Unveiling the secret behind spider silk’s legendary strength! 🕸️

Amino acid “stickers” reveal how spider silk combines strength and flexibility.

Scientists discover how amino acid “stickers” shape its incredible fibers, paving the way for sustainable materials and medical breakthroughs.

Spider silk has long fascinated scientists for its remarkable combination of strength, flexibility, and toughness—stronger than steel by weight and tougher than Kevlar. Now, groundbreaking research from King's College London and San Diego State University has unveiled the molecular interactions behind this natural marvel. Their findings reveal that certain amino acids act as molecular “stickers,” orchestrating the assembly of silk proteins into high-performance fibers.
