good evening, this is your update from the bbc sport centre. it was a chance for manchester united to leapfrog their rivals manchester city and close the gap at the top with a win over crystal palace. but a stunning late equaliser put paid to that after united took the lead but had to settle for a 1—1 draw. nick parrott reports. manchester united have been building a momentum that has seen them become title contenders. but if they're to become champions for the first time since sir alex ferguson left, they need to win at places like selhurst park. they lost there at the end of last season before erik ten hag took charge. since then, the dutchman has worked some magic. david de gea showed he can still be a saviour.

odsonne edouard couldn't believe he hadn't put crystal palace ahead, and captain bruno fernandes continued to lead his united side by example, scoring in successive games. a second goal would have secured the win, but for the first time in eight matches, marcus rashford couldn't score. sunday's trip to league leaders arsenal will be trickier after casemiro�*s booking means he'll be suspended. and palace rubbed salt into those wounds in time added on — michael olisa, equalising to send the home fans delirious and united home furious. nick parrott, bbc news. leeds hammered cardiff city of the championship in their fa cup third round replay and what a goal to get them off the mark. wilfried gnonto scissor—kicked a stunning volley in off the crossbar after just 26 seconds, the first of two goals for the 21—year—old italian, a real contenderfor one of the best in the competition. rodrigo and patrick bamford got in on the act in the 5—2 victory,

bamford with two goals. continuing his fine run of form, callum robinson got two consolation goals for cardiff. now in the scottish premiership, celtic maintained their nine point lead at the top with a 4—0 win against st mirren. meanwhile, rangers were made to work for their 3—2 win at kilmarnock. ryan kent put them 2—1 up after they fell behind early on. and kilmarnock were reduced to ten men before alfredo morelos got his second of the game as michael beale�*s side ran out 3—2 winners. elsewhere, hearts beat aberdeen 5—0. britain's cameron norrie has reached the third round of the australian open after a late night win over constant lestienne. norrie completed a 6—3, 3—6, 7—6, 6—3 victory over the french world number 55, who was making his grand slam main draw debut. it was a roller—coaster match that lasted more than three hours, finishing its 1.30am in the morning in melbourne. the british number one will playjiri lehecka of the czech republic next.

emma raducanu is out of the tournament, though, losing a fascinating battle in the second round to seventh seed coco gauff in melbourne. gauff controlled the opening set, power helping her take that 6—3. there were fears raducanu was hampered by an injury but she burst into life and forced the second set to a tie—break. the final rally epitomised the match, a battle between two of the best young players on the planet, but gauff edged it to knock raducanu out. it means the briton hasn't reached the third round of a grand slam since her stunning 2021 us open win. i still think, you know, i didn't necessarily play my best today and although, like, the second set i had chances and was pushing it was still i felt like i could have done better myself but props to her, she is a great, great opponent and a great athlete. the defending australian open champion rafael nadal says he's mentally destroyed after losing to world number 65 mackenzie mcdonald in the second round. the 36—year—old suffered

what appeared to be a hip injury in the second set, crouching down visibly in pain before seeking medical treatment. his wife was in tears. nadal showed his usual fight after but was still in discomfort, losing in straight sets. his earliest exit at the australian open in seven years. now, to what's been described as the biggest corruption scandal in the history of snooker. ten chinese players suspended as part of an ongoing match fixing investigation have all been charged by the integrity unit of the wpbsa, the sports world governing body. the allegations ranged from fixing matches, approaching players to cheat, and betting on snooker with high profile players such as masters champion yan bingtao among those named in the investigation. we have to deliver world class live entertainment that has to be pure live sport competed to the highest level. and to do that, we must know the sport is clean. so the damage for me is short term. we have to take the

short term pain now, we have to clear this issue up and we have to move on. we will move on. wales�* male and female senior football players will be paid the same for representing their country after the men's team agreed to a 25% pay cut. the deal agreed with the football association of wales will come into effect immediately and will enable them to give the women's team a 25% increase, meaning parity for representing the nation. and dame laura kenny has announced she is expecting her second child. the five—time olympic cycling champion announced last year that she suffered a miscarriage in 2021 and then had a fallopian tube removed injanuary last year due to an ectopic pregnancy. she came back from that to win gold in the scratch race at last summer's commonwealth games in birmingham, along with a bronze in the team pursuit. in today's post on social media, she said that the heartbreak will never go away, but she's now hopeful of things ending happily this time. let's finish with some cricket news. south africa's second highest test run scorer, hashim amla, has retired at the age of 39.

amla scored 9,282 runs, second only to jacques kallis. and no—one has scored more than his 27 one day centuries for south africa. amla's 311 not out against england at the oval in 2012 remains the highest test score by a south african. that's it from us, keep up to date with all the latest on the bbc sport website. we will 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 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. 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. we call it the positive protection, and that is just to protect their traditional knowledge or, in this case, cultural 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 for hundreds of years. 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". 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. tomas started as a teenager rescuing african spurred tortoises — the second—biggest species in the world.

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. so you saw bill in the zoo when you were a teenager? a teenager, yeah. wow. because i spent a lot of time going to the dakar zoo. in fact, that was my favourite place to go. 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.

welcome to newsday. reporting live from singapore, i'm karishma vaswani. the headlines... ukraine's interior minister is killed in a helicopter crash in kyiv. it came down close to a children's nursery. 1a people have died, including a child. translation: we ran - into the street and turning. there were bodies and debris lying around. there was smoke, blood and clothes — and mothers were running. after her acquittal on tax evasion charges, philippine journalist and nobel peace prize winner maria ressa tells me about what she calls the weaponisation of the law against her. and you know, it went down to these three things — facts, truth, and justice.

that is who won today. also coming up in this hour of newsday...
