Could the Strait of Malacca be the next global flashpoint?

While recent global attention has focused on the Strait of Hormuz, which Iran has effectively held closed since late February in a move that has disrupted world energy supplies, a quieter but also important development has been taking shape in south-east Asia.

On April 14, the US and Indonesia announced a “major defence cooperation partnership”, strengthening their military ties. According to reports, the US is also seeking to gain wider access to Indonesian airspace. Several media outlets say Indonesia’s president, Prabowo Subianto, has approved the proposal.

These developments matter because Indonesia’s vast archipelago sits astride some of the most critical sea routes in the world. These include the Strait of Malacca, an important chokepoint for global shipping and trade. The region surrounding Malacca has seen growing military attention from outside powers in recent years.

Both the US and China have been steadily expanding their military presence around the strait and its approaches. The US has largely done so through base access and naval deployments, and China through its port network and naval buildup. The Andaman and Nicobar Islands, located near the strait’s western approaches, also provide India with a strategic presence in the region.

South-east Asia is becoming more explicitly tied into great-power competition, with the new US-Indonesia defence partnership adding the latest layer. Should this competition intensify – whether through a crisis in Taiwan, a spillover from Hormuz or a shift in alliances – the Strait of Malacca would be at the centre of it.

The strait is the shortest sea route connecting the Indian Ocean to the South China Sea and Pacific Ocean, making it the default corridor for trade between east Asia and the west. It stretches roughly 900km from the Malay Peninsula to the Indonesian island of Sumatra. At its narrowest point, the Phillips Channel near Singapore, it is barely 2.8km wide.

Almost 24% of global seaborne trade by volume flows through the strait. It carries 45% of the world’s seaborne oil, over 25% of all cars traded internationally and 23% of dry bulk cargo including key agricultural commodities like grains and soybeans. A large portion of European imports of electronics, consumer products like footwear and toys, machinery and industrial goods pass through the strait in sea containers as well.

The strait is also home to some of the world’s most critical port infrastructure. Singapore, located at the strait’s southern entrance, is the second-busiest container port and the busiest container transshipment hub on the planet. It handles over 40 million containers a year and is the world’s largest ship refuelling hub. Port Klang in Malaysia ranks among the world’s top ten container ports too, handling 14 million containers annually.

Why Malacca is irreplaceable

The most commonly cited detours around the Strait of Malacca, the Sunda and Lombok Straits, both lie within Indonesian territory and neither is a straightforward substitute. Rerouting through either adds roughly 1,000 to 1,500 nautical miles to the journey – three to five extra days at sea – along with higher fuel costs and the loss of Singapore’s refueling infrastructure.

Beyond Indonesia, the Torres Strait near Papua New Guinea is too shallow for large commercial vessels with a draft of over 12 metres. Ships avoiding all these routes would face a detour around the entire Australian continent, adding another ten to 15 days of transit time. These geographical features are the reason why the Strait of Malacca is so difficult to bypass.

China understands the risk of relying on Malacca perhaps better than anyone. In 2003, the then-president of China, Hu Jintao, coined the phrase “Malacca dilemma” to describe a strategic exposure that has continued since. Between 75% and 80% of China’s imported oil still passes through the strait.

Beijing has invested heavily in alternatives, but none come close to matching the scale of what transits Malacca. Pipelines running from Kyaukpyu on the Bay of Bengal in Myanmar into Yunnan province in China bypass Malacca entirely. However, their capacity is only around 440,000 barrels per day, a small fraction of China’s roughly 11 million barrels of daily oil imports.

The China-Pakistan Economic Corridor plans to link Gwadar Port on the Arabian Sea to Xinjiang in north-west China through road, rail and energy infrastructure. But it remains only partially developed, with its completion affected by difficult terrain and security challenges in parts of Pakistan. China has also diversified through Central Asian oil and gas pipelines, which provide about 10% of its total imported oil.

There are rail freight corridors connecting China to Europe, which avoid maritime chokepoints entirely and are faster than shipping. However, they are far more expensive and very limited in capacity. Arctic shipping routes along Russia’s northern coast offer a longer-term hedge, cutting the distance between Asia and Europe, but remain seasonal and marginal in global trade terms.

For now, there is no clear indication that the growing military presence around the Strait of Malacca will have any impact on commercial shipping. But if a conflict does arise in the future, it will be trade-dependent economies like China that will suffer.

Claim check: does your pint of beer really come with a ‘surprising health benefit’?

Source: The Conversation – UK – By Chloe Casey, Lecturer in Nutrition and Behaviour, Bournemouth University

Face Portraits/Shutterstock.com

Beer could come with a “surprising health benefit”, according to a new report from the BBC. This must be pleasing news for beer drinkers everywhere. But what did the new study the BBC report was based on actually say? And does it stand up to scrutiny?

The study, published in the Journal of Agricultural and Food Chemistry, set out to assess the vitamin B6 content of alcohol-free and full-strength beers. Vitamin B6 is an essential nutrient with important roles in the body, but there are problems with how these findings are framed.

The numbers are technically true but misleading in context. Saying that a beer provides 15% of your daily vitamin B6 sounds impressive, but it ignores the wider dietary picture.

Most people in the UK are not deficient in vitamin B6. And the same amount, or more, can easily be obtained from a standard healthy diet. A number of foods, such as potatoes, chickpeas, fortified cereals, grains, meat and vegetables, provide vitamin B6 without the need for alcohol.

The paper also links vitamin B6 to important neurological functions, but does not provide evidence that beer consumption meaningfully improves brain health. It correctly states that vitamin B6 is involved in making the brain chemicals serotonin and dopamine, and confirms that beer contains measurable amounts of B6. However, the interpretation that beer is therefore “brain boosting” is problematic.

The study does not measure brain health outcomes of any kind (not cognition, mood or neurological effects), so such conclusions are not supported by the data. The B6 intake from beer is modest, and this narrative overlooks the well established harms associated with alcohol consumption.

The serving size framing is also concerning. The study refers to “a serving” and, in some cases, volumes of up to a litre. Drinking at those levels on a regular basis would clearly conflict with NHS guidance on alcohol consumption. A typical half-litre serving was reported to provide around 13–16% of daily vitamin B6 requirements. A beer would need to provide about one whole day’s worth of vitamin B6 in a standard pint to qualify for a health claim. None of the beers in the study came close to that.

The study also does not adequately emphasise alcohol’s downsides, including risks to the liver, brain and increased cancer incidence. In recognition of these harms, the World Health Organization states that there is no safe level of alcohol consumption. Although this is acknowledged in the paper, highlighting a small vitamin content without properly weighing it against these risks is misleading.

When drinks brands latch on to studies like this to make their products seem good for you, they’re putting marketing ahead of public health. At worst, they’re nudging people to drink more.

A familiar story: the red wine myth

This is not the first time narratives about the health benefits of alcohol have found their way into the media. The idea that a glass of red wine a day is good for your heart is one of the most enduring examples. While this claim has some scientific roots, it is now heavily debated.

The belief largely traces back to the so-called “French paradox”, coined following observations that people in France appeared to have relatively low rates of heart disease despite diets rich in saturated fat and regular alcohol consumption. Red wine, in particular, has been suggested to offer some health benefits because it contains natural compounds called polyphenols – especially one called resveratrol – which can act as antioxidants and help protect the body’s cells.

Later studies, however, have raised serious concerns about these claims. Researchers pointed out that other factors – like people’s diet, how active they are and their access to healthcare – may have influenced the results. There has also been a wider rethink of alcohol’s effects, with growing evidence that it can increase the risk of harm, especially from certain types of cancer.

Taken together, these issues help explain a pattern known as the “healthy user effect”. At first glance, observational data suggest that moderate alcohol consumption may be protective. Some studies report lower rates of heart disease among moderate drinkers compared with non-drinkers. But observational data can only show correlations, not cause and effect.

In reality, moderate wine drinkers often differ from non-drinkers in important ways. They are, on average, more likely to eat healthier diets, be more physically active, be wealthier, have more friends, and see their doctor more often.

Each of these factors independently reduces the risk of heart disease and stroke. When they are not fully accounted for, alcohol itself can mistakenly appear to be the protective factor.

When the wider body of evidence is considered, particularly research linking alcohol to cancer, liver disease and mental health problems, most reviews conclude that any potential benefits are small and probably outweighed by the risks. The nutritional contributions of beer and wine do exist, but they are minor and unlikely to translate into meaningful health improvements.

Polyphenols, antioxidants, vitamins and minerals can all be obtained more safely and reliably from fruits, vegetables, whole grains, legumes, olive oil and other whole foods, without the risks associated with alcohol.

Arandora Star sinking: a lesser known Nazi war crime that spawned generations of conspiracy theories

Source: The Conversation – UK – By Simona Palladino, Senior Lecturer in Social Sciences, Liverpool Hope University

Just days before the Battle of Britain began in July 1940, more than 800 civilians were killed off the coast of Ireland when a German U-Boat sank a converted five-star cruise ship.

The people on board were German, Austrian and Italian internees – deemed enemy aliens by the UK government – who were being deported to Canada.

Why the Nazis sank a civilian ship has never been fully explained.

But the sinking of the Arandora Star remains one of the lesser known war crimes of the second world war.

My research has examined the oral histories of some of the Italian families, based in the UK, who remember the second world war. My latest project has looked into the long-term effects of Arandora Star sinking as it was experienced and transmitted across generations.

The attack

The Arandora Star was a first class cruise liner built in 1927 by the Cammell Laird Company Ltd, in Birkenhead, near Liverpool. It was one of the best-known ships in the world at the time.

When the war broke out, the Arandora, like many commercial ships, was placed at the disposal of the British government. Under the command of Captain E.W. Moulton, the Arandora was ordered to carry German, Austrian and Italian internees from Liverpool to Canada.

More than 1,600 men were forced onto the ship which was actually designed to carry 500. Internees were crammed below decks and the exits were guarded by barbed wire.

On July 2 1940 – the morning after it embarked on its voyage – the Arandora was torpedoed by a German U-boat, 100 miles northwest of Ireland.

Around 805 men, over 50 percent of the total number drowned, were Italian. About 100 British soldiers and crew members also lost their life, including the ship’s captain.

One British sailor told the press in 1940 that the Arandora Star turned half over on her side and sank, carrying down the occupants of several life rafts. “When the ship disappeared,” the sailor said, “there were hundreds of men on her decks … A cloud of steam rose a hundred feet in the air, and the suction dragged rafts and men underneath with her”.

But the ship’s traumatic final moments were just the start of the story for the families of those involved.

Part of my study involved making a 15-minute documentary, entitled The Arandora Star Sinking, to raise awareness about the xenophobia and discrimination faced by the people and communities who were left behind.

The film captures memories of the incident from the perspective of one of the descendants.

Vincenzo Margiotta

Vincenzo Margiotta is a third generation Italian based in Liverpool, whose grandfather was interned and died on the Arandora Star.

Margiotta’s family migrated to Scotland at the beginning of the 20th century, from Picinisco, Lazio, and established businesses in catering.

“Things were great. Life was good,” he said – until the outbreak of the second world war. Following Benito Mussolini’s declaration of war, on June 10 1940, anti-Italian feeling erupted among British citizens.

Around 4,500 Italian men between the ages of 16 and 70 with less than 20 years’ residence in Britain were ordered to be interned, including Margiotta’s grandfather.

Research has shown how Italian internees were regarded as the most “dangerous characters”. They were deported even though their degree of loyalty to the fascists had not been assessed.

Public opinion in the UK was initially in favour of the internment of “enemy aliens”. However, after the tragedy of the Arandora Star – and as a result of campaigns by various members of parliament – opinion changed and supported the release of “loyal” internees. Eventually internees were able to apply for release and many of them served in the armed forces.

Information vacuum

Over the years, Margiotta heard many stories about what happened to his grandfather.

One reason for this is because the official history was unclear. Why, for example, were none of the deportation transport ships marked as carrying prisoners of war? Instead, they set sail unaccompanied, equipped with anti-submarine guns, and employing a zigzag pattern in their movements – making the ships obvious targets for German U-boats.

Research has also shown that next of kin of internees were not informed about the Arandora disaster for weeks and only some families received a notification of “missing presumed drowned”, in April 1941, when the Home Office missing list was finalised.

Consequently, memories transmitted via word of mouth among family and community members were the main sources this group had available to them.

Margiotta said: “My knowledge of the incident was hearing stories around the table from other families”, adding:

Somebody pushed my grandfather off the ship, and told him to jump into the water … he was frightened, as he couldn’t swim – screaming in disbelief at what was happening around him … and then was never seen again.

This spoken mode of transmission of memories might have contributed to speculation and intrigue. The sinking has been subject to divergent tales and invention.

Gold bullion?

Margiotta said conspiracy theories included, “stories of it carrying gold bullion to take to Canada to fund the war chest for the UK … it was carrying soldiers; lots of stories. All have been unfounded. But I guess there is a story somewhere that needs to come out”.

It is evident how the lack of official information and records caused a sense of injustice for the loss of civilians. As Margiotta told me at the end of our interview:

…Why would the enemy wish to torpedo a ship like that? Why was a converted five-star cruise ship … torpedoed? There’s a lot of unanswered questions.

Margiotta represents just one of the many victims’ relatives who expressed the need to find answers to these basic questions.

In my previous research I spoke to Anglo-Italian families in the north-east of England who all shared the same pain and frustration. It’s time these questions were answered.

The cost of toxic leadership in the workplace – and how to avoid it

Source: The Conversation – UK – By Kristina Shea, PhD Candidate, RCSI University of Medicine and Health Sciences

You will probably recognise toxic leaders when you encounter them. They are the ones whose presence shifts the atmosphere, whose emails create unease, or whose behaviour limits the thinking of others. They often interrupt, frequently overlook contributions and hamper other people’s growth. While this behaviour is often seen as unfortunate but acceptable, the impact on employee wellbeing is corrosive.

Leadership shapes not only what people do, but how they experience their work and how they see themselves. In other words, leaders are responsible for the psychological environments they create. Research has highlighted leadership as a central influence on employee wellbeing.

Unfortunately, most employees report having experienced at least one toxic manager at some point. Even well-intentioned leaders may, at times, engage in toxic behaviour that diminishes others.

Our new research shows consistent declines across all dimensions of the wellbeing of employees who report to toxic leaders. Results from 273 employees highlighted negative impacts on emotions, engagement, relationships, meaning and accomplishment. The most pronounced effects showed up in their mindset and physical health, and affected employees said they experienced less enjoyment in their work and less sense of purpose.

From a psychological perspective, our findings are concerning. Positive emotions, engagement, healthy relationships, meaning and accomplishment are central to humans’ ability to thrive. Without these, work becomes something to endure rather than a context for growth.

These experiences rarely remain confined to the workplace; they tend to influence broader aspects of life. The happiness of employees has been found to have an impact on an employer’s bottom line – employees who experienced joy at work achieved 25% higher sales per hour, according to one analysis.

In fact, research has found that having emotional needs met, feeling valued and doing meaningful work could even be stronger predictors of performance than pay.

How toxic energy spreads

Leaders contribute to the energy of a workplace through their everyday interactions in what is known as “emotional contagion”. This is the process by which emotions and moods transfer between people through everyday interaction. When that energy is toxic, it can spread through teams and organisations, shaping how people feel and relate to one another.

The good news is that emotional contagion works both ways. Our research also looked at something known as “positively energising leadership” (PEL). This offers a way of understanding leadership as a force that enhances the capacity of others. Positively energising leaders are capable of producing extraordinary results and can drive positive outcomes in the workplace.

These leaders can be defined by two dimensions. The first is relational energy – the kind of energy that arises through interaction. For example, a manager who greets team members by asking about their weekend, listens to the answers and remembers them the next week can generate more relational energy in three minutes than a leader who sends dozens of emails over the course of a day.

Unlike physical energy, relational energy can be created and shared through attention, connection and presence.

Just asking a question and paying attention to the answer can be powerful.

The second is virtuous behaviour. This includes expressing gratitude, demonstrating integrity, offering support and treating others with respect. Taking time to listen to colleagues is a powerful way of building connection and strengthening relationships.

For leaders, there are three key practical implications. The first is to approach interactions thinking about how you might help the other person feel capable and valued. The second is to attend to your own wellbeing. The third is to invite feedback on your impact, asking employees how you can be a better leader and enhance their wellbeing. This information allows you to refine and enhance your leadership skills.

For employees working under a toxic leader, the situation is more difficult. However, there are a few things that you can do. Where possible, seek out positive relational energy from other sources: supportive peers or colleagues in other teams. This can buffer the negative effects of a toxic leader.

It is also helpful to allocate time for recovery and small wellbeing practices outside the work context. Finally, consider raising your concerns through trusted people like coaches, mentors or HR colleagues. It is important to reflect honestly on whether you will be able to sustain your performance and wellbeing under a toxic leader.

Leadership is expressed through everyday moments. In every interaction, leaders contribute to an environment in which people can thrive or one in which they feel diminished. These moments shape whether workplaces become spaces where people realise their potential or just places they must endure.

The BBC is axing Football Focus – here’s what it means for sports broadcasting

Source: The Conversation – UK – By Richard Jones, Director of Journalism, Politics and Contemporary History, University of Salford

The BBC has announced the end of one of its longest-running programmes, Football Focus.

It’s been a fixture of Saturday lunchtimes since 1974. But the final whistle will blow when this season finishes. The BBC has blamed a decline in audience for the BBC One broadcast as fans now get their pre-match news and views from a wider range of sources.

This isn’t a sign that the BBC is moving away from football. Research in my forthcoming book Sports Journalism in the UK, shows that 60% of the content on the BBC Sport X account is now about football, compared to 39% in its traditional sports bulletins on Radio 5 Live.

The BBC is also transforming its previously cautious approach to YouTube, with new video-first sports podcasts and channels, as it seeks to meet younger audiences on their favourite platforms. The old Football Focus slot will be going to Kelly Somers’ The Football Interview, a more in-depth weekly conversation on iPlayer that you’re already as likely to watch on your phone as the TV.

Another venerable BBC football programme, Match of the Day, suffered a similar drop in ratings in its traditional Saturday night slot. The BBC responded by making its valuable clips of Premier League highlights available online earlier. But one effect of the expansion of the Match of the Day brand has been to make Football Focus a less visible part of the BBC’s extensive football coverage.

The Wayne Rooney Show is a podcast created for BBC Sounds.

Some online commentary has blamed declining ratings on a so-called “woke” takeover of Football Focus, pointing to the appointment in 2021 of its first regular female host Alex Scott and the introduction of more items about women’s football. Some male critics have argued the BBC is part of a conspiracy to give the women’s game a prominence it doesn’t deserve.

Yet the BBC and others have argued that women’s football drives audiences and engagement. The public broadcaster’s coverage of women’s football has been rewarded with rising viewing figures of England’s success at major tournaments. In the year to 2024, the government’s participation survey found women’s football was the second most watched sport on British television, behind only men’s football.

In the era of pay TV networks, which outbid terrestrial broadcasters for the rights to many of the major sports leagues, tournaments and events, sport tended to be pushed to the margins of free-to-air television, relegated to weekend afternoons and nighttime highlights. But this is not to say it is not still an important part of the free-to-air offer: by 2024, the BBC, ITV, Channel 4 and Channel 5, spent £700 million between them on sport, more than any other genre of new, original programming. Yet it is live sport, not related shows such as Football Focus, which we’re mainly tuning in for.

The BBC faces a difficult broader context. It is under pressure to limit spending and BBC Sport is no exception. The BBC is not showing this summer’s Commonwealth Games live from Glasgow on television, a decision that would have been unthinkable in the past. All broadcasters now regularly have their commentators sitting in studios or at home describing the action from television pictures, to cut production costs.

The legacy of Football Focus

While it may now look like a holdover from a bygone age, Football Focus will go down as an important programme in British sports media history. An earlier version, Football Preview, began in September 1967 as part of the BBC’s old multi-sport magazine show, Grandstand. It was an innovative development, bringing regular football discussion and analysis from the pages of newspapers onto the screen.

Extended and relaunched seven years later with host Bob Wilson, Football Focus was often directly up against ITV rivals On The Ball (1965-1985, then 1998-2004) and Saint & Greavsie (1985-1992). These shows helped pioneer the now familiar diet of football previews, interviews and punditry. Each enjoyed the sort of pre-match access to players and managers now often restricted by clubs and leagues keen to keep their best material for themselves.

When the BBC briefly lost the rights to Premier League highlights in 2001, both Football Focus and results show Final Score were spun out as separate programmes to help maintain the prominence of football on the BBC. It worked: Football Focus lasted almost two decades after its mothership Grandstand finally came off the air in 2007. The falling number of top flight 3pm kick offs certainly didn’t help though, and that trend might in time make it harder for even Final Score to endure, too.

Intense competition in a sport environment saturated by media, meant Football Focus struggled to remain distinctive. Fans can now get everything from detailed tactical analysis to outrageous hot takes from content creators large and small. These offer the sort of depth and partisan approach the BBC, constrained by limitations of time, resources and objectivity, cannot.

Ghosts of the past have come back to haunt the BBC. That Peter Crouch Podcast, launched by the BBC, is the UK’s most popular football podcast, according to Edison Research. The only problem is that it’s been on commercial platform Acast since 2022. Meanwhile, ex-Football Focus host Gary Lineker’s Goalhanger stable includes three of the UK’s top six podcasts overall, including his own The Rest is Football, coming soon to Netflix.

Then there’s the sometime Dragon’s Den star, Gary Neville. The footballer turned entrepreneur recently signed Mark Goldbridge to his expanding media network, The Overlap. As the face of YouTube channel The United Stand, Goldbridge has become arguably the most successful exponent yet of fan media, delivering unfiltered opinions on Manchester United from his home studio rather than the stadium. In true football transfer style, the deal was for an “undisclosed” fee.

All this adds up to a much busier football media market than the one Football Focus first entered. BBC Sport’s focus remains on football, perhaps increasingly so. But on Saturday lunchtimes at least, it’s going to be taking a different form.

Récord estratosférico en maratón: así rompieron dos atletas una barrera que se creía insuperable

Source: The Conversation – (in Spanish) – By Mark Connick, Postdoctoral Research Fellow, School of Exercise & Nutrition Sciences, Queensland University of Technology

El 6 de mayo de 1954, el atleta británico Roger Bannister logró lo que se consideraba imposible en el atletismo: corrió una milla (1 609,34 metros) en menos de cuatro minutos.

Este hito fue celebrado en todo el mundo, y no solo por los aficionados al atletismo. En aquel momento se consideró un logro similar a la primera ascensión al Everest, que Sir Edmund Hillary y Tenzing Norgay habían coronado el año anterior.

Este domingo, el keniano Sabastian Sawe y el etíope Yomif Kejelcha lograron una hazaña comparable a la de Bannister hace casi 72 años: correr los 42 kilómetros de una maratón en menos de dos horas.

Analicemos este nuevo hito y averigüemos cómo pudieron conseguirlo.

¿Qué ocurrió en Londres?

Sawe batió el récord mundial masculino por unos asombrosos 65 segundos al ganar la prueba en 1 hora, 59 minutos y 30 segundos.

Kejelcha –quien, sorprendentemente, corría su primer maratón– también cruzó la línea de meta en menos de dos horas (1:59:41).

La carrera fue increíblemente rápida. Incluso el tercer clasificado, Jacob Kiplimo, de Uganda, batió el anterior récord mundial –establecido en 2023 por el keniano Kelvin Kiptum en Estados Unidos– por siete segundos (terminó en 2:00:28).

Sawe corrió cada vez más rápido a medida que avanzaba el maratón, completando la segunda mitad de la carrera en 59:01. Se distanció de Kejelcha tras unos 30 kilómetros y se escapó en solitario en los dos últimos kilómetros.

Tras la carrera, Sawe declaró:

Hoy he hecho historia en Londres y he demostrado a la próxima generación que nada es imposible. Todo es posible, es solo cuestión de tiempo.

El entrenamiento y la nutrición

El equipo del atleta keniano afirmó que entrenaba hasta 240 kilómetros a la semana y se alimentaba antes de la carrera con pan y miel. Es probable que ese volumen de práctica sea un factor importante para correr una maratón en menos de dos horas.

Correr hasta 240 kilómetros a la semana supera lo que la mayoría de los corredores pueden soportar. Pero un volumen de entrenamiento elevado, especialmente cuando gran parte de él se realiza a una intensidad relativamente baja, se asocia con mejores resultados en maratón.

La nutrición durante la prueba también estuvo bien planificada. Una maratón de dos horas se corre a una intensidad tan alta que la ingesta de carbohidratos se vuelve importante para mantener el rendimiento. El cuerpo los almacena en los músculos y el hígado, pero las reservas son limitadas.

Según su equipo de nutrición, Sawe tomó una bebida con carbohidratos y un gel antes de la salida, y luego consumió bebidas y más geles con el mismo nutriente durante toda la carrera. Según sus informes, su ingesta media fue de unos 115 gramos de carbohidratos por hora.

Aunque esto no es recomendable para el corredor aficionado, ayuda a mantener el suministro de energía y el ritmo en las últimas etapas de la prueba a la intensidad necesaria.

La fisiología

Aunque los datos de laboratorio de Sawe y Kejelcha no son públicos, la fisiología necesaria para correr un maratón rápidamente se debe a tres atributos principales:

  • Una capacidad excepcional para absorber y utilizar oxígeno durante la carrera.

  • La aptitud para mantener una alta proporción de esa capacidad durante periodos prolongados.

  • Una economía de esfuerzo formidable, lo que significa utilizar menos oxígeno a una velocidad determinada.

Los resultados excepcionales en maratón también dependen de la resistencia, que es la capacidad de evitar el deterioro de las citadas cualidades a lo largo de la carrera.

¿Y qué hay de las zapatillas?

Sawe y Kejelcha llevaban las zapatillas más ligeras de la historia: las Adios Pro Evo 3 de Adidas, que pesan menos de 100 gramos y pueden mejorar la economía de carrera en aproximadamente un 4 % en comparación con las zapatillas de competición convencionales.

Las Adios Pro Evo 3 combinan varias características comunes en este tipo de calzado de vanguadia: peso muy reducido, espuma gruesa y resistente y una estructura rígida a base de carbono en la entresuela. Según se informa, el grosor del talón es de 39 milímetros, justo por debajo del límite de 40 mm permitido por World Athletics.

Aunque la mayoría de los corredores se benefician de las superzapatillas, el efecto no es el mismo para todos los corredores. Los investigadores han sugerido que esto se debe a dos formas en las que el calzado interactúa con el atleta:

  • En primer lugar, la espuma y el elemento de refuerzo pueden afectar al rebote “elástico” del cuerpo cuando el pie toca y se despega del suelo.

  • En segundo lugar, pueden alterar la forma en que se mueve el corredor, incluyendo cómo funcionan el pie y el tobillo, cuánto tiempo permanece el pie en el suelo y el momento en que se produce el retorno de energía. Por lo tanto, una zapatilla puede ser capaz de almacenar y devolver más energía, pero el atleta aún tiene que interactuar con ella de manera eficaz.

La ventaja exacta de las Adios Pro Evo 3 sobre otras zapatillas de alto rendimiento no se ha medido de forma independiente, pero es probable que incluso las pequeñas mejoras sean importantes en una maratón.

Tal vez las condiciones en la capital británica también contribuyeran a estos resultados. Si bien el recorrido de Londres se considera relativamente rápido (aunque no tanto como el de Berlín), las condiciones meteorológicas fueron casi ideales: entre 13 y 17 °C durante la carrera, lo que se sitúa en el extremo superior del óptimo teórico para correr una maratón, pero dentro del rango asociado al rendimiento de resistencia rápida.

Una tormenta perfecta

En 2017, se consideraba poco probable que se completara un maratón por debajo de las dos horas en varias generaciones.

La mejor explicación para lo que ocurrió el domingo en Londres es la convergencia de muchos factores, entre los que se incluyen una fisiología excepcional, años de entrenamiento de gran volumen, una biomecánica eficiente favorecida por el uso de calzado avanzado, una alimentación optimizada y unas condiciones meteorológicas favorables.

Potential signs of life on distant planets sound exciting – but confirmation can take years

Astronomers can use telescopes to find specific molecules in the atmospheres of neighboring planets, in nebulae – clouds of interstellar dust and gas – hundreds or thousands of light-years away, or in galaxies beyond the far reaches of the Milky Way.

So far, astronomers have found more than 350 molecules in the spaces between and around stars in just under a hundred years – the first such molecule was reported in 1937. Each year, the cosmic chemical stockroom grows by anywhere from a handful to a couple of dozen new finds. Many of these molecules are precursors to biomolecules, meaning they might provide hints about life’s origins elsewhere in the cosmos.

As an astrochemist, my research is all about chemicals found in space, especially in distant cosmic clouds where infant stars are born. Even so, the precise observations captured by these telescopes never cease to amaze me.

With this ongoing boom in astrochemical census data, there is a lot to be excited about. Sometimes, however, this excitement can be premature. Finding molecules in places people will likely never visit is no simple task, so vetting and sometimes correcting these observations is a continual process – especially for molecules whose signals aren’t as strong.

‘Seeing’ molecules in space

Astronomers can’t visit neighboring planets, let alone distant star-forming regions. So, how do they see what is out there?

Astronomers observe the cosmos with telescopes that collect all different wavelengths of electromagnetic energy. For astrochemistry, they typically use radio telescopes. These satellite-dishlike instruments are used to “see” radio waves, which have wavelengths much longer than the human eye can perceive.

When molecules freely tumble around as gases in space, they rotate, and this motion releases energy in the form of photons, or electromagnetic particles. Different types of rotations require different levels of energy. Each photon carries that energy with it to a telescope, which records its signal. The more photons of a given energy, the stronger that signal.

If a radio telescope records all of the expected signals for a given molecule – its spectrum – then astronomers can confidently say that they have detected that molecule.

Infrared telescopes, such as the James Webb Space Telescope, or telescopes that detect visible light, such as the Hubble Space Telescope, can also be used for astrochemistry. Both kinds of telescopes, however, collect chemical signals, which are often more difficult to distinguish from one another.

Knowing what to look for

Behind every discovery of a new molecule in space is months or even years of work to capture a chemical’s “fingerprints,” or its spectrum.

I spent about a year doing this kind of work at the University of Cologne in Germany as a Fulbright research fellow. There, I used computer models of astrophysically interesting chemicals to predict what their spectra would look like.

In the lab, I injected the chemicals into a glass tube held under vacuum to mimic conditions in space. Using sensitive instruments, I recorded what a radio telescope would see if it were looking at only that molecule.

Astronomers had already found some of these molecules in space, and my colleagues and I were reexamining them, but we were also looking at molecules that we predicted might exist somewhere in space.

I worked with a team of scientists to adjust the computer inputs over and over until the simulated spectra matched the experimental data. When simulated spectra matched the experiments, that meant that the simulated spectra reliably modeled what a molecule’s fingerprint looks like in space. Reliable model spectra allow astronomers to detect chemical features at frequencies beyond what they can measure in the laboratory.

While my contributions to the Cologne team didn’t lead to a discovery of a new molecule in space, I gained an appreciation for the work behind the scenes of molecule discovery. The laboratory measurements are done precisely so that astronomers can be confident in their detections.

When detections get cloudy

Even with powerful radio telescopes and thorough experiments, some detections aren’t quite as clear as astronomers would like them to be. Sometimes, the signals are too faint for astronomers to be totally confident that they represent the molecules they think they do. Other times, there are too many molecule signals crowded together, causing different signals to blend.

Scientists have detected molecules relevant to biological processes back on Earth in comets and the atmospheres of other planets. These detections are exciting, but most scientists exercise caution to avoid jumping to conclusions because those molecules generally can exist outside of living things.

Sometimes, however, the excitement overshadows the caution and leads to premature conclusions.

Scientists often get excited when new molecules, especially biologically relevant molecules, are potentially present, and they want to share those findings with the world. Some researchers are also concerned about being the first to publish a new result, especially because a lot of telescope data is publicly available after a brief proprietary period.

Perhaps one of the most exciting nondiscoveries in astrochemistry was that of glycine in interstellar space more than 20 years ago. Glycine is the simplest amino acid, a type of molecule essential for life as we know it. Finding this molecule in a nebula would change how scientists think about the evolution of life’s ingredients.

Follow-up studies showed that key signals were missing in the initial report of glycine. As a result, astrochemists now generally agree that glycine had not been found in star-forming nebulae.

More recently, another molecular discovery has been scrutinized: the potential detection of phosphine in Venus’ atmosphere. Unlike with glycine, scientists have not yet agreed on whether phosphine, which is associated with some biological processes on Earth, is indeed present on Venus.

Initial reports of phosphine on Venus spurred chatter about biosignatures and evidence of potential life on Earth’s much hotter sister planet. However, follow-up studies by other scientists couldn’t confirm the initial results.

Over the past five years, scientists have continued to try to confirm or definitively refute Venusian phosphine.

Vetting claims

When reading about discoveries of new molecules in interstellar space or on other planets, how can you be confident in the detections you are reading about? It’s important to watch out for flashy headlines that claim signs of life have been found elsewhere in the universe. Molecule discoveries that rely on only one or two signals being detected are generally less reliable than those based on five or more signals.

For discoveries that tease hints of life on other worlds, other scientists are almost certainly going to try to reproduce the results. If you wait a few months for the initial fanfare to die down, you can do a web search to see what new results have come out to support – or refute – the original claim.

Why is water wet?

Why is water wet? – Philip S., age 12, Northville, Michigan


Spring is often a rainy season. If you get caught in a downpour without an umbrella, you will quickly learn what it means to be wet. But what is it about water that makes it wet?

I am an atmospheric scientist, and water is a fundamental part of the atmosphere. I study storms and wildfires, both of which are closely connected to water.

Why water is wet has to do with how water molecules interact with each other and the things around them.

Wet you can see

Imagine you accidentally spill water on your clothes one day. You will notice two things: First, the water spreads out on the cloth, and the wet part sticks to your body more than the dry part does; and second, the wet area feels cool.

Wet clothes stick to your body and water spreads across the fabric because water molecules are strongly attracted to other molecules, a chemical property called adhesion.

One important reason why water molecules are so attracted to other molecules is that they’re polar. Like a microscopic magnet, one end of the molecule carries a small negative charge, while the other end carries a small positive charge.

Many everyday materials, such as glass, skin and clothing, are also polar. When water touches these surfaces, the electric charges on those materials attract the water molecules and hold them in place. This strong attraction also helps water spread out over surfaces. Whether something feels “wet” to you has to do with how good a liquid is at staying in contact with a surface. Water feels wet because its molecules stick tightly to each other and to your skin.

Compared to water, mercury has much weaker attraction to surfaces. Mercury’s molecules are much more attracted to each other, meaning they have very strong cohesion. As a result, mercury does not easily stick to other surfaces.

The cool feeling of being wet comes from evaporation. Liquids need energy to change into gas because they must overcome the forces holding molecules together before they can float away. They take this energy from their surroundings in the form of heat.

When you step out of a pool and the water on your swimsuit evaporates, you might feel cold because it’s taking away heat from your body. Wet things often feel cool because evaporation takes heat away from the skin. Sometimes something that feels cool can trick you into thinking it’s also wet, even if no liquid is actually present.

Evaporative cooling is very useful in daily life, and other liquids can also do it. For example, when you clean a wound with an alcohol wipe, it also feels cool. Like water, alcohol evaporates and carries heat away from your body. Similarly, when sweat evaporates, it removes heat from your body and cools you down.

Wet you cannot see

Sometimes you can feel damp even when you don’t see any water. This is related to the amount of water vapor in the air, also called humidity.

Air can hold only a limited amount of water vapor. When there is already a lot of water vapor in the air, evaporation slows down. This makes it harder for sweat on your skin to evaporate, so you feel sticky and wet.

When air becomes completely full of water vapor, the vapor starts to condense and turn back into liquid water to form dew or fog.

How much water vapor air can hold depends on temperature. Warm air can hold more water vapor, while cold air can hold less. As temperature increases, water molecules gain more energy and can more easily escape their attraction to each other and become a vapor.

This is why dark or shady places often feel damp. These areas get less sunlight, stay cooler and cannot hold much water vapor. As a result, water does not evaporate easily and the area stays wet.

A lot of water, but not wet

Because the air’s ability to hold water depends on temperature, sometimes the air can contain a lot of water vapor but you don’t feel wet.

For example, when you are near a fire, the burning process produces water vapor. However, because the temperature is also higher, the air can hold more water vapor. This speeds up evaporation. If there are wet clothes nearby, they may actually dry more quickly.

In weather forecasts, scientists use relative humidity to describe how humid the air feels, rather than the actual amount of water vapor in the air.

Because hot air can hold so much moisture that relative humidity stays low, people are often surprised when I tell them that wildfires release large amounts of water vapor. Fire is the last thing most people associate with being wet.

Older Americans who vote live longer than those who don’t – new research

Most people know the basics of healthy living that become more important as you grow older: Eat plenty of vegetables, exercise regularly, sleep well, have a social life, limit your alcohol consumption and don’t smoke.

As an economist and social psychologist who study altruism and health, we wondered whether civic engagement might play a role as well.

In 2022, the American Medical Association, an organization representing doctors, noted that voting could potentially have health benefits. So we conducted a study that directly tested this idea: We examined whether older Americans – people who are 65 and up – who vote live longer than nonvoters.

Older adults vote at a higher rate than younger adults in the United States. In Wisconsin, the focus of our study, the voting rate of older adults is even higher.

We used data from the Wisconsin Longitudinal Study, a study which has followed a randomly selected sample of Wisconsin high school graduates since 1957. We compared the long-term health of older adults who voted in the 2008 presidential election to those who did not vote in that election. Using objectively verified voting records from Catalist, which tracks Americans’ voting behavior, along with official National Death Index records, we found that voters were 45% less likely to die within five years after the 2008 election, 37% less likely to die 10 years after the election, and 29% less likely to die 15 years later.

We also examined voting in the 2004 and 2012 presidential elections and found that the results were stronger for more recent elections – those held in 2008 and 2012 – compared to the earlier one held in 2004.

You may wonder whether this is just because healthier people are more likely to vote in the first place.

It’s easier to vote when you’re healthy than when you’re not, but this does not fully explain our results. Voters still had a lower risk of dying when we controlled for demographic factors such as gender, marital status and income, other forms of civic engagement such as volunteering, and a voter’s health status prior to voting.

We also found that those in poorer health to begin with benefited more from voting 15 years later than those who had been healthier before they voted.

Here’s another finding: How someone voted didn’t matter. When we compared what happened to older adults who cast their ballots in person to those who mailed their ballots, we found that both groups had about an equally lower risk of dying over the 15-year period.

It also did not matter whether a voter’s preferred candidate won. We found that although it can be stressful when the candidate you support loses, the people we studied experienced similar long-term health benefits of voting regardless of their political affiliation.

Why it matters

Scientists have long known that people who volunteer for nonprofits experience many health benefits, including a longer lifespan.

Voting is, arguably, also an altruistically motivated act. That’s because individual voters are aware that their one vote will not change the outcome of a national election.

What still isn’t known

If you are wondering why voting predicts lower mortality risk, well, so did we.

One possibility is that as with other civic engagement activities, including volunteering, voting may trigger positive biological responses that support well-being. Other researchers have found ample evidence showing that volunteering can boost the brain’s reward system, reduce stress and even slow some aspects of aging.
Although we didn’t test for these in the Wisconsin Longitudinal Study, they may help explain why people who vote tend to have better health outcomes than those who don’t.

Voting might also improve health through a sense of self-efficacy, civic duty and social connection, since it is both an altruistic and shared activity.

Although the exact explanations aren’t known, studies consistently show a link between volunteering and a lower mortality risk, which suggests that participating in civic life – even something as simple as casting a ballot – may be good for your health, like going for a run or eating vegetables.

Perseverance doesn’t always pay off for companies – sometimes it’s better to ‘fail fast’

Source: The Conversation – USA (2) – By Scott Friend, Professor and Schaefer Endowed Chair in Marketing, University of Dayton

Across the business world, companies often double down on struggling ideas, retreating only after clear evidence shows they won’t work.

A recent spectacular example was Meta’s metaverse push. After the organization invested US$80 billion over several years, it announced changes in March 2026 that all but abandoned its grand strategy.

But many companies are following the opposite approach of quickly walking away from failure instead of blindly sticking to a vision. Google ended its cloud gaming service Stadia when it failed to take off, choosing instead to reuse the technology elsewhere. Mercedes abandoned its zero-sidepod F1 concept once it clearly hit a competitive dead end. And Slack transitioned from a failed gaming app to a ubiquitous intra-office messaging platform.

What drove all these decisions wasn’t a tolerance for failure. Instead, executives read signals of weakness early, confronted inconvenient evidence and changed course before greater losses accumulated. In other words, they embraced “failing fast.”

As business professors who study sales performance and sales failure, we argue that this concept is one of the most important yet most misunderstood ideas in our field. It’s not about celebrating mistakes or lowering standards, nor does it give leaders permission to abandon rigor or give up easily.

At its core, it’s about creating the conditions for faster learning: building the managerial discipline to recognize when an opportunity is unlikely to pay off, stopping before sunk costs deepen, and redirecting scarce resources to more promising bets. And this is a strategy that can work for any company, at any level, no matter how high or low the stakes.

The Slack model

Slack is everywhere these days. But few recall that it was actually founded in 2011 as a multiplayer online game called Glitch that failed to take off. The company, then known as Tiny Speck, shut it down in 2012, but in the process its leaders identified hidden value in an internal communication tool they had built simply to coordinate their own work.

This practical side project looked like a tool that could do well in the burgeoning market for team-collaboration software. So the company pivoted by deploying its remaining capital and talent to launch Slack in 2013. Since that time, Slack has become one of the fastest-growing enterprise software platforms in history, eventually leading to a
$27.7 billion acquisition by the business platform Salesforce in 2021.

Stories like these are often told as tales of persistence, but they’re actually examples of disciplined quitting. Similar cases include 3M’s accidental invention of Post-it Notes (first used as ad hoc bookmarks for hymnals); Shopify’s pivot from selling snowboards to enabling e-commerce infrastructure; and Instagram’s shift from a cluttered check-in app to a focused photo-sharing platform.

Together, these stories suggest that success depends not only on staying the course but also on recognizing early when the course is no longer worth pursuing and changing to a better one.

Know when (and how) to fold ‘em

Despite this history, much of business culture still promotes a simpler message that grit drives success.

This mindset, however, can also foster a sunk cost fallacy. Myriad examples of this trap linger across business lore to this day: Blockbuster failing to accept an offer to purchase Netflix and instead expanding its physical footprint model; Kodak inventing digital cameras but opting to prioritize its dominant film business; and the persistent joint venture funding of the Concord supersonic airliner despite strong evidence that the project wouldn’t become commercially viable. All three businesses eventually went bankrupt after once dominating their respective industry.

Sunk costs, in short, come into direct tension with notions of failing fast. But our research underscores the latter’s benefits, showing that associated payoffs extend beyond high-profile corporate pivots and even apply to everyday decision-making. Studies in business-to-business sales, for example, find that walking away early from low-potential opportunities can improve motivation and performance.

That said, there’s an important condition: This approach only works when executives and customer-facing personnel have a grounded understanding of what the company can do and what customers want – rather than treating early exit as a suboptimal default.

Across these varied cases, our research has pointed to another clear pattern that emerges: Failing fast is typically structured in a way to make decisions under uncertainty, with three distinct stages. Again, the origin story of Slack is a good example.

The first step is to gather information that suggests whether any given project will succeed. These signals can come from direct observation or data. The goal is to build an early, evidence-based picture of whether an effort is gaining traction. In the case of Slack, CEO Stewart Butterfield and his team recognized through direct user experience that Glitch, the game, just wasn’t fun. But they also saw other signals that showed structural limitations preventing a viable path to succeed on mobile devices.

The next step is to interpret the collected data – combining experience, contextual awareness and analytical tools to distinguish between ideas that warrant investment and those that don’t. Structured approaches, like comparing goals to historical benchmarks, can make sure that assessments are consistent and grounded in evidence rather than intuition alone. In Slack’s case with Glitch, Butterfield synthesized the early signals and concluded that, despite significant sunk costs, the game didn’t justify further resources.

The final and most difficult step is execution. When signals and analysis point to early exit as the most effective course, acting on that conclusion is hard. Withdrawing, even when continuing no longer makes strategic sense, feels counterintuitive in an environment that rewards persistence. That’s why executives need to make the case that there’s a smarter way to allocate time, capital and attention. With Slack, Butterfield followed through on his analytical convictions by shutting down the game and repurposing internal technology to create Slack – reframing this “failure” as a strategic reallocation.

A lesson for everyone

These lessons extend far beyond the world of sales, startup culture and Big Tech. Managers face similar choices in product development, partnerships and hiring – situations where the real risk is not failure, but failing late. This way, strong organizations understand how to fail by design. That is, defining success and failure criteria early, testing assumptions quickly and containing any downside before commitment becomes wasteful. These are, in fact, universal lessons that apply across industries, up and down the chain.

As a more poetic analogy, we turn to the sea. No skilled sailor tries to cross every channel. Some waters will test their endurance, while others will open up new routes. The best sailors prove sound judgment by reading the winds early and changing course before a storm takes hold.

Business leaders face the same choice. Growth comes from neither persistence alone nor reflexive retreat, but from knowing when the effort no longer creates value.
