The code assembles.
Every cell carries the same instructions, written in a double helix of DNA.

Why cells grow old.
Aging isn't one thing breaking. It's a handful of linked processes that feed each other. Scroll to watch the code decay and recover.
Errors creep in.
Breaks and drifting marks pile up until the cell can no longer read its own code cleanly.
We restore the signal.
Our programs aim at the damage itself, not the symptoms it causes later.
Copied clean again.
Readable code, healthy copies. That's the goal we measure everything against.

The idea in one paragraph
The genetic code in an old cell is mostly intact. What wears out is the cell's ability to use it properly. Repair, regulation and energy slowly drift off course. Our bet is that if you correct the drift, function comes back.
Small errors pile up.
DNA gets nicked and repaired constantly. The repairs are good but not flawless, and over decades the leftovers add up.
- Strand breaks
- Oxidative damage
- Imperfect repair
Gene switches drift.
Chemical tags decide which genes are on or off. With age those tags slip, and cells slowly lose track of what they're meant to be.
- Methylation changes
- Looser chromatin
- Blurred cell identity
Power runs low.
Mitochondria make less energy and more waste as the molecules that fuel them decline. Low energy makes the first two layers worse.
- Falling NAD⁺
- Weaker mitochondrial clean-up
- More free radicals
Stuck cells spread trouble.
Some cells stop dividing but don't clear out. They release inflammatory signals that nudge their neighbours to age too.
- Cell-cycle arrest
- Inflammatory signalling
- Tissue-wide effects
Fix the drift, and the cell remembers what it was built to do.

How we keep score
Younger has to be measurable.
We score every candidate against several biological age markers at once. One improving marker isn't enough; we look for movement across all of them.
Our in-house clock model is built for fast read-outs, so a small team can test more ideas.
