The running shoe industry is worth around 50 billion dollars across the world, with more and more of us taking part in the sport. With more popularity comes more competition, so what are brands doing to keep consumers interested? We ask the chief marketing officer at Swiss sportswear company, ON, and find out how it helps sales when a top athlete wears their shoes. And as the debate around 'super shoes' rumbles on, are they really worth the expensive price tag? US marathon winner Kellyn Taylor tells us about the pros and cons of carbon plated shoes - which played a big role in marathon records being smashed in 2023.

It's widely recognised that we are bombarded with fast-paced imagery in the modern world, whether it's social media videos, or digital billboards in city spaces.

But there has been a similar explosion in sound, says advertising entrepreneur Michele Arnese. He thinks brands can only compete with the help of artificial intelligence (AI).

Dougal Shaw speaks to the Italian tech entrepreneur who trained as a classical musician, but founded an advertising company that helps companies stand out with distinctive sounds.

Semiconductors hit the news during the Covid-19 pandemic, as issues with supply chains led to shortages of cars and soaring prices.

Since then, geopolitical tensions have impacted the industry. 90% of the world's most advanced chips are made by TSMC in Taiwan. Now, countries all over the world are investing billions of dollars into the industry, so that manufacturing of these chips can happen in more places and alleviate some of the problems supply chains have faced in the last few years.

In today’s episode, we visit a new semiconductor fabrication plant in the UK - the first to develop a low-cost, flexible semiconductor, as companies, and nations, race to diversity the industry.

The Caribbean island imports around 90% of its food and by law only US ships can be used to transport it – which pushes up the price.

We speak to islanders who think that needs to change, and are pushing for Puerto Rico to become more self sufficient.

Weather events like Hurricane Maria, which left many without power and water for months, have brought the issue to the forefront once again.

We meet a new generation who are leading the way, using new technology to try and make it easier, and cheaper, for people to buy local and rely less on imports.

Almost 60% of the world’s population live in cities. And this trend is expected to continue - by 2050 nearly 7 of 10 people will live in urban environments.  

Although more than 80% of global GDP is generated in cities, there are challenges: increasing carbon emissions and environmental pollution, traffic congestion and urban vulnerability, exposed by natural disasters such as floods and storms.

The creation of a digital twin - a digital representation of a real city, infrastructure or even a whole country - could help decision-makers simulate real situations, allowing them to make better decisions. Situations like floods and other extreme weather events.

We look into the technology and find out what the benefits and limitations are...

And the former foreign minister of Tuvalu, Simon Kofe, explains how climate change has forced his country to consider preserving their whole statehood and culture in the metaverse.

Twice in 2023, the American government faced the prospect of having to shut down because politicians in congress couldn’t agree on a budget to fund it. Each time, a shutdown was narrowly averted – by last minute, short-term deals.

Now, a third deadline is looming in mid-January. It leaves politicians – with fierce disagreements over what services the government should pay for, and how – little time to reach an agreement.

We look at the impact of this uncertainty on businesses, and ask, in an election year, what can be done to bring the chaos to an end?

How easy is it to open a bank account in your country?

Around the world, 1.4 billion people can’t get a bank account, and two-thirds of them are in low and middle income countries.

People from migrant communities also struggle to access formal banking services.

We hear from 19 year-old Josue Calderon. Originally from El Salvador, he arrived in the United States when he was 16. He tells Sam Fenwick about the challenges of only being able to use cash when he first arrived in the US.

Sam also speaks to BBC World Service listeners about their experiences of opening a bank account.

The use of these endlessly flexible 3D images is increasing rapidly.

Not just in entertainment, but in medicine, education, design, defence and more.

Holograms trick the brain into seeing something in 3D when it’s really just a projection, allowing us to feel immersed in something – whether it’s an atom, or a cityscape.

We talk to companies developing this fast advancing technology and ask – will we be living in a holographic future?

Alastair Leithead and his wife Ana moved to Portugal during the Covid pandemic. They live off-grid, meaning they have no access to mains electricity or water supplies. They also have to manage their own waste water and sewage.

Now the former BBC correspondent is embarking on an ambitious project to build and run a hotel, meaning their solar powered utilities will not only have to work for them, but also paying guests.

In the first of a two part series, we're in the Alentejo region where people are buying land and empty properties in an area without power or water supply.

Former BBC correspondent Alastair Leithead is one of them - he has moved there with his wife, and is trying to build and run a hotel. He travels around the region and speaks to his neighbours about their experiences.

Plus - what do local people think of this influx of foreigners coming to live off-grid?
