    Physicists spot a new class of neutrinos from the sun

    Researchers with the Borexino experiment in Italy have detected neutrinos produced in the secondary fusion process taking place in the sun’s core.

  2. 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.

  3. Particle Physics

    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.

  4. Physics

    A star shredded by a black hole may have spit out an extremely energetic neutrino

    A star’s fatal encounter with a black hole might have produced a neutrino with oomph.

  5. 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.

  6. Particle Physics

    Particles called axions could reveal how matter conquered the universe

    Axions, if they exist, may solve not one, not two, but three pressing puzzles of particle physics.

  7. Particle Physics

    Physicists have narrowed the mass range for hypothetical dark matter axions

    In two new studies, scientists search for axions within new mass ranges but the particles remain elusive.

  8. Particle Physics

    Antimatter hydrogen has the same quantum quirk as normal hydrogen

    Atoms of antihydrogen are affected by the Lamb shift, which results from transient particles appearing and disappearing.

  9. Physics

    A barrier to colliding particles called muons has been smashed

    Future particle accelerators could slam muons together to reach higher energies than any before.

  10. Particle Physics

    Misbehaving kaons could hint at the existence of new particles

    Certain extremely rare decays seem to be happening more often than expected, and scientists don’t know why.

  11. Physics

    Mounting evidence suggests neutrinos are key to why antimatter is rare

    The source of matter’s dominance over antimatter might be revealed by the tiny subatomic particles.

  12. Physics

    Physicists have found quasiparticles that mimic hypothetical dark matter axions

    These subatomic particles could make up dark matter in the cosmos. A mathematically similar phenomenon occurs in a solid material.
