From Physics Today, June 14, 2018: New results from MiniBooNE confirm tantalizing evidence from 20 years ago of an additional neutrino species, but they also fly in the face of findings from other recent experiments.

From Scientific American, June 7, 2018: Physicists have caught ghostly particles called neutrinos misbehaving at Fermilab’s MiniBooNE experiment, suggesting an extra species of neutrino exists.

Some scientists spend decades trying to catch a glimpse of a rare process. But with good experimental design and a lot of luck, they often need only a handful of signals to make a discovery.
