  I survey recent developments in hadron physics which follow from the
application of superconformal quantum mechanics and light-front holography.
This includes new insights into the physics of color confinement, chiral
symmetry, the spectroscopy and dynamics of hadrons, as well as surprising
supersymmetric relations between the masses of mesons, baryons, and
tetraquarks. I also will discuss some novel features of QCD -- such as color
transparency, hidden color, and asymmetric intrinsic heavy-quark phenomena. The
elimination of renormalization scale ambiguities and the modification of QCD
sum rules due to diffractive phenomena are also briefly reviewed.
