This is an announcement for the paper "Renormings of the dual of James tree spaces" by Antonio Aviles. Abstract: We discuss renorming properties of the dual of a James tree space JT. We present examples of weakly Lindelof determined JT such that JT* admits neither strictly convex nor Kadec renorming and of weakly compactly generated JT such that JT* does not admit Kadec renorming although it is strictly convexifiable.
