Query: Sterile-active neutrino oscillations and shortcuts in the extra
  dimension   We discuss a possible new resonance in active-sterile neutrino oscillations
arising in theories with large extra dimensions. Fluctuations in the brane
effectively increase the path-length of active neutrinos relative to the
path-length of sterile neutrinos through the extra-dimensional bulk. Well below
the resonance, the standard oscillation formulas apply. Well above the
resonance, active-sterile oscillations are suppressed. We show that a resonance
energy in the range of 30-400 MeV allows an explanation of all neutrino
oscillation data, including LSND data, in a consistent four-neutrino model. A
high resonance energy implies an enhanced signal in MiniBooNE. A low resonance
energy implies a distorted energy spectrum in LSND, and an enhanced v_mu
depletion from a stopped-pion source. The numerical value of the resonance
energy may be related back to the geometric aspects of the brane world. Some
astrophysical and cosmological consequences of the brane-bulk resonance are
briefly sketched.
