Researchers have developed metal tubes that are virtually unsinkable by studying how the diving bell spider traps air underwater. The secret lies in microscopic pits that trap air and repel water.
The technology could transform maritime safety, creating ship components that stay afloat even when damaged. The biomimetic approach shows how nature's solutions, refined over millions of years of evolution, can inspire revolutionary engineering advances.
