CERN has started replacing some of the Large Hadron Collider's most important magnets as part of its High-Luminosity upgrade. The new superconducting magnets will produce fields about 40% stronger, allowing particle beams to be squeezed more tightly ...

Researchers have shown that exotic quantum particles called non-Abelian anyons can perform the full range of operations needed for universal quantum computing. Using 54 qubits on Quantinuum's H2 processor, they combined braiding and fusion to unlock ...

A dead white dwarf with no detectable disk has somehow produced a powerful shock wave that appears to have persisted for at least 1,000 years. Its magnetic field may be partly responsible, but astronomers say an unexplained "mystery engine" may also ...

Ancient grains inside one of the oldest known meteorites reveal that a surprisingly strong magnetic field existed during the solar system's first 200,000 years. The discovery suggests magnetism worked alongside gravity to help transform a vast cloud ...

Researchers have shown that multiple time crystals inside a semiconductor can synchronize their oscillations, much like pendulum clocks gradually falling into the same rhythm. The coupling is carried by spin-polarized electrons, allowing time ...

Ariel, one of Uranus' moons, may once have contained a subsurface ocean more than 100 miles deep beneath its fractured icy shell. The finding, combined with similar evidence from Miranda, suggests the distant Uranian system could harbor multiple ...

Hubble observations of massive stars in metal-poor dwarf galaxies are revealing clues to why the early universe looks so unusual. Researchers found that stellar winds weaken sharply at extremely low metallicities, potentially allowing massive stars . ...

Astronomers have discovered the first globular cluster stellar stream beyond the Milky Way, opening a new way to study dark matter in distant galaxies. These faint trails of stars trace a galaxy's gravitational structure and could eventually help ...

Physicists searching through Large Hadron Collider data found no evidence that the machine has been producing microscopic quantum black holes, but the result sharply narrows where such exotic physics could still be hiding. These hypothetical black .. ...

Ancient iron meteorites reveal that some of the Solar System's first solid bodies were built mostly from tiny heat-forged rock beads called chondrules, while water-rich dust was largely excluded. The finding pushes this selective planet-building ...
