The Strategic Selection of Five PartnersThe US Department of Energy has officially selected five companies to enter advanced discussions regarding the utilization of surplus Cold War-era plutonium as fuel for nuclear reactors.Oklo and newcleo are leading the initiative.Other partners include Exodys Energy, SHINE Technologies, Standard Nuclear, and Flibe Energy.Financial and Material MetricsThe announcement comes with significant market movement and material volume implications.Oklo saw its stock price surge by over 5.5 percent to $69.51 per share.The program targets approximately 20 metric tonnes of weapons-usable plutonium.The material has a half-life of 24,000 years and is currently held at guarded facilities in South Carolina, Texas, and New Mexico.Policy Shifts and Geopolitical ImplicationsThis move represents a major pivot in nuclear waste management and defense posture.The Trump administration halted a previous disposal program to provide this material for advanced reactors.Senator Edward Markey and others raised concerns, noting the material could produce roughly 2,000 nuclear bombs, citing proliferation risks.US Energy Secretary Chris Wright, a former Oklo board member, played a key role in facilitating this transition.The Path Forward for Nuclear LiabilityIndustry leaders view this as a critical step in modernizing the energy grid.Oklo cofounder and CEO Jacob DeWitte emphasized that this creates a pathway to use existing surplus material as bridge fuel, while Stefano Buono of newcleo highlighted the reduction of US nuclear liabilities. The program aims to help companies secure private funding by offering a solution to the disposal problem.

Jannik Sinner Falls to Juan Manuel Cerúndolo in French Open Upset

World No. 1 Jannik Sinner was upset by Juan Manuel Cerúndolo in the French Open second round, citin…
The Upset at Roland Garros Jannik Sinner, the No 1 men’s tennis player in the world, was still leading by two sets and serving for a place in the third round of the French Open when it became clear he was in significant danger on the baking clay in Paris on Thursday afternoon. He was undone in the second round of the only Grand Slam he has yet to win, not by the ingenuity of his opponent or even the immense pressure that comes with being the prohibitive favourite, but rather by his own body. The Impact of Extreme Heat The Italian – who had not lost a match since February – said afterward that he had been struggling with an illness. Despite waving away suggestions he had wilted in the high temperatures, the unprecedented heat wave in the first week of the French Open this year could not have helped his cause. He fell 3-6, 2-6, 7-5, 6-1, 6-1 to Juan Manuel Cerúndolo before a stunned, packed audience on Court Philippe-Chatrier. Player Reactions to the Heat His defeat represents one of the most shocking results in recent years. The 24-year-old had entered the court on a 30-match winning streak and earlier this month he became the only man other than Rafael Nadal, the greatest clay court player in history, to win all three clay court ATP Masters 1000 titles in the buildup to the French Open. Most players are used to disruptive weather at Roland Garros coming in the form of rain delays and damp courts, but this year in Paris the heat has changed the state of play and divided the locker room over its intensity. The Tournament's Heat Rules The temperature has consistently ranged between 32 and 35C most afternoons so far. Such conditions are so rare in the second Grand Slam of the year that there was significant confusion about the tournament’s heat rules at the start of the week. When asked about them on Wednesday, Novak Djokovic incorrectly thought that they did not exist: “I really don’t understand why they don’t have the heat rule,” he said. “I actually didn’t know. I thought that there is in every slam, but then someone told me that Roland Garros has no heat rule.” Adapting to the Conditions The actual rules are based around the tournament organisers using wet bulb sensors to monitor the temperature, and a match could be suspended when it crosses 32.2C. To date, however, no match has ever been suspended at Roland Garros due to the heat. The scorching temperatures also make a significant difference to the way matches are played on clay. Wet, damp and colder conditions make balls heavier, leading to longer rallies and a lower bounce, the hot weather hardens the court and allow the ball to fly more quickly.

‘Hundreds of job applications’: Young people grapple with a broken labour market

A series of personal accounts from 24‑year‑olds in Brighton, Essex, London and Glasgow reveal how c…
The Personal Stories Highlight a Growing Youth Employment CrisisFour young adults, all aged 21‑24, share how the UK labour market has become a maze of unpaid internships, short‑term gigs and relentless job applications, leaving them anxious about the future.From Film Graduates to Care Leavers: Real‑World Barriers to EmploymentCatherina, 24, Brighton – Digital film graduate who has only secured runner roles despite festival‑screened shorts.Olivia, 24, Essex – Former retail worker forced to quit after epileptic seizures; cites inadequate employer adjustments and lack of disability‑specific guidance.Giovanna, 24, London – Care‑leaver who navigated hostel life, temporary hospitality jobs and a nine‑month civil‑service training scheme.Joseph, 21, Glasgow – Neurodivergent musical‑theatre trainee who cycled through supermarket, call‑centre and software‑engineering apprenticeship amid “hundreds” of applications.Common Threads Across the NarrativesRepeatedly sending hundreds of job applications with little to no response.Reliance on charities such as Spear, Young Women’s Trust and Drive Forward Foundation for coaching, CV help and mental‑health support.Financial insecurity forcing continued low‑paid work or early return from sick leave.Systemic gaps: lack of clear disability guidance, insufficient sick‑pay, and short‑term workplace counselling that fails neurodivergent staff.Why the Labour Market Is Failing Young PeopleThe stories echo the broader “Milburn report” warning that the labour market is increasingly inaccessible to young people, especially women and care‑leavers. Employers tout diversity initiatives, yet many lack the infrastructure to support disability accommodations or the mentorship needed for sustainable career progression.What Needs to Change to Re‑ignite Youth EmploymentGovernment‑mandated, clearer guidance on disability rights and employer obligations.Expanded financial safety nets for those unable to work due to health conditions.Long‑term, relationship‑based employment programmes that go beyond “first‑job placement”.Targeted investment in sectors that can absorb young talent, such as civil service apprenticeships and tech training pathways.

A Diplomatic Pivot: US and Iran Agree to 60-Day Truce Extension

US and Iran have agreed to a preliminary memorandum of understanding (MOU) to extend the ceasefire …
The Diplomatic Breakthrough in the GulfThe United States and Iran have reached a preliminary memorandum of understanding (MOU) to extend the ceasefire between the two nations for 60 days and commence negotiations for a permanent resolution to the conflict, according to officials. This framework, first reported by Axios and confirmed by the White House, represents a significant shift after weeks of stalled diplomacy and recent military skirmishes.The Framework of the Preliminary MOUThe agreement outlines specific terms for de-escalation, most notably regarding the Strait of Hormuz. The deal stipulates that vessel traffic will be "unrestricted" in the strategic waterway, and the US has agreed to lift its naval blockade on Iranian ports. However, the framework is not yet final; it requires the approval of President Donald Trump before implementation.Duration: 60-day extension of the current ceasefire.Status: Pending final approval from President Trump.Key Terms: Unrestricted vessel traffic in the Strait of Hormuz and lifting the US naval blockade.Context: Follows sporadic attacks and threats of sanctions against Oman.Resolving the Strait of Hormuz StandoffThe resolution of the Hormuz crisis is a critical economic and strategic development. Iran has long claimed sovereignty over the strait, insisting it must be managed jointly with Oman. Conversely, the US has vehemently rejected any form of Iranian control, including tolling systems. The agreement to allow unrestricted traffic removes a major source of geopolitical tension that threatened to disrupt global energy supplies.Beyond the Waterway: The Nuclear and Regional Sticking PointsWhile the Hormuz issue appears resolved, other complex challenges remain. The MOU reportedly requires Iran to commit to not pursuing a nuclear weapon, though Tehran has reiterated this stance publicly. The core disagreement lies in the US demand to dismantle Iran's entire nuclear program versus Iran's insistence on its right to enrich uranium domestically under the NPT.Furthermore, the broader regional conflict involving Hezbollah and Israel in Lebanon complicates the peace process. Iran has insisted that any truce must include Lebanon, where Israel has intensified attacks and issued displacement orders. The US has previously stated that Lebanon was not part of the April truce, creating a potential fracture in the diplomatic path forward.The 60-Day Countdown: What Comes Next?The next 60 days will be a critical test for regional stability. If President Trump approves the MOU, it establishes a clear timeline for negotiations. However, the success of this extension depends on resolving the lingering issues of US sanctions, Iran's missile production, and the ongoing war in Lebanon. Failure to address these points could lead to the unraveling of the truce and renewed hostilities.

National Mission Needed to Tackle UK Youth Unemployment, Says Milburn Report

A new commission led by former health secretary Alan Milburn warns that more than 1 million 16‑24‑y…
The Guardian editorial argues that the UK must treat the plight of NEETs as a national priority, linking rising youth unemployment to inadequate training, housing costs and a fragmented policy framework.Milburn Commission Highlights Over 1 Million UK NEETsThe commission’s report, due in the autumn, shines a bright light on the 1 million young people aged 16‑24 who are not in education, employment or training. It criticises political attacks on welfare and “kids‑these‑days” rhetoric, insisting that the problem is fundamentally a policy failure.The Scale of the Crisis: Over 1 Million Young People Out of Work or Study1 million NEETs – roughly one in eight of the 16‑24 cohort.60 % are economically inactive, meaning they are not actively seeking work.Health‑related universal credit claims have risen in regions with fewer entry‑level jobs.Apprenticeship starts have fallen 35 % over the past decade.Why the UK Is Falling Behind Europe on Youth EmploymentCompared with other wealthy European nations, the UK records one of the highest rates of young people not in work or study. Contributing factors include:Housing inflation limiting independent living for young adults.Restrictive GCSE combinations that disadvantage less academic pupils.Chaotic further‑education reforms and the poorly‑implemented apprenticeship levy.Automation and AI‑driven profit growth that do not translate into entry‑level opportunities.A National Participation System: Pathway to Re‑engaging Young WorkersThe report proposes a new “participation system” that would coordinate work and pensions, health, education and business departments to pull young people into the labour market. While ambitious, the editorial stresses that without a clear, cross‑departmental mission the UK will continue to lose a generation to inactivity.

Arsenal Owners Commit to Squad Evolution Even After Potential Champions League Triumph

Arsenal co-chairman Josh Kroenke has confirmed that the club will continue to aggressively invest i…
The Evolution Mandate: Arsenal's Post-Trophy StrategyDespite the immense pressure and excitement surrounding Arsenal's potential to secure a historic double against Paris Saint-Germain on Saturday, the club's ownership has signaled that success will not result in complacency. Josh Kroenke, speaking ahead of the final, emphasized that winning the Champions League would not alter the club's trajectory. He argued that in the high-stakes environment of modern football, standing still is equivalent to moving backward, and the club is committed to evolving to stay ahead of rivals.Financial Commitment: Beyond the £250m SummerThe Kroenke family has demonstrated a willingness to spend significantly to achieve their goals. Since Mikel Arteta's appointment, the club has invested almost £1bn in transfer fees. This summer alone saw a record-breaking outlay of more than £250m to secure the Premier League title after a 22-year drought. Kroenke noted that this spending was driven by the realization that teams around them are constantly improving, and Arsenal must match that intensity to remain competitive.Transfer History: Almost £1bn spent since Arteta's arrival.Summer 2026: Over £250m invested to win the Premier League.Ownership Transition: KSE took full control in 2018 after buying out Usmanov for £600m.The Arteta Factor: Securing the Managerial VisionA central pillar of Arsenal's future strategy is the retention of manager Mikel Arteta. With his contract expiring at the end of the next season, Kroenke explicitly stated that keeping Arteta is an “utmost priority.” He credited Arteta with “reinventing” the club’s culture since replacing Unai Emery, describing the manager as an “Arsenal man through and through.” The owners believe that the cultural shift initiated under Arteta is the foundation upon which their continued success will be built.Stadium Renaissance and Fan ExperienceInvestment is not limited to the playing squad. The owners have announced plans to renovate the Emirates Stadium, a project led by chief executive Richard Garlick. Kroenke expressed a desire to bring back the character of the ground while elevating the matchday experience for supporters. Drawing on the standards set by their sports empire in the United States, the Kroenkes aim to modernize the facilities to ensure the Emirates remains a world-class venue.Future Outlook: Sustaining Dominance in a Competitive LeagueThe message from the board is clear: the journey to the top is a marathon, not a sprint. Kroenke reflected on a pivotal moment in 2019—a 4-1 defeat to Chelsea in the Europa League final in Baku—which prompted a strategic pivot. As Arsenal prepares for life as a two-time major trophy winner, the prediction is that they will enter the next transfer window as one of the most dangerous teams in Europe, with the financial muscle and managerial stability to sustain their challenge for years to come.

Sinner's French Dream Shatters as Cerundolo Stages Stunning Comeback

Top seed Jannik Sinner suffered a shocking second-round exit at the French Open as unseeded Argenti…
The Shocking Exit at Roland GarrosJannik Sinner's bid for a maiden French Open title and career Grand Slam went up in smoke as he experienced physical issues in his second-round match against Juan Manuel Cerundolo and fell to a 3-6 2-6 7-5 6-1 6-1 defeat. The 24-year-old Italian arrived in Paris as the clear favorite for the title, having lifted claycourt titles in Monte Carlo, Madrid and Rome, with his main rival and defending champion Carlos Alcaraz ruled out with injury and Novak Djokovic searching for his best form.The Dramatic Turn of EventsBut Cerundolo tore up the script in a dramatic clash on a scorching Thursday where he held his nerve even as last year's runner-up Sinner crumbled while on the verge of a big win, sending shockwaves through Roland Garros. As the temperature climbed over the 30 degrees Celsius (86F) mark for the first time in the afternoon, Sinner had already breezed through the first set on the back of a solitary break, and looked to be in cruise mode.The Physical Toll of the MatchCerundolo offered resistance towards the end of the second set, but the 56th-ranked Argentinian was left with a mountain to climb after Sinner unleashed a huge forehand winner to double his lead in the match for the loss of only five games. The four-time Grand Slam champion cooled off with an ice towel in the break and turned up the intensity on his unseeded opponent in the third set to go 5-1 ahead, before he began to struggle and halted play when serving at 5-4.The Comeback VictorySinner returned from an off-court medical timeout five minutes later and was immediately broken for 5-5, and dropped the next two games to hand the set to his opponent, who sensed the chance to pull off a major upset. Still not at his best, Sinner surrendered the fourth set tamely and was broken early in the decider, as Cerundolo took full advantage to leave the Grand Slam without its title favorite.The Tournament AftermathSinner's unexpected exit creates a wide-open draw at Roland Garros, with the top half of the men's bracket now lacking a clear favorite. The Italian's physical concerns may also raise questions about his preparation for the upcoming grass court season, including Wimbledon. For Cerundolo, the victory represents the biggest win of his career and establishes him as a dangerous floater in the tournament, with the confidence to challenge remaining players.

RSI is the new AGI — and it's just as hard to pin down

Recursive self-improvement (RSI) has become the latest buzzword in AI, with researchers and startup…
The Rise of Recursive Self-Improvement in AIThe word "recursion" is the latest buzzword in AI circles. Two separate startups have taken on the name, and many more have started referencing recursive self-improvement (RSI) in their roadmaps. Like AGI before it, RSI has become a three-letter byword for a cataclysmic AI takeoff – even if there's still a little disagreement about what it exactly means.In basic terms, RSI refers to an AI system that can continuously upgrade itself. Once AI systems can manage the upgrade cycle better than humans, the process can become a closed loop, limited only by the compute power they can access, and humans are no longer necessary or even helpful.Scary or not, that's a vision that a lot of AI labs are eager to chase.Key Players Pursuing Recursive SystemsEarlier this month, well-known AI researcher Richard Socher launched the aptly named Recursive Superintelligence with RSI as an explicit goal. "Our main focus is to build truly recursive, self-improving superintelligence at scale," Socher told TechCrunch at launch, "which means that the entire process of ideation, implementation, and validation of research ideas would be automatic."A number of other prominent researchers are already chasing that same goal, hoping for a breakthrough that will make recursive self-improvement possible.One of the most prominent is Andrej Karpathy, a legendary figure from Tesla and OpenAI, who is using agent swarms to train LLMs on simple tasks for a project he calls Auto-Research. Karpathy has been unusually open about the project, tweeting about milestones regularly and making the building blocks available through a public GitHub repo. So far, the work has mostly been confined to making minor improvements on a GPT-2 scale model — as Karpathy noted in March, "It's not novel, ground-breaking 'research' (yet)" — but it's been enough to convince lots of other researchers to follow the RSI dream. And with Karpathy now working on pre-training at Anthropic, he will have plenty of opportunity to apply the idea at a larger scale.Adaption — founded by Cohere and Google alum Sara Hooker — recently launched a similar tool called AutoScientist in an effort to automate frontier training. Like Karpathy's auto-researchers, the system trains agents to make incremental improvements — but for Adaption, the goal is to make it easier to train a full-scale frontier model. If those same researchers start to push the frontier forward, the system could quickly spiral into something very much like RSI.Disarray founder Doris Xin drew more specific RSI interest when her self-trained machine learning agent took home 28 medals in a recent Kaggle competition, beating out many human-trained agents. As she sees it, the major challenge is reliability."I would argue, given infinite compute and infinite time horizon, we are already there," Xin told me. "I want to make an argument that this is not a creative endeavor, really. It's just a lot of meat-and-potatoes engineering."The Current State of Self-Improving AIThere's also plenty of evidence that the AI industry isn't very close to recursive systems in any meaningful way — and is still grappling with talking to a wary public about its progress. So Google CEO Sundar Pichai basically admitted in a recent podcast interview."It's a continuum, and we are all definitely making progress," Pichai said. "But in the way people describe RSI, that would represent a next level of acceleration and would have a lot of implications, but we aren't quite there yet."But the continuum includes an awful lot of self-improving AI systems.In January, one of Anthropic's lead programmers for Claude Code estimated that "close to 100%" of his team's code was written by the tool — a frank admission that Claude Code was literally writing itself.Just because engineers are using an AI tool doesn't mean the tool can replace them — but Anthropic seems to be getting close to replacing engineers too. In a recent survey tied to the Mythos preview, five out of 18 Anthropic engineers believed that, with harness improvements, this version of Mythos could soon substitute for an L4 engineer — a midlevel programmer who can take on involved projects without supervision.Still, there were some of the same weaknesses you might expect."Some of Claude's major reported weaknesses compared to an L4 include: self-managing week-long ambiguous tasks, understanding org priorities, taste, verification, instruction-following, and epistemics," the report reads.In other words, its weaknesses are everything involved with self-direction, which is the cornerstone for RSI. But sure, for everything else, Claude is ready to step right in.Expert Perspectives on RSI TimelinesJust like the AGI term before it, the AI industry also can't tell us how far away it is from showcasing a meaningful recursive system. When Georgetown's Center for Security and Emerging Technology assembled a group of experts to study RSI last year, the group found a major split in assessments — some expecting an imminent "superintelligence" style explosion while others expected slower progress and an eventual plateau. But all agreed that recursion made the future especially difficult to predict.Helen Toner, director of CSET and a former board member at OpenAI, told TechCrunch that simply using AI tools to do AI research isn't enough to qualify as RSI. "They're just using AI for as much as they can," Toner told TechCrunch. "And I think that is different from the classic definition of RSI, which is really that there are no humans needed."Toner pointed to a recent post by METR's Ajeya Cotra, which distinguishes different milestones on the path to the AI research takeover. One step, which Cotra calls "adequacy," would come when the system can still perform research after all humans are removed — even if the resulting research isn't as valuable or efficient. "Parity" comes when an AI-only system is as good at research as a human-only system. "Supremacy," the final stage, comes when an AI-only system outperforms a collaborative system between humans and AI.Ultimately, Cotra concludes that AI is very close to the adequacy threshold of being able to produce some work on its own — similar to the incremental changes made by Karpathy's Auto-Research system. "I wouldn't be totally shocked if you told me this milestone had already passed, and I expect it to happen in the next couple years," Cotra wrote.She was less clear on when parity will come, but once it does, she thinks it would "massively accelerate the pace of AI progress, leading to AI research supremacy within another year."The Challenges Ahead for Recursive AIWith so much of AI built on scaling laws, there's a strong tendency to think RSI will follow the same curve. Toner thinks that many of those pursuing AI research and development via RSI "think of it as a pretty smooth ladder, where you can just keep scaling up."But even if AI researchers are able to make incremental improvements like Karpathy's auto-researchers, there will be larger challenges in handing off the whole process of research. Toner put it in terms of the history of computing, which has seen human beings handing off more and more of the process while still directing things from the top."We went from machine languages to assembly language and compiled languages; you're getting further and further from the guts of the computer," Toner said. "But the human is still, in some intuitive sense, running the show."Moving beyond that paradigm will take significant challenges, both in engineering and alignment. But even with the massive investments happening, there's no infinite compute available — and the basic trade-off between human labor and machine intelligence will be hard to overcome.The Future of Recursive Self-ImprovementAs for a total recursive AI system of apocalyptic visions? The only thing researchers essentially agree on is that, like AGI, it's not here yet.

Anti-Immigrant Anger Swells in South Africa as Migrants Are Forced onto Streets

Anti‑immigrant sentiment is intensifying across South Africa after local authorities began clearing…
Anti‑immigrant anger is reaching a new peak in South Africa as municipal officials ordered the removal of makeshift camps that housed thousands of migrants, leaving them exposed on public streets. The move has ignited protests, a surge in xenophobic incidents, and a heated debate over the nation’s immigration policy. Escalating Xenophobic Tensions After Forced Evictions City councils in Johannesburg and surrounding townships issued eviction notices this week, citing health and safety concerns. Residents of the cleared camps report being given less than 24 hours to vacate, with many forced to sleep on sidewalks or in overcrowded shelters. Evictions began on 2026-05-25 across three major informal settlements. Local NGOs estimate that over 5,000 migrants were displaced. Community leaders claim the actions were taken without adequate consultation. Limited Data Highlights a Growing Crisis Official statistics on the displacement are scarce, but available reports point to a sharp rise in xenophobic activity: The South African Police Service logged a noticeable uptick in hate‑crime complaints in the past month. Human‑rights groups note an increase in verbal and physical attacks targeting foreign nationals. Economic analysts warn that prolonged unrest could deter foreign investment. Political Fallout and Social Cohesion at Risk The government’s response has split opinion. While some politicians defend the evictions as necessary for public order, opposition parties and civil‑society groups accuse the administration of stoking xenophobia. President Cyril Ramaphosa called for “orderly migration management” but avoided direct criticism of local authorities. Opposition leader John Steenhuisen demanded an immediate halt to evictions and a review of immigration policy. International bodies, including the UN, have urged South Africa to uphold the rights of migrants. Potential Policy Shifts and International Scrutiny Analysts predict that sustained pressure could force the government to adopt a more coordinated approach: Implementation of a national framework for temporary housing of displaced migrants. Increased funding for community‑integration programs to mitigate xenophobic sentiment. Possible sanctions or aid reductions from foreign partners if human‑rights violations continue. Until concrete measures are taken, the risk of further unrest remains high, and South Africa’s reputation as a regional hub for trade and tourism could suffer.
