Apparently, it's looking as if the BICEP team might have made a mistake in estimating their foregrounds (galactic dust), which would invalidate their claim to have detected primordial B-modes (one of the biggest physics discoveries of this century). The rumour is that they misunderstood an image taken from a conference talk. This will be very disappointing if true!
Once you correct for that and rescale the Planck results appropriately, some experts claim that the polarized galactic dust emission can account for most of the BICEP signal. The rumor is that the BICEP team has now admitted to the mistake.
