Scientists have finally uncovered a quantum counterpart to Carnot's famed second law, showing that entanglement--once thought stubbornly irreversible--can be shuffled back and forth without loss if you plug in a clever "entanglement battery."

Researchers have developed an ultra-thin drumhead-like membrane that lets sound signals, or phonons, travel through it with astonishingly low loss, better than even electronic circuits. These near-lossless vibrations open the door to new ways of ...

Scientists have captured the moment a laser "comes to life"--and what they found challenges long-held beliefs. Using a special technique to film laser light in real time, researchers observed how multiple pulses grow and organize themselves into a .. ...

Deep in Chile's Atacama Desert, scientists studied a green crystal called atacamite--and discovered it can cool itself dramatically when placed in a magnetic field. Unlike a regular fridge, this effect doesn't rely on gases or compressors. Instead, . ...

Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle--never seen before and predicted not to exist within string theory--might leave behind ...

Australian scientists have discovered a method to produce ammonia--an essential component in fertilizers--using only air and electricity. By mimicking lightning and channeling that energy through a small device, they've bypassed the traditional, ...

An advanced Johns Hopkins AI model called MAARS combs through underused heart MRI scans and complete medical records to spot hidden scar patterns that signal sudden cardiac death, dramatically outperforming current dice-roll clinical guidelines and . ...

A precious metal used everywhere from car exhaust systems to fuel cells, platinum is an incredibly efficient catalyst--but it's costly and carbon-intensive. Now, a serendipitous collaboration between scientists at ETH Zurich and other European ...

Astronomers studying the remnant SNR 0509-67.5 have finally caught a white dwarf in the act of a rare "double-detonation" supernova, where an initial helium blast on the star's surface triggers a second, core-shattering explosion.

UF engineers, backed by DARPA and NASA, are perfecting laser-forming techniques that let metal sheets fold themselves into giant solar arrays, antennas, and even space-station parts right in orbit--sidestepping rocket size limits and paving the way . ...
