After a decade of painstaking measurements, scientists have delivered a major plot twist in particle physics: a ...

Scientists have taken a major step toward solving a long-standing mystery in particle physics, by finding no sign of the particle many hoped would explain it.

A decade-long investigation into puzzling neutrino behavior has now ruled out one of the most widely discussed explanations: ...

Scientists search for "decaying" dark matter (DDM) because it offers unique signatures like specific X-ray or gamma-ray lines ...

After a decade at Fermilab, scientists found no evidence for the sterile neutrino. MicroBooNE ruled it out with 95% certainty ...

Two papers challenged the existence of theorized particles called sterile neutrinos that might account for mysteries like the cosmos’s dark matter.

Learn how a particle born in the sun’s core left a measurable flash of light two kilometers beneath Earth’s surface.

A deep-sea neutrino telescope has detected the most energetic neutrino ever recorded. The particle, known as a "ghost particle," was about 30 times more active than the previous record-holder.
