A review of the latest measurements of the primordial abundances of the light nuclei D, He, He and Li is given. We discuss in particular the primordial abundance Yp of He as measured in blue compact dwarf galaxies. We argue that the best measurements now give a “high” value of Yp along with a “low” value of D/H, and that the two independent measurements are consistent within the framework of st...

The paper " Big Bang Nucleosynthesis and Active-Sterile Neutrino Mixing: Evidence for Maximal ν µ ↔ ν τ Mixing in Super Kamiokande? " by X. Shi and G. M. Fuller (astro-ph/9810075) discusses the cosmological implications of the ν µ → ν s solution to the atmospheric neutrino anomaly. It incorrectly concludes that a lower bound on the ν τ mass of 15 eV is needed in order for the ν µ → ν s oscillat...
