Membrane oxidation determines whether stress granules gel or stay liquid — and this explains why long-lived species maintain cellular plasticity

Stress granules and P-bodies are membrane-less organelles that manage cellular stress. In short-lived species, they solidify with age. In long-lived species, they stay fluid. Why? The answer may lie in membrane lipid oxidation — not the organelles themselves, but what leaks into the cytoplasm from the cell's edges.
