Growing molecular reads
Fibres, the property made in the pull.
A long molecule only becomes a thread while it is being drawn. Which is why having the protein can feel like having the material, and isn't.

Fibres, from the molecule up
Spidroins, with hard patches sitting inside a soft matrix. And the narrowing duct the spider pulls the liquid through, which does as much of the work as the sequence does.

Spider silk, down to the spidroin
Small β-sheet nanocrystals held in a springy matrix. The hard part stabilises, the soft part gives, and toughness is what the two do together.

The marble berry and its stack
The brightest colour known in a living thing, with no pigment anywhere in it. Cellulose layers twisted at a spacing that hands blue back, at about 30% reflectivity.

Brewed the protein, still short of the thread
You can brew spidroin without a spider, and people do. The fibre still comes out weaker, because the drawing and the lining-up is the half nobody has finished.
