The neutrino’s quantum fuzziness is beginning to come into focus
Neutrinos are known for funny business. Now scientists have set a new limit on a quantum trait responsible for the subatomic particles’ quirkiness: uncertainty. The lightweight particles morph…
Scientists propose a hunt for never-before-seen ‘tauonium’ atoms
Atoms are normally made of a nucleus and electrons. But scientists are proposing a hunt for a new variety of atom without either. Tauonium (sometimes called “ditauonium” or…
Scientists just 3D printed one of the hardest metals on Earth
A new laser-based 3D printing method could make ultra-hard cutting tools with less waste and lower costs. Credit: Shutterstock Tungsten carbide-cobalt (WC-Co) is valued because it can withstand…
Dark matter experiments get a first peek at the ‘neutrino fog’
The neutrino “fog” is beginning to materialize. Lightweight subatomic particles called neutrinos have begun elbowing their way into the data of experiments not designed to spot them. Two…
The possibilities for dark matter have just shrunk — by a lot
Scientists have just slashed the potential hiding spaces for dark matter particles. The LUX-ZEPLIN, or LZ, experiment has searched for and ruled out the existence of dark matter…
The Large Hadron Collider exposes quarks’ quantum entanglement
Quantum entanglement has made its way to the top. Scientists have measured the strange quantum phenomenon of entanglement in top quarks, the heaviest fundamental subatomic particles known. It’s…
A neutrino mass mismatch could shake cosmology’s foundations
As the youthful universe congealed under the pull of gravity, matter knotted itself into galaxies, galaxy clusters and filaments, weaving a dazzlingly intricate cosmic web. This web’s structure…
Physicists just discovered the rarest particle decay ever
It’s the rarest particle decay ever discovered. Scientists have clinched the case for a special type of decay of subatomic particles called kaons. Further study of the rare…
UCLA scientists discover how to guide heat like light at room temperature
UCLA researchers have discovered that heat can be guided along precise, ray-like paths through boron arsenide at room temperature. Credit: AI/ScienceDaily.com Managing heat efficiently inside solid materials is…
A near-Earth asteroid offers clues to one dark matter theory
A hypothetical “fifth force” could tug on asteroids, if it exists. But the asteroid Bennu shows no signs that its orbit has been tweaked by such a force.…
