Scientists found that a tiny atomic structure that forms on nickel oxide during methane conversion is more effective than the metallic nickel long believed to drive the reaction. The discovery allowed a low-nickel catalyst to rival one containing 10 ...

A new analysis of more than 1,700 supernovae is questioning whether the universe is really accelerating at all. After accounting for the ages of the stars that produce these explosions, researchers found signs that cosmic expansion may actually be .. ...

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 ...

Physicists have directly observed a long-predicted quantum effect of gravity, putting one of Einstein's foundational ideas to a striking new test. Using ultracold atoms, researchers split an atom's quantum wave so that one part was held in place ...

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 .. ...

Scientists have devised a new way to switch magnetic computer memory while using far less energy than today's leading technologies. By mathematically optimizing the pulses used to flip digital bits, the method could reduce energy consumption by ...

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 ...

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 .. ...

Scientists have uncovered an unusual form of electron behavior in zirconium pentatelluride, a quantum material that can act as both an insulator and a conductor. Under temperatures near absolute zero and magnetic fields reaching 60 tesla, electrons . ...

Harvard researchers have transformed ordinary knitting into a platform for creating fabrics that can snap between different shapes and perform useful functions. Using elastic yarns and industrial knitting techniques, the team engineered thick ...
