All biological amino acids on Earth appear exclusively in their left-handed form, but the reason for this is elusive.
Recently, scientists uncovered new clues about the cosmic origin of this asymmetry.
That the precursors to the biological amino acids may have determined the amino acid chirality during the early phase of galactic evolution.
