How We Know Neutrinos Have Mass
A hundred trillion neutrinos pass through your body every second and never touch you, and for most of the twentieth century physicists were sure they weighed nothing at all. They…

Neutrino Mass Ordering Explained: How JUNO Tells Normal from Inverted
In 59 days of running, JUNO caught 2,379 antineutrinos and pinned down two oscillation parameters 1.6 times more precisely than every previous experiment combined. It was not built for either…

Why Nobody Has Ever Seen a Free Quark
Take a proton and try to pull one of its quarks out. The force resisting you does not weaken with distance the way gravity or electricity does. It stays roughly…

Is X(2370) a Glueball? What the Missing Decay Shows
BESIII’s missing K*(892) decay signal supports a flavour-singlet argument for X(2370). It does not uniquely label the state as a glueball. The limit’s scope, production models and an exploratory hybrid…

The Nuclear Reaction That Wasn’t Breaking the Stardust Models
The first ever measurement of neutron capture on niobium-94 came back close to the theoretical estimate it replaced. That is the key finding. For two decades, stellar models struggled to…

Oxygen and Neon Collisions Reveal New Evidence of Quark-Gluon Plasma at the LHC
Two oxygen nuclei carry sixteen protons and neutrons apiece. Smash them together and the jets that come out lose energy on the way, which means something hot and dense sat…

Watching Mass Form in Real Time: How Quantum Chips Are Simulating Particle Physics
Between early 2025 and mid-2026, quantum processors have gone from simulating toy models of particle physics to watching confinement, string breaking, and hadron scattering play out in real time. These…
Analysis
The fourth neutrino was excluded at 99.99%. The anomalies are still there.
A fourth neutrino that feels no weak force explained thirty years of anomalies. MicroBooNE excluded it at 95% confidence and KATRIN found no kink in 36 million electrons. The eV-scale…

Six antineutrinos a day, measured from a reactor that had been switched off for weeks
A pressurised water reactor that has been offline for three weeks still sends about six antineutrino events a day into a detector 400 metres away. Double Chooz has measured that…

X(2370) Glueball Candidate: What BESIII Measured
BESIII has measured X(2370) in several decay channels and established its pseudoscalar quantum numbers. A newer combined analysis gives a mass near 2.36 GeV/c². These results support the glueball investigation,…
