Scopolamine, more chillingly known as “devil’s breath,” is a drug with a dual identity. In medicine, it’s used to prevent motion sickness and nausea. But in the criminal underworld, particularly in parts of South America, it has gained a dark reputation as a substance that can erase memory, strip away free will and facilitate serious crimes. Now, its presence may be sparking fresh concerns in the UK.

While most reports of devil’s breath come from countries like Colombia, concerns about its use in Europe are not new. In 2015, three people were arrested in Paris for allegedly using the drug to rob victims, turning them into compliant “zombies”.

The UK’s first known murder linked to scopolamine was reported in 2019 when the Irish dancer Adrian Murphy was poisoned by thieves attempting to sell items stolen from him. In a more recent case in London, a woman reported symptoms consistent with scopolamine exposure after being targeted on public transport.

Scopolamine, also known as hycosine, is a tropane alkaloid, a type of plant-derived compound found in the nightshade family (Solanaceae). It has a long history: indigenous communities in South America traditionally used it for spiritual rituals due to its potent psychoactive effects.

In modern medicine, scopolamine (marketed in the UK as hyoscine hydrobromide) is prescribed to prevent motion sickness, nausea, vomiting and muscle spasms. It also reduces saliva production before surgery. Brand names include Kwells (tablets) and Scopoderm (patches).

As an anticholinergic drug, scopolamine blocks the neurotransmitter acetylcholine, which plays a vital role in memory, learning, and coordination. Blocking it helps reduce nausea by interrupting signals from the balance (vestibular) system to the brain. But it also comes with side effects, especially when used in high doses or outside a clinical setting.

How it affects the brain

Scopolamine disrupts the cholinergic system, which is central to memory formation and retrieval. As a result, it can cause temporary but severe memory loss: a key reason it’s been weaponised in crimes. Some studies also suggest it increases oxidative stress in the brain, compounding its effects on cognition.

The drug’s power to erase memory, sometimes described as “zombifying”, has made it a focus of forensic and criminal interest. Victims often describe confusion, hallucinations and a complete loss of control.

Uses and misuses

In clinical settings, scopolamine is sometimes used off-label for depression, excessive sweating, or even to help quit smoking. But outside these uses, it’s increasingly associated with danger.

Recreational users are drawn to its hallucinogenic effects – but the line between tripping and toxic is razor thin.

In Colombia and other parts of South America, scopolamine, also known as burundanga, has been implicated in countless robberies and sexual assaults. Victims describe feeling dreamlike, compliant, and unable to resist or recall events. That’s what makes it so sinister – it robs people of both agency and memory.

The drug is often administered surreptitiously. In its powdered form, it’s odourless and tasteless, making it easy to slip into drinks or blow into someone’s face, as some victims have reported. Online forums detail how to make teas or infusions from plant parts, seeds, roots, flowers – heightening the risk of DIY misuse.

Once ingested, the drug works quickly and exits the body within about 12 hours, making it hard to detect in routine drug screenings. For some people, even a dose under 10mg can be fatal.

Signs of scopolamine poisoning include rapid heartbeat and palpitations, dry mouth and flushed skin, blurred vision, confusion and disorientation, hallucinations and drowsiness.

If you experience any of these, especially after an unexpected drink or interaction, seek medical attention immediately.

Ghana and India: Narendra Modi’s visit rekindles historical ties

Source: The Conversation – Africa (2) – By Pius Siakwah, Senior Research Fellow, Institute of African Studies, University of Ghana

Narendra Modi’s trip to Ghana in July 2025, part of a five-nation visit, is the first by an Indian prime minister in over 30 years. The two countries’ relationship goes back more than half a century to when India helped the newly independent Ghana set up its intelligence agencies. Ghana is also home to several large Indian-owned manufacturing and trading companies. International relations scholar Pius Siakwah unpacks the context of the visit.

What is the background to Ghana and India’s relationship?

It can be traced to links between Kwame Nkrumah, Ghana’s first president, and his Indian counterpart, Prime Minister Jawaharlal Nehru, in 1957. It is not surprising that the Indian High Commission is located near the seat of the Ghana government, Jubilee House.

Nkrumah and Nehru were co-founders of the Non-Aligned Movement, a group of states not formally aligned with major power blocs during the cold war. Its principles focused on respect for sovereignty, neutrality, non-interference, and peaceful dispute resolution. It was also a strong voice against the neo-colonial ambitions of some of the large powers.

The movement emerged in the wave of decolonisation after the second world war. It held its first conference in 1961 under the leadership of Josip Bros Tito (Yugoslavia), Gamal Abdel Nasser (Egypt) and Sukarno (Indonesia) as well as Nehru and Nkrumah.

The relationship between Ghana and India seemingly went into decline after the overthrow of Nkrumah in 1966, coinciding with the decline of Indian presence in global geopolitics.

In 2002, President John Kufuor re-energised India-Ghana relations. This led to the Indian government’s financial support in the construction of Ghana’s seat of government in 2008.

Though the concept of the Non-Aligned Movement has faded this century, its principles have crystallised into south-south cooperation. This is the exchange of knowledge, skills, resources and technologies among regions in the developing world.

South-south cooperation has fuelled India-Ghana relations. Modi’s diplomatic efforts since 2014 have sought to relaunch India’s presence in Africa.

In recent times, India has engaged Africa through the India–Africa Forum Summit. The first summit was held in 2008 in New Delhi with 14 countries from Africa. The largest one was held in 2015, while the fourth was postponed in 2020 due to COVID-19. The summit has led to 50,000 scholarships, a focus on renewable energy through the International Solar Alliance and an expansion of the Pan-African e-Network to bridge healthcare and educational gaps. Development projects are financed through India’s EXIM Bank.

India is now one of Ghana’s major trading partners, importing primary products like minerals, while exporting manufactured products such as pharmaceuticals, transport and agricultural machinery. The Ghana-India Trade Advisory Chamber was established in 2018 for socio-economic exchange.

Modi’s visit supports the strengthening of economic and defence ties.

The bilateral trade between India and Ghana moved from US$1 billion in 2011-12 to US$4.5 billion in 2018-19. It then dipped to US$2.2 billion in 2020-21 due to COVID. By 2023, bilateral trade amounted to around US$3.3 billion, making India the third-largest export and import partner behind China and Switzerland.

Indian companies have invested in over 700 projects in Ghana. These include B5 Plus, a leading iron and steel manufacturer, and Melcom, Ghana’s largest supermarket chain.

India is also one of the leading sources of foreign direct investment to Ghana. Indian companies had invested over US$2 billion in Ghana by 2021, according to the Ghana Investment Promotion Center.

What are the key areas of interest?

The key areas of collaboration are economic, particularly:

  • energy

  • infrastructure (for example, construction of the Tema to Mpakadan railway line)

  • defence

  • technology

  • pharmaceuticals

  • agriculture (agro-processing, mechanisation and irrigation systems)

  • industrial (light manufacturing).

What’s the bigger picture?

Modi’s visit is part of a broader visit to strengthen bilateral ties and a follow-up to the Brics Summit, July 2025 in Brazil. Thus, whereas South Africa is often seen as the gateway to Africa, Ghana is becoming the opening to west Africa.

Modi’s visit can be viewed in several ways.

First, India as a neo-colonialist. Some commentators see India’s presence as just a continuation of exploitative relations. This manifests in financial and agricultural exploitation and land grabbing.

Second, India as smart influencer. This is where the country adopts a low profile but benefits from soft power, linguistic, cultural and historical advantages, and good relationships at various societal and governmental levels.

Third, India as a perennial underdog. India has less funds, underdeveloped communications, limited diplomatic capacity, little soft power advantage, and an underwhelming media presence compared to China. China is able to project its power in Africa through project financing and loans, visible diplomatic presence with visits and media coverage in Ghana. Some of the coverage of Chinese activities in Ghana is negative – illegal mining (galamsey) is an example. India benefits from limited negative media presence but its contributions in areas of pharmaceuticals and infrastructure don’t get attention.

Modi will want his visit to build on ideas of south-south cooperation, soft power and smart operating. He’ll want to refute notions that India is a perennial underdog or a neo-colonialist in a new scramble for Africa.

In 2025, Ghana has to navigate a complex geopolitical space.

The mistakes Keir Starmer made over disability cuts – and how he can avoid future embarrassment

Source: The Conversation – UK – By Thomas Caygill, Senior Lecturer in Politics, Nottingham Trent University

Labour MPs have forced a major government climbdown over disability benefit cuts, in an embarrassing turn of events for Keir Starmer. The prime minister has blown a hole in his budget by agreeing to scrap plans to tighten eligibility criteria for disability benefits via the universal credit and personal independence payment bill.

In return, MPs passed what was left of the bill – although 49 of them still rebelled, voting against the government. The bruising encounter bodes poorly for the future. Starmer’s Number 10 operation has been shown to be unable to communicate effectively with MPs. The team was neither able to win MPs over when the bill was being developed, nor bring them into line when agreement could not be reached.

The question now must be whether Starmer will ever be able to push through any difficult legislation in the future. He now needs to give serious attention to his relationship with MPs.

The government has insisted that welfare costs are becoming unsustainable. Back in March, it unveiled plans to cut sickness and disability benefits in order to save £5 billion a year from the welfare budget by 2030. However, the government’s own figures suggested that 250,000 people could be pushed into poverty because of the changes, which led to criticism from many Labour MPs and disability charities.

The threat of rebellion forced a partial u-turn by the government which appeased the vast majority of rebels. Although the remaining rebels failed to pass their wrecking amendment in the end, the fact the government was continuing to negotiate and offer concessions well into the debate on the night of the vote shows that the whips still felt there was a prospect of defeat. This behaviour during the debate is highly unusual and could all have been prevented.

Whenever there is disagreement between the government and its own backbench MPs, the role of the whips becomes even more vital. The whips have an important role in informing backbench MPs of which way the party leadership expects them to vote during divisions in the House of Commons.

However, this is in fact a two-way channel of communication. Whips are also responsible for reporting concerns and dissension among MPs to the chief whip, who then has a duty to report such issues to the prime minister and cabinet.

There has clearly been a breakdown in this two-way channel of communication in the case of the disability benefits cuts. Reports suggest that whips were warning that trouble was brewing to ministers but were being ignored.

How to avoid a repeat incident

A key complaint among Labour backbenchers was that they were not consulted on the proposals before they were announced. As the potential consequences of the changes became clearer, more MPs raised concerns about them.

A lesson for the government here is that adequate groundwork is needed to get MPs on side with policies. That might mean allowing select committees to have more insight into the government’s thinking. It’s notable that select committee chairs were leading figures in this rebellion.

It might also mean making greater use of departmental groups within the Parliamentary Labour Party to allow backbench MPs to feed into discussions at an earlier stage. Crucially, it also means more one-to-one, informal conversations.

All this helps MPs feel like they have a vested interest in the policy and have had their voices heard. If you implement such a safety valve early on, the need for views and frustrations to be expressed so publicly later on in the process is reduced. Instead, in this case, we’ve had Labour backbenchers revealing to the media that, a year into office, they’ve still never even met Starmer.

We have seen a trend in recent years of MPs becoming more focused on their constituency role. This, combined with the large rise in the number of MPs who hold marginal seats (meaning they are at greater risk of losing those seats at the next election) means that they prioritise constituents concerns over the party line. MPs who are worried about holding their seat at the next election have little to lose from threats about losing the whip.

Labour’s position in the polls over recent months has exacerbated this problem. An analysis by the Disability Poverty Campaign Group in April suggested that for dozens of Labour MPs, the number of people claiming the benefits that were to be cut in their constituencies was greater than the size of their majority. In other words, there was a direct line to be drawn between voting for the bill and election loss.

An additional factor that must be considered is that the sheer number of Labour MPs currently in parliament means that the usual incentives for loyalty don’t necessarily apply. Loyalty is often negotiated with promises of ministerial office in the future, but Starmer doesn’t turn over his team often and, in any case, there simply aren’t enough such carrots to dangle in front of everyone when a party has more than 400 MPs.

Labour would also have to win a second term for such promises to be meaningful and that is currently in jeopardy. All this means there are fewer incentives for MPs to play the long game.

What is clear is that Starmer’s approach to party management is not working. Given how the changing nature of politics in the UK, MPs are likely to get a taste for rebellion – particularly if, as happened in this case, rebellions deliver results. This is something any government should seek to avoid.

Clearly there is a need for more groundwork to give MPs a sense of ownership over policy. There is also an argument for the prime minister and senior members of the cabinet to spend more time doing the rounds in the House of Commons tearooms, speaking to the parliamentary party at large and listening to their concerns directly. This might improve parliamentary party relations and keep the lid on future rebellions.

Euro 2025: women’s football has exploded – here’s how it can grow even more

Source: The Conversation – UK – By Christina Philippou, Associate Professor in Accounting and Sport Finance, University of Portsmouth

Aside from victory and sporting glory, the players in the women’s Euro 2025 football tournament are playing for more money than ever before. The prize fund of €41 million (£35 million), to be shared among the 16 participating sides, is more than double what it was last time around.

It’s still a long way off from the prize money on offer to the men’s equivalent tournament (€331 million), but is a clear indication of the continuing rise of interest and investment in women’s football, particularly within England.

The English team’s hosting and victory of the 2022 women’s Euros were rightly credited with providing a massive boost to the game three years ago. But interest in women’s club football was already on the rise, with an almost sixfold increase in revenue between 2011 (the first season of the Women’s Super League (WSL)) and 2019.

Other numbers are encouraging too. Generally, match-day attendances have seen a dramatic rise including for the sport’s second tier (now named WSL2).

Broadcasting income for WSL was up 40% in 2023-24 compared to the previous season. And a new five-year deal with Sky Sports and the BBC, worth £65 million, is worth almost double the previous arrangement.

However, there’s room for improvement.

Research suggests that well-considered scheduling (weekend games are best) can have a marked effect on attendances (as does weather and pricing). And stadium capacity matters too, partly because more people can attend but also because a larger (often iconic) stadium tends to act as an attraction in itself.

For example, Arsenal’s women’s side saw average crowds of just under 29,000 in 2024-25 compared to a WSL average of 6,662. They have the highest revenue from match-day income, with nine games being played at the Emirates stadium last season and all WSL games scheduled to be played there in the next.

Facilities within the stadiums are another concern, as they were traditionally built for mostly male spectators, so do not cater as well to the more female and family demographic of women’s football.

This means, for example, that there are often not enough women’s toilets available, while refreshment options may be geared towards drinkers rather than children. Even the gates seem designed for a steady entry trickle of fans over an hour rather than a mass turnout of time-pressured families arriving just before kick-off.

Some good news on this front is that Brighton and Hove Albion FC are now building a stadium specifically for use by their women’s team, due to be in use by 2027. And Everton have decided to repurpose Goodison Park for use by its women’s side following the men’s move to a new stadium.

Commercial break

But aside from people actually watching the matches, the biggest chunk of income for women’s teams comes from commercial enterprises. And while affiliated teams (those linked to a men’s side) can benefit from sharing a brand, there are also a large number of commercial partners emerging specifically in the women’s game.

Companies selling makeup, baby products, sports bras and period pants are all involved in the business side of women’s football. More will probably follow.

But while commercial and competition success stories are something to celebrate, women’s football still faces challenges. One of the big ones is to do with building a legacy – the idea that just hosting a major tournament should not be the end goal, but something which ensures lasting change and development.

Building a legacy is not straightforward, but after England’s success in Euro 2022, the side used their platform to ensure change on issues including access to football for girls in schools and availability of kit.

As for the club game, attitudes to building a legacy by offering financial support to women’s teams are mixed. Some clubs view the women’s team as different (in terms of marketing, say) but integrated as part of the club (in terms of ticketing and sharing of resources). Others seem to consider a women’s side as good PR or community outreach rather than a genuine commercial opportunity.

In the last couple of years, we have seen both Reading and Blackburn women’s teams withdraw from the WSL2, while Wolves failed to apply for license to the league.

All of those teams mentioned worries over costs. And most women’s teams do lose money.

But men’s teams tend to lose money too, with the majority not only making losses but also being technically insolvent (meaning owners need to pump money in to keep clubs going).

The difference is that women’s football is essentially in a start-up phase, with lots of commercial, broadcasting and match-day potential, as showcased by annual revenue growth rates. In contrast, the men’s football market is a mature one that has been professional for decades, and shows much lower annual revenue growth.

Euro 2025 then, needs to play its part in keeping up momentum. It needs to keep the crowds, the commercial partners, the broadcasters and fans on board and committed.

For while women’s football is connected to men’s football, it is a different business. And celebrating that difference could do the women’s game a world of economic good.

Why investing in climate-vulnerable countries makes good business sense

A new flood barrier is being built to prevent climate-induced Flooding in Chittagong in Bangladesh. amdadphoto/Shutterstock.com

At a coastal port in Chittagong, Bangladesh, something remarkable is underway. With support from a US$850 million (£620 million) investment from the World Bank, engineers are building flood-resistant infrastructure that can survive rising seas and stronger storms. A new 3.7-mile-long barrier will protect people, homes, and trade in one of the world’s most climate-vulnerable regions.

Projects like this do more than save lives. They show why investing in climate
adaptation is one of the smartest financial opportunities of our time. There are plenty of global conferences where leaders discuss climate change and make big
promises. Yet, less than 5.5% of global climate finance actually reaches the countries most at risk. That is not just a failure of fairness. It is a missed chance for real impact.

As the world gathers in Seville, Spain for the fourth international meeting on development financing, the focus must go beyond pledges and shift toward practical, on-the-ground investment in resilience.

At the previous UN climate finance meeting, also held in Seville, leaders focused
on fixing how public money flows through global institutions. But just as important is the need to invest in climate adaptation. This means helping people live with the changes already happening, including more floods, longer droughts, rising seas and intense heat.

While mitigation is about stopping climate change getting worse (by switching to clean energy or protecting forests that absorb carbon, for example), adaptation is about coping with the effects we can no longer avoid. It includes building stronger homes, growing more resilient crops, and improving hospitals and schools so they can keep working during extreme weather. Both approaches are necessary, but adaptation often gets less attention. And less money.

Private investors have already committed large sums to clean energy projects. But they have done much less to support communities on the frontlines of climate change. Many of these countries struggle with limited budgets, complex rules for accessing finance, and a lack of support to develop viable projects. So promising ideas often go unfunded.

That is beginning to change. New tools are helping investors take on less risk and back more projects. These include low-interest loans, partnerships between public and private institutions, and guarantees that reduce the risk of failure.

The Green Climate Fund is the largest source of dedicated climate finance for developing countries. By the end of 2023, it had approved US$13.5 billion in funding, rising to US$51.9 billion when co-financing is included. This money helps unlock adaptation efforts that were previously out of reach.

We can already see progress. In Kenya and Ethiopia, farmers are using drought-resistant seeds to grow more food in changing conditions. In the Caribbean, solar energy is powering schools and clinics in remote communities. And in Bangladesh, the new port infrastructure in Chittagong is protecting a vital economic hub while boosting local businesses.

Working with nature

In coastal areas, restoring mangrove forests can reduce the force of incoming storms, protect biodiversity and support fisheries. The Pollination Group, a climate investment firm, is helping turn “nature-based solutions” like these into projects that attract private finance.

In his previous role as the Prince of Wales, King Charles III launched the Natural Capital Investment Alliance, an initiative that aims to mobilise US$10 billion for projects that restore and protect nature while offering solid financial returns. The alliance also helps investors better understand these kinds of opportunities by creating clearer guidance and standards. This supports the Terra Carta, a charter created by King Charles III that offers a roadmap for businesses to align with the needs of both people and the planet by 2030.

Investors who step into these emerging spaces gain more than financial returns. They build long-term relationships with governments and local communities. They help shape future policy. And they create lasting foundations for growth in places that are ready to lead if given the chance.

Adaptation projects also bring real benefits to people. They improve access to clean water, protect food supplies, create jobs, strengthen education and support healthcare systems. For families already facing climate disruption, these changes are not just improvements. They are lifelines.

By creating stable and welcoming environments for responsible investment, governments can accelerate this shift. By simplifying how money is accessed, international institutions can make it easier for good ideas to become funded projects. Philanthropic groups and development agencies can help build local skills and prepare projects for funding. Private investors can bring capital, innovation and experience.

Investing in climate adaptation is no longer just a moral issue. It is a smart, scalable and necessary response to a changing world.

Why white clothing is a requirement at Wimbledon

Source: The Conversation – UK – By Roger Fagge, Associate Professor in the Department of History, University of Warwick

When Carlos Alcaraz beat Jannik Sinner at the Roland Garros men’s final on June 8 2025, in what is already seen as a classic match, there was some comment on the sartorial choices of the two players.

They both wore Nike tops. Alcaraz’s was collarless, with horizontal blue bordered green and black stripes, and black shorts. Meanwhile Sinner wore a green polo-style shirt with collar, blue shorts and a blue Nike cap. Sinner’s shirt bore more than a passing resemblance to an Irish rugby union top, and was seen by some as somewhat incongruous on a tennis court.

In the women’s final on June 7, meanwhile, Coco Gauff brilliantly defeated Aryna Sabalenka, the number one seed. Gauff wore a custom New Balance kit with a dark blue marbled effect, finished off with a stylish grey leather jacket worn to and from the court. Sabalenka wore a colourful Nike tennis dress.

Technology, design and fashion all play a role in a player’s choice of tennis kit, as does their commercial potential – Sabalenka’s exact dress can be bought from the Nike website. But things are different at the Wimbledon championships, where “almost entirely white” kit is still a requirement.

Founded in 1877, making it the oldest and most prestigious tennis tournament in the world, at Wimbledon, any colour must be limited to a 10mm strip.

White clothing was enforced at Wimbledon from the 19th century, in part because it covered up unwelcome signs of sweat. White clothing was also seen as cooler in the summer heat. But as time went on it became tied in with a sense of history and tradition, and the uniqueness of the Wimbledon tournament. Though there have been some occasional notable revisions.

Many women in the tennis community, including Billie Jean King, Judy Murray and Heather Watson, have argued that women players find white undershorts problematic when they are menstruating. As a result, the All England Club revised the rules in 2023 to allow dark undershorts, “provided they are no longer than their shorts or skirt”.

There had been earlier controversies over clothing at Wimbledon, sometimes over propriety, as in 1949, when Gertrude Moran challenged dress codes with “visible undergarments”. More recently in 2017 Venus Williams was asked to change during a rain break in a match because of visible fuchsia bras straps. The following year, Roger Federer, chasing his eighth Wimbledon title, was asked to change his orange-soled Nike shoes. They all acquiesced.

This history of all-white kits

All-white clothing is also linked to cricket, which shares elements of class and tradition with tennis. Playing in the summer sun meant cricket “whites” were a sensible option. However coloured caps of a player’s county or nation, were allowed by the cricket authorities, and cricket jumpers for the not so sunny days typically had the colours of the team on the v neck.

By 2020 the international Cricket Council (ICC) allowed larger sponsorship on shirts. The move to limited overs games played under floodlights saw the introduction of coloured kit, sometimes displaying a garishness that surpassed football shirts. However Test matches and longer-form cricket like the four-day county championship matches are still played in cricket whites.

And white shirts and kit have played a role in other sports, including football. If white shirts suggest respectability and style, somewhat ironically, the powerful white-clad Leeds side of the mid 1960s-70s, managed by Don Revie, earned the sobriquet “dirty Leeds” for their feisty approach to the dark arts of football. History and tradition matter as much in football as any sport, and fans of a certain age at other clubs, still refer to the Yorkshire club by this moniker.

But that’s enough football, as we’re firmly in Wimbledon season. So break out the Pimm’s, scones and jam, and let’s enjoy the tennis. Thankfully for the traditionalists among us there will be no marbled, green or blue kit on the centre court.

How far is your closest hospital or clinic? Public health researchers explain why Africa needs up-to-date health facility databases

Source: The Conversation – Africa (2) – By Peter M Macharia, Senior postdoctoral research fellow, Institute of Tropical Medicine Antwerp

The lack of reliable information about health facilities across sub-Saharan Africa became very clear during the COVID-19 pandemic. Amid a surge in emergency care needs, information was lacking about the location of facilities, bed capacity and oxygen availability, and even where to find medical specialists. This data could have enabled precise assessments of hospital surge capacity and geographic access to critical care. Peter Macharia and Emelda Okiro, whose research focuses on public health and equity of health service access in low resource settings, share the findings of their recent study, co-authored with colleagues.

What are open health facility databases?

A health facility is a service delivery point where healthcare services are provided. The facilities can range from small clinics and doctor’s offices to large teaching and referral hospitals.

A health facility database is a list of all health facilities in a country or geographic area, such as a district. A typical database should assign each health facility a unique code, name, size, type (from primary to tertiary), ownership (public or private), operational status (working or closed), location and subnational unit (county or district). It should also record services (emergency obstetric care, for example), capacity (number of beds, for example), infrastructure (electricity availability, for example), contact information (address and email), and when this information was last updated.

The ideal method of compiling this list is to conduct a census, as Kenya did in 2023. But this takes resources. Some countries have compiled lists from existing incomplete ones. Senegal did this and so did Kenya in 2003 and 2008.

This list should be open to stakeholders, including government agencies, development partners and researchers. Health facility lists must be shared through a governance framework that balances data sharing with protections for data subjects and creators. In some countries, such as Kenya and Malawi, these listings are accessible through web portals without additional permission. In others, such facility lists do not exist or require extra permission.

Why are they useful to have?

Facility listings can serve the needs of individuals and communities. They also serve sub-national, national and continental health objectives.

At the individual level, a facility list offers a choice of alternatives to health seekers. At the community level, the data can guide decisions like where to place community health workers, as seen in Mali and Sierra Leone.

Health lists are useful when distributing commodities such as bed nets and allocating resources based on the health needs of the areas they serve. They help in planning for vaccination campaigns by creating detailed immunisation microplans.

By taking account of the disease burden, social dynamics and environmental factors, health services can be tailored to specific needs.

Detailed maps of healthcare resources enable quicker emergency responses by pinpointing facilities equipped for specific crises. Disease surveillance systems depend on continuously collecting data from healthcare facilities.

At the continental level, lists are crucial for a coordinated health system response during pandemics and outbreaks. They can facilitate cross-border planning, pandemic preparedness and collaboration.

During the COVID-19 pandemic, these lists informed where to put additional resources such as makeshift hospitals or transport programmes for adults over  60 years of age.

The lists are used to identify vulnerable populations at risk of emerging pathogens and populations that can benefit from new health facilities.

They are important when it comes to making emergency obstetric and newborn care accessible.

What goes wrong if you don’t have them?

Many problems arise if we don’t know where health facilities are or what they offer. Healthcare planning becomes inefficient. This can result in duplicate facility lists and the misallocation of resources, which leads to waste and inequities.

We can’t identify populations that lack services. Emergency responses weaken due to uncertainty about where best to move patients with specific conditions.

Resources are wasted when there are duplicate facility lists. For example, between 2010 and 2016, six government departments partnered with development organisations, resulting in ten lists of health facilities in Nigeria.

In Tanzania, over 10 different health facility lists existed in 2009. Maintained by donors and government agencies, the function-specific lists didn’t work together to share information easily and accurately. This prompted the need for a national master facility list.

What needs to happen to build one?

A comprehensive list of health facilities can be compiled through mapping exercises or from existing lists. The health ministry should take responsibility for setting up, developing and updating this list.

Partnerships are crucial for developing facility lists. Stakeholders include donors, implementing and humanitarian partners, technical advisors and research institutions. Many of these have their own project-based lists, which should integrate into a centralised facility list managed by the ministry. The health ministry must foster a transparent environment, encouraging citizens and stakeholders to contribute to enhancing health facility data.

Political and financial commitment from governments is essential. Creating and maintaining a proper list requires significant investment. Expertise and resources are necessary to keep it updated.

A commitment to open data is a necessary step. Open access to these lists makes them more complete, reliable and useful.

Moon mining is getting closer to reality: Why we need global rules for extracting space resources

In science-fiction stories, companies often mine the moon or asteroids. While this may seem far-fetched, this idea is edging closer to becoming reality.

Celestial bodies like the moon contain valuable resources, such as lunar regolith — also known as moon dust — and helium-3. These resources could serve a range of applications, including making rocket propellant and generating energy to sustaining long missions, bringing benefits in space and on Earth.

The first objective on this journey is being able to collect lunar regolith. One company taking up this challenge is ispace, a Japanese space exploration company ispace that signed a contract with NASA in 2020 for the collection and transfer of ownership of lunar regolith.

The company recently attempted to land its RESILIENCE lunar lander, but the mission was ultimately unsuccessful. Still, this endeavour marked a significant move toward the commercialization of space resources.

These circumstances give rise to a fundamental question: what are the legal rules governing the exploitation of space resources? The answer is both simple and complex, as there is a mix of international agreements and evolving regulations to consider.

What does the international legal system say?

The cornerstone legal instrument for space activity is the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies, more commonly referred to as the Outer Space Treaty.

While space law is often considered a novel legal field, the Outer Space Treaty dates back to 1967, making it more than half a century old.

Space activities have exponentially evolved since the treaty’s adoption. In the 60 years following the launch of Sputnik 1 — the first satellite placed in orbit — less than 500 space objects were launched annually. But since 2018, this number has risen into the thousands, with nearly 3,000 launched in 2024.

Because of this, the treaty is often judged as inadequate to address the current complexities of space activities, particularly resource exploitation.

A longstanding debate centres on whether Article II of the treaty, which prohibits the appropriation of outer space — including the moon and other celestial bodies — also prohibits space mining.

The prevailing position is that Article II solely bans the appropriation of territory, not the extraction of resources themselves.

We are now at a crucial moment in the development of space law. Arguing over whether extraction is legal serves no purpose. Instead, the focus must shift to ensuring resource extraction is carried out in accordance with principles that ensure the safe and responsible use of outer space.

International and national space laws

A significant development in the governance of space resources has been the adoption Artemis Accords, which — as of June 2025 — has 55 signatory nations. The accords reflect a growing international consensus concerning the exploitation of space resources.

Notably, Section 10 of the accords indicates that the exploitation of space resources does not constitute appropriation, and therefore doesn’t violate the Outer Space Treaty.

Considering the typically slow pace of multilateral negotiations, a handful of nations introduced national legislation. These laws govern the legality of space resource exploitation, allowing private companies to request licenses to conduct this type of activity.

To date, six nations have enacted this type of legislation: the United States in 2015, Luxembourg in 2017, the United Arab Emirates in 2019, Japan in 2021, Brazil in 2024 and most recently, Italy, which passed its law on June 11, 2025.

Among these, Luxembourg’s legal framework is the most complete. It provides a series of requirements to provide authorization for the exploitation of space resources. In fact, ispace’s licence to collect lunar regolith was obtained under this regime.

The rest of the regulations usually tend to limit themselves to proclaiming the legality of this activity without entering into too much detail and deferring the specifics of implementation to future regulations.

While these initiatives served to put space resources at the forefront of international forums, they also risk regulatory fragmentation, as different countries adopt varying standards and approaches.

What does the future hold?

Recognizing the need for a co-ordinated global approach, the United Nations Committee on Peaceful Uses of Outer Space created a Working Group on Legal Aspects of Space Resource Activities. Its mandate is to develop a set of general principles to guide the development of the activity.

In May 2025, the chair of the working group, Steven Freeland, presented a draft of recommended principles based on input from member states.

These principles reaffirm the freedom of use and exploration of outer space for peaceful purposes, while introducing rules pertaining to the safety of the activities and their sustainability, as well as the protection of the environment, both of Earth and outer space.

The development of a legal framework for space resources is still in its early stages. The working group is expected to submit its final report by 2027, but the non-binding nature of the principles raises concerns about their enforcement and application.

As humanity moves closer to extracting and using space resources, the need for a cohesive and responsible governance system has never been greater.

Does eating cheese before bed really give you nightmares? Here’s what the science says

Have you heard people say eating cheese before bed will cause you to have vivid dreams or nightmares?

It’s a relatively common idea. And this week, a new study has landed this suggestion back in the spotlight.

But is it true? Let’s unpack the evidence.

A gouda night’s sleep?

Canadian researchers recently investigated this idea in a sample of 1,082 undergraduate psychology students. The students completed a survey, which included questions about how they perceived their diet influenced their sleep and dreams.

Some 40% of participants reported certain foods impacted their sleep, with 25% of the whole sample claiming certain foods worsened their sleep, and 20% reporting certain foods improved their sleep.

Only 5.5% of respondents believed what they ate affected the nature of their dreams. But many of these people thought sweets or dairy products (such as cheese) made their dreams more strange or disturbing and worsened their sleep.

In contrast, participants reported fruits, vegetables and herbal teas led to better sleep.

This study used self-reporting, meaning the results rely on the participants recalling and reporting information about their sleep and dreams accurately. This could have affected the results.

It’s also possible participants were already familiar with the notion that cheese causes nightmares, especially given they were psychology students, many of whom may have studied sleep and dreaming.

This awareness could have made them more likely to notice or perceive their sleep was disrupted after eating dairy. In other words, the idea cheese leads to nightmares may have acted like a self-fulfilling prophecy and results may overestimate the actual likelihood of strange dreams.

Nonetheless, these findings show some people perceive a connection between what they eat and how they dream.

While there’s no evidence to prove cheese causes nightmares, there is evidence that does explain a link.

The science behind cheese and nightmares

Humans are diurnal creatures, meaning our body is primed to be asleep at night and awake during the day. Eating cheese before bed means we’re challenging the body with food at a time when it really doesn’t want to be eating.

At night, our physiological systems are not primed to digest food. For example, it takes longer for food to move through our digestive tract at night compared with during the day.

If we eat close to going to sleep, our body has to process and digest the food while we’re sleeping. This is a bit like running through mud – we can do it, but it’s slow and inefficient.

Cheese can be particularly challenging to digest at night because of high concentrations of fat and protein, which slows down our digestion.

If your body is processing and digesting food instead of focusing all its resources on sleep, this can affect your shut-eye. Research has shown eating close to bedtime reduces our sleep quality, particularly our time spent in rapid eye movement (REM) sleep, which is the stage of sleep associated with vivid dreams.

People will have an even harder time digesting cheese at night if they’re lactose intolerant, which might mean they experience even greater impacts on their sleep. This follows what the Canadian researchers found in their study, with lactose intolerant participants reporting poorer sleep quality and more nightmares.

It’s important to note we might actually have vivid dreams or nightmares every night – what could change is whether we’re aware of the dreams and can remember them when we wake up.

Poor sleep quality often means we wake up more during the night. If we wake up during REM sleep, research shows we’re more likely to report vivid dreams or nightmares that we mightn’t even remember if we hadn’t woken up during them.

This is very relevant for the cheese and nightmares question. Put simply, eating before bed impacts our sleep quality, so we’re more likely to wake up during our nightmares and remember them.

Can I still have brie before bedtime?

Don’t panic – I’m not here to tell you to give up your cheesy evenings. But what we eat before bed can make a real difference to how well we sleep, so timing matters.

General sleep hygiene guidelines suggest avoiding meals at least two hours before bed. So even if you’re eating a very cheese-heavy meal, you have a window of time before bed to digest the meal and drift off to a nice peaceful sleep.

How about other dairy products?

Cheese isn’t the only dairy product which may influence our sleep. Most of us have heard about the benefits of having a warm glass of milk before bed.

Milk can be easier to digest than cheese. In fact, milk is a good choice in the evening, as it contains tryptophan, an amino acid that helps promote sleep.

Nonetheless, we still don’t want to be challenging our body with too much dairy before bed. Participants in the Canadian study did report nightmares after dairy, and milk close to bed might have contributed to this.

While it’s wise to steer clear of food (especially cheese) in the two hours before lights out, there’s no need to avoid cheese altogether. Enjoy that cheesy pasta or cheese board, just give your body time to digest before heading off to sleep. If you’re having a late night cheese craving, opt for something small. Your sleep (and your dreams) will thank you.

AI-powered assistive technologies are changing how we experience and imagine public space

AI-powered assistive devices, like hearing aids, are changing how the people who use them experience public space. (Shutterstock)

New applications and the integration of artificial intelligence (AI) with wearable devices are changing the way users interact with their environments and each other. The impacts and reach of these new technologies have yet to be fully understood.

Connections between technologies and bodies is not a new thing for many disabled persons. Assistive technologies — tools and products designed to support people with disabilities — have played a part in mitigating built and institutional barriers experienced by disabled persons for decades.

While not strictly considered assistive, immersive and wearable technologies have the potential to change the relationship between disabled users and their experience of place.

For example, Ray-Ban’s Meta glasses use AI to describe what the cameras are capturing using the Be My Eyes app. Using OpenAI’s large language model, ChatGPT, this effectively turns a user’s smart phone into a vision assistant.

Beyond wearables, some technologies are more closely tied to or integrated with the body. Examples include brain-computer interfaces, AI-enabled prosthetics and bone-anchored hearing aids.

The availability and production of environmental data from these technologies may impact how we relate to each other, how we move through and understand space, and how we engage with the physical environment around us at any given moment.

We’re at a critical juncture where AI-enabled technologies used by individuals may profoundly impact our urban futures.

What happens, for example, when wearables make any “place” a digital work or play place? What does a largely private-sector, consumer-driven, AI-enabled digital intervention into a city’s spaces mean for planning, zoning and taxation? What are the environmental costs of the global AI project?

And crucially, who gets to participate in this digital reimagining?

AI and the city

While access can be challenging — wearables are often costly — ableist thinking regarding the use of technology to render invisible Blind and/or Deaf people and culture is also a problem. Some people might naively assume that all Blind and Deaf people are universally seeking a bio-technological “miracle.”

There are also other challenges: how a technology captures or describes its data may not match up to a user’s pre-existing sense of place. Moreover, access to tech can produce some unintended consequences, including the erosion of in-person community building among disabled people.

Hearing loss of some kind affects around 1.5 billion people: I am one of those people. I am a disability studies scholar who wears behind-the-ear hearing aids to augment my hearing experience.

My hearing aids use AI and machine learning to sense and adjust my sound environment. They help me cope with the ways in which the places of my everyday life — such as my home or the lecture hall — are generally configured for people without hearing loss.

When I use my hearing aids, I find that the city has never sounded so wonderful, and yet sometimes irritatingly loud. The sound of birds is one thing; the grinding sound of a breaking subway is another entirely.

Cumulative exposure to noisy indoor and outdoor places of the city poses auditory health risks, such as noise-induced hearing loss or tinnitus, and can contribute to poor health more broadly. I have to be careful about ongoing noise exposure, and by adjusting the volume of my hearing aids, I can turn down the city when I want to.

Future bodies and urban futures

AI-powered technologies can exacerbate issues of access, privilege and freedom of movement. This happens both through who is able to purchase and use devices, as well as through data and their applications. Data may be biased in terms of race, gender, sexuality and disability.

Scientific research and media representations tend to highlight the benevolent possibilities of technologies for “repairing” bodies conceived as being functionally medically deficient.

Much less is said about disabled persons controlling the narrative, taking up key roles in the messy terrain of AI, machine learning and data governance, and in the planning and design of future cities.

Digital modelling

We are also witnessing growing interest in the digital twinning — creating highly accurate digital models — of everything from human hearts to entire cities.

Whether rendered at the scale of the body or city, the motivation for twinning appears centred on planning and performance optimization — a quest for perfection. Like any model, we are dealing with an abstraction from reality. City twins seem to fail to capture many of the fine grain environmental barriers experienced by disabled persons.

Ownership limits

Not everyone can, should or wishes to be technologically “assisted” or augmented. There are medical, identity and culture, affordability, legal, moral and ethical concerns.

Other issues raised by brain-computer interface research, for example, include concerns about legal capacity and ownership of the self, including ownership of device-generated data.

In a study on the impact of neural technologies, researchers shared the legal repercussions relating to two disabled people deprived of voting rights in Spain. The person who recovered the ability to communicate autonomously using their finger and a computer had their rights restored, while the other, who used a human intermediary, did not.

Legal questions also arise regarding how liability is assigned when augmented bodies are injured or cause injuries to others.

Where does the person end and the technology begin, and vice versa? Who gets to decide?

Future technologies

As the use of AI and assistive technologies increases in everyday urban life, we will need to address these questions sooner rather than later.

And if disabled persons are not adequately involved in these discussions and decisions, then cities will be less — rather than more — accessible.
