and local favourite — to qualify quickest for the quarterfinals, and what's more sett better than the snowboarders. edelmann died been nervous like that in about six years. it wasn't even my skating. everyone back home is waiting to see me skating, i was so nervous. i thought maybe i'm not going to be able to do this because i was so nervous, but actually it was fine. and just glad i got to do it in front of everyone against. christie faring better there, than britain's snowboarders did this morning. all three men failed to qualify for the slopestyle final. now back home, and in the six nations, a mouthwatering contest at twickenham, where england take on wales. england, remember, are bidding to win the title three years in a row — they domainated against italy last week, but wales were mightily impressive too, in their win against scotland. it's a big occasion for everyone involved. but, for us, it's the next game. the next game on ourjourney, the next game to develop, improve,

and focus on performance. i tell you what, if we get our performance right, we'll get a result. you're not playing the venue, you're playing the occasion, the game and the guys involved on the park. 8000 fans are going to make the occasion, but past results and performances mean very little. the first game of the day is in dublin where ireland ta ke the day is in dublin where ireland take on italy. skipper rory best said that moment boosted the team all week. it's just said that moment boosted the team all week. it'sjust amazing how the kick of the bowl and 82 and a half minute or whatever it was of rugby can change the context of how you feel and the mood. can change the context of how you feeland the mood. like i can change the context of how you feel and the mood. like i say, getting back home to the six nations is a big thing for us. the big match in the premier league today is the north london derby — tottenham against arsenal at wembley.

they just kicked off theyjust kicked off a couple of minutes ago and there have still been no goals. celtic park 2—0 up against partick thistle after 12 minutes with james forrest with both goals. in cricket, australia have cruised to a seven wicket win against england. this spectacular throw from david warner after both openers had gone with only 11 runs on the board, what a true that was. australia reaching their target in the end with 33 balls to spare. england now face back—to—back matches with new zealand to decide the other finalists. matches with new zealand to decide the otherfinalists. next, like. this week, uber the top. old deckard meets new...who? and smile, we're in dubai. this is how a self driving

cars sees the world. lidar sensors feed the car with a continuous 360 degree view of its surrounding, along with crucial depth information. it is the key technology for a successful autonomous drive. and this week in the us, a mighty court case has begun which may take this key away from uber, stalling its progress towards the self driving revolution. it all revolves around this man, antony lewandowski, who left

google's autonomous spin—off waymo and joined uber a couple of years ago. uber continues to look to the future of transportation, which in just a few years might look very different to the way it looks now. dan simmons has been looking up. even self—driving cabs will get stuck in jams, so this is uber‘s vision. when you're tight for time, go by air. it's ambitious and so is the timescale. our goals is by 2022 to launch our first demonstrator flights in dallas and los angeles, to show that as a proof of concept that can work, and then work to scale by 2023 and 2025, so we're providing commercial flights to a lot of our riders,

giving them a new way to travel. one of uber‘s partners, bell helicopters, has shown off its design for a four seater cabin, which could include a pilot. here's their 360 view with the alternative set up, four seats, four passengers. the aircraft, like our cars, would navigate automatically. it's electric with a range of about 60 miles, they say. we've seen other designs for air taxis of late, including chinese firm ehang's184, which recently shuttled actual people in this autopiloted drone. and this air cab by german firm, volocopter, which uses 18 motors and nine separate battery packs — just in case. while nasa and the faa are working on new air traffic control systems

for this type of craft in the uuited states, it's the fa that will have to be convinced self—piloting electic air cabs are safe. we will ask the applicants to come forward with engineering proposals and what tests they propose to do, so that we can assure that if there's a fire or a short or if something goes wrong during a flight, that somebody can safely land and get away from that aircraft before it does damage to people on the aircraft, or on the ground, for that matter. so will it work? here's uber‘s case study. we've landed in la, traffic‘s a nightmare and a taxi would take us 18 minutes, whereas the air trip to the sky port, plus a short transfer, is less than half an hour. and uber says it could end up costing about the same amount. 0k, there are many reasons why self flying taxis sound like a good idea, but when you're saving less than one

hour, uber‘s dream will need to run smoothly to deliver. apologies, mr simmons, very busy airspace right now. it's blade to blade up there. unfortunately, the weather's closing in, mr simmons. we're not quite sure we're going to be able to get you in tonight. really sorry, we're just cleaning out the cabin. you're two kilograms over, i'm afraid. might want to lose the penguin? we're just recharging your taxi at the moment, mr simmons, it'll be a while. at least that last one shouldn't be too much of a problem. uber have teamed up with ev specialists, charge point,

and are predicting a four minute charge up time. now, that would be special. sorry, you're running 17.5 seconds late and the pilot's had to cancel. please do book again via the app. but perhaps the most challenging part of this project is to get us, the public, comfortable with the idea of taking an air taxi. when we think about consumer adoption of new technologies, this is not a problem that's novel or unique to air travel. we saw this with elevators, when they first came out, and actually in order to get consumers comfortable with it, an elevator operator would remain in the elevator, even after it was made electronic, just to give consumers comfort. we're going to be doing the same with the driverless vehicles right now, as we have safety drivers staying in the car, explaining this sort of technology to riders, and the same will be true with our pilots.

we will be launching pilots who will serve not only as the operators of the flight, but as an ambassador to get riders comfortable with this new mode of transport, so soon enough they'll forget about its novelty and get back to their texting and making other use of their time during transit. just like the uber waymo court case over who owns the specialist tech that makes self—driving cars work, the creation of the flying cab will no doubt have its own dogfight in court. perhaps that's another reason why uber‘s keen to get in early. flying high isn't fun for everyone, though. 0oh. that was dan. now, the first place we are expecting these flying cabs to take to the air is of course the city of dubai, which always promises to foster and allow trials of new technologies.

although when we visited last month it soon became clear that flying taxis there too are still a few years off. but one big change that is being unveiled is not to do with aircraft but with its airports. kate russell has been looking at what's new in arrivals. dubai international is the world's busiest airport for international passengers. nearly 90 million people went through it in the last year and in the next couple it plans to expand annual capacity by one third again. this airport has two runways, it has three terminal buildings and four major concourses, but we have room for no more. so whatever growth we take from this point forward, it has to be done within the existing infrastructure. so it has decided if you can't get bigger you have the get smarter. i was invited for a peek inside its brand—new airport command and control centre, just before it becomes fully operational. this airport has been kitted out with the latest camera equipment to help staff predict the flow of passenger traffic. the technology is kind of cool.

what it does is it uses 3d cameras in the ceiling and looks for the outline of humans on the floor, moving around, and tracks them through the whole process. airport staff can get this information on smartphones and tablets, which helps them to direct the crowd, open new gates and even tell passengers where their baggage is. while all this data helps keep the airport moving, the amount being collected is also causing some issues. already there's 7 billion datapoints in there and we've yet to connect it up to everything. so we've got baggage data and passenger data but we've yet to put in things like energy consumption and water consumption. once we bring that together, we can really optimise the airport and make it more efficient and drive for even more passengers. so, what do you do when you need a data centre in a hurry? well, building one inside shipping containers is definitely one solution.

as dubai prepares to play host to a massive world expo in 2020, the airport had to do some quick thinking to be able to handle the extra 10 million passengers a month. this solution took just over 12 months to build. a traditional data centre, built out of bricks and concrete, would normally take about 2—3 years. next on the list of high—tech upgrades is face recognition, to clear immigration quickly, al to predict seasonal fluctuation in demand and a system to tell passengers when their baggage will hit the carousel. all great news if you're passing through the airport, but there is a solid business case for these upgrades too. the more passengers we can put through this site, the more profitable this airport will become and it's better for the city and the economy. so we're really working hard to make sure we maximise the use of the dubai international site. with aviation projected to contribute almost 40% of dubai's wealth in the next couple of years, this airport will continue to be a vital part of the economy. flying high isn't fun for everyone, though. 0h.

hello, world. acrophobia, or fear of heights, is one of the most common phobias, but this virtual reality therapy hopes to help. sweating again. chan here can confidently fly a plane, but when it comes to heights in general it's a different story. oh, no... oh, no, i've got to move! come back, come back. no, i can't do it. come back. i can't move while i'm out there. i couldn't go up a ladder. just couldn't go up a ladder. i couldn't go over high bridges. if i drove to wales i would go the long way, instead of going over the bridge.

ijust don't like open heights. but i canjump on an aeroplane and fly and aeroplane. that's a completely different environment, in my head anyway it is. welcome back. oh, god! oh, it's dark. so, how are you feeling? um. . .anxious, sweaty. nervous. even though you've been through the process of doing this before? yeah. you still feel the same level of anxiety, or is it dramatically reduced ? i'm way more confident. i've got much more confidence than when i did it the first time. i was on holiday with some friends. they were going on the rollercoasters and i talked about this vr thing we were doing and they said i should be able to go on the ride. so i watched my family and friends go round a couple more times and then thought, well, i can do this. if you look to your left, you'll see a basket of light balls. what i need you to do is throw the light balls down into the atrium. i think vr can treat pretty much any type of fear or phobia.

it might be a fear of a cat or spiders or dogs. what vr can enable you to do is relearn that actually you are safe in those situations you fear. the beauty of vr is in fact that disconnect. when you're there, you know you're not really in that environment and that enables you to do things you wouldn't normally do in the real world. but all the scientific data shows that learning you make in vr does transfer into the real world. in this programme you are going to try a series of tasks. earlier this month it was announced the uk's national health service has invested this idea of using virtual reality therapy to battle severe mental health issues are by putting sufferers in a virtual environment they would struggle within the real world. this immersive approach, plus the availability of virtual therapists, could more readily provide more therapy to more people at a lower cost. at the heart of a lot of health problems are difficulties with interacting with the world and with vr we can put people back in the situations that trouble them and coach them

in the best ways to think, feel and behave in those situations. we've got to test it and trial it and make sure things work, but the potential is enormous. hello and welcome to the week in tech. it was the week police in china donned special sunglasses to catch crooks using facial recognition tech. british mps went to washington to talk fake news with facebook, google and twitter. and virgin moneyjoined lloyds bank in banning customers from buying bitcoin with their credit cards. the cryptocurrency had another fall this week, falling to as low as $6000, before recovering. that's down from a high of almost $20,000 in december. it was also the week that spacex rocket, the falcon heavy, blasted into space. elon musk sent it off with his old cherry red sports car, a tesla roadster, a space suited mannequin, and a david bowie soundtrack on repeat.

however, it wasn't all good news for tesla, as the electric car company also posted its biggest ever quarterly cost — almost $700 million. it says it's addressing production issues with its model 3 car. and finally, a 14—year—old has created an app to help people with alzheimer's disease. it uses facial recognition technology to help people remember their loved ones. they can scroll through photos of friends and family and the app lets them know who the person is and how they're related to them. you can also take a picture of someone you don't recognise and the app will try to identify them. now, if you are a film fan, you will know that it is awards season, and over the next few weeks, we'll be chatting to some of the real heroes behind the movies nominated for the best visual effects 0scar. first up, blade runner 2049 — and spoiler alert, if you haven't seen the film, you might want to go and make a cup of tea for the next four minutes or so. still here? good.

well, if you have seen it, then you'll know that the character or rachael, from the original movie, makes a surprise appearance, looking exactly like she did in 1982. we found out how. i had yourjob once. i was good at it. things were simpler then. a lot of the work we do in visual effects is kind of very broad and very strong, think about the monsters screaming towards camera. this was the complete opposite, it was very subtle stuff. so it was all in the kind of micro details of the face. so the biggest challenge

is with the emotional performance and in this case, she was talking, so she was delivering lines. don't you love me? we did three shots from the original movie. that was kind of like a proof of concept that our digital rachael was good enough. we showed it to denis, the director, and the studio, and they couldn't really tell the difference and then — or you know, they had to struggle to see which one was digital. that's kind of when we knew we had it in the bag and that she was good enough to hold up on the big screen. we had sean young onset in budapest, so we scanned her and get another photographic reference of her as well. and ehat that allowed us to do was to fit a digital skull inside the digital model we had of her. when you age, obviously your soft tissue drops down with gravity and you get wrinkles and so on, but you skull doesn't change, so your skull is pretty much the same. what that allowed us to do was that we had a digital skull and we kind of built our 23—year—old sean young from 1982 around that skull, so the cheekbones,

the forehead, the chin, the nose, so on, we could kind of fit it around the digital skull, which was invaluable reference for us. and that kind of ensured that we had a physically correct model to sean young's real skull. we also captured the performance of a body double, so it's her body that's used in shots. so we had a lot of kind of treated data to work from. the good thing about the treated data is we can rotate around it on the computer, we can look at it from all angles. when it came down to doing the actual performance, it was all hand animated because basically, denis, the director, he wanted to basically direct a normal performance, like he would do onset with a regular actor. we can make a still image look very, very photo real and good, but getting that believable

animation, that's still the biggest challenge. i know you're here. great film, and next week, we'll be talking to the oscar—nominated visual effects supervisor of marvel‘s space epic, guardians of the galaxy volume 2. all i can say is, "i am groot". back in dubai, i'm really starting to see how determined this young country is to lead the world in everything smart. i have already seen the high—tech police force in action, met the robocops, and the drone unit that will watch over everything from the sky. now, i'm meeting the world's first minister for artificial

intelligence, and he's ambitious about what comes next. one of my favourite sayings from the tech industry is larry page of google said, "almost every time we do something crazy, we make progress. " do you find the same thing? many of the ideas that they come upo with, notjust silicon valley, even the top tech companies from around the world, whether from the uk or china, the common denominator with all of them is that they do not fear something that seems impossible. they come up with ideas that might seem crazy at first, but then the impact of these ideas will be truly global and phenomenal. so with that mentality and with the idea of let the brightest minds from around the world come, let them thrive here in the uae and let them create something for the rest of the world. how do you make sure that you bring all of the people of the uae along on thatjourney for digital change and innovation? the uae is very unique.

we have a very young population, that population can be retrained and repurposed in positions that will be created, i think, in the future. we understand the opportunity for us to lead the future. we launched an initiative in 2017 called the one million arab coders initiative. we're teaching 1 million people how to code. this is the language of the future. i think making these coders into our special intelligence experts is going to be a difficult challenge, but it'll be something that's easier than training someone who does not have any understanding when it comes to the language of the future, which is coding. so think about what apple has done for the iphone and what google has done for search, that, hopefully, is going ot be what the uae is going to do for governance. dubai is a place not scared to adopt new ideas orfail trying, so it's throwing all of its might behind leading edge innovations. concepts that may look outlandish elsewhere are all welcome here. and the dubai future accelerators programme is what the government hopes will take these ideas from page to stage. the government can drive the vision of where dubai goes next, i guess more like a

company than a country. after all, the monarchy needs little in the way of democratic input. a majority of this can fail, but the moment you create one success story, the sky's the limit on where you can be. so as long as you have that kind of mindset — a ton of this will be a write—off — but once you have that success, the whole world will talk about it and you will become a platform. we believe regulations, or amending regulations, in favour of any innovation is a must. entrepreneurs struggle a lot to show their new technologies and whatever they work on, and to have those decision—making individuals and the government work hand in had with them to really disrupt, makes life — makes the growth process much, much faster. so dubai mayjust have the recipe to pull it off, an accommodating leadership and a lot of cash.

this may be the perfect place to fail and come back smiling, especially as the government is committing to make dubai the happiest city in the world, alongside the smartest. visiting the dubai smart office, i was suitably welcomed by farah... mrs kate from bbc click, your host is waiting for you. ..who took me to meet one of the leading technology champions in the country, and despite the reputation the country has on the outside, it made me very happy to discover she's a woman. the technology is not the end of ourjourney, it's only a means that will take us to improve people's lives and make them more happier. by having artificial intelligence agents embedded in our government services, by having robots like our receptionist, this is the future — but yet we keep challenging ourselves. what is next? whether all this works or not,

you can see dubai is dreaming big. this is a dynamic, modern city, built from the desert up. maybe its motto should be — if you don't try it, you don't succeed. that was kate in dubai, and that's it from us for this week. don't forget we live on twitter at bbc click, and we're also on facebook too. thank you very much for watching and we'll see you soon. hello. changeable weather this weekend.

rain today for most of us as it's less cold than yesterday but much colder tomorrow, so snow showers are back on the cards. here is the weekend of weather set out in detail. weather system at the moment with outbreaks of rain for england and wales, clearing for a time for scotland and northern ireland, tomorrow a colder day. yes, there will be some sunshine but also some snow showers. here's how it's looking going into the afternoon. some outbreaks of rain becoming confined later to parts of east anglia, south—east england. then dry for a time elsewhere but more rain coming back to northern ireland before the afternoon is done. a snapshot of the uk at apm, we will see some clearer weather in scotland which means there will be some sunshine at times, a scattering of showers out to the west but after some sunny spells but after sunny spells in northern ireland, it clouds over again and outbreaks of rain come back. some showers but a dryer picture for northern england, wales, western england and into east anglia. the south east has the thickest cloud after some early sunshine today. it's been a cold start across eastern areas, there will be a slow recovery today, elsewhere some into double figures

maybe as high as 12 degrees in south—west england. more rugby today, sunshine on the ground is just a tease. cloudy and damp at dublin and twickenham. this evening, it will get stronger and gales in places, this isn'tjust rain, some snow especially in the southern scotland and northern england, notjust on hills, even relatively low levels. some accumulation especially in the hills, and snow showers in the north—west, you will notice as temperatures dip close to freezing, that means a risk of ice going into the morning. tomorrow, a much colder day, changing the wind direction north—westerly. you see the land, there will be good spells sunshine with showers coming in from the north—west, going further south—east in the day,

and it will cold enough for sleet and snow or hail, away from windward coasts, and the temperatures down compared to today. it is going to feel much colder. further opportunities for rain and snow as we go through the week, the next snow could be monday night into tuesday morning. we will keep you updated on that. goodbye for now. good afternoon. 0xfam has rejected claims that it covered up an investigation which found some of its aid workers paid for sex in the aftermath of the haiti earthquake in 2011. 0xfam's chief executive said it had informed the charity commission, but admitted more could have been done to spell out the details of what happened. downing street says the government is reviewing its relationship with the charity in light of what it called "truly shocking" reports on the issue. angus crawford reports. it was an earthquake that devastated haiti, killing more than 200,000 people, affecting millions more.
