New observations reveal that the relationship between ultraviolet and X-ray light in quasars has changed over billions of years. This unexpected shift suggests the structure around supermassive black holes may evolve with time, challenging a decades ...

A shiny gray crystal called platinum-bismuth-two hides an electronic world unlike anything scientists have seen before. Researchers discovered that only the crystal's outer surfaces become superconducting--allowing electrons to flow with zero ...

A new microchip-sized device could dramatically accelerate the future of quantum computing. It controls laser frequencies with extreme precision while using far less power than today's bulky systems. Crucially, it's made with standard chip ...

Scientists in Japan have confirmed that ultra-thin films of ruthenium dioxide belong to a newly recognized and powerful class of magnetic materials called altermagnets. These materials combine the best of two magnetic worlds: they're stable against . ...

Astronomers have decoded the hidden past of a distant red giant star by listening to tiny vibrations in its light, revealing clues of a dramatic cosmic history. The star, which quietly orbits a dormant black hole, appears to be spinning far faster .. ...

When Earth was a molten inferno, water may have been locked safely underground rather than lost to space. Researchers discovered that bridgmanite deep in the mantle can store far more water at high temperatures than previously believed. During Earth ...

Scientists have discovered a giant cosmic filament where galaxies spin in sync with the structure that holds them together. The razor-thin chain of galaxies sits inside a much larger filament that appears to be slowly rotating as a whole. This ...

This Christmas, astronomers are highlighting a spectacular region of space that looks remarkably like a glowing holiday tree. Known as NGC 2264, this distant star-forming region sits about 2,700 light-years away and is filled with newborn stars ...

Scientists are digging into the hidden makeup of carbon-rich asteroids to see whether they could one day fuel space exploration--or even be mined for valuable resources. By analyzing rare meteorites that naturally fall to Earth, researchers have ...

Researchers have created a new kind of 3D computer chip that stacks memory and computing elements vertically, dramatically speeding up how data moves inside the chip. Unlike traditional flat designs, this approach avoids the traffic jams that limit . ...
