In the present study, the TUNEL (Terminal deoxynucleotide transferase dUTP Nick End Labeling) assay--a well known technique widely used for detecting fragmented DNA in various types of cells--was used to detect cell death (DNA fragmentation) in a biological model, the early and mid stages of oogenesis of the insect Drosophila melanogaster. The flie...

A biophysical model for the action of oscillating electric fields on cells, presented by us before [Biochem. Biophys. Res. Commun. 272(3) (2000) 634-640], is extended now to include oscillating magnetic fields as well, extended to include the most active biological conditions, and also to explain why pulsed electromagnetic fields can be more active...

We examined whether exposures to mobile phone radiation in biological/clinical experiments should be performed with real-life Electromagnetic Fields (EMFs) emitted by commercially available mobile phone handsets, instead of simulated EMFs emitted by generators or test phones. Real mobile phone emissions are constantly and unpredictably varying and...

In the present study we analyze the role of polarization in the biological activity of Electromagnetic Fields (EMFs)/Electromagnetic Radiation (EMR). All types of man-made EMFs/EMR - in contrast to natural EMFs/EMR - are polarized. Polarized EMFs/EMR can have increased biological activity, due to: 1) Ability to produce constructive interference eff...

We describe a biophysical mechanism for animal magnetoreception, orientation and navigation in the geomagnetic field (GMF), based on the ion forced oscillation (IFO) mechanism in animal cell membrane voltage-gated ion channels (VGICs) (IFO-VGIC mechanism). We review previously suggested hypotheses. We describe the structure and function of VGICs an...

I previously reported chromosomal damage in human peripheral blood lymphocytes (HPBLs) induced by: a) mobile telephony (MT) electromagnetic fields (EMFs)/electromagnetic radiation (EMR), b) a high caffeine dose, and c) the combination of the two stressors. HPBLs from the same subjects exposed to gamma radiation at doses 0.1, 0.3, or 0.5 Gy, display...

All types of man-made electromagnetic fields (EMFs) and corresponding non-ionizing electromagnetic radiation (EMR) produced by electric/electronic circuits and antennas – in contrast to natural EMFs/EMR – are totally polarized and coherent. Polarized/coherent EMFs/waves can produce constructive interference and amplify their intensities at certain...

A plethora of studies show that exposure of living organisms to man-made polarized and coherent electromagnetic fields (EMFs), especially in the Extremely Low Frequency (ELF) and the microwave/Radio Frequency (RF) bands, may lead to oxidative stress (OS) and DNA damage. DNA damage is associated with mutations, cell senescence, cell death, infertili...

Induction of DNA fragmentation in fruit fly ovarian cells after in vivo exposure and chromatid-type aberrations in human peripheral blood lymphocytes (HPBLs) after in vitro exposure to mobile telephony (MT) electromagnetic fields (EMFs) from mobile phones are presented. In both cases, the biological samples were exposed in close distance to a comme...

Exposure of living organisms to man-made electromagnetic fields (EMFs) causes a variety of adverse biological and health effects including oxidative stress (OS), genetic damage, cell death, and cancer, as is today documented by a great number of indisputable scientific studies. How does this happen? Key signaling molecules in all cells are the mobi...

Exposure of animals/biological samples to human‑made electromagnetic fields (EMFs), especially in the extremely low frequency (ELF) band, and the microwave/radio frequency (RF) band which is always combined with ELF, may lead to DNA damage. DNA damage is connected with cell death, infertility and other pathologies, including cancer. ELF exposure fr...

I recently reported induction of chromatid-type aberrations in human peripheral blood lymphocytes after a single 15 min exposure to Universal Mobile Telecommunications System (UMTS) Mobile Telephony (MT) electromagnetic field (EMF) from a mobile phone. Lymphocytes from six healthy subjects were stimulated for mitosis, and exposed during the G2/M ph...

The paper by Geronikolou, et al. (2014) “Diverse Radiofrequency Sensitivity and Radiofrequency Effects of Mobile or Cordless Phone near Fields Exposure in Drosophila melanogaster” [1] published in Plos One supposedly presents original work on the effects of mobile and cordless phones electromagnetic fields (EMFs) on Drosophila melanogaster reproduc...

It is documented that a few days or weeks before major Earthquakes (EQs) there are changes in animal behavior within distances up to 500 km from the seismic epicenter. At the same time Seismic Electric Signals (SES), geomagnetic and ionospheric perturbations, are detected within similar distances. SES consist of single unipolar pulses, and/or group...

Environmental exposure to modern microwave telecommunication electromagnetic fields (EMFs) has increased to unprecedented levels with consequent health complaints and concerns. Many studies have already reported genotoxic effects on a variety of organisms and cell/tissue types. Human peripheral blood lymphocytes from six healthy donors were stimula...

In this study I argue that the energy of man-made electromagnetic fields (EMFs) and corresponding electromagnetic radiation (EMR) with frequencies starting from 0 Hz and approaching the low limit of infrared (3×10 11 Hz) is not quantized, in contrast to molecular/atomic/nuclear (natural) EMFs/EMR (frequencies from infrared to gamma rays). Molecula...

Exposure of Drosophila melanogaster young adult insects to Electromagnetic Fields (EMFs)/Radiation (EMR) emitted by an active GSM (Global System for Mobile telecommunications) mobile phone handset during a usual “talk” operation for a few minutes daily for 2–5 days, revealed an impressive decrease (up to 57%) in reproductive capacity (fecundity) (P...

Abstract This article tries to answer the review paper from Verschaeve (2014 ). This review paper attempted to dismiss every study that shows negative effects of microwave radiation on living organisms. His conclusions are not supported by scientific data and are mostly based on his claims for “inaccurate” dosimetry. This issue is not the case, e...

Purpose To study the effect of pulsed electric field – applied in corona discharge photography – on Drosophila melanogaster reproduction, possible induction of DNA fragmentation, and morphological alterations in the gonads. Materials and methods Animals were exposed to different field intensities (100, 200, 300, and 400 kV/m) during the first 2–5 d...

The present theoretical study examines a possible revision in the current corpuscular photon model, to account for a physical quantum explanation of the light interference facts as originally described in Thomas Young's double-slit experiments as well as in subsequent experiments. The light interference effect still constitutes a "mystery" for quan...

To evaluate SAR as a dosimetric quantity for EMF bioeffects, and identify ways for increasing the precision in EMF dosimetry and bioactivity assessment. We discuss the interaction of man-made electromagnetic waves with biological matter and calculate the energy transferred to a single free ion within a cell. We analyze the physics and biology of SA...

In the present experiments, the effect of 50-Hz alternating magnetic field on Drosophila melanogaster reproduction was studied. Newly eclosed insects were separated into identical groups of ten males and ten females and exposed to three different intensities of the ELF magnetic field (1, 11, and 21 G) continuously during the first 5 days of their a...

In the present chapter we present data showing the electric nature of both our natural environment and the living organisms and how the inevitable interaction between the two, determines health and well-being. We first give a brief theoretical background of electromagnetic fields (EMFs) and waves and delineate the differences between natural and ma...

In the present experiments the effect of GSM radiation on ovarian development of virgin Drosophila melanogaster female insects was studied. Newly emerged adult female flies were collected and divided into separate identical groups. After the a lapse of certain number of hours-different for each group-the insects (exposed and sham-exposed) were diss...

Gametogenesis in all animals, seems to be a much more sensitive developmental stage than later stages of their lives. In Drosophila melanogaster, gametogenesis -especially oogenesis - is shown to be a very sensitive biological phase, in response to exogenous stress factors like radiation - including electromagnetic fields (EMFs) - chemicals, elevat...

While different classes of biological effects of radiation used in modern telecommunications are already confirmed by different experimenters, a lot of contradictory results are also reported. Despite uncertainties, some of the recent results reporting effects show an intriguing agreement between them, although with different biological models and...

Different kinds of biological effects of mobile telephony radiation have been already confirmed by different experimenters, while a lot of contradictory results are also reported. In spite of any uncertainty, some of the recent results reporting effects show a distinct agreement between them, although with different biological models and under diff...

To examine the bioactivity of GSM 900 and 1800 (Global System for Mobile Telecommunications) radiations, in relation to the distance from the antenna or to the radiation-field intensities. Drosophila melanogaster adult insects were exposed to the radiation of a GSM 900/1800 mobile phone antenna at different distances ranging from 0 to 100 cm, and t...

The increased bioactivity 'windows' of GSM 900 and 1800 MHz radiations, (Global System for Mobile telecommunications) revealed recently by us and published in this issue, manifesting themselves as a maximum decrease in the reproductive capacity of the insect Drosophila melanogaster, were examined to discover whether they depend on the intensity of...

An increasing number of studies find that pulsed Radio Frequency (RF), electromagnetic radiation of both systems of digital mobile telephony, established and commonly used in Europe during the last years, GSM 900 MHz (Global System for Mobile telecommunications) and DCS 1800 MHz (Digital Cellular System), exert intense biological action on differen...

Pulsed radio frequency, (RF), electromagnetic radiation from common GSM mobile phones, (Global System for Mobile Telecommunications) with a carrier frequency at 900 MHz, “modulated” by human voice, (speaking emission) decreases the reproductive capacity of the insect Drosophila melanogaster by 50%–60%, whereas the corresponding “nonmodulated” field...

Originally, all effects of weak EMF on living organisms were attributed to the increase of the heat in the tissue, which in turn can cause considerable harm to the affected organism. Electromagnetic fields however, affect the internal communication of neural cells. The electric communication pulses are of the order of 1.5 MV/m. The potential differ...

Research reported so far on the Biological Effects of Artificial Electromagnetic Fields (EMFs) has revealed several problems which complicate the possible conclusions on this relatively new scientific area. These include poor reproducibility of experimental results, absence of linear relationship between cause and effect, and absence of validated/g...
