This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology. These startups hope “blended” food will cut our appetite for red meat. In the fall of 2025, Jeff Dodge served hungry students steaming marinara sauce and meatballs. The students loved them: 92% of those who tried them wanted them on the menu. Few could guess that mushrooms had been mixed into the meat. Dodge was testing a new product called 50/Cut from the company Joyn. The blend of seemingly simple ingredients—available as meatballs, burgers, and ground meat—could help solve one of the biggest challenges of the climate crisis: getting people to eat less meat, particularly beef. Joyn is among a wave of startups creating “blended meat,” which combines plant proteins with the real deal. The logic: The best meat replacement is … better meat. Get a taste of the startups betting on greener beef. —Meghan McCarron

这是《下载》的今日版，这份工作日通讯为您提供每日科技动态。这些初创公司希望“混合”食品能减少我们对红肉的胃口。2025年秋天，杰夫·道奇（Jeff Dodge）为饥肠辘辘的学生们端上了热气腾腾的意式番茄酱肉丸。学生们非常喜欢：92%的试吃者希望将其列入菜单。很少有人能猜到肉里混合了蘑菇。道奇当时正在测试Joyn公司的一款名为“50/Cut”的新产品。这种看似简单的配料混合物（有肉丸、汉堡和肉馅等形式）有助于解决气候危机中最大的挑战之一：让人们少吃肉，尤其是牛肉。Joyn是众多创造“混合肉”的初创公司之一，这种肉将植物蛋白与真肉结合在一起。其逻辑是：最好的肉类替代品就是……更好的肉。来品尝一下那些押注于更环保牛肉的初创公司吧。——梅根·麦卡伦（Meghan McCarron）

This implant can restore sight for patients with macular degeneration. More than 5 million people have an advanced form of age-related macular degeneration (AMD) called geographic atrophy, in which retinal cells die off. Until now, no treatment could restore their vision. A system called PRIMA changes that. It combines a retinal implant with camera-equipped eyeglasses to improve sight in patients who develop a blind spot in the middle of their vision. After training sessions, more than 80% of recipients could read, do crosswords, and use their phones. Find out how the sight-restoring implant works. —Linda Marsa

这种植入物可以恢复黄斑变性患者的视力。超过500万人患有一种被称为“地图样萎缩”的晚期年龄相关性黄斑变性（AMD），在这种疾病中，视网膜细胞会死亡。到目前为止，还没有任何治疗方法可以恢复他们的视力。一种名为PRIMA的系统改变了这一现状。它将视网膜植入物与配备摄像头的眼镜相结合，以改善视力中心出现盲点的患者的视力。经过培训后，超过80%的接受者能够阅读、做填字游戏并使用手机。了解这种恢复视力的植入物是如何工作的。——琳达·马萨（Linda Marsa）

MIT Technology Review Narrated: The agentic web is here. In 2001, a decade after inventing the World Wide Web, Tim Berners-Lee articulated a new vision: an internet navigated by autonomous software agents that address our every need, without requiring us to muck about with browsers and search engines ourselves. At the time, the idea seemed far-fetched. But a quarter-century on, AI agents are beginning to make it a reality. They can triage your inbox, do your grocery shopping, and even access your bank accounts. This new era is being called the agentic web, and it will inevitably transform the internet. Whether the human web survives this transition is anyone’s guess. This is our latest story to become an MIT Technology Review Narrated podcast, which we publish each week on Spotify and Apple Podcasts.

《麻省理工科技评论》播客：代理式网络时代已来。2001年，在发明万维网十年后，蒂姆·伯纳斯-李（Tim Berners-Lee）阐述了一个新愿景：一个由自主软件代理导航的互联网，它们能满足我们的每一个需求，而无需我们亲自摆弄浏览器和搜索引擎。当时，这个想法似乎遥不可及。但四分之一个世纪过去了，人工智能代理正开始将其变为现实。它们可以整理你的收件箱、代你购买杂货，甚至访问你的银行账户。这个新时代被称为“代理式网络”，它将不可避免地改变互联网。人类网络能否在这次转型中幸存，谁也说不准。这是我们最新一期《麻省理工科技评论》播客故事，我们每周在Spotify和Apple Podcasts上发布。只需在任一平台上导航至“MIT Technology Review Narrated”，并关注我们，即可在内容发布时获取所有最新资讯。
