Microalgal genomes contain a vast "dark proteome"-sequences lacking detectable homology that evade conventional classification tools. We developed LA4SR (language modeling with AI for algal amino acid sequence representation), a framework using transformer- and state-space models to classify translated ORFeomes across ten algal phyla. Training on ∼77 million sequences, LA4SR achieves near-complete recall, accelerates classification by ∼10,701× relative to BLASTP+, and generalizes robustly to unseen sequences using less than 2% of available data. Models trained on synthetic, chimeric (terminal information [TI]-free) sequences maintained high accuracy, demonstrating that internal sequence features alone can drive robust classification. Inference speed and scalability were further enhanced under TI-free settings, supporting rapid annotation of large proteomic datasets. Custom explainability tools revealed interpretable amino acid patterns linked to evolutionary and biophysical features. Designed for accessibility across disciplines, LA4SR integrates biological context and computational innovation in parallel, enabling both biologists and data scientists to interrogate the microbial dark proteome.

微藻基因组包含一个巨大的“暗蛋白质组”——缺乏可检测的同源性的序列,逃避了传统的分类工具。我们开发了LA4SR(藻类氨基酸序列表示的AI语言建模),这是一个使用转换和状态空间模型对10个藻类门的翻译ORFeomes进行分类的框架。在约7700万个序列上训练,LA4SR实现了近乎完全的召回,相对于BLASTP+加速了约10,701倍的分类,并且使用不到2%的可用数据稳健地推广到未见过的序列。在合成、嵌合(末端信息[TI]无)序列上训练的模型保持了较高的准确性,表明内部序列特征本身可以驱动鲁棒分类。在无ti设置下,推理速度和可扩展性进一步增强,支持大型蛋白质组学数据集的快速注释。定制的可解释性工具揭示了与进化和生物物理特征相关的可解释氨基酸模式。LA4SR旨在跨学科访问,将生物学背景和计算创新并行集成,使生物学家和数据科学家能够询问微生物暗蛋白质组。

Fully automated self-driving laboratories promise high-throughput, large-scale scientific discovery by reducing repetitive labor. However, they require deep integration of laboratory knowledge, which is often unstructured, multimodal, and hard to incorporate into current AI systems. This paper introduces the "k-agents" framework, designed to support experimentalists in organizing laboratory knowledge and automating experiments with agents. The framework uses large-language-model-based agents to encapsulate laboratory knowledge, including available operations and methods for analyzing results. To automate experiments, execution agents break multistep procedures into agent-based state machines, interact with other agents to execute steps, and analyze results. These results drive state transitions, enabling closed-loop feedback control. We demonstrate the system on a superconducting quantum processor, where agents autonomously planned and executed experiments for hours, successfully producing and characterizing entangled quantum states at human-level performance. Our knowledge-based agent system opens new possibilities for managing laboratory knowledge and accelerating scientific discovery.

全自动自动驾驶实验室通过减少重复劳动,有望实现高通量、大规模的科学发现。然而,它们需要深入整合实验室知识,而这些知识通常是非结构化的、多模式的,很难整合到当前的人工智能系统中。本文介绍了“k-agents”框架,旨在支持实验人员组织实验室知识并使用agent自动化实验。该框架使用基于大语言模型的代理来封装实验室知识,包括可用的操作和分析结果的方法。为了使实验自动化,执行代理将多步骤过程分解为基于代理的状态机,与其他代理交互以执行步骤,并分析结果。这些结果驱动状态转换,实现闭环反馈控制。我们在超导量子处理器上演示了该系统,其中代理自主计划和执行实验数小时,成功地产生和表征了人类水平性能的纠缠量子态。我们的基于知识的代理系统为管理实验室知识和加速科学发现开辟了新的可能性。

Hierarchical affinity landscape navigation through learning a shared pocket-ligand space. 层次化亲和景观导航,通过学习共享口袋配体空间。
IF 7.4 Q1 COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE Pub Date : 2025-09-17 eCollection Date: 2025-10-10 DOI: 10.1016/j.patter.2025.101371

The structure of the protein binding pocket governs the ligand binding affinity by providing crucial intermolecular interactions and spatial compatibility. While existing methods have leveraged these structural insights to advance affinity prediction, they often treat virtual screening and hit-to-lead optimization separately, mainly due to incompatible speed-accuracy requirements. However, these two tasks complement each other, and their integration enables broader chemical exploration while preserving focus on affinity-determining substructures. Here, we present ligand unified affinity (LigUnity), a foundation model for affinity prediction that jointly embeds ligands and pockets into a shared space. In particular, LigUnity learns coarse-grained active/inactive distinction through scaffold discrimination and fine-grained pocket-specific ligand preference through pharmacophore ranking. We demonstrate the effectiveness and versatility of LigUnity on eight benchmarks across six settings. In virtual screening, LigUnity outperforms 24 methods with >50% improvement and demonstrates robust generalization to novel targets. In hit-to-lead optimization, it achieves state-of-the-art performance across split-by-time, split-by-scaffold, and split-by-unit settings, emerging as a cost-efficient alternative to free energy perturbation. We further showcase how LigUnity can be employed in an active learning framework for tyrosine kinase 2 (TYK2) to efficiently find optimal ligands. Collectively, these results establish LigUnity as a versatile foundation model for affinity prediction, offering broad applicability across the drug discovery pipeline.

蛋白质结合袋的结构通过提供关键的分子间相互作用和空间相容性来控制配体的结合亲和力。虽然现有的方法利用这些结构洞察来推进亲和度预测,但它们通常将虚拟筛选和hit-to-lead优化分开处理,这主要是由于不兼容的速度精度要求。然而,这两项任务是相辅相成的,它们的整合使得更广泛的化学探索成为可能,同时保持对亲和力决定子结构的关注。在这里,我们提出了配体统一亲和力(LigUnity),这是一个将配体和口袋共同嵌入到共享空间中的亲和力预测的基础模型。特别是,LigUnity通过支架识别学习粗粒度的活性/非活性区分,通过药效团排序学习细粒度的口袋特异性配体偏好。我们在六个设置的八个基准上展示了liunity的有效性和多功能性。在虚拟筛选中,LigUnity优于24种方法,提高了50%,并且对新目标具有鲁棒泛化能力。在hit-to-lead优化方面,它可以在按时间、按支架和按单元设置的情况下实现最先进的性能,成为自由能扰动的经济高效替代方案。我们进一步展示了如何将LigUnity应用于酪氨酸激酶2 (TYK2)的主动学习框架中,以有效地找到最佳配体。总的来说,这些结果使LigUnity成为亲和力预测的通用基础模型,在整个药物发现管道中具有广泛的适用性。

Facing the possibility of consciousness in human brain organoids. 面对人脑类器官中意识的可能性。

Human brain organoids (HBOs) have emerged as transformative models for neurodevelopment and disease, yet ethical concerns persist regarding their potential to develop consciousness. Since 2020, a growing cohort of neuroscientists and philosophers has dismissed these concerns as unscientific, citing limited structural complexity, absence of bodily integration and environmental interaction, and a prevailing neuroscientific consensus against the feasibility of any, or any near-future, emergence of HBO consciousness, thus challenging any suggested revisions of ethical guidelines and safeguards. We argue that this dismissal is premature. Drawing on neuroscientific benchmarks, comparisons to the developing human brain, contemporary theories of consciousness, and principles of natural developmental progression, we question the basis for selectively excluding consciousness from among HBOs' expanding functional repertoire. We caution against enshrining such skepticism into dogma or using it to defer ethical engagement. Instead, we advocate for proactive, ongoing assessment of the moral implications of advancing HBO capabilities.

人类大脑类器官(HBOs)已经成为神经发育和疾病的变革性模型,但关于它们发展意识的潜力的伦理问题仍然存在。自2020年以来,越来越多的神经科学家和哲学家认为这些担忧是不科学的,理由是结构复杂性有限,缺乏身体整合和环境相互作用,以及普遍存在的神经科学共识反对HBO意识出现的可行性,或在不久的将来出现的可行性,因此挑战了任何修改伦理准则和保障措施的建议。我们认为这种驳回为时过早。根据神经科学的基准,与人脑发育的比较,当代意识理论和自然发展过程的原则,我们质疑有选择地将意识排除在HBOs扩展功能库之外的基础。我们警告不要将这种怀疑主义奉为教条,或者用它来推迟道德参与。相反,我们主张对推进HBO能力的道德影响进行积极、持续的评估。

A multimodal LLM-agent framework for personalized clinical decision-making in hepatocellular carcinoma. 肝细胞癌个体化临床决策的多模式LLM-agent框架
IF 7.4 Q1 COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE Pub Date : 2025-09-08 eCollection Date: 2025-12-12 DOI: 10.1016/j.patter.2025.101364

Hepatocellular carcinoma (HCC) treatment is challenging due to tumor heterogeneity and patient variability. Current guidelines often overlook individual factors, limiting treatment precision. We developed an integrated framework combining radiomics, deep learning, and large language model (LLM)-based decision agents to generate personalized HCC treatment recommendations. A modified GhostNet incorporating dilated convolutions, channel and spatial attention mechanism (CBAM), and residual channel attention (RCA) modules was trained on MRI to predict pathological markers such as microvascular invasion (MVI), capsule presence, and tumor differentiation. A fusion model integrating radiomics and deep learning enhanced prediction accuracy. Six AI agents processed structured multimodal data and generated individualized treatment strategies, which were evaluated by hepatobiliary surgeons. The fusion model significantly improved prediction accuracy, with MVI and capsule presence reaching 0.8902 and 0.8765, respectively. DeepSeek-R1 achieved the highest clinical relevance score, followed by GPT-4 and Med-PaLM 2. This framework demonstrates the feasibility of AI-assisted, patient-specific HCC decision-making, offering a promising direction for precision oncology.

由于肿瘤的异质性和患者的可变性,肝细胞癌(HCC)的治疗具有挑战性。目前的指导方针往往忽略了个体因素,限制了治疗的准确性。我们开发了一个结合放射组学、深度学习和基于大语言模型(LLM)的决策代理的集成框架,以生成个性化的HCC治疗建议。改进后的GhostNet结合了扩张卷积、通道和空间注意机制(CBAM)和剩余通道注意(RCA)模块,在MRI上进行训练,以预测微血管侵袭(MVI)、囊存在和肿瘤分化等病理标记。结合放射组学和深度学习的融合模型提高了预测精度。六个人工智能代理处理结构化的多模式数据并生成个性化的治疗策略,由肝胆外科医生进行评估。融合模型显著提高了预测精度,MVI和胶囊存在度分别达到0.8902和0.8765。临床相关性评分最高的是DeepSeek-R1,其次是GPT-4和Med-PaLM 2。该框架证明了人工智能辅助的HCC患者特异性决策的可行性,为精准肿瘤学提供了一个有希望的方向。

In vitro fertilization (IVF) has significantly advanced the treatment of infertility, yet success rates remain modest due to its complexity and reliance on clinical experience. Recent advances in artificial intelligence (AI) offer promising tools to support decision-making throughout the IVF process. This review summarizes current applications of AI in IVF by organizing studies according to the data modality they use, including structured health records, biomedical images, and omics data. For each modality, we describe representative tasks, model performance, and key methodological progress. We also examine the potential of emerging AI approaches, such as multi-modal learning and large language models. In addition, we acknowledge ongoing challenges, including limited model generalizability, data bias, and the need for clinically validated, transparent AI systems. While the integration of AI into IVF is promising, its success will depend on rigorous validation, ethical safeguards, and interdisciplinary efforts to ensure safe and equitable implementation.

体外受精(IVF)在治疗不孕症方面取得了显著进展,但由于其复杂性和对临床经验的依赖,成功率仍然不高。人工智能(AI)的最新进展为支持整个试管婴儿过程中的决策提供了有前途的工具。本文综述了人工智能在体外受精中的应用,根据他们使用的数据模式组织研究,包括结构化健康记录、生物医学图像和组学数据。对于每种模式,我们描述了代表性任务、模型性能和关键的方法进展。我们还研究了新兴人工智能方法的潜力,如多模式学习和大型语言模型。此外,我们承认持续存在的挑战,包括有限的模型泛化性、数据偏差以及对临床验证、透明的人工智能系统的需求。虽然人工智能与试管婴儿的结合很有希望,但其成功将取决于严格的验证、道德保障和跨学科的努力,以确保安全和公平的实施。

The rise of data-driven scientific investigations has made research data management (RDM) essential for good scientific practice. Implementing RDM is a complex challenge for research communities, infrastructures, and host organizations. Generic RDM guidelines often do not address practical questions, and disciplinary best practices can be overwhelming without proper context. Once guidelines are established, expanding their reach and keeping them up to date is challenging. The RDMkit is an open community-led resource designed as a gateway to reach the wealth of RDM knowledge, tools, training, and resources in life sciences. The RDMkit provides best-practice guidelines on common RDM tasks expected of data stewards and researchers, specific data management challenges and solutions from life science domains, and tool assemblies showcasing holistic solutions to support the research data life cycle. Built on a reusable open infrastructure, the RDMkit allows organizations to create their own guidelines using it as a blueprint.

数据驱动的科学调查的兴起使得研究数据管理(RDM)对于良好的科学实践至关重要。实现RDM对于研究团体、基础设施和宿主组织来说是一个复杂的挑战。通用的RDM指导方针通常不能解决实际问题,并且没有适当的上下文,规程最佳实践可能会压倒一切。一旦制定了指导方针,扩大其影响范围并使其保持最新是具有挑战性的。RDMkit是一个开放的社区主导的资源,被设计为获取生命科学中丰富的RDM知识、工具、培训和资源的门户。RDMkit提供了关于数据管理员和研究人员期望的常见RDM任务的最佳实践指南,来自生命科学领域的特定数据管理挑战和解决方案,以及展示支持研究数据生命周期的整体解决方案的工具集。RDMkit建立在可重用的开放基础设施之上,允许组织使用它作为蓝图创建自己的指导方针。

The cost of unmodeled biological complexity in artificial neural networks. 人工神经网络中未建模生物复杂性的代价。
IF 7.4 Q1 COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE Pub Date : 2025-08-15 eCollection Date: 2025-10-10 DOI: 10.1016/j.patter.2025.101343

We propose the theories of pragmatism and functionalism to differentiate between artificial neural networks (ANNs) and biological neural networks (BNNs). While ANNs emulate some cell structures and function approximation mechanisms, questions remain about their ability to emulate intelligent behavior observed in BNNs. We propose that relying solely on biological structures suitable for function approximation may overlook pivotal aspects of ANNs' development, limiting their potential to emulate robust intelligence. Specifically, we investigate the role of ion channels in biological neurons and the randomness they introduce. This randomness seems to be vital for spike generation, although it is not directly related to function approximation. We conclude that structures, which do not directly contribute to function approximation, play a significant role in controlled activity, such as behavior, and should be integrated more into the controlled activity of artificial systems.

我们提出实用主义和功能主义的理论来区分人工神经网络(ann)和生物神经网络(bnn)。虽然人工神经网络模拟了一些细胞结构和功能近似机制,但它们模拟在生物神经网络中观察到的智能行为的能力仍然存在问题。我们认为,仅仅依赖于适合于函数近似的生物结构可能会忽略人工神经网络发展的关键方面,限制了它们模拟鲁棒智能的潜力。具体来说,我们研究了离子通道在生物神经元中的作用及其引入的随机性。这种随机性似乎对脉冲产生至关重要,尽管它与函数近似没有直接关系。我们得出的结论是,不直接有助于功能近似的结构在受控活动(如行为)中发挥重要作用,并且应该更多地集成到人工系统的受控活动中。
