DESCRIPTION:Charged black holes in planar AdS can be unstable to the forma
 tion of charged scalar hair. Through holography\, one hopes to use this fa
 ct to uncover general principles governing unconventional superconductors.
  It has been shown however that the behaviour of `holographic superconduct
 ors' depends strongly on their embedding into string/M-theory. In this tal
 k I will discuss two aspects of this issue in which progress can be made. 
 First I will demonstrate how the ground states of these systems may be fou
 nd by blowing up stars in global AdS\, then I will hunt for the instabilit
 y of highest temperature in a wider consistent truncation of supergravity.
  Both aspects raise concerns that a new approach to the problem is needed.
