Researchers have found a way to make ordinary aluminum tubes float indefinitely, even when submerged for long periods or punched full of holes. By engineering the metal's surface to repel water, the tubes trap air inside and refuse to sink, even in . ...

Order doesn't always form perfectly--and those imperfections can be surprisingly powerful. In materials like liquid crystals, tiny "defects" emerge when symmetry breaks, shaping everything from cosmic structures to everyday technologies. Now, ...

Quantum computers need extreme cold to work, but the very systems that keep them cold also create noise that can destroy fragile quantum information. Scientists in Sweden have now flipped that problem on its head by building a tiny quantum ...

Scientists have created a device that captures carbon dioxide and transforms it into a useful chemical in a single step. The new electrode works with realistic exhaust gases rather than requiring purified CO2. It converts the captured gas into formic ...

Low-Earth orbit is more crowded--and fragile--than it looks. Satellites constantly weave past each other, burning fuel and making dozens of evasive maneuvers every year just to stay safe. A major solar storm could disable navigation and ...

JWST has revealed a strange early universe filled with ultra-bright "blue monster" galaxies, mysterious "little red dots," and black holes that seem far too massive for their age. A new study proposes that dark stars--hypothetical stars powered by .. ...

AI may learn better when it's allowed to talk to itself. Researchers showed that internal "mumbling," combined with short-term memory, helps AI adapt to new tasks, switch goals, and handle complex challenges more easily. This approach boosts learning ...

A repeating fast radio burst has just given up one of its biggest secrets. Long-term observations revealed a rare signal flare caused by plasma likely ejected from a nearby companion star. This shows the burst source isn't alone, but part of a binary ...

For the first time, astronomers have captured radio signals from a rare exploding star, exposing what happened in the years leading up to its death. The radio waves reveal that the star violently shed huge amounts of material shortly before it ...

Quantum technology has reached a turning point, echoing the early days of modern computing. Researchers say functional quantum systems now exist, but scaling them into truly powerful machines will require major advances in engineering and ...
