Recent  developments  in  new  materials,  new  high  precision  probes,  and  new  numerical  methods,  brought  us  to  an  exciting  moment  of  opportunity  in  the  high  Tc superconductivity(HTSC)  research.  The  discovery  of  Fe-­‐based  HTSC  materials  and  striking  universality  among  Cu-­‐based  and  Fe-­‐based  HTSC  materials  enabled  significant  progress  in  our understanding of essential elements of HTSC and complex phase diagram of HTSC materials.  In particular,  establishment  of  broken  symmetry  associated  with  pseudogap  phase  of  Cu-­‐based  superconductors offered firm grounds for solid theoretical progress. Further there is a growing consensus on how antiferromagnetic interactions drive unconventional superconductivity. I will discuss  exciting  latest  developments  in  these  advances  through  the  strong  theory/experiment  collaborations[1-­‐4].
