some proposals (like fruitchain) prevent mining pools. Still it doesn't solve everything.
It would be awesome if useful PoW was the default.

I couldnt find much easily available info on fruitchain, I wonder if it could work for PoS too; a few staking pools are popping up now and its bad news in my view.

fruitchain is a research paper so there is not much presentations: https://eprint.iacr.org/2016/916. Maybe there are more research like that but I haven't seen much yet.

Now I am wondering, do we want to make pools better or do we want to totally avoid them?? I don't have a definitive idea at this point.
