vulture investigation continues in vulture after please identify the source of the nerve agent novichok. it was found ina the nerve agent novichok. it was found in a container inside the house of one of the victims. what an afternoon of spot ahead. that england game against belgium. straight to wimbledon first with the women's singles final. the highlight this afternoon. we could be set for another epic indie men's semifinal as well. let's cross like that now. many thanks. astonishing that we are here with serena williams in another wimbledon final in light of everything that she has gone through since the birth of her first child. the health complications that followed since the birth are astonishing. it is astonishing. in the absence of some of the top seeds which we saw fall away in the early
rounds, we're got a final worthy of the championships this year. it is a repeat of the 2016 wimbledon final. she's hoping to get the better of serena williams. she had a great year two years ago, beating serena williams in the australian open final. she lost to her rat wimbledon later that year. it will be fascinating when those two renew old rivalries in the final on centre court later on. it depends on the conclusion of the djokovic nadal match. novak djokovic came away from that to — one up when they walked off late last night so they will resume on centre around one o'clock
today. that means the traditional to be the start time of the women's final is likely to be pushed back. but no two players have meant more. the 52nd meeting between the two and away it was going last night, we are in for exciting finish. you can see it all across bbc two. at chelsea. he replaces. he describes it as a exciting period in his career. it is not the match they wanted but england will end its world cup with a play—off against belgium. the two teams met in the group stage. that match as many fringe players involved. sometimes it is not always a good decision for people to play. we're back to think who can give us
the best performance so it won't be exactly the same starting 11 but we would like to make as few changes as possible. crickets. both fell victory to the spin... that is the sport for now. up next is clicked. -- click. fed up of the football? your team has gone out? well let's talk cars instead. this week we are at the grand prix. we are in a do—it—yourself driverless car in india and someone getjen a new umbrella. the seconds wound down
before the start. 24 drivers step hard on the throttle. formula 1 has been at the cutting edge of technology and design since its creation in 19116. welcome to the pits. every year teams compete fiercely to outdo each other in aerodynamics, data communication and materials, all with one aim. to make their cars go really, really fast. and they do a really good job of making them that, as we are finding out here at the austrian grand prix. lewis hamilton's ride. what is even more impressive is that this whole show is permanently on the road with cars, teams, engineers and scientists moving from country
to country and track to track. now these are the most expensive motor homes i've ever seen. each one of these is a glory and theyjust drive them to the next formula 1, stick them together, zip, zip, zip and that is it. and ahead of the base here in spielberg austria the cars are being prepped, tweaked and tested around the clock. the sages are the current world champions and, like every other team here come they spend millions on their car and developing the technology that will hopefully win them the race. but what you see at any grand prix is just the tip of the iceberg. it takes hundreds of people to develop the technology. so we went to mercedes hq to find out what really goes into winning a race. away from the track, the people, the planning, the preparation and the precision are pivotal. hi, i'm from the bbc.
hello. can ijust put a security sticker on your phone. of course, no problem. so we are allowed to film here but i mustn't take pictures on my phone! there is clearly a lot at stake here so it is no formula 1 is notoriously secretive. but today we have got some behind the scenes access. this business is big bucks and millimetres and milliseconds matter. this is a chassis numberfive, last year's winning car. in fact it hasn't even been cleaned since its last race in abu dhabi. but the thing that is most striking standing next to it is the amount of detail there is everywhere throughout the car and after each race, if there is something they are not happy with, it will be perfected.
this was a winning car last year so it has been very successful but you are obviously not happy with it because you are working on a new one. so what do you think needs to be improved? we are never happy with it, as you say. this is lewis's, from last year. it was the first car we made on the back of a really big regulation change. we worked really hard on all those little small bits you sit we worked really hard on all those little small bits you see around the car, which are all the aerodynamic bits and pieces. it is made up of lots of little small bits. yeah, every little bit at a job and we put it in and each one is about optimising the airflow around the car. but we are not happy with it here because we focus on so much on that week now need to do a lot on the packaging to make it much tighter. the tighter you get it the better you can get the aerodynamics around the car.
on top of that as well we think we can do improvements around the cooling. those big black ducts around the side is where the echoes in to cool the engine. we think we can do some do some improvement around that area as well for next year. well there is so much money at stake here. how much does it cost to create a car like this? from the beginning of the process, all the way through, what sort of figure would you put on that? well i can't tell you the exact figure but what i can tell you is it is in the millions. are we talking tens of millions? tens of millions, yes. tens of millions? over 50 million? close. crikey, i wouldn't want to pay the insurance premium on that! the operation here goes way beyond the car itself though. welcome to the race support room. when the race is actually on 16 members of the team are allowed to be at the track. so this provides the opportunity for more people to be looking at the data and making sure that vital advice can be provided. on the screens they will be looking at a feed from the race. they will also be looking at feeds from within the driver's cars, plus all the vital data they want to act on. and if they want to communicate then they simply do it through a pair of these.
lap times, gps data, everything can be tracked and analysed here where 5,000 different data points are being assessed. information from races in europe taking just 0.1 of a second to reach here or 0.4 if the data is coming from australia. meanwhile this lot are busy practising at speed. over 250 of these trials take place ahead of the season. they make it look easy but inevitably it is not, as i can tell you first hand. oh, no! it is meant to be so quick but i clearly wasn't. meanwhile... living life in the fast lane. thank you, laura. and by the way, this is how you really do it. this year mercedes has got
it's pit stop down to an incredible 1.85 seconds. now that is quicker than it takes to say 1.85 seconds! it's a finely tuned operation and the engineers practice over and over in the days before each race. it is a bit of a ballet and the ergonomics are quite important because we are speaking of 20 odd people around the car, trying to do a job in two seconds. and if you start banging into people then you lose half a second, a second and then the strategist can't get their numbers right and then you don't get the position you need. the human element to this ultrafast manoeuvre is accompanied by technology, individually developed by each team. even the hydraulically powered wheel guns are a closely guarded secret. i hear they are quite expensive. they are expensive and they are under an awful lot of
pressure so we are changing the internals a great deal. do i hear about £30,000 each? i wouldn't know the exact cost but that sounds quite low to me. we're going into the mercedes garage now. keeping the pit crew safe is of utmost importance. these lights for example let the crew know if the cars have become electrified, stopping them from getting more than a nasty shock. and then there is what goes into the car. more specifically, what comes out of the cars, which is monitored by track—side labs and high—end scientific equipment. between every session the cars are given the equivalent of a blood test. the oil and the fuel is taken to see if it is contaminated and that might give you a clue as to the state of the engine. and that is done in the fuel lab. the oil is put into a spectrometer which tests for different metals in the fluid.
the amount of a specific metal present can reveal if a particular part of the engine is grading too quickly. yes, these may be some of the most skilful drivers in the world but i wonder if even they would struggle with driving in david reid's neck of the woods. ok, here we go. this is maximum chaos! this guy has just overtaken me on the inside. it's crazy! a car sandwich. yeah, that's me. thank you. diving here is tough. i reckon if western autonomous car makers came here they would hide in their hotel rooms. but indian inventors, the see the chaos on the roads here and they want to take it on. look at this mobile footage. this rickety second—hand suv has been made single—handedly into a self driving car. it's a bit rough but it
makes it down the sort of road that gets wing mirrors very worried indeed. this is the man behind it. a us—educated a! specialist. he says the maths that navigates his car, the algorithm, has been designed specially for india's nightmare roads. indian traffic is very chaotic so it is very hard to predict. once you have solved that prediction problem then you can apply that in any environment and it will work because you already tested it in the most difficult conditions possible. today there is a hitch. the car is refusing to drive itself so he takes the wheel. top—end driverless cars cost a bomb. they are developed by big teams, have pricey radar and lasers and use big data maps to find their way.
this one is cheap but not short on brains. his off the shelf cameras talk to an algorithm that reads the road even without maps. india's government is against driverless cars because they fearjob losses but the technology being developed here could still travel far, especially with the advent of artificial intelligence. now, whether or not at some time in the future will have driverless cars is very debatable. however, the same technology can be used to make india's roads safer. many here place their faith in dashboard mounted gods to protect them. but with 150,000 dying on india's roads annually, driver i, a hazard warning system developed in bangalore might also merit a look in. so why did he go there? it is too close and it was detected. and it is just as well because they were policemen! driver i is a clever
back—seat driver. so this is the front camera. it measures acceleration, orientation and has ag, but also artificial intelligence. it learns what is safe and what is not. it is helping indian truckers drive better. we are tracking every single bit of the road and we are basically measuring any unsafe and identifying any unsafe event. we are actually identifying what the driver's manoeuvre is and if the driver's manoeuvre corresponds to a positive manoeuvre or it was actually something that the driver can improve upon and the driver did something that something could be considered unsafe. like our run—in with the cops, we got the video because driver i sent it back when the warning sounded. one rather surprising area where driverless technology is making inroads is actually off—road. in chennai, one of india's
main car makers is developing self—driving tractors in response to low crop yields and the lack of farm workers. tractors can work around the clock, just what you need when you are up against a short window for sowing or harvesting. it has to happen right at that time otherwise you can actually use the intelligence of the season. it's not an easy piece of equipment to drive because you don't want the lead wheels to run over the seeds so you need consistent operation and that can only be done by technology. on or off road self—driving tech has incredible potential, helping out farmers, disappearing unruly drivers and harnessing chaos as a test—bed for even smarter systems. hello, and welcome
to the week in tech. this was the week that facebook faced a fine of $500,000 for breaches in the cambridge analytica data scandal. and we've learnt the scale of apple's autonomous vehicle ambitions. stealing trade secrets has revealed that 5,000 of the company staff know about the project. the smartphone supremo has remained laboriously tight—lipped on the issue. across the channel a family in france have become the first to live in a 3—d printed house. their cement filled home in nantes was built in just 5a hours. but the city's university and council behind the project think they could do it all again injust 33 hours. it's curved walls make the property less humid and the construction costs were 20% cheaper than using traditional methods. it was also the way chip—maker nvidia showed off its photography skills.
using deep learning it has trained it a! to fix grainy or corrupted images. amazingly it has learned how to do this having only seen corrupted ones. this means it could make restoring your pictures easier in the future. magic! and finally mit have designed a musical instrument specifically for space travel. it contains chimes that are equipped with gyroscopes that change sound depending on how they are shaken. it allows budding astronaut musicians to beat the box in zero—g. the stats for formula 1 are mind blowing. these cars come around this track at over 350 kilometres an hour and that is why 350 million fans tune into these races. but attracting new viewers is a bit of
an issue for this sport because, watching these cards go around and around and around and around... can get a bit boring. formula 1 are aware of the problem and part of their strategy is to use all the latest tricks and technologies and technologies to pull in new fans, especially those who play racing video games and are used to feeling like they are really sitting in the driving seat. sport broadcasting technology is moving at such a pace. we are talking about 3—d, 360, virtual reality. that is a big talking point at the moment. mixed reality is quite nice as well. whether that is bringing in actual footage against the cg! world. the demographic for a formula 1 fan i believe is a middle—aged man. we want to make it available for young people, boys and girls, all sorts of people. this year every formula 1 car has one of these cameras right on
the front. that is correct. why have you done this? to give the public a more interactive feel. you can actually go wherever the action is and if you record it you can watch it back at whatever angle you want. and have you tried this? what's it like when you actually look through the goggles? we haven't found anybody who hasn't been wowed by it. it is our intention that you can pick your favourite driver and have an experience with him going around the track. but while this may be a great experience for the viewer, the teams which consider every centimetre of these cars might not be so happy about formula 1's mandatory addition. the original camera we used was the size of a cricket ball but this obstructed the driver's vision and so we repackaged it and this is the design we came up with. and i think the balance of what you achieve
the good outweighs the bad. and the experience is not just about what you see, it's also about what you hear. as a formula 1 cars have developed, that iconic engine has died down. steve and the team plan to read it up once more. it has been a long—held desire of our audio department to mount a microphone in the exhaust. how hot does it get inside the exhaust? up to 360 degrees. this is a microphone we had on lewis hamilton and it it touched the exhaust and you can see what happened to it. now it has to live outside of the bodywork. it has a heat resistance of 1000 degrees, i think. when they come to a corner and they change down and they make that engine noise, before it wasn't very emotional. now when you listen to it it really is a rasp. it's a really emotional sound. we have had lots of feedback from around the world, from broadcasters, and everyone loves it. even broadcasting these races is a huge operation, from australia to bahrain, to china, the broadcast centre needs to be built in a matter of days to beam this race out to more than 200 countries. the most amazing thing about this
broadcast centre is not all be screens and all the technology, impressive though it is. it is the fact that at the end of the race you just fold up these desks, put a lid on it and it is already in a load of aircraft containers ready to ship to the next race! there is about 200 tonnes of equipment in this building. it takes up about two 747s and 2a trucks, effectively. how quickly can we get from one race to the next race? i think it is the biggest mobile broadcast centre in the world that moves so often. we come along with a concrete patch, they provide us water and away we go. we build our whole... last sunday you finished a race and by thursday you have come all the way to austria
and you are up and running. exactly. and next thursday we will be in silverstone, fully ready... look at the man! he's not even breaking a sweat! it's like, yeah, whatever. and actually it looks like the most stressfuljob this week is being done by our star in a reasonably priced, if somewhat weather—beaten, car. yes, ben, lam braving this hurricane in cologne, germany to experience europe's boast advanced weather testing centre forecast. ford have built the $108 million facility to see how it popular models fare against the most extreme conditions on earth, from altitude, humidity, winds and driving rain.
there are three wind tunnels here. and capabilities of testing up to ten cars at once. i pretty much control this facility and i conduct those tests. we have sensors for relative humidity, temperature and for the air speed which is measured from differential pressure from the nozzle. first we are going to see what it might be like to drive your car in a rainforest. it get up to 55 degrees in this room and the humidity goes up to 95%. this is one of four temperature controlled test chambers, complete with birdsong and fake palm trees to simulate a tropical environment. it is baking in there! that is so hot! from extreme heat to extreme cold,. oh, that is the snow room. these doors are really heavy. it's about —17 degrees in here right now. but the temperature can be set to go as low as —30 degrees. —30 degrees of course is rather important for cold starts, it is
important for issues for the heating system, for comfort and for safety of course because we have a defrosting of the windshield. they are also testing how the windshield wipers operate under heavy snow. the snow is falling from above and can test the maximum stress on part of the car. this is impressive! it is testing the weight of the snow on the car. because this is actually a realistic situation in some parts of the world, to get a big snow boulder on the... mirror! next we're going to see how cars are tested in hurricane conditions. we have climactic wind tunnels so we always control the wind speed to simulate that the car is actually moving on the roads. so it is actually 156 km winds out there now. it can go up to 160 kilometres an hour. it is testing the automatic function of the windscreen wipers. whether or not there is an equal amount of time going between each blade. the tunnel doesn't just test the rain and wind but also the
effect the sun has on the car in extreme conditions. it is set up with 28 spotlight 4000 watts bulbs to mimic sunlight. the solar system is always interesting when it comes to heat that affects our power train and performance. that really looks like being outside in the bright sunlight. it's pretty much brightens my day every time i can use it! the ability to test cars at high altitude while also simulating challenging weather conditions is the unique feature of the test centre. they can be types of 5200 metres. engineers even have to take breaks when they are finished working in this tunnel. more than half of our vehicles are sold in markets with altitudes of more than 1000 metres. we can also simulate
here pulling a trailer up the hill on different altitude levels. testing the power train regarding what is happening in terms of temperature, how that is developing and making sure that the car is safe. well, we have seen everything here and ifor one am looking forward to getting back to some nice british weather. that wasjen and that is it from the austrian grand prix. i hope you have found it as thrilling and strange as i have. you can see a lot more photos up on twitter. thank you very much for watching and we will see you soon. it's a pretty straightforward
weather story to tell. you if you got out tight pants you will not be disappointed because it looks likely to stay warm and sunny. hot for some others. in week with a front will bring cloud and showery outbreaks of rain. gradually crowding over into eastern scotland and the borders. 16 to 23 degrees. in the south we could seek 28 degrees. that is going to lead to quite a one night with those temperatures not falling very far. mid—teens. at the same time our weather front will bring showery rain into northern ireland, western scotla nd rain into northern ireland, western scotland and perhaps into aberdeenshire by dawn on sunday morning. we start of sunday with that weather front out into the north—west but for most of us this week and it is hot and sunny. it will stay like that. whatever you do, enjoy. good afternoon.
police scotland has begun a criminal inquiry after a paraglider, part of protests against donald trump, came within yards of the president at his golf resort in ayrshire. in a major breach of security, the greenpeace protester flew over the turnberry course shortly after mr trump arrived there last night. protests against the visit are taking place across scotland today. from turnberry, catriona renton reports. protesters are calling today a festival of resistance, a national demonstration. here in edinburgh, more than 10,000 people are expected to gather on president trump's second day in scotland.
