Astrophysicist Frank Shu '63, who is credited with making pivotal contributions to our understanding of galaxies and star formation, has died at the age of 79, reports Douglas Lin and Fred Adams for Nature. “For the past dozen years, his concern about the climate crisis led him to study the use of molten-salt reactors to generate energy from nuclear waste and to convert waste biomass into inert products that can be sequestered, removing carbon from the atmosphere,” write Lin and Adams.
