# Preserving an organ is different from recovering a mind Organ-specific evidence; limited extrapolation. A 2023 rat study demonstrated kidney cryopreservation using vitrification and nanowarming, followed by life-sustaining transplantation. This shows how preservation and recovery can be evaluated using functional endpoints in a specific organ model. It is not a demonstration of human cryonics, brain-memory preservation, or a person returning after long-term storage.

This page expands the “Preserving an organ is different from recovering a mind” chapter in the neuroscience collection. ## Chapter notes A 2023 rat study demonstrated kidney cryopreservation using vitrification and nanowarming, followed by life-sustaining transplantation. This shows how preservation and recovery can be evaluated using functional endpoints in a specific organ model. It is not a demonstration of human cryonics, brain-memory preservation, or a person returning after long-term storage. Preservation belongs in the literature map because the condition of the original tissue constrains every later claim. A proposed collaboration would define the tissue, what is being preserved, and the functional evidence needed afterward. An attractive structural image would not by itself establish retained function or the persistence of an individual’s experiences. Long-term custody would also require durable institutions, documented responsibilities, funding continuity, and honest failure terms. These are operational problems even before biological feasibility is established. Warlocks would examine the continuity obligations, Paladins their enforceability, and Rogues the ways an agreement could fail. This proposal makes no offer to preserve people or animals and no assurance of future recovery. ## Dossier section [Open this exact section in the Necromancer dossier](/necromancer#preservation-science).
