good evening. this is your update from the bbc sport centre. liverpool put their premier league woes to one side as they got the better of wolves to make the fourth round of the fa cup. there were four other ties this evening, including some late drama to knock out the former winners wigan. joe lenski reports. for liverpool, this was third round relief, a breakthrough in a tough spell and a first win of the new year. for now, at least, the smile is back there. gloom would lift in a match where briefly the lights went out. when wolves resumed, they gave liverpool a sighting. their 19—year—old midfielder took this tie on by himself,

oh, what a strike! elliott last scored in october, the same month his team last kept a top flight clean sheet. but this time at molineux, they were resolute. wolves�* few chances slipped by and liverpool could plan ahead in the fourth round, they face brighton who beat them 3—0 at the weekend. you've got a smile on yourface at last. how much did you enjoy that? a lot. that's a pretty rare feeling. it feels like ages ago that we had that feeling that we win and play well. yes, we have to fight hard in the end. of course, that's the nature of the competition. forest green are in the third round for the first time in a decade. this was their first try at birmingham city. no waterlogged pitch this time, the team bottom of league one did this. oh, it's an absolute peach of a strike. but a cotswold curler brought a fight back from the city boys.

birmingham scored twice and stopped the knights best chance of an upset. the championship side played blackburn next. the team with third round regret are chesterfield, who went to championship west brom and got swept away. the non—league side were seconds from a win in the first game, but their moment had gone. a 4—0 win for the baggies in the replay and for chesterfield, a cold and cruel night in the cup. joe lenski, bbc news. the british billionaire sirjim ratcliffe�*s firm ineos say they've formally put themselves into the process of buying manchester united. united's current owners, the glazerfamily said in november that they were considering selling the club as they explore strategic alternatives. ratcliffe made an unsuccessful offer to buy chelsea last year after roman abramovich put the club up for sale. but his process is likely to be conducted, or this process is likely to be conducted in a very different way. now at the australian open, andy murray said he left it all out there after winning a five set match

against 13th seed matteo berrettini in just under 5 hours. it was a stunning first round performance from the 35 year old who held a two set lead before his italian rivalfought back to level at two sets all. murray saved a match point in the deciding set before defeating the 2021 wimbledon runner up in a tie break by ten points to six. well, joining murray into the next round is british number two, dan evans, who beat facundo magnus of argentina over four sets. the match was suspended at one stage due to high levels of humidity and temperatures of 37 degrees. evans will facejeremy chardy next or tomorrow morning. british number one cameron norrie will play francis constant lesbian british number one cameron norrie will play francis while emirati keanu is up against the american seventh seed coco gauff. former british number one annabelle croft says it could be a great watch. it's going to be the night feature match tomorrow in australia and i think she's really up for it because i feel like the pressure

is off her on this one. the pressure is all on coco gauff, remember coco gauff is a finalist from the french open last year. she's a little bit younger, but she sort of had a little bit a lot more consistency out there on the tour. but she's not going to underestimate taking on emma raducanu. and i think the conditions here seem to suit emma. i think she was moving well in that first round match. i think she'll have a lift from getting through the first round and she can hopefully play with a lot of freedom going up against coco gauff. but it's going to be blockbuster. and that is all the sport for us for now. we'll see you soon.

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 center 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 whistlestop 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 set 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! i can feel you! that's so weird. you're tickling me. i am! 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! laughs that is really incredible. you could drop them on your hand and feel...oh! 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. ooh, my fingers are doublejointed. we've forgotten to do thejenga. this is much more fun, actually. oh, we have. let's move this out the way and play the game. yeah, ok. i've got to fix this. you're not doing it right. here we go. 0h...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. oh, no! laughs i'm going to prod you for that! 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. in amongst all of the screens and the cars and all the other weird stuff here at ces, there are plenty of home appliances too. some of them can roam around by themselves these days. but have you ever wondered how they find their way about? well, many of the modern ones use something called simultaneous location and mapping. for short, slam. modern domestic and industrial robots are notjust bump and go, you know. they need to build up 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.

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. they 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 in to 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. paul: 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. 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 the app 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 lights 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 wasjust 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. now, this is the shortcut of click from ces. if you'd like to see more from this place, then you can check out the full—length version, which is waiting for

you right now on iplayer. so, that's it from vegas. well, should we do some more next week? yeah, why don't we? why not? thanks for watching. see you then. this is bbc news, we will have the headlines and all the main news stories for you at the top of the hours straight after this programme. this week on the travel show... mastering the tile with a style in morocco. you're doing a greatjob! am i doing a greatjob?

well, i tried. ok, down the hatch. and we're talking tortoise on the coast of senegal. why is he called bill, can i ask? because he arrived the month where bill clinton was elected. so you are named after a president! hello, and welcome to morocco and the historic city that's sometimes known as the country's cultural capital, fez. from its medinas and mosques to its madrassas, fez is steeped in cultural heritage —

so much so that the medina of fez is listed as a world heritage site. mind—blowing! absolutely incredible. this is the attarine madrasa. it goes back to the 14th century, and it is perhaps the best example of what they call zellij. zellij is a style of mosaic tile work made from individually hand—chiselled pieces that is found all across morocco, as well as parts of tunisia, algeria and southern spain. the detail — tiny, tiny detail. the art form dates back over 1,000 years, but the more intricate and colourful designs, which have become synonymous with moroccan architecture, were developed in the 14th century.

despite its mixed origins and geographical spread, experts like fouad believe that zellij is a vital part of his country's history and culture.

authorities here have long wanted to formalise zellij�*s moroccan connection. it's not uncommon for countries to do this by gaining un—recognised intangible cultural heritage status. for example, the french recently achieved this with the humble baguette, as have jamaica with reggae music. but in the case of zellij, morocco went a stage further and insisted on having it patented. it's part of a drive to protect the country's assets from cultural appropriation and commercialisation. i travelled to a traditional workshop just outside the medina to find out just what goes in to this ancient process. how many of these do you think he does, every... every day? yeah. so, every day, it depends if, for example... he can make up to

1,000 pieces a day. has he ever banged his fingers? they chat no, never. never? sayyid's craft skills were learnt as a boy — and some zellij producers are worried that these techniques will not be passed down to future generations. and that's partly because pay and working conditions are not as attractive as in other industries. sayyid earns around 12 euros a day. so, as you've seen, he's doing this by hand as well. yeah, look at that. nothing else. wow — and, again, this is exactly the same way they've been doing this apprenticeships can take up to a decade. and for most people, it's a lifelong dedication. so we do have our artisans who work as a couple, ok? the first one who is the one responsible of cutting the tile, as you're seeing here, with this specific type of stencil, ok? you just take the shape of it, the design of it.

he starts cutting it one by one, piece by piece, with a sharp hammer. i don't know who i think i am, but i'm going to have a go at trying to create a shape from this. and apparently you have to sit down exactly the way this guy was sitting down before. so here we go. it can take six months just to achieve the correct sitting position, let alone try to cut and shape the tiles. you're doing a greatjob! am i doing a greatjob? oh, there we go. well, i tried. after assembling all the pieces, we'll bring them all the way to another artisan who is responsible of putting the pieces next to each other. every single piece, it's like a type of puzzle. so what does othmane think

about morocco's successful claim of ownership of zellij? morocco is very well known when it comes to its culture and traditions, and the heritage, the culture of the heritage that we have, is typically moroccan, and those artisans that we're talking about are typically moroccan as well. as for the future, it's hoped that the craft — with its new protected status — will survive, thrive, and proudly proclaim "made in morocco". now, if you're thinking of taking a trip to morocco in 2023, finally this week, we're off to west africa on the trail of one nature lover who's celebrating 30 years of protecting some of the region's most

vulnerable wildlife. some call him the father of the turtles — and his work may have already rescued one species of terrapin from extinction. we sent emeline nsingi nkosi to meet him close to his home in senegal. about three hours' journey south, away from the traffic and chaos of senegal�*s capital, the dust and aridity begins to give way to greenery. mangroves and, crucially, seagrass start appearing here along the coastline. and the wildlife becomes more abundant and precious for all number of reasons. turtles, tortoises, and terrapins have been a big part of west african traditions and symbolisms. and in some tribes, they are revered as being a good luck charm, a good omen — which is why it's so surprising that their numbers have been going down so much. all five species of sea turtles that nest on these beaches are endangered, thanks to fishing activities and pollution. but this man's made it his

mission to save them. i'm going to put a tag, and after that, we are going to let it go. oh, let me remove that little sand for you. now you can breathe clearly! why the tagging, i mean, why is it done? with that, we can track the migratory pattern for the animals. when we know that, we are going to be more accurate in the strategy we need to implement in order to save this species. because the more you know about the species, the more you are going to be able to save them. ifeel like i need to hold my breath. oh, breathe in! does that hurt or is thatjust like getting your ears pierced? yeah, it's going to hurt, but it's going to... save your life at the same time? yeah. tomas is about to celebrate 30 years of working with turtles in senegal. his work has brought him awards and recognitions from around the world. he's so gentle with it.

i mean, you can see that these turtles actually are his babies. that's quite an impressive sight. i've never seen it, and i'm sure all of these people haven't either. everyone literallyjust ran down to the beach to see this release. on the outskirts of dakar, in the back yard of his dad's old farm, tomas has built this village of the tortoises. it's popular with tourists and school groups, but it's also a hospitalfor sick and injured turtles. you see the remains of the place where they dig or they draw a hole in order to put a rope to attach the turtle. wait, why was a rope attached to the turtle? yeah, because when you have them in captivity and you don't want them to dig in the middle of your lawn... oh, no! ..you want to have like a rope in order to control the animals. but now, tomas is taking me to see

the head honcho here. this is bill. so does bill know you? no... would you say that he...? usually, turtles are not like dogs. they don't celebrate you like my dog celebrates me when i come back at home. and that is frustrating, because i spend more time and more energy serving them than my dog. that is the reality. he's between 70—80 years old, and he and tomas go way back. why is he called bill, can i ask? because he arrived the month where bill clinton was elected. so you are named after a president. i hope you feel the weight of your name. yeah. you don't hear much about terrapins and tortoises, but tomas has dedicated his life trying to correct that and make sure that they don't go extinct. and you know what? i've got a feeling that he just might win.

hello there. cold weather will hang around for another few days just yet, and i think there's a growing risk of seeing some disruption into wednesday. on the satellite picture, lots of showers starting to swing their way eastwards, and many of these are of snow. now we've got a band of snow moving across scotland and across northern ireland. and then, as we head into the first part of wednesday morning, i think showers become much more frequent across wales and western england, particularly parts of the southwest. now over the hills, we could see accumulations of around 5—15cm by the time we get through the day on wednesday. and so, for these areas, there is a risk of seeing some disruption. there'll be a widespread frost and, where we've seen seepage off the fields, particularly across the south, we'll have dangerous conditions out on the roads, in terms of ice. and then, we've got those snow showers that will continue to pack in. now, plenty of sunshine around — on the face of it, temperatures a little bit higher than we had on tuesday. however, we'll have really quite

brisk winds, and i think that will make it feel bitter if you're out and about.

welcome to newsday. reporting live from singapore, i'm karishma vaswani. the headlines... china's population falls for the first time in more than six decades. we look at the impact that is having. belgian police say a key suspect in a corruption scandal at the european parliament has cut a deal with investigators. as the us and uk renew their commitment to helping ukraine, troops on the front line tell the bbc they desperately need western tanks to make progress. both president biden and prime minister sunak have committed to standing with ukraine for as long as it takes, and our teams are in lockstep as we co—ordinate our efforts both with one another, and also with our many

allies and partners. and could one of britain's richest men become the new
