Episode notes
Boron As A Desert Biochemistry
- Boron can form stable, energy-dense lattices and boron-nitrogen rings that substitute for carbon frameworks in dry, hot deserts.
- Boron-based life could run slow, crystalline metabolisms powered by storm chemistry and stored boranes instead of sugars.
Ammonia As An Alternative Solvent
- Ammonia is a plausible alternative solvent to water because it's common and liquid at much lower temperatures than water.
- Ammonia-based life would run slower but could support membranes, solvated electrons, and different photosynthetic chemistries.
Use Five Principles To Judge Habitability
- When evaluating exoecologies, use the five categories: Environmental Interaction, Ecosystem Design, Ecosystem Dynamics, Material Cycling, and Temporal Cycles.
- Apply these principles to judge whether an environment can support energy flux, recycling, and stable niches for life.
