Topic 1.2
Science of pausing life
The central claim of Biostasis is that identity survives if information survives. But you can't just assert this and move on. You need to grapple with what identity actually is at the physical level, then check a particular preservation technique can plausibly maintain those structures. This topic exists to bridge the gap between "freezing might work in principle" and "here's the actual chemistry and biology that makes it credible." The goal is to transform cryopreservation from a thought experiment into something with real mechanistic grounding.
Memory, identity and the brainYou are not your atoms, you are the way they are arranged. Why memory and identity live in the brain's structure, and what that means for what we actually have to preserve.What makes you, you? by Tim UrbanEXTERNALPreservation without freezing Preservation without freezing: what vitrification is, what it achieves, and what it explicitly does not do.What is ischemia and how does it influence cryopreservationCryonics is an emergency, not a storage problem. Why oxygen starvation in the first hours is the field's biggest enemy, and how a standby team fights the clock.What is the difference between Freezing and Vitrification?Cryonics does not freeze people. The difference between shattering tissue with ice and setting it gently in glass is the whole game.The medical antifreeze (aka Cryoprotectant)The medical antifreeze that makes vitrification possible, and the toxicity tradeoff the entire procedure is built around.Vitrification vs fixationAdvancing the fieldCryonics is an active research field. The four problems it is working on, with cryoprotectant toxicity first, what has actually been demonstrated and in which species, and how preservation quality is measured.Relevant research papersAn annotated reading list grouped by what the papers actually establish: the premise the field rests on, what has been preserved, what has recovered function, and what has not been shown.
