Episode notes
Nutrients Outperform Drugs In Some Studies
- Vitamin D and omega-3 supplements showed larger improvements in depressive symptoms than antidepressants in reviewed trials.
- Researchers highlight biochemical links: vitamin D affects serotonin and omega-3 reduces neuroinflammation.
Next‑Gen Satellite Improves Forecasting
- Europe's new weather satellite provides higher-resolution imagery and faster data throughput for forecasting.
- Improved instruments and transmission reduce latency and enhance climate and emergency response modeling.
Local‑First Mail Cuts Delay And Cost
- A 500-mile-limited mail system emphasizes fast, local delivery via decentralized peer nodes.
- The model reduces long-distance inefficiencies but depends heavily on node participation.
