Unsinkable metal discovery could build safer ships and harvest wave energy
Laser-etched superhydrophobic textures let damaged aluminum tubes trap air and remain buoyant, mimicking diving bell spiders' hair-based air-trapping mechanism.
Could You Use a Rowboat to Walk on the Seafloor Like Jack Sparrow?
An upside-down dinghy can trap breathable air underwater only briefly and under limited conditions because buoyancy, pressure, and air dilution make sustained breathing impractical.
