  • Scientists who discovered a third form of magnetism win major physics prize
    Physicists have uncovered a hidden third form of magnetism that challenges more than 100 years of established physics. Called altermagnetism, the discovery could transform future computing and electronics while opening an entirely new frontier in quantum research.
  • Physicists just found the ‘ghost’ of superconductivity
    Physicists have found striking evidence for an unusual form of superconducting behavior in uranium ditelluride, where electron pairs organize into rippling patterns called pair density waves. Even more surprisingly, these patterns appear to survive after ordinary superconductivity disappears, suggesting that the electron pairs responsible for superconductivity may begin forming before the material actually becomes superconducting.
  • Scientists finally see how nature moves energy so efficiently
    Researchers have captured key steps in a chemical reaction that helps nature transfer energy with remarkable efficiency. Ultrafast X-rays revealed how changes involving electrons and protons are closely linked to the rearrangement of surrounding water molecules. Because similar reactions drive photosynthesis and other energy-conversion processes, the technique could help scientists develop better catalysts, fuel cells, […]
  • A new kind of magnetism could unlock faster, more efficient computers
    Scientists have discovered evidence of altermagnetism in a thin, highly tunable material that could help electronics use electron spin instead of relying only on electrical charge. The unusual magnetic state may enable faster, more energy-efficient devices without the unwanted magnetic interference caused by conventional magnets.
  • A new process turns plastic waste into gasoline and diesel fuel
    Scientists at Oak Ridge National Laboratory have developed a surprisingly simple way to turn polyethylene, the common plastic used in shopping bags and cutting boards, into gasoline and diesel-like fuels. The process uses inexpensive aluminum-based molten salts to break long plastic molecules into smaller hydrocarbons, producing about 60% gasoline under relatively mild conditions.
  • Billions in rare earth elements may be hiding in America’s coal ash
    Scientists are looking to diatoms, sea sponges, and plants for a cleaner way to recover rare earth elements and other valuable minerals hidden inside coal ash, red mud, and mine tailings. The bio-inspired approach could turn massive industrial waste piles into useful materials while reducing energy use, harsh chemicals, and reliance on new mining.
