  A recent RIKEN experiment on the quenched $g_A$ in the superallowed
Gamow-Telller transition from $^{100}$Sn indicates a role of scale anomaly
encoded in the anomalous dimension $\beta^\prime$ of the gluonic stress tensor
${\rm Tr \ G}_{\mu\nu}^2$. This observation provides a support to the notion of
hidden scale symmetry emerging by strong nuclear correlations with an IR fixed
point realized -- in the chiral limit -- in the Nambu-Goldstone mode. We
suggest there is an analogy in the way scale symmetry manifests in nuclear
medium to the continuity from the unitarity limit at low density (in light
nuclei) to the dilaton limit at high density (in compact stars). In between the
limits, say, at normal nuclear matter density, the symmetry is not visible,
hence hidden.
