Detecting supramolecular organic nanoparticles during heat wave - Science | AAAS

A joint research team fabricated a two-dimensional structure that exhibits properties of both the honeycomb and Kagome lattices using organic molecules. They discovered that edge states specific to topological materials (states that exist only at the edges and are distinct from those in the interior) appear in this structure. The team included researchers from NIMS, Toyota Kosen (National Institute of Technology, Toyota College), Saga University, Nara Women's University, Kiel University (Germany) and other institutions.

Researchers at HZB have taken an important step toward bringing one of quantum physics' more unusual predictions closer to experimental reality. Fractons, exotic quasiparticles previously predicted in quantum spin liquids using highly generalized gauge field theories, have now also appeared in simulations of a more realistic quantum solid-state model. Quasiparticles emerge from the collective behavior of many interacting particles inside a solid. For instance, vibrations moving through a crystal lattice can be described as quasiparticles known as phonons.

AbstractNanoplastics are emerging environmental contaminants that threaten sustainable crop production and food safety by disrupting mineral nutrient homeostasis, impairing physiological processes, and inducing reactive oxygen species (ROS)-mediated oxidative stress. Nanoparticle-based interventions have emerged as a promising strategy for mitigating nanoplastic-induced phytotoxicity and enhancing plant stress resilience. In the present study, the protective effects of potassium nanoparticles (K-NPs; 10 mmol L⁻1) against nanoplastic-induced stress (4 mg kg⁻1 soil) were investigated in Solanum lycopersicum using a randomized complete block design with five biological replicates per treatment. Nanoplastics were applied to the soil, whereas K-NPs were administered as a foliar spray at 30 days after sowing (DAS).

IntroductionTerrestrial snails (Gastropoda) play diverse ecological roles; however, many species are considered serious agricultural pests worldwide. They feed on various plant parts, including leaves, stems, roots, and fruits, leading to significant yield losses and reduced crop quality. In addition, their mucus and fecal contamination lower the market value of produce. Some species also act as intermediate hosts for parasites affecting humans and animals. Due to their increasing spread and adaptability, terrestrial snails are recognized as a major threat to sustainable agriculture1. The white garden snail, Theba pisana, is one of the most destructive land snail species in Mediterranean and Middle Eastern regions and has become an invasive pest in many parts of the world. It is characterized by high reproductive capacity, strong environmental tolerance, and aggregation behavior, which enhances its survival and facilitate rapid population expansion. This species feeds on a wide range of crops, including cereals, vegetables, and fruit trees, causing substantial economic losses and negatively affecting different plant growth stages2.

AbstractEpithelial-to-mesenchymal transition (EMT) is a key driver of colorectal cancer (CRC) progression and metastasis. Identifying pivotal EMT-related genes and novel therapeutic approaches may enhance patient outcomes. In this study, we analyzed EMT-related gene expression in CRC using TCGA data and identified differentially expressed genes via protein-protein interaction networks and centrality analysis. The anticancer effects of ZnO and ZnO@glu-Carvacrol nanoparticle were evaluated in HCT-116 and HT-29 cells using MTT assays, gene expression profiling of proliferation and apoptosis markers, colony formation, and scratch wound-healing assays. Among 200 EMT-related genes, 75 were upregulated and 69 downregulated in CRC. Seventeen hub genes were identified, with SERPINE1 and BGN showing the strongest association with poor patient survival in exploratory survival analyses.
