November 19, 2025312 社交生活可能是长寿的秘籍The Italian island of Sardinia has more than six times as many centenarians as the mainland and ten times as many as North America. Why? According to psychologist Susan Pinker, it's not a sunny disposition or a low-fat, gluten-free diet that keeps the islanders healthy -- it's their emphasis on close personal relationships and face-to-face interactions. Learn more about super longevity as Pinker explains what it takes to live to 100 and beyond.意大利撒丁岛上的百岁老人是大陆的六倍多,也是北美的十倍。这是为什么呢?根据心理学家苏珊·平克(Susan Pinker)的研究,使得那里的人们长寿的,既不是阳光普照,也不是低脂无糖饮食,而是他们对亲密关系和面对面互动关系的重视。想要了解怎样长寿,就看看平克是解释如何才能活到百岁及百岁以上的。在她获得奖项的著作《性别悖论》(The Sexual Paradox) 中,平克提出,生物差异可能在形成课堂、人生历程和职场性别差距方面具有超乎想象的影响力。而在其著作《村落效应》(The Village Effect) 中,她则探讨了另一股潮流:社交性的、面对面的互动不仅对我们的幸福感至关重要,对我们的生存也同样关键;同时,她也阐述了技术如何可能使我们与这些维系生命的纽带隔绝开来。正如她所写:“疏于与对你重要的人保持紧密联系,其对健康的危害至少等同于每天抽一包烟的习惯、高血压或肥胖。”除了著书立说,平克还为《华尔街日报》撰写专栏“思想与物质世界”(Mind and Matter),该专栏旨在揭示人类行为研究中的惊人进展。平克的大量文章(包括她的每周专栏“问题解决”(Problem Solving) 和“商业头脑”(The Business Brain))曾发表于《卫报》、《纽约时报》、《金融时报》等众多媒体。海伦・沃尔特斯(Helen Walters)是TED 的内容策划负责人。...more16minPlay
November 18, 2025311 TED-ED 学术研究由公众资助——为何公众却无法获得In the US, your taxes fund academic research at public universities. Why then do you need to pay expensive, for-profit journals for the results of that research? Erica Stone advocates for a new, open-access relationship between the public and scholars, making the case that academics should publish in more accessible media to help the public be well-educated and well-informed. [Directed by Jeff Le Bars, JetPropulsion.space, music by Salil Bhayani, cAMP Studio].在美国,你纳的税被用来资助大学的学术研究。可为什么你还需要再付款给营利性期刊来获取这些研究成果呢?埃丽卡・斯通(Erica Stone)倡导一种公众与学者间新型的公开获取的关系,即学者们应该在大众更易获取信息的媒体上发表成果,从而帮助提高公众的受教育程度和知情程度。[导演:Jeff Le Bars,JetPropulsion.space, 音乐制作:Salil Bhayani,cAMP Studio]通过协作项目,埃丽卡・斯通为学者、学生和社区成员创造机会,让他们参与对话及公民问题解决,旨在构建一个更公平公正的民主制度。作为研究者,她热衷于让学术研究成果免费且易于获取。...more5minPlay

November 12, 2025306 看不见的海洋驱动者Oceanographer Penny Chisholm introduces us to an amazing little being: Prochlorococcus, the most abundant photosynthetic species on the planet. A marine microbe that has existed for millions of years, Prochlorococcus wasn't discovered until the mid-1980s -- but its ancient genetic code may hold clues to how we can reduce our dependence on fossil fuels.海洋学家彭妮・奇肖尔姆(Penny Chisholm)向我们介绍了一种神奇的小生物:原绿球藻,地球上最丰富的光合作用物种。尽管这种微生物已经存在了数百万年,却直至1980年代才被发现——但它的远古基因代码可能包含了我们如何减少化学燃料依赖的密码。彭妮・奇肖尔姆(Penny Chisholm,其学术著作以萨莉・奇肖尔姆 / Sallie Chisholm 为署名)从本科时期起就致力于研究一种名为浮游植物的微型植物。20 世纪 80 年代加入麻省理工学院(MIT)教职后,她有幸参与发现了地球上体型最小、数量最丰富的浮游植物 —— 原绿球藻(Prochlorococcus)。这种微小的光合微生物宽度不足人类头发丝的 1/100,在全球海洋大片光照充足的表层水域中大量繁殖,利用太阳能释放氧气、消耗二氧化碳并实现生长。全球海洋中这类微小细胞的数量估计高达 3×10²⁷个,它们为其他微生物提供营养,是海洋食物网的能量基础。“30 多年来,原绿球藻一直是我的灵感源泉,” 奇肖尔姆表示,“它让我深刻认识到光合作用在塑造地球过程中的作用,以及生物多样性的力量。最重要的是,它让我对自然界令人惊叹的复杂性心怀谦逊。”奇肖尔姆是 MIT 十位学院教授(Institute Professors,MIT 最高荣誉教职)之一,其关于原绿球藻的研究获得了众多荣誉,包括 2011 年由奥巴马总统在白宫颁发的国家科学奖章(National Medal of Science)。她还与人合著了一系列儿童书籍,讲述光合作用在塑造世界过程中的作用。...more17minPlay
