Three people have died after a suspected outbreak of hantavirus on a cruise ship in the middle of the Atlantic ocean. At least one other passenger is in intensive care in South Africa.

The World Health Organization announced the deaths in a social media statement on Monday, along with one confirmed case of the rare disease. Authorities are investigating another five suspected cases among passengers travelling on the MV Hondius.

So, what is hantavirus? And why can it be so deadly?

As the investigation unfolds, here’s what we know.

What is hantavirus?

Hantavirus is a rare but severe respiratory illness that can cause severe bleeding, fever and even death.

The virus is spread by rodents, such as mice and rats, mainly through the urine and droppings of infected animals.

Hantavirus does not typically spread from person to person. However, in rare cases it may spread between people.

Globally, there are an estimated 150,000 to 200,000 cases of hantavirus each year.

It is less contagious than airborne viruses such as COVID and influenza, as it typically does not spread from person to person.

What makes it so deadly?

There are two main types of hantavirus, each with different symptoms.

Hantavirus pulmonary syndrome, which affects the lungs, is mainly found in the United States. If a person becomes infected with this type of hantavirus, within days they will likely experience coughing and shortness of breath.

As the illness progresses, they can develop symptoms such as fatigue, fever and muscle aches. They may also get headaches, dizziness, nausea, vomiting and abdominal pain. This is the most deadly kind of hantavirus. Tragically, about 38% of people who develop these symptoms die from the disease.

Hemorrhagic fever with renal syndrome is mainly found in Europe and Asia, but the strain known as the Seoul virus has spread around the world. This form of hantavirus mainly affects the kidneys.

People usually develop symptoms within two weeks of being exposed to this virus. Early symptoms include severe headaches, abdominal pain, nausea and blurred vision. More advanced symptoms include low blood pressure, internal bleeding and even acute kidney failure. This disease can be caused by different viruses and some are more deadly than others, meaning between 1% and 15% of cases can be fatal.

Unfortunately, there is no specific treatment or cure for either type of hantavirus. However, early medical treatment may increase a person’s chance of survival. This can include using respirators, oxygen therapy and dialysis.

Authorities are still investigating which type of hantavirus the passengers were exposed to.

How did it get on a cruise ship?

In a closed environment such as a cruise ship, there are two possible ways passengers could have contracted hantavirus.

One is being exposed to the virus while on a shore excursion.

The other possibility is that rodents may have entered the ship on cargo, and then spread the disease to passengers through their infected urine or droppings. Other factors such as hygiene standards and food storage practices may have caused the infection to spread more quickly.

How do viruses mutate and jump species? And why are ‘spillovers’ becoming more common?

To contain this suspected outbreak, authorities must first ensure any rodents are safely contained and removed from the ship. They should then monitor all passengers for hantavirus symptoms. The virus is diagnosed with a PCR test, similar to those used to diagnose viruses such as COVID.

Given there is no specific treatment for the disease, authorities must help any infected passengers manage their symptoms. This involves checking that they are breathing normally and their kidneys are functioning properly.

So, how worried should we be?

Although alarming, cases of hantavirus remain are extremely rare. But it can look similar to other respiratory illness, so you should always get symptoms checked. If you’ve been in regions where the virus is found and experience shortness of breath, fever or any other flu-like symptoms, see your GP.

As social media becomes a central part of young people’s lives, concerns are growing about its impact on their mental health. Yet public debates and measures tend to treat adolescents as one homogeneous group. We frequently ignore the fact that social media use does not affect all young people in the same way – nor does it have the same impacts on their wellbeing.

In a recent chapter of the World Happiness Report 2026, published by the UN Sustainable Development Solutions Network in partnership with the University of Oxford, we have examined how problematic social media use relates to the wellbeing of adolescents from different socioeconomic backgrounds.

We looked at 43 countries spanning six broad regions – Anglo-Celtic, Caucasus-Black Sea, Central-Eastern Europe, Mediterranean, Nordic, and Western Europe – covering mainly European countries and their immediate neighbouring areas.

Using data from over 330,000 young people, we found a clear and consistent pattern: higher levels of problematic social media use – that is, compulsive or uncontrolled engagement with social media – are associated with poorer wellbeing.

Teenagers who report more problematic use tend to experience more psychological complaints, such as feeling low, nervous, irritable, or having difficulty sleeping. They also have lower life satisfaction, a measure of how positively they evaluate their lives as a whole.

This pattern appears across all countries in our study, but its strength varies from one country to another. It is particularly pronounced in Anglo-Celtic countries such as the UK and Ireland, while it is comparatively weaker in the Caucasus-Black Sea region.

Socioeconomic background matters

The story does not end with geography. Globally, teenagers from less advantaged backgrounds tend to be more vulnerable to the negative consequences of problematic social media use than their more advantaged peers.

This means socioeconomic status – the material and social resources available to a household, such as income and living conditions – actively shapes the risks and opportunities that young people experience as a result of online environments.

Interestingly, these inequalities are especially visible when we look at life satisfaction. Differences between socioeconomic groups are smaller when it comes to psychological complaints, but much clearer and more consistent for how adolescents evaluate their lives overall.

One likely reason is that life satisfaction is more sensitive to social comparisons. Social media exposes young people to constant benchmarks – what others have, do, and achieve – which can amplify differences in perceived opportunities and resources.

At the same time, these patterns are not identical everywhere. For instance, socioeconomic differences in psychological complaints tend to be modest in most regions including continental European countries such as France, Austria or Belgium, but are more clearly observed in Anglo-Celtic countries such as Scotland and Wales.

In contrast, socioeconomic gaps in life satisfaction appear across most regions, although they tend to be weaker in Mediterranean countries such as Italy, Cyprus and Greece.

A growing problem

We also examined how these patterns have evolved over time. Between 2018 and 2022, the link between problematic social media use and poor adolescent wellbeing became stronger.

This suggests that the risks linked to problematic use may have intensified in recent years, possibly reflecting the growing role of digital technologies in young people’s daily lives, particularly during and after the Covid-19 pandemic.

Importantly, this intensification has affected teenagers across socioeconomic groups in broadly similar ways in most regions. In other words, while inequalities remain they have not widened over this period.

No one-size-fits-all solution

While public debates about social media and mental health often treat adolescents as a single demographic group, our results show a more complex reality. Problematic social media use is linked to poorer wellbeing across countries, but its effects are shaped by social realities. They vary depending on where young people live and what resources are available to them.

Not all teenagers experience the digital world in the same way, and not all are equally equipped to cope with its pressures. Recognising this is essential for designing policies that are not only effective, but also equitable, ensuring that interventions reach those adolescents who are most vulnerable to digital risks.

Arsenal is still on the top of the English Premier League ladder, but as in previous years, the Gunners might be crumbling just when a first title since 2003–04 is within touching distance.

In early April, Arsenal had a commanding grip on the title – nine points ahead of nearest rivals Manchester City. Now it’s just three (and City has played one less game).

This isn’t the first time Arsenal has lapsed at late stages in recent years: last season they finished second behind Liverpool. In 2023–4 they finished runners-up behind Manchester City. They were second again the year before.

Arsenal fans are no doubt expecting another dose of late-season heartbreak – it’s likely players and club staff are feeling similarly jittery. However, there are psychological strategies that could help them keep fighting until the final whistle.

Oh no, not again

The team led by Mikel Arteta recently eked out a 1-0 win against Newcastle United but before that had suffered two consecutive defeats: first against Bournemouth at home and then to Manchester City.

Looking closely at these two matches, they had a similar dynamic: Arsenal conceded the first goal in the first half, scored the equaliser a few minutes later, and suffered defeat in the second half.

This looks like a symptom. If you concede a goal earlier in a match, you need to put extra energy in to find an equaliser. At halftime, players should reset but the emotional cost of chasing an equaliser may impair their shift into a winning mindset.

This is choking under pressure: when fear of losing is bigger than the willingness to win.

Arsenal’s players have a team of sport psychologists and mindset coaches at their disposal.

Here are the four key psychological tools they will probably use to improve consistency in these final rounds of the season.

1. Work out your routines

Consistency is crucial for athletes, and predictability creates the space for players to become consistent.

The basic assumption behind the concept is: if you keep doing the same things, you can expect the same results. Regardless of the level of competitive pressure, sport performance tends to become more stable when pre-performance routines are applied.

These routines can take many forms: some athletes might prefer to take a shower, or pray, visualise or meditate before a match.

During games, many prefer to take a deep breath before a penalty (such as Cristiano Ronaldo) whereas others might fix their gaze on a single spot on the ball before shooting.

The key is, sport psychologists should help athletes tailor their pre-game or pre-shot routines to enhance performance.

2. Practise mindfulness

Mental distress can have a crushing impact on athletes.

When an athlete is emotionally stressed, the body tends to increase its levels of cortisol (the stress hormone), which leads to muscle rigidness. This can impact performance.

To counter this, leading stress education expert Jon Kabat-Zinn developed mindfulness-based stress reduction – a set of techniques that includes breathing meditation, deliberate focus on the present moment, and yoga-like body movements to improve emotional regulation.

When empirically tested in athletes, mindfulness meditation showed significant effectiveness to improve attentional control (the ability to focus attention on a task while avoiding distractions).

Applying mindfulness techniques alone or in combination can boost performance and may help Arsenal achieve the consistency needed in these final rounds.

3. Be positive with self-talk

Self-confidence and fear of mistakes can freeze athletes in high-stakes moments. This impacts decision-making and slows down execution.

For example, a full-back gets the ball on the defensive flank and scans for options. He can either play a penetrating pass to break the opposition’s defensive lines or pass backwards to his centre-back.

This a split-second decision – if he hesitates, the forward pass can be intercepted and the backward pass may come under pressure, leading to a costly mistake.

To tackle self-doubt, sport psychologists teach athletes to reframe their thoughts and create more effective task-oriented inner dialogues.

Research shows instructional self-talk can help athletes improve their performance.

So in the example above, what our full-back needs to do is, instead of thinking about the potential consequences of his actions, just tell himself to execute the pass.

If done properly, instructional self-talk can help Arsenal’s players choose the best options and execute them.

4. Get used to dealing with pressure

Matches are high-stakes, but training sessions tend to be focused on technical and tactical skills under lower pressure.

However, research shows embedding mild anxiety into training sessions helps athletes cope better under pressure.

Athletes who train under pressure often perform better than those who do not.

So Arsenal’s coaches should be looking to ramp up pressure in training sessions while ensuring the players can work with sport psychologists and mindset coaches.

A race in two

After the recent win against Newcastle, Arteta said:

I don’t expect after 22 years not winning it that it is going to be a path of roses and beautiful music around it. It is going to be like this and we are ready for it.

Whether they are ready for it remains to be seen. But if the Gunners are to finally taste the ultimate success in this season’s Premier League, a combination of these techniques might help them cope under pressure, avoid choking, and finally lift the trophy.

Assuming, of course, Manchester City allows it.

On May 31st, Colombian voters will go to the polls with Abelardo de la Espriella – criminal lawyer, self-styled outsider, and self-described “Tiger” – securing his place in the runoff against left-wing Iván Cepeda. In Brazil, Senator Flávio Bolsonaro – the son of incarcerated former President Jair Bolsonaro – is also busy, touring Washington, Dallas, and El Salvador, burnishing a “Bolsonaro 2.0” brand ahead of October elections.

The two men have never appeared on the same stage, but they are running similar campaigns, reading from similar scripts, and looking toward the same set of foreign role models. In a familiar recipe, their platforms combine free-market economics, conservative values, and a tough approach to crime.

De la Espriella proposes reducing the size of the state by up to 40%, eliminating hundreds of thousands of public contracts and positions, and slashing taxes. He considers himself a major political admirer of Argentina’s President Javier Milei, someone who, in his eyes, has charted the solution to the hemisphere’s economic problems.

Flávio Bolsonaro has presented his pre-candidacy as a direct continuation of the legacy of his father, who was arrested last year for attempting a coup d’état following his defeat in the 2022 elections. Bolsonaro’s oldest son describes his project as the return to a market-oriented, Pro-Washington, and nationalistic platform.

Economy, security, and foreign policy

Although the language varies at times, the ideology that drives both campaigns does not. Both Bolsonaro’s son and De la Espriella embrace a combination of right-wing conservative security stances and the same neoliberal economic doctrine that was tried across Latin America in the 1980s and 1990s, showcasing a repacking of old views to try and solve old problems.

On security, both candidates have vowed to follow the steps of El Savador’s strongman president Nayib Bukele. Flávio Bolsonaro, after visiting El Salvador’s notorious CECOT mega-prison in person, called Bukele’s approach a “radical transformation” and demanded the construction of “many, many prisons” in Brazil to address a deficit he estimates at 500,000 beds.

De la Espriella is even more explicit: “Against the narcoterrorism that Petro has coddled, an iron fist like Bukele’s,” he has declared, promising to bomb guerrilla encampments and build high-security mega-prisons modeled on El Salvador’s CECOT. He also proposes a new prison corps staffed by military reservists and veterans, administered privately, removing the current penal institute which he describes as “a cancer for Colombia.”

On foreign policy, De la Espriella has declared that any relationship Colombia has with Venezuela must be conducted “through the United States”, essentially ignoring the Venezuelan Government. This is a remarkable formulation that would break tradition with previous Colombian foreign policy towards Caracas, which was marked by acting mostly in an independent fashion of its allies in the region. He wants to strengthen the military alliance with Washington and Tel Aviv, and has called on the Trump Administration to prosecute and extradite incumbent President Gustavo Petro over supposed drug charges.

Flávio Bolsonaro, meanwhile, appeared at CPAC in Dallas, supporting the alliance with President Trump. He openly positioned Brazil as a bulwark in Washington’s geopolitical strategy to reduce Chinese influence in the hemisphere and offered up his country’s strategic resources to this end. Trump’s own political adviser, Jason Miller, declared Flávio the “next president” of Brazil from the conference stage.

What is striking about all of this is not just the content of these proposals but their explicitly transnational character. As they aim for the Presidency, De la Espriella and Flávio Bolsonaro are aiming for membership in a global conservative movement, constructing their political identities by association with leaders like Trump, Bukele, and Milei.

How far can their promises go?

This transnational strategy, however, has already shown some limits. When Eduardo Bolsonaro lobbied Washington to impose tariffs and sanctions on Brazil’s government and economy, 57% of Brazilians disapproved of what he was doing to their country. Instead of strengthening the Bolsonaro brand, this episode handed left-wing president Lula Da Silva a nationalist narrative that the right had monopolized for years. All while presidents Lula and Trump would go on to partially reconcile not that long after.

“Bukelizing” security can also be problematic. Importing the Salvadoran model to much bigger countries, whose public security issues are complex and widespread, would be an invitation to the kind of arbitrary State power that Colombian and Brazilian democracies spent decades trying to contain. By tapping into Bukele’s youthful appeal and increasing popularity, Bolsonaro and De la Espriella vow to promote potentially authoritarian solutions under a veil of efficiency.

There is a real frustration at the root of these candidacies, and it would be a mistake to dismiss it. Colombia and Brazil are countries where insecurity is existential for millions of people, where inequality persists despite decades of formal progress, where institutional corruption has eroded confidence in the political class.

Even though De la Espriella and Flávio Bolsonaro are tapping into genuine concerns, the solutions they offer are not new responses to old problems. Economic shock therapy in largely unequal societies, militarized crackdowns in countries with a long history of institutional violence, and a lack of inherent agency in terms of foreign policy are just old responses to old problems. This time, retooled with new aesthetics and a new international support network.

As the closure of the Strait of Hormuz drags on, the United Nations’ International Maritime Organization has sounded the alarm over a related humanitarian crisis: the plight of the crew stuck on ships at or near the strait.

Up to 20,000 seafarers on 2,000 vessels remain stranded in and around the strait, enduring a combination of physical danger and psychological stress typical of combat zones.

They face daily horrors at work. Exhausted by the risk of being hit by missiles or falling debris, they cannot rest in safe harbours, as nearby ports are not secure.

As their supplies dwindle to dangerously low levels, they must ration food and water and rely on charities such as Mission to Seafarers for supplies (at great risk to the charity workers).

The longer the crisis persists, the more likely seafarers will be working after their contracts expire. They risk not being paid and being unable to get home. Desperate seafarers have also reportedly been targeted by scammers offering safe passage through the strait in exchange for cryptocurrency.

The current crisis is deeply troubling. But the grim reality is that even at the best of times, seafarers generally experience appalling working conditions, while contending with geopolitical crises and unpredictable trade cycles.

These workers face financial insecurity, job uncertainty, physical and mental hazards, isolation, overwork and limited career prospects. Fatigue and sleep deprivation expose them to serious injuries or illnesses on vessels that often operate without adequate medical facilities or qualified doctors.

Lessons of COVID

The current crisis echoes problems revealed during the COVID pandemic. Then, some 400,000 seafarers were stranded at sea. Many were unpaid, and couldn’t be repatriated.

Some ship operators introduced “no crew change” clauses (which ban crew changes while the operator’s cargo is onboard). Such clauses in contracts undermine seafarers’ rights under the Maritime Labour Convention 2006. This exists to promote safety, security and good working conditions on ships, and protect seafarers’ rights.

As a result of an amendment to this convention, seafarers have since been designated as “key workers”. This facilitates access to shore leave, repatriation, crew changes and medical care ashore.

However, the amendments do not take effect until December 2027.

More broadly, the Maritime Labour Convention requires shipowners to provide accommodation, food, transportation, cover for medical expenses and repatriation (the cost of the seafarers’ journeys home, including accommodation).

But it relies on the countries where ships are registered (known as flag states) to regulate shipping – and ships are constantly moving and beyond the reach of regulators. Many are registered under flags of convenience (that is, not where they are owned) in countries with low labour standards that are seldom enforced.

Risk of attack or abandonment

Many commercial ships currently stuck in the Strait of Hormuz have been targeted in military operations, by both Iranian and US forces.

Seafarers also face the unique threat of abandonment. This is where shipowners – in breach of maritime law – leave them without wages, support or maintenance. This occurs when shipowners fail to secure new business.

And it is very difficult for seafarers to leave the ship on which they work. Maritime law also compels crews to keep ships safe and operational and prevents them abandoning ships except under the most extreme circumstances, such as if the vessel is sinking.

In 2025, 6,223 seafarers were abandoned on 410 ships – the sixth yearly increase in a row.

According to the International Seafarers’ Welfare and Assistance Network, there are probably many more unreported cases as seafarers fear dismissal and being blacklisted from other work.

Early indications for 2026 are that the number of seafarers abandoned by shipowners already exceeds 6,000 cases.

Abandoned seafarers were also owed US$25.8 million in unpaid wages in 2025, of which just $16.5 million was recovered.

Shadow fleets

Most abandonments are linked to the shadow fleet, meaning ships that carry oil, gas and other goods in breach of sanctions. The shadow fleet has expanded to 20% of the world’s tankers and 7.5% of LPG carriers.

Shadow fleet vessels have opaque ownership, inadequate insurance and poorly trained crew obtained through illegal recruitment methods bordering on human trafficking.

They are registered in countries with lenient labour laws and poor labour protections, few safety regulations and little oversight. More than half of these ships are more than 15 years old (the traditional cut off age for tankers used by major oil companies) and are in substandard condition. They also use ports where they are unlikely to be inspected.

In addition, they are often run by small ship management companies with little technical knowledge or industry experience, about which very little information is available.

Stranded in the strait

Under the circumstances in the strait, seafarers have been denied the right of repatriation. First, the US blockade prevents ships accessing ports from which they could transit. Second, the fuel crisis has driven the price of flights to a level that many shipowners cannot afford.

India, which maintains diplomatic relations with Iran and imports 90% of its gas from the Persian Gulf, has negotiated the safe passage of its seafarers.

But thousands of others remain stranded, with no states coming to their aid.

Two months after the United States, along with Israel, launched a war against Iran, that conflict appears far from a lasting resolution.

Much commentary on the protracted nature of the conflict has centered on the limits of both the military and diplomatic approaches to the war. But the conflict has also exposed another key reality: the limits of U.S. sanctions.

The U.S. has been the world’s preeminent economic and military power for decades, certainly since the end of the Cold War. It is at the center of much global financial activity and has a military budget well beyond China, the closest competitor.

Leveraging that power, the U.S. has long used economic coercion to achieve its foreign policy goals, whether against North Korea under the Kim regime, Russia over its invasion of Ukraine or Iran since the 1979 revolution that overthrew the U.S.-allied shah.

But as U.S. power in the world has slowly declined amid the rise of China and an increasingly multipolar world, the country has likewise lost some of its ability to effectively use economics as a weapon. Indeed, as scholars of economic sanctions and statecraft, we believe that the conflict against Iran has made clear the diminishing returns of U.S. economic sanctions.

The limits of sanctions on Iran

Since 1979, relations between Washington and Iran have been antagonistic. U.S. policy has been largely to punish, contain or isolate Iran, and successive administrations have done so in part through a mix of primary, secondary and targeted financial economic sanctions.

U.S. economic coercion has been applied on Iran for a variety of reasons, including its alleged state sponsorship of terrorism throughout the region and its nuclear program.

The emergence of that nuclear program in 2003, which later resulted in United Nations sanctions against Iran, saw U.S. and European Union interests around Iran converge.

This convergence led to the U.S. and EU cooperating on economic sanctions against Iran, which limited Iranian access to the European banking system. The combined coordinated efforts proved onerous for the Iranian economy, which, as political scientist Adam Tarock notes, meant Iran was “winning a little, losing a lot.”

The Joint Comprehensive Plan of Action (JCPOA), negotiated between the U.S., Iran, members of the EU, Russia and China in 2015, placed limits on Iran’s nuclear program in exchange for sanctions relief. At the time, the Iranian economy was suffering crushing inflation and rampant food prices. The agreement would provide relief from decades of economic punishment and the removal of EU, UN and U.S. economic sanctions.

However, the U.S. withdrew from the agreement in 2018 under the first Trump administration and later reimposed sanctions on Iran. The return of economic sanctions as part of the first Trump administration’s maximum pressure campaign – even if not supported by other nations – saw most global firms refrain from doing business with Iran out of risk aversion.

Additionally, despite the EU’s efforts to preserve the JCPOA, Iran restarted its nuclear enrichment program in 2019, one year after the U.S. withdrawal. The Biden administration’s subsequent expressed intention to reenter the deal never came to fruition.

Believing sanctions relief was not a realistic outcome after the agreement’s failure, Iran – though battered by losing access to the global financial system – has found increasingly creative workarounds. Those have included utilizing so-called shadow fleets shipping illicit Iranian goods, creating successful homemade military products like cheaply made drones and ramping up trade with partners outside the Western orbit.

Indeed, since the nuclear agreement’s collapse, Iran has pursued much closer ties with China and Russia at the expense of prior robust economic relations with Europe. As Iran reorients its trade and economic relations, the U.S. and the West have lost economic coercive leverage.

Separated from a diplomatic endgame, U.S. sanctions – and the current blockade of Iranian-linked ships – appear to be only hardening Iranian resolve. Even if a deal were reached to reopen the Strait of Hormuz, Iran has said it plans to push for commercial ships to pay a toll going forward – something that didn’t exist before the war.

In effect, Iran’s ongoing de facto closure of the strait has redirected U.S. economic coercion back at the Trump administration.

Blowback in the energy markets

The biggest costs of that ongoing closure for the U.S. has been in energy.

The U.S. today is one of the largest exporters of crude and refined petroleum globally, making it particularly exposed to oil price volatility. At the same time, some Americans see the development of fossil fuel resources as a key policy priority. As the U.S. becomes more embedded in the export energy sector, it is increasingly experiencing collateral damage – namely, higher oil and gasoline prices – when its foreign policy decisions disrupt oil-related trade.

One way that collateral damage manifests is the affordability problem for many Americans as gas prices rise, which is likely to also create political costs for the Trump administration.

While the U.S. has taken steps to ease the economic disruptions to American consumers by relaxing oil sanctions on Russia and Iran – thus undermining its own sanctions policy – these policy shifts have done little to nothing to offset rising fuel prices. They will likewise fail to ameliorate the potential for economic damage caused by the ongoing disruptions to commerce due to the Strait of Hormuz dangers and uncertainties.

Famed economist Albert O. Hirschman once noted that countries use their strategic position to shift others’ cost–benefit calculations, especially through trade disruptions. And for decades, the U.S. used its privileged position in the global financial system to pressure both rising countries and those not explicitly part of the U.S. alliance.

But as the U.S. becomes more exposed to the consequences of its own decisions, its ability to lead and coerce has stalled under costs it cannot easily absorb.

No longer leading by example

Historically, U.S. economic power was made possible not only by the country’s unilateral strengths but its willingness to pool resources and work multilaterally with other nations.

The Trump White House’s inability to put together a multinational coalition to address the political and economic challenges caused by U.S.-Israeli attacks on Iran is not surprising. But they further reflect the evaporation of goodwill the U.S. previously enjoyed with allies in and outside the region.

As the U.S. abandons a playbook that has buttressed its power for decades, Russia has grown bolder, China is edging ahead of the West and middle powers like Iran are able to hold out against American economic and military strength.

None of this means the U.S. no longer holds significant global power. But its turn toward a sanction-first, ask-questions-later approach has, we believe, eroded its ability to shape the behavior of other nations. And it has done so while imposing increasingly tangible costs on both American strategy and the well-being of its own citizens.

A humanoid robot recently made headlines around the world for running a half-marathon and beating the human world record. Around the same time, an AI-powered robot defeated an elite human player in table tennis. What the robot lacked in experience, it made up for by reacting faster and more consistently than any person could.

These moments feel like milestones. Finally, it seems machines are stepping into one of the most human arenas – sports.

But while it is tempting to frame this as robots versus humans, sport robotics isn’t really about competition. It’s about how machines can learn to move, react and interact in dynamic, unpredictable environments – and what that means for human performance.

How do you train a robot to play sport?

Training a robot to play sport is fundamentally different from training a human athlete.

People learn through practice, coaching and experience, constantly adjusting to changing conditions. In sport science, this is often described as a tight coupling between perception and action. That is, seeing, deciding, and moving in one continuous loop.

Robots, by contrast, are trained using a combination of simulation, data and control algorithms. Engineers build detailed virtual environments where robots can “practice” millions of times. They learn how to track objects, predict motion and coordinate their bodies. Sometimes, motion analysis techniques are used to track athletes doing the specific movements the robot needs to emulate.

For fast-paced sports such as table tennis, the challenge is extreme. A robot must detect the ball, predict its trajectory and execute a precise movement within fractions of a second. This requires close integration between computer vision, machine learning and real-time control.

One of the biggest advances in recent years has been the ability to train robots in simulation and then transfer those skills into the real world – a process known as “sim-to-real”. Combined with rapid improvements in sensors and computing, this has dramatically accelerated progress.

We’ve seen similar developments in robot basketball and robot soccer, where systems have evolved from simply locating the ball to coordinating as teams, making tactical decisions and adapting to opponents.

Beyond entertainment

While robot athletes make for compelling demonstrations, their greatest impact will likely be behind the scenes where they can be used to train human athletes.

One of the central challenges in sport is designing effective practice. Athletes need repetition to build skill. But they also need variability to reflect real competition. Too much repetition becomes predictable; too much variability becomes chaotic.

Robotics offers a potential way to balance both.

A robotic training partner can deliver highly repeatable actions at elite intensity, while also introducing carefully controlled variation. For example, a robotic tennis server could replicate the motion of a world-class player while systematically varying ball speed, flight and placement.

From a sport science perspective, this creates what is known as a “representative learning environment”. The key benefit is it replicates the key perceptual and decision-making demands of elite competition, which is difficult for coaches to recreate in the training environment.

In our work, we’ve been exploring how robotics could support sports such as tennis, cricket and the football codes. The goal is to combine realism, repeatability, variability, and data to enhance skill development and link technique to outcomes.

Robots may also help manage training load. They can reduce the physical demands on coaches and training partners while still exposing athletes to high-quality game-like scenarios.

Beyond performance, there are opportunities for fan engagement. Interactive robots at live events or demonstrations of elite skills could offer new ways for audiences to experience sport.

Will robots ever be ‘great’?

Over the next decade, robots will likely become more agile, more robust and better able to operate in complex environments. Tasks that robots currently find difficult, such as running on uneven terrain and catching or throwing balls, will become increasingly achievable.

But even as robots improve, there are important limits.

Sporting greatness is not just about executing movements perfectly. It involves creativity, decision-making under pressure, and the ability to adapt in ways shaped by experience, emotion and context.

From a sport science perspective, elite performance emerges from the interaction between the athlete, the task and the environment. Robots can be engineered to perform specific tasks extremely well, but they do not experience this interaction in the same embodied, meaningful way.

This means robots may surpass humans in tightly defined challenges – such as bowling a cricket ball with perfect consistency – but they are unlikely to achieve greatness in the holistic human sense.

A new role for robots in sport

Rather than replacing athletes, robots are more likely to become part of the sporting ecosystem.

In the same way that video analysis and wearable sensors have transformed training, robotics offers a new tool for coaches and sport scientists. It enables practice environments that can be precisely controlled, repeated, and adapted to individual needs.

The real opportunity is not to build robot champions, but to better understand human performance, and help athletes reach higher levels.

King Charles’s speech to the US Congress – only the second such address by a British monarch – demonstrates how much both the US and the UK have changed in the last three decades.

The first speech was in May 1991 during his mother, Queen Elizabeth II’s, third state visit to the US. The underlying purpose of both speeches was the same: to stress the enduring links between Britain and the US. But the circumstances in which they were delivered were very different.

The late queen’s speech came in the wake of joint action by US and British forces, along with other allies, to eject Saddam Hussein’s Iraqi troops from Kuwait. She referenced this in her speech as a concrete example of the strength of the Anglo-American alliance.

In 2026, the UK has pointedly refused to join the US-Israeli attack on Iran, angering President Donald Trump. Charles’s speech adroitly inverted the moral of this apparent diplomatic rift, suggesting that tensions in the past had always been overcome. Referring to the revolution of 1776 he noted: “Ours is a partnership born out of dispute, but no less strong for it”, because ultimately “our nations are in fact instinctively like-minded”.

A speech like this, voiced by the monarch, can serve at least two useful purposes. The first is to portray things that are, at heart, profoundly political, as being somehow above politics. The second is to place the transitory difficulties of day-to-day diplomacy within the much longer-term perspective of a dynasty that traces its lineage back to the Norman Conquest.

These two elements featured in how both Elizabeth II and Charles’s speeches depicted the Anglo-American alliance. The latter was the basis of a joke by the king, who referred to the actions of the Founding Fathers “250 years ago, or, as we say in the United Kingdom, just the other day”.

Charles’s speech was beautifully crafted and delivered with a degree of warmth and conviction that was always beyond the range of his mother’s public oratory. That, in itself, was almost an implicit reproach to the president’s own rambling, undisciplined public pronouncements.

And in more than one way the address was pitched over the head of Trump. The lack of any immediate pushback from the president suggests that the subtlety of some of the messaging eluded him. But in a more significant sense, it was an appeal to causes that still resonate with much of the American political class if not with the Trump administration itself.

Charles stressed the value of Nato and the importance of “the defence of Ukraine and her most courageous people”. He made a sly reference to his proud association with the Royal Navy – an institution that has been the subject of some disparagement by Trump in recent weeks.

He emphasised the importance of protecting the environment, although couched in a Trumpian language of profit and loss: “We ignore at our peril the fact that these natural systems – in other words, Nature’s own economy – provide the foundation for our prosperity and our national security.”

Perhaps his most pointed remarks – and those that generated the loudest applause from some (although not all) in the hall – were directed at the US itself. He described Congress as “this citadel of democracy created to represent the voice of all American people”. He mentioned the role of Magna Carta in laying the foundation for the constitutional principle that “executive power is subject to checks and balances”. Trump’s opponents clearly enjoyed that.

Saving the special relationship

State visits by British monarchs to the US have been relatively rare, and state visits to London by US presidents are even rarer. Trump is unique in having made two. This in itself is a mark of the desperate attempts by British governments, both Tory and Labour, to find ways of managing relations with his administration. This desperation was also apparent in Keir Starmer’s reckless decision to appoint Peter Mandelson as British ambassador to Washington.

The king’s speech pushed in interesting ways at the boundaries of what a British monarch might be expected to have said in Trump’s America. Yet some of the sentiments in his mother’s 1991 address to Congress – considered uncontroversial at the time – could no longer be expressed without the risk of offending the current administration.

Queen Elizabeth noted: “Some people believe that power grows from the barrel of a gun. So it can, but history shows us that it never grows well nor for very long. Force, in the end, is sterile.”

That may be a lesson Trump will have to learn the hard way. But for the moment, he and his immediate circle seem to have an unwavering belief in the primacy of kinetic force, and have little interest in the objective Charles described of stemming “the beating of ploughshares into swords”.

The queen also commended “the rich ethnic diversity of both our societies”. Charles spoke instead about interfaith understanding. This is not quite the same thing – but is certainly more compatible with the Trump administration’s disturbingly relaxed approach to the rise of white-supremacist politics.

Perhaps the saddest feature of a comparison of the two speeches is the queen’s proud boast in 1991 that “Britain is at the heart of a growing movement towards greater cohesion within Europe, and within the European Community in particular”. If the US has changed since 1991, so has Britain. It would be nice to think that one day the monarch might give an equally generous speech about shared history and values in front of the UK’s European neighbours.

On May 6 1954, Sir Roger Bannister did what was deemed impossible in athletics: he ran a mile in less than four minutes.

The milestone was celebrated worldwide, not just by athletics fans. It was considered at the time to be a similar achievement to scaling Mount Everest for the first time, which Sir Edmund Hilary and Tenzing Norgay had done the year before.

On Sunday, Kenya’s Sabastian Sawe and Ethiopia’s Yomif Kejelcha achieved a breakthrough comparable to Bannister’s some 72 years ago: running the 42 kilometres of a marathon in less than two hours.

Let’s break down this new benchmark and work out how these athletes were able to do it.

What happened in London?

Sawe smashed the men’s world record by an astonishing 65 seconds in winning the event in 1 hour, 59 minutes and 30 seconds.

Kejelcha – remarkably running in his first marathon – also crossed the line in under two hours (1:59:41).

The race was blisteringly fast. Even third-place getter Jacob Kiplimo of Uganda broke the previous world record – set in 2023 by Kenya’s Kelvin Kiptum in the United States – by seven seconds (finishing in 2:00:28).

Sawe ran quicker as the marathon went on, covering the second half of the race in 59:01. He pulled clear of Kejelcha after about 30 kilometres and made his solo break in the final two kilometres.

After the race, Sawe said:

I’ve made history today in London, and for the next generation I’ve shown them that nothing is impossible. Everything is possible, with a matter of time.

The training and nutrition

Sawe’s team said he trained by running up to 240 kilometres a week and fuelled himself before the race with bread and honey.

This reported training volume is likely an important factor in running a sub two-hour marathon.

Running up to 240 kilometres a week is beyond what most runners can tolerate. But high training volume, especially when much of it is done at relatively low intensity, is associated with faster marathon performances.

Nutrition during the race was also well planned.

A two-hour marathon is run at such high intensity that carbohydrate intake becomes important to maintain performance. The body stores carbohydrate in the muscles and liver but those stores are limited.

According to his nutrition team, Sawe took a carbohydrate drink and a gel leading up to the start, then used carbohydrate drinks and gels throughout the race.

His reported intake averaged about 115 grams of carbohydrate per hour.

While this is not a recommendation for the recreational runner, at the intensity required to run a two-hour marathon, it helps to maintain energy supply and pace late in the race.

The physiology

Although Sawe and Kejelcha’s laboratory data are not public, the physiology required to run a fast marathon is due to three main attributes:

• an exceptional capacity to take in and use oxygen during running

• the ability to maintain a high fraction of that capacity for prolonged periods

• an exceptional running economy, which means using less oxygen at a given speed.

Exceptional marathon performances also depend on durability, which is the ability to prevent deterioration of these qualities throughout the race.

What about the shoe?

Sawe and Kejelcha wore the lightest “supershoe” in history: Adidas’ Adios Pro Evo 3.

Adidas says it is “the fastest and lightest supershoe ever made”. It weighs less than 100 grams.

Supershoes can improve running economy by about 4% compared with conventional racing shoes.

The Adios Pro Evo 3 combines several features common in supershoes: very low weight, thick resilient foam and a stiff carbon-based structure in the midsole. The heel thickness is reported to be 39 millimetres, just under the 40mm limit permitted by World Athletics.

While most runners benefit from supershoes, the effect is variable and not the same for all runners.

Researchers have suggested this is due to two ways in which the footwear interacts with the runner.

Firstly, the foam and stiffening element can affect the “spring-like” bounce of the body as the foot hits and leaves the ground.

Secondly, they can change how the runner moves, including how the foot and ankle work, how long the foot stays on the ground, and the timing of energy return. As such, a shoe may be capable of storing and returning more energy, but the athlete still has to interact with it effectively.

The exact benefit of the Adios Pro Evo 3 over other supershoes has not been independently measured, but even small improvements are likely to be important over a marathon.

The conditions in London also likely contributed to these performances. While London is considered to be a relatively fast course (although not as fast as Berlin), the weather conditions were close to ideal: between 13-17°C during the race, which is at the upper end of the theoretical optimum for marathon running but within the range associated with fast endurance performance.

A perfect storm

As recently as 2017, a sub-two hour marathon was considered unlikely to occur for generations.

The best explanation for the performances in London is the convergence of many factors including exceptional physiology, years of high-volume training, efficient biomechanics helped by the use of advanced footwear, optimised fuelling and favourable weather conditions.

Meta and Microsoft are the latest software companies to announce big cuts to their global workforce. Both companies are also making big investments in artificial intelligence (AI).

The link seems obvious. Meta’s chief people officer, Janelle Gale, said the job cuts – about 10% of staff or almost 8,000 workers – serve to “offset the other investments we’re making”. Meta boss Mark Zuckerberg has previously spoken about a “major AI acceleration” with spending in excess of US$115bn planned this year.

Microsoft is also betting big on AI. The company also just announced early retirement packages for about 7% of its US workforce.

The two tech giants join Atlassian, Block, WiseTech Global and Oracle, who have all made similar announcements this year, each evoking AI without outright blaming it.

What is happening here? How we understand these layoffs depends on what we think AI is, and what implications it will have. Broadly speaking, there are three ways of looking at it: that AI is superintelligence, that it’s mostly hype, and that it’s a useful tool.

The end of white-collar work?

In the first view, AI is emerging superintelligence. It is a new kind of mind, that learns, reasons, and will soon outperform humans at most cognitive tasks (hint: it’s not!).

The job losses are not just a corporate restructuring. They are an early tremor of something seismic.

In February 2026, AI entrepreneur Matt Shumer put this view vividly – comparing the current moment to the strange, quiet weeks before COVID-19 broke into global consciousness. Most people, he argued, haven’t yet realised we are facing an “intelligence explosion”.

The essay drew significant criticism. Commentators noted it contained little hard data and read at times like a pitch for Shumer’s company’s own AI products.

But it captured a genuine anxiety. Something real is happening in software engineering, at least, where tasks are well-defined and success is easy to verify.

But the leap to “all white-collar work will be automated” is a big one. The view that AI is a kind of universal mind that learns and improves itself is far-fetched.

And most professional work is far messier than coding: ambiguous briefs, competing stakeholder interests, outputs that are hard to verify, and shifting success criteria. Coding may be a canary in the coal mine, but coal mines and boardrooms are very different places.

Are tech companies winding back hiring sprees?

The second view sees the conversation around AI as mostly hype. AI is being invoked as cover. Companies that hired aggressively during the pandemic boom, and now face financial pressure, are blaming AI as the more palatable explanation.

OpenAI CEO Sam Altman called this dynamic “AI washing”: companies blaming AI for layoffs they would have made regardless.

For example, Meta announced in March it would shut down its Metaverse platform Horizon World by June. Reality Labs, the division developing the technology, employed 15,000 people as of January 2026.

We don’t know in detail the make-up of the present job cuts, so Meta may just be repackaging earlier failures as AI-driven productivity gains.

Another cynical reading suggests that laying off workers in the name of AI is a way to drive up stock prices. When Block invoked AI and cut nearly 4,000 roles, its stock jumped the following day.

Announce AI-driven layoffs and you may find investors reward you for being future-focused. It is a historically familiar trick: technology has repeatedly served as convenient cover for financial restructuring.

Are layoffs a way to make staff use AI?

The third view is more nuanced. It sees AI as a powerful tool, but one that companies will need to transform themselves to take advantage of.

This has implications for what jobs are needed and in what quantities. We think this view has the most merit.

On this reading, the tech leaders believe AI will change how software gets built. But they don’t know exactly how.

So they do what tech companies often do when faced with uncertainty: they create pressure. They cut headcount staff, expect those remaining to produce just as much as before, and force teams to find ways to meet those expectations using AI.

It’s not a bet that AI will do everything, but that the pressure will force humans to work out how to use AI to increase productivity.

This also lines up with industry experience. For example, Google chief executive Sundar Pichai claims a 10% increase in engineering speed from AI adoption across the company. This could tally with cuts of around 7–10% of total workforce for most of the mentioned companies.

What this means for knowledge workers

These three views are often presented as mutually exclusive. In practice, all three expectations exist simultaneously. The honest answer to “what is really happening here” is probably “a bit of everything”.

What is true is that software development tends to be an early indicator of broader shifts in knowledge work. Productivity benefits from AI are real for those who adopt it. Yet adoption is unevenly distributed, and lags in less technical industries.

In this context, the ability to understand AI and make good decisions about how and where to use it is becoming a baseline professional skill.

The workers most at risk are not necessarily those whose tasks can be replicated by AI. They are those who wait for pressure to arrive from outside rather than getting ahead of it now.

We will have answers to the question of whether AI is mostly hype or a useful tool in the next few years.

If Meta, Microsoft, and their peers rehire staff with different skills, redesign workflows, and emerge genuinely more capable, the case for useful AI looks good. If they simply pocket the payroll savings, the cynics were right.

If you want to know where tech companies are going, don’t look at what they cut – watch what they hire.
