The Inquiry gets beyond the headlines to explore the trends, forces and ideas shaping the world.

The Inquiry

Extreme heatwaves are becoming more frequent across the globe, not only in countries used to cooler climates, but also in those already familiar with significantly hotter temperatures. 

Intense heat can have an impact on the human body, from heat stroke to dehydration to skin damage. Economies can suffer as drought conditions impact farming communities. Built up urban areas can exacerbate the temperatures caused by heatwaves. And it can further expose already existing inequalities in society. 

There is advice out there on how to protect ourselves. There are tried and tested models of sustainable farming. Some urban spaces are being redesigned to accommodate heat extremes, and some major cities are taking action to address the imbalances caused by extreme heat. But do they all go far enough Can we live with extreme heat?’

Joining us on the programme are Prof Ollie Jay, director of Heat and Health Research Centre, University of Sydney, Australia; Lindiwe Majele Sibanda, animal scientist, chairperson of the Council of the National University of Science & Technology, Zimbabwe; Winston Chow, co-chair, IPCC Working Group II, professor of urban climate, Singapore Management University and Diana Liverman, professor of geography, University of Arizona, Tucson, USA.

Can we live with extreme heat?

Gold has been prized throughout history for its value and its beauty, which has also made it attractive to those prepared to exploit this precious metal for their own ends. The European Union recently banned the purchase, import and transfer of gold from Sudan, one of Africa’s largest gold producers, saying it had become a key source of financing for the country’s civil war. 

And in other parts of the world where there are gold reserves, there can be similar exploitation. Many artisanal and small-scale miners are vulnerable to organised crime syndicates who find the risks of gold mining lower compared to those of drug trafficking. 

And illicit gold is much easier to launder into the legal market, because it can be melted down with legitimate sources of gold and smuggled across borders, making its origins much harder to trace. 

But the challenge for governments trying to enforce the law is how to protect those at the bottom of the chain and provide them with sustainable alternatives to illicit gold mining, whilst clamping down on the criminal groups behind the operation. So, can the illicit gold trade be stopped?’

This week, our panel includes Campbell Harvey, professor of finance, Duke University, Durham, North Carolina, USA; Dr Dan Watson, research associate, International Institute for Strategic Studies, London, UK; Bram Ebus, consultant with International Crisis Group, founder and co-director Amazon Underworld, Bogotá, Colombia and Louis Maréchal, senior adviser on minerals and extractives, OECD, Paris, France.

Gene therapy has changed what is possible for people living with sickle cell disease. New treatments have shown that the condition can be successfully treated. But the therapy is costly and available to only a small number of patients. 

Millions of people around the world still rely on early diagnosis and preventative medicines, with access to basic care remaining a challenge in many places, including sub-Saharan Africa, which has almost 80% of global sickle cell cases. Are we closer to gene therapy for sickle cell disease being accessible?

We speak to Dr Natasha Archer, director of the Sickle Cell Program at the Dana-Farber/Boston Children's Cancer and Blood Disorders Center, US; Dr Alexis Thompson, paediatric haematologist at the Children's Hospital of Philadelphia and a professor of paediatrics at the University of Pennsylvania, US; Dr Leon Tshilolo, professor of paediatrics and haematology at the University of Mbuji-Mayi, DR Congo and Prof Baba Inusa, consultant paediatrician in the School of Life Course & Population Sciences at King's College London, UK

Last year Kenya’s President William Ruto established a task force to investigate the escalating cases of gender-based violence including femicide. The task force travelled around the country gathering information and at the beginning of this year published its recommendations, which are now being debated in parliament. One of those recommendations is the legal recognition of femicide as a standalone crime. 

UN Women, the United Nations agency which promotes the empowerment and rights of girls and women, have been working with grassroots organisations in Kenya on male engagement strategies, to change perceptions of the role of men and women. But the UN Women’s representative in Kenya, acknowledges that challenges remain. 

In the meantime, women continue to march in protest and the country waits to see if President Ruto will implement the task force recommendations. So, is Kenya serious about ending femicide?

Flesh-eating parasitic flies have been found in the US state of Texas for the first time in decades. Known as the New World Screwworm, officials have now put plans in place to try and contain its spread. The fly feeds off warm-blooded animals, like cattle, dogs and horses, but if detected early enough, with treatment, the animals can make a full recovery. It can also infest humans, but human deaths are rare and it poses no food safety issues. 

The New World Screwworm is not a new problem; it is considered endemic in South America and some parts of Central America, towards South America. But despite the United States declaring itself screwworm free in the 1960s, the country has since seen several outbreaks. Officials have been tracking this latest case since late 2024. 

To date, the most widely used method to try and control the spread of the screwworm is the Sterile Insect Technique, whereby millions of flies are hatched and exposed to radiation, before they are released into the wild. And the idea here is that as the females only mate once in a lifetime, any eggs they lay will be unfertilised and will not hatch. There is currently only one facility hatching these flies in operation and there are not enough sterile flies being produced. In addition, there is a concern over a lack of knowledge among new veterinary recruits on how to deal with a problem that many may be experiencing for the first time. So, can the New World Screwworm be stopped?

This year, technology has more influence in officiating sports than ever before.

At the men's World Cup, the role of virtual assistant referee technology (VAR) has been extended to include two more on-pitch scenarios while in tennis, umpires use electric line calling systems (ELC) to make final decisions.

Both bits of kit aim to improve the accuracy. It’s become easier to consider match-defining moments through these tracking and review systems’ specialised cameras. But, this information takes human officials valuable time to analyse.

Football fans criticise VAR for this reason, saying it delays match momentum. Top ranking tennis players Aryna Sabalenka and Alexander Zverev have also complained as these systems are not yet infallible. If technology is as imperfect as a human referee or umpire and can interrupt the fan experience too, why do elite sports rely on it?

A new directive strives to narrow the 11% hourly wage gap between men and women in the EU.

Around the world, the gender pay gap has been shrinking as women gain access to higher education and better employment opportunities. Though varied hours, industries and care responsibilities make this inequality a difficult problem to tackle with one universal policy.

Member states have just passed their deadline to implement measures that will hold employers to account for pay disparities in the workplace so will pay transparency solve the persistent gap?

In May 2026, the World Health Organization declared an Ebola outbreak in western Africa a public health emergency of international concern. Within days, hundreds of cases had been recorded in the Democratic Republic of Congo, raising fears that the virus could spread further across the region.

Ebola has been causing outbreaks for nearly 50 years, but despite advances in vaccines and treatments, the disease continues to return. But why is it so difficult to treat and contain?

Why does Ebola keep coming back?

In 2001, Portugal decriminalised the possession and use of all illicit drugs. It was a move designed to mitigate the country’s public health crisis, which at the time meant Portugal had one of the worst rates of overdose deaths in Europe, as well as the highest rate of HIV among drug users. Whilst drugs remained illegal, users did not receive a criminal record but were instead referred to rehabilitation and treatment programmes. It was an approach that proved so successful, that it has remained in place for a quarter of a century. 

But just over 10 years after its introduction, Portugal’s drugs policy started to come under strain as the country’s economic crisis and subsequent austerity measures led to budget cuts for drug services. More recently the rising cost of living has diverted people’s attention from investment in this field. On top of this, the trafficking of cocaine and newer substances into the country along with changing demographics is putting decriminalisation under strain.

Is Portugal’s drugs policy in need of reform?

At the beginning of this year Bulgaria, considered as one of the poorest countries in the European Union, became the latest to officially join the eurozone. Bulgaria’s legal tender since 1881 had been the lev, but since the mid-1990s it had been pegged to other European currencies, first to the German deutschmark and now to the euro. But it remains to be seen if the country’s economic policy can take advantage of the opportunities that joining the single currency can afford, in terms of trade and economic development. 

Monetary unions are not a new concept, some like the Scandinavian monetary union date back to the 19th Century, involving Denmark, Sweden and Norway. It established a fixed exchange rate system based on the gold standard, whilst member countries still had their own currencies before it was gradually dissolved from the outbreak of World War One onwards. 

Today, the biggest monetary union is the eurozone, used by around 358 million people across 21 European Union countries. It has one monetary authority for all the members and a standardised currency and coinage. 

And now the Economic Community of West African States, known as Ecowas is actively planning a monetary union with a common currency called the eco and pegged to the euro. The ambition is for greater economic sovereignty and regional economic integration. 

But with the US dollar as the world’s dominant global reserve currency, even though it is not part of a global monetary union, is there an argument for one currency across all borders and if so, what should it be?
