Proposed framework: aging as loss of biological self-correction
The authors propose viewing aging as progressive impairment of biological self-correction and suggest measuring recovery after stress independently of the hallmarks of aging; the framework is a proposal, not a validated tool. [1]
Automatic summary · not editorially reviewed
The key findings
The authors propose a framework in which aging is progressive impairment of biological self-correction, defined as sensing perturbations, scaling a response, repairing or removing damage, terminating the response and recovering while preserving future reserve. [1]
The authors propose measuring correction fidelity independently of the hallmarks using stress-response trajectories such as latency, deviation magnitude, recovery slope or half-time, residual deficit and final functional state. [1]
The authors propose falsifiable predictions about whether dynamic recovery adds information beyond chronological age, frailty and static aging biomarkers. [1]

Proposed self-correction framework for aging
The authors note that longevity science has moved from extending lifespan toward preserving healthspan, resilience and functional independence. The hallmarks of aging, they argue, describe molecular defects but do not by themselves explain how these translate into loss of adaptive function. They therefore propose a complementary framework: aging as progressive impairment of biological self-correction. This is defined as the distributed capacity to sense consequential perturbations, scale a response, repair or remove damage, terminate the response, and recover or re-equilibrate while preserving future functional reserve. The authors state the framework is not meant to replace homeostasis, homeodynamics, allostasis, physiological reserve or resilience, but to link these concepts to the molecular machinery of dynamic recovery.

Proposed recovery measures after stress
The authors propose measuring correction fidelity independently of the hallmarks, using stress-response trajectories. Named measures include response latency, magnitude of deviation, recovery slope or half-time, integrated deviation, residual deficit, overshoot, biological cost, final functional state and preservation of subsequent reserve. They stress that successful recovery need not mean returning to a fixed youthful baseline, because aging may shift the physiological setpoint toward a less favorable but actively defended equilibrium. The text integrates evolutionary and biodemographic principles with inflammaging, nutrient sensing, NAD+ biology, senescence, autophagy, partial reprogramming and resilience research, and proposes falsifiable predictions about whether dynamic recovery adds information beyond chronological age, frailty and static aging biomarkers.

Abstract-only scope of the proposal
This record is an abstract; the full text was not reviewed. The abstract presents a conceptual framework and proposed measurements rather than results from a completed study, so it reports no sample, follow-up or outcome data. The proposed recovery measures and the falsifiable predictions are therefore untested in this text. Whether dynamic recovery adds information beyond chronological age, frailty and static biomarkers remains an open question the authors propose to test.

How to interpret this
Abstract only; the full text was not reviewed. The text presents a proposed conceptual framework and proposed measurements, not results from a completed study, so no sample, follow-up or outcome data are reported and the proposals remain untested here.
Based on the study abstract; the full paper, tables and supplementary data were not reviewed.
