Traditional spiral waves in period-2 domains typically exhibit defect lines, which can significantly influence spiral wave dynamics and have attracted considerable attention in recent years. The regulation of line defects in spiral waves holds significant implications in various domains, including cardiology and neuroscience.

Microbes Under Climate Refugia: Equable Subcommunity Rank Dynamics in Large-River Deltaic Estuaries.

Microorganisms, similar to macroorganisms, can be sheltered by climate refugia-a property overlooked due to their speciose nature. Using the latent Dirichlet allocation model to categorize microbial communities into ecologically distinct subcommunities, we conducted a 2-year survey of large-river deltaic estuaries (LDEs), recognized as refugial hotspots, and established rank hierarchies with the continuous time dynamic model to monitor temporal changes. We found that, consistent with macroecology, LDEs harbor distinct microbial community structures, with the abundance distribution of subcommunities exhibiting resilience against environmental perturbations, persisting on an annual cycle.

Glycosylated quercetin/cisplatin combinational nanodrugs for enhanced oxidative therapy and chemotherapy.

Drug self-assembly technology holds great potential for drug delivery; however, its practical application is often hindered by poor dispersibility, instability, and suboptimal therapeutic efficacy in monotherapy. To address these limitations, we developed a co-assembly strategy based on glycosylation and coordination crosslinking. Lactobionic acid (LA)-modified quercetin (QC) derivatives were synthesized via phenylboronic acid ester bonds and further assembled with cisplatin (CDDP) through Pt-O coordination bonds, forming LA-QC@Pt/NPs.

Core microbiota with antimonite oxidation coupled nitrogen fixation traits persist in the rhizosphere of pioneer plants in antimony tailings.

Antimony (Sb) tailings pose a dual challenge to plant colonization, combining high metal(loid) toxicity with nitrogen (N) limitation, both of which constrain pioneer plant establishment and hinder ecological restoration. Rhizosphere microbiota, particularly Sb(III) oxidation coupled with nitrogen fixation (SbNF) taxa, are critical in mitigating such stresses. However, the composition and persistence of these functional microbes may vary across plant species, leading to untargeted selection.
