New interpretation is given to the isotopic anomalies detected by Lugmair et al. in an acid-resistant residue of the Allende meteorite. If the 142Nd excess is due to 146Sm decay, as the discoverers proposed, the author argues that the decay has occurred in interstellar grains, so that the conclusion that 146Sm (1.03×108 yr) was alive in the solar system is premature. It is shown that the discovery is likely to be s-process Nd, confirming the survival of red-giant stardust in carbonaceous interstellar dust.
