I think Alain Connes, Ali Chamseddine, and Slava Mukhanov have scored a big hit with the November 2014 paper titled

I'll try to explain bit by bit what is going on with that paper, and will appreciate additional understanding and explanation others may wish to volunteer.

Connes and Chamseddine are both at Bures-sur-Yvette (basically a French "institute for advanced studies" called IHES) and Mukhanov is based in Munich. Chamseddine also has a professorship at Beirut, so you might hear of seminars on this stuff being held in Beirut.

Basically it was a "waiting for the other shoe to drop" situation. C&C seemed to pull the Standard Model particles out of some algebra, but it wasn't clear where a piece of the algebra came from. And it looked like they might be going to get quantum gravity too in a combined package. Finally, it seems, they did! and the same algebraic elements emerged. So they have a unified QG&M (quantum geometry and matter, if that makes sense). Particles and quanta of geometry turn out to grow from a common root, and be encompassed by the same algebra. Have to do something in the kitchen, back soon.
