  • Physicists are surprised by this magnetic material that “freezes” when heated

    When disordered magnetic materials are cooled to the right temperature, something interesting happens. The spins of their atoms “freeze” and lock into place in a static pattern, exhibiting cooperative behavior that is not usually displayed. Now, for the first time, physicists have seen the opposite. When fractionally heated, the natural magnetic element neodymium freezes, subverting […]

  • Astronomers unveil the most detailed map of metallic asteroid Psyche yet

    If you wanted to do some forensic study of the solar system, you could head to the main asteroid belt between Mars and Jupiter. This is where you can find ancient rocks dating back to the early days of the solar system. Out there, in the cold vacuum of space, far from the Sun, the […]
