  Recent developments of chiral effective field theory (ChEFT) applications to
nuclear and neutron matter are summarized, with special emphasis on a
(non-perturbative) extension using functional renormalisation group methods.
Topics include: nuclear thermodynamics, extrapolations to dense baryonic matter
and constraints from neutron star observables. Hyperon-nuclear interactions
derived from SU(3) will be discussed with reference to the "hyperon puzzle" in
neutron star matter.
