The Anthropocene is defined by marked acceleration in human-induced perturbations to the Earth system. Anthropogenic emissions of CO and other greenhouse gases to the atmosphere and attendant changes to the global carbon cycle are among the most profound and pervasive of these perturbations. Determining the magnitude, nature and pace of these carbon cycle changes is crucial for understanding the future climate that ecosystems and humanity will experience and need to respond to. This special issue illustrates the value of radiocarbon as a tool to shed important light on the nature, magnitude and pace of carbon cycle change. This article is part of the Theo Murphy meeting issue 'Radiocarbon in the Anthropocene'.

Oleaginous filamentous fungus Mucor circinelloides harbors a GATA transcription activator AreA, which regulates nitrogen metabolism. In our previous study, deletion of AreA resulted in increased lipid production, while its overexpression reduced lipid synthesis. Although it is not a direct lipogenesis regulator, AreA influences metabolic flux by modulating nitrogen utilization pathways, which in turn affects carbon distribution.

Neonicotinoid insecticides have been identified as significant contributors to the decline of pollinators. To evaluate potential exposure of pollinators to neonicotinoids in South Korea, 79 honey samples and 27 pollen samples were obtained from agricultural, mountain, and urban areas. These samples were analyzed for 17 compounds, including neonicotinoids and their metabolites using liquid chromatography coupled with mass spectrometry.

This study explores the role of α-Fe₂O₃ in improving extracellular electron transfer (EET) and symbiotic interactions between electroactive Shewanella oneidensis MR-1, its gene-deficient mutants (ΔmtrC, ΔomcA, and ΔcymA), and microalgae (Chlorella vulgaris). The iron oxide facilitates the efficient transfer of electrons generated by MR-1 to microalgal photosystem via the pathway of CymA-MtrC-OmcA to α-Fe₂O₃. This process enhances the removals of TOC, TN, and NH₄⁺-N in the MR-1 bacterial-algal consortium by 9.

This study investigated the effects of five representative biocarriers-biochar (BC), activated carbon (AC), nano-magnetite (NM), zero-valent iron (ZVI), and polyurethane sponge (PUS)-on chain elongation (CE) from ethanol/acetate in anaerobic systems. All carriers enhanced CE to varying extents. BC and NM significantly increased caproate yields (6032.

Catalysts for heterogeneous advanced oxidation processes (AOPs) in water remediation face environmental sustainability challenges, due to the intensive production of catalysts and limited stability of catalysts while maintaining high efficiency. Herein, we design a biomimetic carbon catalyst (BCC) inspired by the diatom frustule valve structure, achieving high environmental sustainability while maintaining superior water decontamination performance by a non-radical direct electron transfer (DET) pathway through activating peracetic acid (PAA). Utilizing a hydrogen-bonding strategy, BCC features pillared layered hierarchical pores with an ultrahigh specific surface area of 2710.
