    In a first, scientists took the temperature of a sonic black hole

    Taking a black hole’s temperature is a seemingly impossible task. But now, physicists report the next best thing. They’ve measured the temperature of a lab-made sonic black hole, which traps sound instead of light.

    If the result holds up, it will confirm a prediction of cosmologist Stephen Hawking, who first proposed a surprising truth about black holes: They aren’t truly black. Instead...

    Physicists wrangled electrons into a quantum fractal

    Physicists have created an oddity known as a quantum fractal, a structure that could reveal new and strange types of electron behaviors.

    Fractals are patterns that repeat themselves on different length scales:  Zoom in and the structure looks the same as it does from afar. They’re common in the natural world. For instance, a cauliflower stalk looks like a miniature version of the full...

    Bizarre metals may help unlock mysteries of how Earth’s magnetic field forms

    Weird materials called Weyl metals might reveal the secrets of how Earth gets its magnetic field.

    The substances could generate a dynamo effect, the process by which a swirling, electrically conductive material creates a magnetic field, a team of scientists reports in the Oct. 26 Physical Review Letters.

    Dynamos are common in the universe, producing the magnetic fields of the Earth...

    A new hydrogen-rich compound may be a record-breaking superconductor

    Superconductors are heating up, and a world record-holder may have just been dethroned.

    Two studies report evidence of superconductivity — the transmission of electricity without resistance — at temperatures higher than seen before. The effect appears in compounds of lanthanum and hydrogen squeezed to extremely high pressures.

    All known superconductors must be chilled to function,...

    Strange metals are even weirder than scientists thought

    Curiouser and curiouser: Strange metals are getting a little stranger.

    Normal metals such as copper and aluminum are old hat — physicists have a strong grasp on the behavior of the electrons within. But strange metals behave in mysterious ways, and researchers have now uncovered an additional oddity. A type of strange metal called a cuprate behaves unexpectedly when inside a strong...

    ‘Time crystals’ created in two new types of materials

    It was only a matter of time.

    A weird form of matter called a time crystal has made an appearance in two more types of materials, doubling the number of known time crystal habitats. In a typical crystal, its arrangement of atoms regularly repeats in space, such as the alternating sodium and chloride ions that make up a salt crystal. But time crystals’ patterns repeat themselves at...
