    Particle Physics

    There’s a new measurement of muon magnetism. What it means isn’t clear

    The measurement, from the Muon g−2 experiment, is the most precise yet. But recent theoretical predictions are a bit muddled.

    Centuries on, Newton’s gravitational constant still can’t be pinned down

    A new experiment could finally answer the question 'What is the strength of gravity?' But it's a hard test to do.

    Physics

    Mass has different definitions. The moon’s orbit confirms two are equivalent

    Laser measurements of the moon’s orbit square with Newton’s third law of motion and Einstein’s theory of gravity.

    Chemistry

    Tear-resistant rubbery materials could pave the way for tougher tires

    Adding easy-to-break molecular connectors surprisingly makes materials harder to tear and could one day reduce microplastic pollution from car tires.
