Summary
Homochirality origin of life takes a chemical step forward: a new Astrobiology study finds amino acid amides not only preferentially build left-handed peptide chains but amplify that preference with every residue added, while a racemic prebiotic environment may block early peptide synthesis entirely, suggesting life needed a chiral kickstart.
