Could 3D-printing be serving us up a tasty food revolution, or is it the ultimate in gimmicky processed foods taking us yet further away from natural eating? In the kitchen, a 3D-printer builds up customised tasty treats like exotic cheesecakes, layer by layer, using edible pastes, gels and liquids. The results look delicious, and delicate, and can be tweaked to suit the individual’s specific nutritional needs. The latest possibilities are one of the main courses in the latest issue of npj Science of Food. One of the article’s authors is Dr Jonathan Blutinger worked at the Creative Machines Lab at Columbia University in New York where the research was carried out.
Jimmy Wales on AI and its impact on Wikipedia
In our second interview with Wikipedia Founder Jimmy Wales, Gareth asks about the balkanisation of the internet and how ChatGPT and other AI tech could impact Wikipedia.
Bollywood and the multiverse
India is now officially the most populated country in the world and everything there is measured in huge numbers. Take film, for example. With nearly two thousand films made each year in over 20 regional languages, India produces the most films worldwide. And Bollywood is just a part of it. This year marks 110 years since the first Indian feature movie was made - ‘Raja Harishchandra’, a silent movie by legendary Dadasaheb Phalke. Since then Indian film has come a long way, winning an Oscar in two categories at the Academy Awards this year. Our reporter Snezana Curcic recently went to Mumbai, the city where it all started. She’s explored how digitalisation has disrupted and affected the industry and Indian film audiences in recent years.

Computer labs for schoolchildren in rural Kenya
Nelly Cheboi’s nonprofit, TechLit Africa, has provided thousands of students across rural Kenya with access to donated, upcycled computers - and the chance for a brighter future. When she began working in the software industry, she realised that there are many computers that are thrown away as companies upgrade their technology infrastructure. So, together with a fellow software engineer they founded TechLit Africa. The students not only get upcycled computers but are also learning various skills such as coding. Wairimu Gitahi reports from Nairobi.

It may seem that in some countries surveillance cameras are everywhere – recording almost our every move. We are using fingerprints and facial recognition to get access to our banking, work emails and even our healthcare systems. Alongside this rise in use comes a rapid increase in biometric data gathering, spurred on by contact tracing apps during COVID19. But where is this very personal data going, who is using it and how.
We bring together a panel of experts to discuss what’s happening now and what’s next for our biometric data – shouldn’t we be the ones in control of our own digital identity? Dr Stephanie Hare, author of Technology is Not Neutral: A Short Guide to Technology Ethics, Alice Thwaite, founder of the Hattusia consultancy and The Echo Chamber Club a philosophical research institute, and BBC China Editor Howard Zhang are all on the show.

As Ukraine enters the second year of the full-scale Russian invasion, we hear about an app through which citizens can help alert defence authorities of air attacks. To help prevent future attacks, the country’s Air Defence Forces want people to use their phones to report hostile airborne objects. Simply install an app, point your handset at the object, select the category – say a drone or a missile - and press the button. It means observers on the ground can pick up objects flying too low for radar detection. Gareth speaks to one of the app’s developers, Gennadiy Suldin of the tech start up NGO Technari.
Supercomputing predicting weather in Brazil – has it worked?
The clear up continues in Sao Paulo following last week’s devastating floods and landslides, which have claimed dozens of lives. But could these extreme weather events have been better predicted with supercomputers? Angelica Mari has been asking if Brazil’s supercomputers are super enough?
Spotting illegal farms in Taiwan with citizen tech
With 1500 hectares of farmland lost to illegal usage each year in Taiwan, an environmental advocacy group tried to find ways of bringing this attention to the wider public. Stuck for what to do and not wanting to use conventional means like petitions, they turned to Taiwan’s volunteer technology community for inspiration. Shiroma Silva went to find out more for Digital Planet.

After the devastating earthquake in Turkey and Northern Syria, how do you collate data to aid those coordinating the disaster response? Cecilia Utas from DEEP (Data Entry and Exploration Platform) explains how important data is in disaster relief and crisis management. And Aziz Şasa from the Turkish Amateur Radio Association also explains the vital role of amateur radio as a key communication method in the region after the earthquake.
High altitude communication platforms
After multiple objects have been shot down in US airspace, Professor David Grace from the University of York is on the show to talk Gareth through these high-altitude communication and surveillance platforms. The devices serve many purposes and take many different forms, from balloons to airships.
Electricity from human waste
In the village of Lelo in South Western Kenya, 21 year old Vincent Odero is harnessing electricity from a surprising source – human waste. Using some wires and wooden poles, he is making enough electricity to power his home. Wairimu Gitahi went to meet Vincent and to see his invention in action.

Within hours of the magnitude 7.8 earthquake across Turkey and northern Syria, the internet in Turkey was partially shutdown. And it wasn’t just because of damage to network infrastructure from the quake itself, but Twitter was blocked, as the authorities raised concerns over misinformation online.
Internet shutdowns are used by governments around the world to control people’s access to information, for example during protests, but also somewhat surprisingly to prevent cheating during public examinations.
Shutting down the internet costs individuals and countries huge amounts of money. The TopTenVPN annual report which analysed every major intentional internet shutdown in 2022 has revealed that they cost a world economy, already reeling from a number of shocks, a further $24 billion.

What is happening with API’s, more commonly known as bots, on Twitter? The platform is set to eliminate free access to its APIs this Thursday, although there appears to have been some backtracking following announcements that bots providing “good content” will have access to the Twitter API for free. Tech writer, broadcaster and bot user and creator Kate Bevan will be on the show with the latest.
The right to disconnect
Kenya is the latest country to propose a new law that will block employers from interrupting their staff during their time off. The Employment Amendment Bill aims to give Kenyans “the right to disconnect in the digital age” and protect them from working out of hours, at weekends and public holidays – often for no additional pay. Nairobi based tech reporter Wairimu Gitahi is on the show.
Tech that tells you when fruit is ripe
Harvesting a crop at the correct time is vital to ensure higher profits for the farmer and also to reduce food waste. Reporter Rani Singh has met two entrepreneurs in India who have developed a device that checks 19 vegetable and fruits for ripeness, texture and taste – just by scanning their skin. The handheld device checks the chemical composition e.g. sugar levels of fruits and veg and can tell if there has been damage from insects or disease.

One of the main causes of maternal mortality during childbirth is that the baby cannot be delivered vaginally, most likely because it isn’t positioned correctly in the womb. Without a plethora of medical equipment and training to check the baby’s position, midwives and doctors in developing countries struggle to reposition the baby safely. Scientists at UCL have developed a smart glove that links to an app, which in lab tests appears to be able to correctly identify the position of a baby’s head and how much pressure is being applied to it. The glove costs a $1 making it an affordable solution in developing countries. Dr Shireen Jaufuraully and Carmen Salvadores Fernandez of University College London, lead authors on the study, explain their work so far.
Photometric-stereo 3D imaging reveals secrets of the past
At the Bodleian Library in Oxford in England, a series of previously little studied copper plates is now, finally, giving up its secrets after three hundred years. The shallow engravings on the copper have become worn and difficult to read after more than three centuries. So, researchers are picking out relief on the metals surface by moving a light around, to draw out the shadows and give contrast. Except, this is a moveable virtual lamp, thanks to some clever 3D imaging. Hannah Fisher has been to the library to find out more about the ARCHiOx project.
WiFi seeing through walls
Scientists at Carnegie Mellon University are able to detect the 3D shape and movements of human bodies in a room, using only WiFi routers. The WiFi method overcomes problems with cameras e.g. poor light. The tech could be used to monitor elderly people at home or check on intruders. Professor Fernando De La Torre Frade and Dr Dong Huang from Carnegie Mellon University tell Gareth more.

In the summer of 2021 Kazakhstan was the second biggest producer of Bitcoin in the world, but what has happened since the crypto currency crash? Tech reporter Peter Guest is on the show to tell us about his trip to the country and how mega warehouses that once contained the computing power to make crypto millions now stand empty in the country’s rust belt. He tells us the story of the rise and fall of the bitcoin miners in this remote part of the world.
Wearable tech, AI and potential new treatments for rare diseases
Duchenne muscular dystrophy (DMD) and Friedreich's ataxia (FA) are very rare genetic diseases neither of which has a cure. Now scientists and engineers in the UK have used motion sensors to capture the way patients move. They processed this data through new AI medical technology that they say can predict disease progression and significantly increase the efficiency of clinical trials in these conditions. Treatments are desperately needed as both diseases can lead to paralysis and currently there are often not enough patients for clinical trials. Dr. Valeria Ricotti, honorary clinical lecturer at the UCL GOS ICH and lead author of the studies is on the show to tell us more.
Sony’s new game controller for disabled gamers
Our gaming correspondent Chris Berrow reports on Sony’s new “Project Leonardo”, its PlayStation 5 controller for disabled gamers. The company teamed up with accessibility experts and charities to design the modular controller which can be adapted in many different ways to allow as many people as possible to use it. Launched at CES it still doesn’t have a release date or price though.

MIT researchers have concluded in a new study that computers that power self-driving cars could generate as many greenhouse gas emissions as the total of the world’s data centres do today. We’ve reported many times on the huge carbon footprint of data centres as well as the massive amounts of electricity needed to run them. They currently account for 0.3% of global greenhouse gas emissions – a similar level to Argentina - according to the International Energy Agency. The models created show that 1 billion autonomous vehicles, driving for one hour a day each, need a computer consuming 840 watts. These would consume enough energy to generate similar emissions as data centres currently do. Lead author Soumya Sudhakar joins us on the show to explain how hardware efficiency will need to advance rapidly to avoid these high levels of emissions.
Brazil’s antisocial media
Following last week’s events in Brasilia we look at the role social media played in the violence by far-right protestors. Angelica Mari, and activist and researcher Bruna Martins dos Santos who specialises in the Politics of Digitalization discuss if President Lula’s new government can reclaim the social media space and curb the spread of far right disinformation.
Getting South Africa connected – a new initiative
Last week we heard from one of our listeners about how he tries to stay online during power shortages in Ukraine following Russian air strikes. Another country that is significantly affected by energy shortages is South Africa. In addition, getting a reliable internet connection is also very hard. The government has announced that it’s going to spend over 160 million dollars over the next three years creating 33,000 community Wi-Fi hotspots as well as investing in improving IT skills across the population. Our reporter Rani Singh has been looking at how this might be achieved…

AI avatars undressed and virtual employees
Ghislaine Boddington looks at the alarming story of how a young female reporter created avatars in the AI avatar app Lensa and was shocked to find that out of 100 avatars, 16 were topless and another 14 wore very skimpy clothing and were in provocative poses. Why has this app created astronauts and warrior avatars for her male colleagues and is undressing her avatars? Ghislaine also looks at the rising employment of virtual staff. The tech company Baidu says the number of virtual people projects its working on has doubled in the last year with prices of a virtual employee starting at just under $3k. Why are they becoming popular and what jobs are they being used for? Evelyn Cheng, Senior Correspondent from cnbc.com in Beijing, has been investigating the story.
An AI age verification system
Age verification has long been a topic of discussion, particularly in the online space with regards to young people who often don’t have verifiable ID such as a driver’s licence. Now a promising AI powered age estimation system, called YOTI, which analyses a person’s face is gaining popularity. Shiroma Silva has been testing it out on her colleagues – including Gareth – and reports how some major platforms are using it to keep younger users safe online.

This week and to start the New Year we take a look at the use of technology in agriculture around the world. Agriculture as an industry is keen to clean up its act on emissions, so what could be better than an electric tractor. But will it be able to manage all that farming throws at it? Gareth puts the questions to Praveen Penmetsa who is co-founder and CEO of Monarch Tractors which recently launched a ‘Smart Tractor’.
It’s no use having a tractor smart or not, if your crop has been devastated by insects. Pests destroy up to 40 percent of global crops and cost 220 billion US dollars of losses worldwide annually, according to The Food and Agriculture Organization of the United Nations, the FAO. Matej Stefancic the Chief Executive Officer of Trapview a Slovenian company, has developed intelligent insect traps. He explains to Gareth how they monitor bugs in the field, in an effort to cut the need for indiscriminate use of insecticides.
And once you’ve grown your crop you need to harvest it, and in the case of soft fruit it needs careful picking and packing for the market. With a shortage of skilled labour around the world a robot picker capable of matching a human would be ideal. Well, one developed in Britain is currently doing just that on a farm in Portugal, and fruit picked by it could be on sale in supermarkets very soon. The academic founder and Chief Science Officer of Fieldwork Robotics Martin Stoelen is the brains behind this robot and he explains to Gareth the challenges involved in developing it.

We’re looking back on the technology year that was 2022. We go firstly to Ukraine to look at the booming tech industry before the war and discuss how that is doing now. Also how the cybersecurity declaration signed in Africa is already leading to the beginnings of a legal and regulatory framework across the continent. There was trouble for visually impaired patients using an implant to improve their sight – with some of the hardware becoming obsolete and finally the amazing popularity of flight tracking apps.

More than 8 million unregistered SIM cards have been blocked in Ghana. The Ministry of Communications and Digitisation set a final deadline for mobile phone users to link their SIM card to their identification cards and now those who haven’t been able to register can’t use their SIMS. Opposition parties and civil liberties groups are protesting as the SIM needs to be registered with the biometric Ghana Card. The scheme has been full of delays, but it looks as though the government is standing firm this time. BBC Reporter in Accra Thomas Naadi is on the show.
Heart attack on a chip
Researchers at the University of Southern California have developed a “heart attack on a chip” to ultimately test new drugs and even personalise medicines. Professor Megan McCain and Dr. Megan Rexius-Hall speak to Gareth about how the chip can monitor oxygen imbalances that happen in the heart during an attack. The heart muscle doesn’t regenerate as well as other tissue in the body, meaning patients are often tired and don’t recover to the previous levels of fitness. The chip will allow researchers to watch a ‘heart attack’ as it happens – which isn’t possible in animals – and see how damage is being done. They hope to be able to monitor and see how the cells on the chip respond to different concentrations of oxygen as this too can’t be studied in animals or humans.
The end of hard copy games?
Nowadays, video games are getting so big, that you can't even fit them onto a CD anymore! In fact physical copies of the latest Call of Duty Game - Modern Warfare II, were essentially links to download the game, which is a massive 130 gigabytes! Our gaming reporter Chris Berrow has been finding out if it really is the end of physical games.

One of the biggest platforms in Southeast Asia – which is as popular as Google, YouTube and Facebook – has stopped bank transfer payments. Users have reported money missing from their accounts – the transactions should have been secured with a one-time passcode but according to social media they we processed without permission. Shopee have now stopped customers from linking their accounts to the platform directly. The company also denies they were hacked and that they had taken the decision to stop bank transfers last month. It also says that the customers were probably victims of phishing scams. The BBC’s Tossapol Chaisamritpol has been covering the story and joins us from the Bangkok Bureau.
Facial recognition plans dropped in Sao Paulo – for now
Plans for the controversial facial recognition surveillance system in Sao Paulo have been scrapped – at least for now. Twenty thousand cameras, half of which had facial recognition capabilities, were to be erected across the city – making it one of the largest facial recognition rollouts in the world. Much opposition from civil liberty groups – who claim that the system would allow the city authorities to track people’s activities on social media with the data they gathered through the cameras – has forced this announcement. However, many people fear this may just be a postponement. Angelica Mari explains more.
3D printed violins
Imagine printing a violin in library for just $7US? That’s what Dr. Mary-Elizabeth Brown, the Director of Montreal-based AVIVA Young Artists Program, has managed to do. The instrument at this cost is suitable for a young child to play, and full size instruments can be 3D printed but with industrial printers, not ones we have at home or in local libraries. Dr. Brown is on the show to explain the technology behind the printing and why she is determined to make learning musical instruments much more accessible.

Due to climate change cyclones are increasing in frequency and intensity. Data available to study these weather phenomena though is quite scare, so a new project at Imperial College in London, hopes to harness the computing power of people’s mobile phones to create a virtual supercomputer and create a massive public database of simulated cyclone models to help predict future events. Professor Ralf Toumi, Co-Director of Grantham Institute, is leading the project and is on the show. Listeners are being invited to take part by downloading the Dreamlab app to help process the billions of calculations needed for the project.
What is the Fediverse?
If you’re on twitter then you’ve probably heard of Mastodon, you may even have moved onto it. It’s the largest service on what is known as the Fediverse. We speak with Cindy Cohn, the Executive Director of the Electronic Freedom Foundation to find out what the Fediverse is and why we should be part of its growth. It’s not a single social media platform like Twitter or Facebook. It’s an growing network of entwinned social media sites and services that you can interact with even if you don’t have an account for each one. The big difference here is that the Fediverse isn’t owned by big tech giants or multibillionaires – Cindy Cohn argues “You don’t fix a dictatorship by getting a better dictator. You have to get rid of the dictator. This moment offers the promise of moving to a better and more democratic social media landscape.”
An app that helps you buy medicines if you’re blind
The tiny print on medicine packet instructions is hard to read for many people, and for those people with low literacy skills, learning disabilities like dyslexia, impaired sight or who are blind it can be impossible. Now the Seeing AI app – a joint project between Haleon and Microsoft- has been upgraded to be able to read out loud the detailed information on more than 1500 products across the UK and US. Our reporter Fern Lulham has been testing out the new functionality of the app.

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.

This week you can listen again to our electric vehicle Jersey road trip. Gareth and Bill are on the small English speaking island off the coast of France investigating the tech scene. We’re travelling around in an on-demand electric vehicle – all booked, paid for and locked and unlocked with an app from our smart phones. We’re finding out about agricultural tech on a dairy farm – how the famous Jersey Cows that produce premium milk are being managed by the latest innovations, and we’re also out in the fields where a host of sensors and data analytics are helping with the Jersey potato harvest. And we visit the remote control tower at St. Helier airport and see how remote airfields around the world are beginning to embrace this technology, pioneered on Jersey, to make flying to seldom used airports safer.
Guests include: Gavin Breeze, Director of Evie, Air traffic controllers Marc Hill and Richard Mayne, Jersey Cow Girl Becky Houzé and Mike Renouard Business Unit Director at the Jersey Royal Company.

Could audio files be the new digital drugs? New research shows that binaural beats - illusionary tones created by the brain when the brain hears two different tones in each ear – can change someone’s emotional state. The work, published in Drug and Alcohol Review, shows for the first time that people use binaural beats to relax, fall asleep and even to try to get a psychedelic drug high. BBC’s R&D Audio team have created a binaural beat soundscape especially for Digital Planet and we speak to Dr Alexia Maddox, a tech sociologist, one of the researchers behind the study.
Publishing via What’s App – getting female authors recognised in Zimbabwe Getting a book deal may seem like an impossible dream for many budding authors, but in Zimbabwe, for many female writers, this is a reality. Linda Mujuru, a senior reporter for Global Press Journal, tells us how most publishers are struggling in Zimbabwe due to the dire economic situation over the last twenty years and why so many authors have turned to social media as their only way of telling their stories. Samantha Rumbidzai Vazhure set up her own publishing house in the UK as she could not get her work printed. She reads one of her poems in Shona, a native Zimbabwean language, and explains how she now looks for fellow female authors online and publishes their work too.

Télécoms Sans Frontières has sent satellite kits to Tonga to improve connectivity on the islands following the volcanic eruption. Before the pandemic TSF would have immediately deployed to Tonga after it went dark, but strict quarantine rules limit what they can do. As their engineers can’t go out, they’ve had to adapt the equipment they send so that it can be set up on the island. Their kit is now out of quarantine and should be deployed imminently and will eventually bring internet connectivity to the smaller islands where people are still completely cut off. TSF Regional Manager Sebastien Latouille also tells us in the podcast about their latest deployment to Madagascar following Cyclone Batsirai.
Could NFT protect our health data? If you think NFT’s (non-fungible tokens) are just the new way to buy art then think again as they could be the way to secure our medical data. Once our medical information is digitised into an electronic health record we have no control over what is done with it. Writing in the journal Science, Prof Kristin Konstick-Quenet, suggests that NFTs could provide a way to secure ownership over the management of digital information using blockchain technology. However, will the companies who currently monetise our medical records be willing to give up access to it? Legislation will be necessary if we are to have any control over our own health data.
Enhanced Audio Description Reporter Fern Lulham begins her first in a series of reports into the latest disability tech looking at audio descriptions of films and TV shows. There's plenty of evidence to show that despite the draw of social media and endless other activities, watching telly or going to the cinema remain extremely popular. In the UK for example, figures tell us that even before the pandemic, people spent an average of just over three hours a day watching TV, And since the mid -80s, visits to the cinema had risen quite dramatically to well over 150 million a year before Covid19 restrictions kicked in. But how accessible are these media if you're blind or visually impaired?

The first-ever robotic surgery without a human surgeon guiding it has been successfully performed at Johns Hopkins University. The Smart Tissues Autonomous Robot (STAR) completed a keyhole procedure called intestinal anastomosis – the sewing together of two sections of soft bowel - on pigs. More than a million of these surgeries are performed each year in the US alone and they need to be carried out very precisely and accurately to avoid potentially fatal complications. Professor Axel Krieger, the mechanical engineer on the team, tells Gareth how this is a major advancement in robotic surgery.
Singapore Surveillance Singapore often introduces innovative tech to its citizens, but there is a lack of transparency about the way the data is collected and used. As public tech becomes more affordable it is becoming increasingly available. While the hope is it will solve complex social problems there is no transparency over the algorithms used. This means we don’t know the kind of prejudices, privileges, and assumptions being built in. Without intervention, societal prejudices will continue to be perpetuated. Peter Guest from the Rest of World website has been looking into the dangers of public tech in Singapore and beyond. He tells us why tech companies need to be more transparent.
unReal City Backstage at the Brighton Dome looks more like the technical suite of a TV studio than a theatre, as technicians watch multiple screens showing the audience and actors in different rooms - and showing a variety of feeds from their VR headsets - because this piece of immersive theatre, unReal City, takes place in both physical and virtual reality. Reporter Claire Jordan has been meeting with the Director and disabled artists from Access All Areas - a learning-disabled theatre company - behind the production, which explores if it’s easier or better to connect in the flesh or as an avatar and if links are stronger in reality or could the Metaverse allow us to re-invent ourselves.
The programme is presented by Gareth Mitchell with expert commentary from Bill Thompson.

Connectivity to Tonga partially restored but undersea cable repair could take weeks. The underwater volcanic eruption severed the country’s only underwater network cable and ash clouds have made satellite connectivity impossible. Professor Nicole Starosielski from NYU, an expert in underwater connectivity and author of “The undersea network”, joins us on the show. An underwater cable is severed every three days somewhere in the world, yet the network has the capacity to usually cope with this disruption. Many developing countries do not have this extra capacity as they cannot afford it. Professor Starosielski argues that richer nations should step up and fund this lack of spare connectivity.
Virtual IT brain drain in Argentina IT workers in Argentina are being enticed by US and European tech companies to work remotely for them, by offering very attractive salaries and remote working contracts. Local IT businesses are struggling to retain workers as they leave for salaries in US$ or Euros that can be four times what they are currently earning. And this is what is different about this type of employment, unlike outsourced IT workers in India or Africa, the employees are not working on local conditions. As reporter Lucila Pelletieri from Global Press Journal tells Gareth, the loss of local talent will impact not only the country’s IT companies but potentially the economy as well.
Robot training made easy We hear about machine learning all the time, but how does a machine actually learn? Say it’s a robot that you need to teach to perform a task in a factory, or even in your home. Well, it’s ok if you happen to be an ace programmer and are happy to dash off a load of computer code. But at the Robot Learning Lab at Imperial College London, they want to make it easier for us to train the machines - as easy as grabbing the robot’s arm and moving it through the task, so that next time, the bot does the movement itself. The Lab presented its latest work at a robot learning conference just before Christmas. The lab’s director is Dr. Edward Johns and Gareth has been to pay him – and his robot – a visit.

After 222 days the social media platform is back up and running in Nigeria. The country suspended Twitter after it deleted a tweet by President Buhari and Nigerians have been accessing the platform via VPN, but now Twitter has agreed to the government's demands which include opening a local office, paying taxes, and being respectful of Nigerian laws. Abubakar Idris, the reporter for tech site Rest of World, joins us on the show. We are waiting on a response from Twitter.
100 years of the BBC The BBC Historian Robert Seatter joins us live to talk about some of the tech innovations that the BBC developed over the last 100 years. He’s behind these amazing websites - Objects of the BBC - BBC 100 www.bbc.co.uk/100 and even more will be revealed throughout the year. He will be discussing the first OB in 1924 (The Cello and the Nightingale), the development of the first ribbon microphone by BBC engineers (as the BBC could not afford those designed in Hollywood), the fully digitised audio archive, and many other marvels of tech innovation.
Ban on online education classes in China A few months ago, we reported on the Chinese government’s ban on online video gaming in children, where it restricted it to three hours a week. That was followed by a new set of regulations on private tutoring that has hit some of the biggest tech companies in China. While the new rules will certainly give young people more leisure, there’s a lot more to it than children’s well-being. On the show today we have science and technology journalist Yuan Ren to explain one of the biggest shakeups in Chinese education.
