Physicists at CERN have found a new way to peer deep inside atomic nuclei and distinguish between two competing explanations for how gluons behave. Using the ALICE experiment at the Large Hadron Collider, researchers measured particle production at unprecedented spatial resolution, revealing structures as small as about one-quarter the size of a proton. At the smallest scales, they saw a surprising drop in J/ψ production that conventional “nuclear shadowing” struggles to explain.

Scientists have discovered that Mercury’s surface contains far less silicon dioxide than previously thought, pointing to an unexpectedly hot volcanic past. The finding suggests ancient lava may have originated from deeper, more extensively melted parts of the planet’s mantle.

Scientists discovered that charged water droplets can damage protective coatings by releasing tiny electrical discharges when they hit a surface. The hidden effect could help explain weathering and lead to tougher coatings for cars, bridges, buildings, and more.

Astronomers have detected an exceptionally faint hydrogen radio signal from billions of light-years away using South Africa’s MeerKAT telescope. Instead of finding galaxies one at a time, the technique measures their combined hydrogen glow across enormous stretches of space. The successful detection shows that astronomers may soon be able to create much larger 3D maps of the Universe.

A more realistic quantum model has revealed evidence that strange, nearly immobile quasiparticles called fractons could exist in solid materials. Their inability to move freely could make them promising building blocks for unusually robust quantum information storage.

Princeton researchers have tested an AI system that can monitor and control fusion plasma in milliseconds, reacting far faster than a human operator. In one experiment, it predicted a damaging instability about 200 milliseconds before it appeared and adjusted the plasma to stop it from forming.

Scientists used Earth’s magnetic field and atmosphere as a planet-sized detector to search for some of the lightest proposed forms of dark matter. The approach dramatically improved limits on ultralight axions and uncovered several intriguing dark photon signals that still need to be explained.
