A brave eight-year-old boy helped save his grandad after the pair drifted more than two miles (3km) from the coast on a capsized kayak. Marley and his granscha, David Dai Jones, from Mountain Ash, Rhondda Cynon Taf, had been kayaking off Fontygary in the Vale of Glamorgan on 27 May when they capsized and were unable to get back onboard. Dai managed to help Marley back onto the kayak but could not climb back on himself. He remained in the water holding on as the pair drifted in the strong Bristol Channel currents. Despite the frightening situation, Marley remained calm and used a mobile phone kept in a waterproof pouch to contact his nan on shore, who called 999.

Did a Chatbot Write a Prize-Winning Story? If the possibility that one or more of the winners of the Commonwealth Short Story Prize was A.I.-generated chills us, it may be because of what it reveals about human writing. In early May, the Commonwealth Foundation announced the five regional winners for its influential Short Story Prize, which recognizes unpublished short fiction. One of the awardees, a Trinidadian writer named Jamir Nazir, was accused of A.I.-assisted cheating by a broad array of social-media users who seized upon his story's synthetic tics, glitchy metaphors, and general unreadability. "Maybe it was a name; maybe rain took a shape and decided to keep it.")

Machine learning-based decision support systems are increasingly deployed in clinical settings, where probabilistic scoring functions are used to inform and prioritize patient management decisions. However, widely used scoring rules, such as accuracy and AUC-ROC, fail to adequately reflect key clinical priorities, including calibration, robustness to distributional shifts, and sensitivity to asymmetric error costs. In this work, we propose a principled yet practical evaluation framework for selecting calibrated thresholded classifiers that explicitly accounts for uncertainty in class prevalences and domain-specific cost asymmetries. Building on the theory of proper scoring rules, particularly the Schervish representation, we derive an adjusted variant of cross-entropy (log score) that averages cost-weighted performance over clinically relevant ranges of class balance. The resulting evaluation is simple to apply, sensitive to clinical deployment conditions, and designed to prioritize models that are both calibrated and robust to real-world variations.

Pathology foundation models (PFMs) have emerged as powerful tools for analyzing whole slide images (WSIs). However, adapting these pretrained PFMs for specific clinical tasks presents considerable challenges, primarily due to the availability of only weak (WSI-level) labels for gigapixel images, necessitating multiple instance learning (MIL) paradigm for effective WSI analysis. This paper proposes a novel approach for single-GPU \textbf{T}ask \textbf{A}daptation of \textbf{PFM}s (TAPFM) that uses vision transformer (\vit) attention for MIL aggregation while optimizing both for feature representations and attention weights. The proposed approach maintains separate computational graphs for MIL aggregator and the PFM to create stable training dynamics that align with downstream task objectives during end-to-end adaptation. Evaluated on mutation prediction tasks for bladder cancer and lung adenocarcinoma across institutional and The Cancer Genome Atlas (TCGA) cohorts, TAPFM consistently outperforms conventional approaches, with H-Optimus-0 (TAPFM) outperforming the benchmarks. TAPFM effectively handles multi-label classification of actionable mutations as well. Thus, TAPFM makes adaptation of powerful pre-trained PFMs practical on standard hardware for various clinical applications.

A medical student asks questions to surgical support software tool that uses artificial intelligence. Moves are underway in Japan to develop artificial intelligence tools designed to help reduce burdens on surgeons. While the number of cancer patients in the country is projected to peak in around 2040 amid an aging population, too few people want to become surgeons due to the job's challenging work environment. The government is responding to the crisis by supporting companies working to develop AI technology to help surgeons.

Foundation models trained on large-scale de-identified electronic health records (EHRs) hold promise for clinical applications. However, their capacity to memorize patient information raises important privacy concerns. In this work, we introduce a suite of black-box evaluation tests to assess privacy-related memorization risks in foundation models trained on structured EHR data. Our framework includes methods for probing memorization at both the embedding and generative levels, and aims to distinguish between model generalization and harmful memorization in clinically relevant settings. We contextualize memorization in terms of its potential to compromise patient privacy, particularly for vulnerable subgroups. We validate our approach on a publicly available EHR foundation model and release an open-source toolkit to facilitate reproducible and collaborative privacy assessments in healthcare AI.
