“…The large number of confounding variables in atmospheric parameters, geographic distributions, and lifestyle variability makes this field notoriously challenging. To facilitate progress, a key challenge is the development of Biometeorological Data Infrastructures (Fdez-Arroyabe et al 2018). These infrastructures can be based on monitoring people and animals in order to collect data and define the vulnerability of individual organisms as well as populations to acclimatize and adapt to normal variability and extreme changes of specific atmospheric parameters.…”

“…Recently, cardiac muscle cells were observed to be influenced by weak magnetic fields in the SR frequency range (Elhalel et al 2019), which appeared dependent on the frequency (most pronounced at 7.8 Hz) rather than amplitude of the induced field. These studies collectively suggest that very weak alternating magnetic fields can indeed potentially influence biological processes and human health, yet a physical understanding of these findings is still absent (Price et al 2020;Fdez-Arroyabe et al 2020).…”

Challenges in coupling atmospheric electricity with biological systems

et al. 2020

The atmosphere is host to a complex electric environment, ranging from a global electric circuit generating fluctuating atmospheric electric fields to local lightning strikes and ions. While research on interactions of organisms with their electrical environment is deeply rooted in the aquatic environment, it has hitherto been confined to interactions with local electrical phenomena and organismal perception of electric fields. However, there is emerging evidence of coupling between large- and small-scale atmospheric electrical phenomena and various biological processes in terrestrial environments that even appear to be tied to continental waters. Here, we synthesize our current understanding of this connectivity, discussing how atmospheric electricity can affect various levels of biological organization across multiple ecosystems. We identify opportunities for research, highlighting its complexity and interdisciplinary nature and draw attention to both conceptual and technical challenges lying ahead of our future understanding of the relationship between atmospheric electricity and the organization and functioning of biological systems.

“…It follows that SR are excellent indicators of lightning activity and distribution on global scales (see e.g., Williams et al, 2021). The possible connection between atmospheric electricity (including SR) and biological systems is another topic with substantial scientific interest (e.g., Elhalel et al, 2019;Fdez-Arroyabe et al, 2020;Price et al, 2021;Savoska et al, 2021;Sukhov et al, 2021). Until the end of the 1980's SR measurements were sparse and due to the restricted computational and data storage capacities long-term continuous recording was not really feasible at that time.…”

Solar Cycle-Modulated Deformation of the Earth–Ionosphere Cavity

et al. 2021

The Earth–ionosphere cavity resonator is occupied primarily by the electromagnetic radiation of lightning below 100 Hz. The phenomenon is known as Schumann resonances (SR). SR intensity is an excellent indicator of lightning activity and its distribution on global scales. However, long-term measurements from high latitude SR stations revealed a pronounced in-phase solar cycle modulation of SR intensity seemingly contradicting optical observations of lightning from satellite, which do not show any significant solar cycle variation in the intensity and spatial distribution of lightning activity on the global scale. The solar cycle-modulated local deformation of the Earth–ionosphere cavity by the ionization of energetic electron precipitation (EEP) has been suggested as a possible phenomenon that may account for the observed long-term modulation of SR intensity. Precipitating electrons in the energy range of 1–300 keV can affect the Earth–ionosphere cavity resonator in the altitude range of about 70–110 km and modify the SR intensities. However, until now there was no direct evidence documented in the literature supporting this suggestion. In this paper we present long-term SR intensity records from eight stations, each equipped with a pair of induction coil magnetometers: five high latitude (|lat| > 60°), two mid-high latitude (50° < |lat| < 60°) and one low latitude (|lat| < 30°). These long-term, ground-based SR intensity records are compared on the annual and interannual timescales with the fluxes of precipitating 30–300 keV medium energy electrons provided by the POES NOAA-15 satellite and on the daily timescale with electron precipitation events identified using a SuperDARN radar in Antarctica. The long-term variation of the Earth–ionosphere waveguide’s effective height, as inferred from its cutoff frequency, is independently analyzed based on spectra recorded by the DEMETER satellite. It is shown that to account for all our observations one needs to consider both the effect of solar X-rays and EEP which modify the quality factor of the cavity and deform it dominantly over low- and high latitudes, respectively. Our results suggest that SR measurements should be considered as an alternative tool for collecting information about and thus monitoring changes in the ionization state of the lower ionosphere associated with EEP.

The Effects of Electromagnetic Fields on Human Health: Recent Advances and Future

et al. 2021

The potential of electromagnetic fields (EMFs) for disease treatment and health enhancement has been actively pursued over the recent decades. This review first provides a general introduction about natural EMFs and related biological effects. Then the recent progress on the EMF treatment of some common diseases (such as cancer, diabetes, wound healing and neurological diseases, etc.) has been carefully reviewed and summarized. Yet, the blindness on the selection of therapeutic EMF parameters still hinders the broad ap-plication of EMF therapy. Moreover, the unclear mechanism of EMF function and poor reproducibility of experimental results also remain big challenges in the field of bioelectromagnetics. Bionics is a useful methodology that gains inspiration from nature to serve human life and industry. We have discussed the feasibility of applying bionic approach on the selection of therapeutic EMFs, which is based on the findings of natural EMFs. Finally, we advocate that the detailed information of EMFs and biological samples should be thoroughly rec-orded in future research and reported in publications. In addition, the publication of studies with negative results should also be allowed.
