Elastica++: New computational framework for simulating large assemblies of flexible rod-like structures
Researchers have released Elastica++, an open-source software framework designed to simulate the dynamics of large numbers of interacting slender, flexible structures using Cosserat-rod mechanics. The tool combines high-performance computing with the ability to model complex physical interactions across diverse applications from soft robotics to biological systems. This addresses a significant gap in computational tools needed for studying emergent behavior in systems of elastic structures at scale.
Elastica++ is a new computational framework that enables high-fidelity simulations of soft, slender structures—such as those found in biomimetic materials and soft robotics—at large scales. The software implements the Cosserat-rod model, a mathematical approach for modeling the mechanics of thin, flexible bodies, and uses performance-oriented computing techniques to achieve teraflop-scale throughput even with complex interactions. The framework is flexible enough to work with external numerical solvers, supporting multiphysics simulations. The developers demonstrated its capabilities across diverse applications including passive metamaterials, active-matter systems, cilia carpets, soft magnetic microrobots, and schooling swimmers, establishing it as a versatile tool for studying how emergent behaviors arise in large interacting assemblies of elastic structures.

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.
