Millions will get a windfall over car finance. Research helps us understand what they’ll do with it

Millions of motorists across the UK could be in line for payments of around £700 after car dealers mis-sold finance to earn commission. Finance providers stand to lose billions compensating consumers after the scandal.

The UK regulator, the Financial Conduct Authority (FCA), recently announced that lenders must compensate buyers who took out finance for a new or secondhand car. Millions paid more than they should have because of secret fees paid by lenders to dealerships.

For many, this compensation will be a welcome surprise. For others, it will be hard-won compensation after a complicated legal battle. For others still, £700 may not be enough compensation for the time and stress involved – the sum is lower than the FCA had previously estimated – although the total paid out could top £8 billion.

This settlement begs an interesting question. What should recipients do with this money? This is hardly a trivial question. Organisations such as the National Lottery provide financial advice to big winners, recognising that a windfall involves a lot more than popping the champagne corks.

However, financial advice after winning the lottery – pay off debts, buy a house, invest in long-term assets – does not apply to the relatively small sum of £700. But neither is it smart to write off £700 as if it were only a small win. Economically speaking too, a spending boost of up to £8 billion would show up in UK GDP figures.

Behavioural economists have found that people’s decisions about money depend on their mental frame of reference. If they feel like they’ve lost money, their decisions to save or spend will be quite different to if they feel they’ve gained something. Precisely because many people will have already written off the costs of mis-selling, it is likely that they will choose to spend their compensation.

The psychology of winning can be pernicious because of what economists call “licensing” effects. Licensing happens when a previous event or behaviour influences future actions. If you’ve gone to the gym in the morning, you might choose to have a dessert in the evening – but only because you went to the gym.

Likewise, if you “win” £700 you had mentally written off, you will be more inclined to buy things you would otherwise avoid. In this mental state, small luxuries like eating out or buying designer shoes are likely to feel more tempting. Very quickly, that £700 could disappear.

Spending money is not a bad thing. It is only through spending that the economy grows, which to a lesser or greater extent benefits everyone. And using the money to invest in a new hobby, for instance, is likely to be personally rewarding in ways a cold financial outlook fails to appreciate.

But there is also a more sympathetic, and less explored perspective. Someone might understand what they ought to do financially, but reasonably decide that £700 is not worth the effort. For example, earning 3% on £700 means next year you’d be £21 richer, ignoring inflation. From this perspective, it is reasonable – if not economically rational – to decide spending is preferable to saving.

A growing issue

The question of how to use a windfall is fascinating because it’s an example of something economies like the UK are going to see a lot more of in the coming decades. The movement of wealth from retirees to their adult children (those aged around 30 to 50) has been called the greatest wealth transfer in human history.

It’s not going to be an even transfer. Some millennials will receive enormous sums as their parents pass on houses and savings pots. Others will receive very little. But a large group will receive something in the middle – an unexpected windfall, too large to write off but too small to lay down new financial roots by buying a house, for example.

In the years ahead, what this group does with its slice of a generational inheritance will shape the financial landscape of the UK, and many more countries, too.

This £700 settlement is therefore an interesting example. While people may feel they know what they ought to do with unexpected money, behavioural economics can tell us what people probably will do.

The “ought” depends on someone’s financial circumstances. For those set to receive £700, it might be a good idea not to treat it as a windfall. They had probably mentally written it off, so if they avoid seeing it as a gain they are more likely to pay off debts or save it.

Payments could start coming through from early next year. With that in mind, another sensible place for many to “invest” £700 might be in credit with their energy supplier. This could smooth out financial bumps in the road, given rising energy costs.

Many people dislike saving because it can feel like losing money, as they are moving the funds from a “fungible mental account” – where they can do anything with it – to a “non-fungible mental account” (such as a rainy-day fund).

For economists, examples like a £700 compensation are fascinating because they expose elements of human behaviour that we are all guilty of.

But this compensation scheme is also likely to be a precursor to a much bigger economic phenomenon. What will people do when they suddenly receive a sum that’s too big to ignore but too little to change their financial foundations?

Should parents allow their children to go online? All the inflammatory coverage makes the decision far harder

Source: The Conversation – UK – By Phil Wilkinson, Principal Academic in Communications, Bournemouth University

Damned if you do … Studio Romantic

Young teenagers on TikTok can easily access hardcore porn content, a new study has found.

By creating fake accounts for 13-year-olds, researchers at the non-governmental organisation Global Witness were quickly offered highly sexualised search terms. Despite setting the app to “restrictive mode”, the researchers were able to click through to videos showing everything from women flashing to penetrative sex.

Most of these videos had been created in such a way that they were designed to evade discovery, and TikTok has moved swiftly to take them down.

But the fact that they were easy to find is a fresh blow to the UK Online Safety Act. The act, which came into force over the summer, requires tech companies to prevent children from being able to access pornography and other harmful content.

There have already been reports that Meta’s efforts to make Instagram safer for young people are similarly ineffective.

There are also concerns about a surge in VPN downloads and traffic to pirate sites by users aiming to get around the restrictions in the act. Some are now calling for VPNs to be banned, though that seems unlikely.

It would be easy for parents reading these reports to conclude that there is nothing that can be done to make the internet safe for their children. Many will increasingly be tempted to ban access outright rather than try to navigate the risks in a more measured way.

Certainly, the act was introduced for good reason. According to research published in 2025, one in 12 children were being exposed to online sexual exploitation or abuse. An EU report from 2021 that surveyed more than 6,000 children also found that 45% reported they had seen violent content and 49% had encountered cyberbullying.

Yet there is a danger in downplaying progress. Since the act was introduced, most of the top 100 adult sites have introduced age checks or blocked UK access – and so have sites that allow pornographic content such as X and Reddit.

It wouldn’t be the first time that media coverage has over-focused on the online risks to children. Take Roblox, for instance. Launched in 2006, it’s a “virtual universe” that allows users to create their own content. As of 2025 it has over 85 million daily active users, of which 39% are below the age of 13.

The site has come in for heavy criticism for incentivising harmful content by rewarding creators for attracting high engagement from other users, while lacking adequate content moderation to prevent violations of the rules.

This has exposed children to undesirable things such as Nazi roleplaying games and sexual content. One much-quoted report published in 2024 even declared it an “X-rated paedophile hellscape”.

True enough, children can potentially be exposed to harmful content on the platform – as with any platform of user-generated content. But a paedophile hellscape? It’s worth reflecting that Roblox is also being studied by researchers for its ability to help young people learn and explore their identities in more wholesome ways (it also introduced extra safeguards for children a few months ago).

To stress, there are online risks parents need to contend with, but the way these risks are reported does not help. TikTok, for instance, has been in trouble over its content before. In 2022, research by the Centre for Countering Digital Hate concluded that children can be exposed to harmful content every 39 seconds – with one newspaper turning this into a headline about TikTok’s “thermonuclear algorithm”.

Given that some parents already lack confidence in managing digital technology, this kind of sensationalist language doesn’t help. This 2024 study points to the “joy, connection and creativity” that children also experience on the platform.

We’ve been here before

In truth, we’ve been hearing about the technological threat to children for a very long time. The 1935 New York study, Radio and the Child, argued that radio presented a new insidious threat as it encroached into the family home and children’s bedrooms: “No locks would keep this intruder out, nor can parents shift their children away from it.”

A 1941 study from San Francisco, Children’s Reactions to Movie Horrors and Radio Crime, called the technology a “habit-forming practice very difficult to overcome, no matter how the aftereffects are dreaded”.

A few years later, television had become the focus of parental fears. According to the 1962 BBC Handbook: “Nobody can afford to ignore the dangers of corruption by television through violence or through triviality, especially the young.”

Soon came the 1964 Television Act, which introduced the 9pm watershed. It prevented broadcasters from showing programmes unsuitable for children before that time, which seems quaint next to today’s concerns.

The clear pattern is that one generation’s moral panic becomes a source of amusement to the next one as they focus on a new threat. Time and again, the coverage is so distorted and inflamed that it makes parents feel more anxious and estranged. This makes managing the actual risks much more difficult.

The negotiated alternative

The reality is that restrictive approaches by parents can be counterproductive, especially as they may encourage children to be evasive. Children’s instincts, according to the research, are to talk about potentially harmful material with their parents, but they’re less likely to do so if parents take a hard line since it makes them fear they’ll be judged. In other words, they’ve become more likely to consume harmful content as a result.

The alternative is for parents to adopt a strategy of negotiated decision-making with their children. Instead of viewing online material as alien or inherently negative, it becomes proactively integrated into family life. One researcher described it as “living out family values through technology”. It becomes about accepting risk with a view to building children’s resilience.

Negotiation helps.

Unfortunately this sits uncomfortably with the current rhetoric around the internet, since it’s recommending moderated, negotiated exposure to something “thermonuclear”. Compounding this is the abundance of digital pundits offering reactionary and unworkably prescriptive advice. Any parent who deviates from the “recommended” screen-time for their children runs a risk of judgement, treating technology as a “digital pacifier”.

Just like the watershed before it, the Online Safety Act mitigates risks but won’t remove them altogether. It is ultimately still on parents to decide how to deal with them in accordance with their family values. The more the reporting around this area is endlessly negative, the more difficult that becomes.

The UK military says Russia targets its satellites on a weekly basis. What can be done about it?

Russia is targeting UK space infrastructure, and in particular military satellites, on a weekly basis, according to the head of UK Space Command.

In an interview with the BBC, Maj Gen Paul Tedman said that Russia was “shadowing” UK satellites. Shadowing involves orbiting and aligning a satellite close to the target satellite, in order to be near enough to jam communications or intercept signals to steal critical information.

Tedman said Russia’s satellites had “payloads on board that can see our satellites and are trying to collect information from them”. He also confirmed that jamming of UK military satellites was taking place.

This involves broadcasting signals on the same frequencies as those used by satellites, in order to intentionally disrupt or overwhelm legitimate signals. It does not physically damage spacecraft, so as soon as the jamming signal is no longer being emitted, communications can be restored. The jamming of satellite signals can take place from the ground, ocean or air, as well as from space.

But what about other tactics that could be used to disrupt satellites? One thing not mentioned in relation to the attacks on British military satellites, is the use of lasers. These can be deployed to dazzle satellites’ onboard optical sensors. This can interfere with electronic circuity but would not cause lasting physical damage.

The most serious type of attack of course would be the use of a direct-ascent missile, which can be launched from the ground, sea or air, to destroy an orbiting satellite. Previous tests of this kind of anti-satellite (Asat) weapon have generated worrying levels of orbiting debris. This debris can then collide with other satellites, potentially generating even more debris for other space-based assets to avoid.

On February 24, 2022, the day of Russia’s invasion of Ukraine, satellite broadband users across Europe got a taste of the kind of attacks that the military is now used to. A cyber-attack was launched against Viasat’s Ka-Sat satellite network, which supplies internet access to tens of thousands of people across Ukraine and the rest of Europe. Experts said they believed the purpose of the attack was to interrupt service rather than to access data or systems.

A recent talk by German IT researchers also revealed how much damage hackers could potentially do if given unfettered access to a satellite’s onboard systems. The experts said that attackers could exploit vulnerabilities in open source software used by Nasa and Airbus to control satellites. This in turn could give the intruders access to the control functions on a satellite, allowing them to change its orbit by sending a command to fire its thrusters.

Attacks don’t need to target the satellite directly. Targeting control stations on the ground can also disrupt operation of the satellites in orbit. This can also have consequences for end users of a satellite service.

Wider problem

It’s not just the UK’s satellites that are being targeted, however. In September, the head of French space command Maj Gen Vincent Chusseau said there had been a spike in hostile activity in space. Chusseau said activity had increased since Russia’s full-scale invasion of Ukraine in 2022.

He said that adversaries, especially Russia, have diversified methods of disrupting satellites and that jamming, lasers and cyber-attacks have become commonplace.

The same month, Brig Gen Christopher Horner, commander of 3 Canadian Space Division told a space security summit that there were more than 200 anti-satellite weapons orbiting Earth.

While he didn’t provide details on their nature, he said it was a “shocking number” to threaten allied satellites.

Increased investment

It’s possible to satellites by improving the encryption of data transmitted to them as well as with anti-jamming technology. This uses a variety of techniques to block out or nullify the signals used by jammers to interfere with satellite communications. It’s also important to ensure there are alternative providers for critical space services as a backup in case of attack.

In response to increasing threats to UK satellite infrastructure, the UK government has recently increased its investment in projects geared towards space security. The government has invested £500,000 in a project to develop sensors that counter lasers used to blind satellites. The UK has also recently developed Borealis, a software platform designed to monitor and protect critical UK and allied satellites.

As well as investing in its own projects, the UK has also sought to improve space-based security by strengthening international partnerships. For instance, the UK recently invested €163 million (£141 million) in Eutelsat, which provides satellite internet and is a rival to Elon Musk’s Starlink system.

Starlink’s importance not only for consumers, but also for military applications has been demonstrated in the Ukraine war – where Ukrainian troops had come to rely heavily on it for battlefield communications. But the drawback to this dependency on a privately owned company such as Starlink was highlighted when Musk denied coverage to Kyiv in 2023.

The investment in Eutelsat not only strengthens space-based collaboration between the UK and France, but also boosts a company providing a backup system for satellite communications.

The US and UK also recently conducted their first coordinated satellite manoeuvre. The US repositioned one of its own satellites to examine a UK satellite to make sure it was operating normally. Such a manoeuvre could potentially be used following an attack designed to disable a spacecraft.

The reports of Russian meddling highlight the importance of security in orbit as global tensions continue to expand into space.

Who are the women supporting Trump?

Source: The Conversation – UK – By Clodagh Harrington, Lecturer in American Politics, University College Cork

Twenty five per cent of US voters think that the Republican party has a better plan for women’s rights than the Democrats, according to new polling.

While many liberal female voters are critical about Donald Trump’s remarks about women as well as his policies related to women’s rights, it’s worth noting that between the 2020 and 2024 presidential elections, Trump increased his support among women voters, from 42% to 45%.

Making assumptions about female voters as a single voting block is tempting, but there are multiple layers and contradictions within this hugely diverse group. Polling shows that there are a few broad conclusions about their voting patterns.

For example, in the modern era, women have higher turnout rates at US elections than men and have consistently been more likely to vote Democrat.

So, who are those women voters that Trump appeals to? The short answer is white women, or at least, some of them. With a couple of election exceptions (1964, 1996) white women tend to prefer Republican candidates over Democrats. They maintained this trend with Donald Trump.

Trumpism and the Maga movement doesn’t tend to appeal to many college-educated white women. However, religion is a factor.

Born-again or Evangelical believers who tend to be committed to the idea of the traditional family where the man goes to work and the woman stays at home and looks after the children have proved essential to Trump’s support in 2024. Eight in ten (80%) of voters who identified as Christian cast their ballots for the Trump/Vance ticket, up from 71% in 2020.

Women in this group may be more likely to appreciate the Trump administration’s attempts to encourage and support women to have more children. Trump’s proposed “National Medal of Motherhood” would create financial incentives for women to have large families. Women with six or more children may be eligible.

The government has already launched what are known as money accounts for growth and advancement. These saving plans will put a US$1000 (£742) deposit from the government into an account for babies born between 2024 and 2028, with families able to add up to US$5,000 annually before the children can access the money at age 18.

Around 64% of all American women support a legal right to abortion. However, national access to abortion is only supported by 39% of Republican women over 50, according to one poll, and this is another group that may be supportive on the Trump administration agenda on families, which has included moves to restrict abortion.

The tradwives movement has become far more widely discussed since it gained support from Maga politicians.

Factory jobs and the future

The Maga-influenced GOP is not the conservative party of yesteryear, but some aspects of its appeal are not new. Voter priority has long been “the economy, stupid”. And around 24% of women (compared to 17% of men) rank inflation and prices as their most important policy issue.

Trump made slashing the price of eggs a major talking point in his recent election campaign, and this will have resonated with women voters worried about the cost of living. Indeed, Trump claimed he won the election on immigration and groceries.

Trump also plans to “fix” the economy and “tariff the hell” out of countries that have “taken advantage” of the US. These policies aim to rebuild US domestic manufacturing. For women in manufacturing communities who have seen the negative impact of globalisation – factory closures, job losses and an undermining of the social fabric – this holds appeal.

Those reliant on the local economy for their livelihoods are aware that the survival of this community ecosystem is crucial, not only for those working in industry but for those whose lives are intertwined. Such views are not necessarily Maga-centric, but the movement’s cultural concerns align with these challenges.

Trump’s promises to reject globalism and “embrace patriotism” may offer comfort to those whose socio-economic security has been undermined by the trade decisions of his predecessors.

Trump’s political opponents would be well advised to listen to the concerns of conventionally conservative America. Dismissing their anxieties will not dissipate them. Instead, it may encourage more socially traditional women to embrace the some of Trump’s policies.

But Trump will also need to worry about the state of the economy, and delivering on his price promises. If he doesn’t deliver, those women who put the cost of living at the top of the list may take their votes elsewhere.

Black hats, cauldrons and broomsticks: the historic origins of witch iconography

Source: The Conversation – UK – By Mari Ellis Dunning, PhD Candidate, Languages and Literature, Aberystwyth University

Whether they’re knocking at your door trick or treating, or hung as decorations in shop windows, witches are rife at this time of year. They’re easy to recognise, wearing tall, pointed hats, carrying broomsticks, or peering into a cauldron – but where did these stereotypes associated with witches come from?

1. Broomsticks

Much like brooms today, in the 1500s the broomstick was a household tool used to sweep hearths and floors. In rural villages, broomsticks were also often used as a form of signage by alewives, who would place them outside their cottages to show that ale was for sale within. Somehow, this innocuous object found its way into stories of witchcraft.

The first image of women flying on broomsticks is believed to be in the manuscript of French poet Martin Le Franc’s Le Champion des Dames (The Defender of Ladies), published in 1485. Women sat astride broomsticks are drawn alongside the text, in the margins of the pages, much as accused witches were often maligned women on the margins of society.

One of the most influential pieces of writing on witchcraft was the Malleus Maleficarum published in 1486 by German clergyman Heinrich Kramer. Kramer’s anti-witchcraft tract alluded to witches flying on anointed broomsticks with the aid of the devil. Given that the work is firmly rooted in misogyny, and depicts witches as a direct threat to the domestic sphere, it’s fitting that such a mundane household item became an object of malice.

2. Cauldrons

Another domestic item, the cauldron, has also become synonymous with witchcraft.

The National Portrait Gallery

Instead of stews and broths, witches are often shown using cauldrons to stir up potions and spells. Again, it’s likely that this is rooted in ideas of women subverting their usual household duties, as well as a connection to healing practices.

In the 16th and 17th century, people relied on lay healers, people who learned their craft through experience and knowledge passed down through the generations. These healers were usually women who had knowledge of herbal remedies and salves that would claim to cure ailments and heal people and sick animals.

As the reformation drew in and the church became more powerful, lay healing practices and unlicensed healing was pushed aside in favour of trained physicians. With this shift, lay healers boiling herbs in their cauldrons were looked on with increasing suspicion.

3. Tall black hats

Concept Art Gallery

Depictions of witches vary across Europe, but there’s no doubt that a tall, black hat has become associated with witches, especially in the UK and the US.

There’s no definitive source for this strange stereotype, but speculation about where it came from is rife, ranging from ideas about Quaker hats to general medieval dress.

Women in early modern (1500 to 1780) Wales typically dressed in long, heavy woollen skirts, aprons, blouses and a large woollen shawl, and a traditional tall, black hat, so there is speculation among some researchers that this served as inspiration for the wide-brimmed hat of the fairy tale witch.

This is fitting given that Wales, along with Cornwall, was seen by Protestant reformers of the early modern period as a land rife with magic and sorcery.

Outside of Europe, tall black hats have also been found on mummies from 200BC unearthed in Subeshi, China, leading scientists to name them the “the witches of Subeshi”.

4. Long, scraggly hair

Depictions of witches usually involve women with long, scraggly hair, often trailing behind them as they ride their broomsticks.

Finnish National Gallery

It’s likely that this conception of witches comes from the dichotomy between “good” Christian women and their “bad” witch counterparts that was established during the reformation.

In the post-medieval period, married women ordinarily covered their hair beneath a cap, and loose hair was generally regarded as an improper attribute of temptresses and the dissolute.

Agnes Griffiths, a Welsh woman accused of witchcraft in 1618, was reportedly seen through the window of her home using something sharp to prick a wax figure, and was described as doing this “with her heare aboute her eares”. The accusation suggests disdain for women who refused to conform to expectations of their gender. In an extension of this, witches were also suspected of hiding wax, which they would use for their sorcery, in their hair, contributing to the stereotype of witches as having greasy locks.

5. Black cats

Women accused of witchcraft between the 14th and 17th centuries were often accused of keeping a familiar – an animal that was actually the devil or a demon in disguise.

De Morgan Centre

Familiar spirits were said to come in any number of guises, from frogs and rats to dogs, small horses and even badgers. In a perverse parody of breastfeeding an infant, witches were believed to feed the familiars from their own bodies, and were often consequently stripped and searched for a “witch’s teat”.

The cleric Robert Holland’s witchcraft treatise, which presents some colourful ideas about witchcraft, recounts a story about a witch who would always have a docile rat feeding in her lap.

It goes on to claim that demons would appear in the form that was easiest to keep as a pet, such as cats, mice and frogs, and tells of an old woman and her daughter who were known to have kept the devil for a long time in various animal guises. Supposedly, the older woman fed the animals with blood from her own breasts.

In one particularly famous case of witchcraft, that of Elizabeth Clarke of Manningtree, Clarke admitted to keeping several familiar spirits, and the most well remembered of these was her cat, Vinegar Tom.

A Protestant candidate has added a twist to Ireland’s presidential race

Source: The Conversation – UK – By Peter John McLoughlin, Lecturer in Politics, Queen’s University Belfast

Ireland will elect a new president on October 24. But not all Irish people will get to vote. Residents of Northern Ireland are not eligible. A Northern Irish candidate can stand in the election – indeed, the Belfast-born Mary McAleese served as president from 1997-2011 – but not vote for themselves, unless they live in the Republic.

This time, one of the two remaining candidates in the race is an Ulster Protestant. Heather Humphreys is a Presbyterian from county Monaghan – one of three Ulster counties that were not included in the formation of Northern Ireland. She is, therefore, a “northerner” – albeit not from Northern Ireland.

Humphreys has sought to use this dualism – being “of Ulster”, but also “of the Irish republic” – to suggest that she understands both political traditions on the island, Ulster unionist and Irish nationalist. But this pitch, and more specifically Humphreys’s religious heritage, have also been turned against her.

Humphreys is standing for Fine Gael, a centre-right Irish party which is part of the current coalition government in Dublin. Jim Gavin, representing Fianna Fáil, the other centrist party in the coalition, was forced to withdraw from the race over a controversy involving his personal financial dealings. This has left Humphreys facing just Catherine Connolly, an independent candidate but former Labour party member who is backed by most of the left-leaning parties in Ireland.

Humphreys describes herself as a republican, but also acknowledges her unionist heritage. Her grandfather signed the Ulster Covenant in 1912. This pledge – signed by thousands of other Ulster Protestants, some in their own blood – committed them to use “all means which may be found necessary” to resist Irish independence.

A Humphreys victory would not entirely be a first, however. Indeed, the very first president of Ireland, Douglas Hyde, was Protestant. He was also the perfect candidate to inaugurate the office, which is largely ceremonial, but symbolically powerful.

A poet and eminent scholar, Hyde was apolitical, and yet had played a crucial role in the “de-Anglicisation” of Ireland – the effort to revive Irish culture, and particularly the native language, corroded by centuries of British rule.

Having a Protestant as its first president also provided a riposte to those who claimed that independent Ireland was a confessional state. The Catholic church was immensely powerful, but Hyde’s presidency suggested an intention to uphold the non-sectarian ideology of republicanism first articulated by Wolfe Tone – one of the many Protestant leaders celebrated in the story of Irish nationalism.

Humphreys has also played a part in this story. In 2016, she was the government minister in charge of the centenary celebrations of the Easter rising – a rebellion against British rule that sparked a renewed struggle for independence, culminating in the establishment of the Irish state in 1921.

The centenary celebrations had the potential to reopen old wounds. But as an Ulster Protestant, Humphreys could claim to understand unionists’ sensitivities, and her handling of the celebrations was broadly deemed a success.

The place of religion in modern Ireland

The last major symbol of Catholic power in Ireland was toppled when voters chose to end the constitutional ban on abortion in 2018. A referendum allowing gay marriage had passed three years earlier, and liberals celebrated what they could now claim was truly the secular republic imagined by Tone. So why has Humphreys’s religion become a point of controversy?

In truth, the question has been raised indirectly, but no less powerfully, by journalists revealing that her husband was previously a member of the Orange Order. This institution is more associated with Northern Ireland and sectarian conflict there.

There are members among the small number of Protestants in the Irish republic, but the Orange Order is quite different in character there, primarily providing a means of association amongst a minority community, and with none of the triumphalist, provocative marching witnessed in Northern Ireland.

Nonetheless, some people in the republic will associate the Orange Order with sectarianism. They may also feel it is fair game to raise this link to a presidential candidate who has suggested that her heritage would allow her to build bridges with unionists.

Such an attribute might be particularly valuable at a time when, post-Brexit, debate on the possibility of a united Ireland has become far more common. This obviously excites Irish nationalists, but has produced paralysing anxiety for many unionists.

And some will see a more malicious intent in raising Humphreys’s link to the Orange Order – a coded questioning of her loyalty to the nationalist tradition in Ireland. There is danger in this. The Northern Ireland Troubles regularly spilled over the border, with Humphreys’s own county particularly affected.

The violence of the Troubles has thankfully ended. But sectarianism has not – and nor is it limited to Northern Ireland.

Whatever the constitutional future of the island, and whatever the outcome of the Irish presidential election, all who hold political power, and all who contribute to public debate, need to be mindful of their words – and the complexity of their history. And southern commentators particularly should remember that there is a reason that the Irish flag includes orange as well as green.

‘Space tornadoes’ could cause geomagnetic storms – but these phenomena, spun off ejections from the Sun, aren’t easy to study

Weather forecasting is a powerful tool. During hurricane season, for instance, meteorologists create computer simulations to forecast how these destructive storms form and where they might travel, which helps prevent damage to coastal communities. When you’re trying to forecast space weather, rather than storms on Earth, creating these simulations gets a little more complex. To simulate space weather, you would need to fit the Sun, the planets and the vast empty space between them in a virtual environment, also known as a simulation box, where all the calculations would take place.

Space weather is very different from the storms you see on Earth. These events come from the Sun, which ejects eruptions of charged particles and magnetic fields from its surface. The most powerful of these events are called interplanetary coronal mass ejections, or CMEs, which travel at speeds approaching 1,800 miles per second (2,897 kilometers per second).

To put that in perspective, a single CME could move a mass of material equivalent to all the Great Lakes from New York City to Los Angeles in just under two seconds – almost faster than it takes to say “space weather.”

When these CMEs hit Earth, they can cause geomagnetic storms, which manifest in the sky as beautiful auroras. These storms can also damage key technological infrastructure, such as by interfering with the flow of electricity in the power grid and causing transformers to overheat and fail.

To better understand how these storms can wreak so much havoc, our research team created simulations to show how storms interact with Earth’s natural magnetic shield and trigger the dangerous geomagnetic activity that can shut down electric grids.

In a study published in October 2025 in the Astrophysical Journal, we modeled one of the sources of these geomagnetic storms: small, tornado-like vortices spun off of an ejection from the Sun. These vortices are called flux ropes, and satellites had previously observed small flux ropes – but our work helped uncover how they are generated.

The challenge

Our team started this research in summer 2023, when one of us, a space weather expert, spotted inconsistencies in space weather observations. This work had found geomagnetic storms occurring during periods when no solar eruptions were predicted to hit Earth.

Bewildered, the space weather expert wanted to know if there could be space weather events that were smaller than coronal mass ejections and did not originate directly from solar eruptions. He predicted that such events might form in the space between the Sun and Earth, instead of in the Sun’s atmosphere.

One example of such smaller space weather events is a magnetic flux rope – bundles of magnetic fields wrapped around each other like a rope. Its detection in computer simulations of solar eruptions would hint to where these space weather events may be forming. Unlike satellite observations, in simulations you can turn back the clock or track an event upstream to see where they originate.

Sometimes the Sun ejects masses of plasma and magnetic field lines, called coronal mass ejections.

So he asked the other author, a leading simulation expert. It turned out that finding smaller space weather events was not as simple as simulating a big solar eruption and letting the computer model run long enough for the eruption to reach Earth. Current computer simulations are not meant to resolve these smaller events. Instead, they are designed to focus on the large solar eruptions because these have the most effects on infrastructure on Earth.

This shortfall was quite disappointing. It was like trying to forecast a hurricane with a simulation that only shows you global weather patterns. Because you can’t see a hurricane at that scale, you would completely miss it.

These larger-scale simulations are known as global simulations. They study how solar eruptions form on the Sun’s surface and travel through space. These simulations treat streams of charged particles and magnetic fields floating through space as fluids to reduce the computational cost, compared with modeling every charged particle independently. It’s like measuring the overall temperature of water in a bottle, instead of tracking every single water molecule individually.

Because these simulations are computational phenomena that happen across such a vast space, they can’t resolve every detail. To affordably resolve the vast space between the Sun and the planets, researchers divide the space into large cubes – analogous to two-dimensional pixels in a camera. In the simulation, these cubes each represent an area 1 million miles (1.6 million kilometers) wide, tall and across. That distance is equivalent to about 1% of the distance from Earth to the Sun.

The search begins

Our search began with what felt like hunting for a needle in a haystack. We were looking into old global simulations, searching for a tiny, transient blob – which would signify a flux rope – within an area of space hundreds of times wider than the Sun itself. Our initial search did not yield anything.

We then shifted our focus to the simulations of the May 2024 solar eruption event. This time, we specifically looked at the region where the solar eruption collided into a quiet flow of charged particles and magnetic fields, called the solar wind, ahead of it.

There it was: a distinct system of magnetic flux ropes.

However, our excitement was short-lived. We could not tell where these flux ropes came from. The modeled flux ropes were also too small to survive, eventually fizzling out because they became too small to resolve with our simulation grid.

But that was the type of clue we needed – the presence of flux ropes at the location where the solar eruption collided with the solar wind.

To settle the issue, we decided to bridge this gap and create a computer model with a finer grid size than those previous global simulations used. Since increasing the resolution across the entire simulation space would have been prohibitively expensive, we decided to only increase the simulation resolution along the trajectory of the flux ropes.

The new simulations could now resolve features that spanned distances six times Earth’s 8,000-mile (or 128,000-kilometer) diameter down to tens of thousands of miles – nearly 100 times better than previous simulations.

A comparison of low and enhanced simulation grid sizes. We identified one flux rope in the original, low-resolution simulation, but it soon fizzled out. When we improved the simulation grid, we could see multiple flux ropes.

Making the discovery

Once we designed and tested the simulation grid, it was time to simulate that same solar eruption that led to the formation of those flux ropes in the less fine-grained model. We wanted to study the formation of those flux ropes and how they grew, changed shape and possibly terminated in the narrow wedge encompassing the space between the Sun and Earth. The results were astonishing.

The high-resolution view revealed that the flux ropes formed when the solar eruption slammed into the slower solar wind ahead of it. The new structures possessed incredible complexity and strength that persisted far longer than we expected. In meteorological terms, it was like watching a hurricane spawn a cluster of tornadoes.

We found that the magnetic fields in these vortices were strong enough to trigger a significant geomagnetic storm and cause some real trouble here on Earth. But most importantly, the simulations confirmed that there are indeed space weather events that form locally in the space between the Sun and Earth. Our next step is to simulate how such tornado-like features in the solar wind may impact our planet and infrastructure.

This two-dimensional cut of the simulation box shows a solar eruption that moves toward Earth quickly. The eruption slams into the slower solar wind ahead of it, causing the formation of a constellation of magnetic flux ropes. The magnetic flux ropes appear as islands in the simulation box. The solid lines represent magnetic field lines, and the color bar shows the number of charged particles. Flux ropes move toward Earth upon formation in the solar wind. The video also shows how the Space Weather Investigation Frontier space mission, or SWIFT, a constellation of four satellites forming a tetrahedron configuration, could examine the formation and growth of these structures in the solar wind.

Watching these flux ropes in the simulation form so quickly and move toward Earth was exciting, but concerning. It was exciting because this discovery could help us better plan for future extreme space weather events. It was at the same time concerning because these flux ropes would only appear as a small blip in today’s space weather monitors.

We would need multiple satellites to directly see these flux ropes in greater detail so that scientists can more reliably predict whether, when and in what orientation they may affect our planet and what the outcome may be. The good news is that scientists and engineers are developing the next-generation space missions that could address this.

Trade is shaping new global power relations: what this means for Africa

Source: The Conversation – Africa – By Arno J. van Niekerk, Senior lecturer in Economics, University of the Free State

Over the past two decades, economic strength, trade flows, technological leadership and even consumer demand have been moving steadily from west to east. This transformation is redrawing economic maps. It is also raising urgent questions about co-operation, competition and inclusion in a multipolar world. Lecturer in economics and finance Arno van Niekerk answers questions about these issues, which he explores in a new book, West to East: A New Global Economy in the Making?

What indicates a shift from west to east?

Brics countries, largely driven by China and India, overtook the G7 countries in their share of global GDP in 2018. As Figure 1 shows, the Brics contribution has grown from 32.33% of global GDP to 35.43% in 2024 (after being at 21.37% in 2000).

Figure 1

The G7’s share decreased to 29.64%, from 43.28% in 2000.

This marks a historic turning point. Economic leadership that was long concentrated in the west has decisively shifted towards emerging economies.

Another strong indicator of the shift is the change in global shares of trade of the G7 and Brics countries. This is particularly true of exports. Data shows that Brics+ (11 countries, including new members) captured 28% of world exports in 2024, closing in on the G7’s 32%.

The rebalancing of global trade dynamics has wide-ranging consequences for international business. It means, especially in the case of China and India, that these economies are doing more than expanding in scale. They are also integrating effectively into global value chains, improving productivity and raising living standards.

As shown in Figure 2, the share of global merchandise exports of the G7 countries fell from 45.1% in 2000 to 28.9% in 2023. For their part, the Brics+ share rose from 10.7% (2000) to 23.3% (2023).

Figure 2

There are other indicators too:

  • Over two-thirds of global foreign exchange reserves are held in Asia. In particular, in China (US$3 trillion), Japan, India and South Korea. Large reserves indicate that a nation earns more from exports, investment inflows and remittances than it spends on imports and debt payments.

  • China has displaced western dominance in foreign direct investment in developing regions. Through its Belt and Road Initiative – involving over 150 countries – it has become the world’s largest source of outbound foreign direct investment.

  • Asia now accounts for more than half of the global middle class, driving demand growth. Asia is projected to represent over 50% of global consumer spending. This compares with less than 20% in 1990.

  • China, India, South Korea and Japan have become leaders in financial technology, artificial intelligence and 5G adoption. China now files more international patents annually than the US and European Union combined. Specifically, the tech rivalry between the US and China illustrates the change in technological leadership.

What does this shift tell us about economic co-operation?

Countries in both the east and the west need to make more intentional efforts. This is necessary, firstly, to address the growing geoeconomic tension. And secondly to move the world towards a shared vision for sustainable economic progress that benefits all countries.

Such co-operation needs to go beyond traditional trade and investment agreements. It should be deliberately structured to reduce inequalities, strengthen resilience and embed sustainability.

I identify five main areas for co-operative initiatives.

Co-ordinated policy frameworks: tax co-operation in the form of global minimum corporate taxes to ensure fair revenue for social investment. Harmonise labour and social protections through common standards to prevent exploitation. Align sustainable development by embedding the Sustainable Development Goals, the Paris Agreement targets and human rights principles into trade and financial agreements.

Inclusive trade and investment: fair trade agreements to ensure that market access benefits small producers, women and marginalised communities. Establish regional value chains that support developing countries in upgrading within global value chains – so that they don’t just supply raw materials. Design co-operative frameworks for technology transfer, especially for sharing green and digital technologies at affordable costs.

Financial co-operation: innovative financing mechanisms, such as green and social bonds, blended finance and climate funds need to be made accessible to low-income countries. Implement co-operative mechanisms for debt relief and restructuring. This will help address unsustainable debt that crowds out social spending. Forge public-private partnerships for inclusion to co-finance social infrastructure. This includes education, health and digital access.

Knowledge and capacity building: joint research platforms are required to enable more collaborative work on climate adaptation, food security and inclusive digitalisation. South-south and triangular co-operation should be increased to share experiences and best practices among developing nations with support from multilateral institutions. Managed labour mobility schemes through skills partnerships will benefit both sending and receiving countries.

Governance and multilateral reform: reforming global institutions like the World Bank, International Monetary Fund and World Trade Organization is essential to give developing economies stronger voices in these institutions.

What should African countries be doing?

China, India and other leading eastern countries have proven themselves formidable rivals to the west – economically, militarily and in global governance. Africa occupies a central position. It has the opportunity to become a key player in shaping the future of the global economy.

A number of recommendations should serve as priority areas – particularly over the next decade.

The first would include building a digital backbone, and enhancing technology and AI capabilities. These have become core drivers of competitiveness. Without infrastructure and skills, countries are relegated to raw-material suppliers.

Countries need:

  • a national broadband and data-centre strategy (public-private), and incentives to attract the building of regional data centres

  • more training in science, technology, engineering, maths and artificial intelligence. Examples include fast-track bootcamps, ICT in secondary schools and support for local AI startups.

Secondly, governments should continue to secure investment in digital infrastructure, such as fibre optics, 5G networks and data centres. They could potentially use China’s Digital Silk Road, which promotes affordable tech alternatives.

Secondly, South Africa and other African countries need to prioritise economic inclusion and sustainable development to fast-track broad-based inclusive economic development. This should be the core driver of their development strategy.

Thirdly, African governments must strategically navigate geopolitical shifts and alliances. They are key spheres of influence in the digital competition between the US and China, and ought to use this position to their benefit. To do this, Africna governments should:

  • use Brics+ membership in a co-ordinated way to advance national interests

  • foster south-south co-operation by strengthening trade, technological transfer and financial alliances with other developing countries in Asia, Africa and Latin America. More emphasis should be placed on initiatives like the Forum on China-Africa Co-operation.

  • enhance trade diplomacy and diversify markets to be able to sell more goods and services in Asian, European and intra-African markets

  • maximise external investment by securing investments, infrastructure and digital partnerships from both the US and China. This will position African countries to benefit from the global technology competition.

West Africa’s trade monitoring system has collapsed – why this is dangerous for food security

Source: The Conversation – Africa – By Olivier Walther, Associate Professor in Geography, University of Florida

A decade ago countries in West Africa set up a unique trade monitoring mechanism. Its purpose was to track intra-regional trade in agricultural products and livestock in the region. But the system was closed down in 2022 due to a lack of funding by regional organisations.

The mechanism provided West African countries with data from more than 320 markets and along 10 corridors, enabling the tracking of not only trade patterns but livestock and zoonotic diseases.

The lack of up-to-date trade data has a number of knock-on effects. Detailed intra-trade data are essential to help assess the impact of external shocks that can significantly affect food security and economic development. These include political crises, extreme weather events, currency devaluation, or epidemics.

Good data is also essential for mapping trade networks. In turn, this can strengthen market information systems and disease surveillance efforts. These rely heavily on the movement of goods, people, livestock and capital across the region.

Using data collected by the Permanent Interstate Committee for Drought Control in the Sahel from 2013 to 2017, researchers show the importance of considering the social structure of trade networks, their geography and temporal changes.

The social structure of trade networks could better inform market information systems and disease surveillance, both of which rely heavily on the movement of goods, people, livestock and capital across the region

They conclude that regional bodies should support the resumption of trade data collection. They should also foster dialogue with national statistical offices and other national institutions that have experience in collecting data on informal regional food trade to work towards a coherent regional statistical approach.

A unique database on the regional economy

In West Africa, agricultural goods and livestock trade operates in well-established corridors. Animals, for example, flow from the Sahel to the major urban centres of the Atlantic Coast and of the Gulf of Guinea.

Our analysis of the trade data suggests that border markets play a key role in livestock trade and that a large proportion of movements are trans-boundary.

This high level of mobility facilitates the spread of livestock and zoonotic diseases. These include Rift Valley fever, Crimean-Congo haemorrhagic fever, Foot and Mouth disease, and Peste des petits ruminants. At the end of September 2025, for example, a new outbreak of Rift Valley fever was observed in Mauritania and Senegal. The two West African countries have very close ties when it comes to animal movements.

The transnational nature of trade in West Africa led to the creation of a regional database by the Permanent Interstate Committee for Drought Control in the Sahel in 2013. Data collected on more than 320 markets and along 10 corridors, from Guinea and Senegal in the west to Nigeria in the east, were unique on the African continent.

The data was particularly well suited for analysis of locally-produced food stuff and livestock at the regional level. This is because it incorporated both formal and informal trade. Both are prevalent throughout the region. Our recent work estimates informal activities could reach up to 85% of total trade, representing US$10 billion. This is six times higher than portrayed in official statistics

Filling the statistical gap

The experience of recent years and the transnational nature of trade flows suggest one key step. That being regional institutions, rather than bilateral donors, take over data collection.

Initially, the data were collected within the framework of the Permanent Interstate Committee for Drought Control in the Sahel’s Regional Support Program of Market Access. This was developed to increase the volume and value of trade within the Economic Community of West African States and the West African Economic and Monetary Union .

From 2017 to 2019, the United States Agency for International Development provided funding to establish the database as part of its West Africa/Regional Agriculture Office. The data was eventually integrated to the ECOWAS Informal Cross Border Trade database. This was developed to monitor informal cross-border trade in the region in 2019.

The United States Agency for International Development programme ended in 2019. After this, data collection was transferred to the Family Farming, Regional Markets and Cross-Border Trade Corridors in the Sahel project. Launched in 2020, its aim was to develop a sustainable and self-financed means of collecting reliable data on agricultural and food trade in West Africa.

Funding for these activities was provided by the International Fund for Agricultural Development. It was locally managed by the West African Association for Cross-Border Trade in Agro-forestry-pastoral and Fisheries Products, based in Togo.

This initiative, covering 17 countries unfortunately came to an end in 2022 (agricultural products) and 2024 (livestock).

The cessation of this funding has had dire effects. It profoundly affected researchers’ ability to measure the impact of structural and political changes affecting the region. For example, it is still impossible to measure the extent to which the closure of certain borders following successive coups in Mali, Burkina Faso, and Niger in recent years has affected the trade networks linking the Sahel to the Gulf of Guinea.

Better data to monitor trade and animal diseases

Re-establishing a permanent data collection system by supporting local associations such as the West African Association for Cross-Border Trade in Agro-forestry-pastoral and Fisheries Products is one of the essential steps for policymakers wishing to strengthen the region’s resilience.

The World Animal Health Organisation’s International Animal Health Code has suggested centralising livestock mobility data. This could be a starting point. It is the most efficient way to prevent and respond to transnational disease spread through trade.

Accurate, timely and centralised data collection could help identify possible hotspots and reconstruct transmission patterns. It could also develop control measures and alert systems to protect unaffected areas.

Beyond disease control, resuming the collection of data on intra-regional trade would also contribute to design policies that support the adaptation of regional economy to new climate conditions and political unrest. Better trade data on West Africa’s informal sector could unlock climate adaptation finance by highlighting its real value.

For instance, in one of our latest reports, we estimate that regional livestock exports for Mali, Niger and Burkina Faso are likely to be close to USD 1 billion when counting unrecorded trade, against USD 80 million in official statistics.

The research for this article was carried out in conjunction with Mr. Brahima Cissé who coordinates the Regional Markets program at the Economic Community of West African States in Togo; Dr. Alban Masaparisi, an economist specialising in food systems transformation and agricultural policy at the OECD Sahel and West Africa Club, France and Mr. Koffi Zougbede, an economist working on food systems at the OECD Sahel and West Africa Club, France.__

Why are elements like radium dangerous? A chemist explains radioactivity and its health effects

“What is radium and why is it dangerous?” – Aurora, 10, Laredo, Texas


The element radium can be found in extremely tiny amounts in the Earth’s crust and oceans, and in its pure form it is a soft silvery metal. To an untrained eye, a small piece of radium may look like a chip off a regular gray rock. But radium can invisibly emit radiation – energy and small fragments of itself – that you can’t feel, see or smell. And that invisible radiation can hurt you, without you even noticing right away.

What’s going on with this silent threat that can stealthily damage your body in ways that can take years to reveal themselves?

As a chemist, I’m interested in what makes different elements safe to handle or hazardous. This dangerous release of radiation is called radioactivity, and even though its source may look unassuming, it can burn you or even give you diseases that don’t manifest for years.

Atoms and isotopes

Everything you see around you – your skin, rocks, the pages of books – is all made up of different combinations of extremely small particles called atoms.

An atom has a small, dense center called the nucleus. Negatively charged particles called electrons move around the nucleus. Inside the nucleus, there are two types of particles: positively charged protons and neutral neutrons.

All atoms with the same number of protons in their nuclei are the same element. Besides radium, some elements you may have heard of are carbon and oxygen. All carbon atoms have six protons and all oxygen atoms have eight protons. Radium atoms are much heavier – all radium atoms have 88 protons.

Interestingly, it is possible for atoms of the same element to have different numbers of neutrons. Atoms of the same element with different numbers of neutrons are called isotopes. For instance, two carbon atoms would each have six protons, but one might have six neutrons while another could have seven or eight.

The number of protons and neutrons packed together in the nucleus determines whether the nucleus of an isotope is stable or not. If the nucleus is not stable, problems can arise.

Radioactive decay

The nucleus of each atom wants to be stable, but only certain arrangements of protons and neutrons make that possible. The number of protons and neutrons do not have to be equal, but some combinations make for a happy, or stable, coexistence in the nucleus while others don’t.

A nucleus with an unhappy mix of protons and neutrons might break down or deteriorate in some way. That process is called radioactivity or radioactive decay.

Elements are radioactive if they decay by releasing parts of the nucleus or high-energy particles.

That radioactive decay process releases some form of radiation from the nucleus. This radiation can take the form of tiny particles moving rapidly or high-energy electromagnetic waves emerging from the nucleus. It is that radiation – the high-energy particles and waves shooting out from the nucleus of unstable atomic nuclei – that can make you sick.

There are different types of radioactive decay. In one case, an atom decays by kicking out a small fragment of itself that is made up of two protons and two neutrons. Since the number of protons determines what element we have, decay that changes the number of protons in an atom turns it into a different element.

Radioactive decay can be quite slow, though. It can take thousands of years for one element to decay into a different one.

The case of radium

All radium atoms are unstable and radioactive. Many of these isotopes decay very quickly, but Ra-226, which has 138 neutrons and 88 protons and is the most common, decays the slowest. It takes 1,600 years for half a sample of Ra-226 to decay.

Radium undergoes alpha decay, where it loses a fragment of its nucleus containing two protons and two neutrons, after which it becomes radon.

As Ra-226 decays, it loses two protons and two neutrons, which turns it into an isotope of radon. Then the radon decays, and the atom eventually reaches a stable form as the element lead. Each step in that decay series releases more nuclear radiation.

Some other elements in nature with no stable isotope are technetium, polonium, actinium and uranium.

Effects on the human body

The nuclear radiation emitted when radium and other elements decay can damage the cells in the human body. It can lead to cancers or other health problems.

Marie and Pierre Curie experimented with radium, which ended up causing health complications for them.
André Castaigne

Whether you’re exposed to a lot of radiation quickly, like making the mistake of walking around for a few hours with radioactive material in your pocket, or you’re exposed to just a little over a long time, the high-energy particles and electromagnetic waves from nuclear radiation can lead to serious health problems, including burns and cancers.

Remarkably, even though radioactivity is a threat to life, scientists can control and use it to diagnose and treat diseases – including cancers. If the radiation is delivered precisely to where cancer cells are, the radiation can destroy those rogue cells wreaking havoc in the body.

People who work professionally with radioactive materials need to follow strict guidelines and procedures to protect themselves. They use special shields and radiation detectors, and they minimize the amount of time they’re exposed to any radioactivity.

Pierre and Marie Curie, who discovered radium in 1898, suffered some of the negative effects of radioactivity. Pierre experienced radioactive burns, and Marie died from a blood disease likely caused by chronic radiation exposure. Over 100 years later, her notebooks are still radioactive.
