Anomalies and Mysteries — Part 3: The LSND/MiniBooNE saga
A short-baseline excess seen at Los Alamos in 1995 spawned three decades of follow-up. MiniBooNE confirmed it. MicroBooNE has begun to constrain it. The mystery is not yet resolved.

Open Questions — Part 5: Are there sterile neutrinos?
A fourth (or fifth, or sixth) neutrino flavor that doesn't feel any Standard Model force? Sterile neutrinos have been hinted at for decades. Whether they actually exist — at what mass — remains open.
MicroBooNE: the experiment that may have ruled out the sterile neutrino
For thirty years, two anomalies hinted at a fourth, sterile neutrino. In 2021–2022, the MicroBooNE detector at Fermilab examined the most likely interpretation — and found nothing. The sterile neutrino story is now more confusing, not less.
Sterile neutrinos: physics's most stubborn maybe
For thirty years, a handful of experiments have hinted at a fourth, hidden type of neutrino. A handful of others insist there is nothing there. The story refuses to end.
