DESCRIPTION:In this talk I will introduce some transport properties of 3D 
 topological insulators. The locking between spin and momentum direction ca
 n provide a large and linear magnetoresistance and can create a spin polar
 ization due to charge current. I will then outline why new electronic phas
 es emerge at the interface with superconductors. Our experimental efforts 
 have concentrated on inducing superconductivity into Bi based 3D topologic
 al insulators by the proximity effect from superconducting Nb. Josephson j
 unctions and superconducting quantum interference devices have been realiz
 ed that provide insight into the prospects of using TI-S hybrids towards M
 ajorana detection and topological quantum computation.
