Since the publication of the LSND measurements of neutrino oscillations, light sterile neutrinos with a mass around 1 eV have been claimed to represent a possible solution to the so-called short-baseline oscillation anomalies. The existence of one additional neutrino has been tested at a variety of different experiments: accelerator, atmospheric and reactor neutrino experiments, direct neutrino mass measurements, cosmological studies, and more. In this seminar, we will review the most important observations in favor of and the strongest constraints against the existence of such a new particle, with particular attention to the tensions between different experimental results. We also briefly discuss the importance of sterile neutrinos at different mass scales.
