This study integrates Land Change Modeling with the Plan Integration for Resilience Scorecard methodology to assess coastal communities' preparedness for uncertain future urban growth and flood hazards. Findings indicate that, under static climate conditions, the network of plans in Tampa is well prepared across all urban growth scenarios, but less so in the face of a changing climate. Specifically, scenario outputs that consider climate change suggest the need for more resilient growth to reduce flood vulnerability compared with the current land use plan.

Oxytocin (OXT) plays a critical role in stress-induced affiliative behavior, with important implications for socio-economic decision-making. In this study, 95 healthy young males were randomly assigned to four groups, receiving either 32 IU of exogenous OXT or a placebo (PBO) before undergoing the Trier Social Stress Test (TSST) or a control procedure, followed by participation in the Ultimatum Game (UG) as responders, allocating ¥50. The results indicated that OXT inhibited the hypothalamic-pituitary-adrenal (HPA) axis stress response, enhanced sympathetic nervous system activity, and increased subjectively perceived stress.

Ammonium perchlorate (AP), which is the most commonly used oxidant in composite propellants, plays a vital role in the combustion performance of propellants. In this work, by coating the AP surface with a self-assembled coating layer of gallic acid (GA) and transition metal ions (Cu or Fe) and then connecting it with a 1,1,2,2-perfluorodecyltrichlorosilane (PDTS) coating layer, the AP@GA-M@PDTS (M = Cu or Fe) composite was successfully prepared. Molecular dynamics simulation calculations show that GA and AP have a good binding ability.

DNA walkers, as structurally and functionally programmable signal amplification tools, exhibit great potential for application in the field of biosensing. Traditional DNA walkers often rely on enzymes for operation, posing compatibility challenges, while the handful of existing enzyme-free DNA walkers demonstrate limited performance. To address this, we innovatively developed an efficient enzyme-free 3D DNA walker with dual capture and dual output capabilities.

Integration of natural and cultural resource management is urgently needed to combat the effects of climate change. Scientists must contend with how human-induced climate change and rapid population expansion are fundamentally reworking densely inhabited coastal zones. We propose that a merger of archaeology, environmental science, and land management policy-different yet intertwined domains-is needed to address dramatic losses to biocultural resources that comprise coupled cultural-natural systems.

Prenatal exposure to hazardous environmental pollutants is a critical global concern due to their confirmed presence in umbilical cord blood, indicating the ability of pollutants to cross the placental barrier and expose the fetus to harmful compounds. However, the transplacental transfer efficiencies (TTEs) of many pollutants remain underexplored. Herein, we developed a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method to quantitatively analyze 91 environmental pollutants, including 13 bisphenols (BPs), 18 organophosphorus flame retardants (OPFRs), 7 brominated and other flame retardants (BFRs), 34 phthalates (PAEs), and 19 per- and polyfluoroalkyl substances (PFASs), in paired maternal and cord serums.

Article Synopsis
  • This study examines how both soil properties and microbial communities affect nitrous oxide (N₂O) emissions in two different agricultural soils from China, revealing that black soil (BS) produces more N₂O than fluvo-aquic soil (FS).
  • Through cross-inoculation experiments, researchers demonstrated that the type of recipient soil significantly influences gas emissions regardless of the microbial inoculum, with BS showing a higher N₂O ratio than FS.
  • Metagenomic analysis indicated that the denitrifying bacterial communities adapt based on soil type, suggesting that optimizing soil conditions could help reduce N₂O emissions in agriculture.

Article Synopsis
  • Active polysaccharides were extracted from Brassica rapa L. (BRP), with structural characterization indicating it is an acidic heteropolysaccharide composed primarily of Ara, GalA, and GlcA.
  • The study found that BRP effectively improved immune functions in cyclophosphamide-induced immunosuppressed mice by boosting thymus and spleen indices, enhancing immune cell activity, and increasing antioxidant levels.
  • BRP also elevated serum cytokines and immunoglobulins, influenced key immune signaling pathways, and modified the composition of intestinal microbiota, suggesting its potential as a natural immunomodulator.

The traditional chemotherapeutic agents' disadvantages such as high toxicity, untargeting and poor water solubility lead to disappointing chemotherapy effects, which restricts its clinical application. In this work, novel size-appropriate and glutathione (GSH)-responsive nano-hydrogels were successfully prepared via the active ester method between chitosan (containing -NH) and cross-linker (containing NHS). Especially, the cross-linker was elaborately designed to possess a disulfide linkage (SS) as well as two terminal NHS groups, namely NHS-SS-NHS.
