“认知卸载”,人类大脑会陷入舒适区吗
Ke Ji Ri Bao· 2025-12-10 01:01
美国纽约州立大学石溪分校教授劳伦·里士满说:"AI本身不一定让我们变笨,只是我们与它互动的 方式可能很笨。"那么,人类在使用生成式人工智能(AI)时犯了哪些错?又该如何改变习惯,让技术 真正为人所用? 17世纪法国哲学家、数学家布莱兹·帕斯卡尔曾言:"人是一根会思考的芦苇。"人的全部尊严,便 在于思想。然而,当ChatGPT能一秒钟生成一篇论文,当Claude能瞬间梳理出复杂的逻辑脉络,一个疑 问开始出现:这根"会思考的芦苇"是否正在枯萎?人类是否正为了便利,主动交出自己的思考权? 减轻思维负担带来恶性循环 据英国《新科学家》网站报道,生成式AI正深度融入人们生活,并让人延续了"认知卸载"的传统, 即利用工具减轻思维负担。就像人们不是用脑子记住要买什么,而是写一份购物清单一样。但相比苏格 拉底当年对写清单的担忧,AI带来的挑战远甚于此。 里士满与其同事今年3月在《自然》杂志发表论文指出,认知卸载会对认知造成负面影响。过度依 赖AI不仅让学习过程变得被动和肤浅,更会导致恶性循环。人们卸载得越多,独立思考的能力就越 弱,进而更加依赖工具。 英国苏塞克斯大学哲学家安迪·克拉克对此持辩证态度。他提出的"延伸心灵"理论 ...

动物实验显示:新疫苗能预防严重过敏长达一年
Ke Ji Ri Bao· 2025-12-10 00:34
该疫苗靶向一种名为免疫球蛋白E(IgE)的抗体。正常情况下,IgE随血液流动,会与体内免疫细胞结 合,在遭遇病毒、寄生虫等威胁时触发免疫应答,释放组胺,引发咳嗽、喘息或荨麻疹等症状。在过敏 人群中,IgE会对花生、猫毛屑等原本无害的蛋白过度反应,甚至可能诱发致命的全身性过敏反应,导 致喉头水肿、呼吸衰竭甚至休克。 新疫苗能够促使机体生成可与IgE结合的抗体,从而阻止IgE与免疫细胞受体结合。这一机制显著降低了 接触过敏原后可能启动过敏反应的游离IgE水平。 法国图卢兹感染与炎症研究所科学家在新一期《科学·转化医学》杂志发表论文称,他们研发出一种新 的实验性疫苗,名为"IgE-K",能使小鼠在长达一年时间内免于严重过敏反应。这一最新进展显示,疫 苗接种在预防过敏领域具有广阔前景。 该研究证实了疫苗可激发抗IgE抗体的产生。新疫苗的作用机制与已获批准的抗过敏单抗药物奥马珠单 抗类似,但后者需每两周注射一次以维持效果,而新疫苗有望提供更持久的保护。 不过团队也提醒,仍需进一步验证该疫苗是否会在人体内引发意外过敏反应,以及IgE长期降低是否会 削弱机体对抗寄生虫感染的能力。 (文章来源:科技日报) 在动物实验中,团队 ...
