The PF home page has some news items in the righthand margin and one is about this:
http://arxiv.org/abs/1404.1801
The popular news account is this BBC piece:
http://www.bbc.com/news/science-environment-26329320
"They find that some three billion years after the Big Bang, the cosmos was pushing itself apart by another 1% every 44 million years.
It is the latest result to come from the Baryon Oscillation Spectroscopic Survey (BOSS).
...
...
What is interesting about the new result is that the BOSS-measured expansion rate 10 billion years ago is quite a bit slower than that expected from the standard model of cosmology.
"This is the most precise measurement that's ever been done, and all I'll say at the moment is that there is a tension there," explained Dr Matthew Pieri, a BOSS team-member from Portsmouth University, UK."
