    Particle Physics

    Protons’ antimatter is even more lopsided than we thought

    The SeaQuest experiment finds that down antiquarks within the proton are more prevalent than up antiquarks.

    Particle Physics

    An unexpected result from a dark matter experiment may signal new particles

    An excess of events spotted in the XENON1T experiment could be signs of solar axions or weird, new properties of neutrinos, but not dark matter itself.

    Measuring the neutron’s lifetime from space could solve an enduring mystery

    Measurements on Earth show that lone neutrons decay after about 15 minutes, and now scientists have measured that lifetime from space.

    A controversial X-ray glow didn’t show up in the Milky Way’s dark matter halo

    A new look at old data suggests that an odd X-ray glow that emanates from some galaxies cannot come from decaying dark matter.
