<p>Nature Communications, Published online: 23 February 2026; <a href="https://www.nature.com/articles/s41467-026-69575-x">doi:10.1038/s41467-026-69575-x</a></p>Bioorganic molecules, such as amino acids, nucleobases, and sugars, are widely distributed in space. Here, the authors investigated solid-state condensation reactions of these prebiotic organic molecules under the combined effects of ionizing radiation and forsterite on the Chinese Space Station, and showed that cumulative low-dose ionizing radiation can trigger dipeptide formations and phosphorylation of ribose.
