Poor wastewater management drives both pollution and rising antimicrobial resistance (AMR). A molecular-level analysis reveals that hydrogen sulfide accelerates plasmid-driven transfer of AMR genes in water.

Combining carbon dioxide (CO₂) electrolysis with biological denitrification provides an integrated approach for carbon utilization and wastewater treatment, where formate produced from the electrochemical reduction of CO₂ is directly used as a carbon source for wastewater denitrification.

The time points beyond which individual Antarctic ice shelves could no longer exist in their current form have been estimated under several anthropogenic emission scenarios. These projections take into account uncertainties related to ice, atmosphere and ocean processes, including those concerning poorly understood processes such as ice fracturing and iceberg formation.

While the need to transform food and agriculture through a systemic approach may seem obvious, how to do it given siloed policies and structures is unclear. Corinna Hawkes, Director of the Division of Food Systems and Food Safety for the UN Food and Agriculture Organization, builds on real-world examples to show that overcoming these barriers is possible where there is focus and intention.

Cellular agriculture is emerging as a new approach to the production of food ingredients, offering an alternative to conventional agricultural practices. This Comment highlights critical sustainability considerations and examines the energy efficiency of biotechnologically produced cellular crops.
