    Brian Powell [bapowell] has a new paper out - Scalar runnings and a test of slow roll from CMB distortions, http://arxiv.org/abs/1209.2024. This is interesting and challenges some of the more radical ideas that are currently popular. Very nice, Brian!

    Yes! and also thank to Chronos for spotting the paper and alerting us to it. Personally I'd be glad if anyone were to offer some intuitive explanation. The "running of running" idea...there's a lot of potentially very interesting stuff here I don't adequately understand.

    I'd also like to know if there is any way in which the observations described here might have a bearing on the most recent paper (re inflation phenomenology) by Agullo, Ashtekar, Nelson. Perhaps not, but it would be intriguing if so.
