Release Date: 8 April 2015

A recent paper, Discrete Steps in Dispersion Measures of Fast Radio Bursts, has generated a lot of excitement. Paul Carr reviews the basic facts about the 11 known FRBs and what this strange pattern might imply.

Update: Petroff, et. al., Finding the Source of Perytons at the Parkes Radio Telescope

Further Update: Five new FRBs were recently reported.  Only one of these five (130626) has a Dispersion Measure close to a multiple of 187.5, so it could just be a fluke, but FRB 150418 was also reported, and it's DM is 776.2, which is close to 4 x 187.5.
