Physicists Observe Branched Flow of Light Physicists from the Technion-Israel Institute of Technology and the University of Central Florida have experimentally observed optical branched flow in liquid soap films. Branched flow pattern shown on top of the interference color pattern generated by weak white light, making it possible to observe …

Physicists Create New Isotope of Mendelevium In an experiment performed at Lawrence Berkeley National Laboratory’s 88-inch cyclotron, a team of physicists successfully created a new isotope of the human-made element mendelevium.

Physicists Verify Half-Century-Old Theory about Physicists from the University of Glasgow and the University of Arizona have experimentally verified a half-century-old theory that began as speculation about how an advanced alien civilization could use a rotating black hole to generate energy. An artist’s impression of a rotating black hole. Image …

Researchers Develop World’s Smallest Molecular Motor A molecular motor developed by a team of researchers from Switzerland consists of just 16 atoms. The world’s smallest molecular motor consists of a single acetylene rotor anchored to a chiral atomic cluster provided by a palladium-gallium surface that acts as a stator. Image …

CERN Plans New Particle Collider 30 Times More Powerful Than LHC The Large Hadron Collider is the most advanced and complex machine ever built by humanity, and it’s allowed us to study the inner workings of the universe in unprecedented ways. However, there’s only so much you can do with …

Physicists Find Strong Evidence of Four-Top Quark Production Physicists from the ATLAS Collaboration CERN’s Large Hadron Collider have uncovered strong evidence of the production of four top quarks. This rare process is expected to occur only once for every 70,000 pairs of top quarks created at the Large Hadron Collider. …

Researchers Confirm Existence of Elusive Phase of Liquid Crystals A team of scientists from the University of Colorado Boulder and the University of Utah has confirmed the existence of a ferroelectric nematic phase of liquid crystal first proposed more than 100 years ago. View of a new phase of liquid …

Experiments with Tritium and Helium-3 Reveal New Questions in Understanding of Nuclear Structure Physicists from the Jefferson Lab Hall A Tritium Collaboration have compared the nuclei of helium and hydrogen isotopes to each other to get a clearer view of how the components of the nuclei are arranged and found …
