Economy
Global bond markets came under intense pressure on May 15–18 as yields on long-dated government debt surged across major economies. The U.S. 10-year Treasury yield broke above 4.5 percent, Japan's 30-year bond hit an all-time record, and UK gilts climbed to levels not seen since 1998. Analysts attributed the synchronized sell-off to persistent inflation fears driven by elevated oil prices — with Brent crude topping $111 per barrel — amid the unresolved U.S.-Iran conflict and the ongoing Strait of Hormuz blockade. The spike in borrowing costs sent equities tumbling: the Dow Jones fell more than 2 percent, the Nikkei 225 dropped 0.47 percent, and Boeing shares slid over 4 percent after the company reported earnings that missed expectations. Gold prices recovered to $4,535.73 per ounce after touching a 1.5-month low, while the U.S. dollar weakened as investors sought safety in commodities.
全球债券市场在5月15日至18日期间承受巨大抛压，各主要经济体长期国债收益率大幅攀升。美国10年期国债收益率突破4.5%，日本30年期国债创下历史新高，英国国债收益率升至1998年以来最高水平。分析师将此轮同步抛售归因于持续的通胀担忧——布伦特原油价格突破每桶111美元——而美伊冲突及霍尔木兹海峡封锁问题悬而未决。借贷成本飙升引发股市大跌：道琼斯指数下跌逾2%，日经225指数下跌0.47%，波音公司因业绩不及预期股价重挫逾4%。黄金价格在触及一个半月低点后反弹至每盎司4,535.73美元，美元则因投资者转向大宗商品避险而走弱。
Geopolitics
Russian President Vladimir Putin is set to arrive in Beijing on May 19 for a two-day state visit at the invitation of Chinese President Xi Jinping, marking his 25th trip to China. The visit comes just days after U.S. President Trump concluded his own state visit to Beijing on May 13, during which a preliminary trade deal was announced including China's agreement to purchase 200 Boeing aircraft. Chinese foreign ministry spokesperson Guo Jiakun said the two sides would "take this visit as an opportunity to continue to promote the development of China-Russia relations to a higher level, which will inject greater stability and positive energy into the world." Meanwhile, U.S.-Iran peace talks remain stalled: Iran's semi-official Mehr news agency reported on May 18 that Washington has put forward "maximalist" conditions, demanding Iran transfer its entire 400 kg enriched uranium stockpile to the United States while rejecting any reparations or frozen-asset releases. Separately, a drone strike triggered a fire at an external power generator near the Barakah Nuclear Power Plant in Abu Dhabi on May 17, though no radiological release occurred.
俄罗斯总统普京应邀将于5月19日抵达北京，开始为期两天的国事访问，这将是普京第25次访华。此次访问恰逢美国总统特朗普5月13日结束对北京的国事访问不久，其间双方宣布达成初步贸易协议，包括中方同意购买200架波音飞机。中国外交部发言人郭嘉昆表示，双方将"以此访为契机，继续推动中俄关系向更高水平发展，为世界注入更多稳定性和正能量"。与此同时，美伊和谈陷入僵局：伊朗半官方通讯社梅赫尔5月18日报道，华盛顿提出了"最大化"条件，要求伊朗将其全部400公斤浓缩铀库存移交美国，同时拒绝任何赔偿或解冻资产。此外，5月17日一架无人机袭击了阿布扎比巴拉卡核电站附近的外部发电机并引发火灾，但未发生放射性泄漏。
Science & Technology
New research published in Physical Review Letters on May 18 suggests that neutrinos may play a far more decisive role in stellar explosions than previously understood. The study reveals a hidden "supernova switch" mechanism in which neutrino interactions within a collapsing star's core can determine whether the star successfully explodes or quietly collapses into a black hole. The findings could reshape models of core-collapse supernovae, which are among the most energetic events in the universe and are responsible for seeding the cosmos with heavy elements essential for planet formation and life. The discovery adds to a growing body of evidence that these ghostly, nearly massless particles — trillions of which pass through every square centimeter of the Earth each second — exert far greater influence on the fate of massive stars than their elusive nature would suggest.
5月18日发表于《物理评论快报》的一项新研究表明，中微子在恒星爆炸过程中所起的决定性作用可能远超此前认知。该研究揭示了一种隐藏的"超新星开关"机制：在坍缩恒星核心内部，中微子之间的相互作用能够决定恒星是成功爆炸还是悄然坍缩为黑洞。这一发现可能重塑核心坍缩超新星的模型——这类超新星是宇宙中能量最高的事件之一，负责将形成行星和生命所必需的重元素播撒到宇宙中。越来越多的证据表明，这些幽灵般的、几乎无质量的粒子——每秒有数万亿个穿过地球的每一平方厘米——对大质量恒星命运的影响远比其难以捉摸的特性所暗示的要大得多。
Healthcare
The World Health Organization on May 17 declared the Ebola outbreak in the Democratic Republic of the Congo and Uganda a Public Health Emergency of International Concern (PHEIC) — the highest level of global health alarm. The outbreak, caused by the Bundibugyo virus species, has so far produced 336 suspected cases and 87 suspected deaths in DRC's Ituri Province, with eight confirmed cases plus one in Kinshasa. Two confirmed cases imported from DRC were reported in Kampala, Uganda, with no apparent epidemiological link between them, raising fears of wider spread. By May 18, the virus had reached Goma, a city of over one million people near the Rwandan border, prompting Rwanda to close key border crossings. At least four healthcare workers in the affected areas have died, heightening concerns about nosocomial transmission. The Africa CDC has activated its Incident Management Support Team to coordinate response across DRC, Uganda, and South Sudan.
世界卫生组织于5月17日宣布刚果民主共和国和乌干达的埃博拉疫情构成"国际关注的突发公共卫生事件"（PHEIC），这是全球卫生领域的最高级别警报。此次疫情由邦迪布约型埃博拉病毒引起，迄今已在刚果（金）伊图里省造成336例疑似病例和87例疑似死亡，另有8例确诊病例，金沙萨也出现1例。乌干达首都坎帕拉报告了两例从刚果（金）输入的确诊病例，且两者之间无明显流行病学关联，引发疫情进一步扩散的担忧。截至5月18日，病毒已蔓延至与卢旺达边境相邻、人口超过百万的戈马市，促使卢旺达关闭了主要边境口岸。疫区至少有四名医务工作者因埃博拉死亡，院内感染风险令人担忧。非洲疾控中心已启动事件管理支持团队，协调刚果（金）、乌干达和南苏丹三国的防疫工作。

A 5.2-magnitude earthquake struck Liuzhou, a city in south China's Guangxi Zhuang autonomous region, at 0:21 a.m. on May 18, at a shallow depth of 8 kilometers. The quake hit Liunan District, leaving two people dead, one missing, and four hospitalized. Rescue teams recovered the final trapped person from the Sunay Village community at around 11:10 a.m., with stable vital signs. Guangxi's regional earthquake relief headquarters launched a Level-III emergency response, while the State Council's earthquake relief office and the Ministry of Emergency Management activated a Level-IV response and dispatched a work team to the area. A total of 51 fire and rescue vehicles and 315 personnel were deployed to the affected zone. Local authorities were ordered to verify casualties and damage, organize search and rescue, evacuate residents, and monitor for aftershocks.
5月18日凌晨0时21分，中国南方广西壮族自治区柳州市柳南区发生5.2级地震，震源深度仅8公里。地震造成2人死亡、1人失联、4人住院治疗。救援队伍于上午11时10分许在太阳村社区搜救出最后一名被困人员，生命体征平稳。广西壮族自治区地震救灾指挥部于凌晨2时启动三级应急响应，国务院抗震救灾指挥部办公室和应急管理部启动四级应急响应并派出工作组赶赴灾区。共调集51辆消防救援车辆和315名救援人员投入救灾。当地政府被要求尽快核实伤亡和损失情况，组织搜救，疏散受灾居民，并监测余震。
