- Discussion of Natasha Vita-More’s experiments showing that learned behavioral responses survive vitrification and reanimation, providing early evidence that memory can persist through cryopreservation (though not yet scaled to large mammals).  
- Kenneth Hayworth’s Aldehyde-Stabilized Cryopreservation (ASC) highlighted as a breakthrough that combines glutaraldehyde perfusion fixation with cryoprotectant vitrification to achieve long-term, whole-brain preservation while retaining synaptic structure.  
- Debate over disciplinary boundaries: Hayworth’s work is viewed as neuroscience by cryonicists and as cryonics by neuroscientists, illustrating the gap between mainstream brain preservation research and radical life-extension communities.  
- High-pressure freezing (HPF) cited as the gold-standard for ultrastructural fidelity in small tissue samples (<1 mm), used to benchmark the artifacts introduced by glutaraldehyde fixation in ASC protocols.  
- Reference to a 1989 paper (doi:10.1016/0013-4694(89)90033-3) showing that cold-induced cessation of neural spiking does not erase long-term memories, bolstering the argument that static preservation can retain identity-relevant information.  
- Link shared to an eLife paper (https://cdn.elifesciences.org/articles/05793/elife-05793-v1.pdf) providing comparative electron-microscopy data on HPF vs. aldehyde-fixed brain tissue.  
- Mention of MIT Technology Review article “The Transhumanist DIY Designer Baby Funded with Bitcoin” as a recent mainstream coverage point of DIY biohacking and cryptocurrency-funded human enhancement projects.
