gravitational waves from extra dimensions

Lisa Randall (Harvard) gave a nice talk pointing out (and calculating in detail) the fact that some of the generic large extra dimensions theories (in particular Randall-Sundrum 1) have a first-order phase transition at the weak scale and that such theories in general produce gravitational radiation in the LISA bandpass, at LISA-sensitivity levels. So we might discover extra dimensions or other non-trivial properties of the dark sector with LISA. Not bad!
