This tiny molecular trick makes spider silk almost unbreakable

Scientists have cracked a key mystery behind spider silk’s legendary strength and flexibility. They discovered that tiny molecular interactions act like natural glue, holding silk proteins together as they transform from liquid into incredibly tough fibers. This same process helps create silk that’s stronger than steel by weight and tougher than Kevlar.
