Two issues in hypernuclear physics, highlighted by recent experiments at the Brookhaven AGS, are discussed: (i) the nature and systematics of ..lambda.. single-particle levels revealed in (..pi../sup +/, K/sup +/) spectra on several nuclear targets from /sup 9/Be to /sup 89/Y, particularly for the 1 s/sub ..lambda../ ground-state configuration where Pauli repulsion effects arising from quark deconfinement have been conjectured; and (ii) the spin-isospin dependence of the nonmesonic weak decay ..lambda..N ..-->.. NN as extracted from partial decay rates measured for /sup 5//sub ..lambda../He and /sup 12//sub ..lambda../C, a dependence which has defied so far any explanation, perhaps due to its extreme sensitivity to short-range behavior. Additional issues bearing on future directions in hypernuclear physics, such as the spin dependence of the ..lambda..-nuclear interaction, the interpretation of ..sigma..-hypernuclear spectra and (strangeness) S = -2 physics, are only briefly mentioned.
