Hacking the atmosphere: geoengineering gets a reality check

黑客入侵大气层：地球工程面临现实考验

Solar geoengineering, the controversial idea that we could deliberately intervene in the climate system to counteract global warming, is moving beyond computer simulations and into the practical engineering challenges required to make it real. Researchers are now working on aircraft, materials, and other systems for solar geoengineering. But as they delve into these details, they’re finding that even early deployment would require significant new infrastructure, time, and investment. Find out what happens when solar geoengineering encounters the realities of trying to cool the planet. —James Temple, MIT Technology Review 太阳地球工程是一个充满争议的构想，即通过人为干预气候系统来抵消全球变暖。目前，该领域正从计算机模拟转向实现这一构想所需的实际工程挑战。研究人员正在开发用于太阳地球工程的飞机、材料及其他系统。然而，随着研究深入，他们发现即使是早期的部署也需要大量的新基础设施、时间和投资。了解当太阳地球工程遭遇试图为地球降温的现实时会发生什么。——James Temple，《麻省理工科技评论》

Narrated: inside interoception, the hidden sense of how you feel inside

语音版：走进“内感受”，感知内在状态的隐藏感官

Scientists have a word for how we sense ourselves from the inside: interoception. Today, thanks to a 2021 Nobel Prize and new tools that can map internal signaling across the body, research into interoception is taking off. As researchers decode how signals move between body and brain, a clearer picture is starting to take shape—with implications for how we treat conditions from obesity to anxiety. —Katherine W. Isaacs 科学家们用一个词来描述我们从内部感知自身的方式：内感受（Interoception）。如今，得益于2021年的诺贝尔奖以及能够绘制全身内部信号图谱的新工具，内感受研究正在蓬勃发展。随着研究人员解码信号如何在身体和大脑之间传递，一幅更清晰的图景正在形成，这将对我们治疗从肥胖到焦虑等各种疾病产生深远影响。——Katherine W. Isaacs

This is the reason Demis Hassabis started DeepMind 这就是 Demis Hassabis 创办 DeepMind 的原因

Watching DeepMind’s AI master the ancient board game Go, Demis Hassabis realized that his company was ready to take on one of the most important and complicated puzzles in biology: predicting the structure of proteins. The result was AlphaFold2, an AI that could predict the shape of proteins down to the nearest atom. “It’s the most complex thing we’ve ever done,” Hassabis told MIT Technology Review. Taking on scientific problems is the culmination of what Hassabis set out to achieve, and it’s what he wants to be known for. “This is the reason I started DeepMind,” he says. “In fact, it’s why I’ve worked my whole career in AI.” Discover how he plans to transform science with AI. —Will Douglas Heaven 在目睹 DeepMind 的 AI 掌握了古老的围棋游戏后，Demis Hassabis 意识到他的公司已经准备好挑战生物学中最重要、最复杂的难题之一：预测蛋白质结构。其成果便是 AlphaFold2，这是一种能够精确到原子级别预测蛋白质形状的 AI。“这是我们做过的最复杂的事情，”Hassabis 告诉《麻省理工科技评论》。攻克科学难题是 Hassabis 奋斗目标的巅峰，也是他希望被世人铭记的原因。“这就是我创办 DeepMind 的原因，”他说，“事实上，这也是我整个职业生涯致力于 AI 的原因。”探索他如何计划用 AI 改变科学。——Will Douglas Heaven
