Scientists have developed water-repelling metal structures that will prevent ships from sinking even after damage.

When the treated tube is submerged, the water-repelling interior traps a stable air pocket inside. This air prevents the tube ...

A video shows unsinkable metal tubes retaining their buoyancy even after they are damaged or fully submerged for extended ...

More than a century after the Titanic sank, engineers still have hopes of someday creating "unsinkable" ships. In a step ...

Researchers have developed a new process that turns ordinary metal tubes unsinkable - meaning they will stay afloat no matter ...
