There’s a new measurement of muon magnetism. What it means isn’t clear
Muons might not behave as expected. But scientists can’t agree on what to expect. By taking stock of how the subatomic particles wobble in a magnetic field, physicists…
Scientists finally detected oxygen-28. Its instability surprised them
A “magic number” of physics might not be so magic after all. Using a powerful particle accelerator, researchers have spotted an elusive variant of oxygen for the first…
Scientists twist crystal layers and reshape matter from within
Scientists can now twist and bond large oxide layers with atomic precision, opening a promising new frontier for customizable electronics. Credit: Jie Sun Researchers have developed a way…
Forests might serve as enormous neutrino detectors
Neutrino detectors don’t grow on trees. Or do they? Forests could one day be used to spot ultra-high-energy neutrinos, a physicist proposes. Trees could act as natural antennas that pick…
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…
