Based on King's College London / SDSU research (Feb 2026) revealing how arginine-tyrosine 'stickers' drive silk formation. Cation-π interactions between these amino acids initiate liquid-liquid phase separation (LLPS), then persist during β-sheet crystallization as shear forces convert the dope into fiber. The result: material stronger than steel, tougher than Kevlar, from a simple molecular trick.","shortDescription":"The molecular trick behind unbreakable silk"}}
