this is bbc news. the headlines — donald trump becomes the first former us president to face criminal charges. the charges are thought to relate to falsifying business records to hide hush money payments to a porn star. the social media personality andrew tate is to be released from prison after winning an appeal. he will remain under house arrest ahead of further hearings. italy becomes the first western country to block the ai chatbot chatgpt over privacy concerns.

oscar pistorius, the former paralympic sprinterjailed for murdering his girlfriend, has been denied an early release from a prison in south africa. the parole board said he hadn't completed his minimum detention period. at 10pm, reeta chakrabarti will be here with a full round—up of the day's news. first, click. plenty on the menu this week. yeah, paul's with the robots that help blind people to pack and stack. and ai helps jamie oliver

cook up some spanish. spanish dubbing. meanwhile, would you let lara cook you dinner? oh, the stench! that is absolutely overwhelming! it's leftovers again. i think i'll go for takeout. it seems that the whole world has been talking about artificial intelligence recently. it's "chatgpt" this and "ai art" that. you can have conversations with it, you can be creative with it and the recent release of gpt—ll seems to be displaying levels of understanding of questions and images that are astounding the experts. this is the uk's national centre for data science and artificial intelligence, the alan turing institute, named after the mathematician considered to be the father of computer science. artificial intelligence is the idea of notjust us

programming computers, but them being able to learn for themselves and alter their own code. yeah. and, in fact, it was the big guy himself who came up with the idea of the turing test, suggesting a computer could be regarded as truly intelligent if it could chat to a human and fool that human into thinking they were talking to another human. now, you and i have both tried chatgpt and all the latest ai chatbots. do you think that test has been passed now? to some extent, yes. i do think they can seem human, but there are some caveats to that. yeah, i think you're right, but i do think that they are convincing enough these days. the problem is that version of the test turned out to be too easy to solve and not really a sign of human—level intelligence after all. and, of course, it's important to remember that al isn'tjust about chat, it's about bringing in loads of data and learning from that. and it can be used to solve all sorts of problems, possibly even this one. a third of all the food produced globally for human consumption is wasted.

that's about 1.3 billion tonnes a year. then when that food breaks down in landfill, it releases harmful greenhouse gases, whilst at the same time, there's a struggle to feed an ever—growing global population. so i visited one company in cambridge that thinks it can provide some help. the set—up here consists of a series of containers, which means that it can be recreated anywhere. this is the brains of the whole thing inside this cupboard. it's a lot of leads, so many leads. and through these pipes comes the food waste. in there is a mix of old vegetables, old fruit, bakery goods. it comes down into this big container, where it's all blended and effectively turned into a big soup. it checks that the temperature's right and the ph is balanced and then it comes out through this pipe and goes through into the next room, ready for the insects.

yep, food for the insects — black soldierfly larvae, to be specific. oh, the stench! that is absolutely overwhelming! but it's not surprising, because in here, you've got the fodder and the creatures consuming it. look at that. look at how they're squirming around. i've been allowed to give them lunch. and wherever these containers are set up, sensors, tracking and an a! system goes, too. the role of ai is that we've built a platform that we can remotely operate every system we have, so that let's say that we're here in cambridge and one of our systems is out in wales. we can, from our centre here, know exactly what is going on and we can also optimise for yields, fit conversion ratios and generally the growth of the insects. the ai's monitoring the temperature, atmosphere, their growth rate and what the larvae eat.

once they're perfectly fattened up, they move on to the next stage of the process. the larvae and that food they've been consuming all comes down these pipes. it'll then be separated in this device. then it's not long before they rather quickly reach the end of their days, and, once they have, they get separated into the useful bits of fat and protein before they get packaged up, ready to be used in products. right now, the insects are being used as animalfeed, a replacement for soya bean. the insect alternative is nutritious and has a much lower carbon footprint. so, when we started to commercialise the technology, we decided to focus on one specific sector, and that was the poultry sector. so we converted food waste from the supply chain into carbon—negative animal feed. that was larvae that got fed to chickens, and they produced carbon—neutral eggs. and the next step is to move the product up the food chain.

so here we've got some feed for dogs, both dry and wet, and something for humans. and i happen to know that suhail, my cameraman, here, loves a bit of cake, don't you? you can't say i never give you anything. these are madeleines. they're 30% protein. mm. take a bite. how is it? mm. they're really good. i would've never guessed there's insects in this. i so it tastes like cake, moist in the middle? it's very moist. it's a great texture. definitely couldn't tell it's made of insects, 100%. l there's your lunch. they laugh. i might have a second one, actually! they're quite good. well, suhail seemed happy, but he's always very easy—going. how ready is everyone else? insects are very nutritious. they're very sustainable to produce. you require 99% less land, 99% less water. and, of course, the emissions is significantly lower and also, they taste great. so if you have those

three pillars ready, the foundation is there. but i think it's a matter of marketing and people getting more familiar with it before we introduce it to the wider public. insects are widely eaten in many parts of the world, but whether everyone can switch their mind—sets to expecting them for dinner is another question. bellissimo! perfect. hm, that seemed rather pungent. suhail seemed to enjoy it, though, didn't he? did he take a doggy bag home, ora...larvae bag? he actually told me that the cakes were a bit dry afterwards, but he did kind of enjoy them. if you don't fancy insects for dinner, though, alasdair keane has been finding out how jamie oliver's team has been using al to help show the world what's on the menu. millions of hours of video content is watched online each week with platforms full of everything from the bizarre... ..to cooking. the internet loves carbonara. pasta, cream, bacon...

cream? it's fact. and there are the wrong ways and the right ways to do it. a classic italian dish. what's not to love, right? but it's really controversial. so much of that content is in english, costing too much time and money for companies to translate and revoice with actors. now the jamie oliver team are turning to ai and a company called papercup to take the chef to new audiences. it's about the numbers game in this world, so the more content you can put out, the more people can engage with it, the more they might... vegetarian, they might only like pasta recipes, they might not. so there's lots of different sort of subsections in our content, so being able to do the volume is really useful for us. and this is where everything happens. this one's about chocolate brownies, and it says chocolate all the way through it. the programme not only translates the video automatically, but also overlays a dubbed computer—generated voice in the new language. a team of translators then quality—check it and adjust the voice to make it

sound more natural. we pay attention to l detail when it comes to the characters we're dubbing. spanish dubbing. we use all the tools we have in hand to make it sound - as accurate as possible. in this case, i chose number ten cos it's the most suitable one _ forjamie oliver in this case. and then here, you can play with speed. - you can play with the mood. actually, i need it to sound i a little bit more expressive, so i'm going to change it to happy. more spanish dubbing. all of these subtle changes in the style of delivery to the odd word or sentence are combined to make one coherent voice, improving the watch experience for the viewer. german dubbing. synthetic voices maybe are quite usable when it comes to home assistants and article—readers and chatbots, and i think that's where you see a quite a big application.

but we've spent literally five years trying to craft voices that are specifically suited for video. now what we're producing is literally indistinguishable from human speech. dubbing in different languages. how long does it take to go through a video? well, that's hard to say. it really depends on the video we're working on. _ but so much faster than traditional? oh, yeah, definitely. you represent a huge brand injamie oliver. it must be hard to trust the ai. you know, sometimes it might not be fully accurate or it might not be... the intonation might not be as good as it could be. but this is better than not having the solution. the positives that come out of it far outweigh any negatives that you might have about that. this tech is also being applied to more complex videos like tv talent shows. dubbed speech. but with creating something

so human—sounding, is there a danger that this tech, in the wrong hands, could be used to trick people or provide harmful information? onus is on companies like us. it's ourjob to help also create these watermarks or these characteristics that we embed in the output that we produce that we know will almost identify the fingerprint that says this was produced by papercup. and that way we can always trace back what is something that we've produced, versus what is something we think is actually authentic and real. we're starting off with really good quality dark chocolate. _ for now, papercup is focusing on video that wouldn't normally be translated and revoiced, but perhaps in the future, similar techniques could be applied to blockbuster movies and tv shows. until next time, take care. bye, guys! next up, the final instalment of our awards season

behind—the—scenes look at visual effects. the hell kind of mission is this? this time, we're talking to the team behind the bafta and oscar—nominated top gun: maverick. bogey in the air! the role of visual effects is very much, how do we make it- so we are never noticed? and that's when we knew we did ourjob the best. i when we're putting a bunch of cg jets right along - real photographed jets, i you have a bar that is set that is so incredibly high - that there is no compromise. my standpoint as the visual effects supervisor, what i was trying to do is make sure that we were giving our team the best beginnings of that shot design. so it was a real camera operator filming a realjet in the sky. and even though in the story, we might be changing those jets to a tomcat or a su—57, which is the enemyjet or dark star, which is the hypersonic prototype aircraft at the beginning of the film, even though those jets would ultimately be what the audiences saw, i still wanted the team to be able to start

with something that was real. i worked really closely with our advisers in the navy to figure out how to sort of take what was on the script to the screen in the sense of what specific manoeuvres pilots, real pilots, would be doing in those combat situations. for us to kind of look at just . the glancing angle of the edge of an aircraft and understand, - how does the light actually interact and bounce and wrap around it? i it's aspects of cg that are oftenl considered very basic cos it goes to very early rendering techniques, i but dialling and actually getting l the precise nature of those shaders to accurately create _ what the surfaces of these jets look like is something that is very, - very uniquely challenging, - especially when you consider that most of the materials on these jets are top secret. _ you know, we really were attached to this group of men and women who do this for a living, and theyjust had so much, a wealth

of knowledge that they gave us. and i think that their contributions are a huge part of why we were able to do what we did. we're going into combat on a level no living pilot's ever seen. not even him. don't know about you but i love that film. time for tech news. finance is being regulated and has saying it is making regulations to keep users off the platform. twitter will only allow verified users to vote in polls or have their posts recommended to other users from the 15th of april. the chief executive says it's part of efforts to tackle box on the platform. we

successful games ever. king, the company behind it, is part of activision blizzard, currently the target of a takeover by microsoft. i sat down for a chat with king's president, tjodolf sommestad. what is the secret of candy crush? it's an amazing game. and we launched the game when there was a big appetite for content on mobile phones, and that's a bit more than ten years ago. so actually, last year, candy celebrated its ten—year anniversary and we continue to develop the game, add more content, add more innovation, add more excitement for the players now for more than a decade and we have more to come as well, but i think that continued innovation and, like, making the game better every week, every day, every month, our players have really responded to that. there's some criticism, isn't there, of the freemium business model where you play for free, but you pay for extra features or added experiences. what are your thoughts about that model? would you consider a subscription model instead? i think the model that we have is great for candy crush. it's a game that, like, the majority of the players are playing for free. it makes it very accessible across the world. and players can choose

if they want to, like, invest some of their money into the game to have an even richer experience. that's a model that's worked really well for us. we have complemented that with other business models. now it's possible to also watch ads in the game and get some rewards in return for that. what level are you on? i'm at 4061. and how are you finding it? it's awesome. like, it's really fun. right now, we have an all—stars tournament going on that i'm engaging deeply in. how does the mobile games market compare to the console games market? the mobile games market is nowjust as big as the console games and the pc games combined, actually a bit bigger. so it is the dominating kind of platform to play on. you're certainly in demand, aren't you? microsoft is looking to buy activision blizzard, which king is a part of, and microsoft says it wants access to the mobile gaming market, which you have. how does that feel? we are excited about the merger. i mean, microsoft has said, like you said, that they are interested in expanding more in mobile and at

king, that's where our home is. and, like, we have 233 million players in oh, monthly players in 04 in mobile. so it would be interesting to partner with them and see what we can do together. where does artificial intelligence fit with king? it's something that we looked at for years, and the acquisition of the swedish company peltarion is strengthening that with talent and experience and some of the technology that they also can bring. and they're now integrated with our team and we're looking to build, like, an ai hub, like a centre of excellence inside king. do you think a! will be creating games for us? not in the near—term, forsure, but, like, it is a very useful tool. there's a lot of lay—offs going on, aren't there, in big tech in the us? are you finding more people are knocking on the door? we're seeing a change, and of course we notice a bit of that. but my perspective is that it's not necessarily going to be much easier because we have a very high bar on, like, finding talent that has

the experience or have the energy and the drive to come in and really add value to our amazing teams. now, in the united states, disabled people are three times more likely to be out of work than non—disabled people, and you'll find similar figures in many developed countries around the world. but at one company in austin, texas, 250 of its employees — that's over half of its workforce — are either blind or visually impaired. and paul carter has been to find out about the assistive technology that they've been using. this is austin lighthouse, and it's a workplace with a difference. lighthouse is a nonprofit organisation in texas dedicated to improving the lives of blind and visually impaired people in the area.

and it's turning to technology to help them achieve that. so the box comes out, we have to glue it. and then this is the label that comes out that goes to the box. its main areas of work are in manufacturing, warehousing and distribution, primarily for the us department of defense. it has over 900,000 square feet of space and processes over 1300 orders every day. so efficiency is key. a range of tech solutions have been deployed here for a variety of purposes, from enabling people to carry out work—specific tasks to navigating the environment and more. one such solution is called vocollect, a wearable tech incorporating voice recognition. because it's auditory, blind or visually impaired people can use it to manage inventory. what it does is it allows us to go pick the orders.

you can do it as a totally blind person because it talks to you and you talk to it. it's all voice recognition. each of us have our own profiles. it's wi—fi, bluetooth, and so we have what is called orders, and there's a barcode on the order. we scan that barcode and it speaks to us where we have to go, how many we have to pick, and what the product is. we have a few other things that have really helped integrate a lot of stuff and help make morejobs for a blind or visually impaired person. also buzzing about the vast warehouse are a range of robots, part of a partnership with robotics company zebra. these help minimise the amount of navigating that disabled workers need to do among the pallets. so the robots themselves make noise and they have radar technology, lidar technology so you don't end up having an accidental interaction between an employee and a robot. and then we are also able, through the system that zebra has, to have somebody who has visual

impairment actually be able to programme the robots in the warehouse, but it is otherwise automated. so you don't have to worry about constant interaction with it. but it's important to note that segregated, siloed employment is not the target here. what's amazing about a place like this is that the technology being deployed here is being used in a really inclusive way, and that's because it's enabling disabled people to do exactly the same jobs as the non—disabled people working right alongside them. a big element of the work done by lighthouse is to help its disabled employees learn skills and progress into other, more mainstream workforces. our objective is to allow . people to be on the career path that they want and, | to do that, some of them are going to stay here. many people want to learn skills here and then movel on to something else. if you're going to move -

on to a different company, you have to have the skills _ or you have to be in the environment that would be needed to bej competitive on the outside. so we've incorporated more - technology, some of the technology that you would find out in town. some of the technology is a leveller. _ it's the technology that allows people to do. i with that technology, - we now have 20 or 30 blind people picking orders. and processing orders. this device is called the onyx. it is a closed—circuit tv that's very portable. one way they achieve this is by teaching blind people both within the organisation and outside about the range of assistive technologies that exist for people with visual impairments. the assistive technology room has a large range of screen readers, magnifiers and optical character recognition equipment for people to use. essentially, it serves as a hub for people to be exposed to or introduced to assistive technology. people who are blind typically are blind later in life, which means that they undergo a very lengthy and a lot of times arduous and difficult transition into blindness. automated voice: bbc-homepage.

ourjob is to introduce people to that technology that can help them reintegrate themselves into society, but with a focus on the workforce. so people who come here to the austin lighthouse inevitably leave with the skills they need to go back to work. technology continues to have a positive impact on the employment landscape for disabled people. while inclusive employment will always be the ultimate goal, for now, organisations like lighthouse are helping to show the way. that was paul. and that's it for this week. yeah, and from me, from lara and the big guy himself, thanks for watching. we'll see you soon. bye— bye.

hello there. after a very dry february right across the country, march has more than made up for the lack of rainfall, certainly across england. in fact, in the south—east quadrant of england, some areas have seen more than three times the march average, and the latest met office stats for march suggest that england has been the wettest since 1981. that's all about to change, though, as we lose low pressure, start to see higher pressure into the start of april. this weekend and into next week, we'll see more drier and brighter weather across the country. but in the short—term, we still have friday's low pressure system clearing off into the near continent. it left a legacy of cloud and some weather fronts, which will bring further rain throughout saturday, certainly for northern ireland, parts of south wales, south—west england. thicker cloud also affecting eastern scotland, eastern england, with some spots of rain on it, will continue to plague these areas throughout the whole day. and it'll be quite chilly as well

here with the onshore easterly breeze, and further west, although that weather front will be fizzling out with a bit of brightness, it won't be as warm as it has been of late. and as we move through saturday night, it looks like those weather fronts will tend to fizzle out. we'll see variable amounts of cloud and clear spells, and the reason for those weather fronts being squeezed out is because high pressure will be building in across the country for sunday. so a dry start for most areas, and with us importing some slightly drier air from the near continent, certainly the cloud should tend to break up. we'll see quite a bit of sunshine around. lighter winds, too. early on, we could see more of a breeze in the south—east, but those winds will fall lighter. a bit of cloud for northern scotland, northern ireland. despite the temperatures still on the low side, 9—12 degrees, when you factor in the strong early aprilsunshine, it'll feel quite pleasant. as we move out of sunday into monday, so the first working week of april, high pressure still dominates the scene for most areas. there will be variable amounts of cloud, i think, for scotland, northern ireland, closer to these weather fronts out in the atlantic,

which will make inroads for tuesday and wednesday. but, again, much of england and wales certainly will be dry, widespread sunshine. and i think temperatures will be creeping up a little bit with the abundance of sunshine. we could be close to the mid—teens. i'd say 11—13 celsius. then some subtle changes tuesday and also wednesday. high pressure starts to pull away, and we'll see low pressure and its weatherfronts pushing into northern and western areas. so scotland, northern ireland, northern and western england and wales will see some splashes of rain. a bit of cloud getting in towards the south—east, but there'll still be some sunny spells here. ourairsource, though, coming in from the south—west, so a mild direction, as temperatures range from around 12—14 celsius. wednesday, a similar story. northern and western areas plagued by some weather fronts. high pressure never too far away from the south and the east, but we will see further splashes of rain across northern and western areas on wednesday. but as the fronts push eastwards, they will be pushing into higher pressure, so they'll tend to weaken, fizzle out, to become no more than a band of cloud.

but, again, another mild day on wednesday, around the mid—teens. 111—15 degrees. and then as we go beyond, the run—up to easter, looks like high pressure wants to build back in, trying to keep these weather fronts at bay, which will scrape into the north—west at times. but this is the easter weekend. it, at the moment, looks like it could be fine and dry. the run—up to the easter weekend will also be fairly fine. perhaps a bit of rain for the north and west of the uk, but for the easter weekend itself, at the moment, it's looking pretty promising with quite a bit of sunshine. take care.

tonight at ten: donald trump sets a legal precedent — becoming the first former us president to face criminal charges. it's alleged mr trump paid hush money to a former porn star, stormy daniels, over an affair — but recorded it as a business expense. it is finally good to see some justice happened. it's a political sham and it's politically motivated. mr trump has issued numerous professions of innocence on social media — and said the indictment is "political persecution". he's due to appear in court on tuesday. also on the programme: charges of racism are upheld against five former players at yorkshire cricket club — but ex england captain michael vaughan is cleared. as the energy price cap

for businesses ends tomorrow — we talk to companies feeling the heat of rocketing energy bills.
