Active-sterile {\em oscillations} can be directly observed in the granular LENS detector itself to critically test and extend results of short baseline accelerator and reactor experiments.Submitted to the proceedings of the XII International Workshop on Neutrino Telescopes, March 6-9, 2007, VeniceHigh Energy Physics - ExperimentNuclear Experimenttext
