sport, and for a full round up from the bbc sport centre, here's holly. england's cricketers have had a great morning in port elizabeth, on day three of the third test against south africa — but their progress has been held up by rain. dom bess took two wickets in the first half an hour — both caught by ollie pope, after his century yesterday — and just before lunch bess took his tally to five wickets in the innings, leaving south africa on 113—5 — that's a lead of 386 for england — but there's been no play since.

watford, who are fourth from bottom, take on eighth placed tottenham. watford have won their last three premier league matches. ashleigh barty, has got off to a good start, just a few days before the australian open begins. the world number one has won the adelaide international after beating her opponent dayana yastremska 6—2, 7—5. she said she couldn't wait to get going in melbourne on monday. the eyes of a nation will be on barty at the first grand slam of the year — she's aiming to become the first home winner of the women's singles title since chris o'neil in 1978. it's a retrun that many ufc fans are eagerly waiting for, and this weekend, las vegas will be full of them. that's becasue after 15 months out of the, conor mcgregor is back. despite there being no title on the line, the bout is set to break

pay—per—view figures. the irishman is stepping up to welterweight making it far from is stepping up to welterweight making it farfrom clean is stepping up to welterweight making it far from clean cut for the bookies favourite. we haven't really had a big discussion of what the exact fight strategy is in terms of taking him down in the first round, big punches, it is going to be a master class, he will be at have a lot of pressure from the get go and it will not let up. it was a great late—night comeback for stuart bingham. the 2015 champion made a stunning recovery at the masters snooker, coming from 4—1 down to beat kyren wilson 6—4 and reach the semi—finals. the match finished at 10 past midnight, having started at 7 o'clock in the evening. bingham will face david gilbert this afternoon, after shaun murphy takes on ali carter. you can get all the latest sports news at our website — that's bbc.com/sport. but from me and the rest

of the sport today team, goodbye. this week, we are staring into the future. we are self—driving around china. that is a bit creepy. and we are flexing our... that looks painful! not quite. give me the chime, i'm doing it! ca rs. they are always one of the biggest draws at tech shows and last week's ces was no exception — there were plenty of innovations inside the vehicles and out. say you wanted to rent this beauty for the weekend, and when you returned it there were a few dings in the body —

how do you conclusively prove that you didn't do them? what you need are a pair of these. these are check scanners. a french innovation that can inspect a car for damage in the time it takes to drive through them. there are ten cameras on each side and machine learning has been trained to spot dents and scratches that can be compared to those that were there when you picked the car up. it is also for manufacturers to spot any imperfections in new cars, and in a world where we are buying more and more things online at a distance, these could be useful for producing condition reports for second hand car options. but much of the car innovation on display at ces was of the self—driving range. after all, whoever steals a march in this area will be in the best position to tap into the billions that this sector offers. it is taking longer to perfect them than some realised —

it is all about data from testing, testing, and more testing. which is why, although private companies are at the vanguard, behind—the—scenes, the big nations are facing off to provide the most favourable regulations. the big rivals here, you probably guessed it... the us and china. the us was initially quicker to grant licenses to companies, but its superpower rival has also woken up with big deregulation plans of its own. the huge corporations on the front line, alibaba, google, ford, and more are now battling to capitalise, to hone their algorithms and create the first truly autonomous road vehicle. stephen beckett visited one of the global leaders in autonomous vehicles to find out more.

this is the south of china. about 75 miles upriver from hong kong. it is one of china's biggest and most developed cities. home to around a0 million people, and now it is one of a handful of cities in china running large—scale trails of self—driving cars on public street. this is pony ai. you may not have heard of them but here because have site in the area around their head office. —— heartheircars —— hear their cars have become a common sight. over the last year they have been running an autonomous taxi service in the city. at the moment, the trial is only open to selected family and friends of pony ai employees. pretty good deal though if you can get access, because it is completely free. with just a few taps on an app, an autonomous taxi will come straight to you. so this is operating all around the district, mainly the urban bit. so we have quite a lot

of choice of where we can go. where shall we go? that is a bit creepy. the driver has got his hands in a kind of ready—to—go position. there is some chap driving on the wrong side of the road just there. the car did slow down a little bit. braking...but seem to have got through that one unscathed. some of these things just don't happen in other places in the world. if you are building a self driving car in the us, it might not know what to do if it sees someone driving on the wrong side of the road for the first time. but making sure vehicles like these are safe enough to roam free without a back—up operator is the next big challenge for autonomous car companies around the world. this man leads the engineering operation here at pony, so it's hisjob to make this a reality. sometimes in each different city,

the traffic and driving behaviours are totally different than, say, in the us — usually they obey the traffic a lot more and attempt to lane change, but in china, the driving behaviour is more aggressive so it is sometimes unpredictable, especially for cyclists, so you have to put everything into consideration. it's something they keep telling me here, chinese data is richer than data in the us. right now, most self—driving car companies are focused on getting their vehicles to work in their home countries, but once that is figured out the rest of the world is next. and it could be that cars trained on unpredictable chinese roads will stand a better chance in places like india and africa. pony al was founded in 2016, it is only three years old. we are almost as good as the

autonomous driving car companies in the us. because the roads in america are a bit more predictable than they are here in china, do you think they will get to the self—driving dream first because the problem is a bit easier in america? actually, we think differently, because in china it is more of a challenge. i would say we drive one kilometre on chinese public roads — it is like ten times more value than driving one kilometre in united states. that is why we can improve faster. this screen here is designed to give the passenger an idea of what the car itself can see. that car, this car in front of us, is represented on here as a different coloured lock. —— coloured block. oh, you see, that was an interesting situation. these guys are pulling up, this car is coming up on our right,

but the car managed to handle it stopping — the driver didn't have to step in. we want to go here, i think that is why it is confused. this is a pretty confusing situation, even for a human. you can see why it is confused because it wants to go in here, and there is a lane of traffic there, so i think that is probably what i would have done as well. i am pretty impressed, it handled a few tricky situations, we had a guy on the other side of the road, but it didn't do anything that felt dangerous which i think is the main thing. it wasn't exactly like a human driver, still some of the way it moves, the decisions are made, probably would feel a bit unusual to you if you were used to a human driver, but it is on the way. when it comes to technologies that are consumer facing, they don't have any obvious political impact or anything to do with content, the chinese government is very relaxed about letting entrepreneurs innovate first, seeing what happens

and maybe regulating later. and that often is the opposite sequence to what happens in the uk or the us, where governments will get ahead of potential problems — for example, self—driving cars — and permit regulations first and the industry follows. the reality is that for a long time, china was lagging behind in autonomous technology, but as we know, when china makes a decision to do something, as it has here, things can happen very quickly. at the southern end of the las vegas strip is the mandalay bay hotel. on october ist, 2017 this was the scene of a tragedy. the us‘s deadliest ever mass shooting. a gunman in one of the rooms opened fire on a crowd of concert—goers across the road.

he killed 58 people and injured more than 400. the incident sparked a review of security across the city, but now it is being taken further. richard taylor has been looking at whether technology can stop would—be perpetrators in their tracks. here's the dilemma. how do you keep the world's entertainment capital safe without turning it into a party pooping security fortress? patriot one believes it has the answer, using unobtrusive sensors which generate information feeds which can be assessed to see if someone is carrying a weapon. this vegas casino resort is now rolling out the technology, which has been in testing for the past two years. we have got various bits of hardware here... the system can be placed in a building entrance

or a turnstile, and unlike a metal detector it creates an invisible fence. you wouldn't even know it was there. ifiam you wouldn't even know it was there. if i am carrying a concealed weapon on my person, or worse still intent on my person, or worse still intent on an act of violence, the system as it is deployed here invisibly in these planters, can kick in, the ai making a determination of whether or not this is benign and alerting the security authorities to take the releva nt security authorities to take the relevant action. the pat scan device works on several levels. the one thing emits residents frequency patterns that identify the shape of an object. another sensor creates a magnetic field and detects disturbances as an object passes through. but the real smarts lie in the ai algorithms. within seconds, they assess the data against its own database to figure out if weapons are being hidden.

with daily shootings in the us and a knife crime epidemic in the uk, the allure of a system to keep us safe is certainly set up. we want to be in public schools, hotels, university campuses. we are now in the business of rolling it out stopping the uk market will be extremely important to us, particularly when it comes to knives because of the knife crime crisis, and in fact knives are being used by terrorist groups for mass attacks. but ground—breaking as the tech is, it is largely unproven. how accurate is your system? because when it comes to ai, the machine is only as smart as the data that you are feeding it. we have been out for a long time with tremendous partners who have allowed us to get a lot of data

here stop at the university of north dakota has been hugely supportive in that way. we have built sufficiently large data holdings that we now have confidence in the accuracy of our systems. enough confidence that we are now into our first commercial deployment. our early adopters also understand that the systems get better and better the more data is fed in, so they are equally allowing us to ingest data for training the system. the system isn't100% accurate or foolproof, and an assailant may well get into the premises another way entirely or the weapon may be hidden in something different like a metal box. an additional security layer is needed. if i'm openly brandishing a weapon, that is where the eyes of the system kick in, a so—called machine vision where a security camera can make an assessment based on what is in my hand, based on what is in its database and if it finds it is likely to be a weapon, then it will trigger a relevant alert. the idea of augmenting human eyes with this method of computer vision is catching on globally. a number of outfits promising enhanced security for a person

and object detection. understandably, that leaves many people uneasy. we are very conscious of the fact that people don't want to live in a mass surveillance society but there are very different ways in which we collect data. we don't capture any personal information or store or distribute personal information. we are looking for objects — people are of no interest to us unless they are carrying a threat object. what our ai has been trained to recognise is the difference. it is not making any determination on people or capturing personal information or body image. that puts us on the right side of that line between too much surveillance and not enough security. hello, and welcome to the week in technology. it was the week that us president donald trump clashed with apple over the tech giant's data encryption rules. apple refuses to unlock iphones in relation

to criminal investigation citing privacy concerns. microsoft ends its support for windows 7 after ten years, meaning users will no longer receive security updates. the uk's national cyber security centre is recommending windows 7 users replace their unsupported devices as soon as they can. london's heathrow airport is following a new anti—drone system that will allow it to pinpoint unauthorised aircraft and their pilots. the move comes as airports are looking to increasingly prevent drone disruption following a temporary closure at gatwick in 2018. tesla cars are being able to talk to pedestrians in a baffling british accent. car: well, don'tjust stand there staring, hop in! in true knightrider fashion, tesla ceo elon musk tweeted a video of a car speaking to passers—by. the feature will be used to talk to other road users and pedestrians as well as provide a flatulence function. what a time to be alive. and finally, if you've ever wondered whether your pet pooch would enjoy a podcast,

spotify has introduced a new range of personalised playlist for pets. pet playlist is a new experience spotify users can get a curated playlist for their pets based on their tastes and character attributes. pet sounds anybody? there isjust so much to see here that i've been getting my hands, ears, eyes, nose and mouth onto wearables. first up, no this is not a pair of goggles, it is the prototype of an air purifying mask. the finished product will look like this. with claims it is 50 times more effective than the market leading cycling mask, the ao air uses nanotechnology and air pressure to filter out harmful particulate matter. once described as a multistage filtration system, it provides

the process of our being sucked in. that air will then be cleaned and pushed out the front, creating your own environment of pure, clean air. currently, the prototype is a lot less comfortable than the finished version and this is a size too large and i need a smaller one. ifeel like my nose is being held and i probably sound like that. it will take some getting used to but it is actually adjusting according to my respiration rate, so right now the fan speed is at 16%. i can make the fan go up more if i want more air to be pumped. i feel like i'm at the dentist. imagine what i could do — i certainly couldn't run like this but maybe ride a bike. i don't know. it is notjust about the device but also about collecting data, localised air quality data and also respiratory information. there are some plans to use that for some health tech in the future, particularly in regards to meditation. it has five hours battery life and in time, the device will be miniaturised. despite the fact that i thought i looked completely

and utterly ridiculous, it has actually made it to the catwalk, featuring in new york and seoul fashion weeks. back on the show floor, there was also the sixth finger. sixto is a device for people who have limited mobility in one hand, so could be due to a stroke or something like that. the way it works is that you position the bad hand where it needs to grab something and this joystick, which will be held in the good hand, is used to be able to close the device so you can actually pick something up. one of the other benefits of this is that it actually encourages somebody to use a hand which isn't functioning properly rather than holding their arm in a position where it is likely to get stiffer. in the depths of one slightly more secret meeting spot, came this view into the future. this is a contact lens that provides augmented reality. apparently, it fits like any other scleral or semipermeable contact lens.

this could be used for translation where the words would come up in front of when you are having a conversation with someone. the idea is that this is all about invisible computing, that something like this should be less intrusive than having your phone in front of you. wow! that is incredible! in a way, the fact that there is little enough information for it to not be totally distracting makes it better. i think if they put too much up it would become too overwhelming. while i wasn't allowed to wear it, just holding it up, i could see some simple stats right before my eyes, which having been sceptical in advance, i was pretty blown away by. how is it possible to fit all of this into the lens? we had to build our own wireless protocol between the contact lens and another wearable accessory because we had to manage power and data and size of chip and that accessory connects to your mobile phone or the cloud, to access additional computing

resources and information. it is very comfortable, fits to your eye and corrects your vision when you wear it. if you have a prescription, we build up a script into the lens. heart rate data, speed, and even with your eyes shut, you would able to see this because it is lit up and obviously the lens is sitting beneath your eyelid. it feels seriously a sci—fi. and there you have it, what to wear, to see and feel in the future. there, never taken that photo before. the thing about coming to las vegas straight after christmas is you eat lots of food followed by lots more food. and chris fox has decided that he is going to use technology to help knock him back into shape.

this is what he has found. these three new apps are designed to help with your fitness goals using image recognition, machine learning and motion sensors. but are any of these apps advanced enough to replace a personal trainer? i've come to the gym to find out. first up, is vay sports which uses image recognition and a selfie camera to make sure you're doing the exercises properly. you choose a trainer and put the phone a few metres away and follow the instructions in your headphones. great, i can see you. here we go with push—ups today. get into the starting position so i can se you at all times. based on what the camera sees, the app gives you feedback to correct your form. you call that a rep, your hips are a bit too high up. it also counts how many reps you do properly so you can track your progress. nice work. how are the back of the arms feeling? the app only works with body weight exercise at the moment so to move on to weight training, i'm trying gymfitty, a virtual trainer you can talk to.

i'm done. rest for two minutes. how many reps did you do? 10. well done! let's do another set. the app creates a bespoke work—out tailored to your goals and it remembers how well you did last time so you don't have to log your work—out or write anything down. i want you to add another five kilograms to each side of the bar. ping me when you are done. to relax, i'm finishing off with some yoga. this is yoganotch, which uses motion tracking sensors to detect my position and correct my form which fair warning is going to be terrible. not quite. give me the chime, i'm doing it. i got a chime, i did it right. i'm not sure whether setting up these senses every time will take some of the zen out of yoga although the company says it is more accurate than using image recognition. oh, come on. these apps certainly add a layer of interactivity to a work—out

but can they match the kind of encouragement you get from a human personal trainer? you can train just as effectively bare in mind that it is able to process huge amounts of information very specific to you and it's with you all the time. and there you have it, a downward facing dog from a forward facing fox. was that cheesy? i know, we are in vegas. although next week, we won't be. we're going to los angeles. and with oscar season just around the corner, for us, that means we start our very special look behind the scenes at the best, most innovative work in visual effects that's up for awards this year. i cannot wait. please do join us then, in the meantime, you can find us all across social media, youtube, instagram, facebook and twitter at bbc click. thanks for watching and we will see you in la.

hello there. we have been used to mild wet and windy weather, so things this weekend are going to be very different. instead of low pressure, we actually have an area of high pressure building in, settling things down. that means for most of us this weekend it is going to be dry. the sunshine will be out, the winds could be strong, but it will be cold. we have already had a frost this morning. there will be another one this morning as well. this weather watcher picture gives a flavour of how it has been. down to —3 or so. there have also been some showers of a wintry flavour in scotland already. those showers will start to become fewer through the rest of the day as the winds ease a bit and it should then turn dry for northern ireland and north—west england.

more cloud coming in here spilling into wales in the south—west, otherwise blue skies and sunshine and lighter winds. maximum temperature around six to eight degrees. that is near normal for this time of year. clear skies, light winds and showers fading away from scotland, we are going to get a frost developing widely, and even in some towns and cities temperatures could be down to —2 or —3. the exception could be the highlands and islands of scotland. here we have a milder wind coming in from the atlantic around the top of the area of high pressure. follow the lines all around and into the southern part of the north sea and there could be some showers flirting with some of these coastal areas early in the morning. apart from that, and the cloud that is coming in and the stronger wind into the north—west of scotland, we have got light winds, plenty of blue skies, a cold crisp winter's day tomorrow. and again, temperatures typically seven or eight degrees. it will be milder where it is cloudier towards the highlands and islands. that milder atlantic air will eventually push its way south through next week as the high pressure gets squeezed southwards,

but as we move into monday, quite a contrast across the uk. milder where it is cloudier and breezier further north, colder further south where it is clearer. there may be some mist and fog around in the morning, slowly lifting. then the sunshine develops once again. more of a breeze, though, for northern ireland, scotland, bringing in some more cloud, especially western scotland. pretty mild, though, for the north—east of scotland. further south, after a frosty start, again seven or eight degrees. into next week, you will notice, well, where does the sun go? it looks like is going to cloud over more. there could be some mist and fog patches, but with the cloud around it won't be as cold at night.

good afternoon. the five mps who want to replace jeremy corbyn as labour leader have been taking questions from party members in liverpool. it's the first of a series of events around the country which will culminate in a new leader being selected at
