  Thanks to the long-term collaborations between nuclear and astrophysics, we
have good understanding on the origin of elements in the universe, except for
the elements around Ti and some neutron-capture elements. From the comparison
between observations of nearby stars and Galactic chemical evolution models, a
rapid neutron-capture process associated with core-collapse supernovae is
required. The production of C, N, F and some minor isotopes depends on the
rotation of massive stars, and the observations of distant galaxies with ALMA
indicate rapid cosmic enrichment. It might be hard to find very metal-poor or
Population III (and dust-free) galaxies at very high redshifts even with JWST.
