同期发表的论文中，美国加州大学旧金山分校团队在接受联合免疫疗法后实现HIV-1复制控制的个体 中，发现了与病毒抑制相关的免疫特征。尽管该试验未设对照组，无法对联合免疫疗法的疗效作出确切 结论，但团队识别出T细胞中与病毒控制相关的特征，这些特征存在于治疗后病毒反弹较慢的个体中。 德国柏林夏里特医学院报告了一例通过干细胞移植实现HIV-1缓解的病例，其供体细胞仅携带一个突变 受体基因拷贝（CCR5 Δ32杂合子）。患者2009年确诊HIV感染，2015年发展为急性髓系白血病。由于 未能找到纯合子CCR5 Δ32供体，患者接受了异基因干细胞移植治疗癌症。移植3年后患者停用抗逆转录 病毒疗法，移植6年后检测未发现HIV-1复制迹象。 在第38个世界艾滋病日当天，《自然》杂志发表论文报道了德国一名60岁男性通过干细胞移植实现艾滋 病病毒（HIV）感染症状持续缓解的案例，这是迄今已知的第七例。该患者移植的细胞仅携带一个突变 基因拷贝（该基因编码HIV-1感染所需蛋白质），与先前的两拷贝突变细胞实现缓解的案例不同。这表 明具有消除HIV潜力的干细胞供体群体，可能比此前预想的更为广泛。 此前六例通过癌症干细胞移植实现HIV清 ...

Core Insights - NASA and the University of Arizona's Lunar and Planetary Laboratory have detected trace amounts of tryptophan, an essential amino acid, in pristine samples from the asteroid Bennu, providing significant evidence for the hypothesis that the building blocks of life on Earth may originate from space [1][2] Group 1 - The asteroid Bennu, formed 4.6 billion years ago, has remained largely unchanged since the birth of the solar system, and NASA's OSIRIS-REx mission collected samples from its surface in 2020 for analysis [1] - Previous studies identified 33 amino acids in Bennu samples, with 14 of them being utilized by Earth life to construct proteins; the recent study confirms the presence of these 14 amino acids and detects trace amounts of tryptophan [1] - Tryptophan is significant as it is one of the more complex amino acids and is essential for human health, as it cannot be synthesized by the body and must be obtained through diet; this is the first detection of tryptophan in any meteorite or space sample [1] Group 2 - Researchers also detected five nucleobases, which are key components of DNA and RNA, indicating that both amino acids and nucleobases coexist in the same pristine celestial body [2] - The formation of these life precursor molecules is believed to be related to an ancient "hydration chemical factory," with Bennu samples containing abundant layered silicates that can only form in the presence of liquid water [2] - The presence of liquid water in Bennu's parent body suggests that it may have been rich in ammonia and other chemical components that could catalyze the gradual formation of amino acids and nucleotides from simple interstellar materials [2]

Core Insights - A new study from Princeton University reveals a key mechanism that allows the human brain to maintain an advantage over artificial intelligence (AI): the brain reuses cognitive "modules" across different tasks, enabling rapid construction of new behavior patterns [1][2] Group 1: Cognitive Flexibility - Advanced AI models can surpass human performance on single tasks but struggle with learning and executing multiple tasks due to a lack of cognitive flexibility [1] - Humans can easily adapt to new information or unfamiliar challenges, such as learning new software or following a recipe, while AI finds "instant" learning difficult [1] Group 2: Research Findings - The study trained two male rhesus monkeys on three related classification tasks, recording their brain activity during the process [2] - The tasks involved judging whether a blurred image resembled a rabbit or the letter "T," or determining if a color was closer to red or green, with varying degrees of image blurriness [2] - Analysis revealed that the prefrontal cortex contains several reusable activity patterns corresponding to different cognitive "blocks," allowing the brain to flexibly combine these blocks to construct new behaviors [2] Group 3: Implications for AI and Mental Health - The prefrontal cortex also suppresses certain cognitive modules when they are not needed, helping the brain focus on the current task, as cognitive resources are limited [2] - This modular and reconfigurable learning approach may explain how humans efficiently learn new skills without forgetting old ones, contrasting with AI systems that often face "catastrophic interference" [2] - Incorporating the brain's modular mechanism into AI could lead to the development of intelligent systems capable of continuous learning without forgetting [2]
