A deep dive into independent verification of a radical brain preservation method. Listeners hear about lab-grade versus real-world preservation milestones. Detailed proof steps include aldehyde-stabilized cryopreservation, rigorous third-party EM validation, and stress-test experiments. The episode covers limitations, a narrow post-mortem time window, and efforts to adapt protocols for practical use.

Episode notes
Aldehyde Stabilized Cryopreservation Achieves Nanoscale Proof
- Combining aldehyde fixation with cryoprotection can preserve nanoscale brain structure long-term.
- Aurelia developed Aldehyde-Stabilized Cryopreservation (2015) and demonstrated traceable synapse-level preservation in rabbit and pig brains.
BPF Prize Raised The Bar With Connectomic Standards
- The Brain Preservation Foundation set connectomic traceability and 100-year stability as judging criteria to force neuroscience-grade evidence.
- Ken's connectomics perspective exposed poor quality in prior cryonics EM images and motivated a prize-based challenge.
Use Focused Prizes To Spur High-Risk Research
- Use prize incentives to catalyze niche scientific progress and attract funding and talent.
- Aurelia credits the BPF's $100,000 prize with inspiring her protocol and millions more in preservation investment.
