Spiders don’t just spin webs—they engineer them. By stretching their silk as they spin, spiders strengthen the fibers at the molecular level, aligning proteins and forming extra bonds that boost durability.
Scientists have now cracked this secret using computational simulations and lab experiments, paving the way for bioengineered silk with game-changing applications, from medical sutures to ultra-strong body armor.
When spiders spin their webs, they use their hind legs to pull silk from their spinnerets. This pulling action does more than just release the silk—it strengthens the fibers, making the web more durable.
