Cloudflare Announces Global Workforce Reduction of Over 1,100 Employees for Agentic AI Era Transition

    Cloudflare has announced a global workforce reduction of more than 1,100 employees via an internal email to its entire global team. The company clarifies the move is not a cost-cutting exercise or individual performance assessment, but a strategic restructuring to align its operations with the agentic AI era, as its internal AI usage has surged over 600% in the past three months. Cloudflare will provide departing employees with industry-leading severance packages, including full base pay through 2026, extended US healthcare coverage, and equity vesting through August 15 even for those who haven’t hit their one-year cliffs. The leadership states the one-time decisive cut aims to avoid prolonged employee uncertainty caused by repeated small layoffs or drawn-out reorganizations. Cloudflare will share more details in its upcoming earnings call and internal all-hands meeting, and expressed gratitude to departing staff for their meaningful contributions.

Cloudflare宣布全球裁员超1100人 推进智能AI时代转型

    Cloudflare通过致全球全体员工的内部邮件宣布将全球裁员超1100人。该公司明确此举并非成本削减措施或个人绩效评估，而是为适配智能AI时代调整运营的战略重组，过去三个月其内部AI使用量激增超600%。Cloudflare将为离职员工提供行业领先的遣散方案，包括截至2026年底的全额基本工资、美国员工的延长医保覆盖，以及即使未达到一年归属期也可享有的截至8月15日的股权归属。管理层表示本次一次性果断裁员旨在避免反复小幅裁员或拖沓重组给员工造成的长期不确定性。Cloudflare将在即将到来的财报电话会和内部全员会上披露更多细节，并对离职员工的重要贡献表示感谢。

New Simulations Show the Antarctic Circumpolar Current Didn't Form Overnight

    New simulations from Germany's Alfred Wegener Institute (AWI) reveal the Antarctic Circumpolar Current (ACC) didn't form overnight, requiring multiple aligned factors. The ACC, five times stronger than the Gulf Stream, circulates clockwise around Antarctica and feeds global ocean conveyor belts. Previous assumptions held Australia and South America's northward drift (opening ocean passages) was sufficient, but new data shows strong westerly winds aligning with the Tasman Gateway via Australia's further north shift were critical. The simulations model Earth 33.5 million years ago, when the planet transitioned from a greenhouse to icehouse climate, finding a proto-ACC failed to complete full circuits until wind and gateway aligned. The fully formed ACC protects Antarctic ice sheets by blocking warm waters, but modern climate change may weaken it 20% by 2050 via freshwater melt dilution, creating a vicious ice-loss cycle. Lead researcher Hanna Knahl notes past climate simulations inform future predictions but can't be mapped 1:1, as the infant ACC functioned differently than today's.

新模拟显示南极绕极流并非一夜形成

    德国阿尔弗雷德·魏格纳研究所（AWI）的新模拟显示，南极绕极流（ACC）并非一夜形成，需多个条件协同作用。南极绕极流强度是墨西哥湾流的5倍，顺时针环绕南极流动，为全球海洋输送带提供动力。此前认为澳大利亚和南美洲北移（打开海洋通道）已足够，但新数据表明，强西风带随澳大利亚进一步北移与塔斯曼海道对齐才是关键。模拟针对3350万年前地球从温室气候向冰室气候过渡的时期，发现原型南极绕极流在风与海道对齐前无法完成完整环流。完全形成的南极绕极流通过阻隔暖水保护南极冰盖，但现代气候变化可能通过融水稀释使其到2050年减弱20%，形成冰损失的恶性循环。首席研究员汉娜·克纳尔指出，过去气候模拟可为未来预测提供参考，但不能1:1映射，因早期南极绕极流的作用与现今不同。

Artemis II Astronauts Witness Meteorite Impacts on Moon During Historic Flyby

    NASA's Artemis II mission astronauts, who broke the record for the farthest distance from Earth during their flyby, observed multiple meteorite impact flashes on the lunar surface during the first human lunar journey in over half a century. The crew reported a total of six impact flashes, described as brief millisecond-long white to bluish-white pinpricks of light, during their nearly seven-hour lunar observation period. Most of these sightings occurred during a solar eclipse on April 6, 2026, when the Moon was backlit by the Sun and visible only to the Artemis II crew. NASA scientists expressed delighted surprise at the observations, as the crew was not widely expected to spot such impacts during the mission. Ground teams are now cross-referencing the crew's observations with data from lunar orbit satellites to study impact frequency and projectile size. Experts note the findings highlight the need for closer monitoring of lunar meteor flux before establishing a lunar base, since the Moon lacks an atmosphere to burn up small incoming objects.

阿尔忒弥斯二号宇航员在历史性飞掠期间目击月球陨石撞击

    美国国家航空航天局（NASA）阿尔忒弥斯二号任务的宇航员在飞掠期间打破了人类距地球最远飞行纪录，他们在时隔半个多世纪的首次人类月球航行期间，观测到月球表面多次陨石撞击的闪光。机组人员在近七小时的月球观测期内共报告了6次撞击闪光，描述其为持续仅数毫秒、呈白色至蓝白色的细小光点。大部分观测事件发生在2026年4月6日的日食期间，当时月球处于太阳背光位置，只有阿尔忒弥斯二号的机组人员能观测到这一景象。NASA的科学家们对这些观测结果感到惊喜，因为此前普遍不认为机组人员会在本次任务中目击此类撞击。地面团队目前正将机组人员的观测结果与月球轨道卫星的数据进行比对，以研究撞击频率和撞击物大小。专家指出，这些发现凸显了在建立月球基地前需更密切监测月球流星通量的必要性，因为月球没有大气层可以烧毁小型来袭天体。

Is crossing your legs actually bad for you?

    Contrary to childhood health warnings, there is little evidence that crossing legs damages the back, wears out hips or knees, or causes varicose veins. The old belief that proper sitting reflects discipline often makes social rules mistaken for medical facts. Posture research finds no universal ideal sitting position or everyday posture that reliably harms health, and global physiotherapists’ views on best posture vary widely. The bigger issue than crossing legs is staying in any single posture for too long, leading to discomfort. The human back is strong and adaptable, so people should vary positions, move more and avoid overestimating their body’s fragility.

跷二郎腿真的对你有害吗？

    与童年听到的健康警告相反，目前几乎没有证据表明跷二郎腿会损伤背部、磨损髋膝或引发静脉曲张。旧时认为“正确坐姿体现自律”的观念常让社会规则被误当作医学事实。坐姿研究未发现普适的理想坐姿或会可靠损害健康的日常坐姿，且全球物理治疗师对最佳坐姿的看法差异极大。相较于跷二郎腿，更大的问题是长时间保持单一姿势导致不适。人体背部强壮且适应性强，因此人们应变换姿势、多活动，避免高估自身身体的脆弱性。
