On the Cover

Map of microwave $B$-mode polarization for a patch of sky measured by the BICEP2 collaboration. The color represents the magnitude of fluctuations on the scale of $\pm 0.3\mu$K and the lines display the magnitude and direction of linear polarization.

EDITORIALS AND ANNOUNCEMENTS

Editorial: Signals from the Dawn of Time?

Phys. Rev. Lett. 112, 240001 (2014) - Published 19 June, 2014

We are publishing an extraordinary Letter, whose results, if confirmed, may be due to primordial gravitational waves. Because of this, we decided to allow the length and style of the paper to differ significantly from the PRL norm.
