Lyrics:
Verse 1
We stayed up late with bright screens humming low,
Built little carriers that know where to go,
From nucleus out to the cytosol tide,
Packing the tools with the edits inside.

Pre-Chorus
Not just the code, but the whole machine,
RNPs ready, sharp and clean,
And when the RNA starts to fray—
We lock it up, we don’t let it fade.

Chorus
Send it, ship it, let it ride the wave,
Keep that guide alive, keep it brave,
Seal at the 3' end, hold on tight,
Turn the wrong to right in a pulse of light.

Verse 2
Aptamer latches—click—pull it near,
Load it heavy, particle-to-particle clear,
More per capsule, more that lands,
Less guesswork in our steady hands.

Bridge
And down the quiet halls where signals dim,
A spark returns at the edge of vision,
Protein back where it used to be,
Not perfect—still—a door in the key.

Final Chorus
Send it, ship it, let it ride the wave,
Keep that guide alive, keep it brave,
Seal at the 3' end, hold on tight,
From dark to dawn in a pulse of light,
Yeah, seal at the 3' end—watch it ignite.
