I know there is nothing around, that I could find. I checked his tweeter and page and found nothing. So, do any of you know of anything ?
It has been known for many years that there is no embedding of the standard model into E8 (http://arxiv.org/abs/0905.2658). This is a mathematical, group-theoretical fact, which Garrett Lisi has made a career out of obscuring. His would-be theory is also precisely the kind of word-level-idea that is ruled out by the no-go theorem of Coleman and Mandula.
Several bits of good news here! I'm looking forward to the paper currently in progress.Hi MTd2, thanks for asking. A year or so ago I figured out how to generalize Cartan geometry and make sense of the idea of a deforming Lie group. It's turned out to be a very powerful and succinct geometric structure for modeling both GR and the SM, and I've been working on a paper. I gave some more hints about it on the interview jedishrfu linked. I also bought a house here in Maui, built some guest cabins, and have been running it as a micro-science institute, which has been great fun.
In the blog of the interview, you mention 10 dimensions. Isn't that a bit like string theory?Hi MTd2, thanks for asking.

oh great thanks for letting me knowRoberto, there is already a discussion thread about exactly this paper, jut look down the "Beyond" forum menu and you will see it.
MTd2 started it yesterday:

Garrett and Demystifier and others have already been conversing in that other thread.
