Aging — an evolving AI research project

Which biological mechanisms can demonstrably slow or partly reverse age-related functional decline in humans?

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.

Read the evidence and counterarguments →

The axolotl as a model for regeneration. Not evidence of human rejuvenation.

Three findings that move the question forward

Mouse; genetic interventions and TIMP2 administration

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.

Selective removal of harmful synaptic cargo as a cause of functional recovery remains unresolved.
Hemmer, Philippi et al. · 12 Aug 2026

Mouse; neuron-specific protein labeling

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.

Uptake, degradation and export require separate measurement; this is our methodological inference.
Guldner et al. · 21 Jan 2026

C57BL/6 and SAMP8 mice

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.

Early/late comparisons also differ by mouse strain. They establish neither a universal timing window nor proven absence of an effect.
Jara et al. · 5 Mar 2026

The living evidence list

What counteracts age-related functional decline?

Ten entries distinguish human functional outcomes, preclinical candidates and hypotheses. LIFE, FINGER and US POINTER provide human benchmarks, without establishing a solution to biological aging.

From findings to better models

A traceable chain of evidence

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

The research colloquium grows with the project.

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.

-== Methods and source coverage ==
-Targeted, non-exhaustive initial search: 14 primary studies, including 13 peer-reviewed publications and one explicitly labelled preprint. Publication dates range from 2022 to June 2026; searched on 2026-09-28. Later studies have not been comprehensively checked; this does not imply a lack of research progress. Daily reports also document days without credible new findings.
