this is bbc news, the headlines last minute talks are taking place in switzerland about a deal to allow its biggest bank, ubs, to rescue its struggling rival — credit suisse. the deal could affect thousands ofjobs worldwide ukraine condemns president putin after he visits the devastated city of mariupol — captured during the russian invasion. an aide to president zelensky called him a criminal returning to the scene of his crime. former british prime minister borisjohnson will publish evidence in his defence ahead of a grilling by mps over whether he misled parliament about covid rule—breaking parties. mrjohnson denies misleading mps. serbia's president, aleksandar vucic, says he has

"declined" to sign a proposal by the european union intended to normalise relations with kosovo. the eu has been trying to broker a deal, fifteen years after kosovo declared independence. you're watching bbc news, now it's time for click. this week we're going flat out. spencer is on a building site to put up a house, although it looks like he's got away without doing any actual work. is there some banging at some point? yep. didn't even get my hands dirty. we also look into a crypto investment scam that seems to

be evading the authorities. and paul victor's factory, but where all the drivers? completely happy with the fact that there is a very large, very heavy piece of equipment driving around autonomously. the cars can go from 0 to 100 in four seconds. they are made of 80,000 parts. the brakes can hit 1000 degrees. this is formula 1. well, this year's season is getting under way and it is jam packed full of tech, and it's notjust the cars. yeah, it's all about the data these days. they collect as much of it as they can from on and off the track to help make decisions which could change the results, and alistair keane has been given exclusive access to the alpine f1 team to find out how they race.

being behind the wheel of a formula 1 car is a privilege. driving the fastest car in the world, the adrenaline rush is so high. it's a privilege because there are more than 1000 people working on our team. i'm the guy that's being granted the axis. that feeling of speed and the g—force you feel through the corners, due to the speed you are carrying, it is just so satisfying. what do you make of the car that's being unveiled behind us? well, i think it looks beautiful. in terms of evolution, i'm more interested in the changes and tweaks which have been done on that car compared to last year's. the front wing, the back of the car, which the engineers have changed

to improve the performance, so we need to get it to the track and see how it behaves. i guess every single team though is doing the same thing, they are all trying to push their cars and technology and everything, does it reallyjust level the playing field, or can you get a competitive edge? you can get a competitive edge as long as you always question yourself. technology evolves very quickly, it's a very fast moving world, and in formula 1, if you look at the cars from 20 years ago, ten years ago, five years ago, its continuous progress. hi, how's it going? good morning. thanks for having us here. here we are in what we call the design office, this is where all the engineers are working together to achieve maximum performance of these beautiful objects, these formula 1 cars.

lots of what is on people's screens in here is top—secret but a lot of it is about data. yeah, absolutely. you know, we are a highly data—driven kind of business because of regulation. those rules of f1 guide everything the teams do in theirfactories, from limiting how much testing the cars are put through to capping the money they can spend. that's why the team here are working with microsoft to gather analytics and make sure every penny is spent wisely. every time the driver is behind the wheel, we collect millions of data points. and then engineers improve that information and improve it into the best car of the next race. 0bviously that then comes to the factory we plan on that, we order it, manufacture it, we build it, and we test it. gathering all this information is also about speed. the team can respond to what is happening on track by making adjustments, getting new parts and getting them shipped around the

world in time for the next race, which is sometimes as soon as the next weekend. a few years ago, we had to wait until a certain time to access the data or after the competition took place to transform the data information. now, it's almost real time. the competition happens. at the same time we ingest the data, and that means that the results are immediately available. we are always trying to constantly improve. and obviously the difference get smaller every time. i think that actually makes it more difficult because we have to be more creative and the improvements and the ways we are going to be better. but it's notjust data from races being looked at. we've been given a rare access to the simulator where esteban 0con

is doing laps in anticipation of his next race. this is a closely guarded secret, with each team designing their own versions of this tech. how important is all the background stuff that happens away from the track? it's basically the same work we would do if we were testing on the track, so we have a replica of the model we have on the track itself and we are working to prepare ourselves the best to arrive on site and be completely ready. trusting the data is a big issue. how much do you trust what you're getting? i don't trust generally very easy so i do need some sort of proof. i will say it in my sport i do trust the team and what they bring to the track. whenever they bring something new to the car, my car is going faster. getting one tenth, two towns, and that's when you can be confident. you're going to see the progress. do you ever worry the data and the technology is taking away from the driving and the sport of formula 1?

not at all. no, because we are completely involved, we use data as well. time moves forward, the cars are getting more and more technology. this is formula 1, it's the peak of what you can do, the fastest machines on the planet. astronauts in space would have thousands of data as well, and for us it's the same thing but on the ground. hey, come on in, welcome to my new home. it's around 2100 square feet and it's packed full of curves and contortions. this place has such an unusual, futuristic feel about it, i mean there's not a straight wall in the place. you may find yourself wondering how do you make such curvy walls? well, if you look at them a bit closer, you might be able

work out the answer. this is so printing at scale. it's a largely automated method of manufacturing houses, and it's thanks to a fleet of giant 3d printers. they squirt out a layer of material and then they squirt out another, and another, and another. icon has partnered up with one of the biggest housebuilders in america to deliver 100 homes here in georgetown, texas. hey. you're connor? i'm connor. spencer, right? nice to meet you. welcome to the job site of the future. one thing i noticed is that's the only billing noises? correct. there's gotta be some banging at some point? there has to be banging? this is it. were not hiding anything.

now, the walls aren'tjust thin lines of concrete. there are multiple layers forming concrete columns to add rigidity. reinforced by steel, they are printed using a proprietary material, a cement—like substance that is air—tight while also providing increased insulation. i love the theme that they have going on with their naming system here. so it's not concrete it's the name of the system that mixes it magma, and the name of the machine that prints it is .doc ill or the machine is welcome. because we are liquefying ruck. but how easy is it to both be creative and cost efficient? the reason we exist is to be faster, cheaper, more resilient. the very awesome thing about 3d printing is it allows for you to do that at scale, so we're talking about delivering tens to hundreds of homes that can all be different in design and delivered simultaneously because the faster you can produce houses, the less you have to staff

those worksites and jobsites, and then you also have all the design freedom and flexibility that you can possibly imagine, plus you get a more resilient build material. its early days at the moment, so the actual speed at which houses materialise will vary. but some of the earlier houses are ready to be roofed. you have your primary bedroom here. master bedroom. right. being british, can i show you the most exciting thing about an american home? i'm guessing this is the walk—in wardrobe, the walk—in closet right? this is the walk—in closet! i have never owned a walk—in closet. no? no, no, no. i'd be in here all day. welcome to america, not only america, but texas, right? everything is bigger. what's really different about 3d printing is that all the permanent fixtures can be laid down at the same time. this includes things like the kitchen island and the holes

for plumbing and electrics. here is another strange thing. although some of the walls will be covered with tiles and the like, most of them will retain this rather unusual beaded texture. we are really proud of our beads. we are going to let them stand out and speak loudly. we want to accept doing them with some accent. just to be clear, you're not going to render this or cover this. this is going to be part of the what the residency? the show home we started in is called house zero, and that was designed by a different architecture firm. it's more of a show home for what could be possible in the future. it's not for sale, which is a crying shame, because it's definitely my kind of place. icon actually has ambitions that transcend these. nasa has awarded the company $57 million to develop 3d printers for the moon.

the next giant leap for humankind will probably be taken from some kind of moon base, which will most likely not be built from materials that we send up from earth. after all, the moon is not made of cheese, you know. the technology that is going to be required to rebuild the moon base with 3d printing is actually going to be a completely different form factor. it has to be. because the challenges of building there. so you are probably looking at something that is like a robotic arm that gathers local materials and then effectively melts them into place so you can continue to build on top of them. homes of the future have been ten to the dollar through the years, but actually, this is a completely new type of building technique which really could make a difference to the look and feel of our living spaces. and actually, my new favourite thing about how we're going to be living in the future is how we'll fill our baths. there's no tap in that tub.

instead, you fill it from the ceiling. actually, i have been reassured that in the future they will still have taps. time for a look at this week's tech news. first up, open ai has released gpt four. it is the latest version of its hugely popular artificial intelligence which powers chat box chat bbt. the new model is being used to supercharge microsoft's bing search engine as well as language learning app do a lingo. meta, which owns facebook instagram and whatsapp, has announced plans to cut 10,000 jobs. it will be the second wave of mass redundancies for the tech giant which laid off 11,000 employees last november.

and 128,000 jobs in the tech sector gone. so that really highlights just how big and how deep these cuts are. now, remember last week when we went behind the scenes of the graphics team at avatar, the way of water? james cameron's much—anticipated sequel has just won the academy award for best visual effects at the 2023 oscars. itv studios has teamed up with reality plus to launch a series of mini games, taking fans of the iconic tv show into the meta— verse. a special event will run for two weeks and give players the opportunity to join forces with their favourite thunderbird characters. it will let them eintracht around international it will let them interact around international rescue tracy island. crypto trading has becoming increasingly popular, often promising high rewards in short periods of time. but recently, the crypto market has been shaken by a flurry of bad news,

and a growing number of scams. i invested for one month. you could see every day how much your dollars to app is creating. so it looked quite professional. a clear example of today, we are announcing maintenance. this woman is from romania. she lost hundreds of euros when she invested in the crypto trading app called i am bart. she asked me not to reveal her identity, as she feels her professional reputation might be harmed. some other people started to say i could not withdraw and what is happening? i made the request and the moneyjust disappeared. so my dollar became zero, but i was never credited on my wallet with any money. in romania, dozens of high profile people during the art as it

was sponsored by a well—known it expert who invested his own money in it. the fact that in between us and the company there was a reputable feature, maybe we didn't check too much. we didn't doubt too much. this company presented as a us—based company with excellent credentials, but when we checked the website, a few red flags came up. the man they claimed who is the company founder told us he never heard of them. they claim they are strategic partners with mit, but their partners also told us they don't know them. what makes them interesting is the scale of the operation. the number of the investors is quite high. there are more than 800,000 investors.

this woman is an expert in romania. she has investigated imbot and collected victims complaints. the information she gathered was handed over to the fbi. when they have enough investors and enough money invested in a specific country, they close that country. they do not allow that country to withdraw money and they open other countries at the global level. the way this group of persons acted, it is closer to a ponzi scheme and not to a real business. in a ponzi scheme, investors are pushed to recruit more people to join the investment plan. but new recruits money pays for the diffidence of the people of the top. and when too many investors want to take their profits out, the scheme collapses. we have reached out for a comment to imbot, but they have not engaged with us.

in some countries, people still trust the app. here's a local investor for i earn bot. he and his current investors recruit more people. now with the throw stop since december, he says some have received threats. translation: people took loans to invest. they used money from other sources and many people were affected. as the leaders did not have answers, people started to get angry. with the help of an analyst, we managed to identify one crypto wallet that received payments from around 13,000 for a profit of almost $1.3 million in less than a year. but we couldn't identify the people behind this account.

i earn bot seems to be well organised professionally. so the question is, in cases like this, how can those responsible be identified and held to account? one of the challenges is to identify an attribute to who the illicit actor is, where the value is going, and then being able to take investigative steps and law enforcement action. so what advice would you give with people who are looking into this sort of investment? knowledge, and doing some due diligence before the investment process is critical. it's like anything else. if it sounds too good to be true, it often times it is. the fbi has told us they cannot confirm nor deny an open investigation into i earn bot. they have set up a new specialist team to investigate, among other things, this sort of scheme. but they insist the best way to defeat scammers is prevention.

now, despite all the talk, self—driving cars still aren't quite here yet. i mean, for good reason, they are the hardest autonomous vehicles to get right because they have to navigate the case of the open road which has drivers like me on it! you said it! but there are lots of vehicles that can drive themselves in more controlled situations and they �*re often used in the logistics industry. so back in austin, texas, paul carter has been to meet a company bringing the humble forklift up to date. yes, the humble forklift has been the backbone of global industry for over 100 years. and now they're getting a 21st—century makeover. here at fox robotics in austin, they've created what they call the world's first intelligent forklift.

beyond being just self—driving, it can unload and receive packages completely autonomously. so, we start with a standard counterbalance stand—up forklift. we add sensors for both perception, being able to understand the world around the forklift, as well as safety. so our primary sensors are... we have one camera right here between the forks. oh, yeah. it is both a depth camera, as well as a regular camera that helps the pallet detector so it can determine is that a pallet? what type of pallet is it? what direction is it? our other main sensor is we have three micro scan lidar, so there's two forkward and one, if the walk all the way around, back here, that's steer—ward. so that pretty much gives a 360—degree view.

on a plane about that far off the floor. this has safety rated inputs last outputs. so making decisions on where to go and what to do? yes. the robot can unload 25 pallets in an hour but there are limitations. it's really easy to build a robot that works once but to build one that works every single time, day in, day out, that's something that matters a lot to us. figuring out how to both meet the workflow needs that customers have and maintain our perfect safety record and be compliant with all the required standards is a real challenge for introducing any kind of new autonomous system into a workplace. being around them when they work is slightly unnerving at first. it's quite strange how quickly you get used

to the fact that this is just driving around by itself. i'm already completely happy with the fact there's a very large, very heavy piece of equipment, driving around autonomously. but what about the impact on jobs? 0ne complaint that all of our customers have is that finding labour for warehouses is just so hard these days. they need to hire more and more people. and most of these warehouses are outside of major population centres, so by augmenting the people that work in these warehouses with autonomous forklifts, you can get more done with less to stay competitive and get thejob done.

as the world changes and automation becomes more common, it's clear that innovation and industry face some conflicting times ahead. but in the brave new world, your next parcel delivery might have been on part of its journey thanks to one of these. we will have more in the coming weeks. thanks for watching. we will see you soon. this month has been quite wet, if you areas across the uk that has

seen more than the much average rainfall, the wettest place nearly 1.5 times as much as an average march and lots of rain to come. the wettest weather will be a crust west and north—west and it is, by the end of the month summit is rehearsing more than twice the average march rainfall. not bad today, some sunshine, the cloud thickening with weather fronts approaching from the west bringing rain to end the day and still with us overnight, so it wet night for northern ireland, northern england and scotland, further south makes you drizzle and across england and wales, mild night, 6—7 for most, cordial still and shetland foot should be a bright start to the day but lots of cloud and heavy rain for northern ireland, another batch of rain for wales and

western england through the afternoon. you might find brighter spells across eastern england are not much rain expected eastern angle, tempers day temperatures could reach 16. centring on heavy showers on tuesday, rain and to northern ireland with that in the day, more rain on the way, through tuesday pushing north and east, across scotland quite slow moving, then windy for wednesday, sunshine and blustery showers, hail and thunder mixed in and some showers across the western areas could emerge for longer spells of rain, windy withjust 40—60 emerge for longer spells of rain, windy with just 40—60 across the north west. staying windy through thursday and again very unsettled, showers widespread and some of them hail and thunder, building sunshine between downpours. temperatures

mostly into double figures but getting cooler in scotland, may be some snow on high ground rent friday at the weekend staying and settled with more rain on the way, rainfall totals mounting up.
