Scorpions go terminator mode and reinforce their weapons with metal

Scorpions go terminator mode by naturally incorporating zinc, copper, and other metals into their stingers and claws, creating a self-repairing exoskeleton that engineers are eager to replicate. This biological armor, which can contain up to 12% metal by weight, is 30% harder than the typical rival arthropod cuticle and withstands repeated impacts without cracking. Researchers have measured a 50% improvement in impact resistance compared to non-reinforced scorpion segments, making this a paradigm for self-healing military armor or industrial tools. The real-world application could slash maintenance costs by $200 million annually if scaled to drone fleets.
