A bioreactor with biofilm exposed to microwave radiation showed an increased rate of organic compounds removal (COD) by nearly half, with maximum process efficiency increased by 7.7%. At a microwave radiation input of 2.5 W s(-1) (reported as optimal), biomass load decreased by over half and pollutant remaining in treated effluent decreased nearly by half; the role of oxidation increased by more than 25% versus control.

The paper uses recorded low-frequency envelopes from GSM and UMTS phone emissions as inputs to dynamical neuron/cell models (Hindmarsh-Rose; adapted Chay-Keizer) and reports that weak GSM/UMTS inputs can induce frequency enhancement and regularization phenomena in the models, proposed as a possible explanation for perturbations of neuro-electrical activity and calcium oscillation regularity under thermal thresholds.

Sexual dysfunction was reported more often in radar operators (43.6%) than controls (24.4%) (P < 0.01). Natural pregnancy rates differed between groups: in the radar group 53.6% occurred within 1 year of marriage and 46.4% after 1 year, versus 81.1% and 18.9% in controls (P < 0.01). The authors conclude long-term low-intensity microwave exposure increased sexual dysfunction and decreased natural pregnancy rate.

A single-Cooper-pair transistor electrometer emitted narrow-band microwave radiation when biased in the subgap region, detected spectroscopically using photoexcitation of quasiparticle tunneling in a nearby SCPT.

The authors analyzed and modeled survival time of multiple animal species during microwave exposure at 0.46, 2.4, and 7 GHz as a function of power flux density (PFD) and specific absorption rate (SAR). When PFD was used as the dosimetric parameter, sensitivity increased with animal mass; when SAR was used, the ordering of species by sensitivity was opposite. Mathematical equations were derived to describe and predict survival time/death during microwave irradiation.

Fourteen male guinea pigs were randomized to control vs EMF exposure from a cellular phone (890–915 MHz, 217 Hz pulse rate, 2 W maximum peak power, SAR 0.95 W/kg) for 12 h/day for 30 days. In brain tissue, MDA increased and GSH and CAT decreased (all P<0.05), while vitamins A, E, and D3 did not change (P>0.05). In blood, MDA, vitamins A/D3/E, and CAT increased (P<0.05) and GSH decreased (P<0.05). The authors concluded the exposure might produce oxidative stress in guinea pig brain tissue.

Tumor induction was 100% in all groups and tumors were histologically leiomyosarcomas. Animals exposed to resonant EMF irradiation after tumor appearance (EG-I) and animals inoculated with EMF-exposed tumor cells (EG-II) showed significantly prolonged survival and lower tumor growth rate versus sham-exposed controls and a non-resonant EMF pattern group. EG-I had significantly longer survival and lower tumor growth rate than EG-II; in EG-I, some tumors completely regressed (final tumor induction 66%).
