GrivavaLAB
Independent interdisciplinary research on correlations between space weather — solar activity, geomagnetic disturbances, cosmic rays — and human physiological, psychological, and behavioural patterns as reflected in large-scale open data. Rooted in the tradition of heliobiology and Chizhevsky's pioneering work, extended with modern data-science methods.
Epilepsy vs Space Weather: 4,076-Day Correlation Analysis
We analysed 11 years of daily Google Trends data for epilepsy against 7 space-weather variables (F10.7, Kp, Dst, solar wind, and more). The result: a weak but statistically significant positive correlation with F10.7 solar flux at lag +11 days (r = +0.1417, FDR-corrected). Not proof of a causal link — but interesting enough to dig deeper. Full report with interactive charts inside.

Same pipeline, same 4,076 days — opposite outcome. An initial sunspot correlation (r = +0.102) passed FDR but failed all five robustness tests. The yearly r ≈ 0.71 turned out to be a textbook Simpson's Paradox. This report is why we do robustness batteries.

Full robustness analysis of cortisol levels searches across 4,076 days. No credible relationship with space weather detected.

27 of 427 hypotheses FDR-significant — but all fail robustness (block bootstrap, subperiod stability, placebo). |r| < 0.061 for all variables. No credible relationship between domestic-violence Google searches and space weather.

Open Data & Reproducibility
GrivavaLAB combines publicly available space-weather archives and anonymised aggregate search-interest data (Google Trends) to test for statistically significant associations between solar/geomagnetic activity and population-level health indicators. All methods are documented and reproducible.
Scientific Tradition
Rooted in the tradition of Alexander Chizhevsky's pioneering work on solar cycles and mass behaviour, and contemporary studies linking geomagnetic disturbances with cardiovascular and neurological outcomes. We aim not to confirm a hypothesis, but to rigorously evaluate the evidence using modern data-science methods.
Open Science
All code, data pipelines, and intermediate results are documented and shared openly. Questions this fundamental deserve transparent, community-verifiable answers.
Interdisciplinary Scope
Bridging heliophysics, epidemiology, neuroscience, and data science to explore how space weather may influence human physiology and behaviour at population scale.

Methodology
Reproducible analysis pipeline:
All analyses in Python (pandas, SciPy, statsmodels). Lagged correlations (−30 to +30 days). Benjamini–Hochberg FDR correction at α = 0.05. Seasonal decomposition (STL, 365-day) and surrogate-data testing separate genuine signals from periodic artefacts.
