The Final Episode of The Late Show Celebrities, politicians, and New Yorkers paid their respects to Stephen Colbert as the Late Show aired its final episode on Thursday. The long-running chat show, which started back in 2015, was cancelled last year by CBS, purportedly because of a financial decision. But many believed it was a result of the network's increasing closeness with Donald Trump, who Colbert regularly criticised. A Bittersweet Goodbye Last night's episode saw the host bid an emotional farewell with the help of celebrity guests including Paul McCartney, Paul Rudd, Ryan Reynolds, and Bryan Cranston. "We love doing the show for you but what we really love is doing the show with you," he said to the audience at home. Colbert hosted more than 1,800 episodes of the Late Show, taking over the mantle from David Letterman. Tributes from Around the World Former president Joe Biden, who had previously guested on the show, also joined the chorus this week with a tribute on Instagram. "There aren't many who can make people think and laugh at the same time," he wrote. "For years, Stephen brought wit, heart, and honesty to late night television. America could always count on a laugh – and sometimes a needed reality check. Congrats on an incredible run, my friend." The Impact of Colbert's Comedy Jane Fonda was among celebrities featured in a video put together by her newly relaunched Committee for the First Amendment. "He made us laugh and he never flinched," the Oscar-winning actor said. "We've watched this administration suppress dissent repeatedly." Colbert already has his next gig lined up with the long-term JRR Tolkien fan set to co-write a new Peter Jackson-produced film tentatively titled The Lord of the Rings: Shadow of the Past. The Future of Late-Night Television The Late Show is being replaced by Comics Unleashed, an unscripted comedy series from comedian and media mogul Byron Allen. The entire set from the show is being donated to the Museum of Broadcast Communications in Chicago.

What is Immunotherapy? Immunotherapies are biological treatments that harness the immune system to prevent, control and fight diseases and other conditions. The most familiar are vaccines, which train the immune system to recognise targets such as invading pathogens. Other immunotherapies boost immune responses when they are too weak, or dampen them down when they are out of control. Still others draw on engineered immune cells or lab-made antibodies to disrupt disease processes. The Evolution of Immunotherapy Efforts to prevent disease by boosting the immune system date back thousands of years, but advanced therapies for a wide range of illnesses have come to the fore in the past two decades. A global registry of clinical trials listed 1,257 trials of immunotherapies between 2006 and 2016. The figure leapt to 4,591 in the past decade. How Do Cancer Immunotherapies Work? Cancer patients have seen great benefits from immunotherapies and dozens are now approved for more than 30 types of cancer. Some tumours evade the body’s defences by switching off immune cells, but antibody-based drugs – called checkpoint inhibitors – reactivate them so they can recognise and attack the malignancies. The Future of Immunotherapy: Beyond Cancer Researchers are now testing whether existing immunotherapies can help a broader range of patients. This includes treating allergies, infections, brain diseases, and autoimmune disorders. Some of the most exciting new immunotherapies draw on recent Nobel prizewinning work on regulatory T-cells, or Tregs, which can be used to dampen down immune responses. The Potential of Tregs in Immunotherapy Tregs are unusual immune cells that stand the immune system down once the threat has been dealt with. Therapies are in the pipeline for dementia and autoimmune diseases from type 1 diabetes and rheumatoid arthritis to lupus and chronic inflammation. The potential for Tregs is vast, and researchers believe that half of all deaths have a component that is immunological.

The Sudden Loss of a Racing Legend Longtime teammates, former rivals and others around the sports world have joined the wave of condolences over the sudden death of Nascar driver Kyle Busch on Thursday. Busch, a two-time Cup Series champion who was the winningest driver across the sport's three series in history, died at 41 after being hospitalized earlier Thursday with a severe illness. No cause of death has been announced. Tributes from the Racing Community "Absolutely cannot comprehend this news," Denny Hamlin, a 22-year Nascar veteran and Busch's former teammate, said on social media. "We just need to think of his family during this time. We love you KB." "There aren't really words for today. I've raced against Kyle for a long time, and anyone who's lined up next to him knows exactly what made him special, he gave you everything he had, every single lap, and he made all of us better for it," driver Ricky Stenhouse Jr said in a post. "But more than the wins and the records, I keep thinking about Samantha, Brexton, and Lennix, and the entire Busch family right now. That's where my heart is. Rest easy, Rowdy. The sport won't be the same without you." A Legendary Career Busch was in his fourth season at Richard Childress Racing. He ranked 24th in the Cup Series standings, with two top-10 finishes in 12 races this season, and had been the Cup Series champion in 2015 and 2019 with Joe Gibbs Racing. He won a Nascar Truck Series race at Dover International Speedway last week and was slated to compete in this weekend's Coca-Cola 600 in Charlotte, North Carolina, before his family announced on Thursday he had been hospitalized. The Impact on the Racing World Dale Earnhardt Jr, an on-track rival after he took over Busch's car after he departed Hendrick Motorsports in 2007 who later became a friend, called Busch one of the "greatest drivers in Nascar history". "Kyle and I had a really challenging existence for many years. But we luckily took the time to figure out our differences and that was something he instigated with a conversation in his bus around how we each managed our racing teams. I was super eager for us to get on better terms. But it was he who made the effort for that to be possible," Earnhardt said. "I will never be able to make sense of this loss but I am thankful that we had found a way to become friends."

The Underwhelming Experience of Cannes 2026 The 2026 Cannes film festival has come to a close, leaving many with a sense of disappointment. This year's event was marked by a lack of standout films, with even seasoned veterans like László Nemes, Pedro Almodóvar, and Asghar Farhadi delivering average performances. The Absence of Hollywood Glamour One notable absence was the lack of big-budget Hollywood films in the official selection. Typically, films like Mission: Impossible or Elvis would add a touch of glamour to the festival, but their absence was felt this year. The Disappointing Auteurs Films from renowned directors like Ryusuke Hamaguchi's 'All of a Sudden' and Cristian Mungiu's 'Fjord' received mixed reviews, with some critics calling them contrived and lacking in substance. The Data Analysis: A Look at the Numbers While there aren't specific numbers to analyze, the overall sentiment among critics and attendees suggests that this year's festival was a letdown. The Impact Analysis: A Shift in the Film Festival Landscape The underwhelming experience of Cannes 2026 raises questions about the future of the film festival. Will it continue to be a premier event for filmmakers and industry professionals, or will it struggle to regain its momentum? The Prediction: What's Next for Cannes Based on this year's lineup, it's clear that Cannes needs to adapt and evolve to stay relevant. The festival may need to consider new ways to attract top talent and engage audiences. Standout Films and Awards Despite the overall disappointment, some films stood out, including Andrey Zvyagintsev's 'Minotaur,' Paweł Pawlikowski's 'Fatherland,' and Rodrigo Sorogoyen's 'The Beloved.' These films showcased exceptional direction, acting, and storytelling. Palme d'Or: Minotaur (dir. Andrey Zvyagintsev) Grand Prix: Fatherland (dir. Paweł Pawlikowski) Jury Prize: The Black Ball (dirs. Javier Calvo, Javier Ambrossi)

The Latest Escalation in Lebanon Israeli attacks have killed at least 11 people in southern Lebanon, including several healthcare workers. The attacks occurred on Friday in the Tyre district and are the latest in a long line, questioning the durability of the shaky United States-mediated ceasefire between Israel and Lebanon. Details of the Attacks At least 11 people killed in Israeli attacks in southern Lebanon Several healthcare workers among the dead, including paramedics and a child Attacks occurred in the Tyre district, including in the municipality of Deir Qanoun en-Nahr and the town of Hannaouiyah The Humanitarian Impact More than 400 people have been killed by Israeli fire since the ceasefire came into force in mid-April. Israel insists it will continue to target the Hezbollah armed group, which opposed the Lebanese government’s agreement on the ceasefire. At least 2,896 people killed in Lebanon since Israeli attacks began More than 8,824 injured and over 1.6 million displaced – about one-fifth of the country’s population The Systematic Destruction of Health Facilities The Israeli military has repeatedly attacked health facilities and medical teams in Lebanon, accusing Hezbollah of using them to conceal weapons and fighters. The Lebanese government rejects that claim. 116 healthcare workers killed since the latest escalation in early March 16 hospitals damaged and 147 ambulances attacked The Future Outlook A ceasefire brokered by the United States came into effect in mid-April, but the violence has continued, and Hezbollah has continued to trade attacks with Israel. The US has imposed sanctions on individuals with links to Hezbollah, including Iran’s ambassador to Lebanon.

The LeadMajor US social media companies including Meta's Facebook and Instagram platforms have blocked the accounts of Saudi Arabian dissidents so they are no longer visible inside the kingdom, following orders by Saudi authorities. Those affected include Abdullah Alaoudh, a US-based activist and vocal critic of Saudi human rights violations, and Omar Abdulaziz, a Canada and UK-based activist who worked closely with Jamal Khashoggi before the journalist's murder by Saudi agents in 2018.The Platform Response to Government DemandsAt least seven accounts had been blocked by Meta at the end of April, including those of two American citizens and two individuals based in Europe, according to the advocacy group American Committee for Middle East Rights (ACMER). Meta did not respond to the "dirty work" claim, but provided a statement to the Guardian saying that when "something happens" on one of its platforms that is reported as violating local law but not the companies' own community standards, the company may restrict the content's availability in the country where it is alleged to be unlawful.Meta operates a public "transparency center," where it acknowledges that Saudi authorities contacted the company and sought restrictions on a total of 144 Instagram accounts, Facebook pages, and Facebook profiles during April. The site also shows that Meta restricted access to 108 "items".Inconsistent Approaches to Government RequestsInterviews with some of the dissidents targeted suggest the companies approached by Saudi authorities did not all respond in the same way. While Meta did alert users that their content was being blocked due to a "local legal requirement, or a request from a government," Snapchat appears to have slowed or removed accounts in Saudi Arabia – including one used by Abdulaziz – without alerting the account owners of the change. It is not clear how many Snapchat accounts were affected, and its owner, Snap Inc, declined to comment.At least two users of X, which is owned by Elon Musk, received letters informing them that the platform had received a request from the Saudi communications, space and technology commission claiming their accounts violated Saudi laws. X told users including Abdulaziz that it had not taken any action on the reported content yet, writing that the company "strongly believes in defending and respecting the voice of our users". It then urged addressees to seek legal advice if they wished, or to delete the relevant content voluntarily.Human Rights Concerns and ImplicationsAbdulaziz told the Guardian: "I think this is just the introduction to a massive crackdown by the Saudi government to mute opposition. It could go as far as committing atrocities, just like they did with the murder of Jamal Khashoggi." The Saudi government did not respond to a request for comment, sent through the Saudi embassy in Washington.Other accounts targeted include those of individuals linked to the London-based human rights organisation ALQST, including its founder, Yahya Assiri. Dr Maryam Aldossari, an ALQST board member, stated: "These [account holders] are not dangerous actors; they are people documenting abuses, challenging state propaganda and giving voice to Saudis inside the country who cannot speak freely. Blocking these accounts would not protect public safety, it would project authoritarian power from scrutiny."The Future of Digital DissentDr Aldossari further commented: "This is how authoritarian censorship travels: through legal notices, platform pressure and the attempted outsourcing of repression to global technology companies." As social media platforms continue to navigate the complex landscape of international laws and human rights standards, the case of Saudi dissidents highlights the growing challenge of maintaining free expression in an increasingly interconnected digital world where governments increasingly seek to control online discourse beyond their borders.

The Marine Heatwave's Persistence and ExpansionAn enormous marine heatwave off the US west coast is ringing alarm bells among ocean and atmospheric scientists as new data shows its ecological and environmental effects are intensifying. The unusual area of warm water has persisted since peaking in size during September 2025 and still stretches thousands of miles from the California coastline – more than halfway across the Pacific – affecting a vast triangle-shaped region of oceanic habitats from Hawaii to British Columbia and southward to Mexico.The Event DetailsAs recently as early April, marine scientists had hoped that the heatwave might diminish and the worst of its effects may be avoided. However, new projections released last week by the National Oceanic and Atmospheric Administration (Noaa) show it is now expected to expand and strengthen in the months to come.The Data AnalysisScientists say the effects may already be far reaching. A surge in the marine heatwave would accompany the formation of El Niño in the tropical Pacific – resulting in an atmospheric and oceanic mélange that could influence everything from record-breaking temperatures on land to disrupted marine food chains.The Impact AnalysisAdditional data acquired in recent weeks has left climate scientists gobsmacked and re-examining their assumptions of how the complex interplay between the ocean and the atmosphere could accelerate the effects of human-caused climate crisis. Climate scientists said the persistent marine heatwave has contributed to shockingly extreme temperatures downstream across most of the United States.The Prediction“There’s real concern right now that even if this marine heatwave didn’t persist, we’re heading into a bad wildfire season with poor water supply conditions,” said Larry O’Neill, an Oregon State University climatologist. “Our summer is going to be much warmer than normal.”

The Arrest That Sparked International ConcernThe operation began at 9am Moscow time, but took place across all of Russia's 11 time zones. Almost simultaneously, agents of the federal security service (FSB) raided the homes and workplaces of 17 Indigenous rights activists. Officers carried out searches, confiscated laptops and phones, and arrested and interrogated activists about participation in international forums. Most were let go; many have since left the country. Others remain in Russia, but will no longer speak up.Six months later, one remains in jail. Daria Egereva, one of Russia's foremost Indigenous rights activists, is accused of membership of a terror group. No trial date has been set. Her supporters say the charges are fabricated and she has been targeted for speaking out.Egereva was not just any activist. A member of the Selkup indigenous group, from western Siberia, she was a "bright star" of Russia's indigenous rights movement. As a member of the UN's Indigenous Peoples' Coordinating Body, she had international status. Weeks before her arrest, she had played a key role at Cop30 in Brazil as co-chair of the Indigenous People's Forum on Climate Change.Her jailing has shone a spotlight on the plight of Russia's Indigenous people, threatened by authoritarianism, extractivism and climate breakdown.The Climate Crisis in Russia's Arctic"They are really seeing the worst effects of climate change," said Alicia Moncada, director of global advocacy at Cultural Survival, which campaigns for Indigenous rights. "They are on the frontline of the frontline – that's why [Egereva's] advocacy was super important."The polar north is heating faster than any other part of the planet. In recent decades, temperatures in Arctic regions have risen three to four times faster than the global average. Communities based on permafrost are seeing their world collapse around them."The elders are saying that nature has stopped trusting us," said one exiled Indigenous leader, who requested that his name be withheld. "The traditional ways of predicting nature are not working any more."Many settlements sit next to the banks of rivers and lakes. Due to the melting permafrost, those banks are beginning to crumble. "There is a real threat of destruction for a lot of those villages," said the leader, who spoke through an interpreter. And the melting ice has brought a new source of tension: newly accessible critical mineral resources.Resource Extraction and Indigenous Displacement"All these resources of the Russian Federation, a majority of them are located under the lands of Indigenous people: gold, diamonds, oil, gas, coal," the leader said. "For some people it is a treasure, but for us it is a curse."Because the companies are coming to our land for those resources and they are pushing us out. Even if they don't push us out, the environmental situation in those places will become so bad that we are unable to hunt or fish."One of the elders said that we can adapt to anything, but we will not be able to survive without our land."The Government Crackdown on Indigenous ActivismAlthough Indigenous groups maintained their identities, by the end of the Soviet era they lacked independent organisation and relied on the state. Egereva had been part of a new generation of leaders who had encouraged community self-empowerment.But this assertiveness brought them into conflict with the authorities. Even before the war in Ukraine, the Russian state claimed that its enemies were exploiting environmental and indigenous issues. Now, with the war a pretext for a crackdown on civil society, Indigenous people are among those at the sharp end.To date, 830 organisations and 20,813 individuals have been put on the "list of terrorists and extremists", according to the UN. Among them was Aborigen Forum, a network of Indigenous defenders designated an "extremist organisation" in July 2024.Russian authorities have based their charges against Egereva and her co-defendant, Natalia Leongardt, a civil rights activist, on their involvement with Aborigen. Authorities claim it is part of an anti-state "post-Russia free nations forum".International Response and Russian DefenseIn a bail hearing on 29 April, Egereva and Leongardt denied being part of any anti-state conspiracy. "I am not familiar with and do not know this organisation," Egereva told the court. "What we are being accused of is completely untrue ... I ask to be allowed to return home and embrace my children."The court refused to grant them bail, remanding them in custody until at least mid-June. The following day, Russia celebrated a new federal holiday: the "Day of Indigenous Small-Numbered Peoples".The Russian embassy told the Guardian: "The investigation concerning Daria Egereva is an internal Russian legal matter, conducted in full accordance with Russian law. As proceedings are ongoing, we are not in a position to comment on the specifics of the case."Russia firmly rejects any allegations of violations of Indigenous people's rights. Unlike a number of western states – including Britain in its former colonies – Russia has no history of forced assimilation of Indigenous communities. Russian law affords Indigenous peoples special legal protections, guaranteeing their collective and individual rights, cultural identity, and linguistic heritage under the constitution and in line with international norms."Russia is actively engaged in the international climate agenda, taking account of both the challenges and the economic opportunities emerging in its northern regions – including expanded access to the northern sea route and mineral resources in permafrost zones. All such projects are carried out with the aim of supporting regional development, creating jobs and attracting investment, including for the benefit of Indigenous communities in these areas."
