Ultracold dipolar gases of atoms and molecules are one of the hottest areas in AMO physics today, with promising new directions and exciting applications for novel quantum phase transitions, precision measurement, and quantum information science. In this talk I will provide a brief introduction to this field and describe our work on the many body properties of dipolar Bose-Einstein condensates and degenerate Fermi gases. I will show how the long range and non-isotropic dipole-dipole interactions give rise to novel effects such as new "blood-cell" structure of the ground state, roton feature in the excitation spectrum, local instabilities, spontaneous dynamical breaking of symmetry, and non isotropic speed of sound, with intimate relation to phenomena in superfluid He-4 and He-3.
