  • In the scramble to achieve net-zero emissions by 2050, many nations are examining their agriculture and land-use sectors. In Ireland, while net-zero emissions by 2050 are feasible through a reduction in meat and dairy production and smart land management, carbon neutrality beyond 2050 may prove fleeting.

  • In Ireland, afforestation, organic soil re-wetting, and cattle destocking are key for meeting the net zero goal regardless of its definition; technical abatement moderates but does not substitute these actions, according to an analysis of agriculture and land use scenarios.

  • One theory for the abiogenesis of RNA involves ligation of shorter oligomers that are observed after dry-state condensation of mononucleotides. Here, the chemo- and regioselective acetylation of (oligo)nucleotides in water under prebiotically plausible conditions is described. This remarkable selectivity permits the rapid template-directed ligation of oligomers to favour extant 3′,5′-linkages.

  • A minimal cell — one that has all the minimum requirements for life — is still a complex entity comprising informational, compartment-forming and metabolic subsystems. Here it is shown that, contrary to previous assumptions, a common prebiotically plausible chemistry can give rise to building blocks for all the subsystems.
