• 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.
• Physicists just saw quarks make waves in the Big Bang’s primordial soup
  Physicists at CERN’s Large Hadron Collider have captured the clearest evidence yet that quark-gluon plasma, the scorching-hot matter that filled the newborn universe, behaves like a true liquid. By tracking individual quarks as they blasted through the plasma, researchers saw them leave behind ripples, splashes, and swirling wakes much like a duck moving through water. The finding suggests this primordial “soup” is so dense that it can slow speeding quarks and respond collectively as a fluid.
