Constraint on the primordial gravitational waves from the joint analysis of BICEP2 and Planck HFI 353 GHz dust polarization data
It seems that the contamination of the BICEP2 signal by B Mode polarised light from galactic dust lanes might explain all the polarisation detected. I was at a lecture the other night by Professor Jo Dunkley of Oxford University who is working on the problem. She is now working on a balloon experiment to be launched in two years time to see if there is an Inflation Gravity Wave signal hidden behind the dust signal detected by BICEP2.
In any case the BICEP2 team's announcement in March that they had 'detected Inflation' seems embarrassingly premature given that they did so before their paper had been peer reviewed and published.

We make a joint analysis of BICEP2 and recently released Planck HFI 353 GHz dust polarization data, and find that there is no evidence for the primordial gravitational waves
