Nature Solved It First

Biological resilience changes how engineers build indestructible machines. This beetle withstands 39,000 times its weight by acting like a jigsaw puzzle rather than a solid shield. Its fused wing cases lock and slowly separate to dissipate energy. Aerospace experts now use this interlocking geometry to create safer, fatigue-resistant aircraft components.
