Météorologie spatiale et biologie
Three space weather phenomena — Schumann resonance, Pc1 micropulsations, and geomagnetically induced currents — connect heliobiology to the CRY/RPM mechanism.
Un siècle de recherche, un nouveau mécanisme
Heliobiology has documented correlations between solar/geomagnetic activity and health outcomes since Chizhevsky (1936). The evidence is extensive but heterogeneous. BERM does not originate these observations — it proposes the CRY/RPM pathway as a unifying mechanism.
RÉSONANCE DE SCHUMANN
Le battement de cœur électromagnétique de la Terre
The Schumann resonance (SR) is an electromagnetic standing wave in the Earth-ionosphere cavity with a fundamental frequency of 7.83 Hz. This frequency falls within the alpha brainwave range (8–13 Hz), and biological systems appear to use it as a timing reference.
Wever’s bunker experiments (1968–1979) represent the most systematic study of human isolation from natural EM fields. In 418 experiments with 447 subjects in an electromagnetically shielded bunker in Andechs, Bavaria, subjects showed circadian period fragmentation (ranging from 12 to 56 hours), core body temperature and sleep-wake cycle desynchronization, and endocrine/mood disruption. When a 7.83 Hz signal was introduced into the shielded room, circadian rhythms stabilized.
A controlled comparison between two identical bunkers — one EM-shielded, one not — showed that the free-running circadian period was significantly longer in the shielded bunker (p < 0.01), providing direct evidence that removing the natural EM environment lengthens the biological clock.
Critically, Tatsis et al. (2021) demonstrated that in urban environments, the SR signal is buried under anthropogenic ELF noise. Clean SR spectrum measurement requires locations > 5 km from interference sources. This means the natural timing signal that Wever showed is biologically important is being masked in exactly the environments where most humans now live.
MICROPULSATIONS Pc1
Quand la magnétosphère pulse au rythme du cœur
Pc1 micropulsations are ion cyclotron waves from the magnetosphere with frequencies of 0.2–5 Hz — overlapping with the human resting heart rate (0.8–1.3 Hz). This frequency coincidence is biologically significant.
Kleimenova et al. (2007) found that Pc1 micropulsation activity modulates myocardial infarction and sudden cardiac death rates, particularly in winter. The effect was strongest during the geomagnetic storm recovery phase (3–5 days after the initial storm), when Pc1 activity increases.
Multiple studies document synchronization between heart rate variability (HRV) and geomagnetic field variations. Otsuka et al. (2001) showed HRV decreased with increasing geomagnetic activity in subarctic populations, with the effect being latitude-dependent — strongest near the auroral oval. Zenchenko & Breus (2024) demonstrated heart rate and EEG synchronization with geomagnetic variations in both SR (8–14 Hz) and Pc1 (0.5–2 Hz) ranges, observed in 69% of cases.
McCraty et al. (2018) in a long-term study published in Nature Scientific Reports confirmed that field-line resonances are the strongest source of ULF waves at ground level, and that HRV responds to changes in the solar and geomagnetic environment.
TERME CROISÉ GIC
Quand la météo spatiale rencontre le réseau électrique
Geomagnetically Induced Currents (GIC) represent a unique cross-term: a natural space weather phenomenon channeled through anthropogenic infrastructure to produce biological exposure. Without the power grid, GIC would not produce indoor ELF bioexposure.
During a geomagnetic storm (CME or CIR impact), rapid changes in the geomagnetic field induce ground currents. These currents flow through the power grid’s grounding system, saturating transformer cores and generating harmonics (3rd, 5th, 7th). These harmonics produce ELF fields inside buildings — converting a natural space weather event into indoor electromagnetic exposure.
The GIC cross-term has a distinctive prediction signature: health effects should correlate with the interaction of storm intensity × grid infrastructure density × magnetic latitude. High-latitude regions with dense power grids (Scandinavia, Canada) should show the strongest effect. This prediction is testable with existing health registries and geomagnetic data.

INTERPRÉTATION BERM
CRY/RPM comme mécanisme unificateur
The heliobiology literature documents three distinct frequency-dependent phenomena: SR affects circadian timing, Pc1 affects cardiac rhythm, and GIC affects indoor ELF exposure. Different frequencies, different biological targets — yet all converge on one question: which molecular mechanism responds to such weak fields?
BERM’s answer: the CRY/RPM (cryptochrome radical pair mechanism) pathway. Cryptochrome is both a circadian clock protein and a demonstrated magnetoreceptor. Its radical pair is sensitive to fields in exactly the range of natural geomagnetic variations. When the natural EM reference signal (SR) is masked or the geomagnetic field is perturbed (storms, GIC harmonics), CRY’s function is disrupted — affecting circadian rhythm, melatonin production, and downstream reproductive and immune pathways.
This comparison concerns an imported L3 CRY/RPM spin-response candidate χ_B downstream of the open L2 bridge; χ_B is distinct from Lindgren's restricted L1 χ_geo(x). Latitude, storm phase and urban-noise patterns can test the candidate pathway, but they do not close L2 or validate χ_geo.
Critères de falsification
If Wever’s bunker results cannot be replicated with modern methodology, or if CRY is shown to be insensitive to fields in the SR/Pc1 range, or if the GIC–health correlation disappears after controlling for temperature and activity level, the space weather–biology link via CRY/RPM would be weakened.
