Vascularized composite allotransplantation, or VCA, has expanded reconstructive options for people with devastating tissue loss. Hand, face, abdominal wall, uterine, penile, scalp and laryngeal transplants can restore functions and appearances that conventional reconstruction may not fully reproduce. But these procedures carry a distinctive biological cost: recipients generally need lifelong immunosuppressive treatment to prevent their immune […]

A long-term study of liver transplant recipients has found that the most pronounced changes in DNA methylation occurred between five and ten years after transplantation, and that these changes were concentrated in immune-related biological pathways. The findings suggest that extended survival after a liver transplant may be accompanied by sustained remodeling of the immune system’s […]

Neurosurgeons in London have successfully carried out a live artificial intelligence assisted operation to remove a brain tumour, described as a world first for such surgery.Rhys Hibbert, a 48 year old patient, could have lost his sight without the surgery at the National Hospital for Neurology and Neurosurgery (NHNN) in London earlier this year.During the operation the AI system analysed the live surgical video feed in real time, rather than using presurgery scans. The surgeons remained in full control, but the technology helped the team make more precise decisions by highlighting critical structures at the base of the brain.The procedure represented the first time the technology has been used on a patient this way.Because blood vessels and nerves controlling vision are so tightly packed together in the pituitary gland, and going a millimetre wrong can make a critical difference leading to death, blindness, or stroke, the surgical team used AI...

arXiv:2608.27360v1 Announce Type: new Abstract: Speaker anonymization suppresses speaker-identifying attributes from speech while preserving linguistic content and quality. We propose repurposing XTTSv2, a multilingual voice cloning model trained on 27k hours of speech, for speaker anonymization without retraining. Our key insight is that XTTSv2's voice cloning capabilities preserve prosodic structure independently of speaker identity, enabling voice conversion by conditioning on a pseudo-speaker. We introduce an iterative refinement strategy that balances privacy and utility by maximizing a harmonic mean of speaker dissimilarity and intelligibility. Evaluated on seven European languages across CommonVoice and Multilingual LibriSpeech, our system achieves near-optimal privacy (EER $\approx$ 0.49), competitive intelligibility, and substantially better speech quality than dedicated anonymization baselines, while requiring no language-specific training. We release the code here:

arXiv:2608.26162v1 Announce Type: new Abstract: Safety-critical mental-health support systems must distinguish when supportive conversation is appropriate from when free-form generation should be blocked. This paper presents Anian, a safety-gated multimodal AI backend for perinatal mental-health support and mindfulness-intervention routing. Anian is not intended to diagnose psychiatric conditions or replace clinical care or crisis intervention. Its modular pipeline places generative AI downstream of structured state representation, conservative risk fusion, and response gating. User text or voice-derived ASR transcripts are mapped into four linked layers: L1 emotion states, L2 psychosocial constructs, L3 safety risk, and L4 intervention routes. Local text- and rule-based safety evidence is fused with external voice-derived evidence using a highest-risk-priority rule, S_fusion = max(S_local, S_external). At moderate or high fused risk, ordinary AI-generated responses and text-to-speech

Researchers here show that a few different senolytic approaches improve the state of the population of microglia in the white matter of the brain in aged mice. This is much as one might expect, given past work into the effects of clearing senescent cells on cognitive function and neurodegeneration in various mouse models. Microglia are innate immune cells of the brain. The presence of senescent and inflammatory microglia is important in the age-related disruption of normal function in the brain, and removing them is beneficial. Sadly, little progress has been made to date in assessing established low-cost senolytic drugs in patients with neurodegenerative conditions; one small clinical trial was conducted for Alzheimer's disease, and that is about it. Brain white matter undergoes structural and functional […]

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) said Friday they have developed a biomolecular artificial intelligence (AI) model, called K-Fold, that predicts protein structures and how drug candidates bind to them, with the aim of speeding up new drug development using homegrown technology. The model was built by a KAIST-led group called Team KAIST as part of a project run by Korea's Ministry of Science and ICT to develop AI foundation models specialized by field. KAIST President Bae Chung-sik said the project reflects the importance of "sovereign AI" — a country's ability to develop and control its own core technology — for national competitiveness in the AI era. K-Fold is designed to predict not only the 3D shape of a single protein, but also how it interacts with other proteins, drug candidates, or genetic material such as DNA and RNA, and where and how a candidate compound binds. That combination of structure prediction and binding prediction is

arXiv:2608.24934v1 Announce Type: new Abstract: Accurate field plant disease diagnosis requires reliable fusion of uncertain and conflicting perceptual evidence. We present the Hybrid Hierarchical Multi-Agent Framework (H$^{2}$MAF), combining decision-level fusion of EfficientNet-B3 and ConvNeXt-Tiny with semantic arbitration by open-weight multimodal large language models (MLLMs), Gemma 4 E4B and Qwen3.5 4B, using structured JSON evidence to generate explainable diagnoses, risk levels, treatment urgency, and financial exposure. (H$^{2}$MAF) is evaluated on 14,364 images (1,370 test images) across PlantDoc (2,922 images, 27 classes) and two non-public, continuously captured Cornell robot-acquired field datasets: Stage 2 (20 GB; 4,215 images) and Stage 4 (40 GB; 7,227 images), covering Early Blight, Late Blight, and Septoria Leaf Spot under uncontrolled field conditions. On PlantDoc, Gemma improves accuracy from 63.9% to 68.5%, achieving +7.6 points on the 41.7% CNN-conflict subset.

arXiv:2608.24890v1 Announce Type: new Abstract: Mental health challenges in Africa remain under-addressed due to inadequate infrastructure, stigma, and a chronic shortage of professionals. Artificial Intelligence (AI)-powered chatbots are emerging globally as low-cost, accessible tools that can offer psychological support. This paper presents a systematic review of 52 empirical studies published between 2017 and 2025, critically analysing their cultural, linguistic, and infrastructural relevance to African contexts. The findings demonstrate the potential of AI chatbots to improve accessibility, reduce symptoms of anxiety and depression, and expand psychosocial support, yet reveal limited African-specific adaptation. Most systems remain rooted in Western models and English-language designs, leaving critical gaps in local relevance, inclusivity, and sustainability. Based on the findings, the authors develop a Culturally Adaptive Digital Mental Health (CADMH) framework that integrates

On the forearms of those working in the laboratory at the University of Oslo, one thing stands out: mysterious round or cross-shaped scars on the skin. Here, researchers need skin cells, and they themselves step up in the service of research. The skin cells are allowed to grow and multiply, and then the work begins to reprogram them into so-called iPS cells, induced pluripotent stem cells. These are cells that can divide indefinitely and give rise to all types of specialized cells in the body. They can, for example, become muscle, blood or nerve cells.

Director Baek Jong-yeol teamed up with actor Koo Kyo-hwan to adapt the popular webtoon "Reawakened Man" into the action film "Reawaken Man: The Red." The director said he focused on reshaping the original comic's premise into a fast-paced action film about an unemployed youth who gains the ability to revive after death. "The original webtoon has a very famous premise about an ordinary person acquiring a completely extraordinary power," Baek, a former commercial and music video director who previously directed "The Beauty Inside" (2015) and Netflix's "Believer 2" (2023), said Wednesday. "My main focus was figuring out how to effectively reconstruct this narrative within the short runtime of a film medium." "Reawaken Man: The Red" follows Seok-hwan (Koo), an unemployed young man. After dying, he realizes he possesses a supernatural ability to revive 72 hours after death, which makes him the target of a mysterious group. Koo continues his impressive box-office streak following his lead

arXiv:2608.24885v1 Announce Type: new Abstract: Action-conditioned world models are increasingly used as learned simulators for policy evaluation and improvement, yet their effectiveness rests on an unverified assumption: generated futures faithfully reflect arbitrary valid actions. Existing benchmarks are typically confined to expert demonstrations, leaving off-expert action following inadequately evaluated. To address this gap, we introduce WorldEcho, which probes action following over a broader action distribution using visual integrity and SE(3) trajectory alignment. Our diagnosis shows that current world models reasonably execute expert actions but struggle with diverse off-expert trajectories, either ignoring the commanded actions or producing visually invalid rollouts. We further propose WorldSync, which strengthens action following along three complementary axes: distributional coverage, representational grounding, and intervention-effect alignment. It broadens the training

arXiv:2608.24461v1 Announce Type: new Abstract: System prompts can be extracted from commercial LLMs with over 80\% success and redeployed at zero cost, yet a prompt owner has no way to verify whether a suspected deployment is a clone. We propose Black-Box Behavioral Fingerprinting (BBF): the prompt owner registers a behavioral signature from model outputs and later tests whether a suspect deployment matches that signature more closely than an unrelated baseline. BBF requires only black-box API access. Through a large-scale study (4 model families, 8 benchmarks, 288{,}000 responses), we find that prompt choice explains 24.4\% of output variance and same-model detection reaches AUC 0.876. Cross-model performance is bounded by detector identity, with off-diagonal AUC ranging from 0.845 (Claude as detector) down to 0.665 (Qwen) and overall mean 0.725. BBF resists non-adaptive prompt paraphrasing (AUC $\geq 0.889$) and is robust to imperfect extraction, but a single-sentence formal-tone

arXiv:2608.24338v1 Announce Type: new Abstract: Inference-time decoding methods improve LLM reasoning by exploring multiple candidate trajectories, yet treat each trajectory as atomic: either retaining it whole or discarding it irreversibly. This wastes computation on partially promising candidates whose high-quality prefixes are abandoned alongside degraded suffixes. We introduce Selective Regenerative Decoding (SRD), which routes each candidate to discard, keep, or refine only the degraded portion of the suffix while preserving the useful prefix of borderline candidates, without requiring a larger target model. Under mild assumptions, SRD achieves a provable 1.28-to-1.36-fold gain in sample efficiency over rejection sampling with strictly higher expected trajectory quality, with the gain growing as the candidate pool grows. Across MATH500, GPQA Diamond, HotpotQA, and AlpacaEval with multiple generation-reward model pairs, SRD matches Best-of-N accuracy with substantially fewer

Patients with sickle cell disease are often hesitant to undergo transformative gene therapy—the current lengthy process requires multiple hospital visits to collect enough stem cells. Researchers from Boston Children's Hospital have helped smooth the road to gene therapy with a new approach that collects enough of the patient's stem cells in a single hospital admission for most patients, improving the turnaround time for genetically altering and infusing the cells back into the patient. The long-term follow-up results of the first-in-human phase I pilot clinical trial were recently published in Blood.
