Being denser than water, the metal sinks—ask any child. A team at the University of Rochester has etched aluminum tubes so ...

Researchers mimicked the air-trapping tricks of diving bell spiders to create aluminum that stays afloat—even when punctured ...

Add Yahoo as a preferred source to see more of our stories on Google. The diving bell spider (Argyroneta aquatica) is the only spider species known to live almost entirely underwater. This is quite an ...

The Argyroneta aquatica maintains a near 100% underwater existence despite relying solely on atmospheric air. Specific low pH environments and high dissolved oxygen levels dictate where these nests ...

Once modified, the aluminum should theoretically stay afloat no matter how long they are forced into water or how heavily they are damaged ...

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

When the treated tube enters water, the superhydrophobic surface traps a stable bubble of air inside the tube, which prevents ...

Researchers have found a way to make ordinary aluminum tubes float indefinitely, even when submerged for long periods or ...

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