Why Cockroaches Survive Decapitation: The Biology Behind a Week Without a Head

For nearly a century, biologists have known that a cockroach can lose its head and continue walking for days — not as a curiosity, but as a window into a radically different philosophy of life. The insect's open circulatory system, distributed nerve ganglia, and spiracle-based breathing make the head biologically optional in ways that no mammal could survive. Now, engineers are reading that ancient blueprint not as a grotesque fact but as an invitation, building cyborg insects that carry oxygen generators into flooded disaster zones — a collaboration between human ingenuity and 300 million yea
