The Federal Aviation Administration (FAA) requires that, in the event of an emergency, all airplane passengers must be able to evacuate any aircraft within a 90-second window. But is that a realistic requirement, particularly given the increasing number of elderly passengers who might need more time and assistance? According to a new paper published in the journal AIP Advances, it is not. Various simulated scenarios showed evacuation times significantly higher than the 90-second requirement. This isn't the first time scientists have puzzled over this kind of optimization problem. Back in 2011 , Jason Steffen, now a physicist at the University of Nevada, Las Vegas, became intrigued by the question of the most efficient boarding method; he applied the same optimization routine used to solve the famous traveling salesman problem to airline boarding strategies. Steffen fully expected that boarding from the back to the front would be the most efficient strategy and was surprised when his results showed that strategy was actually the least efficient. The most efficient, aka the “Steffen method,” has the passengers board in a series of waves. Field tests bore out the results , showing that Steffen’s method was almost twice as fast as boarding back-to-front or rotating blocks of rows and 20–30 percent faster than random boarding. The key is parallelism: The ideal scenario is having more than one person sitting down at the same time. Read full article Comments

Stocks on Tuesday again attempted to claw back some of their losses from the U.S.-Iran war. Some chart analysts think there's more downside ahead, however. Equities got a jolt after a report said President Donald Trump was open to ending U.S. involvement in the conflict in the Middle East — even if the Strait of Hormuz wasn't reopened. Still, Wolfe Research said that markets will be biased to the downside unless the conflict ends and the Strait of Hormuz reopens or there is a major sell-off event that marks a bottom. "While the price action over the past several days has suggested investors are slowly edging closer to capitulation, as the VIX index once again spiked above 30, our sense is that stocks are likely to slowly grind lower in the face of headline risks to either direction," wrote strategist Chris Senyek.

Welcome to The Brink . I’m Edward Clark , a reporter in London, where I’m following how loans to AD Education ran foul of the French budget crunch. We also have news on trouble at two Fortress Investment-backed companies, Brightline Trains Florida and discount retailer Poundstretcher. Follow this link to subscribe . Send us feedback and tips at debtnews@bloomberg.net . Hard Lesson AD Education has become a cautionary tale for political risks that may be hiding in plain sight. The French company, which offers private higher education , is nevertheless exposed to public policies — specifically a pullback in once-generous funding for apprenticeships. These placements account for one third of AD Education’s revenue, according to Moody’s Ratings . AD Education’s loans have been left reeling by the policy shift, enacted months after the private-equity owned firm raised €700 million from investors in November 2024. The debt now trades at a distressed price of 67 cents on the euro, compared with close to par at issue. “Policy risk in education is no longer hypothetical,” said Alex Edmondson , head of private equity at law firm Macfarlanes . “It is already reshaping the deal landscape significantly, and investors need to be aware of these risks when making decisions.” Emmanuel Macron ’s cash-strapped government introduced changes last year to apprenticeship funding that shift more of the cost and administrative burdens onto employers. Management at AD Education and private equity owner Ardian see mainly a short-term impact. They contend that the new policies will force smaller competitors out of business, driving more students to its courses, people familiar with the matter told Bloomberg News on condition of anonymity. But the company’s concentration on creative courses may turn out to be another negative, given diminished employment prospects and disruption from artificial intelligence. Moody’s downgraded the company’s debt one level to B3 this month, citing regulatory cha...

格隆汇3月31日｜路透调查显示，由于美以对伊朗战争实际上关闭了霍尔木兹海峡并迫使出口削减，欧佩克石油产量在3月大幅下降，降至2020年6月新冠疫情高峰以来最低水平。调查显示，欧佩克成员国3月原油产量环比减少730万桶/日至2157万桶/日，主要受科威特、伊拉克、沙特阿拉伯和阿联酋减产所推动。调查还显示，当月仅有委内瑞拉和尼日利亚两个成员国实现增产。路透调查基于LSEG的流量数据、Kpler等航运追踪机构的数据，以及来自石油公司及咨询机构的消息来源。

Merlin could disappear in worst-case scenario, with British isles facing ecological ‘point of no return’ The merlin, Britain’s smallest bird of prey, is one of more than 200 species that will become extinct in the UK if action is not taken to curb emissions and unsustainable land use, a study has claimed. According to the UK Centre for Ecology & Hydrology (UKCEH), there is a 20-year window in which decisions on climate and land use will determine the fate of dozens of Britain’s native species.

Anthropic appears to have accidentally revealed the inner workings of one of its most popular and lucrative AI products, the agentic AI harness Claude Code, to the public. A 59.8 MB JavaScript source map file ( .map ), intended for internal debugging, was inadvertently included in version 2.1.88 of the @anthropic-ai/claude-code package on the public npm registry pushed live earlier this morning. By 4:23 am ET, Chaofan Shou (@Fried_rice) , an intern at Solayer Labs, broadcasted the discovery on X (formerly Twitter). The post, which included a direct download link to a hosted archive, acted as a digital flare. Within hours, the ~512,000-line TypeScript codebase was mirrored across GitHub and analyzed by thousands of developers. For Anthropic, a company currently riding a meteoric rise with a reported $19 billion annualized revenue run-rate as of March 2026, the leak is more than a security lapse; it is a strategic hemorrhage of intellectual property.The timing is particularly critical given the commercial velocity of the product. Market data indicates that Claude Code alone has achieved an annualized recurring revenue (ARR) of $2.5 billion, a figure that has more than doubled since the beginning of the year. With enterprise adoption accounting for 80% of its revenue, the leak provides competitors—from established giants to nimble rivals like Cursor—a literal blueprint for how to build a high-agency, reliable, and commercially viable AI agent. We've reached out to Anthropic for an official statement on the leak and will update when we hear back. The anatomy of agentic memory The most significant takeaway for competitors lies in how Anthropic solved "context entropy"—the tendency for AI agents to become confused or hallucinatory as long-running sessions grow in complexity. The leaked source reveals a sophisticated, three-layer memory architecture that moves away from traditional "store-everything" retrieval. As analyzed by developers like @himanshustwts , the architectu...

Razer has announced its first keyboard with a split and curved ergonomic layout. The new Pro Type Ergo is available starting today , which at $189.99 is slightly more expensive than the more traditional $159.99 Pro Type Ultra that launched in 2021. Like its predecessor, Razer's new Pro Type Ergo is being positioned as a productivity tool instead of a gaming accessory, but still includes the company's signature colorful LED lighting broken up into 19 zones that can be customized or disabled. The Pro Type Ergo features ultra-low-profile, laser-etched ABS keys with a fingertip-shaped design and sound-dampening layers beneath, so you're not dist … Read the full story at The Verge.

The curriculum at creative institutions is evolving to handle gen AI tools, and a lot of people aren’t happy about it. | Image by Cath Virginia / The Verge When my baby brother, a 3D modelling and animation student, talks to me about his projects and studies, the pride I usually feel is becoming increasingly tainted by a growing sense of dread. As a creative professional and former design student myself, I understand all too well how fierce the competition for postgraduate jobs will be, but his future is being threatened by something that barely even existed during my own time in higher education: generative AI. College students are feeling that fear as well. Earlier this year, in a small protest at CalArts, posters that requested the help of AI artists for a thesis were reportedly altered wit … Read the full story at The Verge.

美光 科技股价周一大跌10%，此次抛售很大程度上是由 谷歌 发布的新型内存压缩算法引发的。 该算法名为TurboQuant，据称可在零精度损失的情况下，最多能将内存使用量减少至六分之一，同时提供高达八倍的性能提升。 这一消息令投资者感到恐慌，因为内存需求减少至六分之一，理论上意味着人工智能应用所需的内存芯片数量可减少约83%。这对美光近期的增长故事构成了直接威胁，其增长此前一直由人工智能驱动的高带宽内存和NAND芯片需求激增所支撑。 对人工智能内存需求可持续性的担忧，加剧了投资者对美光激进资本支出计划（预计将超过250亿美元）的已有顾虑。在谷歌消息传出加速下跌之前，该股自3月18日发布财报以来已呈下跌趋势。 责任编辑：张俊 SF065

LDL-C过高导致全球慢病死亡风险激增6.4倍，堪称“最隐匿的生命威胁”。 3月31日，默沙东的一项最新临床数据显示，该公司正在开发的新型口服降脂药物在一项后期头对头临床试验中，达到了显著降低低密度脂蛋白胆固醇（LDL-C）的主要目标，能显著降低“坏胆固醇”。 低密度脂蛋白胆固醇也被称为“坏胆固醇”。LDL-C的升高会引发高胆固酮血症，这种疾病通常会进一步导致动脉斑块形成。 今年早些时候，《新英格兰医学杂志》（NEJM）数据显示，LDL-C过高导致全球慢病死亡风险激增6.4倍，堪称“最隐匿的生命威胁”。 研究进一步揭露，LDL-C每上升1mmol/L，动脉壁斑块沉积速度将加快3-4倍，直接推动动脉粥样硬化进程，导致心肌梗死等冠心病风险骤增20%-30%。不仅如此，脑梗、外周动脉疾病、慢性肾病等常见慢病，背后也常见“坏胆固醇”失控。 长期以来，他汀类药物一直是降脂的常用药物，但它也有多种副作用，有相当一部分患者他汀不耐受。为此，近年来各大制药厂商的多种口服非他汀疗法正在开发中。 默沙东的这款在研非他汀类胆固醇药物enlicitide decanoate通过阻断一种在调节胆固醇水平中起关键作用的蛋白质PCSK9 （前蛋白转化酶枯草杆菌蛋白酶9）起作用，PCSK9也是近年来降脂药研发的热门靶点。 最新临床研究将enlicitide与现有的非他汀类口服降胆固醇药物贝派地酸（bempedoic acid）以及依折麦布（ezetimibe）进行头对头比较，发现在已经有他汀治疗背景的患者中，enlicitide可将LDL-C水平较基线水平降低多达64.6%；并且可将LDL-C水平较贝派地酸降低多达56.7%，较依折麦布降低36%。 加拿大丰业银行（Scotiabank）分析师预计，这种药物可能是默沙东最可能被低估的管线资产之一，并预计该药物上市后的峰值销售潜力可高达数百亿美元。 目前默沙东的这款药物已经获得了美国食品药品监督管理局的优先审评资格，丰业银行分析师预计，该药物最早可能在今年年内获批。 第一财经记者注意到，默沙东的这款在研药物在中国也已经在三期临床，用于动脉粥样硬化及高胆固醇血症适应症。 目前正在开发的类似疗法的制药巨头还包括阿斯利康。根据去年阿斯利康公布的一项中期试验数据，该公司正在研发的一种PCSK9口服降脂药可将“坏胆固醇”水平降低近51%。 阿斯利康还称，这款在...

在行业下行期，合作开发是房企获取土地和分散风险的重要方式，但项目利润需在股东之间分配，上市公司实际可确认的归母收益相应下降 【财新网】 在收入基本同比持平的情况下，越秀地产（00123.HK）2025年的盈利表现出现明显分化：总体利润同比增长，但归属于上市公司股东的收益却大幅下滑。 3月31日，越秀地产披露2025年业绩。该公司录得营收864.6亿元，同比微增0.1%；年内盈利17.78亿元，同比增长21.4%；归母净利润仅为0.55亿元，同比下降94.7%；核心净利润约2.6亿元，同比下降83.5%。 业绩报告显示，2025年越秀地产的收益分配结构发生变化，非控股权益达到17.23亿元，占年内利润总额的97%；归属于上市公司股东的部分仅占3%。可供比较的是，2024年越秀地产盈利14.65亿元，其中归属于上市公司股东的利润为10.40亿元，非控股权益为4.25亿元，占比分别为71%和29%。
