this week, alasdair sheds light on the tech behind these dazzling sd displays. something's hand's just come out at me. yeah. — it's like a possessed hulk. lara's been checking out the latest health gadgets, including those fending off the calories and those fighting off hair loss. you've got great hair! are you going to tell me you were bald before? and paul heads to the racetrack to see the high—speed cars that don't have human drivers. hey, welcome back to las vegas. this is one of the most famous skylines in the world. and one thing about this sight is it's constantly changing. see, whenever they get fed up with a hotel, theyjust gut it and turn it into something that looks completely different. but in the last year, something really unusual has lit up the horizon, literally. it's that thing over there. yeah, it's called the sphere, and it is a monster. inside, it's an entertainment venue. outside, it's the world's

largest video screen, covered in 1.2 million leds. and it's become an instant landmark and a huge talking point since it opened last year. in a few moments, we'll find out what it's like to live in a city that's dominated by this giant, glowing ball. but first, alasdair keane's been taking a look at how graphics are bringing it to life. our senses are constantly being bombarded by the sights and sounds around us, including advertisements that have been carefully crafted to grab our attention. but in a busy world... ..do we always notice? if everyone is looking at their phone, what we are trying to do here is to convince people to stop looking at their phones and recall what they have in front of them. bcn visuals are based in barcelona, creating sd displays

all around the globe, and now they have a new canvas to work on. and it isn't without its challenges. what we did is think about "round". you know, round things, round shapes, so we can place in there and it would look like we have done something specifically for this. when it came to the storyboards, it was quite challenging. instead of doing the pre—production on this round sphere, we made it look as if it was flat, so it could be easierfor us to think about ideas. and wrapping the content around the sphere wasn't enough. we needed to make it look like...the sphere would open up as if it was a gate, and it would show you everything that it's got in the inside. mechanical clunk the company made its name over the past few years with campaigns in new york's times square and other major locations around the world.

they specialise in a technique which creates the optical illusion of three dimensions, but now that's taken to the next level. i mean, it's huge. people can't miss it. it's huge. you have to get what's on the screen right as well. yes, it's huge. every little detail is a three—metre detail. you know what i mean? like, it's not like, "oh, there was, like, a kind of mistake. "let's hide it with this or let's add a layer." you cannot do that. everything needs to be perfect, and it needs to be seen from all angles, even from a plane. this is a lucrative ad space which can cost hundreds of thousands of dollars a day for companies to take over. to achieve their complicated design process, bcn visuals brought in talented sd animators from hollywood to help bring the characters to life.

stephanie katritos has previously worked on movies such as shrek and antz. how much of it is in tricks in the animation and what you can do with technology, and how much is it just, you know, standing with the lights hitting the screen a certain way? we have a bag of tricks we use. yeah. it's an illusion. and we are illusionists. like, that's really... that's our magic. that's what we do. we've worked on these screens multiple times. we really understand the screen, and the point of view, and what's going to work the best for that screen. so we try to find those few moments where we can break the fourth wall. we use a lot of different techniques depending on what the brand needs. so we can layer effects over that, also sd characters on top of that. it's about building up a world, and we use everything — effects, lighting, animation, compositing, editing, all of that — to enhance the image.

yeah. you want people on the street to have a sort of wow feeling, or some sort of emotion... yeah. ..through what they see. a surprise, a connection, just an amazement. you know, "wow. how did that happen? "i don't have a pair of sd glasses on." with their displays so big and hard to hide, the team don't get rehearsals. so to help make sure the illusions work, they use virtual reality to experience and test their creation. one of the big problems we have i is when we are about to deliverl the campaign, we have to test it. the clients want to see it, - our team wants to see it, and, of course, watching it on a flat screen is not the same. - so we decided to replicate the areas we're doing — i for example, times square — every detail as possible, - so then the clients and our team can experience exactly _ what they will see, like a live testing. i yeah. and i can have a show of it as well? yes, of course. go for it. oh, wow.

so i'm in times square now. yeah, that's right. and now you should be seeing the avatar campaign. - so, now... yeah, the video's happening. so this happened in is... oh. wow _ so they've just jumped out the water. yeah, that's right. and the water's gone everywhere. something's hand's just come out at me. yeah. it's like a possessed hulk. ooh! that was cool. when i'm meeting with some advertising agencies, people spend most of the time trying to come up with a good slogan. in our case, i always tell them, "there's not much time to spend "on thinking about a good slogan," because first you've got to grab people's attention. the story is even more important than in a two—hour—long movie — selling a shareable moment that people want to record and want to share with their friends, but also on social media. and that is the secret as to why companies are willing to pay

so much for this ad space — not the people who will see it actually in vegas, but on videos shared all around the globe. james: the sphere looks pretty cool inside, but it's the exterior that's really caught people's attention. powered by over a billion leds, it's attracted massive amounts of hype, like this enormous eyeball or the lunar surface. it really is impressive in person. so, what next for the sphere? well, if you'd asked me that a few weeks ago, i would have said london. but there's been a bit of a problem. this car park is the site of what the owners of sphere, madison square garden — or msg — wanted to put the next sphere. it's in stratford in east london, and it's an area that's seen huge amounts of investment since the olympics

was held here in 2012. the problem is, is that stratford definitely isn't las vegas, and it's caused quite a stir here, mainly because the site is really close to where people actually live. so where is it? shall we try and peer over? yeah... it's hard to actually even find a place to look at the location from the ground, as the mayor of newham and i found out. you can peer through here. oh, yeah. you can see the site through there... ..and it's really, really, really constrained. you've got chobham, then you've got a major housing development there, you've got a housing development there, and obviously you've got shoppers there, and then you'll have this big, huge... right. ..globe. it would just be this entire bit of land. ceren sonmez is a resident whose apartment block would have looked directly over the site. could you imagine you're sat here, i'mjust, like, working from home

or i'm just chilling, and there'sjust an eyeball, like, rolling around, looking around? like, it sounds like a nightmare. so any time i don't want to see that, i should close all of... yeah, block every single window to not be seeing that? that's not a good solution. it's particularly problematic because ceren collects plants. having your blinds closed all day isn't exactly ideal for that hobby. what msg say is that, yeah, stratford is different to las vegas, but that's reflected in what they want to do here and that the screens that would be built over there would be turned off late at night and early in the morning. as you may have noticed, i'm talking in the past tense about this application because, earlier this month, msg pulled out of london after the mayor of london rejected the application because of light pollution. that's great news for ceren and her plants, but is it good for london? msg didn't want to be interviewed for this piece, but it did say that...

las vegas�* visitors authority, though, seem more than happy with the sphere and are kind of excited that it's just in las vegas for now. from vegas's perspective, when you look at the skyline, when you look at the strip, it fits in perfectly, it has created a lot of extra excitement. you know, any time you can debut a new offering in the destination, it helps keep vegas top of mind, it gives our visitors a new reason to return. and so, selfishly speaking, it's fantastic that it's here and only here, giving us the opportunity to delight our visitors when they come here. the sphere almost feels

like a homage to light, and it really is impressive. and las vegas feels like the perfect place for it, too. but the problem sphere has is las vegas is so atypical as a city. it's basically a city of light anyway, and it's glamorous and glitzy. people want this kind of thing here. but sphere�*s problem is that most cities just aren't las vegas, and it's going to have to find a way to operate these spheres in major areas where people actually live. and that is a bit of a conundrum for sphere. amazon has been fined s2 million euros in france for surveillance of workers. the french data protection agency says it tracks employee activity so precisely that workers potentially have to justify their breaks.

amazon disagreed with the findings. the new hampshire attorney general�*s office has said thousands of phone calls claiming to be from us president joe biden were scam calls using a ai—generated voice. on the call, the president allegedly told voters to skip the recent primary elections in the state. republicans have been trying to push non—democratic voters to participate in the primary. what a bunch of malarkey! the president has said there are risks with deep fakes and fake images and misinformation can be exacerbated by emerging technologies and that is why this president has directed the department of commerce, through the ai safety institute, at nist to help deliver clear watermarking and content. japanese space agency officials are scrambling to understand how its robot called slim

successfully landed on the moon but now cannot generate electricity through its solar cells. the robot is currently relying on batteries to communicate with the agency. last week, we brought you some of the highlights from the consumer electronics show here in las vegas, but we couldn't fit it all into one programme, so we have more from those tech—laden aisles — including some of the latest innovation hoping to monitor and mend our health like never before. well, this device, which is the withings beamo, might be able to help us for some remote doctor appointment data. now, instead of having all the kit that you might find in a surgery, well, it does the basics like temperature — there's a sensor that works just like this — you can also take an ecg byjust holding your fingers here, and it will also provide you with your blood oxygen levels. the most exciting feature, though, is that this works as a stethoscope — i know it doesn't look much like one.

now, it syncs to an app that'll give you instructions as to exactly where you're meant to use it. you rub it across your skin and it'll take recordings. those recordings can then be sent to a health care professional because the chances are we can't really interpret them ourselves. you can listen to them through a pair of headphones, but this is reallyjust hoping to enhance the remote doctor experience with some of that vital data that you otherwise can't really provide. it's also another of a growing selection of health care products that help you be able to take regular readings instead ofjust those ones that you might do in a doctor's surgery. it should be available later in the year. and when it comes to getting a full picture of our health and wellbeing, medical gizmos and wearables can't do it all. you might also want to be aware of exactly what you've eaten, and it can be quite hard to input that data, especially when the weight of what you're having needs to be put in. so here is caloai, a system that allows you to photograph what you're eating and it should be able to work out the content of it. it's not the most exciting of meals

— just a bit of lettuce and chicken, so only 200 calories in there — but it also breaks down the ingredients. so you can see here the information for the lettuce and, here, the information for the chicken. it is also trying to assess how much you've had of each, which may be a little bit easier, if it's accurate, than trying to quantify it yourself. also, you can store all the data in here, so it means you can hang on to what you've had and even how much you've enjoyed it. not that i imagine that meal would have scored so well. elsewhere on the show floor... this device is trying to solve a problem that i think a lot of people would like a solution for. niostem is trying to overcome baldness. it's suitable for men or women and aims initially to prevent further hair loss, but after three months, it is claiming that it can start to rejuvenate the hair again by stimulating more hair growth. if this works, well, it could be quite something. you pop it on just like this

and wear it for s0 minutes a day and just get about your normal business — if you don't mind having this on your head, that is. this uses bioelectrical stimulation. how does it work? well, we are creating a gridwork on your head by pulsing with millisecond pulses through your entire scalp, thus energising and activating your hair follicles. the technology comes from wound healing and we cross applied it to hair growth. how did it do in the trials? it performed, actually, very well. we had a six—month trial and it showed that it was six times better than the leading drugs. you have great hair. are you going to tell me you were bald before? i had good hairfrom the beginning, but i worry a lot about it and i use it also every week. right, ok... i wasn't serious, but that's good. anyway, onto those who are hairier than most of us. it's notjust about us humans. this is minitailz�*s latest device. you can think of it as a smartwatch for dogs — not that it's worn on a paw. it's actually worn in the collar here. now, the company has had previous devices that have tracked activity,

but this time round, it's all about health, including monitoring for afib, which is an irregular heart rate, which can happen quite often in smaller dogs. it's suitable for dogs of all size. and then you can take a look at all of the data on a phone. then, all of that information is stored within the app. it's a mixture of the health data, plus what else this sensor is picking up. so it's also identifying whether the animal has been eating or drinking — and how often — and if it's been barking, maybe when it's left home alone. there's one sensor in there which manages to identify a lot of different things through the ai system, which is going on in the background, where masses of data is being crunched. and they're just some of the ideas showing how all of our future health could be better logged, recorded and predicted as mass data and ai come together. now, car tech was everywhere

at this year's ces. we had demos on the show floor as well as across the city. paul carter has been to see a race with a difference. these are no ordinary race cars. and despite the smooth overtaking, these racing manoeuvres aren't all that they seem. i'm at the las vegas motor speedway, and this is the indy autonomous challenge. and none of these cars have drivers — well, not human ones, at least. indy autonomous challenge

is a research initiative where we bring universities from around the world and companies that are working in the autonomous vehicle space, and we try to advance the technology through the platform of motorsport by running fully autonomous race cars with al drivers that are coded by top research university teams. the idea is to try to prove that autonomous technology can work at extremely high speeds. what you'll see is fully autonomous race cars racing each other, two at a time, passing each other at increasingly higher speeds until one car either crashes or gives up. and we can say that because there's no driver in it, so if it crashes, itjust costs some money. and, you know, the speeds that we've achieved in the past at this track have topped 180mph. this was a test day, where the various teams from top universities around the world

were tweaking both the cars and their ai drivers to try and gain maximum advantage. so what exactly are the challenges in trying to make an ai racing driver? well, there's multiple challenges, right? first is the perception, so getting all of the sensors, the lidar, the radar, the cameras to all work right. you have the communication technology, so how do you have really low latency communication? if the cars are moving that fast, you need to stay connected with them all around the track. and then there's the uncertainty of what the different ai drivers are going to do. so if a car is driving by itself, that's one challenge. if you put a second car or even a third car out there, now it has to predict what the other driver is going to do and that can be really difficult from a computational standpoint. everything that the opponent does, our car has to react to in real time the same way a race

car driver would. as the car changes lanes, as it makes decisions to try to overtake, we have to predict and adapt and move in order to make real—time decisions that could cost us the win or the loss. the challenges to making race cars race autonomously is exactly the same challenge as having a human do it. as you can tell, there's a very small percentage of people in the world who can actually race these cars, and imagine getting a team of software engineers together and to try to make that a reality in software that's making decisions in real time to compete against other software that's making decisions in real time. so it's not a trivial task. like regular autonomous vehicles, the race cars in the iac rely heavily on lidar to identify their surroundings. one of lidar�*s big advantages is that it can operate in low light. and to show this capability off, the main event of the track week was pitting the ai cars against each other completely in the dark.

but as fun as watching self—driving racing cars hurtling around in the dark is, this isn'tjust about entertainment. there is a serious side to all this. the main goal of this project is to advance understanding around vehicle autonomy, with the aim of ultimately making self—driving cars operate more safely at higher speeds. much of the industry has focused on low speed automation, kind of the urban, suburban robotaxi. we saw that — and in 2021, we came out with a new challenge to say, "what if we could prove that this technology could work at speeds, let's say, greater than 100mph?" and we think this is really important because, eventually, if we're going to have autonomous vehicles, we really want those vehicles to keep us safe at speeds that humans are not really comfortable driving. and once you get to 100 or 1s0mph,

unless you're a professional race car driver, you really shouldn't be driving at that speed. but think of what it would mean for the world to have cars moving people, moving freight at those kinds of speeds. the indy autonomous challenge is now expanding outside of the us, with races at iconic motorsports venues such as monza in italy and goodwood in the uk. autonomous driving technology continues to develop at speed, both on the road and on the racetrack. that was paul. and that's it from us in las vegas. we've had a blast. we certainly have. thank you very much for watching. hope you've enjoyed it, too. we'll see you soon. bye—bye.

hello, there. the week ahead is going to be a battle between warm air and cold air. on sunday, the warm air was firmly in place, helped by a southerly wind and some sunshine. the temperature in highland scotland, close to 20 degrees. and if confirmed, that would smash the previous temperature record forjanuary in the uk. the warm southerly winds came ahead of this weather front here, that's cleared away from scotland and northern ireland. the winds have dropped and following that band of cloud and rain, things are turning much colder. so much so that in the northern half of scotland we could well have a frost overnight. whereas ahead of the band of cloud and rain across england and wales, it's a much milder start. that rain could stick across northern england and wales through much of monday. quite heavy rain actually

falling over the hills in the north west of england. most of scotland, northern ireland looks like being dry with lighter winds and some sunshine. but this time, temperature are going to be much lower, typically seven or eight degrees, whereas where it's dry through the midlands and southern england, ahead of the rain, temperatures are still mild at 1a, maybe 15 degrees. not just rain, though. there could be some snow overnight, briefly over the southern uplands leading to icy conditions by tuesday morning. by this time, that low pressure has taken the wet weather away and we're left with a cloudy start for england and wales. sunshine across scotland and northern ireland will push its way southwards across the uk. and whilst we could make temperatures of 12 degrees in the southeast, i think about eight is going to be more typical in the afternoon. so, it's getting a bit colder from the north and then we've got some changes again for the middle part of the week. looking to the north again, we see more isobars, some weather fronts, it's turning wet and windy, particularly in scotland. widespread gales here

and across northern ireland, the far north of england, really strong winds are in the far north of scotland. but over the highlands this time we could see a couple of inches of rain. that wet and windy weather affecting scotland will push down into northern ireland, england and wales looking generally dry. much, much lighter winds in the south, some sunshine and temperatures reaching highs of ten or 11 celsius. now, the weather front bringing that rain moves southwards. the rain becomes much, much lighter, dying out. the winds do tend to ease and then change direction in time for thursday, behind that weather front there. and we may well start chilly across eastern areas, with some sunshine, but it clouds over from the west. a little light rain or drizzle over western coast and hills. and most of the rain is going to be across the north and northwest of scotland, and gradually, temperatures will be rising back up to around 12 or 1s, typically. and that's because we change the wind direction. we pick up more of a south—westerly wind, which will blow mild air across the whole of the uk. but because it's a long sea track, there'll be a lot of cloud to end the week and most of the rain i think will be across scotland again. not very much, but again

it's dry in the south, maybe some sunshine and we end the week with 1s or 1a degrees. so very mild on friday, but things are likely to change again during the weekend. we're going to find colder winds then moving down from the north and through next weekend and beyond, we may well stay in that colder air across the northern half of the uk, with some wintry showers, particularly in scotland. southern parts of the uk, not quite so cold and eventually, we may actually even see some rain coming into the south by monday or tuesday. bye for now.

live from london. this is bbc news. three american soldiers are killed in a drone attack near the jordan—syria border. president biden blamed iranian—backed militants and has warned of retaliation. mourners gather after a 15 and 16—year—old are killed in a stabbing attack by a group of people in bristol. israel says negotiations in paris over the release of hostages in gaza — and a possible new ceasefire — were �*constructive�*, but �*gaps remain�*.

the islamic state says it was behind a shooting on an istanbul church, that left one person dead. hello, i'm nicky schiller. we start this hour with the news that three us have troops have been killed in a drone attack on an american base near the jordan—syria border. us officials say more than 20 other personnel were injured. president biden said the attack had been carried out by an iranian—backed militant group operating in syria and iraq and vowed reprisals. as yet, no group has claimed it was behind the attack, and we have had no word from iran. jordan — a close ally of the us — has condemned what it called a terrorist attack and says its cooperating with the us to secure the border. our north america correspondent will vernon has more on the us reaction to the strike.
