Towards a Community Framework for Agent-Based Modelling [PDF]

Agent-based modelling has become an increasingly important tool for scholars studying social and social-ecological systems, but there are no community standards on describing, implementing, testing and teaching these tools.

Gut Lactate Boosts Ruminococcus via Histone Lactylation to Mediate Time‐Restricted Feeding Protection in Crohn's Disease

Advanced Science, EarlyView.
TRF enriches Ruminococcus, a bacterial genus producing SCFAs, and activates the epithelial HIF‐1α signaling pathway. This mechanism protects the colonic mucosa from inflammatory insults in colitis models. Mechanistically, gut lactate production during starvation and refeeding mediates H4K12la, which increases SLC9A3 expression and creates an acidic gut

Diversity of Pharmaceuticals Enhances Antibiotic Resistance in the Invertebrate Gut via Biofilm‐Mediated Mechanisms

Advanced Science, EarlyView.
Pharmaceutical diversity acts as an independent driver of antibiotic resistance in soil invertebrates. While bulk soil remains unaffected, the collembolan gut microbiome exhibits significant resistance gene enrichment under complex chemical exposure and diurnal warming.

Bioenergy Cropping Reduces the Spatiotemporal Scaling of Soil Bacterial Biodiversity

Advanced Science, EarlyView.
Consistent with patterns observed in plant and animal communities, soil bacterial communities exhibit significant species–time–area and phylogenetic–time–area relationships independent of nested structure. Bioenergy cropping significantly reduces the spatiotemporal scaling rates, particularly in sandy loam soils.

Single‐Atom Pt Anchoring on Self‐Doped ZrO2@G‐C3N4 Nanostructure Enables Efficient Photocatalytic Seawater Hydrogen Evolution

Advanced Science, EarlyView.
Grain‐like Zr3+‐ZrO2 and Pt single atoms are integrated into an S‐scheme Zr3+‐ZrO2@g‐C3N4 heterostructure to enable efficient visible‐light‐driven seawater hydrogen production. The combined effect of Pt single‐atom sites and the S‐scheme charge‐transfer pathway accelerates carrier separation, preserves strong redox ability, and markedly enhances ...

Studying conversion as a human activity system [PDF]

, 2002
This report was presented at the UK Organic Research 2002 Conference. Farmers convert to organic farming for a variety of reasons including environmental concerns, problems with conventional systems, and personal and financial reasons.

Global Nitrogen Deposition Promotes Carbon Sink Formation in Terrestrial Ecosystems

Advanced Science, EarlyView.
Nitrogen deposition alleviates ecosystem N limitation and enhances carbon sinks. Using 829 observations, we show 36% of deposited N is retained globally (39.15 Tg N yr−1), with distinct NHx and NOy contributions. This retention drives a terrestrial C sink of 0.88 Pg C yr−1 (25.48%), highlighting the importance of pool‐specific C:N stoichiometry ...
