Cannabis: it’s medicine if you’re rich enough – a crime if you’re not

In Britain, whether cannabis is treated as medicine or a crime may depend less on medical need than on the ability to pay. In 2018, the UK government changed drug policy, allowing specialist doctors to prescribe cannabis-based medicinal products.

The decision was presented as a move towards evidence-based healthcare, recognising cannabis may have therapeutic value for health conditions such as chemotherapy-induced nausea and vomiting, spasticity in adults with multiple sclerosis and treatment-resistant epilepsy. Nearly seven years later, though, access remains highly restricted. According to NHS guidance, medical cannabis is tightly controlled and usually considered only when other treatments have failed.

In practice, NHS prescriptions remain rare, with most patients accessing cannabis privately at considerable cost. For many others, legal access is simply unavailable.

Cannabis is recognised as medicine, yet people using it therapeutically without a prescription can still face criminal sanctions. The problem is not simply legal inconsistency but structural inequality.

While medical cannabis is legal in principle, the route to obtaining a prescription is narrow. Clinical guidance remains cautious, many doctors are reluctant to prescribe it, and patients find it difficult to navigate the system.

Those unable to afford private treatment are often left with limited options: go without treatment, rely on less effective alternatives, or obtain cannabis illegally.

The result is effectively a two-tier system in which legality is shaped not just by medical need, but by economic means. Those who can pay privately may use cannabis lawfully. Those who cannot may risk criminalisation for materially similar behaviour.

The financial barriers are significant: private patients must pay for consultations, clinic registration fees, ongoing review appointments and the medication itself. Prescriptions can run to hundreds of pounds a month, with some products priced at around £8.99 per gram.

By comparison, street cannabis typically costs £150-£200 per ounce, making it significantly cheaper – making the illicit market not just more accessible for some, but economically rational.

People who can’t access legal cannabis may be pushed towards unregulated supply chains linked to organised criminal networks. Unlike prescribed products, cannabis bought illegally has no quality checks, no guaranteed strength and no doctor overseeing how you use it. There is no guarantee it is free from harmful synthetic additives.

This creates another policy contradiction. A system intended to regulate cannabis use may, through its own restrictions, be sustaining the illicit markets it was meant to displace.

The inequality can exist even within the same household. Two people may use the same cannabis product for similar health reasons, yet only one is legally protected because they can afford the consultation fees and prescription charges required to access private treatment. The other, unable to absorb those costs, risks criminal sanctions for similar behaviour.

Legal dilemma

People using cannabis to manage chronic pain, anxiety, trauma or other long-term conditions may already be navigating significant health difficulties. Relying on illegal supply introduces additional stress, uncertainty and the fear of criminalisation on top of an already difficult health situation.

For some, the experience of breaking the law while attempting to manage their wellbeing may itself contribute to feelings of stigma, anxiety and social exclusion. This matters because research consistently shows that drug use is often functional – a way of managing pain, stress or trauma – rather than purely recreational.

In this context, self-medication with cannabis may represent a response to unmet medical need rather than deviance. Yet the law rarely accounts for this complexity. Unauthorised possession remains a criminal offence regardless of intent.

Cannabis occupies an increasingly ambiguous position in British society. According to the Office for National Statistics, it remains the most commonly used illicit drug in England and Wales. At the same time, alcohol retains a firmly established cultural and legal status despite its association with addiction, violence and long-term health harms.

One substance remains criminalised despite growing medical recognition and comparatively lower levels of harm. The other is culturally embedded despite well-documented links to addiction, violence and early death.

NHS England recorded over 1 million alcohol-related hospital admissions in 2023-24, alongside more than 22,000 alcohol-related deaths. Cannabis, by comparison, is not associated with mortality at that scale.

None of this means cannabis is without risk. Heavy use can produce dependency and mental health complications for some users, although others report relief from chronic pain, anxiety and related conditions. But the current policy framework appears difficult to justify on the basis of relative harm alone.

The continued policing of low-level cannabis possession also carries a cost to the criminal justice system, consuming police and court capacity at a time of serious backlogs.

A coherent cannabis policy would need to align law, medical evidence and lived reality. At present, UK policy sends contradictory messages. Cannabis is simultaneously framed as both a medicine and a criminal substance, depending less on how it is used than on how it is accessed.

When the difference between a prescription and a criminal record is money, that tells you everything about who a drug law is really for.

Eric Morecambe at 100: the beloved British comedian with an anarchic northern spirit

Source: The Conversation – UK – By Glyn White, Senior Lecturer in 20th-Century Literature and Culture, University of Salford

For many people over the age of 50, the first few bars of an old 1960s song will always prompt a smile. Bring Me Sunshine, adopted by comedians Morecambe and Wise as their theme tune in 1969, came to define the pair who sang it at the end of every show.

May 14 2026 marks the centenary of the birth of Eric Morecambe, “the funny one” to Ernie Wise’s straight man, together regarded as Britain’s pre-eminent comedy double act of the 1960s and 1970s. Recognition of that milestone is boosted by the rediscovery of a lost episode from the first BBC series of The Morecambe and Wise Show, from September 16 1968 – the corporation plans to broadcast it on his century birthday.

Morecambe was then 42 and at the beginning of a BBC run lasting until 1977 that would produce a series of Christmas specials on which the duo’s fame largely rests. Half a century later, these specials are still a feature of the BBC’s Christmas line-up. But it is difficult to convey how much of an institution Morecambe and Wise were in that three-channel 1970s world of television.

In 1999 Queen Elizabeth dedicated the statue of Morecambe on the promenade of his home town, whose name the young Eric Bartholemew adopted. There are more than ten books about the comedian, and the late Victoria Wood wrote and performed in Eric and Ernie (2011) about their early years. The hunt for missing shows that led to the recent discovery has found episodes as far afield as Sierra Leone.

An enduring double act

But why does the affection for Morecambe and Wise endure? As an academic with a specialism in TV comedy, I’m keen to explore Morecambe’s contribution to the continuing fascination with this double act.

The pair were brought together through talent shows and music-hall impresario Jack Hylton in the early 1940s. Initially Wise had the bigger name and the edge in song and dance. The double act had to be paused when they were old enough to be conscripted – Wise into the merchant navy, Morecambe as a miner in Accrington where he experienced a heart murmur, a shadow of what was ahead.

Post-war BBC Radio success led to an unhappy television debut, Running Wild (1954), but the duo were too good to be off screen for long. They became regulars on other series, until hired as the stars of ATV’s Two of a Kind (1961-68). The appearance of the Beatles on the show in 1963, right on the cusp of international stardom, illustrates these two sparky live performers’ fast, funny, irreverent signature style.

When John Lennon tries to make a point about his dad telling him about Morecambe and Wise when he was younger, indicating his height at the time, Eric responds “You’ve only got a little dad, have you?” and everyone dissolves into laughter, including Ernie.

It’s clear that while there was a script, delivered more or less successfully, there is also improvisation catching fellow performers on the hop. When Ernie sets up a joint rendition of Moonlight Bay, Eric storms in wearing a Beatles wig singing lines from their hits. He’s an aggressive, anarchic, decidedly northern spirit.

There was always a slapstick element to their comedy that takes real professionalism to make work, and to roll with it when things goes wrong. For this they drew on their music-hall roots and learned from film performers, too.

Writer Eddie Braben’s Morecambe and Wise Show sketches have them co-habiting like Laurel and Hardy and, like Oliver Hardy, Eric breaks the fourth wall, speaking to the audience directly, usually to highlight his awareness of how badly things are going. Their humour is quintessentially British.

Despite a real desire to break America, and numerous appearances on the hugely popular Ed Sullivan Show, they were not to be part of the “British invasion” of the 1960s. Instead they were regarded with real affection in a drab mid-century Britain seeking a bit of sunshine.

The great and the good flocked to appear on their Christmas specials in musical numbers and plays “wot Ern wrote”. It worked best when the guest brought some gravitas that could be undermined, as with stern classical actress Glenda Jackson, who revealed a real talent for comedy, and newsreader Angela Rippon, who revealed she had legs and an unsuspected ability to dance that is remembered today.

With male celebrities there is often an edge of rivalry. The best-known sketch of the Christmas Specials, from 1971, sees globally renowned conductor André Previn drawn in under false pretences by Ernie who has promised him the chance to work with violinist Yehudi Menuhin, setting up confusions over names. In the end Previn becomes Andrew Preview as Eric destroys Grieg’s Piano Concerto with “all the right notes just not necessarily in the right order”.

Previn managed to hold his own (and keep an admirably straight face) despite being unable to attend scheduled rehearsals, and it is noticeable how much Morecambe claps the other performers at the end. He feeds on live interaction that teeters breathlessly on the brink of collapse. This sketch is lightning in a bottle with Morecambe’s role as conductor of chaos.

But it took its toll. That early heart murmur would turn into near-fatal heart attacks in 1968 and 1979, and a fatal one in 1984, backstage after half a dozen curtain calls at a solo event. Morecambe was just 58, undoubtedly with more to give on many fronts, from comedy to writing and acting.

Watching the famous Breakfast Sketch (1976) used to irritate me, because to my younger self those pancakes weren’t going to be any good with all that eggshell in them, and the oranges weren’t cut into even halves.

But for me now, at 59, Eric and Ernie’s playfulness is clearly about the joy of being alive in the moment. The legacy of Eric Morecambe in entertainment terms is about delivering sunshine: having the ability to make such moments, and to produce them to order. There can never be enough of them.

From AirTags to AI nudification: the growing toolkit of technology-facilitated abuse

Source: The Conversation – UK – By Jason R.C. Nurse, Reader in Cyber Security, University of Kent

It’s hard to overstate the impact that artificial intelligence has had since the release of generative AI platforms such as ChatGPT just three years ago. While they have led to countless advances in how we live and work, they have also been at the centre of controversies around domestic and sexual abuse.

The use of the AI tool Grok to remove women’s clothing in images brought the issue of so-called technology-facilitated abuse to the fore. But it’s a problem that predates AI – with Bluetooth trackers, wearable devices, smart speakers, smart glasses and apps all used by abusers to control, harass or stalk their victims.

This abuse has worsened as tech has become more embedded in people’s lives, and as AI advances rapidly. But governments have struggled to make tech companies design systems that minimise misuse, and to hold them accountable when things go wrong.

Our own research has confirmed that technology misuse has increased and that its harms are significant. But governments and the tech sector are doing little to combat it – despite numerous examples of how tech can enable abuse.

Case 1: Smart glasses

The growing availability of smart glasses – which look like normal eyewear but can do many things a smartphone does – has led to reports of secret filming. In some cases, videos were posted online, often attracting degrading and sexually explicit comments.

Meta has said its smart glasses have a light to show when they are recording and anti-tamper tech to make sure the light cannot be covered. But there appear to be workarounds.

In England and Wales, voyeurism legislation focuses on private spaces, and harassment laws do not specifically apply to targeted recording and online distribution. However, the UK Information Commissioner’s Office is investigating Meta after subcontractors were allegedly able to access intimate footage from customers’ glasses. This is in addition to a lawsuit in the US, which alleges Meta violated privacy laws and engaged in false advertising. Meta has said that it takes the protection of data very seriously and that faces are usually blurred out. It also discloses in its UK terms of service the potential for content to be reviewed either by a human or by automation.

Case 2: Bluetooth trackers

Apple’s AirTags, and other devices built for tracking personal items, can be misused to stalk and harass people, particularly women. Apple released updates to AirTags and other trackable tech so that potential victims would be alerted if an unknown device was travelling with them. But for many, this feature should have existed from the outset.

The law in England and Wales is clear that attaching tracker devices to someone without their knowledge is a criminal offence. But despite convictions, the ease of covertly monitoring people using these devices means people continue to be at risk.

Case 3: AI deepfake and ‘nudification’ apps

Apps can now “nudify” people, while AI is increasingly used to make non-consensual deepfake pornography. In January, several instances of xAI’s assistant Grok being used to create sexualised photos of women and minors came to light. All it took to create the images were some simple prompts.

After criticism, xAI decided to limit this feature. But the safeguards appear to apply only to certain jurisdictions and certain users.

In February, the UK government announced legal changes similar to the Take It Down Act in the US, which will require tech platforms in the UK to remove non-consensual intimate images within 48 hours. Failure to do so will result in fines and services being blocked, and the law is likely to be implemented from summer.

Using automated technology known as “hash matching”, victims will only need to report an image once to have it removed from multiple platforms simultaneously. The same images would then be automatically deleted every time anyone attempted to reupload them. Nudification apps and using AI chatbots to create deepfake pornography will also become illegal in the UK.

But there is more to be done. Mitigating risks must be embedded at the design stage to prevent these images being created in the first place. The rise of romantic and sexual chatbots means this has become more urgent.

And beyond deepfakes and nudification, AI can also enable harassment at scale. This includes directly targeting someone with abusive content, or fake images or profiles that impersonate victims for so-called “sextortion” scams.

Challenges ahead

These issues must be prevented with robust guardrails built into these technologies. This is what prioritising user safety should look like, after all. But often, these guardrails have failed. Safety tools are only usually added after public pressure, not built into platforms from the start.

Governments have allowed regulation to fall behind fast-paced developments. Tech companies have grown quickly, but laws and enforcement have not kept up. At the same time, police and legal systems are often under-trained or unclear on how to handle digital harm.

Even where there is regulation, such as the UK’s Online Safety Act, penalties for platforms that allow abuse are often weak or unenforceable. The regulator Ofcom has issued only voluntary guidance to tech companies on how to better protect women and girls on their platforms. Campaigners have called for this to be made mandatory, with clear penalties for companies that do not comply, placing it on a level legal footing with child sexual abuse and terrorism content.

As AI advances, tech companies must prioritise system design that puts user safety first. But until governments enforce real consequences, the tech sector will be able to profit from harm while those using the platforms bear the cost.

Europe is rearming itself without addressing the political consequences

Source: The Conversation – UK – By Richard Youngs, Professor of International and European Politics, University of Warwick

Compounding the alarm triggered by Russia’s 2022 full-scale invasion of Ukraine, the erratic unpredictability of the second Trump administration has made the need for European security autonomy obvious. On a number of occasions over the past year, Donald Trump has loosely intimated that he might leave the Nato defence alliance.

Washington’s recent move to withdraw 5,000 troops from Germany, plus unease over the US’s actions in Iran, have reinforced the imperative of European strategic independence. The US administration announced its planned withdrawal after the German chancellor, Friedrich Merz, criticised Trump’s Middle Eastern adventurism.

European rearmament is well underway. Governments still need to follow through on their promises to increase defence budgets to Nato’s new 5% of GDP target. But in 2025, European Nato members and Canada spent US$574 billion (£422 billion) on defence – an increase of nearly 20% on the previous year. This was the sharpest annual rise for 70 years.

The security debate should now move into a new phase in which European governments grasp the complex political implications of rearmament. These are gradually becoming apparent. Examples include a sharper trade-off between spending on defence and social programmes, and the prospect of Germany gaining military superiority as well as economic dominance.

There is also the danger of rightwing populist parties taking power with hugely increased military arsenals. Such parties are currently leading polls in France, Germany, the UK and several other countries, on agendas that sit uneasily with longstanding European security cooperation.

European militarisation adds to the eye-watering military build-up globally, which is increasing the risk of major conflict. There is also the harmful environmental impact of rearmament, and the threat of over-militarisation crowding out Europe’s focus on non-military security – an approach rooted in social development and conflict prevention.

These challenges show that rearmament represents a foundational shift for the European order. Simply grafting this defence build-up on to unreformed EU and Nato structures is likely to create new imbalances.

The EU risks losing its value as a peace project if it morphs into a security union without a more balanced and comprehensive political settlement.

Addressing the consequences

Concerns are rising in several European countries about the need to embed and constrain future German military power within a more deeply integrated EU. Calls for a “European army” are resurfacing, most recently by the Spanish government – but still without political precision.

Defence spending is growing not just through national governments, but EU-level instruments that entail deeper collective security. Many European governments are pushing towards Nordic-style, whole-of-society security in which military and civilian resources mobilise in unison. The EU’s Preparedness Union Strategy, introduced in 2025, is aimed at this too.

Such considerations show that a securitised Europe must be underpinned by continent-wide political debate and channels of accountablity. As citizens are asked to mobilise around full-spectrum defence, they need a greater say in security policies. They need a voice in the trade-offs that higher defence spending will require, and how to manage issues such as Germany’s incipient military predominance.

However, the process of rearmament is currently being carried out in a way that reinforces the opaque, crisis-mode features of EU decision-making that have nourished illiberal populist parties. Europe will struggle to legitimise its security turn without rivitalising its collective political system in ways that provide stronger and more active societal input.

European powers are currently seeking to act more assertively in defence of their immediate geopolitical interests. They are doing so while not entirely jettisoning the liberal-order principles of rules-based cooperation and openness.

But they are struggling to inject this combination with clear, precise content. European governments have not, together, defined a common position on how far European rearmament should be used to project sharper-edged power externally, in addition to dissuading aggression against European territory.

European security deployments and conflict prevention elsewhere in the world have retrenched in recent years. The withdrawal of EU military forces from Africa’s Sahel region is perhaps the most notable example. It is unclear whether the current security turn aims to reverse this trend, or move further in the same direction.

Rearmament also raises questions about the organisational structure of the European order. Security dynamics are altering power balances and the relationship between different regional bodies. They are dragging the UK back into European affairs, for example, and prompting talk of new, flexible forms of alliance across the continent.

Upgrading European burden-sharing and coordination within Nato is overdue. But the alliance is unlikely to suffice as a structural, ordering principle for post-Trump security autonomy. Other formats will be needed to allow greater thematic and geographic adaptability.

Discussions took place on defence and security matters at the European Political Community summit in Armenia on May 4. It involved not only EU member states but the UK and other non-EU European powers. Recent European coalition efforts covering Ukrainian security and navigation in the Strait of Hormuz may herald a trend towards functional and shifting clusters of states.

Security debates do not neatly match the EU’s economic and regulatory space – and this invites reflection on innovative formats. Excluded from EU security plans, the British government especially needs to be ready with proactive ideas that contribute to structural reordering, well beyond negotiations of the current EU-UK reset.

As the EU finalises its new security strategy and the UK moves forward with implementing its strategic defence review, European governments need to address the political ramifications of rearmament. These present harder, more structural challenges than hiking defence budgets – but currently, governments are pushing them down the road.

Until these challenges are resolved, European rearmament will rest on shaky foundations, and generate many difficulties in its wake.

The hidden role of export credit in the energy transition

Source: The Conversation – France – By Igor Shishlov, Affiliate Professor – Climate Change Economics, HEC Paris Business School

For most policymakers, export credit agencies (ECAs) are financial tools that boost national companies’ business endeavours abroad. But a recent research project conducted by Philipp Censkowsky, Paul Waidelich, Igor Shishlov, and Bjarne Steffen reveals the profound impact they have on the energy transition. Our study analysed 921 energy-finance deals backed by ECAs from 31 countries between 2013 and 2023.

We used commercial transaction data to track how much ECAs invested in fossil fuels versus renewable energy. We also examined key policy shifts to understand how international agreements influence the decisions ECAs make.

Are ECAs slowing down or speeding up the low carbon transition? For years, export credit agencies have been key players in global trade finance, providing state-backed loans, insurance and guarantees to support national exporters. But their role in the energy transition is now under scrutiny.

While some ECAs have made strides in shifting finance away from fossil fuels, many remain deeply entangled in financing oil, gas and even coal — the dirtiest fuel of them all.

Our research underscores this reality. ECAs are major enablers of energy
infrastructure worldwide, and their continued support for fossil fuels is at odds with international climate commitments.

What’s holding ECAs back from making a full transition?

These agencies have historically played a crucial role in financing fossil fuel projects by de-risking investments for private lenders. This influence is massive — comparable to multilateral development banks — yet their role in shaping the energy transition has been largely underexplored in academic research.

In our study, we found a clear trend:

ECAs are slowly pivoting towards renewable energy, but fossil fuel projects still receive a large share of support, even as international pledges like the Glasgow Statement call for the phasing out of international fossil fuel financing.

A fragmented shift

Our paper shows that, in 2013, only 9% of ECA energy commitments went to
renewable energy technologies (RETs). By 2023, that share had jumped to over 40%.

While this suggests a significant shift, the total dollar amount of fossil fuel financing remains high.

Certain ECAs, particularly those in Europe, have made stronger commitments to “greening” their portfolios, while others — like those in Japan, South Korea and China — continue to support fossil fuel infrastructure.

Breaking down financing patterns reveals important nuances:

  • Coal financing has has sharply declined among OECD ECAs, following the
    adoption of international restrictions. However, some non-OECD countries
    continue to finance coal projects, particularly in emerging economies.

  • Oil and gas projects still dominate ECA commitments, especially in the
    early stages of production and transportation. Even as financing for coal
    declines, oil and gas deals receive billions in state-backed support.

  • Wind energy leads the charge in renewables financing, with large offshore projects securing significant ECA backing. Solar and hydrogen projects, while growing, still lag behind.

One of the most striking findings of our research is that ECA-backed renewable energy investments are overwhelmingly concentrated in high-income countries.

Developing nations — where clean energy investment is most needed — receive
little support, a trend driven by the high perceived financial risks, and a lack of strong policy incentives.

Policies’ limitations

Why do some ECAs lead in the energy transition while others lag behind?

A key factor is their mandate and political will of their respective governments. Many ECAs are designed primarily to promote national exports and domestic job creation, with little regard for climate or sustainability objectives. This narrow focus has made it difficult for ECAs to pivot away from fossil fuels, even when their governments have pledged to do so.

Some countries, however, are starting to rethink this approach. In the UK and the Netherlands, studies have shown that shifting export finance from fossil fuels to renewables can actually create more domestic jobs. ECAs in countries that have integrated climate goals into their mandates — like those in the Export Finance For Future (E3F) coalition — tend to be leading the way in shifting finance towards renewables.

But without clear and binding international rules, many ECAs cite their mandates as an excuse to continue financing fossil fuels. For example, the Export–Import Bank of the United States (EXIM) has justified continued oil and gas support under its “non-discrimination” clause, even though the US government under the Biden Administration has pledged to end international public finance for fossil fuels.

Global cooridnation

A fragmented policy landscape creates loopholes. When one country’s ECA pulls out of fossil fuel financing, others may step in to fill the gap.

This “free-rider” dynamic may weaken the impact of national-level climate commitments, and underscores the need for stronger international cooperation.

The most important global policy framework for ECAs is the OECD Arrangement
on Officially Supported Export Credits
, which already includes restrictions on coal financing. But negotiations to expand these rules to oil and gas have stalled, despite pressure from climate advocates and progressive governments.

Former US President Joe Biden’s administration attempted to push for stricter rules in late 2023 but failed to secure agreement from key countries like South Korea and Turkey, which is set to host COP31 – the next UN Climate Change Conference.

In our paper, we argue that reviving global dialogue on ECA climate policy beyond the OECD is crucial. Without a coordinated approach, fossil fuel-dependent economies will continue to resist change, and financing for clean energy will remain unevenly distributed.

Policy recommendations going forward

So, what can policymakers do to accelerate the transition? Here are three key recommendations:

  1. Redefine ECA mandates: National governments should integrate climate
    and sustainability objectives into their ECA policies, ensuring that export
    finance aligns with broader climate commitments.

  2. Expand international agreements: Strengthening the OECD Arrangement
    on Officially Supported Export Credits to include oil and gas restrictions
    would create a level playing field and prevent countries from undermining
    each other’s progress.

  3. Improve financing mechanisms for developing countries: High capital costs and political risks make it difficult for emerging economies to attract clean energy investment. ECAs could help by offering financial support and lower-cost loans for renewable energy projects in developing countries.

Ultimately, ECAs are a powerful but underutilised tool in the fight against climate change.

If policymakers take bold action to reform export finance, these institutions could become catalysts for a just and rapid energy transition. But without stronger mandates and international cooperation, they risk being a barrier rather than a solution.

Applications

The impact of ECAs depends on whether governments align their mandates with
climate goals.

Redirecting finance from fossil fuels to renewables, expanding support in developing economies, and strengthening international agreements, could make ECAs a driving force in decarbonisation.

‘Poverty porn’: the moral dilemma behind MrBeast’s billion-dollar empire

Source: The Conversation – Global Perspectives – By Paul Formosa, Professor and Head of the Department of Philosophy, and Co-Director of the Macquire University Ethics & Agency Research Centre, Macquarie University

YouTube/MrBeast

Jimmy Donaldson, better known as MrBeast, runs the most subscribed-to YouTube channel in the world (with 484 million subscribers) and has an estimated net worth of US$2.6 billion.

He is also a prominent philanthropist. Beyond his involvement in fundraising initiatives such as #TeamTrees, which claims to have planted more than 24 million trees worldwide, Donaldson runs a dedicated Beast Philanthropy YouTube channel.

He claims 100% of profits from this channel’s ad revenue, merch sales and sponsorships go towards helping others. This has included paying for 1,000 cataract surgeries, constructing a medical clinic for children rescued from slavery, and building 100 wells to provide clean water in Africa.

These impressive philanthropic endeavours have dramatically improved the lives of their recipients. How could any of this be controversial?

The murky ethics of ‘stunt philanthropy’

Many of Donaldson’s videos involve subjecting people to what might be seen as degrading or exploitative situations, in exchange for money.

In Donaldson’s “Ages 1 – 100 Decide Who Wins $250,000” video, contestants (including young children) are put in an intense competitive structure and forced to eliminate one another. We see a grown man help to intentionally eliminate an 11-year-old girl, which leads to her sobbing on camera.

In another video, he tells a random group of shoppers they will win US$250,000 if they are the last to leave the store. Under pressure to stay, they are kept from their families and forced to endure poor living conditions, with some experiencing emotional breakdowns.

These videos have been labelled by various critics as “poverty porn”, as they could be seen as exploiting the desperation of vulnerable people to generate clicks and ad revenue.

The Beast Games reality series, which airs on Prime Video, is also built around challenges designed to provoke contestants into backstabbing one another, experiencing emotional distress, and revealing depressing stories about how badly they need the money.

Allegations against Donaldson also extend to behind the scenes, particularly in regards to the culture of work in his companies.

In 2024, several contestants who took part in Beast Games filed a lawsuit against Donaldson’s MrB2024 and other companies involved in the production. They allege they were subject to “chronic mistreatment”, including the infliction of emotional distress, inadequate food and rest breaks, delays in receiving medication, exposure to dangerous conditions, and a failure to prevent sexual harassment.

More recently, a former Beast Industries employee sued two of Donaldson’s production companies after suffering alleged sexual harassment and gender bias at work.

You can’t morally offset exploitation of people

When it comes to assessing the ethics of Donaldson’s work, one option is to take a simple “consequentialist” perspective. Act consequentialism is the view that the right action is the one which leads to the most amount of good.

If a few people suffer exploitative conditions so many more people can enjoy life-saving surgery, then the moral calculus is likely to come out in favour of this situation. Of course, there are longstanding philosophical worries with such a view.

The 18th century philosopher Immanuel Kant argued it is wrong to use others as tools to achieve our own ends, even if our ends are morally admirable. Treating some people as mere means right now can’t be morally justified by promising to help others later on.

According to Kant, one’s motives for helping others are also important, and the moral worth of an action is determined by these motives. So helping others out of a sense of duty has a moral worth that doing the same act out of self-interest does not.

Is Donaldson’s philanthropy motivated by duty and care for others, or by clicks, esteem and ad-revenue? Or perhaps both?

We can’t know the answer. Although, Kant himself did believe all humans are likely to be morally corrupt at the very root of their character.

Consent and power

Irrespective of Donaldson’s motives, a broader point remains: his philanthropic videos are an integral part of his overall brand. The philanthropy helps to make the other, more exploitative videos (and the significant revenues they generate) more “morally palatable”.

After all, Donaldson could simply give his money away. He doesn’t need to make people compete, scheme and suffer for it.

One might counter that the participants have consented to being involved. But when you offer people in economically vulnerable situations potentially life-changing amounts of money to endure degrading conditions, the “voluntariness” becomes contestable.

This is not what ethicists consider “informed consent”. The offer can be so large that it clouds judgement. And for people without genuine alternatives, saying “no” may not be a realistic option.

The fact that Donaldson sometimes subjects himself to similar treatment, such as when he buried himself alive for seven days, deepens rather than lessens the worry, given the power asymmetries at play. He owns the production company, controls the conditions, and profits from the content in ways other participants do not.

The underlying structural concerns

When political problems, such as poverty, or a lack of access to healthcare or clean water, are reduced to entertainment, they undergo a form of what scholars call “depoliticisation”. Political failures that demand collective action, institutional reform and democratic deliberation instead become fodder for entertainment.

If we think we can help solve these problems just by watching viral videos, then we can avoid facing the structural issues that underpin them.

370 billion crickets are farmed for food every year. Scientists have discovered they may feel pain

You’re cooking dinner, distracted, and your hand brushes a hot pan. Nerve signals race to your spinal cord and back to yank your arm away in a fraction of a second, with no thought required.

Then comes the pain. A sharp, spreading sting gives way to a pulsing ache, and you cradle your hand and run it under cold water until it subsides. That felt experience is distinct from the reflex that preceded it. While the reflex moved your body out of danger, pain drives you to protect the wound, recover, and learn to avoid similar mistakes in the future.

We readily accept that other people feel pain by reading cues in their behaviour, like the inspection and nursing of an injury. We extend this to some animals too – a dog licking its paw or a cat favouring a limb rightly stir our sympathies. But what happens when we turn that lens on animals far less like us?

In our new study, published in Proceedings of the Royal Society B, we searched for behavioural signs of pain in house crickets, one of the most widely farmed insects. After applying heat to an antenna, we found that crickets didn’t just reflexively flinch and recover. They nursed the harm, returning again and again to groom the affected site, much as we rub a burned hand.

The frontiers of feeling

French philosopher René Descartes considered animals unfeeling biological machines, and for centuries the circle of moral concern barely extended beyond our own species.

But the boundaries have steadily crept outward. Recognition that mammals experience pain came first, followed by birds. Fish too, once assumed to lack the necessary brain structures, are now widely accepted as capable of pain-like states.

The leap into invertebrates has been greater and more contentious. Their nervous systems bear little resemblance to our own, so arguments from brain anatomy alone don’t carry us far. Instead, we look to behaviour. Does the animal respond to harm in ways that go beyond reflex, ways that are flexible, persistent, and sensitive to context?

Over the past decade, testable indicators for pain in non-humans have been developed and are increasingly accepted. These include learning from unpleasant events, trading off harms against rewards, and actively protecting the site of injury. Evidence meeting these criteria helped crabs and lobsters gain legal recognition as sentient under United Kingdom law in 2022.

Among insects, the evidence has been accumulating fast. Yet most of this evidence comes from bees. Bumblebees weigh the risk of harm against the richness of a food reward, and groom the site of an injury. Honeybees learn to associate particular smells with harmful stimuli and avoid them.

Far less attention has been paid to Orthoptera, the group that includes grasshoppers, locusts and crickets. That gap matters, because the house cricket (Acheta domesticus) is the world’s most widely farmed insect, with more than 370 billion reared annually.

Do crickets feel pain?

We tested 40 male and 40 female crickets, each experiencing three conditions in random order: a hot probe to a single antenna (65°C, to activate damage receptors but not cause lasting injury), the same probe unheated, or no contact at all.

We filmed their behaviour for ten minutes. Observers scoring the footage did not know which treatment any animal had received.

The results were clear. After the hot probe, crickets were more than twice as likely to groom the affected antenna compared to controls, and spent roughly four times longer doing so.

Could this simply reflect general disturbance rather than targeted care? Unlikely: grooming was directed specifically at the heated side, not spread evenly across both antennae as it was after gentle touch or no contact.

And the behaviour wasn’t a brief, reflexive reaction. It was elevated from the outset and tapered gradually over minutes, much like rubbing a burned hand as the felt sting slowly fades.

Small minds, big feelings

Subjective experience cannot be directly observed in any animal, not even humans.

But we have shown crickets respond to harm in a way that satisfies a key criterion many scientists and philosophers use to infer pain: flexible, directed self-protection. Combined with the knowledge that crickets possess damage receptors, can learn to avoid harms, and respond less to injury under morphine, the weight of evidence for an inner life is growing.

The practical stakes are real. Hundreds of billions of farmed insects are slaughtered each year by freezing, boiling and baking. Pesticides kill trillions more, optimised for lethality with no consideration of potential suffering.

If we take a precautionary approach, credible evidence of suffering should motivate proportionate protections well before we are certain.

Insects have been around for more than 400 million years and are far more behaviourally and cognitively sophisticated than once assumed. The question, then, may not be whether some insects feel, but why we ever assumed they couldn’t.

Your local storm forecast is likely based on weather miles away – mesonets can help bridge that gap

Whether you’re planning a weekend hike, deciding what to wear to work or preparing your home for severe storms, the weather forecast is essential. You might instinctively grab your smartphone and check an app for an instant weather update.

But how many times have you looked at your app, only to step outside and see the sky painting a different picture than what’s on your screen?

As a meteorologist who operates a weather station network in Wisconsin, I’ve heard many of the same cliches time and again: “The weatherman is always wrong!” “Just wait five minutes and the weather will be different!”

Before you blame the local forecasters, let’s talk about where the data in your weather app comes from, and why it might not always show what you expect. It’s why my colleagues and I are working to bring forecast data closer to home.

The nuts and bolts of weather forecasting

Earth is huge. It has a diameter of 7,926 miles (12,756 kilometers) at the equator and has 62 miles (100 kilometers) of atmosphere overhead.

If you want a perfect weather forecast, you will have to precisely measure every molecule of the atmosphere, land and water, and perfectly predict how they will interact with each other for the next minute, day or week. This is, of course, physically impossible.

Instead, scientists run computer models. These models take the observations we do have and simulate the weather on a large scale to a remarkable degree of accuracy. In fact, storm track forecasts from the National Hurricane Center were among its best ever in 2025, and forecasts using machine learning are starting to improve those forecasts even further.

These models are hungry for data. Supercomputers ingest measurements from satellites, weather balloons, Doppler radar, lightning detection networks, buoys, surface weather stations and other measurement platforms to solve the equations that provide weather predictions.

When you open your phone, your weather app isn’t doing the meteorology – it’s just showing the output of the model’s calculations. Even though they generally aren’t tailored by a local meteorologist, these short-term forecasts are usually pretty good. But they could be better.

All weather is local

You’ve probably seen it before: It’s raining on one side of the street and not on the other. You flip on the news to see the nearest airport received an inch of rain, but your garden is dry.

There are more than 2,500 airports in the United States with weather stations, which is where much of the weather data shared on TV and online is collected. But for many people, the closest airport is more than 20 miles (32 kilometers) away. This is especially true in rural areas.

A map shows large gaps in many states, particularly across the West but also in large parts of Mississippi, Alabama, Missouri and Arkansas, as well as regions of the Northeast.
All of the areas in green are more than 20 miles from an airport weather station. In many cases, that means they’re 20 miles or farther from the weather observations feeding their local forecasts.
Chris Vagasky

Because of the chaotic nature of weather, the only way to truly know what’s happening in your yard is to measure the weather in your yard. But not everyone is interested in installing a rain gauge or personal weather station.

Filling the gaps

To bridge this gap, many states and universities have established local weather station networks called mesonets – short for mesoscale networks, meaning intermediate scale. These weather stations are installed in locations to ensure everyone in the state is within 20 miles of the nearest station.

Nationally, there are nearly 3,000 mesonet stations installed in 38 states, with more networks planned.

Like the weather stations at airports, mesonets measure things like air temperature and relative humidity, air pressure, rainfall or melted snow, and wind speed and direction – often every five minutes.

Many mesonets collect additional data such as soil moisture levels to help farmers. Some even have camera images updated every five minutes to show current weather conditions. Mesonet data is then shared through websites or direct data transmission so that the public, weather forecasters and researchers can easily access it.

I lead the team at Wisconet, a new mesonet that just finished installing 78 weather stations across Wisconsin. Our stations are installed on 10-foot-tall (3-meter) tripods in open areas near orchards and cranberry marshes, farms and airfields, schools and other educational centers, and on city, state and federally owned lands.

Wisconet weather stations, like this one in Amery, Wisc., provide local weather data for areas where forecasts used to be based on what was happening many miles away.
Caitlin Wienkes, Wisconet

These added weather stations are already proving useful. On Aug. 18, 2025, slow-moving thunderstorms moved over a Wisconet station, with more than 3 inches of rain falling in just a couple of hours. The National Weather Service was able to issue a flash flood warning for the area because of the data provided by that station.

In addition to providing a near-real-time snapshot of the local weather, mesonets help farmers decide when to run irrigation systems, spray pesticides or plant crops. They also help provide better weather warnings, particularly when tornadoes and other storms intensify over small areas that farther-away weather stations would miss.

A nationwide network of networks

Because of the immense value of high-frequency weather and soil measurements, the National Oceanic and Atmospheric Administration leads a National Mesonet Program. The program collects weather data from public, private and academic sources, validates the quality of the data, and ensures it flows to users, including the National Weather Service. National Weather Service forecasters use that data to make more timely and accurate severe weather warnings.

Congress is considering expanding that program, with legislation proposed in the House and the Senate. The bills aim to authorize $50 million to $70 million annually to the National Mesonet Program between 2026 and 2030 to improve and expand mesonets across the country. An expansion would mean more weather stations and new capabilities, like real-time snowfall, fire weather and air quality measurements, closer to the people who rely on them.

So the next time you check your smartphone and grumble because the app doesn’t match the weather in your backyard, remember that all weather is local. If you don’t have a nearby mesonet station, the nearest measurements may be many miles away.

Bilingualism and sex hormones may provide a new link to brain resilience and dementia risk

Source: The Conversation – Canada – By Noelia Calvo, Research Associate, Neuroscience, University of Toronto

Why do some people maintain good memories and have healthy brains even as they age?

Research that my colleagues and I recently published in Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring, explored the effects and interactions of social, linguistic and endocrinological factors on cognitive health.

With Canada’s aging population, the question of brain health is a relevant one. The most recent census in 2021 indicated that one in eight Canadians is aged 70 or over, and there are 1.7 million who are age 80 or older. These numbers show a growing population of older adults at increased risk of cognitive decline, highlighting the need to examine protective factors.

Previous research indicates that bilingualism may be a possible protective factor. Notably, the 2021 census indicated that bilingualism is also increasing among Canadians, with four in 10 (41 per cent) speaking more than one language.

While bilingualism may be one piece of the puzzle, other cognitive or biological factors also influence brain health. Verbal memory — the ability to remember words — has been linked to cognitive resilience. The presence of sex hormones such as estrogen and testosterone, which are present in both men and women, may also influence how the brain ages.

Studying a trio of factors

The relationship between these three factors — bilingualism, verbal memory and sex hormones — has not been studied before. To address this gap, my colleagues and I conducted a new study in Canada. We found that bilingualism may interact with verbal memory and sex hormones to influence dementia risk in unexpected ways.

Our study included data from 335 older adults with mild cognitive impairment and 170 patients with Alzheimer’s disease drawn from the Comprehensive Assessment of Neurodegeneration and Dementia (COMPASS-ND) cohort, which is part of the Canadian Consortium on Neurodegeneration and Aging.

COMPASS-ND includes more than 1,200 Canadian adults aged 50–90 years recruited across more than 30 sites nationwide. Using this rich and current database, we examined how sex hormones, verbal memory and bilingualism jointly influence cognitive resilience, brain structure and blood-based markers of Alzheimer’s disease.


This article is part of our ongoing series The Grey Revolution. The Conversation Canada and La Conversation are exploring the impact of the aging boomer generation on Canadian society, including housing, working, culture, nutrition, travelling and health care. The series explores the upheavals already underway and those looming ahead.


We created a resilience index for each participant that incorporated sex hormones, verbal memory, bilingual proficiency, education, age and immigration status. Age, education, and immigration status were included as covariates because they may influence cognitive resilience through differences in language experiences, educational opportunities and sociocultural adaptation across the lifespan.

Each unit increase in the resilience index was associated with a significant reduction in the odds of dementia-related pathology. Higher resilience index scores were also linked to better performance on clinical diagnostic tools such as the Montreal Cognitive Assessment (MoCA), as well as lower levels of key markers associated with neurodegeneration and glial activation, a process in which the brain’s support cells become reactive in response to injury or disease.

Overall, bilingual participants showed the highest resilience index scores, but with notable differences in how these effects manifested across biological sex.

Our findings challenge the idea that risk and resilience can be understood by looking at biological or social factors in isolation. By studying bilingualism and sex hormones together, we reveal how these factors may interact to shape brain resilience.

Bilingualism and verbal memory

Another important finding of our study was related to verbal memory. Consistent with previous research, women showed better performance in verbal memory. This sex difference is clinically important because verbal memory is often used as a proxy for general cognitive function, meaning it can influence how dementia is diagnosed in women.

One might expect that bilingual women would be especially protected, since they have both the bilingualism benefit and strong verbal memory.

Surprisingly, our study found the opposite: bilingual men showed greater brain protection. Our findings suggested that a combination of two factors may be a mechanism behind enhanced verbal memory and cognitive resilience in aging men: aromatization — the conversion of testosterone into estradiol — and bilingual language experience.

In people with mild cognitive impairment, higher estradiol levels produced through aromatization, together with bilingualism, may work synergistically to protect verbal memory, making older bilingual men more resilient to cognitive decline and neurodegenerative pathology.

Overall, our study suggests that bilingual men may have greater resilience to neuropathology and that sex hormones could influence dementia risk in aging women. These findings underscore the need for more research on how sex hormones affect brain health, as well as the importance of using measures beyond verbal memory to improve the accuracy of cognitive decline diagnoses in Canada.

AI doesn’t create bias, it inherits it – how do we ensure fairness when it comes to automated decisions?

Source: The Conversation – UK – By Michael Mayowa Farayola, PhD Graduate, School of Computing, Dublin City University

Hiring algorithms are one of the systems that could be affected by discrimination. PeopleImages

If artificial intelligence (AI) systems shape decisions that affect people’s lives, they should do so fairly. This should be a given considering that potential applications for AI include automated hiring systems, as well as tools used in education, finance and criminal justice.

But ensuring the fairness of AI systems is far more complex than it might sound. Despite years of research, there is still no consensus on what fairness means, how it should be measured, or whether it can ever be fully achieved.

Fairness inherently depends on context. What counts as fair in one domain may be inappropriate or even harmful in another. In criminal justice, fairness may prioritise avoiding disproportionate harm to particular communities. In education, it may focus on equal opportunity and long-term outcomes.

In finance, it often involves balancing access to credit with risk assessment. Because AI systems must be formalised mathematically, researchers translate fairness into technical definitions expressed through metrics that specify how outcomes should be distributed across groups.

These metrics are useful tools, but they are not neutral. Each encodes assumptions about which differences matter and which trade-offs are acceptable.

Problems with the data

A deeper issue lies in the data itself. AI systems learn from historical datasets that reflect past decisions, institutional practices, and social inequalities. When a model is trained to replicate observed outcomes, such as hiring decisions or loan and mortgage approvals, it may reproduce existing injustices under the appearance of objectivity.

Optimising for one notion of fairness often means violating another. This tension is evident in automated loan approval systems. An algorithm may be designed so that applicants with the same predicted probability of default are treated similarly across demographic groups.

Yet one group may still be more likely to be incorrectly denied credit, while another may be more likely to receive loans they later struggle to repay. Fairness in predictive accuracy can therefore conflict with fairness in how financial risk and opportunity are distributed.

These differences often reflect structural inequalities embedded in the data the model is trained on. Groups that have historically faced barriers to credit, due to factors such as discrimination or exclusion from financial systems, may have thinner credit histories or lower recorded incomes.

As a result, models can treat socioeconomic disadvantage as a signal of higher risk, even when it does not reflect an individual’s actual ability to repay.

The same pattern emerges in hiring. If a company historically promoted fewer women into senior roles, a system trained to predict “successful” candidates may learn patterns that favour characteristics more common among men, even if gender is not explicitly included as an input. In both cases, the model does not invent bias, it inherits it.

A fundamental question is whether AI systems mirror the world as it was, or attempt to correct for known injustices.

The idea of fairness is further complicated by how it is assessed. Many assessments examine a single protected attribute, such as gender or race, in isolation. While common, this approach can obscure how discrimination operates in practice.

An automated hiring system might appear fair when comparing men and women overall, and fair when comparing ethnic groups overall, yet it might also consistently disadvantage older women from minority backgrounds.

Structural inequalities may be embedded in the data used for AI systems covering everything from mortgage approvals to loans.

Complex evaluation

People are defined by several characteristics that intersect, including age, ethnicity, disability, and socioeconomic background. Because these intersectional subgroups are often small and underrepresented in data, the harms they face may remain invisible in standard evaluations.

This invisibility has a direct technical consequence. When a subgroup is small, the model encounters too few examples to learn reliable patterns for that group and instead applies generalisations drawn from the broader categories it has seen more of, which may not reflect that group’s actual characteristics or circumstances.

Errors and biases affecting small subgroups are also less likely to surface in standard performance metrics, which aggregate results across all users and can therefore mask poor outcomes for minorities within minorities. Which means that those most at risk are therefore often the least visible.

These challenges suggest that fairness in AI cannot be reduced to better metrics or more sophisticated algorithms. Fairness is shaped by institutional context, historical legacies, and power relations.

Decisions about what data to collect, which objectives to optimise, and how systems are deployed are influenced by social and organisational factors. Technical fixes are necessary but insufficient. Meaningful approaches must engage with the broader context in which AI systems operate.

This includes involving interested parties beyond engineers and data scientists. People affected by AI systems, often members of marginalised communities, possess contextual knowledge about risks and harms that may not be visible from a purely technical perspective.

Participatory approaches, in which affected groups contribute to the design and governance of AI systems, acknowledge that fairness cannot be defined without considering those who bear the consequences of automated decisions.

Even when interventions appear successful, they may not remain so. Societies change, demographics shift and language evolves. A system that performs acceptably today may produce unfair outcomes tomorrow. In particular, recent advances in large language models, the technology underlying many widely used AI tools, add further complexity.

Unlike traditional systems that make specific predictions, these models generate language based on vast collections of historical text. Such datasets inevitably contain stereotypes and imbalances.

Fairness is therefore not a one-time achievement but an ongoing responsibility requiring monitoring, accountability, and a willingness to revise or withdraw systems when harms emerge.

Together, these challenges suggest that fairness in AI is not a purely technical problem awaiting a finite solution. It is a moving target shaped by social values and historical context.

Rather than asking whether an AI system is fair in the abstract, a more productive question may be: fair according to whom, under what conditions, and with what forms of accountability? How we answer that question will shape not only the systems we build, but the kind of society they help to create.
