  • 俄罗斯货机深夜降落古巴军事机场,引发美警惕


    一架通常用于运送军事装备的俄罗斯货机周日晚间降落在哈瓦那的一个军事机场,其飞行模式与捕获委内瑞拉总统尼古拉斯·马杜罗之前的飞行轨迹相呼应。

    根据公开飞行数据,这架由美国制裁的俄罗斯国家关联航空公司Aviacon Zitotrans运营的伊留申伊尔-76运输机,被追踪降落在圣安东尼奥-德洛斯巴尼奥斯机场,这是一个位于哈瓦那以南约30英里的古巴军事设施。

    飞行追踪记录显示,该飞机曾在俄罗斯的圣彼得堡和索契、非洲毛里塔尼亚以及多米尼加共和国停留。每次降落都需要得到东道国政府的批准,这为了解哪些国家仍在允许与俄罗斯军方有关的航空活动(尽管受到西方制裁)提供了窗口。

    2025年10月底,当华盛顿与加拉加斯之间的紧张局势升级时,这架飞机曾飞往委内瑞拉、尼加拉瓜和古巴。这一行动在美军采取军事行动并最终结束马杜罗统治之前,美国官员和分析师此后指出,这一系列事件是评估该地区类似俄罗斯航空活动的预警指标。

    现在,古巴总统米格尔·迪亚斯-卡内尔正面临来自唐纳德·特朗普总统的日益增大的压力,特朗普在近几周大幅加强了美国对哈瓦那的政策。

    周四,特朗普宣布与古巴有关的国家紧急状态,称古巴政府对美国国家安全和外交政策利益构成”异常和非凡的威胁”。政府还表示,将对未经美国授权向古巴出售或供应石油的任何国家实施惩罚。

    特朗普周日证实,美国正与古巴官员进行直接谈判。

    “古巴是一个失败的国家。长期以来都是如此,但现在它没有了委内瑞拉的支持,”特朗普在佛罗里达州海湖庄园对记者说。”所以我们正在与古巴人民、古巴最高层人士进行谈判,看看会发生什么。我认为我们会与古巴达成协议。”

    特朗普和国务卿马尔科·卢比奥都表示支持哈瓦那的政治变革,尽管政府尚未表明是否会通过军事行动实现这一目标。

    俄罗斯与古巴的军事联系多次引发华盛顿的担忧。尽管冷战后苏联在该岛的影响力逐渐减弱,但莫斯科在过去十年中稳步重建了与哈瓦那的国防和情报合作。美国官员警告称,俄罗斯在古巴的重新活动可能对美国本土构成安全风险。

    伊尔-76是一种重型运输机,可运载约50吨货物或多达200名人员。考虑到运营商的历史,这种能力引起了人们的关注。Aviacon Zitotrans因支持俄罗斯国防部门而受到美国、加拿大和乌克兰的制裁。

    美国财政部在2023年1月将该航空公司列入制裁名单时表示:”Aviacon Zitotrans曾向世界各地运送火箭、弹头和直升机零件等军事装备。”

    目前尚不清楚这架飞机在最近一次飞行中携带了什么货物。在委内瑞拉的早期行动中,俄罗斯国家媒体和一名俄罗斯议员表示,同一架飞机向加拉加斯运送了”铠甲-S1″短程和” Buk-M2E”中程防空系统。

    A Russian cargo plane typically used to transfer military equipment landed at a military airfield in Havana Sunday night, echoing flight patterns seen ahead of the capture of Nicolás Maduro in Venezuela.

    The U.S.-sanctioned Ilyushin Il-76, operated by Russian state-linked airline Aviacon Zitotrans, was tracked landing at San Antonio de los Baños Airfield, a Cuban military installation roughly 30 miles south of Havana, according to public flight data.

    Flight-tracking records show the aircraft stopped in St. Petersburg and Sochi in Russia; Mauritania, Africa; and the Dominican Republic. Each landing would have required approval from host governments, offering a window into which countries are continuing to permit Russian military-linked aviation activity despite Western sanctions.

    The same aircraft conducted flights to Venezuela, Nicaragua and Cuba in late October 2025, as tensions between Washington and Caracas escalated. That movement preceded U.S. military action in Venezuela that ultimately ended Maduro’s rule — a sequence U.S. officials and analysts have since pointed to as a warning indicator when evaluating similar Russian aviation activity in the region.

    Now, Cuban President Miguel Díaz-Canel finds himself under mounting pressure from President Donald Trump, who has sharply intensified U.S. policy toward Havana in recent weeks.

    On Thursday, Trump declared a national emergency related to Cuba, asserting that the Cuban government poses an “unusual and extraordinary threat” to U.S. national security and foreign policy interests. The administration also said it would impose penalties on any country that sells or supplies oil to Cuba without U.S. authorization.

    Trump confirmed Sunday that the U.S. is engaged in direct talks with Cuban officials.

    [TRUMP SAYS CUBA IS ‘READY TO FALL’ AFTER CAPTURE OF VENEZUELA’S MADURO]

    “Cuba is a failing nation. It has been for a long time, but now it doesn’t have Venezuela to prop it up,” Trump told reporters at Mar-a-Lago, Florida. “So we’re talking to the people from Cuba, the highest people in Cuba, to see what happens. I think we’re going to make a deal with Cuba.”

    Trump and Secretary of State Marco Rubio have both indicated support for political change in Havana, though the administration has not said whether it would pursue that objective through military action.

    Russian military ties to Cuba have repeatedly triggered concern in Washington. While the Soviet Union’s footprint on the island receded after the Cold War, Moscow has steadily rebuilt defense and intelligence cooperation with Havana over the past decade. U.S. officials have warned that renewed Russian activity in Cuba could pose security risks close to the U.S. mainland.

    The Il-76 is a heavy transport aircraft capable of carrying roughly 50 tons of cargo or up to 200 personnel, a capability that has drawn scrutiny given the operator’s history. Aviacon Zitotrans has been sanctioned by the United States, Canada and Ukraine for supporting Russia’s defense sector.

    “Aviacon Zitotrans has shipped military equipment such as rockets, warheads, and helicopter parts all over the world,” the U.S. Treasury Department said in January 2023, when it added the airline to its sanctions list.

    It remains unclear what cargo the aircraft carried on its most recent flight. During earlier operations in Venezuela, Russian state media and a Russian lawmaker said the same aircraft delivered Pantsir-S1 short-range and Buk-M2E medium-range air defense systems to Caracas.

  • 金银价格在暴涨后暴跌,原因何在?


    2026年2月2日 / 美国东部时间下午12:11 / 哥伦比亚广播公司新闻

    贵金属的光芒正在褪去。上周创下历史新高的贵金属价格,在周五出现大幅抛售之后,持续下滑。

    Pepperstone高级研究策略师迈克尔·布朗指出,上周金价突破每盎司5500美元,而在隔夜交易中已跌至每盎司4500美元以下。周五的跌幅是该贵金属自2013年以来最大单日跌幅。白银同样遭遇最严重单日亏损,暴跌超过31%。

    截至美国东部时间上午10:30,黄金和白银价格已反弹至4779美元和81美元。

    金属价格暴跌背后的原因是什么?

    过去一年,由于全球地缘政治不确定性加剧和政府举债问题日益严重,投资者纷纷涌入贵金属市场,美国及其他主要经济体的债务水平持续攀升。

    周五的抛售发生在特朗普总统宣布提名凯文·沃什(Kevin Warsh)接替杰罗姆·鲍威尔(Jerome Powell)担任美联储主席之后。尽管沃什在过去一年一直主张降息,但他通常被视为对通胀持”鹰派”立场。

    华尔街分析师表示,由于消费者价格仍高于美联储每年2%的目标,这可能使沃什倾向于不采取特朗普所要求的激进降息政策。黄金价格通常(尽管并非总是)随着利率上升而下跌,因为黄金本身不产生利息,导致投资者转向股票和其他风险资产以寻求更高回报。

    摩根大通分析师指出,贵金属价格的暴跌还受到美元反弹的推动。在沃什被提名为美联储主席之前,美元曾跌至四年来的最低水平。黄金和美元的价值通常呈反向走势。

    摩根大通全球大宗商品研究执行董事格雷戈里·谢勒在周一与客户的电话会议中表示:”我们受到美元反弹的催化,在一定程度上是由于沃什的提名,从这个角度看,这确实是触发快速、显著去风险化的导火索……并在周五导致价格大幅回落。”

    其他因素也助长了抛售。金融咨询公司deVere Group的首席执行官奈杰尔·格林表示,投资者过去一年大量借贷以利用黄金价格上涨。但一旦价格开始下滑,许多投资者面临不断上升的保证金要求——经纪公司为维持杠杆头寸设定的最低金额。

    格林在电子邮件中表示:”许多投资者选择或被迫卖出,这一过程无论基本面如何都会压低价格。”

    贵金属价格现在将走向何方?

    华尔街对黄金和白银价格的未来走势看法不一。

    格林表示:”复苏可能不会立即到来或戏剧性上演,但我们认为,一旦强制平仓阶段结束,市场机制有利于反弹而非持续自由落体。”

    摩根大通分析师也认为硬资产可能会复苏。该银行在一份研究报告中上调了黄金年末目标价至6300美元。

    但投资咨询公司牛津经济研究院(Oxford Economics)的首席经济学家尼尔·谢林(Neil Shearing)在一份研究报告中表示,他预计黄金年底价格将”远低于当前水平”。

    他补充道:”虽然一些市场参与者可能因对全球经济和政治背景的真正担忧而买入黄金,但我们认为市场热情和一定程度的错失恐惧(FOMO)正在使黄金泡沫膨胀。”

    Gold and silver prices are slumping after their meteoric rise. Here’s why.

    February 2, 2026 / 12:11 PM EST / CBS News

    The shine is coming off gold and silver. Prices for the precious metals, which last week soared to record highs, are extending their slide after a sharp selloff on Friday.

    Gold, which topped $5,500 last week, dipped below $4,500 per ounce in overnight trading. Friday’s decline amounted to the biggest one-day drop in the shiny metal’s price since 2013, noted Pepperstone senior research strategist Michael Brown. Silver also suffered its worst daily loss, tumbling more than 31%.

    As of 10:30 a.m. EDT, gold and silver had rebounded to $4,779 and $81.

    What’s behind the metals meltdown?

    Investors have poured into the metals in the last year amid concerns about mounting global geopolitical uncertainty and government borrowing, as debt levels across the U.S. and other major economies continue to rise.

    The sell-off on Friday came after President Trump announced Kevin Warsh as his nominee to succeed Jerome Powell as chair of the Federal Reserve. Although Warsh has over the last year argued in favor of lowering interest rates, he is generally viewed as “hawkish” on inflation.

    With consumer prices still running above the Fed’s annual 2% target, that could incline Warsh against the kind of aggressive rate-cutting that President Trump has demanded, according to Wall Street analysts. Gold prices often (though not always) fall as interest rates rise because holdings of the metal don’t pay interest, leading investors to rotate into stocks and other risk assets in search of higher returns.

    The plunge in precious metal prices was also fueled by a rebound in the dollar, which had fallen to its lowest level in four years before Warsh was nominated as Fed chair, according to JPMorgan analysts. The values of gold and the dollar typically move in opposite directions.

    “We get a catalyst of a rebound in the U.S. dollar, to some degree on the back of the nomination of Warsh, and from that perspective, that’s really the trigger that leads to very swift, significant de-risking… and the real sharp rollover into Friday,” Gregory Shearer, executive director of global commodities research at J.P. Morgan, in a call with clients on Monday.

    Other factors also fed into the sell-off. Investors had borrowed heavily capitalize on the run-up in gold over the last year. But once prices began to slide, many of those same investors faced rising margin requirements, the minimum amount set by brokerage firms to maintain their leveraged position, according to Nigel Green, CEO of financial consulting firm deVere Group.

    “Many chose, or were forced, to sell,” Green said in an email. “This process pushes prices lower regardless of fundamentals.”

    Where are precious metal prices headed now?

    On Wall Street, opinions are mixed on where gold and silver prices go from here.

    “The recovery may not be immediate or dramatic, but we believe the mechanics favor a bounce rather than continued freefall once the forced phase ends,” Green said.

    JPMorgan analysts also think the hard assets are likely to recover. In a research note, commodities analysts with the bank lifted their year-end target for gold to $6,300.

    But Neil Shearing, group chief economist at investment advisory firm Oxford Economics, said in a research note that he expects gold to end the year “well below current levels.”

    “While some market participants may be buying gold due to genuine concerns about the global economic and political backdrop, our sense is that market exuberance and a dose of FOMO are inflating a bubble in gold,” he added.

  • 金价大跌后中国黄金市场抄底与观望并存

    国际金价上周大跳水后,中国黄金消费市场出现抄底与观望并存的局面。中国多家银行机构提示理性投资,避免盲目追涨杀跌,并调高投资黄金门槛。

    被视为中国黄金消费热度风向标的北京菜百首饰商场,星期一(2月2日)涌入不少前来抄底的中国投资者。《联合早报》记者当天中午抵达商场四楼的投资金条柜台时,排队购金的人龙一度达上百人。

    一名77岁的北京居民告诉记者,他打算买100克金条。他表示并不担心金价短期内继续下跌,买金条主要是作为长期投资,为下一代建仓,并看好10年、20年后的回报,“肯定赔不了钱”。

    投资金条柜台屏幕投放“菜百投资基础金价”随着国际金价回落已连降三天,星期一中午报每克1030元(人民币,下同,188新元)左右,较上周四(1月29日)的高位回落约600元,意味着之前进场的部分投资者已被套牢。

    今年涨势如虹的国际金价,在1月29日一度突破每安士5500美元(6989新元)大关,却在隔天突然跳水,遭遇自1980年代以来最剧烈单日下跌,并跌破5000美元关口。截至星期一晚上9时,金价报每安士4790美元。

    市场普遍认为,金价此轮回落始于美国政府拟提名沃什(Kevin Warsh)出任美国联邦储备局主席。消息得到确认后导致美元走强,抑制以美元计价的贵金属吸引力。

    经济学人智库高级分析师徐天辰注意到,购买金饰并不划算,因为其中包含加工费,且回收价格通常被压低;相比之下,中国消费者更倾向于购买金条,反映出市场中存在较强的投机成分。

    他指出,市场普遍共识仍是金价长期向上,过去一周“跌出了一个很深的坑”,让不少人觉得是入场的好时机。

    中国经济学者盘和林研判,中国消费者购金热潮或将迅速降温,因为国内金价正进入调整期,趋势已出现逆转。他指出,中国消费者购金的主要动力就是金价上涨,如今“金价已经发生趋势性逆转,此时投资者的做多风险会比较高”。

    40岁的刘姓媒体从业者告诉本报,她已投资黄金四年,主要购买金条等实体黄金,恰好在1月29日减仓套现。眼见金价近期剧烈波动,她直言:“可能今年至少上半年,我个人不会再去碰黄金。”

    中国多家银行近期相继发布风险提示,并调高投资黄金门槛。例如,中国工商银行自1月29日起通过“工银金行家”微信公号多次提示贵金属市场价格波动风险,建议客户“在审慎评估自身风险承受能力的基础上,保持理性投资心态,避免盲目追涨杀跌”。

    中国建设银行上周五(1月30日)也在官网宣布,从星期一上午起将个人黄金积存业务的定期积存起点金额上调至1500元。

    《中国基金报》引述业内人士分析称,1月以来黄金市场震荡加剧,多家银行上调积存金业务门槛,一方面是响应监管对投资者适当性管理的要求,另一方面也是为保护投资者利益,防止短期内出现非理性追涨行为。

  • 美国国家航空航天局为阿尔忒弥斯二号月球火箭加注燃料,为超级碗周日发射铺平道路


    2026年2月2日 / 美国东部时间下午12:55 / 哥伦比亚广播公司新闻

    工程师周一开始为美国国家航空航天局(NASA)的阿尔忒弥斯二号月球火箭加注超过75万加仑的超冷推进剂,进行关键的倒计时”湿彩排”演练,以验证这枚巨型火箭是否无泄漏,并为最早于2月8日将四名宇航员送往绕月之旅做好准备。

    此次倒计时演练于周六晚上开始——由于佛罗里达州航天海岸的严寒天气推迟了两天——并在周一上午召开会议评估天气和团队准备情况后,发射主任查理·布莱克威尔-汤普森(Charlie Blackwell-Thompson)批准工程师开始远程控制的燃料加注操作。

    美国国家航空航天局的太空发射系统(SLS)火箭矗立在肯尼迪航天中心39B号发射台顶部。工程师周一早早开始工作,将超过75万加仑的超冷液态氧和液态氢燃料注入这枚32层高的火箭,作为倒计时彩排的一部分,为发射扫清障碍。NASA

    倒计时安排在东部时间晚上9点进行模拟发射。但工程师计划在此之后继续几个小时,以完成多个循环程序,确保团队能够应对实际倒计时中可能出现的任何问题和延误。

    根据对燃料加注测试数据的审查结果,阿尔忒弥斯二号任务指挥官里德·怀斯曼(Reid Wiseman)、维克多·格洛弗(Victor Glover)、克里斯蒂娜·科赫(Christina Koch)和杰里米·汉森(Jeremy Hansen)最早可能在2月8日晚上11:20——超级碗周日——获得发射许可,这是2月份发射窗口期仅剩的三天中的第一天。如果太空发射系统(SLS)在2月11日前未能升空,此次飞行将推迟至3月初。

    SLS是NASA计划用于将阿尔忒弥斯宇航员送入月球轨道的猎户座乘员舱的火箭,是世界上最强大的现役发射器。这枚332英尺高的火箭由两个捆绑式固体燃料助推器和四个主发动机提供动力,在发射时可产生880万磅的推力,主发动机燃烧液态氧和液态氢燃料。

    该火箭的首次任务是在2022年进行的无人绕月测试飞行,返回地球。在发射前的准备阶段,工程师遇到了各种问题,从燃料泄漏到发射台管道中意外的推进剂流动异常。发射因此被推迟了数月,工程师们努力解决这些问题。

    对于火箭的第二次发射,已实施了多项升级和改进,布莱克威尔-汤普森表示,她对此次燃料加注测试的顺利进行持乐观态度。

    “我们为什么认为会成功?这是我们吸取的教训,”她上周表示。

    “阿尔忒弥斯一号是一次测试飞行,在那次发射过程中我们学到了很多,”她说。”我们学到的关于如何为航天器加注燃料、如何加注液氧(LOX)、如何加注液氢的经验,都已融入到我们计划为阿尔忒弥斯二号火箭进行燃料加注的流程中。”

    燃料加注操作预计在下午4:30左右完成,核心级和二级燃料箱将被注满并进入”稳定补充”模式。在实际的月球发射倒计时中,燃料加注的完成将为宇航员前往发射台并系入他们的猎户座飞船铺平道路。

    但在此次燃料加注测试中无人登船。怀斯曼和他的船员们仍在休斯顿约翰逊航天中心接受飞行前的医学隔离,预计在完成彩排数据评估后才会在本周晚些时候飞往佛罗里达。

    NASA fuels Artemis II moon rocket in test to clear the way for Super Bowl Sunday launch

    February 2, 2026 / 12:55 PM EST / CBS News

    Engineers began loading NASA’s Artemis II moon rocket with more than 750,000 gallons of supercold propellants Monday in a critical countdown “wet dress” rehearsal to verify the giant rocket is leak-free and ready to send four astronauts on a trip around the moon as early as Feb. 8.

    The practice countdown began Saturday evening — two days late because of frigid weather along Florida’s Space Coast — and after a meeting Monday morning to assess the weather and the team’s readiness to proceed, Launch Director Charlie Blackwell-Thompson cleared engineers to begin the remotely-controlled fueling operation.

    NASA’s Space Launch System rocket stands atop pad 39B at the Kennedy Space Center. Engineers began work early Monday to pump more than 750,000 gallons of supercold liquid oxygen and hydrogen fuel into the 32-story-tall rocket in a dress rehearsal countdown to clear the way for launch. NASA

    The countdown was timed for a simulated launch at 9 p.m. EST. But engineers planned to continue several hours past that to run through several recycle procedures intended to make sure the team is ready to handle any problems and delays that might crop up during a real countdown.

    Depending on the results of a review of the fueling test data, Artemis II commander Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen could be cleared for launch as early as 11:20 p.m. on Feb. 8 — Super Bowl Sunday — the first of just three days left in the February launch period. If the Space Launch System (SLS) isn’t off the ground by Feb. 11, the flight will slip to early March.

    The SLS, the rocket NASA plans to use to send Artemis astronauts to the moon aboard Orion crew capsules, is the most powerful operational launcher in the world. It is a towering 332-foot-tall rocket powered by two strap-on solid fuel boosters and four main engines burning liquid oxygen and hydrogen fuel that generate 8.8 million pounds of thrust at liftoff.

    The rocket’s first and so far only mission came in 2022 when it was launched on an unpiloted test flight around the moon and back. In the campaign leading up to launch, engineers ran into a variety of problems ranging from fuel leaks to unexpected propellant flow behavior in the launch pad’s plumbing. Launch was delayed for months while engineers worked to resolve the problems.

    For the rocket’s second launch, multiple upgrades and improvements have been implemented, and Blackwell-Thompson said she was optimistic the fueling test would go well.

    “Why do we think that we’ll be successful? It’s the lessons that we learned,” she said last week.

    “Artemis I was the test flight, and we learned a lot during that campaign, getting to launch,” she said. “And the things that we learned relative to how to go load this vehicle, how to load LOX (liquid oxygen), how to load hydrogen, have all been rolled into the way in which we intend to load the Artemis II vehicle.”

    The fuel loading operation was expected to be complete by around 4:30 p.m. with the tanks in the core and second stages topped off and in “stable replenish” mode. During an actual moon launch countdown, the completion of fueling would set the stage for the astronauts to head for the pad to strap into their Orion capsule.

    But no one would be boarding for the fueling test. Wiseman and his crewmates remained in pre-flight medical quarantine at the Johnson Space Center in Houston and were not expected to fly to Florida until later this week, after the dress rehearsal data is assessed.

  • 科学家新发现:生命所需原料或源自宇宙


    发布时间:2026年2月2日 23:26 / 来源:联合早报

    科学家近日在星际空间中发现了迄今为止最大的含硫有机分子,这一发现为理解生命化学起源提供了新的线索。

    研究人员认为,这种分子的发现,有助于补上科学界长期困惑的一环:生命所需的复杂分子,可能并非凭空出现,而是由宇宙中的简单化学物质逐渐演化而来。

    美国有线电视新闻网(CNN)报道,硫(Sulfur)是宇宙中含量排名前列的元素,也是地球生命不可或缺的组成部分,广泛存在于氨基酸、蛋白质和酶之中。尽管科学家此前曾在彗星和陨石中发现含硫分子,但在恒星之间的星际空间中,体积较大的含硫分子长期难以探测,相关现象一直令研究人员感到困惑。

    此次发现的分子由13个原子组成,同时含有硫、碳和氢,是目前在太空中确认的最大含硫分子。

    研究人员指出,发现更复杂的分子至关重要,因为它们有助于弥合太空中简单分子与可能孕育生命的复杂化学结构之间的差距,也支持了“生命所需原料可能源自宇宙”的假说。

    该分子是在银河系中心附近、距离地球约2.7万光年的一个分子云中被探测到的。

    分子云由低温、高密度的尘埃和气体组成,是恒星和行星系统形成的“摇篮”。科学家认为,这些区域中形成的化学物质,或在行星诞生过程中被保留下来,并通过彗星或陨石撞击,最终被带到像地球这样的行星上。

    为确认该分子的存在,研究人员先在实验室中人工合成该分子,并获取其精确的“无线电指纹”,再与射电望远镜观测数据进行比对,从而锁定其信号来源。

    研究团队指出,这一成果意味着未来有望在太空中发现更多、甚至更复杂的含硫分子。

    多名未参与研究的学者认为,这项发现展示了宇宙化学的高度复杂性,也增强了生命关键物质在宇宙中普遍存在的可能性。但研究人员也强调,有关发现并不等同于发现生命本身,而只是帮助科学界更好理解生命从无机化学逐步演化而来的路径。

  • 教育专家警告:曼达尼计划或削弱纽约市天才儿童项目,损害低收入学生


    社会主义市长抨击天才与资优项目,认为其加剧不平等

    社会主义纽约市市长佐伦·曼达尼已概述计划缩减该市“天才与资优项目”(Gifted and Talented),引发部分教育专家警告称,此举可能剥夺高成就学生(尤其是来自低收入家庭的学生)的关键学术机会。

    近期媒体报道显示,2025年1月就职的曼达尼计划终止针对幼儿园学生的天才与资优项目,并将入学延迟至三年级。批评者认为,这一举措将严重削弱美国最大学区的加速学习选项。

    该计划遭到“捍卫教育”(Defending Education)——一个全国性教育监督组织的强烈反对。该组织此前曾在一场持续数年的法律斗争中胜诉,成功保住了纽约州的天才项目,当时争议焦点是招生制度存在歧视性影响,加剧了教育领域的种族不平等。

    “上诉法院正确裁定,司法机构不应制定教育政策,”“捍卫教育”副总裁兼法律研究员莎拉·帕沙尔·佩里在接受《福克斯新闻数字版》采访时表示,并补充称该项目符合州教育法和平等保护条款。

    但佩里警告称,曼达尼的政策议程可能会推翻法院裁定的内容。

    “正如我们所料,新晋民主社会主义市长佐伦·曼达尼——其本人出身于昂贵私立学校——承诺关闭天才与资优项目,尽管该项目已帮助无数背景普通的学生充分发挥学术潜力,”佩里对《福克斯新闻数字版》表示。

    “剥夺孩子们急需的高级学习机会不仅鲁莽,对一个出生于富裕家庭、就读昂贵私立学校的人而言更是极度虚伪。显然,曼达尼认为只有特权阶层才应享有各类教育机会。”

    曼达尼辩称,早期天才测试导致学校系统内的不平等,而批评者反驳称,取消选拔性项目对改善困难学生的学业成果作用甚微,反而会主动损害成绩优异者。

    “捍卫教育”K-12项目战略举措高级总监保罗·伦科呼应了佩里的担忧,强调此类改革对工人阶级家庭的影响。

    “代表那些只想为子女争取最优教育的家长,‘捍卫教育’多年来在法庭上奋力抗争,以保住纽约市的天才与资优项目,抵制试图通过法院将种族问题注入学校系统各个方面的企图,”伦科表示。

    “如果曼达尼市长推进取消这些加速学习机会的计划,这些努力可能会功亏一篑,”他警告道。“学生——尤其是从低收入家庭受益于纽约天才与资优项目的学生——理应获得卓越学术机会,而非一种‘一刀切’的方案,这种方案可能会削弱所有学生的学习效果。”

    曼达尼办公室驳斥了“捍卫教育”的指控,称政府反对对5岁儿童进行天才与资优项目测试,但并未全面取消所有年级的高级学习机会

    其办公室表示,重点反而应放在重塑公立学校系统,为所有学生提供“严格”教学,而非在幼年阶段就对孩子进行分流。

    曼达尼在市长竞选期间及其对手、以及《华盛顿邮报》编辑委员会(2025年10月)均对其改变项目的计划提出激烈批评。

    “谁能想到,作为下任纽约市长热门候选人的佐伦·曼达尼(民主党),会以‘公平’之名宣布计划逐步淘汰该市天才学生的早期小学项目,从而引发轩然大波?聪明孩子的父母希望获得满足其需求的教育,”《华盛顿邮报》写道。“令人震惊。”

    Education experts warn Mamdani plan could gut NYC gifted programs, hurt low-income students

    Socialist mayor takes aim at Gifted and Talented program, believing it contributes to inequality

    By Andrew Mark Miller

    Published February 2, 2026 11:00am EST

    Socialist New York City Mayor Zohran Mamdani has outlined plans to scale back the city’s Gifted and Talented program, prompting some education experts to warn that doing so could deprive high-achieving students, particularly those from low-income families, of critical academic opportunities.

    Recent media reports indicate that Mamdani, who took office in January,intends to end the city’s Gifted and Talented program for kindergarten students and delay entry until third grade, a move critics argue would amount to a major weakening of accelerated learning options in the nation’s largest school district.

    The plan is drawing sharp criticism from Defending Education, a national education watchdog group that previously fought, and won, a years-long legal battle to preserve New York’s gifted programs after it was argued that the admissions system had discriminatory effects and reinforced racial inequities in education.

    “The Court of Appeals rightly concluded that the role of the judiciary is not to make education policy,” Sarah Parshall Perry, vice president and legal fellow at Defending Education, told Fox News Digital, adding that the program complied with state education law and equal protection requirements.

    But Perry warned that Mamdani’s policy agenda could undo what the courts upheld.

    “As we suspected he might, newly minted democratic socialist mayor Zohran Mamdani — himself, a product of expensive private schools — has pledged to shut down the gifted and talented program, despite the fact that it has helped countless students from humble backgrounds achieve their full academic potential,” Perry told Fox News Digital.

    “Depriving kids of much-needed advanced learning opportunities is not only foolhardy, but it’s also the height of hypocrisy coming from someone who was born into affluence and attended costly private schools. Apparently, Mamdani believes only the privileged should have access to various educational opportunities.”

    Mamdani has argued that early gifted testing contributes to inequities in the school system, though critics counter that dismantling selective programs does little to improve outcomes for struggling students while actively harming high performers.

    Paul Runko, senior director of strategic initiatives for K-12 programs at Defending Education, echoed Perry’s concerns, emphasizing the impact such changes could have on working-class families.

    “On behalf of parents who simply want the best possible education for their children, Defending Education spent years in court fighting to preserve New York City’s gifted and talented programs against efforts to use the courts to inject race into every aspect of the school system,” Runko said.

    “Those efforts may succeed if Mayor Zohran Mamdani moves forward with eliminating these accelerated learning opportunities,” he warned. “Students, particularly those from lower-income families who benefit from NYC’s gifted and talented programs, deserve opportunities for academic excellence, not a one-size-fits-all approach that could weaken learning for all students.”

    Mamdani’s office pushed back on Defending Education’s characterization, telling Fox News Digital that the administration opposes testing five-year-olds for gifted and talented programs but is not eliminating advanced learning opportunities across all grade levels.

    Mamdani’s office said the focus is instead on reshaping the public school system to provide “rigorous” instruction for all students, rather than separating children at an early age.

    Mamdani faced heated criticism from his opponents in the mayoral race regarding his plans to change the program, as well as from the Washington Post editorial board in October.

    “Who could have guessed that Zohran Mamdani (D), the leading candidate to become the next New York mayor, would provoke a firestorm by announcing this week that he intends to phase out the city’s early elementary school programs for gifted students in the name of equity? Parents of bright children want access to schooling that meets their needs?” The Post wrote. “Shocking.”
