    Summary: Dust from asteroid Bennu is revealing a surprising origin
    story for liferCOs building blocks. New research suggests some amino
    acids formed in frozen ice exposed to radiation, not warm liquid water
    as scientists long believed. Isotopic clues show BennurCOs chemistry
    differs sharply from well-studied meteorites, pointing to multiple
    pathways for creating liferCOs ingredients.
