沙特阿拉伯媒体星期五（5月1日）引述美国一名官员的话报道说，美国海军“福特号”航空母舰在参与对伊朗的军事行动后已离开中东。

中东地区目前只剩下两艘美国大型军舰。

3月12日，福特号航母船尾洗衣房发生火灾，造成三名水兵受伤，另有200多名水兵因吸入浓烟接受治疗。福特号随后不得不撤离中东战区，先后到希腊和克罗地亚港口进行维修和维护。

美国官员4月17日向媒体披露，福特号在两艘驱逐舰护卫下离开地中海东部并穿越苏伊士运河，在红海海域执行任务。

国大研发新疗法 把益生菌变成“药”对抗肝性脑病

把益生菌变成“药”来用，新加坡国立大学研究团队研发出一种新疗法，有望更有效对抗肝衰竭引发的脑部问题，效果也优于现有常用抗生素治疗。

当肝脏出问题时，本应从血液中过滤掉的毒素如氨，会在体内越积越多，甚至跑进大脑，引发“肝性脑病”（hepatic encephalopathy）。病人可能变得焦虑、记忆力下降，严重时甚至昏迷。

领导这项研究的国大杨潞龄医学院国大合成生物学创新研究项目主任张旭教授受访时说，肝性脑病是肝硬化最常见，也最棘手的并发症之一。国际数据显示，每三到四名肝硬化患者中，就有一人会出现这种情况。

他说，在本地，慢性乙型肝炎、脂肪肝，以及长期饮酒，都是导致肝硬化的主要原因。随着人口老龄化，这类病例预计会增加，患者也更容易反复发作，不仅影响日常生活，也更常需要住院治疗。

目前的两种主要疗法，是泻药“乳果糖”（lactulose）和抗生素“利福昔明”（rifaximin），它们主要通过减少肠道内氨的产生来缓解症状。不过，这两种方法都无法从根本上调整体内失衡的代谢状态，因此病情容易反复；其中，利福昔明还可能破坏肠道原本的菌群。

改造益生菌 变成两种可“分工合作”菌株

为此，国大研究团队选用一种常见的益生菌——植物乳杆菌WCFS1（Lactobacillus plantarum WCFS1），加以改造，变成两种可以“分工合作”的菌株。

其中一种菌株，负责“吸走”肠道中过量的氨，并把它转化为人体需要的营养物质；另一种则在氨还没形成前，就把它的来源分解掉，从源头减少毒素产生。

实验结果显示，这两种菌株一起使用后，体内氨含量最多可降至原来的十分之一，脑部的氨水平也降回接近健康状态。同时，患者类似焦虑的表现和认知能力，都有明显改善。

研究团队指出，这种做法不只是“清毒”，还同时补充营养、调节体内状态，等于从多个方面一起处理问题，弥补现有疗法只有单一作用的不足。

国大合成生物学创新研究项目高级研究员阿加瓦尔博士（Nikhil Aggarwal）说，这种疗法未来有望通过口服方式使用，成为肝病患者日常护理的一部分，从而减少复发、稳定认知情况，并降低住院率。

张旭也指出，这类经过改造的细菌可以根据需要“分工”，未来有望用于治疗其他类似的代谢问题，例如尿素循环缺陷或高氨血症。

这项研究已于4月24日发表在科学期刊《细胞》（Cell），团队也已申请专利，接下来将评估这种疗法的长期效果，并探索更多应用可能。

澳洲西部鼠患严重 政府担忧冲击粮食供应

澳大利亚政府说，澳洲西部地区鼠患严重令人担忧，将继续与业界合作以遏制鼠患对粮食供应的影响。

路透社报道，澳洲能源部长鲍恩星期六（5月2日）在悉尼发表电视讲话说：“我们当然对澳洲西部，包括西澳州的鼠患情况感到担忧。”

鲍恩说：“这对农民、业界、政府来说都是非常棘手的问题。”他强调，政府正继续与业界紧密合作，努力减少鼠患对国内外粮食供应的影响。

澳洲是世界第四大小麦出口国，老鼠过量繁殖是澳洲粮食种植区的一个长期问题。

澳洲媒体指鼠患已侵袭西澳小麦种植带的农场。当地粮食生产商4月已警告，鼠患可能导致作物减产，并呼吁政府提供更强效的灭鼠药。

澳洲科学机构的资料显示，1993年澳洲发生了史上最严重的老鼠灾害（Mouse Plague），不仅数千公顷的农作物被摧毁，老鼠还袭击了鸡猪养殖场里的牲畜。

Pentagon orders withdrawal of 5,000 U.S. troops from Germany as Trump escalates feud with Merz

May 1, 2026 9:05pm EDT / Fox News

The Pentagon will withdraw 5,000 U.S. troops from Germany, a spokesperson confirmed to Fox News Digital.

The redeployment comes amid President Donald Trump’s escalating feud with German Chancellor Friedrich Merz and other NATO allies after tensions over their response to the conflict involving Iran.

“The Secretary of War has ordered the withdrawal of approximately 5,000 troops from Germany,” chief Pentagon spokesman Sean Parnell told Fox News Digital.

“This decision follows a thorough review of the Department’s force posture in Europe and is in recognition of theater requirements and conditions on the ground.

“We expect the withdrawal to be completed over the next six to twelve months.”

About 38,000 U.S. troops are stationed in Germany, where U.S. European Command is headquartered at Ramstein Air Base. The base and other American installations have long served as key logistics hubs and command centers supporting U.S. military operations in Europe and the Middle East.

The U.S. troop presence in Germany has been a point of political debate in recent years. In 2020, Trump ordered the withdrawal of roughly 12,000 troops from the country, but the plan faced bipartisan resistance in Congress and was not completed before President Joe Biden took office.

Merz, speaking Monday in Marsberg, criticized the U.S. approach to Iran, saying Washington was being “humiliated by the Iranian leadership” and expressing hope the conflict would end “as quickly as possible.”

Trump’s comments followed those remarks, marking the latest flash point between the two leaders, who have previously clashed on issues, including tariffs and defense spending.

On Wednesday, Trump said in a Truth Social post his administration was “studying and reviewing the possible reduction of Troops in Germany,” adding that a decision would be made “over the next short period of time.”

He also sharply criticized Merz, saying he “doesn’t know what he’s talking about” regarding Iran’s nuclear ambitions.

“The Chancellor of Germany, Friedrich Merz, thinks it’s OK for Iran to have a Nuclear Weapon,” Trump wrote in a Truth Social post Tuesday.

Bard College president to retire after revelations of his ties to Epstein

May 1, 2026 / 10:31 PM EDT / CBS/AP

The longtime president of Bard College announced his retirement Friday, months after it was revealed that he had a much deeper relationship with convicted sex offender Jeffrey Epstein than was previously known.

Leon Botstein, 79, who has been president of the small, liberal arts college in New York for a half century, will retire at the end of June, he wrote in a lengthy letter to the campus community.

In the letter, Botstein didn’t mention the scrutiny of his ties to Epstein, except to say that he had waited to announce his retirement publicly until the completion of an independent review of his relationship with the notorious sex offender that was published Thursday.

“I believe it was prudent and in the best interest of Bard to wait until the Wilmer Hale review was complete to make this announcement,” he wrote.

He said he would remain on Bard’s faculty as a teacher and musician.

“Our longtime President, Leon Botstein, announced today that he will be retiring from the presidency at the end of June,” the school said in a separate statement. “Over the course of fifty years, President Botstein has been a transformative leader with the vision and unwavering commitment that has shaped Bard into the world-class educational institution it is today.”

Bard’s trustees had enlisted the outside law firm WilmerHale to conduct an independent review of the communications between Epstein and Botstein. The review found that the president did not do anything illegal but “made decisions in the course of that relationship that reflect on his leadership of Bard,” according to a summary provided by the college.

“In his public statements and his statements to the Bard community, President Botstein minimized and was not fully accurate in describing his relationship with Epstein,” the review said.

Botstein was not accused of any involvement in Epstein’s exploitation and abuse of girls and women. But he was among a long list of prominent and notable men and women who maintained friendly relationships with him for years, despite his status as a convicted sex offender.

A trove of documents released by the Justice Department this year showed that Botstein and Epstein had met on multiple occasions, with Epstein sometimes arriving at Bard by helicopter. The president had also asked Epstein to be a guest at the 2013 graduation ceremonies and suggested they meet for an opera performance.

In addition, Botstein reached out to Epstein weeks after The Miami Herald reported new details on Epstein’s criminal prosecution in 2018, saying “I want you to know that I hope you are holding up as well as can be expected,” and had separately referred to his “friendship” with Epstein in at least two emails.

Epstein steered $150,000 to Botstein in 2016, which the president has previously said he donated to the college. Botstein has previously denied having a personal connection with Epstein, instead saying his contacts with Epstein were centered on fundraising for the college.

At one point, according to the review, Botstein disagreed with a senior faculty member who felt Bard should not engage with Epstein, concluding that the president “relied on his view that a person convicted of crimes involving sex with a minor—’an ordinary sex offender’, in his words—could be presumed to be rehabilitated in the same way that any other convicted person should, in his view, be given that presumption.”

“President Botstein forcefully argues that Bard’s need for funds was paramount. His view was, ‘I would take money from Satan if it permitted me to do God’s work,’” the review said.

The Executive Committee of the Board of Trustees at Bard, in a separate message, wrote that it is grateful for Botstein’s decades of service to the college, but added that the “concerns raised in recent months have been serious and deeply felt.”

“We are grateful to those who came forward to share their perspectives, and we recognize the importance of the questions that prompted this review and the deliberation that followed,” the committee wrote.

It said funds associated with Epstein will be directed to organizations that support survivors of sexual harm.

美国将从德国撤出约5000驻军

美国将从德国撤出约5000驻军

五角大楼发言人说，预计从德国撤在5000驻军的行动将在六到12个月内完成。 （路透社）

美国战争部长赫格塞斯已下令在未来一年内，从德国撤出约5000名美军士兵。

法新社报道，五角大楼发言人帕内尔星期五（5月1日）发表声明说，预计撤军将在未来六到12个月内完成。这一决定是在对美国在欧洲的兵力部署进行全面评估后做出的，同时也考虑到战区的实际需求和实际情况。

美国总统特朗普本周前威胁要从北约盟国德国撤军，原因是德国总理默茨称德黑兰在谈判桌上“羞辱”了华盛顿，激怒了特朗普。

特朗普4月28日指默茨“认为伊朗拥有核武器没问题，“根本不知道自己在说什么”；29日，特朗普称正在“研究和评估”从德国撤军的可能性，很快就会做出决定。德国外交部长瓦德富尔30日说，德方“已对此做好准备”。

另据新华社报道，五角大楼官员介绍，部分撤离欧洲的美军部队可能会先返回美国，随后再重新部署至海外。此举旨在配合五角大楼的战略重点，将资源和精力集中于美国本土及印太地区。

美方官员说，此次撤军行动不会影响受伤美军人员被送至位于德国的兰施图尔地区医疗中心。该医疗中心是美国在海外设立的最大规模医院，曾收治在美国对伊朗战事中受伤的美军官兵。

在特朗普第一任期和本届任期，他都多次威胁要削减驻德国和其他欧盟国家的美军人数，称希望欧盟承担更大的国防责任，而不是依赖美国。

美国在德驻军是二战后同盟国军事占领德国以及美国构建军力全球部署的产物。目前，美军欧洲司令部和非洲司令部均设在德国斯图加特市。

德国拉姆施泰因空军基地是美国在中东、北非和南亚军事行动的主要后勤基地。据美国国防部数据，2025年底，美军共有超过3万6000人驻扎在德国。

美国加大制裁古巴 古外长：坚决反对特朗普单边强制措施

美国总统特朗普星期五（5月1日）签署行政命令，以“威胁美国国家安全和对外政策”为由，加大对古巴制裁。

路透社引述两名美国官员说，新制裁措施是针对支持古巴政府安全机构、参与腐败或严重侵犯人权行为的个人、实体和附属机构，以及古巴政府代理人、官员或支持者。目前尚未公布具体制裁名单。

根据白宫1日发布的公告，美国政府除冻结在古能源、国防、矿产、金融等多领域经营的实体或个人资产和权益外，还禁止美国实体或个人与受制裁对象有资金、商品或服务往来，并限制受制裁对象入境美国。同时，相关联的外国金融机构也将受制裁。

古巴外长罗德里格斯在X平台表明，古巴坚决反对美国政府对古巴新采取的单边强制措施，称美国意图再次对古巴人民实施集体惩罚。

他说，美方宣布的措施违反《联合国宪章》，美国无权对古巴或任何第三国和相关实体施加这样的措施。

罗德里格斯说：“他们吓不倒我们。”

当天，古巴民众上街示威，谴责美国对古巴的经济封锁及能源限制。

美国长期对古巴实施经济、金融封锁、贸易禁运。今年年初，特朗普政府对委内瑞拉发动大规模军事打击后，进一步加大对古巴施压，包括实施新一轮石油限制措施。

特朗普多次威胁称，完成对委内瑞拉和伊朗的军事行动后，“下一个就是古巴”。

Trump teases US will be ‘taking over’ Cuba ‘almost immediately’ in Florida speech

May 1, 2026 9:12pm EDT / Fox News

President referred to Cuba after honoring former Congressman Dan Mica

By Jasmine Baehr

President Donald Trump appeared to joke during remarks at the Forum Club of the Palm Beaches in Florida Friday that the U.S. would be “taking over” Cuba “almost immediately,” while recognizing attendees including former Rep. Dan Mica.

“And he comes from, originally, a place called Cuba, which we will be taking over almost immediately,” Trump said.

“Cuba’s got problems. We’ll finish one first. I like to finish a job.”

Trump then riffed on a hypothetical show of American force.

“On the way back from Iran, we’ll have one of our big — maybe the USS Abraham Lincoln aircraft carrier — the biggest in the world,” he said.

“We’ll have that come in, stop about 100 yards offshore, and they’ll say, ‘Thank you very much, we give up.’”
