What’s the deal with the metaverse?
So what is the metaverse really? Following a montage of BBC World Service listeners’ responses and opinions, contributing expert Ghislaine Boddington will shed light on this question. As it turns out, while there are current examples of virtual worlds, the metaverse is still being formed. Predicting exactly what it will be like is harder than one might think.An afternoon in Altspace
What does it feel like to be in the metaverse? Reporter Chris Berrow strapped on his VR headset and spent some time in AltspaceVR to find out. From holding a virtual cat to doing yoga class, his experience turned out to be stranger than he had anticipated.Future implications
If the metaverse becomes as popular as some predict, where are we headed? In a live discussion with tech futurist and metaverse expert Cathy Hackl, video game writer Colin Harvey, and our very own Ghislaine Boddington, we discuss the big issues on the horizon. Who will be creating it and who will have access? Could this lead to harvesting of biometric data?

Community Networks: Connecting the unconnected
Across the North American continent, there is a stark difference in the availability of internet to different communities. Tribal lands are typically remote, rural and rugged landscapes, and often have very patchy, or non-existent internet connectivity. Dr Traci Morris explains why such a digital divide exists and how tribes are working together, both within their communities and with each other, to create and gain access to communications networks. Digital Deras connecting farmers in rural Pakistan
In rural Punjab in Pakistan, farmers and villagers gather in places called ‘deras’ to socialise, drink tea and coffee and discuss their farms. But one project has created a community network to transform one of these deras to have digital facilities – a ‘digital dera’. Farmers use this digital dera to access crucial weather forecasts and other information to help them manage their farms more efficiently. It also helps them battle the impact of climate change, as the crop cycles change due to shifting weather patterns. Founders of the project Fouad Bajwa and Aamer Hayat speak to Gareth about the impact of the digital dera project on the farming community. Offline internet in Cuba
Cuba is one of the least digitally connected countries in the Western hemisphere. This is due to the US trade embargo but also poor internet infrastructure and a tight control of its own government on flow of information. Although accessing digital technologies is getting better, for ordinary Cubans going online is still a challenge. The internet connection is slow, unreliable and prohibitively expensive. To combat this, they have created an offline underground internet called ‘El Paquete Semanal’ or ‘Weekly Package’ – it is a one terabyte collection of eclectic material of movies, tv series, sport and music, while turning a blind eye to copyright. Reporter Snezana Curcic visited to learn more about this Cuban alternative to broadband internet. Presenter: Gareth Mitchell

Data-driven football
Data-Driven football
With the end of this year’s Premier League season and the Champion’s League final in the last two weekends, viewers around the world were cheering on their favourite teams. While the rules of football may not have changed much in recent years, there is one thing that has: the amount of data. Coaches and teams can now examine player performance and statistics in great detail. Has this transformed the way the game is played? Gareth chats to Ruben Saavedra, CEO of Metrica Sports, which uses software to analyse videos of football games, and we hear from John Muller, a sports journalist at The Athletic, and Jordi Mompart, Director of Research and Analytics at FC Barcelona. The tech behind the ABBAtars

Reclaiming African art in digital form
A Nigerian project called Looty is seeking to take back African art in digital form. Members go into museums, take LiDAR scans using their phones, and recreate these African artworks as non-fungible tokens (NFTs). The first piece is one of the Benin Bronzes from the British Museum. Different artistic reimaginations of this ancient artwork are now being sold as NFTs, with parts of the proceeds going to emerging Nigerian artists. Gareth speaks to Looty’s founder Chidi about the idea, and blockchain expert Anne Kaluvu comments on the project. The innovative vision of Amazonia 4.0
The Amazon rainforest is being destroyed at an alarming rate. Could there be another way? The project Amazonia 4.0 is envisioning harnessing the rainforest’s inherent biodiversity through a sustainable bioeconomy. Professor Carlos Nobre explains how, with the help of drones, fibre optic cables and other technologies, this vision may become a reality. The common fruit fly’s digital twin
One of the most ubiquitously used and best understood organisms in science is the common fruit fly. Many important developments in medicine and biology stem from research on this tiny insect. Now Professor Pavan Ramdya and his team have developed a complete simulated model of the fruit fly, a so-called digital twin. This model can be used by researchers to conduct experiments digitally, which may help speed up research and solve unanswered questions. The programme is presented by Gareth Mitchell with expert commentary from Angelica Mari.Studio Manager: Duncan Hannant

North Korean digital control
North Korea is known as one of the most isolated countries in the world. Yet, there are North Koreans who have access to some of the same kind of technologies that are available to the rest of the world, albeit with severe restrictions. A new report suggests that some even hack their smartphones to get around the stringent digital controls. The authors of the report looked at North Korean phones and spoke to two escapees, a former computer programmer for the North Korean government and a former computer science student. One of the authors Martyn Williams as well as North Korea expert and co-host of the BBC podcast The Lazarus Heist Jean H. Lee join us on the programme.Clean Drinking water at the push of a button
Researchers at MIT have created a portable device that can clean and desalinate seawater. It works by creating an electrical field that pulls salt and suspended solids out of the water. Unlike other methods, this requires little electricity and no filters. Research scientist Junghyo Yoon is hoping to improve and commercialise the technology in the next couple of years.Military virtual and augmented reality
Microsoft has recently been contracted to construct more than 120,000 augmented reality headsets for the U.S. Army. How is virtual and augmented reality used in the military? Will it be used on the battlefield?

Can we predict Twitter’s future?
What’s in store for twitter, now that Elon Musk’s offer has been accepted by the Twitter board? Bill and Gareth discuss.Is video chat tech still listening when you’re muted?
Video conferencing technology might still be listening to your voice even when you are on mute. A new study shows that a number of video meeting apps were recording audio even when the user had switched off their microphone. The researchers analysed the code behind the apps and found that all of the apps in the test were gathering raw audio when they were on mute – and that one of them was sending that information over the internet at the same rate, whether the user was muted or not. They even identified what someone was doing 82% of the time e.g cooking, typing. Professor Kassem Fawaz, one of the authors of the study, explains more.World first – swarming molecular robots working together
Scientists from Hokkaido University in Japan have for the first time shown that molecular robots are five times more effective at transporting cargo when working as a swarm compared to working alone. Inspired by insects, like ants, honey bees and even fish and birds, they have created microscopic molecular robots that use microtubules propelled by proteins and DNA. Dr Mousumi Akter explains how they work together so successfully and the possible applications which include intensive drug delivery to a specific location or collection of micro-contaminants in the environment.How to encourage more women into game design
Many women enjoy playing video games – but why are so few of them involved in designing them? Our gaming correspondent Leigh Milner has been meeting those at the top of the business, who are doing something to widen access to its creative side.The programme is presented by Gareth Mitchell with expert commentary from Bill Thompson.Studio Manager: Giles Aspen
