Detectors inside the MiniBooNE tank captured an excess of electron neutrinos—a possible sign that sterile neutrinos exist.

Don't toss out your particle physics textbooks just yet. Last Friday, a team of particle physicists announced results that could point to an exotic new particle called a sterile neutrino, triggering a cascade of feverish headlines. But the situation is more ambiguous than some reports suggest. Although the new data bolster one argument for the sterile neutrino, other evidence has weakened significantly in recent years.
