Yet Another New State of Matter has been discovered. How many is that now? I've completely lost track. Anyway, to add to the standard list of

• Solid
• Liquid
• Gas
• Plasma
• Superliquid
• Supersolid
• Liquid Crystal
• Quasicrystal
• Bose-Einstien Condensate
• Fermi Gas
  
• and others

We now have the Efimov state, which is a sort-of quantum-mechanical ménage-a-trois.
