  • A simple design approach and predictive computational methods have spawned a pathway for making materials that could trap specific molecules — an ability needed for applications such as carbon capture.

  • The Strecker reaction is thought to offer a prebiotically plausible synthesis of amino acids, but is reversible at the high or low pH ranges needed to promote reactivity. Here the reaction of hydrogen cyanide and diamidophosphate is shown to provide stable phosphorylated amino acid precursors at neutral pH, which can be hydrolysed to amino acids or thiolysed to thioamides.

  • While mechanisms have been proposed for the prebiotic nucleotide synthesis, these require separate (and potentially incompatible) routes for pyrimidines and purines. Here the authors show that both of these classes of molecules can be formed by a divergent synthesis from a common prebiotic precursor.

  • Arabinonucleic acid (ANA) Watson-Crick base-pair with RNA/DNA and can evolve to display enzyme-like function. Here, the authors now identify a prebiotic pathway that yields the complete set of Watson-Crick base-pairing purine and pyrimidine ANA nucleosides.

  • 2-aminothiazole — a hybrid of prebiotic amino acid and nucleotide precursors — sequentially accumulates and purifies glycolaldehyde and glyceraldehyde from complex mixtures in the order required for ribonucleotide synthesis, dynamically resolves glyceraldehyde from its ketose-isomer dihydroxyacetone, and provides the first strategy to select natural amino acids from abiotic aldehydes and ketones.
