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.
