this is bbc news. the headlines: russia is claiming a rare victory in what's become a war of attrition in ukraine. it says it's captured the eastern salt—mining town of soledar, though ukraine says fighting is continuing. the town had been pumelled for weeks in one of the most intense battles of the war. brazil's supreme court has decided that prosecutors should investigate the role of the former president jair bolsonaro in the storming of congress. the violence was carried out by thousands of radical bolsonaro supporters who continue to claim that october's election was rigged. the former president is in florida. the manchester city footballer,

benjamin mendy, has been found not guilty of raping four women. the jury was unable to reach a verdict in the cases of two other women he was alleged to have attacked, so he will face a retrial later this year. now on bbc news, it's click. let's get 2023 started in style. welcome to las vegas,

where there's lights, sounds and a whole lotta shakin�* going on. uh, not sure this is what they meant, though. did that make you feel better? trust me, it made me feel everything. yes, everyjanuary, the tech world heads to the massive consumer electronics show, spread throughout the las vegas convention centre and surrounding hotels. it's great to be here, back in our studio, overlooking part of the show. yeah, only part, though, because this place is big. how big? very big. to give you an idea of how huge, i'll tell you what, should we give them a whistle stop tour? i'll go that way, you go that way, i'll meet you halfway around. deal. all of the halls have pretty spectacular stands in, and you even get a bit of a theme in each one. this is the north hall and i'm getting health care vibes from this place. here at the venetian expo is my favourite bit, eureka park, where some startups get small stands to step out their big ideas.

the west hall is shiny and new, and this is where all the car stuff is. and now we're in the central hall to try out some haptic gloves that mean, when you touch things in virtual reality, you can feel them. here, shake my hands. hello? that's so weird! laughs you're tickling me. iam! have a little tickle. do you fancy a jenga battle? sure, why not? all right. you could feel the blocks as you pick them up! that is really incredible. you could drop them on your hand and feel. 0h. as i grip this book over here, i can actually feel resistance. so as i try and squeeze it, i'm being stopped, which really gives me the impression that there is a solid thing between my hands. it's the air pressure that's used in there at 135 sensing points, so you can feel every little bit of movement.

oh, my fingers are doublejointed. we've forgotten to do thejenga. this is much more fun, actually. we have. let's move this out of the way and play the game. yeah, 0k. i've got to fix this. you're not doing it right. here we go. oh, oh, 0k. that's actually a bit tricky. i tell you what. .. i don't have as much control as i should. i tell you what i do when i lose, is that. oh, no. i'm going to prod you for that! laughs so the use cases for this are suggested to be, first of all, training, so you can train people to use equipment and they get an idea of how it feels. also design. you could design a new car, for example, and run your fingers over the body before it actually exists. big leap forward for haptics, would you say? yeah, i would. big difference from anything i've used in the past. it really is good to see ces getting back up towards its pre—pandemic size. the question, of course, is whether these big expos have permanently changed

as a result of covid. the person who is responsible for bringing this as this person. thank you for coming. ces 2021 it didn't happen in the rails. 2022 was a lot smaller. this feels like it that back to normal. this iucn? after three _ that back to normal. this iucn? after three years _ that back to normal. this iucn? after three years of _ that back to normal. this iucn? after three years of the - after three years of the epidemic, this feels phenomenal and the — epidemic, this feels phenomenal and the excitement, the crowds. one of— and the excitement, the crowds. one of the — and the excitement, the crowds. one of the big trends this year? _ one of the big trends this year? every company is talking about— year? every company is talking about efficiency, sustainability and leaving a better_ sustainability and leaving a better world for our kids and grandkids through technology. we are — grandkids through technology. we are in a cost—of—living crisis, an energy crisis and climate crisis. do any more expensive, power hungry carbon emission devices? zt} expensive, power hungry carbon emission devices?— emission devices? 20 frame the auestion emission devices? 20 frame the question that — emission devices? 20 frame the question that way, _ emission devices? 20 frame the question that way, i _ emission devices? 20 frame the question that way, i don't - emission devices? 20 frame the question that way, i don't know| question that way, i don't know the answer but we need solutions to fundamental human problems in healthcare, energy efficiency and things like that

if your attorney rental car, buying a car have an insurance claim, it can do some of the work for you. let me show you how it works. you start your scan like this and where there is damage there is some here on the door, zoom in and it should identify what the damage is. don't on the front door, yes, you can either approve it, edit it or deleted. if i keep moving around i'll take a closer look at the tires. it is to ensure you have the whole car and shot and it takes some photos and when you finish it will beauty shops, as well as a as they come around to decide, it tells me thejob is done. simple. amongst the screens, cars and other weird stuff here there are plenty of home appliances. some can remove around by

themselves these days but have you wondered how they find their way about? many of the modern ones you something called simultaneous location and mapping. in short, slam. modern, domestic and industrial robots arejust bump modern, domestic and industrial robots are just bump and go. the need to build a map of where they live to make sure each spring—cleaning isn't a brand—new voyage of rediscovery that means they might forget the occasional nook and cranny. a one common way to scan your surroundings is lidar which uses a spinning laser to determine the distance to everything around you. but lidar has its shortcomings. the problem with lidar is if you want high performance, they're extremely expensive, can be thousands of dollars. so that's not going to cut it for commercial products at all in the consumer space. but then the low cost ones, which you see on many of the consumer products out there, just are very unreliable. the degrade over time and they also capture a tiny amount of spatial information compared to the amount of information you

capture with a camera. we're able to access that spatial information, but using very low cost processes and silicon. this vacuum robot is running new software developed by slamcore, which builds up a map using vision instead of lidar. this allows the software to more intelligently work out notjust how far it is from stuff, but what that stuff is and whether it's likely to stay there. when it knows where it is, it needs to know what are the obstacles in its way, where is it free space, is it going to crash if it tries to go through a certain space? the next level of spatial intelligence is knowing how the world around you is shaped just from a geometry point of view so knowing what's occupied space and what's not. once the software's labelled everything, it can do different things with the information. for example, if it's committing the layout of your flat to memory, it might want to remove objects it knows

aren't permanent, like books, other stuff that's strewn around, or even people that it's encountered on its travels...like me. don't worry about the look of this particular vacuum bot. at the moment, it's wearing a low cost stereo camera and inertial sensor on its head but the plan is for these to be integrated into vacuum cleaners, drones, and other autonomous devices in the future. the point here is that a few low cost peripherals are all devices like this would need to collect enough data to feed owen's software, which is the real breakthrough here. a really small, tight, neural network lightweight enough to be stored in the device that can label everything and work out how to respond to different types of objects. one of the big benefits of a robot or a machine knowing the objects it's encountering is it may choose to modify its behaviour depending on the type of object that is. so, for example, a drone may see a person and want to keep a really wide berth

because there could be a safety risk there. but if it's going to get through a door or somewhere a bit more narrower where there's only inanimate objects around, then it can have a much smaller safety margin to be able to make it through. plenty of ways, then, for a new way of navigating the world to help you to clean up. lara: honestly, this is the first time i've ever seen him do the chores. another big theme this year has been tech to help disabled people. paul carter has toured the show floor with one woman who's created a way to help people with low vision see the world differently. these formulations played a major part in getting back to normality. this instructs yourselves to create their own.

another for dealing with viruses something that has been researched for a while the treating cancer. and moderna announced positive results of a phase ii trial from announced positive results of a phase ii trialfrom its personalised mrna cancer vaccine. i've been talking to the ceo of moderna and asked him what he thinks is going on. i think as we move away from chemotherapy and into immunotherapy and personalised immunothera py and personalised treatment, immunotherapy and personalised treatment, i think we will see less side effects of what we saw with chemo, which was very drastic, it was a big hammer on everything and very hard to cancer patients. what we know today which we didn't know 20 years from now is that cancer is always a disease of our dna. it's a mutation in our dna. it's a mutation in our dna. it's an empty dna that you have, so what we do then is we make a product one human being, so we get the robot to make

product for one human being at a time, with about 60 days, we launch, around 30 days, from the biopsy to you getting it in your arm, the biopsy to you getting it in yourarm, like a the biopsy to you getting it in your arm, like a covid vaccine, getting it in your arm, the medicine madejust for you, your cancer, the design phase on the sequence.— your cancer, the design phase on the sequence. then is at one vaccine, on the sequence. then is at one vaccine. a _ on the sequence. then is at one vaccine, a series of— on the sequence. then is at one vaccine, a series of vaccines? i vaccine, a series of vaccines? how will the process work? it's a good question. we try in the clinic where we show a 44% reduction, embed to the best drugs available in the uk or us. with all technology. it is nine injections intravenously, just in your arm, and then you are done. but what was shown is that we think three or four might be enough. so we still had to do a phase study to make sure we keep the good data but then we do a lot of studies to see if we can shrink it, to only three orfour.

see if we can shrink it, to only three or four. decision medicine — only three or four. decision medicine is _ only three or four. decision medicine is obviously i only three or four. decision medicine is obviously the i only three or four. decision i medicine is obviously the dream but whenever i look at it before and other stories it feels like we're at the very of collecting the kind of data that can make a huge difference in the future, but right now it's quite challenging to make a difference with it, isn't it? what's very as exciting as we know this study is real, it was powered, 150 people and the statistical value is very small so any data, we are all super excited because this is real. what other cancers are you hoping to treat? i what other cancers are you hoping to treat?— hoping to treat? i think obviously _ hoping to treat? i think obviously melanoma i hoping to treat? i think obviously melanoma is| hoping to treat? i think. obviously melanoma is the hoping to treat? i think- obviously melanoma is the next big one. kidney, breast cancer. colin is a good one to try as well. we're going be very aggressive and modernise well, there is a lot of cachet, so we're notjust try use the capital, but also to grow a lot of things at the same time. i don't want to try one thing after the other, all at the same time.— after the other, all at the same time. ., ,, i. , . same time. thank you very much, reall , same time. thank you very much, really. really _ same time. thank you very much, really, really interesting. - really, really interesting. another big thing this year has been tech to help disabled people. paul carter has toured

the show floor with one woman who is created away to help people with no vision see the world differently. this is rebecca. she's visually impaired and navigating herfirst ces. she's the creator of an app to help other low vision people navigate the world better. i have a rare disease called albinism, which basically means that my body doesn't create enough pigment or melanin, which is why my hair, skin and eyes are the colour that they are. in addition to that, it affects the development and the maintenance of proper vision. as a result of that, i have really an uncorrectable impairment where no amount of glasses or lasik or really any current treatments can aid the problems that i have. and what i found growing up and as a student is that there

really was no assistive technology that was appropriate for someone like me. but i have trouble sometimes during normal everyday tasks, like reading the posters here at ces. the app makes it easier for people with low vision to see things around them. it uses customisable smartphone camera filters that users can change to suit their own unique visual impairment. because i have an impairment, it's really easy to fall into the trap of saying, well, i know what's best for these people. i know what they need or what they want. our rebokeh app spent about a year in beta with about 100 beta users, where our sole goal was to solicit feedback from people with vision impairment, optometrists, ophthalmologists. and over the course of that year we added or adjusted more than ten different features. how might be useful for looking at something like this?

yeah, so i can totally show you. so this is actually really hard for me to differentiate, especially because there's so much going on right here. there's just a lot of images. so what we can do is actually point it up and with one finger — it's meant to be one handed — so with just one finger i can kind of zoom up and in. so let's pick one to look at, maybe this picture of a computer and whatnot. what we can do is we can actually add some contrast... oh, wow. ..to make things a little bit brighter. the light�*s a little bit lighter. we can also add actually colour filters. so this particular screen has a lot of green on it. so there's a whole lot that we can kind of do to... see, now, everything's kind of green. but to kind of make certain colours or certain features pop out a little bit, you know, now i'm kind of understanding what this company does, whereas before it was just a whole lot of chaotic kind of images. in a way, it's quite a simple process, but i can imagine it's

quite liberating just being able to instantly be able to point your phone at something and see something differently. absolutely. for a lot of people, it's the difference between being able to read a menu at, you know, starbucks or mcdonald's when it's up in the back and needing to ask somebody else for help. and, you know, if you're by yourself, sometimes that's totally an independence issue. the app is currently available for iphone and ipad, but rebecca also has plans to make rebokeh a community for visually impaired people. there's about 25 million people in the united states alone with some type of moderate, uncorrectable vision impairment. and we're super excited to be able to also showcase and bring awareness to that population, to give those people a space to come and gather and say, we have our own very unique set of life experiences and needs and challenges and wants, and to give them an opportunity to come together with people more similar to them to talk about those things is really what we ultimately want

rebokeh to grow into. that was paul. theseus is full of tiny —— shiny tech companies but also human stories as well. that's all we have time far from vegas or should we do more next week?— next week? more from here, thanks next _ next week? more from here, thanks next week. _ next week? more from here, thanks next week. goodbye. | hello there. well, so far, january 2023 has been very wet indeed, with above average rainfall for many. we've seen some localised flooding. river levels running very high, some of them breaching their banks altogether across southern and western parts of the uk, so a number of flood warnings continue,

remain in force across the uk. head online to see where they are. however, as we move through this weekend, the rain will clear away. we'll turn a bit brighter but a very different feel to the weather. for part two of the weekend and into next week, things are set to be much colder. a risk of ice, snow and frost. now, this area of low pressure brings wet and windy weather across much of the uk to start saturday. early on saturday, that rain will be very heavy and persistent across southern western areas — up to 70 millimetres of rain. in fact, the northern half of scotland will see clear spells and scattered showers, which will be of a wintry flavour as it will be cold here, but milder further south. it's a very wet, windy start to our saturday morning across much of the country. then, that rain will tend to clear away but it'll leave a legacy — standing water, atrocious road conditions exacerbated flooding as well across some southern and western areas, but it brightens up into the afternoon. plenty of showers rattling through the northern half of the uk. wintry on the hills. it'll be colder here.

the last dregs of the milder air hold on across the south—east. but it doesn't last through saturday night. the colder air wins out — clear spells, blustery showers, long spells of rain across the northern half of the country. increasingly wintry, notjust to higher ground — even down some lower levels across northern scotland. it will be a chilly night across the board. so, sunday's looking colder. we're all in that arctic air. then, you can see from the blue colours here, the white speckles indicating snow showers, which will be affecting primarily the northern half of scotland. this weather front will bring a mixture of rain, perhaps a bit of sleet over high ground for parts of northern ireland into parts of north wales, north west england, into the midlands as well. elsewhere, plenty of sunshine, top and tail of that weather front. but there will be some snow showers feeding into northern scotland, some of these down to lower levels as it will be a cold day right across the board. single—figure values there. factor in the wind, it'll feel even colder than that. so, into next week, it stays much colderfor a time. the risk of overnight frost and ice, an increasing chance of snow in places. some of that snow might be disruptive sunday night

into monday, particularly across central and southern parts of the uk, so stay tuned to the forecast. but the general theme is as we move through the week, temperatures begin to recover again towards the end of the week.
