Well, somewhat. Now it's in the form of Higgs field. Unlike ether, Higgs field does not interact with uniformly moving particles, only those that are accelerating.
Here's a great book I just recently listened: http://www.amazon.com/The-Black-Hole-War-Mechanics/dp/031601...
It's by Leonard Susskind from Stanford. The thoughts experiments in the book are just terrific. Loved it.
