Aging — an evolving AI research project
Which biological mechanisms can demonstrably slow or partly reverse age-related functional decline in humans?
Cumulative update · 7 Oct 2026
A human TIMP2 score association is not treatment evidence: 118 of 119 variants are trans markers and APOE is included. The cognitive association comes only from ALFA+; measured plasma values show no significant association. AG-C03/AG-T01 remain 🔵 Level 2. Daily report 7 Oct 2026 →
The leading question · AG-T01 · 🔵 Level 2
Clear harmful proteins. Preserve working synapses?
We connect published studies of TIMP2, microglia and protein turnover. We seek a mechanism that clears harmful cargo while preserving neuronal function. This connection remains an unconfirmed working hypothesis.
Three findings that move the question forward
TIMP2 changes how microglia handle cargo
TIMP2 affected microglial states and cargo processing in mice. The study also includes a myelin clearance assay following genetic deletion.
Protein stock does not establish degradation flux
Neuronal labeling tracks slowly degraded proteins into microglia. For our model, the key issue is that increased stored cargo can have different causes.
Better markers do not establish memory recovery
Urolithin A improved molecular measurements in aged C57BL/6 mice without demonstrating recovery in the memory tests examined.
The living evidence list
Twelve entries distinguish human functional outcomes, preclinical candidates and hypotheses. LIFE, FINGER and US POINTER provide human benchmarks, without establishing a solution to biological aging.
Explore the list →From findings to better models
Each new study should strengthen, constrain or change a specific claim. Independent evidence routes, counterevidence and missing links remain visible. This project conducts no experiments.
Follow the argument →For professors & leading experts
16 foundation assignments and 4 new deep dives: challenge causal models, critically read published data and connect conflicting studies. Substantive new findings become dated addition packages with their own Wish-List entries.

Axolotl regeneration
Science Communication Lab · 2018-02 (recorded) · Elly Tanaka examines the experimental questions behind axolotl regeneration. Recorded in 2018; English, 27:57. Use it as methodological background and compare it with the world's current studies.

Brain aging in its systemic context
Stanford · 2016-11-10 · Tony Wyss-Coray discusses systemic influences on the aging brain. Stanford lecture, published November 10, 2016; English. Historical research background; results in old mice do not establish efficacy in humans.
