Researchers Propose KG-ER, a New Conceptual Schema Language for Knowledge Graphs
Computer scientists have proposed KG-ER, a conceptual schema language designed to describe the structure of knowledge graphs in a representation-independent way. The language aims to capture semantic information while working across different storage formats including relational databases, property graphs, and RDF. The development addresses a gap in standardizing how knowledge graph structures are conceptually defined regardless of their underlying implementation.
Researchers have introduced KG-ER, a conceptual schema language specifically designed for knowledge graphs that can describe their structure independently of the underlying representation format—whether stored in relational databases, property graphs, or RDF systems. The language is intended to help capture and preserve the semantics of information stored in knowledge graphs while providing a unified framework for conceptual modeling. The work has been published in the Proceedings of IRIS-AI and represents an effort to standardize how knowledge graph structures are defined at the conceptual level. This approach could facilitate better interoperability and understanding of knowledge graphs across different technical implementations and use cases.

Topology-Aware Thermodynamics Improves DNA Probe Specificity Design
Researchers developed a new framework for designing DNA probes that accounts for the spatial organization of matched sequences, not just overall thermodynamic stability. Traditional methods rely on scalar measures like melting temperature and free energy, which miss how mismatches are distributed along the probe. The approach could improve diagnostic accuracy in applications like HPV detection and gene expression profiling.
Study Identifies Optimal Thermal Dose for Combining Focused Ultrasound with Immunotherapy in Tumors
Researchers used multimodal PET imaging to identify an optimal thermal dose range for focused ultrasound ablation that destroys tumor tissue while preserving conditions for immunotherapy delivery. The study found that excessive heating collapses blood vessels needed for antibody access, while insufficient heating fails to adequately reduce tumor burden. The findings could guide clinical design of combination treatments pairing thermal ablation with immunotherapies.
Plant MSH1 Protein Functions as Mismatch-Directed Nuclease for Organelle Genome Maintenance
Researchers have identified the precise mechanism by which the AtMSH1 protein in Arabidopsis plants recognizes and cleaves DNA mismatches and lesions, preventing mutations in organellar genomes. The protein combines a DNA mismatch recognition module with a nuclease domain that makes staggered cuts at specific positions relative to DNA damage. This discovery explains how plants maintain unusually low mutation rates in their mitochondrial and chloroplast DNA compared to other eukaryotes.
