NASA's Perseverance rover has found complex carbon in rocks on Mars. Scientists believe these findings could be signs of ancient microbial life. The rover detected these organic (有机的) carbon components in Red Planet rocks. While this does not prove that life existed on Mars, it suggests the planet once had the building blocks of life. Mars was likely more friendly to life billions of years ago. Experts are excited but remain cautious. They need to study more rock samples to be sure. This discovery helps us understand if basic life is common in the universe.NASA 火星车探测到古代微生物生命的潜在迹象。美国宇航局（NASA）的‘毅力号’火星车在火星岩石中发现了复杂碳。科学家认为这些发现可能是古代微生物生命的迹象。火星车是在这颗红色星球的岩石中探测到这些有机碳成分的。虽然这并不能证明火星上曾经存在生命，但它表明该星球曾拥有生命的基本构件。数十亿年前，火星可能对生命更为友好。专家们很兴奋，但也保持着谨慎。他们需要研究更多岩石样本才能确定。这一发现有助于我们了解宇宙中是否存在普遍的基础生命。（来源：Slashdot）---[01:06] Google keeps losing top AI researchers to rivals. Google is losing its top AI researchers to rival (竞争对手，对抗的) companies. Recent reports show key figures behind the Gemini AI model plan to leave Google. Jonas Adler and Alexander Pritzel are moving to Anthropic. Adler worked on AI coding, while Pritzel worked on model training. Also, Nobel laureate John Jumper recently joined Anthropic, and Gemini leader Noam Shazeer left for OpenAI. These departures (离开，人员离职) worried investors and caused Alphabet's stock to drop. Anthropic and OpenAI can offer large equity (股权，股本) packages because they are close to going public. DeepMind engineers are moving to Anthropic eleven times more often than the other way around. However, Google's CEO Demis Hassabis insists Google still has a very strong research team.谷歌持续流失顶尖 AI 研究人员至竞争对手。谷歌正流失顶尖 AI 研究人员到竞争对手公司。近期报告显示，Gemini AI 模型背后的几位核心人物计划离开谷歌。乔纳斯·阿德勒（Jonas Adler）和亚绿山大·普里茨尔（Alexander Pritzel）正准备加入 Anthropic。阿德勒此前负责 AI 编程工作，而普里茨尔负责模型训练。此外，诺贝尔奖得主约翰·江珀（John Jumper）最近也加入了 Anthropic，而 Gemini 负责人诺姆·沙泽尔（Noam Shazeer）则跳槽到了 OpenAI。这些人员离职令投资者感到担忧，并导致 Alphabet 股价下跌。由于 Anthropic 和 OpenAI 都接近上市，它们能够为员工提供丰厚的股权激励包。分析显示，DeepMind 工程师跳槽到 Anthropic 的频次是反向跳槽的 11 倍。不过，谷歌 DeepMind 首席执行官德米斯·哈萨比斯（Demis Hassabis）坚称，谷歌依然拥有极其强大的研究团队。（来源：The Decoder）---[02:02] European cities use design solutions to fight extreme heat. Europe is facing a very hot summer with record temperatures. Cities are using design solutions to help citizens stay cool. For example, Paris created cool zones called cooling islands. These areas use water, vegetation (植被，草木), and shade to reduce heat. They can make a space four to seven degrees cooler. Paris now has over one thousand four hundred cooling spots. Residents can find them on a digital map. French schools are painting windows with chalk powder mixed with water to reflect sunlight. In Marseilles, the city is planting thousands of trees. Trees cool the air naturally by blocking the sun and releasing water from their leaves. This design intervention (干预，介入手段) helps lower urban heat.欧洲城市利用设计方案应对极端高温。欧洲正面临一个创纪录的炎热夏天。各个城市正在利用设计方案来帮助市民保持凉爽。例如，巴黎创建了被称为“冷却岛”的避暑区域。这些区域利用水、植物和遮阴来减少热量。它们可以让空间温度降低 4 到 7 华氏度。巴黎目前拥有 1400 多个冷却点，居民可以在数字地图上找到它们。法国学校正用粉笔粉混水涂刷窗户，以反射阳光。在马赛，该市正在种植成千上万棵树木。树木通过阻挡阳光和从叶子中释放水分来自然冷却空气。这种设计干预手段有助于降低城市热量。（来源：Fast Company Co.Design）---[02:50] 📚 今日单词：rival- noun/adjective 竞争对手，对抗的- [ˈraɪvl]- 词源：From Latin 'rivalis' (one who uses the same stream as another, competitor).---[02:55] 词组/例句- rival companies 竞争对手公司- Google is losing its top AI researchers to rival companies. 谷歌正流失顶尖 AI 研究人员到竞争对手公司。---[03:11] That's all for today's Daily Tech Briefing.
