Selection criterion
A question must be important, genuinely open and answerable by a coherent programme.
Scientific questions
Four candidate questions. One future lead concept.
The A–D portfolio is deliberately competitive: each question must survive novelty, mechanistic depth, researcher fit and feasibility review before any one direction becomes the lead programme.

Concept A · 01ExploratoryWhy do biological systems lose resilience with age?
Concept A · 01Exploratory
Why do biological systems lose resilience with age?
- Why it matters
- Resilience provides a cross-scale way to examine how biological systems respond to perturbation.
- What is unknown
- The causal order connecting molecular change, reduced buffering capacity and functional decline remains incompletely resolved.
- Candidate hypothesis
- Concept-stage proposition: declining resilience may be detectable as reduced molecular-network buffering before overt functional change.
- Potential method families
- Multi-OmicsNetwork BiologyLongitudinal Analysis
Concept B · 02ExploratoryWhich molecular aging signatures are causal rather than correlative?
Concept B · 02Exploratory
Which molecular aging signatures are causal rather than correlative?
- Why it matters
- Association with chronological age alone cannot establish a mechanistic role in functional change.
- What is unknown
- The combination of designs and evidence needed to distinguish upstream drivers from downstream correlates is still an open methodological problem.
- Candidate hypothesis
- Concept-stage proposition: perturbation, longitudinal and genetic evidence could identify a smaller set of upstream molecular features.
- Potential method families
- GenomicsCausal InferencePerturbation Design
Concept C · 03ExploratoryHow might molecular structure contribute to loss of protein function in aging?
Concept C · 03Exploratory
How might molecular structure contribute to loss of protein function in aging?
- Why it matters
- Protein function depends on structure, dynamics, interaction and cellular quality-control systems.
- What is unknown
- The quantitative connection between age-associated structural change and system-level functional outcomes remains unclear.
- Candidate hypothesis
- Concept-stage proposition: structural and biophysical measurements may expose functional vulnerability not captured by abundance alone.
- Potential method families
- Structural BiologyMolecular BiophysicsProteomics
Concept D · 04ExploratoryCan heterogeneous aging trajectories be explained mechanistically?
Concept D · 04Exploratory
Can heterogeneous aging trajectories be explained mechanistically?
- Why it matters
- Individuals with similar chronological age can differ substantially in biological function and resilience.
- What is unknown
- Many trajectory models remain descriptive and are not yet linked to experimentally testable molecular mechanisms.
- Candidate hypothesis
- Concept-stage proposition: interpretable multi-layer models may connect trajectory classes to distinct network configurations.
- Potential method families
- Multi-OmicsInterpretable Machine LearningSystems Biology
Evidence criterion
A central proposition must connect to observable outcomes and explicit uncertainty.
Stop criterion
A concept is retired when novelty, fit, feasibility or causal logic cannot be defended.
