I just got back from the Marseille conference on loop quantum gravity and spin foams:
http://w3.lpm.univ-montp2.fr/~philippe/quantumgravitywebsite/
It was really great, so I devoted "week206" of my column This Week's Finds entirely to this conference:
http://math.ucr.edu/home/baez/week206.html
In particular, I spend a lot of time giving a very simple nontechnical introduction to the recent work of Ambjorn, Jurkiewicz and Loll in which they seem to get a 4d spacetime to emerge from a discrete quantum model - something that nobody had succeeded in doing before!

I hope this lays to rest certain rumors here that I'd burnt out on quantum gravity.![Devil :devil: :devil:](https://www.physicsforums.com/styles/physicsforums/xenforo/smilies/oldschool/devil.gif)
