Brazil’s Zebu cattle, or “supercows” are bred for size, strength, and meat quality. Every year the animals are showcased at ExpoZebu, Brazil’s premier cattle fair. These animals are preened, pampered, and prized, before being sold for millions for their genetic material.

Zebu cattle were not always part of Brazil’s landscape. After being imported from India in the late 19th century, farmers found their resilience to heat, pests, and poor pasture made them ideal for Brazil’s expanding cattle frontier.

Thanks to decades of selective breeding and low-cost pasture-based farming, Brazil is now the world’s largest beef exporter, and demand is only rising.

Despite its economic success and domestic popularity, Brazil’s beef has a significant environmental cost due to its emissions and links to deforestation. However, their genetic material has the potential to be used around the world to make cattle more resilient to climate change.

Ahead of last year’s US Presidential elections, Donald Trump was asked if he would defend China against Taiwan, he responded that Taiwan should pay the US for protection from China. Taiwan is a self-governing island, claimed by Beijing and whilst Taiwan is not formally recognised by the US, they do remain the island’s most important security partner. Taiwan manufactures over ninety percent of the world’s most advanced semiconductor chips, which makes some American industries heavily dependent on trade links with the island. But official US policy towards Taiwan is one of ‘strategic ambiguity’. So when the US Secretary of Defence, Pete Hegseth recently warned of China posing an ‘imminent’ threat to Taiwan, whilst at the same time urging Asian countries to boost defence spending and work with the US to deter war, it raised the issue of how far America would be prepared to go to defend Taiwan. China in response accused the US of being the ‘biggest troublemaker’ for regional peace. The US has only just agreed a truce on trade tariffs with China and President Trump’s immediate attention has shifted onto issues in the Middle East, so if Pete Hegseth’s warning is valid, how far up the list is Taiwan in terms of Trump’s foreign policy priorities.

The Strait of Hormuz remains one of the most important energy corridors in the world. It is the only sea route from the Persian Gulf to the open ocean, it serves as the primary maritime route for oil exports from the Gulf. Any disruption to traffic through the strait would have implications for oil markets and regional stability.

While some Gulf states have developed pipelines to bypass the strait, the volume of oil transported by sea is far greater, and for many countries, including key Gulf exporters, the waterway is essential to maintaining trade. China is the largest buyer of oil that travels through the strait, making it particularly exposed to any disruption.

Iran itself relies on the Strait of Hormuz to sell its oil and any blockage of the route would likely damage Iran’s own economy and could strain relationships with regional neighbours.

Despite past threats to close the Strait of Hormuz, the waterway has remained open, including during the tanker wars of the 1980s, but any disruption could have a big impact on global oil supplies.

During a speech to the Spanish parliament earlier this year, the country’s Prime Minister Pedro Sanchez claimed there’s one thing that would guarantee lasting peace in Europe.

His idea is the creation of a new army drawn from the 27 countries whose governments already work together as members of the European Union.

The concept isn't a new one - and NATO already exists, the military alliance which includes EU member states and other European countries.

But talk of a new military force is reappearing as the continent becomes more vulnerable to threats. Its ally the US is increasingly unreliable and unpredictable too.

Other European leaders are also backing the idea

This week we’re asking - “Are we closer to a European army?”

The creation of a landmark gene editing drug used to treat a baby with a rare genetic mutation which could help transform personalized medicine. Blood tests showed baby KJ had sky-high levels of ammonia, a toxic substance the body usually expels. The root cause was his genes - or more particularly a specific gene mutation. The race was on to try and treat him before his condition took a firm hold. His doctors came up with a radical solution - for the first time ever, they designed and applied a gene-editing drug in record time, specifically for him. Have we seen breakthrough in preventing genetic diseases? With Fyodor Urnov, a professor in the Molecular and Cell Biology Department at the University of California, Virginijus Šikšnys professor at the Life Science Center of Vilnius University, Waseem Qasim from the UCL Institute of Child Health in Great Ormond Street Hospital in London and Jennifer Doudna, Professor, University of California, Berkeley and founder of the Innovative Genomics Institute.

The economic fortunes of the Southern Africa country of Botswana were transformed back in the mid 1960s when shortly after gaining independence from Britain, its first diamond mine was discovered. A partnership with the world’s biggest diamond firm DeBeers ensured Botswana’s diamonds gained global attention and with some of the world’s biggest diamonds been mined in the country, it now ranks just below Russia in terms of its importance in the industry. But post pandemic, the global market has seen a shift in demand for mined diamonds, with consumers in countries like China, who accounted for around thirty percent of global demand, falling away.

Another reason for this shift is the emerging popularity of lab grown diamonds. Originally used in industrial machinery, lab diamonds are now been refined for the jewellery market at a fraction of the price of mined diamonds, with the majority of consumer interest coming from the United States. Botswana has been trying to ride this wave with a policy of diversification, to allow it to generate more export revenue. But its new Government, who have only been in power since October last year, are dealing with a large budget deficit not helped by the low level of diamond revenues. It faces a hard task in trying to revive demand for mined diamonds across the global market. So, on this week’s Inquiry, we’re asking ‘Are diamonds forever in Botswana?’

Fungal diseases are becoming more common, more dangerous, and more difficult to treat. There’s concern that they may cause the next global pandemic.

Rising global temperatures, better survival rates for vulnerable patients, and increased medical interventions contribute to the rise in fungal infections. Access to effective diagnostics and treatment remains limited, with significant disparities between high and low-income countries.

Treating fungal infections is becoming more challenging as they build resistance to the drugs used to treat them. New therapies are being developed, including treatments that disrupt fungal DNA replication or interfere with essential proteins, offering some hope for long-term control.

A domestic rice shortage in Japan has caused supermarket shelves to empty and prices to double. Rice is more than a staple food in Japan—it carries deep cultural, historical and even spiritual significance.

The rice crisis highlights broader weaknesses in Japan’s economy. Japan imports over half of its food and has experienced persistent inflation. The country’s economic resilience is being tested by supply chain pressures, demographic shifts, and increased trade tensions.

Efforts to address the shortage have focused on auctioning rice reserves, but underlying economic challenges persist.

“Measles is back, and it’s a wake-up call,” proclaimed one regional director from the World Health Organisation who went on to add, “without high vaccination rates, there is no health security.”

Measles is a childhood disease which can be deadly. We’ve been successfully vaccinating against it for decades. So much so that many younger physicians have never seen a child with the disease. But recently, the recorded number of cases has been rising - and this is a global trend.

Measles is one of the most contagious viruses known to man. In an unvaccinated population it will spread like wildfire. So what’s behind the rapid rise of measles cases around the world? According to one of our expert witnesses it comes down to three Cs: complacency, convenience and confidence.

In this edition of the Inquiry, Sandra Kanthal looks into what’s causing the rise in measles cases around the world and asks how this trend can be reversed.

Serbia’s citizens have been protesting for over six months, taking part in demonstrations around the country in reaction to their government’s alleged corruption. Though the country’s president, Aleksandar Vučić, has attempted to appease them, the movement shows no sign of slowing down.

Situated in the Western Balkans, Serbia has had a long history of conflict; from the Ottoman Empire to the dissolution of Yugoslavia, but the ongoing civil unrest comes at a crossroads moment for President Vučić. Serbia is awaiting approval to join the European Union yet remains closely tied with the Kremlin.

As the Serbian government seeks to solidify its place in the world, protestors continue their calls for transparency and accountability. This week on The Inquiry we ask “Will Serbia’s mass protests unseat the president?”

Scientists at a bio-technology firm made headlines when they announced the “de-extinction” of the dire wolf, a species of wolf that went extinct on Earth over 10,000 years ago. Colossal Biosciences examined DNA from ancient dire wolf fossils and used it to create wolf puppies with traits of the extinct species. The gene editing technology sparked curiosity around the world, and although the new wolves were not exact replicas of the originals they had similar traits. The development raises serious questions about what de-extinction really means.

Mass extinctions have shaped the history of life on Earth, and nature has adapted across the millennia, but with almost half of all species already in decline, including some frogs, how seriously is de-extinction technology being taken?

Earlier this month President Trump announced radical new taxes on foreign imports amounting to what he described as ‘Liberation Day' for the United States. It was a promise he made to American voters during last year’s election campaign but the scale of the tariffs caught many countries by surprise.

Global financial markets plunged as investors braced themselves for a shock to the flow of international trade. Faced with prolonged market turmoil, within days the US president paused most of his plans.

A to-and-fro between Washington and Beijing has left many world leaders confused who to side with, as many look towards the White House wondering if there is a detailed plan at the heart of these unprecedented few weeks.
