Study reveals condensate mechanism behind spider silk formation
What happened
On October 29, Hacker News' front page reported that Gregory Holland's team at San Diego State University uncovered the atomic-level mechanism by which spider silk protein turns from liquid "silk dope" into solid silk. The study found that black widow silk protein first assembles into semi-liquid condensate droplets through liquid-liquid phase separation, then solidifies into silk, rather than the liquid crystal or micelle structures previously assumed. The finding clarifies the role of condensates in silk formation and offers molecular-level design guidance for biomimetic high-strength silk materials.

圣地亚哥州立大学 Gregory Holland 团队揭示了蜘蛛丝蛋白从液态“丝浆”经液-液相分离形成凝聚液滴、再固化成丝的原子级机制。研究发现，黑寡妇蜘蛛的丝蛋白先组装成半液态凝聚物，而非传统认为的液晶或胶束结构。该机制为仿生制造高强度丝材料提供了分子层面的设计指南。
