title: Feeling our way in the dark.
abstract: The papers by Pontecorvo et al., Kesner and Altman and Normile are considered with regard to their illuminating potential in an area dark and murky with research issues. While each of these papers contributes an interesting perspective and narrow beam of light, the collective darkness dissipated by their work remains small.
