Israel's ambassador to the United States, Yechiel Leiter, has taken a significant step towards diplomacy with Lebanon, holding a first-ever phone call with his Lebanese counterpart, Nada Hamadeh Moawad. This development marks a break from tradition, as Israel and Lebanon do not have formal diplomatic relations.The talks are set to take place as global pressure mounts on Israel to end its invasion of Lebanon, which has resulted in over 2,000 people killed and over one million people displaced. Leiter, a settlement activist and longtime figure in Israeli political circles, has been at the center of US-Israel relations.Leiter's background includes senior advisory roles in government and associations with far-right politics. His tenure as Israel's ambassador in Washington, DC, began in January 2025, replacing Michael Herzog. Netanyahu's office described Leiter as a 'talented diplomat' with a 'deep understanding of American culture and politics'.However, Leiter has drawn controversy during his time in public service, including over his past affiliations, ideological positions, and rhetoric during Israel's conflicts. He was involved with the Jewish Defense League (JDL) in his youth, a US-based far-right pro-Israel group later classified by US authorities as a 'terrorist' organization.The talks between Leiter and Moawad aim to address the ongoing conflict between Israel and Lebanon. Israel has carried out near-daily attacks on Lebanese territory since a ceasefire started in November 2024, violating the truce hundreds of times. The situation remains complex, with Hezbollah rejecting direct negotiations between Lebanon and Israel.Analysts express skepticism about the success of the talks, stating they 'are designed to fail.' However, they also note that if there is a positive outcome, it will likely be due to US pressure on Israel. The Arab Peace Initiative, proposed in 2002, which offered recognition of Israel in exchange for a two-state solution, has been rejected by Israel.

The National Gallery of Art's latest exhibition, 'Dear America: Artists Explore the American Experience', is a thought-provoking collection of over 100 works by 95 artists. This 'open letter to the nation' offers a multifaceted exploration of the American experience, delving into themes of land, community, and freedom.Upon entering the exhibition, visitors are immediately struck by the unconventional representations of iconic American symbols. The Statue of Liberty, for instance, is reimagined through the lens of South African photographer Zanele Muholi and a geometric screenprint by Roy Lichtenstein.The exhibition's curatorial approach is to create 'provocative conversations across centuries, disciplines and demographics.' E Carmen Ramos, the gallery's chief curatorial and conservation officer, notes that the show was 'years in the making' and showcases an 'embarrassment of riches' from the gallery's permanent collection of over 160,000 works.Structured around three core themes – land, community, and freedom – the exhibition presents a diverse array of works. These include Thomas Moran's idyllic watercolours of the American West juxtaposed with Thomas Hart Johnson's photographs of a landscape ravaged by coal mining and railroads. The exhibition also features poignant pieces such as Carrie Mae Weems's haunting silhouette and Gordon Parks's indelible 'American Gothic.'The show's second section, 'Community,' features Richard Avedon's massive 1976 commission 'The Family,' which comprises 69 stark, uniform portraits of the bicentennial era's political, media, and corporate elite. This is contrasted with John Wilson's tender sketches of his teenage children and their friends.The final act of the exhibition turns its lens to 'Freedom,' showcasing historical portraits of figures such as Frederick Douglass, Sojourner Truth, and George Washington, alongside powerful works by Kara Walker, Martha Rosler, and Faith Ringgold. As visitors exit, they are met with Robert Indiana's boldly coloured screenprint 'Liberty '76,' created for the 1976 bicentennial.Ramos reflects on the exhibition's significance, stating that it 'explores how artists in the United States have explored the American experience across different moments in time.' The exhibition will be on view in the National Gallery's West Building until 20 September.

Lake Erie, a vital source of freshwater for millions of people, has faced significant pollution challenges for decades. In the 1960s, the lakes and rivers around Cleveland were so polluted that they frequently caught on fire. While water quality has improved since then, the lake still struggles with poor water quality due to chemical runoff and pollution. The 2025 State of the Great Lakes report found that Lake Erie ranks poorly for pollution caused by chemical runoff and is consistently one of the top five most polluted lakes in the US. Over 5.5 billion gallons of freshwater are drawn from the lake daily to meet industrial and consumer needs, highlighting the importance of addressing these pollution issues. In response, the Cleveland Water Alliance, a non-profit organization, is working with over 300 companies, research institutions, and government agencies to develop clean water solutions for Lake Erie. The alliance has deployed hundreds of sensor buoys across the western section of the lake to observe and detect various water-related factors, including E. coli, algal blooms, and turbidity levels. Researchers at Case Western Reserve University have incubated research for a pilot program technology that can capture 90% of microplastics down to 50 microns in washing machines, preventing these materials from entering the lake. Other projects are recording solar radiation, dissolved oxygen levels, and water and air temperatures. Korean companies have also come to the area to test electrochemical water treatment methods in Lake Erie's water. The alliance's efforts aim to position Lake Erie as an open-air research facility, driving innovation and solutions to address the lake's pollution challenges. Despite these efforts, environmentalists say the challenges to cleaning up the lake are huge. A 40% reduction in phosphorus is needed to minimize blooms, with about 90% of phosphorus entering the western Lake Erie basin coming from agricultural runoff. The manure problem is also a growing concern, with the increasing number of livestock operations in the area contributing to pollution. The Cleveland Water Alliance's initiatives, such as the development of a system for making commercial-grade sodium hypochlorite on site, aim to promote technologies for wintertime monitoring of aquatic life activity and behavioral changes as well as levels of water turbidity. By leveraging data and innovation, stakeholders hope to improve the lake's water quality and mitigate the impacts of pollution.

The recent ceasefire talks between the United States and Iran have ended without a breakthrough, with Iran's chief negotiator, Mohammad Bagher Ghalibaf, blaming the US for the failure of the talks held in Islamabad, Pakistan. The talks, which were the first direct engagement between the two countries at this level since the 1979 Iranian Revolution, exposed deep divisions on core issues.The US framed the lack of a breakthrough primarily around Iran's alleged refusal to meet its core demand: a firm commitment not to develop nuclear weapons. US Vice President JD Vance said Washington had made its 'red lines' clear and presented what he described as a 'final and best offer'. However, Iran downplayed expectations and blamed the US for making unreasonable demands.The main sticking points between Tehran and Washington are:Iran's nuclear programme: The US wants a clear and enforceable commitment that Iran will not develop nuclear weapons – or even the capability to do so quickly. Iran has consistently rejected accusations that it seeks to build nuclear weapons but said it is willing to negotiate limits on its nuclear activities if sanctions are removed.Strait of Hormuz: Who gets to control this strategic waterway, through which almost all of the oil and natural gas exports from the Gulf nations pass, has become a major flashpoint. Iran has floated the idea of charging transit fees to allow ships to pass through the strait, while the US is adamant the strait is reopened free of any tolls.The near shutdown of shipping through the strait has sent global energy prices soaring with many countries, especially in Asia, forced to implement unprecedented austerity measures to soften the impact of fuel shortages. Experts said the near-closure of the strait has caused the worst economic shock since the 1973 oil embargo.

Asha Bhosle, the iconic voice of Bollywood for over seven decades, has died at age 92 in Mumbai, according to her family. The two‑time Grammy nominee passed away on Sunday at Breach Candy Hospital, where she had been admitted for "extreme exhaustion" and a chest infection. Her son, Anand Bhosle, confirmed the news to reporters, stating, "My mother passed away today. Her last rites will be held tomorrow at Shivaji Park in Mumbai." Throughout her prolific career, Bhosle recorded more than 12,000 songs in multiple Indian languages, shaping the soundscape of Bollywood cinema from the 1970s through the 1980s and beyond. Prime Minister Narendra Modi expressed his sorrow, describing himself as "deeply saddened" by the loss of a cultural legend whose music resonated across generations. The nation now prepares to bid farewell to a figure whose contributions to Indian music remain unparalleled, with funeral services set for Shivaji Park, a venue symbolic of her enduring legacy.

Three Very Large Crude Carriers (VLCCs) successfully navigated the Strait of Hormuz on Saturday, marking a rare movement of oil cargoes amid the fragile truce between the United States and Iran.The vessels – the Liberia‑flagged Serifos, and the China‑flagged Cospearl Lake and He Rong Hai – each can transport about 2 million barrels of crude, collectively representing a significant volume for a waterway that channels roughly 20% of the world’s oil and LNG shipments.According to data from the London Stock Exchange Group (LSEG) and analytics firm Kpler, the Serifos is chartered by Thailand’s state‑owned energy firm PTT. Loaded with Saudi and UAE crude in early March, it is slated to dock at Malaysia’s Malacca Port on April 21.The other two carriers, Cospearl Lake and He Rong Hai, are chartered by Unipec, the trading arm of Chinese energy giant Sinopec. Cospearl Lake, carrying Iraqi oil, is expected to reach China’s Zhoushan port on May 1, while the destination for He Rong Hai remains undisclosed.Earlier, a tanker named Ocean Thunder, chartered by a Petronas subsidiary, also transited the strait, underscoring a gradual, albeit limited, resumption of traffic.Despite these movements, hundreds of tankers remain stranded in the Gulf, awaiting clearance during the two‑week ceasefire. Their prolonged idling continues to pressure global energy prices, which have surged since Iran’s blockade began in late February.In addition to the loaded vessels, three empty tankers – Mombasa B, Agios Fanourios I, and Shalamar – were observed heading into the strait on Sunday to load fresh cargoes. Notably, Agios Fanourios I signaled a route to Iraq’s Basrah fields to pick up crude destined for Vietnam.Management firms such as Eastern Mediterranean Maritime, Cmb.Tech NV, and Pakistan National Shipping have not provided comments on the recent transits.While the passage of these three supertankers offers a modest relief to the global oil supply chain, the overall situation remains precarious. The continuation of the ceasefire and the resolution of Iran’s blockade will be critical determinants of oil market stability in the weeks ahead.

The light‑heavyweight division entered a new chapter on Saturday night in Miami when Carlos Ulberg secured the vacant UFC title by delivering a decisive left hook to former champion Jiri Prochazka. President Donald Trump watched from the cageside as Ulberg’s strike landed at the 3:45 mark of the opening round, ending the bout with a knockout and awarding him the undisputed belt. Ulberg entered the fight with a professional record of 14‑1 in MMA (10‑1 in the UFC), while Prochazka held a 32‑6‑1 MMA record (6‑3 in the UFC). Early in the first round Ulberg felt a knee give way, yet he persisted, capitalising on Prochazka’s hesitation to land the winning blow. “I blew out my knee, but I never counted myself out,” Ulberg said afterward. “I knew I needed one clean shot, and when I saw Jiri pulling back, I threw my left hand and it landed.” Prochazka, who has gone 1‑3 in UFC title fights since June 2022, reflected on the loss: “I felt sorry for him, and this is one of the biggest lessons in my life. The fight was in my hands, I saw his injury, and I’ll be back.” The championship was vacant after former champion Alex Pereira vacated the belt to pursue an interim heavyweight title at UFC Freedom 250, a bout scheduled for the White House on Donald Trump’s 80th birthday. Trump promoted the event on his Truth Social account and arrived at the Kaseya Center accompanied by UFC president Dana White, Secretary of State Marco Rubio, and U.S. ambassador to India Sergio Gor. A Kid Rock track blared as Trump took his seat beside the officials. In the co‑main event, Azamat Murzakanov knocked out Paulo Costa with a right round‑house at 1:23 of the third round, extending his perfect UFC record to 17‑0‑0. After his victory, Murzakanov shook hands with Trump, who praised the fighter. Murzakanov acknowledged the president during his post‑fight interview with Joe Rogan. The heavyweight showdown between Josh Hokit and Curtis Blaydes turned into a gritty slugfest, with Hokit prevailing by unanimous decision (29‑28 on all three cards). Trump cheered loudly as the fighters exchanged blows. Following Hokit’s win, UFC chief Dana White announced on social media that a bout between Hokit and Derrick Lewis would be added to the UFC Freedom 250 card, noting that President Trump helped bring the matchup together.

When a Toronto reader confessed to always using "please" and "thank you" with Alexa, the Guardian invited its audience to share their thoughts on the etiquette of speaking to artificial assistants.One camp warns against treating AI as sentient beings, arguing that these systems merely mimic social cues and that confusing imitation with reality can erode our language’s power to challenge dehumanisation. As User30000 put it, we should avoid both de‑humanising language toward people and humanising language toward machines.Conversely, several contributors argue that politeness serves as a useful human default. Lauk notes that courteous phrasing may reinforce positive behavioural cues for AI that learn from user input, while also keeping the speaker grounded in genuine social norms.From an ecological standpoint, extra words translate into measurable energy and water waste. Superspartan highlights that each unnecessary token adds processing load to already energy‑intensive models, and that the cumulative effect of polite phrasing across millions of daily interactions could be substantial.Academic research supports the idea that courteous language can improve AI performance. A linked study finds that polite prompts often elicit more helpful replies, treating modern models as "statistical parrots" that mirror the tone they receive. Yet Sam Altman has publicly estimated that responding to thank‑you notes costs OpenAI tens of millions of dollars, underscoring a tangible financial dimension to the debate.Some readers take a lighter view, extending politeness to elevators, SUVs and even low‑battery iPads, while others, like Martin from Dorset, argue that the practice protects the human soul rather than the machine.There is growing concern that habitual rudeness toward AI may spill over into real‑world interactions. Poridgeoates observes that younger users, who spend more time with technology than with people, risk weakening empathy and emotional‑intelligence muscles if they treat conversational agents dismissively.Louise adds that the way we speak to objects can shape broader social behaviour, especially where power imbalances exist. While AI itself may not feel insulted, the act of being rude can reinforce undesirable character traits in the speaker.Overall, the discussion reveals a split between those who see politeness as a harmless habit that can improve AI responses, and those who view it as an unnecessary drain on resources and a potential threat to human civility.

Former President Donald Trump and Secretary of State Marco Rubio arrived at Miami’s Kaseya Center shortly after 9 p.m. on Saturday to watch a UFC card, joining UFC president Dana White and several members of the Trump family. Seated nearby were U.S. ambassador to India Sergio Gor, rapper Vanilla Ice and former FBI deputy director Dan Bongino. The crowd greeted Trump enthusiastically as a Kid Rock track blared, and he exchanged handshakes and smiles with fans and the broadcast crew, which included podcaster Joe Rogan. While the fights unfolded, Vice‑President JD Vance told reporters that the diplomatic mission in Pakistan aimed at ending the conflict with Iran had broken down. He noted that Iran’s refusal to renounce its nuclear ambitions remained the chief obstacle, stating, "We need an affirmative commitment that Iran will not seek a nuclear weapon or the tools to achieve one quickly." Despite the diplomatic setback, Trump appeared focused on the cage action, occasionally leaning toward Rubio to discuss matters on his phone. After the co‑main event victory of Paulo Costa over Azamat Murzakanov, the champion approached the former president for a handshake. Trump’s family members at the venue included his children Ivanka, Tiffany and Donald Jr.; Ivanka’s husband Jared Kushner was in Pakistan with Vance for the failed talks. UFC has long been a platform that bolsters Trump’s appeal among young, male audiences. The promotion recently announced a special event at the White House slated for 14 June—coinciding with Trump’s 80th birthday—to commemorate the United States’ 250th anniversary. According to White, a bout featuring Josh Hokit was added to the June card at Trump’s request, with both White and Rogan confirming the arrangement. Vance emphasized that the United States remains committed to securing a binding Iranian pledge against nuclear weapon development, framing it as the core objective of the administration’s foreign policy agenda.
