Parks are public spaces – but private event organisers are muscling in

Tens of thousands of fans streamed into Manchester’s Heaton Park this summer to see Oasis return home. Over 400,000 people attended across five nights of the much-hyped reunion tour.

But the joy came at a price. For more than eight weeks, large parts of Heaton Park were fenced off and heavily secured, restricting everyday use. Families, dog-walkers and runners were displaced, and the effects rippled far beyond the park gates.

The park regularly hosts food festivals and the music festival Park Life, but Oasis was of a different scale. The concerts effectively turned much of the park into a private venue, accessible only to ticket holders and staff. Residents complained of overcrowded trams, gridlocked roads and children struggling to get home from school. What is usually Manchester’s largest green space became, in some people’s minds, a no-go zone for two months.

Local governments insist such events bring much-needed revenue. Manchester City Council has not reported a specific fee for Oasis to use Heaton Park, although it has been said that around £25,000 has been allocated to fund local projects. (At time of publication, the council had not replied to our request for clarification about the fee.)

Pubs and restaurants thrived on concertgoers, and taxi drivers got a ready-made source of customers who would pay whatever it took. The city itself basked in the global spotlight of a high-profile homecoming.

Yet the downsides for locals were obvious: noise, antisocial behaviour, litter and congestion, as well as the general fatigue of not being able to go about their daily business. Afterwards, many felt the grass and grounds had been left in a poor state, raising questions of how much – if any – of the fee would be reinvested in the park itself.

This fuels scepticism: a multi-million pound tour gives the council a relatively small fee, while thousands of locals absorb the inconvenience. In my view, people are right to wonder whether public parks should be used to support these enterprises.

The Oasis shows tap into a wider debate about the use of public parks for festivals and events. Why is a space designed for community relaxation doubling up as a mega-venue? Why not use a stadium or arena purpose-built for huge crowds? And why don’t local councils charge far greater fees to permit such events, and properly enforce penalties for any damage?

Heaton Park is not unique. Sefton Park in Liverpool and Finsbury Park in London have hosted major festivals including Africa Oye and Wireless for over a decade respectively, provoking annual complaints about noise and disruption. Each time, local councils stress the economic upside, while residents question whether public green spaces are being commercialised at their expense.

Why councils say yes

In my experience, many local authorities simply feel they cannot afford to say no. Years of budget cuts mean councils must “sweat” every asset they own. Large parks, especially those with capacity for mass gatherings, are among the few resources left to monetise.

Cultural prestige also matters. Hosting a band like Oasis in their hometown generates pride and attention that no council will want to turn away.

But if parks are to be used in this way, the terms should be stronger. The reported £25,000 fee is minimal when set against the profits of a five-night run: 80,000 people paying £100 or more each over five nights adds up to around £40 million in revenue. (In fact, many people paid hundreds and even thousands of pounds to attend the Oasis gigs.)

Councils could charge significantly more, with some of the revenue ring-fenced to fund park management and improvements, and contracts that cover damage to the park.

So, did Oasis ruin Heaton Park? Not exactly. The concerts were a cultural phenomenon for Manchester and a source of joy for thousands of fans. But they also highlighted how public parks are being commercialised to plug council finances, often with limited benefit to those who most need them.

If local authorities continue to hire out green spaces to private promoters, they should rethink the terms. At the very least, residents deserve more input, and a fairer share of the rewards.

The US has deployed warships near Venezuela in a cartel crackdown – but direct military action is unlikely

Source: The Conversation – UK – By Amalendu Misra, Professor of International Politics, Lancaster University

The US is ramping up its fight against Latin America’s drug cartels. Washington has deployed several naval warships into southern Caribbean waters, alongside over 2,000 marines. A guided missile cruiser, the USS Erie, and a nuclear-powered fast attack submarine, the USS Newport News, are also reportedly due to arrive in the region soon.

These moves take place as the Trump administration escalates pressure on the Venezuelan president, Nicolás Maduro, who has now accused the US of plotting to oust him from power.

Donald Trump has long called Maduro “one of the largest narcotics traffickers in the world”, saying he heads the Venezuelan Cartel of the Suns. The US recently doubled the reward for Maduro’s arrest to US$50 million (£37.1 million).

When asked about the possibility of direct military action in Venezuela, White House press secretary Karoline Leavitt remarked: “President Trump has been very clear and consistent. He’s prepared to use every element of American power to stop drugs from flooding into our country and to bring those responsible to justice.”

Latin America is no stranger to US military interventions and regime changes. Washington sponsored covert and overt military operations in the region, from Chile to Brazil and Guatemala to Grenada, that led to regime changes in the second half of the 20th century.

So the presence of a US military submarine and guided missile cruiser close to its territorial waters has justifiably rattled Venezuela’s leadership. Maduro has called on his countrymen and women to join nationalist militias, declaring: “no empire will touch the sacred soil of Venezuela”. And Venezuela’s navy has deployed warships and drones to patrol the coastline.

The Trump administration has said little about its intentions. But most analysts agree the US is not preparing to invade Venezuela. The naval build-up is much more likely to be an attempt to get Latin American governments to take stronger action against drug traffickers.

Falling in line

Cracking down on transnational drug cartels has become a defining theme of Trump’s second presidency. Shortly after returning to office in January, he issued an executive order formally designating eight of them “foreign terrorist organisations”.

This included six organisations based in Mexico: the Cartel del Golfo, Sinaloa Cartel, Cartel de Jalisco Nueva Generacion, Carteles Unidos, La Nueva Familia Michoacana and Cartel del Noreste. It also included the Mara Salvatrucha (more commonly known as MS-13), which originated in California, and the Venezuela-based Tren de Aragua.

A White House statement at the time said: “The Cartels have engaged in a campaign of violence and terror throughout the Western Hemisphere that has not only destabilized countries with significant importance for our national interests but also flooded the United States with deadly drugs, violent criminals, and vicious gangs.”

In August, Trump then signed a secret directive ordering the Pentagon to use military force against these cartels. The US secretary of state, Marco Rubio, has gone on record defending this directive. He said on August 7 that it allows the US to “use other elements of American power, intelligence agencies, the Department of Defense, whatever … to target these groups if we have an opportunity to do it.”

There are several legal issues associated with direct US military action in Latin America, which reduce the prospect of any such assault taking place. It would violate the sovereignty of countries there, while launching strikes without congressional approval or a UN mandate would risk breaching domestic prohibitions.

For instance, there are debates over whether murder charges could be brought against US service members acting outside of a congressionally authorised armed conflict if they were to kill civilians or criminal suspects who pose no imminent threat.

Whether or not the US military is brought directly into the fight against the cartels will become clearer in the weeks and months ahead. However, there is some evidence that the mere threat of US military intervention is hardening the stance of some countries in the region towards criminal groups.

The Mexican president, Claudia Sheinbaum, for instance, has said “her government will cooperate with the US to fight drug trafficking”. To avoid any unilateral military strike against cartels that might undermine Mexican sovereignty, Sheinbaum has deployed tens of thousands of national guard troops across the country to stem the flow of drugs towards the US.

Maduro has more recently also pledged to send 15,000 Venezuelan troops to the border with Colombia. And he thanked Colombia for sending 25,000 military personnel to the border to tackle “narco-terrorist gangs”. The Colombia-Venezuela border is porous and has long been a key transit point for drug traffickers and smugglers.

Further south, in Paraguay, there is official support for Trump’s anti-cartel policies. Taking a leaf from Washington’s rule book, the Paraguayan president, Santiago Peña Palacios, has designated the Cartel of the Suns a foreign terrorist organisation.

Elsewhere in Latin America, El Salvador’s leader, Nayib Bukele, has been a trusted ally of the US in its battle against drug cartels. Bukele has been successful in curbing the power and influence of MS-13, putting most of its members behind bars in the country’s high-security prison.

El Salvador is also incarcerating kingpins and criminals deported from the US. If the increasingly focused US pressure is successful, it may be just a matter of time before all countries in Latin America fall in line with Trump’s war on drug cartels.

Why menopause may be even tougher for autistic people – and what needs to change

Source: The Conversation – UK – By Aimee Grant, Senior Lecturer in Public Health and Wellcome Trust Career Development Fellow, Swansea University

When we first set out to explore autistic experiences of pregnancy, another topic kept surfacing in the personal accounts we recieved: menopause. Again and again, autistic people described how difficult this life stage had been and how little support they had received.

So we expanded our focus and our new review reveals a stark reality. Autistic people may face more severe menopause symptoms, struggle to access to care and are routinely dismissed by healthcare professionals.

Menopause technically only lasts one day, which marks 12 months since the person had their final menstrual period. But the menopause transition – including the years of perimenopause before and post-menopause after – is often a much longer and more disruptive phase of life.

Menopause typically occurs between the ages of 45 and 55, but it can happen earlier.

During the menopause transition, a range of symptoms are common. This includes changes affecting the urogenital system such as physical changes to the shape of genitals, vaginal dryness, urinary incontinence and pain during sex.

Other symptoms include hot flushes, night sweats, depression and changes to mood, memory and concentration. Some people have mild menopause symptoms, but for others they can be severe and extremely disruptive.

Our review

We pooled all of the research on autistic menopause which included evidence from eight studies. This small number of studies in itself demonstrates how much more research is needed to better understand autistic experiences of menopause. We also included evidence from publicly available blogs about autism and the menopause.

In our review, we found that most autistic people didn’t know what was happening to them when symptoms began. They hadn’t had access to information that spoke to their needs or experiences. Often, they couldn’t find any at all.

Many turned to online forums and peer support groups. These could be helpful, but they said they would have preferred information from a more trusted source, like a doctor or nurse.

We found that while the symptoms autistic people reported were similar to the general population, they sometimes experienced them more intensely.

Sensory sensitivities seemed to increase for some. This in turn sometimes led to more frequent and extreme meltdowns, which are moments of overwhelming distress where people might scream, cry, pace or physically remove themselves from a situation.

Fatigue was also a major issue. While it’s common for all menopausal people to be more fatigued, some autistic people found this change difficult to navigate. This became particularly challenging for those who mask their autism – that is, who consciously hide or manage their autistic traits to avoid negative reactions from others.

Many said that during menopause, masking became harder or even impossible. They felt more exhausted and more socially awkward than before.

Many described changing their day-to-day routines to reduce fatigue, including doing less to allow more time to rest. When this didn’t sufficiently control their symptoms, some decided to seek medical help. Those who didn’t try to get help often reported previous negative interactions with healthcare, so didn’t trust that they would get support.

Few people mentioned hormone replacement therapy (HRT), even though it’s the gold standard for managing menopause symptoms.

Autistic people’s experiences of periods are under-researched – here’s why that needs to change


Overall, we found autistic people received little support for menopause from the healthcare system. Almost all autistic people reported negative experiences.

That shouldn’t be acceptable, especially when we know that autistic people face worse health outcomes on almost every measure, including an increased risk of early death and higher rates of suicide.

Autism diagnoses in people who were assigned female at birth often happens later in life. This has been linked to increased masking. For many, diagnosis leads to periods of reflection on difficulties earlier in life.

That matters because this self reflection and changing identity can be life-changing, but only if professionals recognise the signs and support people to access both diagnostic and menopause-related care.

What needs to change

A rethink is needed on how to better support autistic people through menopause. Healthcare professionals need better training. Autism-specific information and resources must be co-designed with autistic people.

Peer support should be properly evaluated too. In our review, some people said they had found informal support groups incredibly helpful. But they were also unsure whether the information being shared was accurate.

Everyone isn’t ‘a little bit autistic’ – here’s why this notion is harmful


Peer support has been used in the NHS, including for breastfeeding. But peer support services don’t always get enough funding and support from health professionals, and services aren’t always designed in a way that means they can provide support that makes a difference.

Peer support shouldn’t be a cheap or tokenistic solution. For it to work, it needs proper investment.

There’s still so much we don’t know about how autistic people experience menopause and it remains an under-researched area. What we do know is that menopause has significant effects on health and wellbeing. The fact that menopause symptom severity may be higher for autistic people means that providing adequate support is essential.

Working together with your child’s new school can make their first weeks easier

Source: The Conversation – UK – By Poppy Gibson, Lecturer in Primary Education, The Open University

If your child is putting on their school uniform for the first few times, and learning their way from the school gate into their reception class, they’re going through what education researchers like me call a transition.

As we move through life, we undergo several key changes like this, both in education and in our adult lives. Key transitions in childhood include starting nursery, beginning school, and moving from primary to secondary school. As an adult, you may have been through many further transitions, such as starting a new job or moving into a new home.

But thinking of the start of school as one single event – one transition – doesn’t really capture the enormity of this new stage in your child’s life. A better perspective would be to expand the single word “transition” into the recognition of a number of multi-dimensional transitions, or changes, for both your child and for you. And thinking in this way may be helpful for both of you in coping with this change.

For children starting primary school, these multiple transitions may involve things such as a change in routine and their understanding of the world as they have to leave the house and travel to an unfamiliar place.

Their experience of food will be changing as they try new foods in their school, and perhaps have to eat with different rules than they have at home. Clothing changes, too. They may need to wear a uniform made of materials they haven’t felt before and that don’t feel comfortable or familiar.

Perhaps the biggest transition is being away from you for hours at a time. This is especially the case for those children who may not have attended a pre-school setting, or went to nursery part time. It is paramount, therefore, that transitions maximise the involvement of parents and carers.

Research has shown that transitional experiences have an effect on children’s attainment and wellbeing. Having a positive transitional experience can result in children developing positive attitudes, and they may learn valuable skills for embracing future change.

If we accept that transitions are multiple and have a ripple effect on a child’s life, we can take care to support all areas that will be affected. These include the child’s relationships, culture, routines, environment, perceptions and aspirations. This holistic understanding emphasises the importance of adopting collaborative approaches with children and families during transitional planning.

Fostering a purposeful partnership

The key to positive transitions is a strong partnership between home and school. Teacher-child and teacher-family relationships should be prioritised and nurtured. Having trust, respect and open channels of communication are the building blocks for future success.

It can be helpful to see the transitional period as your child begins school as the start of a purposeful partnership between you and your child’s teacher. You can meet as equal experts in your child’s welfare and support.

Teachers and support staff should welcome children in with the message: “We want you here; you belong here.” Teachers must be trusted for their professional knowledge, and well supported by their school to be lifelong learners where regular training is provided. Through mutual respect, teachers can offer care and the love of learning to help children develop both academically and socially.

It is perfectly normal if you feel nervous about your child starting a new school. Trust your judgment and knowledge of your child, and feel free to speak up when things do not seem to be going well, or if your child’s needs could be better met.

Parents need to be their child’s advocate, ready to communicate and share on the child’s behalf – especially as they may not fully be able to explain their own needs.

You could consider helping your child create a poster about themselves to give to their teacher. What do they love to do? Is it playing outdoors, or building with blocks? Do they have a favourite book or toy? Are there any things that scare your child or make them nervous? What are some things that make them feel better if they are upset?

Prioritising your child’s voice is crucial, and this could help their new teacher gain a quicker insight into who they are.

Eight seconds and dropping? How to make the most of short attention spans

Source: The Conversation – UK – By Barbara Jacquelyn Sahakian, Professor of Clinical Neuropsychology, University of Cambridge

We are regularly bombarded with information about a steep drop in attention spans. Based on its own data in 2015, Microsoft reported that the average attention span had dropped from about 12 seconds for millennials to eight seconds for gen Z.

And as the new Premier League season kicked off, UEFA introduced a new “eight seconds rule” stating a goalkeeper cannot hold the ball for more than eight seconds or the opposing team wins a corner kick. Coincidence? The rule was introduced to avoid time wasting. It may be that the mean length of attention needed to kick the ball is on average eight seconds. And perhaps this is also how long viewers can pay attention when nothing’s happening.

But how does attention really work? How can we improve it?

Attention is crucial. Who hasn’t experienced getting distracted in the middle of a conversation and suddenly forgot what they were saying. However, what is sometimes missed is that there are many forms of attention, and not all of them are necessarily diminishing.

The football rule is more closely related to a type of attention called visual scanning. For a goalkeeper, this can be scanning the field to work out who to pass the ball to. There are many studies on visual scanning in football, though not so much on goalkeepers.

One paper studied scanning and performance in English Premier League football players. They found using a ten-second scan time gave players a small but positive performance advantage.
Other studies have shown that within elite football players, the best players, spend more time scanning than others, unless there is an opponent player in close proximity.

Scanning is a form of attention that allows the footballer to take advantage of a time-limited opportunity, where decisions of who to pass to or where to run to on the field have to be made very rapidly.

This is a type of “hot cognition” – a social and emotional way of thinking, a bit like a gut instinct. It is very different to the “cold” or “rational” cognition involved in the decision making that footballers do with their managers and coaches off the field, where videos of plays are analysed.

In such situations, we are more likely to use “sustained attention”, which is paying attention to something for a sustained period of time. This ultimately requires mental concentration.

Similarly there are other forms of attention, for example “divided attention” or “alternating attention” which involve shifting attention between different things over a sustained period of time. These are typically also used for more cold decisions.

Different parts of the brain are at work when we use different kinds of attention. Hot decisions involve a brain network that includes the ventromedial prefrontal or orbitofrontal cortex, which support emotional regulation and decision making. Cold decisions, on the other hand, involves a different neural network that includes dorsolateral prefrontal cortex, supporting executive functions such as controlling or inhibitions or short-term memory.

Another time we make hot, rapid decisions is with first impressions. Again, the attention used is a type of immediate gut instinct. Unsurprisingly therefore, the dorsomedial prefrontal cortex is an important brain region associated with first impressions.

When we see or meet someone for the first time, we implicitly form an impression of their attractiveness and possibly other traits as well. We may adjust that initial immediate impression later, using more sustained or divided types of attention, as we learn more about the person.

A great example of this is given by Mr Darcy and Elizabeth Bennet in Jane Austen’s Pride and Prejudice, where negative first impressions form immediately. Only later are they corrected to positive impressions as more knowledge is gained about the two protagonists.

Positive first impressions tend to stick with people. Also, if very positive first impressions are accurate, they have been shown to lead long-term relationships, which in some cases may be the “love at first sight” effect.

Motivation improves attention

All this means there isn’t a single brain region involved in “attention” in general. It is possible to get better at one form of attention and worse at another.

For example, Gen Z has the highest daily screen time with many spending 2.5 hours per day on social media – which does require some sustained attention. The eight seconds is therefore more likely to be visual scanning or surfing for something interesting. Young people also spend long periods of time listening to podcasts and are increasingly consuming audiobooks, suggesting they can focus for long periods of time, but may prefer outlets that allow them to multitask. So, if the content is interesting, motivation can improve sustained attention.

I have been told several times by mothers of children and adolescents with attention deficit hyperactivity disorder (ADHD) that they don’t understand why their kids cannot concentrate on their schoolwork when they can spend hours playing computer games. The answer is motivation. When enjoying yourself, time goes by quickly and it is easy to sustain your attention over a long period of time.

This also suggests a solution to improving attention spans. We have to make tasks that require attention more motivating or fun.

Sustained attention

That said, it isn’t just scanning attention that appears to be reducing. There have been a number of studies on how sustained attention is decreasing too. Some psychologists therefore argue that lectures to students should be shorter.

However, a study of medical students found that information presented between 15 and 30 minutes was recalled best, whereas material presented during the first 15 min had the worst retention. So it is possible to hack people’s attention and design lectures in a way that makes them remember the content better?

Interestingly, where the student sat in the lecture hall also had impact on retention. Tests were given immediately following the lecture to students sitting at the front, middle, and back of the lecture hall. They remembered 80%, 71.6%, and 68.1%, respectively. However, where you chose to sit could also reflect your natural motivation for the lecture topic.

Biophysics researcher Neil Bradbury makes a compelling case that students’ motivation and teacher enthusiasm and passion, combined with good quality content and illustrations, are key factors in determining how long a lecturer is able to hold the audience’s attention. Perhaps allowing students to shift attention between listening, viewing and writing could also be useful.

Selecting the content should not be all about cold decision making, you also need to consider hot cognition in putting yourself in the minds of the audience and considering what might interest them the most.

Zack Polanski becomes Green party leader – what happens next?

Source: The Conversation – UK – By Louise Thompson, Senior Lecturer in Politics, University of Manchester

Zack Polanski is the new leader of the Green party in England and Wales after winning a leadership election promising a programme of “eco-populism”. Polanski beat incumbent leader Adrian Ramsay and his partner on the ticket, Ellie Chowns.

It’s been just over a year since the party celebrated its best ever results in the most recent general election. In July 2024, it doubled its vote share and quadrupled its representation in the House of Commons to four MPs.

The same election saw terrible results for the Conservatives and even for Labour, despite its win, raising questions about whether two-party politics was well and truly over. Since then, as professor John Curtice has vividly described, things have started to look even shakier.

This year’s local election saw a “record-breaking” fragmentation of the vote in which less than a quarter of local council seats went to the two main parties. The Greens now hold over 800 seats in more than 170 different councils, adding to their electoral portfolio – which also includes two members of the House of Lords and three London Assembly members.

While Polanski will be celebrating today, party members will look to him to raise their electoral fortunes even further. The electoral challenge for the Greens in England and Wales is two-pronged.

First, the party needs to maintain its position in the seats it has already secured. Its four MPs have fairly comfortable majorities, the smallest being Chowns’ 5,800 majority in North Herefordshire. Second, and perhaps most importantly, it needs to maximise its success in the 40 constituencies where it came second. All but one of these constituencies were won by Labour, which makes Labour voters the prime targets.

My research has shown how the Green party has followed a policy of “total engagement” in recent years. It takes its parliamentary work very seriously, using any and every opportunity to get its message across, even in lower-priority policy areas.

The goal here is to build credibility with the electorate. Small parties tend to want voters to think they are bigger than they are, so they can present themselves as realistic contenders for taking on the heavy work and responsibility of government. Caroline Lucas did a fantastic job of this, punching well above her weight as the party’s only MP between 2010 and 2024.

Together, the Green MPs have made over 380 contributions in the House of Commons. Chowns in particular has been a prolific backbencher, making 161 contributions, while the previous co-leaders Carla Denyer and Ramsay have been much quieter.

With Polanski sitting in the London Assembly rather than the House of Commons, this will inevitably change. The four Green MPs will collectively have more time on their hands and, with the right direction from their new leader, will have the space to be more strategic in their parliamentary activities.

Outsiders

But the Greens have always acted as something of an atypical party too, keeping one foot outside Westminster. Lucas was regularly involved in activism, joining protesters campaigning against tuition fee increases and fracking and to support refugees, to name just a few. She was even arrested in 2013 after joining a protest against energy firm Cuadrilla in Sussex (she was later cleared of all charges in court).

The new Green MPs have continued in this vein, with Sian Berry joining a peaceful protest against far-right agitators in Brighton last year and Chowns pressing the government to water down anti-protest laws.

The new leadership will need to decide whether this strategy enhances their electoral appeal. Does it highlight the Greens’ distinctiveness from the establishment parties, or does it imply they aren’t responsible enough to manage being a party of significant size? The answer depends on who you ask. Polanski has participated in several protests in the past, so chances are this activism will continue to be a core feature of Green party politics.

An added complication for the Greens is that two other parties are also chasing left-leaning voters. One of these is Reform UK. Although associated with rightwing views on social issues, the party came second in many Labour seats in 2024 and needs to appeal to both sides of the political spectrum.

This may explain why the Greens have focused their efforts on highlighting Reform’s failures. Berry, for instance, recently challenged Nigel Farage and his colleagues to publish a log of all their meetings since entering the Commons, arguing that it would be in the public interest.

The other outside threat is Jeremy Corbyn and Zarah Sultana’s new and currently nameless party of the left. While we know little about this party’s policy platform right now, it seems to be veering towards a similarly bottom-up democratic model of organisation which has long been favoured by the Greens – possibly even with co-leaders.

The challenge for the Greens will be to better establish their niche on the left, to ensure they capture voters who are disillusioned with Keir Starmer’s wobbly start. Part of the solution could be to focus on a handful of key policy areas which go beyond the Green party’s niche of environmental issues. At the moment, its MPs take something of a scattergun approach in the Commons, contributing on everything from local buses and universal credit to Ukraine and the Middle East.

Some of the most recent questions asked during Prime Minister’s Questions by Greens hint at the options they might pursue. Ramsay has pushed for a wealth tax on the super rich, and an end to the two-child benefit cap. Both Corbyn and Sultana have, of course, been outspoken on these issues in the past.

If the Greens can’t forge a different path to this new left party, they may have no choice but to consider an electoral pact to avoid splitting the anti-Labour vote right down the middle.

À la ménopause, savez-vous que le risque cardiovasculaire augmente ? L’activité physique peut aider

Source: The Conversation – France in French (3) – By Carina Enea, Maitresse de Conférences en physiologie de l’exercice – Faculté des Sciences du Sport, Université de Poitiers

La ménopause représente une période critique à partir de laquelle le risque cardiovasculaire (AVC, infarctus du myocarde…) augmente. Mais beaucoup de femmes l’ignorent. En prévention, une activité physique régulière peut se révéler bénéfique.


En France, les maladies cardiovasculaires représentent la première cause de mortalité chez les femmes, bien loin devant le cancer du sein.

Chaque année, elles emportent plus de 75 000 femmes, les décès par accidents vasculaires cérébraux (AVC) étant les plus fréquents. Pourtant, ces risques demeurent largement sous-estimés, tant par les femmes elles-mêmes que par une partie du corps médical.

L’une des périodes les plus critiques dans l’évolution du risque cardiovasculaire chez les femmes est la périménopause (période pendant laquelle les règles commencent à devenir irrégulières), ainsi que les années qui suivent la ménopause (arrêt des règles depuis plus de douze mois) et que l’on nomme « postménopause ».

Périménopause et postménopause, fenêtres de vulnérabilité cardiométabolique majeure

Trop souvent réduites à leurs symptômes les plus connus (bouffées de chaleur, troubles du sommeil, irritabilité), ces périodes sont en réalité des fenêtres de vulnérabilité cardiométabolique majeure pour les femmes.

En effet, les œstrogènes (hormones principalement produites par les ovaires) ont un effet protecteur sur le système cardiovasculaire et leur déclin progressif dès la périménopause impacte directement la santé cardiovasculaire. Conséquence : la pression artérielle tend à s’élever, le profil lipidique se détériore, la résistance à l’insuline (une hormone impliquée dans la régulation de la glycémie, ndlr) augmente, et la graisse abdominale s’installe plus facilement.

Autant de changements défavorables qui augmentent à moyen terme le risque d’événements cardiovasculaires chez les femmes.

Malgré l’importance du sujet, les femmes restent encore aujourd’hui sous-représentées dans les études cliniques portant sur les maladies cardiovasculaires et cérébrovasculaires. Ainsi, selon une étude récente publiée dans la revue scientifique Neurology, les femmes ne représentent qu’un tiers des participants dans les essais cliniques sur les AVC, ce qui limite la compréhension de cette pathologie chez elles et l’efficacité des stratégies de prévention et de traitement.

Le dispositif « Mon bilan prévention » à partir de 45 ans

La prévention du risque cardiovasculaire chez les femmes reste encore trop souvent tardive, alors que la ménopause devrait constituer un moment clé pour effectuer un bilan de santé global.

Ce besoin a, d’ailleurs, été souligné dans le Plan interministériel pour l’égalité entre les femmes et les hommes 2023-2027 qui intègre, pour la première fois, un objectif spécifique de prévention cardiovasculaire féminine, notamment à travers l’initiative « Mon bilan prévention ». Ce dispositif, destiné aux femmes à partir de 45 ans, viserait à détecter précocement les facteurs de risque cardiovasculaire, en tenant compte des spécificités liées au sexe et à l’âge.

C’est également une des propositions phares du rapport de la mission parlementaire sur la ménopause en France, publié en avril 2025, qui recommande explicitement d’inscrire la ménopause comme un moment stratégique pour renforcer la prévention cardiométabolique chez les femmes.

Des outils conçus pour les hommes, qui sous-évaluent le risque des femmes

Néanmoins, les outils actuellement utilisés pour estimer le risque cardiovasculaire reposent majoritairement sur des cohortes masculines. Ils ne prennent pas suffisamment en compte des facteurs spécifiques aux femmes, tels que la ménopause précoce, les symptômes vasomoteurs sévères (bouffées de chaleur, sueurs nocturnes), ou encore certains antécédents obstétricaux (prééclampsie, diabète gestationnel) ou gynécologiques (endométriose, syndrome des ovaires polykystiques).

Plus grave, les femmes sont plus sensibles que les hommes à plusieurs facteurs de risque traditionnels, comme l’hypertension artérielle, le diabète ou le tabagisme. Ces biais de conception des outils d’évaluation mènent à une sous-estimation du risque réel chez les femmes, ce qui peut entraîner des retards de diagnostic et de prise en charge.

Une récente initiative française, les « Bus du cœur des femmes », a d’ailleurs proposé un dépistage gratuit auprès de 4 300 femmes (âge médian : 54 ans), issues de 20 villes françaises, en prenant en compte ces différents facteurs de risque.

Les données récoltées montrent que plus de 70 % d’entre elles n’avaient jamais eu de consultation de prévention du risque cardiovasculaire au préalable, alors que 90,2 % présentaient au moins deux facteurs de risque cardiométabolique et 48,9 % des antécédents obstétricaux et/ou gynécologiques.

L’exercice physique : une intervention non médicamenteuse aux multiples bénéfices

En prévention, l’activité physique régulière peut se révéler extrêmement précieuse si elle est pratiquée conformément aux recommandations (cf. l’infographie de l’Observatoire national de l’activité physique et de la sédentarité [Onaps], ci-dessous).

Ses bénéfices sont multiples : amélioration de la composition corporelle (augmentation de la masse musculaire, réduction de la graisse abdominale), optimisation du profil lipidique sanguin, diminution de l’inflammation chronique de bas grade (mécanisme physiopathologique intracellulaire qui se développe à bas bruit, ndlr) et soutien à la santé mentale, notamment par la réduction des symptômes anxieux et dépressifs.

Nos travaux de recherche ont ainsi montré que les femmes ménopausées très actives physiquement n’ont pas de marqueurs de santé cardiométabolique altérés, contrairement à ce qui est généralement observé chez les femmes inactives (qui ne respectent pas les recommandations). Par ailleurs, certaines études suggèrent que l’activité physique régulière pourrait également atténuer les symptômes vasomoteurs, tels que les bouffées de chaleur ou les sueurs nocturnes, bien que ces effets restent à confirmer par des recherches complémentaires.

Les bénéfices du renforcement musculaire

Au sein du laboratoire Mobilité, vieillissement et exercice, nous avons également cherché à déterminer les modalités d’exercice les plus efficaces pour préserver la santé cardiovasculaire et les performances cognitives. Nos résultats indiquent que les exercices de renforcement musculaire, comme le gainage, la méthode Pilates ou les séances de type cuisses-abdos-fessiers, s’avèrent particulièrement bénéfiques pour la régulation de la pression artérielle, plus encore que les activités (dites « d’endurance ») qui sollicitent davantage le système cardiorespiratoire, comme la course à pied ou le vélo.

Les exercices de renforcement musculaire permettent notamment une réduction significative de la pression artérielle nocturne, un facteur de protection reconnu contre les événements cardiovasculaires.

Sur le plan cognitif, si l’effet immédiat de l’exercice sur les performances est relativement limité, nos données révèlent une augmentation de l’oxygénation du cortex préfrontal, une région clé pour la mémoire, l’attention et les fonctions exécutives. Cet effet est d’autant plus marqué chez les femmes présentant une bonne condition cardiorespiratoire, ce qui souligne l’importance d’un entraînement régulier et bien ciblé pour préserver la santé cérébrale à cette étape de la vie.

Ainsi, chez les femmes très actives (c’est-à-dire qui dépassent les recommandations), la ménopause ne s’accompagne pas d’une baisse des performances cognitives globales.

Prendre en compte les symptômes pour mieux prescrire l’activité physique

Autre enseignement important de ces études : les femmes présentant des symptômes vasomoteurs modérés à sévères tireraient un bénéfice accru de l’activité physique et notamment des exercices de renforcement musculaire. En effet, leur pression artérielle nocturne baisse de façon plus marquée après ce type d’exercices.

De plus, ces femmes ont tendance à moins pratiquer d’activité physique de loisir que celles dont les symptômes sont légers ou absents, un constat qui renforce la nécessité d’un accompagnement ciblé.

Vers une médecine préventive adaptée aux femmes

Nos résultats soulignent l’importance de repenser la prévention cardiovasculaire chez les femmes à la ménopause : elle ne peut plus se limiter à des messages généraux. Il s’agit d’intégrer pleinement l’activité physique comme un outil thérapeutique à part entière, avec une prescription adaptée au statut hormonal, mais également au profil symptomatique de chaque femme.

La ménopause ne devrait plus être considérée comme une étape dite « hormonale », mais comme une chance unique de prévention et de dépistage du risque cardiovasculaire des femmes.

L’exercice physique, simple, efficace et accessible, pourrait en être le pilier.

Donald Trump was once India’s best friend. How did it all go wrong?

Source: The Conversation – Global Perspectives – By Ian Hall, Professor of International Relations, Griffith University

Just months into President Donald Trump’s second term in office, one of the United States’ most important strategic partnerships is in crisis.

Relations between the US and India are at their lowest ebb in a quarter of a century. Things are so bad that Indian Prime Minister Narendra Modi has reportedly refused to accept calls from Trump for more than two months.

In recent days, Trump labelled trade ties with India a “totally one-sided disaster” and a report emerged that he is no longer planning to visit India later this year for a summit of the Quad partners (India, the US, Australia and Japan).

So bad, so quickly

Things were not meant to happen this way. Many in New Delhi were delighted when Trump won the election last year. Modi congratulated his “friend” on X, along with pictures of the two embracing and holding hands.

India’s foreign minister, S. Jaishankar, told journalists that while other countries might be “nervous” about Trump’s return, India was not.

Feeling confident, Modi went to Washington to meet Trump days after his return to office. The encounter did not go well.

On the eve of the meeting, Modi was embarrassed by distressing images of Indian nationals, handcuffed and shackled, being deported from the US on a military aircraft.

In the Oval Office, he promised to buy more US arms, oil and gas, and asked that Trump not impose punitive tariffs on India. Modi failed to get that commitment.

A few weeks later, Trump announced India would be hit with a 27% tariff – far higher than the 10% imposed on China – unless it could negotiate something better.

Crisis in Kashmir

Begrudgingly, New Delhi began to talk trade. US Vice President JD Vance visited India in late April and both sides made positive noises about a deal. But while Vance was in town, India was engulfed in a new crisis.

On April 22, terrorists killed 26 people – mostly Hindu tourists – in Kashmir, long the site of simmering conflict between India and Pakistan. The Modi government pledged to respond with force, as it had done in the past after similar incidents.

On May 7, India bombed what it claimed were militant camps in Pakistan and Pakistan-administered Kashmir. A rapidly escalating, unpredictable conflict followed, as both sides used drones and missiles to attack one another.

Alarmed, governments around the world urged the two nuclear-armed states to end hostilities before matters got out of control. Early in the morning on May 10, they did, and agreed to a ceasefire.

Trump anoints himself peacemaker

Before either the Indian or Pakistani governments had a chance to say anything, Trump stepped in to take credit.

On social media, he announced both sides had agreed a deal. The next day he claimed they would soon sit down with him as mediator and find a solution to the Kashmir conflict.

Islamabad was jubilant at this outcome. New Delhi, meanwhile, was furious.

India’s longstanding view is that the Kashmir dispute must be settled bilaterally, without third-party involvement. The US has accepted this position for more than 20 years. Now it appeared Trump was taking a different view.

This put Modi in a bind. Keen to maintain a mutually beneficial partnership and avoid punitive tariffs, he did not wish to upset Trump.

But he could not acknowledge Trump’s claims without setting aside a fundamental principle of Indian policy. So, Modi called Washington and explained he would not accept mediation over Kashmir.

The final straw

Meanwhile, Pakistan saw an opportunity to win favour in Washington and drive a wedge between the US and India.

Recognising that Trump covets a Nobel Peace Prize, Islamabad nominated him for his supposed role in ending the conflict.

Enthused, Trump called Modi on June 17 and asked him to do the same. Worse still, Trump requested Modi stop in Washington on the way back from the G7 summit in Canada, and meet with Pakistan’s military chief, Asim Munir.

According to a recent report, that was the final straw for Modi. He flatly refused both requests. The two men reportedly haven’t spoken since.

Piqued, Trump responded by punishing India for continuing to buy Russian oil by lifting its tariff rate to 50% and postponing trade talks.

New Delhi’s dilemma

Trump’s actions have ordinary Indians seething and demanding action, but the Modi government does not have good options.

Giving in to coercion would make Modi – dubbed by political opponents “Narender Surrender” – look weak. Yet, no other major power can offer India what it needs in terms of markets, investment, technology, weapons and diplomatic support.

With US-India relations strained, New Delhi has been working hard to stabilise its relationship with China, which has been tense since bloody border clashes between the two in 2020.

Modi went to China for the first time in seven years on August 31 to further that aim, shaking hands with President Xi Jinping. But although Xi emphasised the need for amicable ties – he said the “elephant and dragon should dance together” – there is little trust between India and China at present.

Modi has more faith in Russia. In China, Modi and Russian President Vladimir Putin reportedly spoke for nearly an hour in Putin’s limousine. And Modi will host the Russian leader for more talks in India later this year. However, Russia remains a pariah in Europe, with limited means to help.

Other countries, like Japan, where Modi stopped off on his way to China, could also help India navigate the current crisis. But they do not have the clout to resolve it.

Unless Modi can find a way to win Trump back, India’s next few years could be very difficult.

Trump’s tariffs are headed to the US Supreme Court, prolonging the chaos on trade

Source: The Conversation – Global Perspectives – By Felicity Deane, Professor of Trade Law and Taxation, Queensland University of Technology

Trading partners of the United States are facing a fresh period of uncertainty after a US federal appeals court ruled President Donald Trump’s “reciprocal” tariffs were illegal.

In a 7-4 majority, the judges ruled Trump had exceeded his power by invoking emergency powers to impose tariffs of “unlimited duration on nearly all goods from nearly every country in the world”, upholding an earlier court decision.

The ruling will throw into disarray the strategies of trading partners still in negotiations with the US, who may decide to wait and see the outcome of the legal battle.

Although there are different options available to challenge the decision, Trump has made it clear the next stop will be the Supreme Court.

The US Court of Appeals for the Federal Circuit said the tariffs would remain in place until October 14, to allow time for further appeals.

The power to tax rests with Congress

The ruling tested the limits of executive power under the International Emergency Economic Powers Act (IEEPA) from 1977. Trump is the first president to use this act to impose tariffs, setting the stage for a test of executive power. At least for now, it is a test the administration appears to have failed. The judges rejected Trump’s interpretation, which they said would place no limit on the president to raise revenue without any authorisation from Congress.

Citing Article 1, section 8, of the US Constitution, the majority judgement unequivocally stated that “tariffs are a tax” and the power to tax under the Constitution rests with Congress.

In upholding an earlier decision by the Court of International Trade, the appeals court majority noted:

if the President can declare an emergency to cut the deficit by raising taxes in whatever way he wishes, not much remains of Congressional authority over taxation.

The tariffs are still in place

There were two important outcomes from this latest decision. First, the “liberation day” tariffs are (currently) deemed illegal. Second, these “illegal” tariffs will temporarily stay in place to allow for the appeal options to be explored.

Revenue will continue to be collected under the executive orders in question. Should the tariffs be deemed illegal on appeal, that revenue may need to be returned.

This ruling does not apply to all tariffs. It doesn’t cover specific sector tariffs such as those on aluminium and steel. However, other tariffs imposed during the first Trump presidency have already been ruled illegal under World Trade Organization rules and are currently the subject of appeal under the multilateral dispute settlement system.

The latest ruling would not reverse the decision to suspend the de minimis exception that caused global postage chaos. However, if the ruling is upheld, the rate of tariffs on low-value goods would revert back to pre-“liberation day” percentages. In many instances, this would mean back to zero.

What about the deals?

Trading partners initially responded with panic to the unveiling of Trump’s chaotic tariff agenda in April. There was a rush to meet with the president and make so-called deals. So what should governments of trading partners do now?

The most logical response might be to wait out the US legal process, because there may be no point in making deals if the tariffs are upheld to be illegal.

Unfortunately, this means continued uncertainty for business. On one hand, the courts may determine the tariffs are unlawful and must therefore be revoked. But Congress could subsequently move to reimpose tariffs with fresh legislation, or Trump could try other legal avenues.

The Constitution vs loyalty to Trump

If the administration does decide to appeal to the Supreme Court, the important test will not necessarily be about tariffs but whether the US Constitution will continue to support the separation of powers.

The appeals court decision argues the IEEPA does not support the introduction of tariffs of the magnitude of the “liberation day” tariffs. What the IEEPA does allow is for the president to “regulate […] importation”. However, the court suggested this phrase is nothing more than

a wafer-thin reed on which to rest such sweeping power.

Although the appeals court noted that such arguments have been rejected by the Supreme Court in the past, we will have to wait and see whether it is a “wafer-thin reed” that will become doctrine.

The Supreme Court has a conservative majority, with six of nine judges appointed by Republicans, including three in Trump’s first term.

The Supreme Court has already granted the president immunity from prosecution in some circumstances. If the majority decides to allow these widespread and indefinite tariffs, they may be one step closer to creating an American monarch.

China may not invade Taiwan, but rather blockade it. How would this work, and could it be effective?

Source: The Conversation – Global Perspectives – By Claudio Bozzi, Lecturer in Law, Deakin University

US officials believe Chinese President Xi Xinping has set a deadline for his military to be capable of invading Taiwan by 2027 – the centennial anniversary of the founding of the People’s Liberation Army (PLA).

US Secretary of Defense Pete Hegseth mentioned this date at a security conference in Singapore in May, warning of the “imminent threat” China poses to Taiwan.

The PLA has invested heavily in expanding and modernising its operations in recent years. Since 2015, it has built the world’s largest navy and coast guard.

But rather than threaten an invasion of Taiwan, China seems increasingly likely to pressure the self-governing, democratically ruled island with an extended blockade to force it to capitulate.

In preparation for such a possible action, China has developed a new command structure enabling it to coordinate its air, sea and land-based weapons systems to enact a strategy of lianhe fengkong (联合封控), or joint blockade. This would effectively cut Taiwan off from the outside world.

In late July, the Centre for Strategic and International Studies (CSIS) produced a report on 26 simulated war games it conducted to determine what a Chinese blockade of Taiwan would look like.

Taiwan’s natural gas supplies were predicted to run out after ten days of a blockade. Coal and oil supplies would run out in a matter of weeks. If Taiwan’s electricity was reduced to 20% of its pre-blockade levels, all manufacturing would cease. Casualties were expected to be in the thousands.

Taiwan is particularly vulnerable to a blockade. It relies more than any other developed nation on port calls relative to the size of its economy. Its biggest ports are on its west coast, facing mainland China. The island also has limited emergency food and fuel reserves.



What is a blockade under the law?

Imposing a naval blockade during armed conflict is an established right under customary international law. Blockades are not illegal per se, but they must comply with the laws of war. It’s a complicated and controversial area of the law.

To be legal, a blockade must first be effective. That is, the blockading power must maintain a force that prevents access to the enemy’s coast.

Other nations must be notified of the instigation of the blockade and its geographical extent.

A blockade must be enforced impartially against all vessels, except neutral vessels in distress. Any vessel breaching the blockade would be subject to being stopped, captured or fired upon.

Lastly, a blockade cannot prevent access to neutral ports or the delivery of humanitarian assistance to civilians.

Blockade strategies

China may use one of several blockade strategies against Taiwan. In contrast to an invasion, blockades can be scaled up or back, or reversed, depending on the unfolding security situation.

For instance, China may attack merchant shipping vessels seeking to enter Taiwanese waters to deliver essential cargo, coercing Taiwan to submit to China’s takeover. This is known as a kinetic blockade.

Alternatively, it may implement its preferred strategy of “winning without fighting”. Given the sheer size of its navy, coastguard and maritime militia, China could simply encircle the island and block access to its ports.

This could isolate Taiwan from the global economy to the point of forcing it to surrender, or weaken it sufficiently to enable an invasion, without engaging in open hostilities. This is a non-kinetic blockade.

Other ways of impeding naval passage

China may also use measures that fall short of a blockade, but have similar effects. It has passed a suite of domestic laws that legitimise military and non-military aggression of this kind.

For example, the navy or coast guard may:

  • lay mines in the sea without declaring a formal blockade
  • establish maritime danger or exclusion zones for foreign ships, and
  • intercept, detain and regulate foreign vessels.

These tactics would only be effective because China’s domestic laws have exploited ambiguities in jurisdiction over its surrounding waters.

For example, China has passed laws requiring notification from foreign vessels if they enter waters it considers its own and under its control, and allowing its ships to alter or suspend maritime traffic for security or military purposes.

Those powers, however, are inconsistent with international law. China, for example, considers the Taiwan Strait as Chinese territory. Under the UN Convention on the Law of the Sea, however, the strait is considered international waters, which enables freedom of navigation for all vessels.

Also, creating an unstable security environment around Taiwan (similar to what Houthi forces have done in the Red Sea), or threatening penalties and sanctions for failing to comply, may in effect be tantamount to a blockade.

How to counter a blockade

It is not clear how other nations would respond to a Chinese invasion or blockade.

In recent years, China has attempted to project its naval power by establishing no-go zones in its neighbourhood, such as turning the South China Sea into its own fortified waters.

One way to oppose China, then, would be a counter-blockade. This would entail allied naval forces, likely led by the United States, closing the choke points, such as the Malacca Strait, on which Chinese seaborne trade with global markets depends.

However, counter-blockades are problematic, too. The impact on the world economy would be huge, as a blockade of the Malacca Strait, for example, could impact all trade between Asia and the rest of the world. China has also stockpiled domestic resources and expanded its land-based trade routes in recent years.

The best option, then, might be supporting Taiwan to survive a long blockade, forcing China to back down.

This means helping Taiwan become more resilient by increasing its food, fuel and medicine stockpiles, developing robust communication and cyber defences, and strengthening its port and energy infrastructure.

If the US built up its naval capacity in the Pacific, it could also use frigates to escort convoys of merchant ships to break a Chinese blockade, though the CSIS war games indicated this could come at a considerable cost of lives and ships – and increase the potential for all-out war.
