Coredeath

Coredeath is a term used predominantly in speculative biology and science fiction to denote an irreversible state in which essential core functions of a cell, tissue, or organism fail in a way that ends viability. It is not a standard term in peer-reviewed biology, and there is no consensus on a precise definition or diagnostic criteria.

Usage and scope: In fictional settings, coredeath is often described as crossing a threshold beyond which recovery is impossible, distinguishing it from reversible stress or transient metabolic collapse. Variants describe coredeath as the failure of central processing units of artificial lifeforms, mitochondrion-driven energy crises, or the loss of a genetic control center, depending on the narrative.

Distinction from established concepts: In real biology, cell death is categorized into apoptosis, necrosis, autophagy, and other regulated processes. Coredeath is generally treated as a metaphor or plot device rather than a formal category, and it is not used in clinical practice or widely cited research.

Etymology and usage: The term combines core, indicating central functional systems, with death. It appears in fan writing, speculative biology circles, and game or novel lore rather than scholarly literature.
