Abstract Climate assessments have largely overlooked the radiative effect of anthropogenic coarse particulate matter (PMcoarse, with an aerodynamic diameter between 2.5 and 10 µm) in China. Despite its similar mass concentration to fine particulate matter (PM2.5), anthropogenic sources of PMcoarse in China have been much less studied and typically underrepresented in models. Here, we present a…

Researchers built an artificial intelligence tool that came up with 4000 novel research ideas in a matter of hours. Credit: Malte Mueller/Getty An ideas generator powered by artificial intelligence (AI) came up with more original research ideas than did 50 scientists working independently, according to a preprint posted on arXiv this month1. The human and…

As the global community grapples with the urgent need to mitigate climate change, nature-based solutions have emerged as a promising strategy for reducing greenhouse gas emissions and enhancing climate resilience. Recent studies suggest that natural climate solutions are modelled to potentially provide 37% of cost-effective CO2 mitigation needed through 2030 for a 66% chance of holding…

Abstract The gut microbiota exerts profound influence on poultry immunity and metabolism through mechanisms that yet need to be elucidated. Here we used conventional and germ-free chickens to explore the influence of the gut microbiota on transcriptomic and metabolic signatures along the gut-lung axis in poultry. Our results demonstrated a differential regulation of certain metabolites…

Abstract This study aims to investigate the effectiveness of iron oxide (Fe2O3) and carbon black in micro and nanoscales incorporated into an epoxy adhesive matrix for gamma-ray attenuation. The composites were prepared via a simple and cost-effective synthesis method. The grain size of powder NPs was measured using a transmission electron microscope (TEM), and the…

Abstract Neutrophil extracellular traps (NETs), crucial in immune defense mechanisms, are renowned for their propensity to expel decondensed chromatin embedded with inflammatory proteins. Our comprehension of NETs in pathogen clearance, immune regulation and disease pathogenesis, has grown significantly in recent years. NETs are not only pivotal in the context of infections but also exhibit significant…

A tunable SU(2) gauge field has been realized experimentally in a Raman momentum lattice using ultracold atoms. The chiral dynamics of the system have been investigated under different gauge potentials, whose non-Abelian nature was confirmed through observation of the non-Abelian Aharonov–Bohm effect.

Abstract Higher-order topological insulators (HOTIs) are unique materials hosting topologically protected states, whose dimensionality is at least by 2 lower than that of the bulk. Topological states in such insulators may be strongly confined in their corners which leads to considerable enhancement of nonlinear processes involving such states. However, all nonlinear HOTIs demonstrated so far…
