I will discuss a supergravity solution corresponding to fivebranes wrapped on the S2 of the resolved conifold. By changing a parameter the solution continuously interpolates between the deformed conifold with flux and the resolved conifold with branes. Therefore, it displays a geometric transition, purely in the supergravity context. The solution is a simple example of torsional geometry and may be thought of as a non-Kahler analog of the conifold. I will discuss how one can obtain supersymmetric solutions of type IIB supergravity starting from simpler non-Kahler geometries, by U-dualities or other methods. Applying these transformations to the torsional conifold solution we obtain a solution dual to the baryonic branch of the Klebanov-Strassler theory. Far along the baryonic branch the solution resembles D5 branes wrapping a fuzzy two-sphere in the resolved conifold and this can be matched to a weakly coupled field theory analysis.
