How spiders spin silk dope into nature’s toughest material

A spider can turn a liquid blend of proteins, water and salt into a remarkably strong, flexible silk fiber in milliseconds. Now, researchers led by chemist Gregory Holland have traced how the silk proteins reorganize into tiny, semiliquid droplets called condensates before solidifying into a fiber. This molecular-level view helps explain how the spider’s silk factory makes a material tougher than Kevlar and stronger than steel. And here’s the exciting part: understanding condensates could help scientists create advanced materials inspired by nature.
