Soil carbon content is positively related with plant diversity in global grasslands, and this relationship is particularly strong in warm and arid climates. Plant diversity is related to soil carbon via the quality of organic matter.

Oxidative catalytic depolymerization of polystyrene (PS) can produce benzoic acid, but the annual consumption of benzoic acid is ~40 times lower than PS, so benzoic acid should be converted to higher-volume chemicals for the process to be viable. Here, the authors report a hybrid chemical and biological process that uses PS as feedstock for production of adipic acid, a high-volume co-monomer for nylon 6,6, via benzoic acid.

Engineering of local Anopheles gambiae under containment enables the generation of a transgenic strain equipped with non-autonomous gene drive capabilities that robustly inhibits genetically diverse Plasmodium falciparum isolates obtained from naturally infected children.

Ji and colleagues show that the specific angiosperm growth-governing DELLA–SLY1/GID2 protein interaction evolved from a broader ancestral affinity, suggesting affinity narrowing to be a general evolutionary driver of interaction specificity.

Ecological effects, such as disturbances, have a spatial dimension, but what influences their spatial propagation is not fully understood. Here, the authors find generalist and widespread species are key to propagating effects spatially, mediated by landscape characteristics and species provenance.

It is unclear whether plant-herbivore interactions systematically favour exotic plant species. Here the authors investigate plant-herbivore and plant-soil biota interactions in experimental mesocosm communities, finding that exotic plants dominate community biomass despite accumulating more invertebrate herbivores.

Field photographs are essential for research and conservation, but are difficult to access since there is no central database or connection between archives. The 25 leading databases hold only 53% of the plant species of the Americas, illustrating the need for increased work on collecting and standardizing this valuable data.

Experimental and computational analyses indicated that positively charged nanoparticles experience pH- and lipid-coating-dependent transformations in plants that modify their impact on RuBisCO photosynthetic protein corona formation and function.

This work introduces a wireless, battery-free soil sensor that enables subsoil monitoring of moisture and salinity using drone-readable signals. The system allows scalable, low-cost deployment across farms, helping improve agricultural efficiency and sustainability.

Transition from coal to gas, retrofitting and retirement of coal power plants are expected to reduce air pollution and therefore have positive health effects. Casey et al. present direct evidence of this phenomenon by reporting improved asthma outcomes in the wake of coal plant closure and retrofit in Louisville, Kentucky.

FLS2 is the well-known plasma membrane receptor for flg22, a specific region of bacterial flagellin. But Solanaceae can also detect flagellin through another epitope, flgII-28, thanks to the novel receptor-like kinase FLS3 now identified in tomato.

Oat is an important food crop, but the genetic diversity within the gene pool remains unclear. Here, the authors report the analyses of worldwide diversity and population structure of hexaploid oat, and identify signatures of structural rearrangements within the germplasm collection.

Species interaction data, a field experiment and modelling of plant–insect communities show that landscapes with more habitat types support more even species, more complementary interactions, are more consistently robust to species loss, and confer greater pollination function.

This study projects the private costs and monetized climate and health damages of electrifying long-haul heavy-duty diesel trucks. Battery electric trucks yield net positive societal benefits by 2035, contingent on policies that accelerate adoption.
