In this talk I present results for UV-IR flows for fully momentum-dependent propagators, vertices in quantum gravity.  The momentum locality of the underlying block-spinning procedure is related to diffeomorphism invariance. The setting is used to compute  the scale-dependent Newton coupling and the cosmological constant. Physics implications as well as the extension to gauge-matter-gravity systems are discussed.
