  The nuclear physics landscape has been redesigned as a sequence of effective
field theories (EFTs) connected to the Standard Model through symmetries and
lattice simulations of Quantum Chromodynamics (QCD). EFTs in this sequence are
expansions around different low-energy limits of QCD, each with its own
characteristics, scales, and ranges of applicability regarding energy and
number of nucleons. We review each of the three main nuclear EFTs -- Chiral,
Pionless, Halo/Cluster -- highlighting their similarities, differences, and
connections. In doing so, we survey the structural properties and reactions of
nuclei that have been derived from the ab initio solution of the few- and
many-body problem built upon EFT input.
