12月4日清晨，在天津大学脑机海河实验室与天津市环湖医院合作的全国首个脑机接口综合临床实验病 区里，一台搭载脑机接口技术的监测设备上，实时显示着患者颅内压力变化。而在过去，要想获取这样 的数据，往往意味着需要进行一次开颅手术。 在这里，脑机接口已不是科幻作品里的"黑科技"，而是融入日常诊疗的关键工具。从实验室到临床病 房，从基础研究到产业推进，天津大学脑机海河实验室团队将脑机接口技术以一种温润而坚定的方式守 护着人民的健康。该校医学部副主任、脑机海河实验室副主任刘秀云教授说："实验病区引入脑机接口 和智能医学技术，让医工融合科技真正落到了医疗服务场景中。" "我很幸运能赶上国家科技创新加速奔跑的时代。"刘秀云回忆起2021年回国任教的那一年，恰逢脑机接 口在全球范围进入"加速期"。作为我国神经重症医学与生物医学工程交叉领域的青年学者，她几乎把生 活过成"分秒制"，在实验室、病房和会议室之间，经常看到她一路小跑的身影。 《中共中央关于制定国民经济和社会发展第十五个五年规划的建议》提出，"前瞻布局未来产业，探索 多元技术路线、典型应用场景、可行商业模式、市场监管规则"。刘秀云说，早在"十四五"时期，团队 就将目光 ...

10日，记者从合肥综合性国家科学中心大健康研究院获悉，该院曹灿、王春玉团队联合中国科学技术大 学薛天团队、天津医科大学陈贺团队等，提出一种快速抗抑郁新策略，并设计出候选化合物 TMU4142，该化合物在动物实验中呈现显著的快速抗抑郁效果，且无明显副作用，为研发新一代快速 抗抑郁药物提供了新思路。相关成果日前在线发表于国际期刊《细胞》。 在研发过程中，研究团队注意到前人研究中报道不同脑区血清素1A受体，在下游信号传递中会"偏 好"结合不同G蛋白类型来发挥功能，中缝背核受体主要与Gi3蛋白结合，而海马体及皮质区的受体则主 要结合GoA蛋白。团队据此提出新策略：设计一种"偏好"激活GoA蛋白的化合物，在维持对GoA蛋白激 活能力的同时，弱化其对Gi3蛋白的激活，从而精准调控有益通路、规避延迟起效的有害效应。 研究团队以具有部分GoA蛋白激活特性的老药Pindolol为参考分子骨架，优化并合成了新候选化合物 TMU4142。在新奇食物抑制实验中，TMU4142注射1小时即可改善小鼠抑郁状态。神经化学检测进一步 证实，该化合物在治疗剂量下不会引发中缝背核区域自身受体介导负反馈作用。 曹灿表示，团队下一步将持续优化化合物 ...

据美国卡内基梅隆大学人机交互研究所官网最新消息，该机构针对主流大模型的研究发现，人工智能 （AI）在变得更"智能"的同时，其行为也变得更加"自私"。研究表明，具备推理能力的大型语言模型， 在社会互动中表现出更强的自我利益倾向，合作意愿更低，甚至可能对群体协作产生负面影响。这也意 味着，模型的推理能力越强，其合作性反而越弱。当人们借助AI处理人际关系冲突、婚姻问题或其他 社会性议题时，这类模型更可能提供鼓励"以自我为中心"的建议。 实验中，两个版本的ChatGPT被置于博弈情境：每个模型初始拥有100分，可选择将全部分数投入共享 池，或保留分数独享。结果显示，非推理模型在96%的情况下选择共享，而推理模型的分享率仅为 20%。仅增加五到六个推理步骤，合作行为就下降了近一半。 在群体实验中，当推理型与非推理型模型共同协作时，结果更为严峻。推理模型的自私行为表现出明显 的传染效应，导致原本倾向合作的非推理模型整体表现下降81%。这表明，高智能AI的个体决策不仅影 响自身，还可能破坏整个群体的协作生态。 这一发现对人机交互的未来发展具有深远意义。用户往往更信任"更聪明"的AI，容易采纳其看似理性的 建议，并以此为自身 ...
