink exposure was highest during train rides at 1.19 mW/m2 and lowest during car rides in rural areas at 0.001 mW/m2. In public transports, the impact of one's own mobile phone on personal RF-EMF measurements was not observable due to high background uplink radiation from other people's mobile phones. In a car, uplink exposure with an activated phone was orders of magnitude higher compared with the reference scenario.
