    3D printed food – what’s cooking?

    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. Pod EXTRA: A make-up applying app for the visually impaired How would you feel about applying make-up for a date or an important meeting without the aid of a mirror? Well, if you're blind or visually impaired, that's effectively a situation you might find yourself in on a regular basis. But now it seems help could be at hand. A new app called the Voice Enabled Makeup Assistant has been developed by the International cosmetics company Estee Lauder. So will it help if you're a blind dater, or is it all just lip service. Our reporter, Fern Lulham takes up the story. The programme is presented by Gareth Mitchell with expert commentary from Ghislaine Boddington.

She’s on the show to explain how this will change the way we communicate and tells Gareth that we should be connected to 6G by 2030. 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.

    Ukraine’s drone spotting app

    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. The programme is presented by Gareth Mitchell with expert commentary from Angelica Mari.
