The UK economy grew at its fastest rate for more than two years in the three months to September. Between July and September, the economy expanded by 0.7%, accelerating from the previous three months, official figures, external show. The robust growth suggests a far more resilient economy than expected over the summer, despite the impact of higher energy prices from the Iran war. Strong growth in the services sector - the largest part of the economy, which includes non-physical goods such as consultancy services and computer programming as well as hotels and restaurants - helped boost the numbers. Within services, computer programming registered its fastest growth for the past three years, helped by cloud computing and AI-linked spending.

New UK agency will tackle'information warfare' from likes of Russia, Burnham says PM aims to'stem poisonous tide' of disinformation and deepfakes with National Centre for Information Defence Security chiefs will set up a new national centre to tackle disinformation and deepfakes from hostile states such as Russia, Andy Burnham has announced, saying the government had a duty to "stem the poisonous tide" from damaging British interests. The National Centre for Information Defence will "detect, attribute and disrupt" information attacks by foreign powers, many of which are enabled by AI, bringing together the intelligence agencies, law enforcement and social media companies. It will be tasked with making sure the UK has the defensive capability necessary to combat information warfare and build national resilience by helping communities to identify and combat disinformation, preventing a "distorted and untrue" narrative about the UK. Burnham said the country would have to go into the next decade "eyes wide open" about "insidious" campaigns, many of which had been orchestrated by Russia, which "twisted" what people at home felt about their own country and community. In eye-catching remarks, the prime minister suggested that Britons who were struggling with the cost of living and young people not in education, training or employment may be particularly susceptible to foreign influence online, underlining how inequality further undermined society.

Monitoring apps promise to keep young people safer online, but looking in on kids' phones can backfire. Online safety experts say there's a better way. Pam Wisniewski's digital adolescence showed her the best and the worst of the internet. At 14, she left an abusive home, where she'd been isolated in a fifth-wheel trailer at the end of a seven-mile dirt road. She moved in with her older sister and taught herself to type on AOL Instant Messenger. Online, she sought out the support and the community she'd lacked at home. She also discovered how thin the ice can be. "I sent my address to some guy in New Mexico to send me a mug with my name on it," she recalls. "And then I found a news story like five, 10 years later that he killed somebody." Those experiences set the course of her career.

In real-world information-seeking scenarios, users have dynamic and diverse needs, requiring RAG systems to demonstrate adaptable resilience. To comprehensively evaluate the resilience of current RAG methods, we introduce HawkBench, a human-labeled, multi-domain benchmark designed to rigorously assess RAG performance across categorized task types. By stratifying tasks based on informationseeking behaviors, HawkBench provides a systematic evaluation of how well RAG systems adapt to diverse user needs. Unlike existing benchmarks, which focus primarily on specific task types (mostly factoid queries) and rely on varying knowledge bases, HawkBench offers: (1) systematic task stratification to cover a broad range of query types, including both factoid and rationale queries, (2) integration of multi-domain corpora across all task types to mitigate corpus bias, and (3) rigorous annotation for high-quality evaluation. HawkBench includes 1,600 high-quality test samples, evenly distributed across domains and task types. Using this benchmark, we evaluate representative RAG methods, analyzing their performance in terms of answer quality and response latency. Our findings highlight the need for dynamic task strategies that integrate decision-making, query interpretation, and global knowledge understanding to improve RAG generalizability. We believe HawkBench serves as a pivotal benchmark for advancing the resilience of RAG methods and their ability to achieve general-purpose information seeking.

In cooperative Multi-Agent Reinforcement Learning (MARL), it is a common practice to tune hyperparameters in ideal simulated environments to maximize cooperative performance. However, policies tuned for cooperation often fail to maintain robustness and resilience under real-world uncertainties. Building trustworthy MARL systems requires a deep understanding of robustness, which ensures stability under uncertainties, and resilience, the ability to recover from disruptions--a concept extensively studied in control systems but largely overlooked in MARL. In this paper, we present a large-scale empirical study comprising over 82,620 experiments to evaluate cooperation, robustness, and resilience in MARL across 4 real-world environments, 13 uncertainty types, and 15 hyperparameters. Our key findings are: (1) Under mild uncertainty, optimizing cooperation improves robustness and resilience, but this link weakens as perturbations intensify. Robustness and resilience also varies by algorithm and uncertainty type.

Text-to-image (T2I) diffusion models have achieved impressive image generation quality and are increasingly fine-tuned for personalized applications. However, these models often inherit unsafe behaviors from toxic pretraining data, raising growing safety concerns. While recent safety-driven unlearning methods have made promising progress in suppressing model toxicity, they are found to be fragile to downstream fine-tuning, as we reveal that state-of-the-art methods largely fail to retain their effectiveness even when fine-tuned on entirely benign datasets. To mitigate this problem, in this paper, we propose ResAlign, a safety-driven unlearning framework with enhanced resilience against downstream fine-tuning. By modeling downstream fine-tuning as an implicit optimization problem with a Moreau envelope-based reformulation, ResAlign enables efficient gradient estimation to minimize the recovery of harmful behaviors. Additionally, a meta-learning strategy is proposed to simulate a diverse distribution of fine-tuning scenarios to improve generalization. Extensive experiments across a wide range of datasets, fine-tuning methods, and configurations demonstrate that ResAlign consistently outperforms prior unlearning approaches in retaining safety, while effectively preserving benign generation capability. Our code and pretrained models are publicly available here. .

As deep neural networks are deployed in safety-critical domains such as autonomous driving and medical diagnosis, stakeholders need explanations that are interpretable but also trustworthy with formal guarantees. Existing XAI methods fall short: heuristic attribution techniques (e.g., LIME, Integrated Gradients) highlight influential features but offer no mathematical guarantees about decision boundaries, while formal methods verify robustness yet remain untargeted, analyzing the nearest boundary regardless of whether it represents a critical risk. In safety-critical systems, not all misclassifications carry equal consequences; confusing a "Stop" sign for a "60 kph" sign is far more dangerous than confusing it with a "No Passing" sign. We introduce ViTaX (Verified and Targeted Explanations), a formal XAI framework that generates targeted semifactual explanations with mathematical guarantees. For a given input (class y) and a user-specified critical alternative (class t), ViTaX: (1) identifies the minimal feature subset most sensitive to the y->t transition, and (2) applies formal reachability analysis to guarantee that perturbing these features by epsilon cannot flip the classification to t. We formalize this through Targeted epsilon-Robustness, certifying whether a feature subset remains robust under perturbation toward a specific target class. ViTaX is the first method to provide formally guaranteed explanations of a model's resilience against user-identified alternatives. Evaluations on MNIST, GTSRB, EMNIST, and TaxiNet demonstrate over 30% fidelity improvement with minimal explanation cardinality.
