The science
of recovery
What we can do next depends on how well we recover.
We study how the body restores function after demand, and design therapeutics against three measures of it: speed, completeness and stability.
How far does function change?
How quickly does it return?
What remains unresolved?
What happens with repeated demand?
Recovery biology
The interval between
demand and readiness.
Attention stays impaired after a recovery night that follows repeated sleep restriction.[1] Sleep pressure changes synapse number.[2] Exercise sets off distinct molecular trajectories.[3] Ageing slows the return.[4]
Recovery is our organising question. Sleep, performance and ageing are different settings in which to test it.
Interval
A recovery
interface.
Interval turns a claim about recovery into something an experiment can test.[5][6]
Predict a response
Literature, molecular structure and cell state inform a testable hypothesis.
Test causality
Controlled experiments distinguish an association from a mechanism.
Resolve the change
Sequencing, molecular profiles and functional readouts capture the response.
Revise the prediction
Results and uncertainty determine the next experiment.
Programmes
Two hypotheses.
Retreat
Overnight recovery is limited by the strength of the circadian signal.
Sleep continuity, sleep stages, overnight heart rate variability.
Hunt
Sustained attention is limited by the brain’s energy economy.
Vigilance over time on task, reaction-time variability, effort.
Status
Where the
work stands.
| Stage | Retreat | Hunt | Detail |
|---|---|---|---|
| Literature review | Complete | Complete | |
| Sourcing and testing | In development | In development | Every batch confirmed for identity, purity, salt form and content. |
| Manufacturing | First run complete | First run complete | GMP-certified manufacturers shortlisted. |
| Regulatory | In progress | In progress | |
| Human study | Not yet run | Not yet run |
Evidence
A wider field of evidence.
Two open libraries, with every claim tied to its source. Bioelectrica: how living tissue uses voltage and energy. SovietRX: the Russian pharmacology record, in translation.
An integrity audit of the papers behind our first questions is in preparation.
Materials & delivery
Materials, geometry
and exposure.
What a therapeutic does depends on where it goes, at what concentration and for how long.[7][8] We develop the compound and its delivery together.
Material behaviour
Compatibility, network structure, stiffness and transport.
Geometry & fabrication
Shape, surface area, dimensional precision and batch consistency.
Exposure over time
Release profile, tissue distribution, clearance and retained activity.
Research in India
Population impact
Recovery at
population scale.
Cost, stability and ease of use decide who can benefit. They shape development from the start.
Therapeutics for human ambition should give more people the health to pursue theirs.
The research record
Methods others can build on.
We will publish methods and results, including those that change our direction.
Bioelectrica is the first part of that record to be open.
