  Recent measurements of the Cosmic Microwave Background Anisotropy have
provided evidence for the presence of oscillations in the angular power
spectrum. These oscillations are a wonderful confirmation of the standard
cosmological scenario and allow us to derive constraints on many cosmological,
astrophysical and inflationary parameters. If the discovery is confirmed by
future experiments, opportunities may appear, for example, to constrain dark
energy, variations in fundamental constants and neutrino physics.
