we are in the middle of a six day shutdown of racing because of an equine flu outbreak. five more meetings cancelled today. six cases have been identified at the stables of trainer donald mccain in cheshire. over 170 yards are in lockdown. racing won't resume until wednesday at the earliest. it potentially can be incredibly serious and the economic and equine health consequences of an uncontrolled spread of an infectious disease can be incredibly severe. we are doing everything we can to first of all control and limit any further spread, put in place surveillance measures and then plan around what we know and how we manage the situation. great britain's fed cup team face serbia in the europe africa

zone play—off final in bath later today. katie boulter and johanna konta won their singles rubbers against hungary to make it through to the final. the british team haven't lost at all this week. if they come through the final they will earn a place in april's world group 2 play—off, win that and they would then get promoted to the second tier of the world group. england's third and final test against the windies starts this afternoon in st lucia. they've already lost the series but will be looking to avoid a whitewash. former world indoor champion dwain chambers will aim to win the british 60 metres title today at the age of a0. he remains a controversial figure for some following a doping ban 15 years ago. chambers has only competed twice since officially retiring injuly 2017 — he last represented great britain in 2014.

the top two in birmingham will automatically be selected for next month's european indoors in glasgow, provided they meet the qualifying time. you can see how chambers does in his heat shortly — there's live coverage of the british indoor championships on the bbc sport website now. you can find more on all those stories on the bbc sport website. they have kicked off at craven cottage, gold is so far. i will be back with an update later. this week: extreme weather predictions. 0n the mend with vr. and... # slam it to the left if you're having a good time # shake it to the right if ya know that you feel fine. uh... the last four years have been

the hottest on record. the climate is changing. average global temperatures are rising. as we continue to release more c02 into the atmosphere, scientists are repeating their warning that humanity faces extremely difficult decisions about our future. if we choose to reduce the risks from a changing climate, that will require reducing our carbon dioxide emissions over the coming decades. the implications to that are fundamental transformations to society about how we generate our electricity, how we travel around, what diet we have. those are the difficult choices that, as a global community, we have to take. professor ed hawkins has summarised the average global temperatures in this simple graphic, with 1850 on the left and the present day on the right.

what you see from 1850 up to 2018 is that global temperatures over that time have risen by about one degree with lots of variations from year to year. these rising temperatures will lead to more and more extreme weather. it certainly has been extreme recently. australia has just suffered its hottest month on record with wildfires in the south, floods in the north and temperatures of nearly 50 celsius. at the same time, the us is being gripped by a vortex of polar air. here temperatures have dropped to nearly —50. injapan, severe and unpredictable weather events happen yearly, making precise weather information critical for disaster preparedness. typhoons can bring transportation to a standstill with highways being closed and aeroplanes and trains halted. 2018 saw particularly violent weather. lastjuly, the city of kumagaya hit record temperatures of a1.1dc and in the same summer, heavy downpours led to floods

and mudslides that left 225 dead. over 8 million people were urged to evacuate. monitoring rainfall is hard and relies heavily on whether radar systems which you don't find everywhere and which only have a certain range. at weathernews here injapan, a new system is training artificial intelligence to work out rainfall from satellite images instead, allowing for rainfall approximations across the globe. this is the world's largest weather provider. it has 3,000 weather monitoring sensors and two satellites. it broadcasts rolling weather reports from its office in chiba city. but weather forecasting relies on having as many sources of data as possible so the company also gets its information

from its customers. everyday users of the weathernews app chat about the weather and upload 20,000 photos of their current weather conditions. using a combination of more ai and human moderators, these photos and texts are turned into real—time weather data. a kind of cloud sourcing, if you will. as well as providing weather forecasts for us ordinaries, weathernews also provides bespoke services for airlines, for example, to do with areas of turbulence on the flight path and the best ways to avoid those — whether you go over or under them — and also, interestingly, the best times during the flight to serve the airline meal, when it's not so bumpy that you end up with all your food on your lap. however, the biggest business is collecting readings from ships and then advising them on the best trans—ocean routes to avoid the worst of the weather. weathernews told us that they can save a large cargo vessel up to 5—million yen in fuel per trip.

but this place doesn'tjust deal with weather prediction. it now provides a potentially lifesaving service for another type of extreme event. the 2011 tsunami claimed more than 18,000 lives in japan. but it was found that the collision detection radar on a japanese coastguard vesseljust off the coast of fukushima had actually detected the oncoming wave. believe it or not, radar systems had never before been used to detect tsunamis. we have installed 28 radars along the coast, all overjapan. these radars can detect a sea level difference of between three and ten metres at a distance of 20 kilometres. if we can detect a tsunami so we have a space to evacuate for ten or 15 minutes. that's very much valuable time for the people to evacuate. and as well as warnings about what's

going to happen in the immediate future, weathernews is also looking to take advantage of longer term predictions too. as the climate changes, some are spotting new shipping opportunities. as the arctic ice recedes, a new route is becoming more accessible. it's becoming possible to transport goods by ship from japan to europe through the vilkitsky strait in the arctic ocean, rather than going all the way around africa. in order to make that route safer, weathernews has released one of the only satellites that can photograph the arctic, to provide more accurate sea ice information. then there's the special service that they provide for convenience stores where they will advise what to order in based on tomorrow's weather. for example, if it's going to be hot, more ice cream. it is going to be really hot, more sorbet. and the extreme heat is a worry for next year's tokyo 0lympics.

discussions are under way to start the race at dawn to try and prevent deaths from the intense heat. here at weathernews, they're working on a system that will predict the best places for spectators to find a shade and breeze. the amount of data required to predict even tomorrow's weather is enormous but for a commercial operation like weathernews, finding new ways to use that data means new services and ultimately new income for a very expensive business. hello and welcome to the week in tech. it was the week that uber launched a boat service in mumbai to beat the city's notoriously bad traffic. sportswear brand puma started searching for people to test its new self—lacing shoes, and 230 new emojis were approved for universal use with dozens of new accessibility—themed icons including wheelchair users, prosthetic limbs and service dogs. there are also new food and animal

emojis and a drop of blood to represent menstruation. it was also the week that reddit, the so—called front page of the internet, was reportedly raising hundreds of millions of dollars in funding. chinese company tencent is said to be leading the funding round which could see reddit valued at almost $3 billion. a police trial using facial recognition in the uk has seen one man charged and sent to prison. the met police were using the technology over two days in east london. another person was fined £90 for verbally abusing the officers after trying to avoid the cameras. apex legends is being called the first real battle royale challenger for fortnite after being played by over1 million people in the first eight hours of its release. the game from electronic arts and respawn was also the most watched game on twitch. and finally, saudi arabian citizen and humanoid robot sophia now has a little baby sister you can take

home thanks to a successful kickstarter campaign. hanson robotics hopes sales will encourage girls to explore careers in robotics and coding. worried about bots sending e—mails from your account? use this easy method to be notified quickly if they get in. add a fake e—mail address to your contacts. if a mass mail goes out, you will get an undelivered message for the fake address. and then we recommend changing your password. last year, tik tok was the world's fourth most downloaded app, topping instagram and snapchat.

the company is now valued at 75 billion dollars, that's more than uber. but if you still haven't heard about it, don't worry, i will fill you in. the bulk of the users are in china and most are in their teens or 20s and they seem to be doing things like this. excuse me a moment. so now i'll need to use a filter to make my hair ginger. 0oh, red doesn't seem to be an option. shall i be green spice? i'm sustainable spice. let's go with that, that's very 2019. let's go! # slam it to the left if you're having a good time. # shake it to the right if you know that you feel fine. what am i doing? you can lip sync to your heart's content although it's better if you know the words.

as well as use stickers, filters, or add a spot of augmented reality. 0ryou can simply post what you wish. but if you're struggling to see the point in all this, well, millions would disagree. we have seen this app grow since chinese tech firm bytedance bought its predecessor musical. ly. and now, according to research by the south china morning post, it has 500 million active users. with1 million fans, british comedian laura uses it to post sketches and has become involved with hosting events for the company as her followers have flourished. what i like most about tik tok, it's short, it's concise, it's easy to use, but there's all these different features, you can duet, you can react, react to other people's videos, and i think the big appeal is you can copy other people's soundbites so i can do a sketch using another comedian‘s voice and people can do the same with mine. hi, what can i get for you today? they have some famous voices there, some old vine people there. lots of different soundbites to choose. vine may have died a death but clearly other platforms

like this are thriving. but on the flipside, this is just another compelling app taking our eyes away from well, the real world. and that is a distraction that the uk government this week highlighted to parents. they released new guidelines on screen time including banning devices at that time and mealtimes. meanwhile, the appetite for these apps seems to be growing. you just have to hope they'll be used sensibly. lucky i've only got one fan. that was sustainable spice and i don't feel the need to say anything more about that piece so we'll move on. now, we've been banging on about virtual reality for an age and while it's failed to ignite the imagination of consumers — i mean, how many vr headsets do you own, for goodness sake? it has started to catch on in areas like simulation, training and healthca re. marc cieslak has been

to sheffield to investigate. make sure it's tight. that's it, yep. keep your grip in your right hand. yes, got it! so, what i see, there's different types of games and the game that i was playing was a bow and arrow one. and you have a bow in front of you and you need to pick it up and get that arrow behind you and thenjust let it go and it shoots and pops it. here at sheffield's children's hospital, they're trailing some surprising therapeutic technology. with certain types of injuries, exercise can be a vital part of rehabilitation, ultimately leading to the patient getting better sooner. the problem is getting children to perform these exercises isn't always easy. right back. ooh.

most of our kids have quite a long—term condition that they need to carry on doing their exercises for sometimes several years. keep the tight grip on the right. yep. they're doing the same things day in, day out, it gets really boring, no—one wants to do it, sometimes it's painful, it's just not really fun, they want to be outside doing things with their friends. which arm is the injury, the left or the right? making use of virtual reality, researchers from sheffield hallam university have developed a system that they think will make children more likely to perform rehabilitation exercises by disguising their treatment as play. this version of the project is for upper arm injuries, primarily. the injuries that are normally from burns or an accident that they had from a fall. remember to swap hands, that's it. remember to look up as well and see where you're at. so how did you hurt yourself? i burned myself with a cooker lighter.

i scarred my arm and my belly. we arrived at the decision to make the two games the scenarios of climbing and archery. based off talking to occupational the kind of movement they needed the patients to do. one of the motions that they needed to do was reaching behind your back and, kind of, a lot of upper arm movements. and so i thought, i wonder if archery would work. because there's a quiver behind your back. you do the same motion of reaching behind to grab your arrow and then you get the added bonus of pulling back the bowstring and then we looked at things like climbing and we thought that was a natural fit as well because there was a lot of overhead motion, so you're really reaching out. the climbing. it feels...it feels realistic. while harry is being treated for burns, emily here has an entirely different issue. emily's got a hereditary multiple exostoses. so it's like a hereditary disease that she's picked up from my husband, my husband's side of the family.

so it means that she has extra bone growth. let's go for a higher one. well, it's really fun, because you're not seeing, like, stuff that you usually see every day, like you're seeing a whole new kind of world in it. if you have a big imagination, then it definitely makes it bigger. it's kind of a bit more playing than exercising, even though you are still doing your exercises, like, it's fun as well. do you need a break or anything like that? is your arm tired — or? no, it's fine. she didn't find it easy. whereas before she would have given things up very easily. but she wanted to keep going. she wanted to pop another balloon. yes, got it! and she wanted to reach that next thing. but she's just been an absolute trooper. she just has a smile on her face every day. so it kind of encourages me to be positive. there we go. we've had kids come in who can only get their arms up to here and they come in straightaway and they're picking

the arrows up and getting full range of movement and not even noticing. and then when we've interviewed them after they've said that they didn't even notice any pain. so it's been a big shock to me how well actually it has worked to do what we needed it to do. now, i don't have an injury, but i'm going to give this vr setup a go and see what's it like when i put the headset on and what it feels and plays like. here we go. as a vr experience, it really does the thing, because it's really quite fun. after playing for a little bit, as well, you can understand how, when the children are playing this, they get so wrapped up in the experience that they forget that this is actually helping them recover. this project was born out of work ivan and his team had already created, which used vr to help distract burns victims as a form of pain management. it's early days for this technology, but they hope it could have a wide variety of healthcare applications.

looking at other aspects such as pain reduction for burns, we're doing some work with amputees, learning how to use a prosthetic arm. so it's a lot of experience—based training. and we have a couple of other projects that we're currently just looking at — around, kind of, stroke and chronic pain as well. but the final word goes to emily. she might be a fan of the vr, but i do wonder if she'll be pleased to get the external fixator on her arm removed. will you be pleased to get that off? yes. it's quite annoying. brilliant. that was marc cieslak in sheffield. now, this weekend is one of the biggest dates in the british movie calendar. the bafta film awards are taking place at london's royal albert hall. and what better way to celebrate than by chatting to one of those nominated in the best visual effects category for their work

on fantastic beasts: the crimes of grindelwald. i can't move against grindelwald. it has to be you. technically you can do just about anything these days. so i think more of ourjob, at what we're set the challenge by bothjo rowling's scripts and by david yates is is to creatively push the envelope and use the technology to aid that. we had some very specific things thatjo had written in the script, but we also had, like, newt's hospital, where it was maybe a bit, a few were more background creatures that we could go on some of the same journeys that we did with the case. but one of the key creatures was the zouwu, you know, it was fairly specifically written as like a chinese tiger—like creature. one of the animation artists built it and animated it and got it moving. and then, really, it was a voyage of discovering of working out how it would move, how it would look, what its tail would be made of, et cetera, et cetera. in the script, it described it as it

runs 1000 miles a day. tim and i were like, my god, wow, how are we going to describe that, how are we going to show that? so we came up with the idea that maybe it could magically leap and then time — distort space—time and land in a different space. so it could cover a large distance very quickly. you know, it's over a year's work forjust that one moment in terms of concept and working out how on earth to do it. nagini. the moment has come to take our rightful place. nagini appearing when we read the script — we went, oh my god, nagini's a woman in this film, not a snake. we had to come up with an authentic way to turn a woman into a long tube. how would we do that to make it feel real. we came up with the idea that, really, maybe she's almost consumed by the snake, rather than physically extending out.

you recall her being wrapped in her own coils, disappearing and and then coming out as a snake. so we had a contortionist. claudia kim who played nagini, we showed her what we were planning and what she acted the first portion of the shot, then we had another contortionist in there who was, you know, dressed in a matching costume and she did the first portion of the shot, so it's for real — she bent over backwards and put her head through her own legs. got shot elements of claudia kim kind of pushing herself along the ground and turning her head up, matching kind of what we had done, which was then glued together with a full cg version of the human character and a full cg snake. so, again, all in all it was about 1a months worth of work for that one moment on film. i don't think you have seen a woman pull into a wall and turn into a snake before. so, really, it's trying how to get those moments over, feeling as grounded

and real as possible. we wanted it to feel as if how it would feel if you were physically they are, rather than feeling like an effect. i think that is what the technology gives us, the ability to do that. the wizarding and non—wizarding worlds have been at peace for over a century. grindelwald wants to see that peace destroyed. fa ntastic stuff. and,of course, we wish all of the bafta nominees or the best of luck for the big night. next week we'll have more awards contenders for you as we continue our deep dive into the world of visual effects. and before we go, for this week — this. it may not be as graceful as a figure skater or as fast as a speed skater, but unlike many people, this robot taught itself how to skate on ice. at the computational robotics lab at eth zurich, professor stelian coros and his team developed a modular robot with 3—d printed parts. each leg can be built for any type of locomotion —

from walking to rolling to ice skating — and each robot can have any number of legs. they then wrote algorithms that described the physics for each type of movement and terrain. the only thing we tell it is how one ice skate behaves on ice. in particular, the fact that it's free to move in the direction of the blade and it has high friction forces in that direction. after this, the robot figures out entirely on its own how to move on ice. using this machine learning approach, different robots can learn to autonomously navigate any terrain. researchers hope this will lead to affordable, easy—to—design robots that can be used for search and rescue operations, to inspect dangerous sites, and even for deliveries too difficult to reach areas. i envisioned a moment in the not too distant future where it will be as easy to create robots as it is to currently make structures out of lego blocks, for example. i think this is a really exciting motor skill that we would like robots to learn, not necessarily because it's useful, but rather because it combines

are many different challenges into one beautiful performance. very, very cool. and that's it for this week. don't forget that we live all over social media. so wherever you are you'll find us, instagram, twitter, facebook, youtube, we will be there waiting for you. thanks for watching. and we'll see you soon. hello there.

it has been an improving story today, really. still windy out there, but the winds are easing down and that is because our storm, storm erik, which was earlier to the north of scotland, is heading towards scandinavia to take the worst of the winds away with it as well. the next weather system is pushing in the cloud and turning the sunshine hazy across the south of the uk. sunshine around elsewhere and some showers as well and gusty winds this afternoon, gusts of 50 miles an hour or more in northern england, especially on the pennines but those should ease down a little. strong to gale force winds and plenty of sunshine and showers, mainly northern ireland, wales, south—west through the english channel, the showers in scotland becoming fewer but we have rain in the far north of the country. decent temperatures today, 9—12 degrees, mild, but we still have those gusty winds. the cloud continues to thicken in the south—west, turning wet here and the rain develops more widely, pushing north to north wales and across towards the wash. north of that, the cloud will be more broken so it will be colder and there may be a touch of frost and icy patches as well. wet weather in the far north of scotland and that is the wet

weather system that will buckle its way down towards northern ireland tomorrow. ahead of that for england and wales, a messy start to the day with the first weather system, cloud, outbreaks of rain and snow over the tops of the welsh hills. it will turn showery quickly, so too in the south—west, but the wet weather and cloud continues to drift down to east anglia and the south—east. rain, could be quite heavy, gusty winds for northern ireland, otherwise some sunshine around, much lighter winds, you will notice the difference tomorrow but it will feel chillier, temperatures around 7 degrees, and we still have the rain for northern scotland, the same weather system moves south, bringing gusty winds and wet weather across wales and southern england. it is gone by monday, high pressure is building so a chilly start to the new week, maybe a touch of frost around. patchy fog for wales, perhaps into the west country, and some stronger winds on north sea coasts, bringing a threat of a shower, but winds will be lighter and we will have plenty of sunshine. it should be a dry day, temperatures away from the south—west rather low at 5—7 degrees. high pressure will dominate into next week which means lots of fine and dry weather, sitting to the southeast

of the uk until we draw in milder, southerly winds. premier league but i think united will win 4-1. 3-1, liverpool. two to mo salah and someone else with another one. good afternoon. a controversial ferry contract, awarded to a company which had no ships, has been scrapped. seaborne freight would have earned £13.8 million under a deal with the department for transport intended to provide extra capacity in the event of a no—deal brexit. the transport secretary chris grayling had defended the deal, saying he would"make no apologies for supporting a new british business.
