Claude Science is Anthropic’s newest flagship product. At an event for pharmaceutical executives, biotech founders, and researchers yesterday, Anthropic announced Claude Science, a major new product intended to support scientific research like Claude Code supports software engineering. Claude Science 是 Anthropic 最新的旗舰产品。在昨天为制药高管、生物技术创始人和研究人员举办的活动中，Anthropic 发布了 Claude Science。这是一款重要的新产品，旨在像 Claude Code 支持软件工程一样，为科学研究提供支持。

Like Claude Code, Claude Science can autonomously carry out meaningful work from concise, high-level instructions, with tools for computational biology and drug development. The launch signals that Anthropic is doubling down on AI for science, and the company will also use the product in its own research into drugs for rare, neglected diseases. Discover why Anthropic is betting big on AI for scientific research. —Grace Huckins 与 Claude Code 一样，Claude Science 可以根据简洁的高级指令自主开展有意义的工作，并配备了用于计算生物学和药物开发的工具。此次发布标志着 Anthropic 正在加码 AI 科学研究，该公司也将利用该产品进行罕见病和被忽视疾病的药物研究。了解为何 Anthropic 在 AI 科学研究上押下重注。——Grace Huckins

Why California’s carbon manure math doesn’t add up. Something stinks in California’s climate policies. Years ago, the state set up a system that pays cattle farmers to turn the methane emitted from cattle manure into natural gas. It’s become wildly popular because the subsidies are extremely lucrative. 为什么加州的碳排放“粪便数学”算不明白？加州的气候政策里透着一股“臭味”。多年前，该州建立了一套系统，向养牛户支付费用，将牛粪排放的甲烷转化为天然气。由于补贴极其丰厚，该项目变得非常受欢迎。

But research suggests the program exposes the shortcomings of carbon offsetting and trading schemes. Instead of forcing industries to directly cut their pollution or pay for it as a cost of doing business, legislators have opted for incentives that swap climate responsibilities between parties and regions. The system could ultimately lock in more warming. Read the full story on California’s dubious carbon calculations. —James Temple 但研究表明，该计划暴露了碳抵消和交易机制的缺陷。立法者没有强制行业直接削减污染或将其作为经营成本支付，而是选择了通过激励措施，在各方和各地区之间交换气候责任。该系统最终可能会导致更多的全球变暖。阅读关于加州可疑碳计算的完整报道。——James Temple

Watch now: longevity’s next frontier—“reprogramming” your body. Billions of dollars are pouring into efforts to reverse aging as scientists investigate ways to return cells to a younger state. But how close are these experimental treatments? And are they likely to work? At a recent virtual Roundtables event, MIT Technology Review explored the answers with science editor Mary Beth Griggs and senior biotechnology reporter Jessica Hamzelou. Subscribers can now watch the full recording of the fascinating discussion. 立即观看：长寿的下一个前沿——“重编程”你的身体。随着科学家们探索让细胞恢复到年轻状态的方法，数十亿美元正涌入逆转衰老的领域。但这些实验性疗法距离现实还有多远？它们真的有效吗？在最近的一次虚拟圆桌会议上，《麻省理工科技评论》与科学编辑 Mary Beth Griggs 和资深生物技术记者 Jessica Hamzelou 一起探讨了这些问题的答案。订阅用户现在可以观看这场精彩讨论的完整录像。

MIT Technology Review Narrated: the search for dark matter has been blown wide open. For decades, physicists have hunted for weakly interacting massive particles (WIMPs), a leading candidate for dark matter. But their search has run into a new problem: neutrinos. These tiny particles from the sun and other stars can create a “neutrino fog” that drowns out any signal of dark matter. 《麻省理工科技评论》音频版：寻找暗物质的探索被彻底打开。几十年来，物理学家一直在寻找弱相互作用大质量粒子（WIMPs），这是暗物质的主要候选者。但他们的搜索遇到了一个新问题：中微子。这些来自太阳和其他恒星的微小粒子会产生一种“中微子雾”，掩盖掉任何暗物质信号。

Hitting the neutrino fog does not, however, mean an end to the search. Researchers just have to shift the focus of their hunt. They’re now casting a much wider net. New proposals include quantum sensors, liquid-helium detectors, and even searches in Jupiter’s atmosphere. —Dan Garisto 然而，遇到“中微子雾”并不意味着搜索的终结。研究人员只需要改变搜索重点。他们现在正在撒下更大的网。新的提议包括量子传感器、液氦探测器，甚至在木星大气层中进行搜索。——Dan Garisto
