Commodities Oil prices inch higher as focus shifts to supply, demand and Hormuz shipments
Oil prices edged higher on Tuesday, with WTI crude at $68.83 per barrel and Brent at $72.26, as the market shifted focus to supply-demand dynamics and recovering shipments through the Strait of Hormuz. A tanker was struck by a projectile near Oman, renewing geopolitical concerns, but gains were capped by OPEC+ output increases and record UAE production.
Comprehensive Survey of 120 Sign-Language Datasets Identifies Key Gaps in Scale and Annotation Standards
A comprehensive survey of 120 sign-language datasets across 35 languages reveals fragmented annotations, modality imbalance, and signer bias. The study introduces a 24-field datasheet and a public GitHub repository to standardize documentation and improve scalability.
New Benchmark Reveals Critical Vulnerabilities in LLM Agents Used for Safety-Critical Systems
A new benchmark called NRT-Bench tests multi-turn red-teaming of LLM agents operating a simulated nuclear power plant. Adaptive attacks cause safety limit breaches in up to 12.1% of sessions, with vulnerabilities nearly disjoint across models.
Medical Image Segmentation Survey: U-Net, Transformers, SAM and Clinical Translation Challenges
A new arXiv survey systematically reviews medical image segmentation methods based on U-Net, Transformer, and SAM architectures. It covers public datasets, evaluation metrics, and key challenges, aiming to guide future research and clinical adoption. The authors have made all related resources publicly available on GitHub.
Research Finds Anomalies in Multivariate Time Series Benchmarks Are Mostly Univariate
A study by researchers Pinet, Cumin, Berlemont, and Vaufreydaz on eight public benchmarks for multivariate time series anomaly detection (MTSAD) finds that labeled anomalies are overwhelmingly univariate—no cross-channel rupture occurs without a univariate deviation. The paper's diagnostic framework and synthetic data experiments show that current benchmarks do not justify cross-channel modeling, as channel-dependent detectors offer no measurable gain over channel-independent ones. The authors call for more structurally diverse evaluation sets.
LLM Tutor Benchmarks Ignore Students Who Bypass Scaffolding, Study Finds
A study introduces two metrics—Chatbot Scaffolding and Student Uptake—and applies them to 9,490 chats across benchmarks and real-world deployments. It finds that real-world students often bypass pedagogical scaffolding, revealing a mismatch between lab evaluations and actual usage.
